The most durable varnish for wood. Features and types of wood varnish for exterior use. General information about wood varnishes

Wood varnish - what can and should it be? How to choose it correctly? What should you pay attention to first when buying wood varnish? These are the questions that consumers always ask before purchasing paints and varnishes. In reality, the question of choice is not as difficult as it may seem at first glance, despite the fact that there are very, very many of these products on the construction market. When purchasing, it is very important to take into account the specifics and properties of the object or surface that you plan to varnish. You can’t go to the first store you come across and buy a wood varnish that suits you in terms of price or color, and not take into account the technical characteristics of this paintwork material.

Painting wooden objects indoors is necessary to protect them from fungal growths, mold, insects, or as an option for decoration, restoration of household items. Exterior painting primarily serves to add tone, matte or, conversely, shine to the facade and other outdoor surfaces. Any wood varnish, including acrylic, is selected taking into account the texture, properties and characteristics of the wood species. Surfaces need to be varnished in several layers. And in cases where the rock is too porous or has many scratches and small cracks, preliminary priming and puttying is required. The degree of load on an object or surface plays a very important role, therefore, when choosing a material, this should be taken into account first.

What you need to focus on, or Criteria for choosing varnishes

Wood varnish is used to treat and protect wood from various damage and putrefactive processes. Available for internal and external work. They are very different in composition, technical characteristics, properties and scope of application. Therefore, before buying a varnish for wooden surfaces or objects, you need to understand, at least in general terms, which one is more suitable in a particular case. When you come to a hardware store to buy varnish, take the time to read the instructions and conditions for using the composition you prefer, and ask whether it meets your selection criteria.

Varnish for interior or exterior use

Think about where you will use it. If indoors, you need to buy varnish for interior work. If you plan to varnish a facade from the street or an object that is located outside the house, then you need wood varnish for exterior use. Otherwise, if you choose paintwork materials for interior work and treat an outdoor object with it, the varnished surface will simply fade or crack.

Wear resistance

For example, you need high-quality varnish for parquet. In this case, the requirements for wear resistance must be taken into account. Pay attention to the line of two-component polyurethane-based varnishes - this is the most suitable paint and varnish material for parquet. It has a high wear resistance, that is, this composition is resistant to abrasion. You can also buy water-based wood varnish for parquet - it is suitable for treating floor surfaces and creates reliable and durable coatings. It is not recommended to buy nitrocellulose - it has the lowest wear resistance coefficient and is not suitable for parquet.

Glossy and matte

The degree of gloss when choosing is also very important when it comes to the interior. Every home has objects with the same degree of shine, so you need to buy varnish based on the requirements for other household items or room design. This is not obvious, but the degree of glossy coating largely depends on the method of applying the paintwork and on how well the surfaces are sanded. The color of the substrate also contributes to the degree of gloss. And, of course, one cannot help but take into account the shade of the varnish.

Toxicity

Most paint and varnish products are dangerous for the human body because they contain solvents: these are nitro varnishes, polyurethane-based varnishes, acrylic wood varnish for exterior use, and polyester compounds. You should work with such materials in special workshops (painting shops), in non-residential premises, and if there is a need to use them in a residential apartment, then during the repair work associated with applying varnish, residents must leave the house for at least a few days.

Drying speed

How long will it take to coat the planned surfaces with varnish? Few people think about this, but on average, wood varnishes for interior work take about 6 hours to dry, sometimes it takes a day to dry completely. Therefore, many people try to get all the painting work done over the weekend. Water-based wood varnish is considered the fastest-drying, and nitroglycerin-based wood varnish is considered the longest-drying.

Componentity: what it can be

Most residents of our country know only one-component, ready-to-use varnish. After applying this substance to the surface, the solvent contained in the composition evaporates and only a dry residue remains. Professional varnishes (also called wear-resistant) are multi-component products. When working with them, you can mix the necessary components, for example, add a solvent and a hardener. This composition tends to polymerize due to the chemical reactions occurring in it between the varnish substance and the hardener.

Self-priming

This refers to external self-priming wood varnish or a “primer + varnish” composition. In other words, not all varnishes can be immediately applied to wooden surfaces. The selection criterion, however, is not obvious, but, as practice shows, most varnishes require preliminary priming so that they do not peel off from the surfaces and do not form craters and waves on the varnished surfaces. Paintwork materials that do not require preliminary priming are called self-priming. They can be safely applied to the surface without any fear. This is very convenient when choosing and economical when purchasing (no need to buy additional soil).

Fireproof

The finishing of public premises, as well as private shops, firms, and companies often has special requirements; fire protection is one of them. The same requirements apply to paints and varnishes. Fire-resistant varnishes are produced precisely for such purposes, and to be more precise, the manufacturer must specifically issue a fire safety certificate for them. It is mandatory to use such a substance according to the technology specified in the document.

If you are guided by all the above criteria, choosing the right paint and varnish material will not be such a difficult task.

Features of paints and varnishes

Any paintwork material has its own characteristics and technical characteristics. A brief description of the most purchased ones is in the list below.

Polyurethane varnish for wood. It does not turn yellow during operation and has a high wear resistance. Does not change the original appearance and texture. It is very demanding on temperature and humidity: the temperature should be about 22 degrees, humidity - no more than 60%.

Alkyd and oil varnishes. Not as demanding on temperature and humidity as the previous one. They are easily and well applied to surfaces, including metal ones; the ability to penetrate into the pores of wood is good. The only drawback is the low wear resistance coefficient.

Acrylic varnishes. Used for finishing wooden surfaces. Acrylic wood varnish has a slight odor, similar to the smell of wet wood. Wear-resistant, resistant to cleaning using chemical detergents. Before painting surfaces with this type of varnish, it is necessary to first prime the surface.

Unscented varnishes. I would like to dwell on this product line in more detail. Many people are afraid of painting and varnish work due to intolerance to the smell of solvents and other components with strong unpleasant odors, which are also harmful to the body. Manufacturers in the paint and varnish industry have tried to create paints and varnishes that are completely odorless, and they succeeded.

They are produced on a water basis, so there are absolutely no solvents in their composition. Used for processing wooden surfaces. Produced mainly by foreign manufacturers. However, recently our domestic companies have also managed to create their own odorless product. How to use such varnishes? The algorithm for carrying out painting work is no different from using conventional ones. They are used both for priming and as the main paint and varnish material.

Quite often, the average consumer, when choosing paints and varnishes for wood, torments himself with various questions. What is the best varnish to buy? How to choose? What should you pay attention to? However, choosing a good and suitable varnish with such an abundance of assortment on modern building materials markets is not such a difficult task. When purchasing paint and varnish material for wood, it is important to take into account the properties and specifics of the surface being treated. You cannot, for example, just go to the market and buy frost-resistant varnish for exterior woodwork from the first seller you come across, without taking into account the characteristics of this paintwork material.

Working with wood varnish

Painting wooden products indoors is required to ensure their protection from the formation and influence of various fungi and molds, damage by insects, or for decorating or restoring wooden objects. Exterior painting is primarily used to add shine or matte to wooden facades and other external surfaces. Therefore, any wood varnish, including acrylic, must be selected taking into account the properties and texture of the wood. Surface treatment must be performed in several layers. If the wood has high porosity, small cracks or scratches, then it should be pre-primed and puttied. Also, when choosing a paint and varnish material, you should take into account the degree of load exerted on the object or surface being processed.

What should you look for when choosing?

Any wood varnish is designed to protect the treated wood from various damages, atmospheric influences and decay processes. Depending on the technical characteristics, composition, properties and scope of application, paints and varnishes can be intended for both external and internal types of work. Therefore, before purchasing, you should clearly understand which paintwork and varnish will suit you in a particular case. Before you go to the store, you should read the characteristics and conditions of use of a particular composition and whether it meets your needs.

Types of varnishes for wood

Most paints and varnishes are known for their versatility in relation to wooden surfaces (parquet, doors, railings, steps and much more). If you are interested in odorless wood varnishes, then you should know some of the features of paints and varnishes on the market today.

For exterior work, frost-resistant, moisture- and light-resistant coatings are mainly used. This is due to the fact that only such paints and varnishes are able to provide wood with reliable protection from aggressive weather conditions. It is strictly not recommended to use compositions that create an inelastic film when drying to treat wooden surfaces outside. Such materials include nitro varnishes. Also, paints and varnishes used for outdoor work must contain special antibacterial additives that protect the tree from insect pests and prevent the occurrence of putrefactive processes.

Alkyd varnish for wood. This coating contains alkyd resins and solvent, making it strong, durable and moisture-resistant.

Complete drying of the treated surface occurs within 72 hours, however, if faster drying of the applied layers is necessary, then you should choose paintwork materials that contain a hardener. In this case, drying of the coating is reduced to 24 hours.

The alkyd-urethane composition dries even faster. This is possible by adding urethane group components to the varnish. Such varnishes dry in 12 hours, not inferior in strength to alkyd paints and varnishes.

Oil varnishes. Such compositions are characterized by a high concentration of oils, resins and organic solvents. A special feature of oil compositions is the ability to change the color of wood from pale yellow to a thick chocolate shade. However, such paints and varnishes take longer to dry. Drying of the layers, depending on the ambient temperature, can last up to several days.

Nitrolac. This paint and varnish material is made from colloxylin, resins, plasticizers and volatile solvents. Nitrovarnishes are widely used when performing interior finishing work. Since this composition is quick-drying, the drying time of the layers is several hours, and in terms of strength, such a coating is not inferior in strength to similar paints and varnishes.

When coated, nitro varnish creates a transparent and thin protective film on a wooden surface, which reliably closes the pores of the wood, which, in turn, makes it possible to increase the water-repellent characteristics of the wood. It is worth considering that if you need a varnish that is completely harmless to health, then this type of paint and varnish material will not suit you, due to the content of toxic solvents in its composition. And the cost of such a composition does not suit everyone.

Attention! When working with nitro varnish, you must adhere to safety precautions and use a special respirator.

Water-based acrylic varnish for wood. Such paints and varnishes do not contain organic solvents, so they do not have an unpleasant odor and, therefore, are safer for indoor use. Treating a wooden surface with acrylics makes it possible to increase strength and also preserve the natural color and texture of the wood.

Acrylic varnishes are highly sensitive to changes in temperature and humidity and for this reason do not tolerate wet cleaning very well.

Epoxy coatings. They differ in that they dry quite quickly and can be used for work both indoors and outdoors. This is the most versatile paint coating, as it can be used to treat almost any type of surface.

Polyurethane varnish for wood. This material is characterized by water-repellent properties and high wear resistance. These characteristics have made polyurethane varnish one of the most commonly used materials for finishing wood surfaces, especially valuable types of wood.

Yacht varnish. It is considered the most durable among the coatings presented above. The protective composition of yacht varnish is highly resistant to the destructive effects of salty sea water and received its name due to its widespread use in the treatment of wooden boats and yachts. This semi-matte coating perfectly combines elasticity and hardness. The varnish is highly resistant to aggressive environmental influences, temperature changes and almost any cleaning agents.

Correct work with paintwork materials

Basically, special odorless paint is used to treat planed or parquet boards, however, some experts recommend using varnish for wooden surfaces for these purposes. In order to carry out high-quality varnishing of wooden products, pay attention to the simple instructions below.

Surface preparation. If the surface to be treated has not been varnished before, it should be thoroughly treated before applying the coating. If there is an old varnish coating, you just need to apply a new layer of varnish on top. Treatment of a wooden surface before varnishing involves thoroughly sanding the wood. After sanding, you need to remove dust from the surface, preferably with a vacuum cleaner, and you can move on to the next step.

Varnishing. Applying varnish to a cleaned wooden surface is done with a brush, roller or paint sprayer. Quite often, after processing, light wood becomes darker, while dark wood, on the contrary, turns yellow or redder. As a rule, such a change in the color of the wood occurs immediately after applying the varnish. Therefore, it is worth finding out in advance the properties of the composition used.

Different wood has its own hardness, which, in turn, determines the required number of coating layers. Soft woods, such as pine or spruce, require 3-4 layers of varnish, while harder wood requires two. If an alkyd composition is used, then 10% white spirit must be added to apply the first layer.

Consumption per 1m²

And last, but not least, the question of how much varnish is consumed per 1 m². Let us name the main criteria that directly affect the consumption of the composition on wood.

Wood. A wood surface with deep pores requires more material than fine-pore wood.
Sanding quality. Higher quality sanded wood requires less material.
Viscosity. The thicker the varnish, the greater its consumption per 1 m². For this reason, solvent or water is added to the varnish for applying the first layers if water-based paints are used.
Method of application. Lowest varnish consumption when using a spray gun. More material is required when working with a brush or roller.

The average consumption of varnish is 1 l/8-10 m², and when applying the second and subsequent layers it is less - 1 l/10-12 m². However, all the above criteria must be taken into account.

Often, special wood material is used as interior decoration. Lining is a natural, environmentally friendly material. It has great features and looks great too. It is often used to decorate verandas, loggias and simple balconies. Therefore, special requirements are placed on the material.

After all, wood is a “living” natural material that is subject to aging. It is afraid of high humidity, sudden changes in temperature, and various biological pests. Under bright sunlight, the unique qualities of wood are quickly lost.

How to cover the floor, lining, stairs, OSB in a wooden house?

To protect wood and wooden lining

the surface is coated with varnish, which ensures the safety of the material and its properties.

Those who neglect such treatment may find chips, cracks, abrasions and banal dirt on it after a few years.

What are the benefits of treated wood texture?

Preventing mold and rot.
Resistance to various mechanical damages.
Protection from sun exposure.
Increased fire resistance
Aesthetics.

During installation, lining is often treated with various special-purpose compounds: drying oil, antiseptic, stain. The original appearance of the material changes slightly. Coating the top of the lining with varnish refreshes and ennobles it.

Choosing the right product

Types of varnish

How and with what to cover the tree?

Before you start applying varnish, it is first better to familiarize yourself with their varieties.

The following types are considered the most popular:

water soluble;
alkyd;
polyurethane;
acrylic.

Representatives of all these groups can be used for interior finishing work: they do not emit harmful toxic fumes and are harmless to health. What are the features and performance characteristics of these products?

Water soluble

Water-based varnishes are characterized by the absence of an unpleasant odor and fairly quick complete drying. They are completely non-toxic, making it possible to paint lining indoors without the use of protective equipment.

You don't even need a respirator. Such compositions are used for treating wooden surfaces exclusively indoors.

All water-based compounds have a polyurethane or acrylic base. They can have different compositions - two-component or one-component.

The latter contains only one base, while the two-component one also contains a hardener. Therefore, the characteristics of a two-component coating are better; the coating it makes is more durable and strong.

Acrylic

These varnishes help the wood to perfectly preserve its unique natural texture. They will be an excellent choice for finishing the interior surface of premises. In addition to improving the aesthetic qualities of the treated surface, they protect it from harmful influences, including sunlight. The composition of acrylic varnishes may differ slightly, so you must carefully study the instructions.

Following it, the compositions are diluted with ether, alcohol or water. The mixture dries almost instantly after application. Surfaces treated with acrylic-containing products do not tolerate excess moisture, so if dirt appears, it is better to refrain from trying to wash it off with water. For the same reason, acrylic-based varnish is not very suitable for use, for example, in the kitchen, where humidity is usually high.

Alkyd

They have almost all the characteristics of the previous ones, but plus they are not afraid of high humidity, and even moisture itself. Therefore, the surface treated with them can be washed without fear.

The ability to wash with water is very important, especially if you have children or pets.

The alkyd varnish coating is highly durable, protecting the wood even from significant mechanical stress: it prevents scratches, chips and other damage.

Excellent as a door varnish. The disadvantages of this drug are the unpleasant odor when used, as well as the rather long time required for it to dry completely. It requires at least two days. But this drawback can be easily eliminated by adding a specially produced hardener.

Polyurethane

Polyurethane is often used for parquet

The advantages of this group of varnishes are difficult to overestimate.

They not only protect the material from aging and harmful influences, giving it a spectacular appearance.

They allow it to acquire completely unique qualities that are completely uncharacteristic of the capricious natural material:

high resistance to ultraviolet radiation;
increased resistance to moisture;
resistance to aggressive agents such as alkalis.

The remarkable characteristics of the drug determine its corresponding price.

The price for the group of polyurethane varnishes is noticeably higher than that of other groups. But you can use this varnish both inside the house and outside.

The nuances of using varnish

There are important features of the use of water-soluble varnishes, taking into account which you can obtain a more aesthetic and high-quality result.

Don’t forget to do a bio-corrosion treatment before varnishing.
Any type of varnish is best applied in at least two layers. This way you can achieve maximum strength of the protective film on the material.
When working, the varnish composition needs regular stirring. This way its structure will be more uniform, it will lay down easier and more evenly.

After the first layer has completely dried, the resulting surface is lightly sanded, after which another application is carried out.

Varnish application process

How to apply varnish correctly? The wood and lining must be well dried, only after this can you begin to decorate it. After covering the surfaces, at least five days must pass. There are no particular difficulties in the application process. The procedure is not at all difficult to perform on your own. But it is advisable to use the recommendations of experienced professionals for this.

What you will need for work:

the actual varnish composition;
container for it;
large and small brushes and rollers;
fine sandpaper;
solvent, gloves, stepladder.

The surface is well cleaned, dust and dirt are removed. If there is an old coating, it must be removed. Old varnish can be easily removed with baking soda. Areas affected by fungus or mold are treated with a disinfecting and bleaching solution. The material needs high-quality polishing. To do this, use a special grinding machine or regular sandpaper.

When all defects are removed and unevenness is smoothed, a layer of primer is applied to the surface, which fills the wood pores.

After it dries, a special antiseptic composition is applied, which helps to increase the service life of the wood. This is the so-called covering layer. After about a day, no less, you can proceed directly to varnishing the house.

It is better to use a brush made of natural bristles for this.

During use, individual hairs do not fall out of it, complicating the process and deteriorating the quality of work. The varnish must be mixed so that a homogeneous, uniform mass is obtained. Then it will lay down in a thin and even layer, and the coating will not have sloppy streaks.

After the initial varnish layer has completely dried, the surface is lightly sanded. After this, a second, final layer of varnish is applied, which may be colorless.

Wooden products and buildings need protection. For this purpose, impregnations, paints, and varnishes are used. You can give wood any color using paint, but an opaque coating will hide the design. While varnish allows you to simultaneously protect the wood and highlight its natural beauty. Choosing a varnish is a responsible matter, how not to get lost in the variety and choose exactly what you need?

Varnish is a viscous substance that consists of dissolved resins and polymers - mainly in volatile solvents. If you apply this substance to any surface, the solvent will evaporate, leaving a film - dense and shiny. Mostly varnish is applied to wood - one of the most beloved and popular building materials. The problem is that wood is vulnerable to various external influences, so a varnish coating is necessary, first of all, in order to extend the life of the wood.

Varnishes vary in gloss level and area of application: for interior or exterior work. The properties of the varnish depend on its base. For example, alkyd-urea varnishes allow you to create a durable coating, while alkyd varnishes protect the wood from moisture. Oil or petroleum-polymer varnish will help protect surfaces that bear heavy loads - floors or stairs.

The most popular varieties are parquet varnishes. For wood, acrylic and alkyd, water-based and oil-based varnishes are mainly used. Wood varnish can be purchased at any hardware store, having previously studied the assortment to choose exactly the product that you need.

A very important parameter for varnish is its shine. It all depends on the brightness of the light flux reflected from the surface.

According to the type of shine they distinguish:

High-gloss varnish for wood (the gloss of this product is more than 90%).
Gloss varnish for wood (the gloss of this product is from 80 to 90%).
Semi-gloss varnish for wood (the gloss of this product is from 40 to 50%).
Semi-matte varnish for wood (the gloss of this product is from 10 to 15%).
Matt varnish for wood (the gloss of this product is less than 10%).

Among other things, today there are tinting varnishes - thanks to innovation, with the help of coloring, you can change the shade and even color.

Wood varnish: interior work

By covering wood with varnish, you not only decorate objects, but also protect them. The varnishes themselves can emphasize the dignity of wood and deepen the texture and color, and it does not matter where you use these building materials - whether you have a wooden floor, or furniture, or walls.

Experts distinguish the following wood varnishes designed for interior use:

Parquet.
Furniture.
Universal.

Parquet varnish

The parquet board, like the parquet itself, needs a high level of protection. If they are not protected with varnish, the coating will last less than a year. It is in your best interest to choose a quality product that can provide long-term safety and simplify maintenance - parquet varnish is exactly what you need. In addition, varnished parquet looks very rich and beautiful.

Parquet varnishes have a wide range - their difference is in the base and the effect they create. After varnishing, the surface will be glossy or matte, depending on which product you choose.

When choosing parquet varnish, you need to take into account the fact which particular room you will be covering with this product. For example, if this is a bedroom, then you can buy a “simpler” varnish, because in this room there will be much less load on the floor than in the hallway or kitchen. In these rooms, it is best to use a varnish that has additional protection for the surface to which it is applied.

When choosing a varnish, you should definitely pay attention to:

Its technological properties: be sure to take into account the consistency and method of application.
Its appearance: it can be either transparent or have some kind of wood tint.
The degree of its gloss: gloss or matte, as a percentage.

Below you will learn about the types of parquet varnish.

Wood varnish: primer

These products are used exclusively for the initial coating of wood to enhance its adhesion. Primer varnishes help if you need to get an even shade, if you need to insulate the wood, or if water residue does not get on the building material.

In addition, thanks to primer varnishes, you can save money, since much less finishing coat will be needed. True, it is necessary to take a very responsible approach to the choice of primer varnish, since it must be ideally suited for the finishing (main) coating.

Wood varnish: water-soluble

Water-based varnish for wood is used most often, because its price and quality are most consistent with reality.
It contains not only water, but also emulsifiers and solvents. But it is thanks to water that it dries slowly.
Water-soluble varnishes differ from each other in composition. They either contain no solvents at all, or the percentage of this substance is about 5% or about 15%.
The main disadvantage of water-based varnishes is that they penetrate perfectly into all crevices, which creates additional floor squeaks. This is why experts advise using a primer first – also on water.
Water-based varnishes also have the disadvantage of very low wear resistance. But it is still possible to increase it - manufacturers do this by adding special additives (however, there is one more “but” - such materials are applied only when the room humidity is no more than 50%!).
In addition, waterless varnishes cannot be applied with brushes or sponges - only with a roller.
As for the advantages of waterless varnishes, they do not have a strong specific odor due to the water content and are absolutely non-flammable.

Wood varnish: polyurethane

Waterless or polyurethane varnishes have a high level of protection - they tend to withstand high loads.
In addition, these varnishes have very high adhesive properties.
Polyurethane varnishes must be mixed thoroughly, as they are either one-component or two-component.
As for the base, a solvent is used to create these products, as well as either acrylic or urethane.
Waterless varnish dries very quickly - much faster than water-based varnish.
During application or while it is drying, the varnish must be protected - not even a drop of water should fall on it.
These varnishes do not require priming the wood before application.
Polyurethane varnishes are quite elastic.
Waterless varnishes do not require a special room microclimate.
During operation they are not afraid of water.
Currently, polyurethane varnish is the best product for applying to the floor, even if there is a large load on the coating in the room.

Wood varnish: alkyd

The basis for alkyd varnishes is natural raw materials - oil resins. Most often, linseed and wood oils are used, so such varnishes penetrate deeply into the wood and cover the entire surface with high quality.
Alkyd varnishes are quite toxic, since they contain a component such as white spirit in high concentrations.
Thanks to alkyd varnishes, the structure of the wood stands out more clearly.
Alkyd varnishes can enhance the natural beauty of wood.
Oil-based varnishes tolerate various mechanical loads well, including temperature changes and humidity.
Alkyd varnishes do not stick into all the cracks during application and do not glue boards or other objects together.
It is necessary to dry alkyd varnish at a low temperature, since it is very sensitive to high temperatures.
Alkyd varnishes have low wear resistance.
These varnishes are applied in a thin layer, this must be strictly monitored.

Wood varnish: formaldehyde

The basis of these varnishes is formaldehyde resins, which are dangerous to human health, so the substance must be applied in a respirator.
Such varnishes are the most wear-resistant of all other types of varnishes.
Formaldehyde varnishes can be applied immediately as a finishing agent - without a primer.
Formaldehyde varnishes have very good adhesion to wood.
Formaldehyde-based varnishes cope well with temperature changes and any humidity.
Formaldehyde varnishes can be applied with any tool: roller, brush, etc.
Formaldehyde varnishes have a very pungent odor - this is their main drawback.
The consistency of formaldehyde varnish is very thick - it is highly adhesive, so it can glue dies together.

Is it difficult to choose a varnish for a room? Contact a specialist who can advise you on this.

But many people recommend this algorithm:

For the bedroom or children's rooms - water soluble.
For the living room, office or balcony - alkyd.
For the corridor, hallway or kitchen - formaldehyde.

Wood varnish: furniture

Wooden furniture is very expensive, so experts advise paying special attention to protecting these items - for example, you need to choose a good varnish.

Furniture varnish will not only create a protective layer, but will also emphasize the elegance and structure of the wood.

Today there are such furniture products:

Oil varnish for wood.
Alcohol varnish for wood.
Alkyd varnish for wood.
Acrylic varnish for wood.
Polyurethane varnish for wood.

The most popular and popular last type is polyurethane. It is wear-resistant and impact-resistant. In addition, this varnish can be used for both interior and exterior use.

Today, varnish manufacturers add various additional substances to polyurethane, for example, antioxidants or ultraviolet absorbers. Due to its high performance, this product is used not only for varnishing furniture, but also for a wide variety of surfaces.

The advantage of polyurethane varnishes is that they are harmless. In addition, they are environmentally friendly. And also - they are really transparent and do not tend to turn yellow over time.

Wood varnish: exterior work

To protect wood that is outdoors and is exposed to various mechanical impacts every day, it is necessary to use a special varnish for outdoor use. This product has enhanced protective properties and is able to protect wood from environmental aggression, taking into account all the individual characteristics of the tree.

Exterior varnish is intended for painting:

facades;
garden furniture;
gazebos;
fences;
wooden flooring;
terraces;
beams and joists;
log buildings (including their crowns).

Varnish for external use perfectly protects wood from moisture and precipitation. Wooden objects will serve you for a very long time - it will be enough to apply a protective layer of varnish on them.

And, despite the fact that wood varnish for exterior use has a higher price than one created for interior use, it is still a savings, because thanks to such protection you will definitely extend the life of wooden products!

To varnish wooden objects, you must follow some simple rules:

Sand the wooden surface.
If there is paint or varnish on the wood, these layers must be removed. This is best done with sandpaper (minimum 100R).
If you paint with tinting varnish, the wood can be covered with stain.
After sanding, the dust must be thoroughly swept away.
Now the primer varnish is applied - this way you will protect the coating from bubbles and all kinds of visual defects.
Applying varnish.

Varnish can be applied in several ways, the most common being with a roller or brush.

Brush. Used when applying varnish to hard-to-reach places and when painting small elements and parts. To avoid leaving streaks, use a brush that has “fluff” at the ends of the bristles.
Roller. Used on large surfaces. When choosing a roller, keep in mind that the pile should not be longer than 5 mm.
Spraying. The best option is when the varnish is applied using a compressor and a spray gun. This is the best method, as it is economical and allows you to paint even very hard-to-reach places. Thanks to spraying, the coloring will be of very high quality.

Before applying the varnish, mix it thoroughly, especially if the product you choose is a two-component one. This is necessary for the durability of the varnish coating.

If you are going to apply varnish several times to the surface, be sure to sandpaper (220R) between layers and remove dust after that.

The layers of varnish depend on what you are specifically varnishing: if it is a floor, then three layers are needed, and if it is furniture, then two layers will be enough (this calculation also includes the primer).

After you have varnished the surface, you need to wait for it to dry completely. There is no single advice here, since different manufacturers have different advice - the period is indicated on the can, so carefully study everything that is written on the packaging.

And the wood should be given strength and protected from the effects of negative factors by means of a varnish coating. From this article you will learn which colors of wood varnish are most often used for this purpose.

Features of wood varnishes

Varnishes are viscous solutions that are used to treat wooden surfaces in order to obtain a protective film. Surfaces coated with them acquire a rich or light shine.

The first use of varnish was in the 12th century by the German monk Theophilus. The secret of creating the varnish was kept in the strictest confidence, only after years of research it became clear that the monk’s recipe was based on alcohol. In the 15th century, oil-based varnishes began to be produced. England is considered their homeland.

Mass production of wood varnishes began only in the 19th century. In 1874, the Russian Osovetsky plant launched the production of oil varnishes of excellent quality. Subsequently, other varieties began to be produced.

Most often, wooden surfaces are coated with varnish. The strength and beauty of wood is lost quite quickly under the influence of external factors, and varnish treatment allows you to extend its service life.

Main types of wood varnishes

Oil varnishes initially included only solutions of natural resins. Now they consist of artificial resins and modified natural oils with the addition of solvents and driers. The use of artificial analogues has made it possible to significantly reduce production costs, and therefore the cost of oil paint for wood has become much more affordable. After applying oil varnish to the treated surface of the wood, a durable film of a slightly yellowish color is formed. Oil varnishes are mainly used for finishing floors and performing indoor work.

For the production of alkyd varnishes on wood, glypthal and pentaphthalic synthetic resins are used, to which driers are added. Despite the fact that these varnishes are sometimes classified as oil-based (since they use synthetic oils as a solvent), their performance characteristics are at a higher level compared to varnishes of the first group.
You can give the surface high strength and shine using alcohol varnishes and polishes. Such coatings are easy to polish, but they do not provide very high protection against moisture. Alcohol varnishes and polishes, for the production of which natural resins are used, are now produced in small batches. They are mainly used in the manufacturing process of musical instruments.

Alkyd-urea varnishes consist of solutions of alkyd and amino-formaldehyde resins. To dry such products in air at normal temperatures, it is necessary to add acidic hardeners to their composition. They are added to varnishes before surface treatment begins.

After the hardener is introduced, the varnishes have a limited period of use (depending on the properties of the hardener, it can range from 3-4 hours to 1-2 days). The film formed by such wood products is very hard and wear-resistant. They are used to process parquet, furniture and other interior items used indoors.

To make nitrocellulose varnish, cellulose nitrate is mixed with various organic solvents. To adjust the properties of this product, resins are added to the composition.

Nitrocellulose varnish creates a hard and durable film, transparent, without any tint. It is used to cover wooden elements and products intended for indoor use.

Polyester varnishes contain a large number of different components. Its use requires great precision of application. Coating with polyester varnish practically does not shrink; the thick film formed after its application has a high degree of resistance to such negative factors as water and various reagents.
For the production of acrylic varnishes, solutions of polyacrylates and organic solvents are used. The film obtained by treating wood with this product has low abrasion resistance. Due to their environmental friendliness, as well as a large selection of wood varnish colors, they are recommended for use in children's rooms.

Exceptionally high mechanical strength and wear resistance are inherent in polyurethane varnish. They cover floors in palaces and museums, and musical instruments. Its use requires strict compliance with the requirements specified in the instructions. This is the most expensive product for wood, the cost of which is justified by its high performance characteristics.
Not so long ago they began to produce water-based polyurethane varnishes. They combine the advantages of acrylic and polyurethane varnishes, such as high abrasion resistance and environmental friendliness. And if you use a product with strengthening additives, its service life will increase significantly.

Colors of wood varnishes for interior work

The modern market offers a wide selection of wood varnish colors. Before you go shopping for paint and varnish material, you need to decide where it will be used. Surfaces and products indoors are treated with products for interior work.

If you need to cover exterior facades or objects used outdoors with it, buy wood varnish for outdoor work. When using varnish intended for indoor work outdoors, the treated surface can fade or crack very quickly.

Below are the options for wood varnishes (colors in the photo) for interior work.

The main task of the paint and varnish material is to create a durable coating and give it a certain color.

Below are some of the benefits of colored wood varnishes:

Provide protection from external factors.
Perform a decorative function.
Increases the service life of wooden products.

Using wood varnishes of different colors, you can create glossy or matte surfaces. Basically, this indicator is indicated by the manufacturer on the packaging. Semi-gloss or semi-matte products are also available on the market. Using high-gloss varnish, you can give a wooden product a bright shine.

Most often, wood is treated with a transparent product. It is able to emphasize the grain of the wood, giving it clarity and expressiveness. Using wood varnishes of different colors you can radically change the shade of a wooden product.

“Mahogany” and “walnut” are the most popular colors of wood varnishes. With their help, objects are visually enlarged. If we talk about dark shades, then most often they resort to a black product, which adds sophistication and luxury to the products. White wood varnish is also unique and effective.

When choosing wood varnish colors, do not forget that they have a large number of different shades.

For example, when covering a parquet board with walnut wood varnish, you can achieve several different color effects. Floors can be beige, red, black or dark brown.

Tinting compounds are preferred by owners of private houses. They are used for processing doors, furniture, and parquet. Thanks to them, the wood is given not only a beautiful appearance, but also increased resistance to mechanical stress, the formation of blue stains, fungus and mold.

Wood varnish for exterior use and its colors

Water-based varnishes are in greatest demand today.

Among the advantages of this group are the following:

To make the compositions, an aqueous dispersion with a small addition of solvent is used. This allows you to work in a room where there are people, since there is virtually no smell or fumes harmful to human health.
The colors of water-based wood varnishes for outdoor use have a wide palette, which is their main advantage. You can choose any shade that matches other decorative elements. In addition, having achieved the desired tone, you will not hide the beauty of the wood structure.

The following structures and elements are treated with wood varnishes of different colors for exterior use:

building facades;
furniture parts;
gazebos;
Walling;
wooden flooring;
terrace designs;
beams;
log cabins

To paint large areas, you can use aerosol wood varnish in a can or spray. This type of paint and varnish material includes bitumen varnish, which protects wooden surfaces from rotting, mold and mildew.

How to choose the right varnish for wood

When choosing a wood varnish, answer the following questions:

What characteristics should the wood surface have after you varnish it?
Do you have experience working with paints and varnishes?
What room or product are you going to process?
How much money are you willing to pay for finishing wooden surfaces?

Your personal preferences play a big role in your choice. For some, environmental safety is important, so they opt for water-based varnishes. They do not smell and are absolutely safe for human health. They often cover furniture for children's rooms. However, they are practically not in demand among professional furniture makers, since the surface becomes matte after processing.

Due to their ease of use and affordable price, alkyd varnishes are suitable for beginners. They can be easily washed off with white spirit if mistakes were made during their application. Professionals mainly use polyurethane types of products. With their help, a more durable and strong film is created. To apply the product, use a spray bottle. Furniture oils are mainly intended for connoisseurs and connoisseurs. They are applied manually with a swab. The surfaces they treat look very stylish.

An important issue is the choice of wood varnish color. The professional can tell you whether to keep the natural color of the wood or give it a new tone. Do not forget that wood coated with colorless varnish still acquires a yellowish tint. If you find it difficult to choose the color of wood varnish, contact a specialist at a hardware store.

How to calculate wood varnish consumption

Simple calculations will help you determine the number of cans of varnish needed to paint a certain area.

First of all, pay attention to the criteria that play a significant role in varnish consumption:

Wood surface. Wood with fine pores requires less varnish than wood with deep pores. Thus, the consumption of paint for beech or pine surfaces will be less than for oak or ash.
Wood sanding quality. If the surface of the wood is carefully sanded, the varnish consumption will be less. The product can be processed with high quality using sandpaper with P100 grain. If it is necessary to apply a second layer of varnish, use sandpaper with P220 grain.

Viscosity. The consumption of thick varnish is always greater. To reduce it, you can apply the first two layers of varnish, which is diluted with a solvent. A small amount of water can be added to a water-based product for a lower viscosity.
Method of application. Minimum consumption can be achieved using spraying. Painting with a brush or roller significantly increases the consumption of varnish.

On average, 100-125 ml of varnish is needed to treat 1 m² of surface. When applying the second layer, less material is needed, approximately 80-100 ml per 1 m². However, do not forget about the factors described above. For a more accurate calculation, you can buy a can of wood varnish of the desired color, treat the surface, and then measure its area. In this case, the calculation will be very accurate.

How to varnish wood

Varnishing a wooden surface requires compliance with the application technology:

The old surface is treated with sandpaper.
Then the product is polished and dust is removed from it. Remember that the consumption of wood varnish depends on the quality of sanding, regardless of its color.
When using tinting varnish, you need to use a stain.
Then the primer is applied (in compliance with all the rules for its use).
Finally, the surface is coated with wood varnish of the chosen color using a brush, roller or spray.

It is most convenient to apply the varnish with a roller. Use the brush to treat hard-to-reach areas. The brushes, which have a slight fluff at the end, do not leave marks on the surface.

Using a sprayer you can treat large surfaces in a short time.

To finish wooden furniture, you will need to apply two layers of varnish, and to treat the floor - three.

The facade of a wooden house is under constant influence of adverse weather environmental factors. Therefore, the key points in choosing a varnish to cover the external walls of a house are not only the aesthetic characteristics of the material, but its protective properties. Varnish for the wooden facade of a house must provide protection from any natural factors: moisture, pests, ultraviolet radiation. Only in this case can you be sure that the coating will last for many years. Today you can find a wide range of varnishes, but not all of them can provide reliable protection for the facade. In this article we will talk about how to choose varnish for a wooden house.

There are quite a lot of products available on the modern market for exterior finishing of a wooden house. , which will completely hide the structure of the wood, is possible, but only varnish allows you to preserve and emphasize the natural beauty of the wood. Varnish forms a dense elastic film on a wooden surface, which decorates and at the same time protects the wood.

An important criterion for choosing a varnish is its operating conditions. In this case, it will be applied to the facade of the building, which is located in the open air.

There are special requirements for products intended for exterior finishing. Varnish for exterior finishing of a log house must protect the wood from mechanical damage, negative natural and biological factors, and also have good decorative characteristics.

Requirements for paint and varnish materials for facade finishing:

Wear resistance. This indicator is especially important when varnishing external horizontal surfaces: terraces and steps. In this case, it is necessary to choose a composition with a high degree of resistance to wear and mechanical damage. A varnish with average wear resistance is suitable for covering the walls of a wooden house.
UV resistance. Ultraviolet radiation is one of the main causes of fading and rapid wear of the coating. It is necessary to varnish the facade with products containing special components that increase resistance to direct exposure to the sun.
Waterproof. The main enemy of wood is moisture, under the influence of which the wood begins to rot and fungus and mold appear on the surface. Therefore, it is very important that the varnish coating creates a protective layer on the surface that repels water.
Protection from insects. Wood is a breeding ground for various microorganisms and beetles, which, settling in its structure, destroy the wood from the inside. It is desirable that the varnish contains substances that protect the wood from pests.

There are several types of varnishes that can be used to coat the external surfaces of a wooden house. The choice of a specific product depends on the climatic conditions of the area, the lumber used for construction, and the characteristics of the paint and varnish product.

To varnish old, previously painted wooden surfaces, it is necessary to select a varnish with the same base. For example, you cannot apply alkyd varnish to a surface coated with a water-soluble composition. Wood, completely cleared of old coating and well sanded, can be painted with any means.

When choosing a varnish, its decorative characteristics are also taken into account. The varnishes have a wide palette of colors, which allows you to choose the desired shade in accordance with the overall style of the facade. You can choose a glossy or matte varnish, which forms a transparent or translucent film on the surface.

These varnishes are based on artificial or natural heat-treated oils. The products also contain resins of natural or synthetic origin.

Depending on the percentage of oil, formulations are divided into fatty, semi-fat and lean. Only varnishes with a high oil content, belonging to the group of fatty products, are intended for external use. A composition with a higher oil content is more resistant to atmospheric conditions.

Oil-based varnishes have good protective properties; they form a water-repellent film on the surface, which demonstrates high light resistance. Varnishes of this type take quite a long time to dry (from 12 hours to three days), so it is advisable to carry out work in consistently warm and dry weather. It should also be taken into account that oil varnishes give the wood an ocher tint.

Judging by the name, it is clear that the paint and varnish product is intended for painting yachts. But due to its excellent performance characteristics, this varnish is very often used for varnishing the external surfaces of wooden houses.

Yacht varnish is exceptionally reliable and durable. Such indicators were achieved by including toxic components in its composition - toluene and xylene, which are very harmful to health and can cause poisoning. Therefore, it is intended for outdoor use only.

But, despite this, it is often used to paint the floor and other surfaces inside the house, which is absolutely forbidden to do, since even after many years the varnish coating will release harmful substances into the atmosphere.

The use of yacht varnish to coat the outside of a log house, on the contrary, is welcome. The varnish coating provides reliable protection of the external walls of the log house from various atmospheric influences, and also gives the wood a noble appearance.

Alkyd varnish

The varnish is made on the basis of alkyd resin and also contains various oils and a solvent. The product creates a durable and strong coating that is resistant to temperature changes, humidity and mechanical stress. The composition has good water-repellent properties and protects wood from the formation of fungus, mold and insects.

The product takes more than a day to dry and produces an unpleasant odor. Excessive application of varnish may cause the finish to wrinkle.

Polyurethane varnish

The varnish intended for painting external logs and beams is made on the basis of organic solvents. It penetrates deeply into the wood, forming a protective wear-resistant layer on it. The varnish is resistant to ultraviolet radiation, mechanical damage, and tolerates temperature changes.

The varnish can be one-component or two-component. In the first case, the product is sold ready for application. In the second, it is necessary to add a hardener to the composition before work. A two-component product is better suited for painting large areas.

Water-soluble varnishes

This type of paint and varnish is produced on a water basis. Varnishes of this type are safe for humans and do not emit harmful substances or odors. They come in a wide variety of colors. The product provides complete protection of the surface from microorganisms, mold and fungi.

The composition dries in about a day, but it takes about two weeks for the final formation of the protective film. However, water-soluble varnishes are not able to provide such reliable surface protection as organic compounds. The coating requires regular updating.

The varnish must be applied to dry wood. If it rained the day before work, it is better to postpone varnishing and wait until the wood is completely dry. The moisture content of coniferous wood during painting should not exceed 15%; for hardwood this figure is 12%.

Regardless of the means used to varnish the facade, varnishing the timber outside the house must be done in calm and dry weather. The street temperature should be at least 10 degrees, and the optimal values are 15-25 degrees with a humidity of about 80%.

Before varnishing, the surface must be carefully prepared:

clean the facade from dirt and dust;
remove the previous paintwork;
sand the wood well;
apply two layers of antiseptic on the walls and 3-4 layers on the ends of the timber to protect the wood from rotting and microorganisms;
treat the house with fire retardants to prevent fire;
prime the surface.

When diluting varnish, it is necessary to take into account its type. As a rule, paintwork materials are mixed with a solvent. Only water can be added to acrylic products. Yacht varnish is generally not recommended to be diluted.

It is more convenient to apply varnish to the facade of a building with a spray bottle, in this case the composition will evenly cover the surface. It is better to treat edges and hard-to-reach areas with a brush with mixed bristles. For oil composition it is recommended to use a natural brush.

Before varnishing the lining outside the house, you should test it for adhesion, decorative characteristics and color of the future coating. To do this, apply the product to a small, inconspicuous area. After the composition has dried, try removing it with a spatula. If the coating is difficult to remove, this indicates good adhesion of the materials. If the spatula leaves deep marks, the surface needs to be primed again.

To get a beautiful and durable coating, you need to apply at least two layers of varnish. If porous wood is painted, the surface is varnished at least three times. After each layer has dried, it is recommended to perform intermediate sanding with fine-grained sandpaper.

There are many. When deciding which wood varnish is best to choose, take into account the purpose of the materials being processed and the conditions in which they will be used.

Alkyd varnishes

Wood varnishes with alkyd compounds are used for treating wood indoors and outdoors. In terms of durability, this type of varnish is one of the best. The wood coating is hard and reliably protects the wood from moisture. The varnish is resistant to ultraviolet rays. There are also some minor drawbacks: the varnish takes a long time to dry, at least three days. Additional additives in alkyd varnishes can reduce drying time to up to a day.

Another type of alkyd varnish is products with urethane group additives. Such varnishes dry much faster - up to 12 hours, while the strength characteristics of the coating itself increase significantly.

Oil varnishes

Oil-based varnishes are also often used for indoor wood finishing. Such products are presented in several shades: from pale yellow to intense brown. The final appearance of the processed product will depend on the chosen shade of varnish.

The composition of this type of varnish varies in terms of fat content. Fatty and medium-fat varnishes apply easily and well to the surface and, in addition to the decorative effect, serve as protection for the surface. Varnishes with a low fat content, up to 55%, are used exclusively for the aesthetic treatment of wood.

Water-based acrylic varnishes

Choosing acrylic varnish for wood is for environmentally friendly people. The material is safe from this point of view, it has no odor, and gives the treated wood fire-resistant properties. These varnishes are used for finishing interiors and exteriors. They retain the texture of the wood, but do not give off a yellowish tint like other types of varnishes. Usually, stores offer a whole line of varnishes that have varying degrees of gloss. These products are not recommended for rooms with high traffic and constant, let alone high, humidity. Ultraviolet rays do not have a significant effect on the varnish. Acrylic varnish takes a long time to dry; it takes about 2 weeks for the film to completely form.

Nitro polishes

This type of varnish is used for different types of wood, but mainly for indoor work, since there is no resistance to ultraviolet rays. Nitrovarnishes are also not used in damp rooms. In other cases, they are good because they quickly penetrate the wood, provide reliable protection and dry very quickly, within just a couple of hours. It is necessary to apply nitrovarnish in a respirator, since it contains solvents that have a high degree of toxicity.

Polyurethane varnishes

Very often, varnishes with a polyurethane composition are used for exterior finishing. The most famous type of this varnish is yacht varnish. It is resistant to moisture, wear-resistant, and can withstand high traffic. The surface of wood after coating with polyurethane varnish is usually glossy. This product is also often used to treat furniture, floor coverings, and even small interior items.

For exterior woodwork, a special frost-resistant varnish must be used. This composition can be used for decoration and protection of wooden products that are located outdoors.

Exterior varnish will extend the life of wooden surfaces

In winter, wooden structures can be significantly affected by negative temperatures, which impair the performance properties of the surface.

For example, if moisture penetrates into the structure of a tree in winter, then when it freezes, the liquid can expand and lead to the destruction of the coating. Therefore, any frost-resistant varnish used for exterior work must have pronounced water-repellent properties.

Today, frost-resistant paint and varnish compositions are actively used for painting the following wooden surfaces:
roof elements;
steps made of wood;
porch;
outdoor wood furniture;
terrace boards;
bath walls;

wooden sculptures.

All these surfaces need not only protection from moisture, ultraviolet radiation, mold and fungi, but also from exposure to extremely low temperatures.

Varieties of frost-resistant compounds

Today the choice of varnishes is large, the main thing is not to make a mistake, and for this you need to know a number of criteria, which are given below

Today there is a large selection of paints and varnishes for exterior use. Basically, all of them do not affect the natural wood texture and do not change the shade of the surface. Modern materials with a frost-resistant effect can have an oil, water and organic base. Any of these compositions forms an elastic film after drying, which increases the surface’s resistance to mechanical stress at low temperatures.

In addition, paint and varnish material for external use contains various chemical additives that protect the coating from fungal attack, ultraviolet radiation, cracking and discoloration.

Key characteristics on which the effectiveness of frost-resistant coating depends:
water-repellent properties;
permeability to vaporous substances;
resistance to mechanical deformation;
resistance to ultraviolet rays;

impact resistance.

The main types of frost-resistant varnishes, depending on the composition:
solvent-based paints and varnishes;
water-based varnishes;
compositions based on alkyd-urethane;
oil solutions;

yacht paint and varnish compositions.

Yacht varnish is frost-resistant, wear-resistant and highly durable

Types depending on purpose:
universal formulations;
varnishes for wooden furniture;
glossy paint and varnish coatings;

Popular paint and varnish compositions are solvent-based coatings. The composition hardens after complete evaporation of the solvent. As a result, a high-strength film is formed. This frost-resistant varnish is ideal for outdoor use, as it is resistant to abrasion and the chemical effects of detergents. However, solvent-based coatings can change the color of the wood surface, adding yellow tones.

Frost-resistant varnish with a water-soluble base is not as resistant to abrasion. At the same time, such material is considered more environmentally friendly. In addition, water-based material dries faster than all others.

The most durable varnish is considered to be one created on an alkyd-polyurethane base. It has excellent performance characteristics. A feature of oil-based paints and varnishes based on natural resins is that they can change the color of a country floor or other wooden surface, making it darker.

Today, woodworking has become popular for outdoor work. This paint and varnish material has all the necessary qualities in terms of elasticity and durability that are required for such compositions. It has increased frost resistance, as well as pronounced water-repellent and dirt-repellent characteristics. In addition, frost-resistant varnish of this type is applied without any problems and does not leave smudges.

Application method

Frost-resistant varnish should only be used after the surface has been coated with impregnation. It is recommended to apply the paintwork in 2 or 3 layers. All work must be carried out at a positive temperature. The paint and varnish material can be applied using a regular brush, roller or pneumatic sprayer. If you are going to work with a sprayer, then it is best to dilute the paint and varnish composition. The solvent used must match the composition of the varnish.

Before applying each subsequent layer, the wooden surface must be sanded to improve its adhesion. At the same time, the next layer should be applied no earlier than four hours after painting.

Thus, frost-resistant varnish is very effective for outdoor woodwork. It allows you to protect the wooden surface from the negative effects of low temperatures and other adverse environmental influences.
