The surface must be beautiful: how to choose a varnish for wood and not make a mistake. Choosing the best varnish for wood for outdoor and indoor work The most resistant varnish for wood

Wood remains a popular building material. Aesthetics, practicality, versatility, good thermal insulation properties are only part of the advantages, but the main drawback is low resistance to moisture. You can correct the situation if you use wood varnish for outdoor work. Manufacturers produce different types of coatings, which differ in technical properties.

Characteristics of varnishes for outdoor use

The service life of wooden surfaces and products is affected by atmospheric phenomena, temperature changes, and sunlight. The varnish and varnish covering allows to provide reliable protection to wood if the varnish is picked up correctly.

When choosing a LKM, it is important to pay attention to the following characteristics:

• Moisture resistance. From moisture and water, the tree begins to rot and collapse. The varnish must create a durable moisture-resistant layer on the surface that will not allow moisture to penetrate into the wood.
• Frost resistance. The property is determined by the waterproof ability. The coating should easily endure sub-zero temperatures without damage or deformation. If the material, after drying, does not have sufficient water-repellent properties, then water will penetrate into microcracks. When frozen, it will increase in volume, damaging the coating.
• Wear resistance. There are varnishes with different wear resistance. For terraces, piers, stairs and other places with high loads, you should choose compositions with good wear resistance. For fences, facades, vertical surfaces and products that are not subject to heavy loads, paintwork materials with medium wear resistance are suitable.
• UV resistant. The composition should contain additives that provide protection from ultraviolet rays. Otherwise, from constant exposure to the sun, the coating will quickly fade.
• Strength and resistance to mechanical damage. Wood is considered a soft material and needs to be reliably protected from mechanical damage. The lacquer must be durable.
• Drying time. The indicator can be from 2-4 hours to several days, depending on whether a quick-drying or regular composition is used. Drying time depends on environmental conditions.
• Resistance to temperature changes. The coating must be strong, but at the same time elastic, in order to be easily deformed by temperature changes without the appearance of cracks and other defects.

Types of varnishes for wood for outdoor use

Depending on the components in the composition, several types of varnishes are distinguished, which differ in properties and characteristics from each other.

Oil based varnishes

The main component of such paints and varnishes is refined oil. The composition includes synthetic or natural resins. For the most part, they provide reliable protection to the tree. Colorless oil-based coatings are rarely found on sale. They are presented in a large range of colors - from light yellow to dark brown.

The main advantages include:

• environmental safety;
• good resistance to moisture;
• high coating strength;
• availability.

And although the varnish forms a durable coating, it does not interfere with air exchange. The main disadvantage is a long drying time (1-3 days). It is recommended to apply coatings in sunny weather at temperatures above +10 degrees. Oil formulations are often thick, making them difficult to apply with a brush.

Polyurethane varnishes

Depending on the composition, they can be one-component and two-component. In the second case, a hardener is additionally used. The polyurethane-based paint and varnish material is versatile, as it is used for painting facades, fences, terraces, etc. It forms a durable coating on the surface with good elasticity (does not deform under temperature changes).

Facade varnish based on polyurethane has the following advantages:

• coating strength, resistance to mechanical stress;
• water-repellent properties;
• resistance to ultraviolet, chemicals;
• surface adhesion;
• fast drying.

It is allowed to paint only dry wooden surfaces. Upon contact with water, the composition loses its performance properties.

The main disadvantage is the higher cost compared to other types of coatings.

Alkyd varnishes

The main raw materials for production are glyphthalic and pentaphthalic resins. Solvent or white spirit is used as a solvent. Sometimes manufacturers add special substances that speed up the drying process.

The material forms a film resistant to moisture and ultraviolet on the surface. It tolerates changes in temperature and humidity, atmospheric phenomena. It is usually used for painting surfaces that are not amenable to heavy loads, as it has low wear resistance.

Main advantages:

• decorative (emphasizes the structure of the tree);
• resistance to mold and fungi;
• affordable price;
• ease of application.

The main disadvantage is a long drying time (24-72 hours). When dried, the varnish exhausts a sharp unpleasant odor. To feel this disadvantage less, it is worth choosing a composition with special additives.

Water-based varnishes

Acrylic varnish is usually produced on the basis of an aqueous dispersion. The composition may contain a solvent, but its content does not exceed 15%. The main advantage of paintwork materials is environmental safety. It has no unpleasant odor and is non-toxic. It can be transparent or colored, well emphasizes the structure of the tree. Surfaces painted with acrylic lacquer are reliably protected from moisture, mold, and fungi. They are used for surfaces that are not subjected to heavy loads, since the wear resistance is weak.

Manufacturers produce two-component water-based varnishes. In addition to acrylic, they contain polyurethane. In this regard, they have the best technical characteristics. They form a durable coating that is resistant to mechanical stress, UV and moisture.

Yacht compositions

Frost-resistant and moisture-resistant yacht varnish forms a durable coating on the surface. Initially, it was created for painting yachts and ships, so the main focus was on excellent performance and durability. Over time, the scope has expanded.

Even with constant exposure to atmospheric phenomena, temperature changes and other negative factors, the coating can last for a long time. An important advantage is versatility (can be used for horizontal and vertical surfaces). The disadvantage is high toxicity.

Step by step instructions for applying varnish

You can varnish wooden surfaces yourself if you have general information about the features of applying paintwork materials. For work, you will need an available tool. It is not necessary to have special skills.

Varnish consumption

• type of wood (the porous surface absorbs varnish more);
• material viscosity;
• quality of preparation of the painted surface;
• application method.

When applying the first layer, the consumption of varnish is usually more, then it diverges more economically. If a spray gun is used, less material is required than when painting with a brush or roller.

Tool selection

The selection of the necessary tools depends on the method of applying the material. The spray gun is usually used by professionals. If you do not have this professional equipment, you can get by with hand tools. Wood can be varnished with a brush or roller. Brushes will need different widths depending on the characteristics of the surface to be painted. The roller is convenient to use for covering large flat surfaces - terraces, fences, etc.

It is important to take care of personal protection. Wear gloves and a respirator while working.

Surface preparation

At the preparatory stage, the following steps should be performed:

1. Sand the surface thoroughly. Use sandpaper of different grits for this. Work can be done manually or using grinders.
2. Remove all dust with a vacuum cleaner.
3. Proceed to the next step if the surface is clean and dry.

If a vacuum cleaner is not available, the dust is brushed off and then the entire surface is wiped with a slightly damp cloth and allowed to dry completely before applying primer or varnish.

Primer

The primer composition is used to improve adhesion, leveling the surface (eliminating minor irregularities), and improving the performance of the varnish coating.

The primer is applied to the cleaned and prepared surface with a brush. The composition should be selected depending on the type of coatings. The primer should be applied in a thin layer. When dry, sand and re-primer. The number of layers depends on the general condition of the wood and the desired effect.

Applying varnish

Before application, waterproof wood varnish must be mixed well so that the contents of the can become a homogeneous mixture. If the composition is too thick, it is diluted with a solvent to the desired consistency. Apply LKM should be from top to bottom in a thin layer. Make sure the coverage is even. If streaks appear, they must be removed immediately.

When the first layer dries, it is sanded with fine sandpaper, and then re-opened. The varnish is applied in at least 3 layers, sometimes more. Each layer must be sanded. The final coat is sometimes polished to achieve a beautiful sheen and smooth surface.

If you choose and apply the varnish on a wooden surface correctly, you can reliably protect it from atmospheric phenomena and other factors. When choosing, you should focus on the operating conditions and take into account the cost.

Often, a special wood material is used as interior decoration. Lining is a natural, environmentally friendly material. It has great features and also looks great. Often it is used for finishing verandas, and simple ones. Therefore, special requirements are imposed on the material.

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

the surface is varnished, which ensures the safety of the material and its properties.

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

What are the benefits of a wood texture that has been processed?

• Prevention of appearance and rot.
• Resistance to various mechanical damage.
• Protection from sun exposure.
• Increased fire resistance
• Aesthetics.

Often, lining during installation is processed with various special-purpose compositions: drying oil, antiseptic, stain. The original appearance of the material changes somewhat. Coating with varnish on top refreshes it and ennobles it.

Choosing the Right Tool

Lacquer types

How and with what to cover the tree?

Before starting work on applying varnish, it is first best 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 funds?

water soluble

water soluble

For varnishes made on a water basis, the absence of an unpleasant odor is characteristic and a fairly quick complete drying. They are completely non-toxic, thanks to which the coloring of the lining in the room can be done without the use of protective agents.

You don't even need a respirator. Use similar compositions for the treatment of wooden surfaces exclusively.

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

The latter contains only one base in its composition, the two-component one, in addition to it, also has a hardener. Therefore, the characteristics of the two-component differ in better performance, the coating made by it is more durable and durable.

Acrylic

These varnishes help the wood perfectly preserve the unique natural texture. They will be an excellent choice for finishing the surface of the premises. In addition to improving the aesthetic qualities of the treated surface, they protect it from harmful influences, including from sunlight. The composition of acrylic varnishes may vary slightly, so you need to 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 products do not tolerate excess moisture, therefore, in case of contamination, 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 possibility of washing with water is very relevant, especially in the presence of children or pets.

The alkyd lacquer coating is characterized by increased strength, protecting the tree even from significant mechanical influences.: It prevents scratches, chips and other damage.

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

Polyurethane

Polyurethane is often used for parquet

The advantages of this group of varnishes can hardly be overestimated.

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

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

• high resistance to UV exposure;
• increased resistance to moisture;
• resistance to the action of aggressive agents such as alkalis.

The remarkable characteristics of the drug determine its corresponding cost.

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

The nuances of using varnish

There are important features of the use of water-soluble varnishes, given which you can get a more aesthetic and high-quality result.

• Do not forget to do a biocorrosion treatment before varnishing.
• Any type of varnish is best applied in at least two coats. So you can achieve maximum strength of the protective film on the material.
• When working, the varnish composition needs regular mixing. So its structure will be more homogeneous, it will be easier and smoother to lie down.

finishing . After facing the surfaces, at least five days must pass. There are no special 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 is required for work:

• actual lacquer composition;
• capacity 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 soda. The affected areas are treated with a disinfecting and bleaching solution. The material needs high-quality grinding. To do this, use a special grinder or ordinary sandpaper.

When all defects are removed and the irregularities are smoothed out, a layer of primer is applied to the surface, which fills the wood pores. After it dries, a special composition is applied - which helps to increase the 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 worsening the quality of work. The varnish should be stirred so that a homogeneous, uniform mass is obtained. Then it will lie down in a thin and even layer, and the coating will not have sloppy streaks.

After the final drying of the initial varnish layer, the surface is lightly sanded. After that, a second, final layer of varnish is applied, which may be colorless.

Used to impart aesthetic and protective properties to surfaces. They are solutions of synthetic or natural resins in special solvents, which can be ethanol, acetone, drying oil, water, etc. In this article, we will look at how to choose a varnish for floors, furniture, facades and other surfaces.

What varnish is better to use for wood

Before choosing a varnish for a wooden floor or other surfaces, it is worth studying the advantages and disadvantages of varnish varieties.

1. Water-based varnishes are absolutely safe for human health, do not provoke respiratory diseases, are odorless, dry quickly, but are easily susceptible to destructive external influences.
2. Alkyd varnishes are made on the basis of glyptal and pentaphthalic resins. Resistant to pollution, aggressive chemical environments, as well as abrasion and deformation. After application, they dry quickly, have a smell.
3. Bituminous varnishes allow you to protect wooden products from the processes of decay and the formation of microorganisms, they are also used for hydro- and electrical insulation of metals. Dries quickly, has a smell. Among the shortcomings, there is a low resistance to temperature extremes, UV radiation.
4. Polyurethane-based varnishes can be used for various surfaces. They are environmentally friendly, odorless, dry quickly.
5. The basis for oil varnishes is natural oil or drying oil. Advantages: environmental friendliness, no smell, moisture resistance. Disadvantages: prolonged drying, darkening after some time after application.

How to choose wood varnish for interior work

Varnishes for indoor use are distinguished by their rigidity and durability of the coating, which protects against possible mechanical damage. They are absolutely safe for human health, have no smell, brightly reveal the texture of the tree.

Such varnishes are used to cover furniture, wooden or parquet floors, interior details. For interior work, varnishes on acrylic, alkyd, oil, alkyd-urea, nitrocellulose, polyurethane bases are suitable.

How to choose wood varnish for outdoor use

Lacquers for outdoor use form an elastic film that can withstand adverse weather conditions: temperature extremes, UV radiation, aggressive acids and alkalis. Wooden benches, terrace boards, house facades, garden furniture, etc. are varnished. For this, alkyd-urethane, alkyd, polyurethane varnishes are suitable.

What is the best varnish for the floor

• One-component varnish is preferred for floor coverings with low to medium surface stress. Among its advantages are ease of use and more affordable cost.
• Two-component varnish is more resistant to mechanical and physico-chemical effects, and therefore it can be used for floors with high traffic.

How to choose parquet varnish

For floor coverings, varnishes with increased resistance to deformation are needed. Before buying, it is worth considering the expected load on the room, for example, wear-resistant polyurethane products would be ideal for a kitchen or corridor, and alkyd varnishes or water-based varnishes can be used in a bedroom or living room.

Which varnish is better for parquet: alkyd or water-based

Alkyd varnish has greater wear resistance, but when dried, it releases substances harmful to health. In children's rooms or bedrooms, it is recommended to use eco-friendly and hypoallergenic water-based varnishes.

Before choosing a varnish for a floor made of pine, oak or other wood, it is important to pay attention to the degree of gloss of the paint and varnish. Depending on the brightness of the light reflected from the surface, the following varieties are distinguished:

• high gloss;
• glossy;
• semi-gloss;
• semi-matte;
• matte.

What varnish to choose for furniture

Furniture varnishes should not only give an aesthetic shine to the product, but also protect it from external influences. It is important that they are fireproof, resistant to moisture, abrasion, scratches. For painting furniture, the most popular varnishes are polyurethane and acrylic based. They are easy to apply and completely eco-friendly. Bituminous varnishes are used to give the effect of aging.

Lacquer for stone and concrete

Lacquer for stone and concrete provides reliable protection of building structures from weathering, pollution and destruction. For these purposes, polyurethane, bituminous and alkyd varnishes are most preferred. Acrylic varnish is used to emphasize the decorative properties of the stone.

deck varnish

The so-called deck or yacht varnish is made on a polyurethane-alkyd basis. It is especially resistant to the damaging effects of salt and fresh water, wind, ultraviolet rays, therefore it is used for painting river and sea vessels, as well as window frames, facades, doors.

To protect the wooden base for a long time and give it a presentable appearance, wood varnish should be used. If you know how to choose the right composition, you can significantly improve the performance of the product.

Varieties of varnishes for wood

The composition and characteristics of the varnish used can vary significantly. Manufacturers offer a wide range. We offer you to get acquainted with the main varieties used for wood processing.

A wide range - a wide range of possibilities

Oil and resin

Relatively recently, oil varnishes for wood were very popular. Now they are used somewhat less due to the emergence of other options. The basis is resin and oil, which are mixed in certain proportions. Initially, natural ingredients were used. Later, to reduce the cost, artificial resins and modified oils were introduced into the composition.

Oil varnishes, depending on the percentage of oil, are usually divided into:

• fatty (65-85%);
• medium (55-65%);
• skinny (35-55%).

The first ones dry much longer than the skinny ones, but they perform a better protective function. With their help, most often protect the flooring in residential buildings. Given the high density of the compositions, they are usually diluted before application. Oil varnishes for wood are stored for a short time. For their complete drying, it takes from 1 to 3 days.

Oil varnish takes a long time to dry

The basis of resin varnishes is natural (for example, amber), thermoplastic or thermosetting resin. Their area of ​​​​use completely coincides with the area of ​​\u200b\u200buse of oil formulations.

Alkyd, alkyd-urea and alkyd-urethane

The basis of alkyd is glyptal or pentaphthalic resin. Solvent or white spirit is used as a solvent. Manufacturers also add special substances that accelerate the drying process of the applied composition. The formed coating is not afraid of moisture. Retains properties during temperature changes. Remains unchanged in direct sunlight.

Alkyd varnish has a long shelf life, reasonable cost and an unpleasant odor. Allows you to emphasize the natural texture of wood. Applying several layers allows you to achieve the desired color depth. It may take 2-3 days for each applied layer to dry. Due to its good wear resistance, the composition is used for the treatment of floors, including heated ones. Rarely used to cover furniture.

In the composition of alkyd-carbamide varnish for wood, in addition to alkyd resins, amino-formaldehyde resins are introduced. They are two-component materials. In order for the formed coating to harden, an acid-containing hardener is added to the base. The prepared mixture has a limited shelf life, which, depending on the brand, is a couple of hours or several days.

As a result, a durable film is formed on the surface of the wood, providing a sufficient level of protection against moisture. Alkyd-urea grades are used mainly for processing parquet or massive floor boards. They are also in demand in the processing of wooden furniture and various interior items.

The basis of alkyd-urethane varnishes is alkyd resin, to which a group of urethanes and an organic solvent are added. The introduction of additional components made it possible to double the service life of the formed coating compared to the alkyd counterpart. The substance has an unpleasant odor. Protects the tree from the effects of negative factors. Used to treat ship surfaces.

Acrylic and acrylic urethane

Acrylic varnish is an environmentally friendly and safe composition that does not have an unpleasant odor. Can be used to treat bases in children's rooms. Water-soluble formulations dry for a long time. It may take about two weeks for the film to form. Before applying the composition, the tree is primed.

Attention! Manufacturers offer acrylic varnishes for wood containing up to 15% solvent.

Water-based preparations emphasize the natural beauty of wood, but do not provide a sufficient level of protection against moisture. They do not support combustion. The mechanical characteristics of the coating are relatively low. Manufacturers significantly improve them by introducing special additives.

For processing inside and outside

Acrylic urethane varnish can be diluted with water. It has almost no smell. Possesses the high level of adhesion to the basis. It can be applied at temperatures above +12ºС, and during its storage the value should not fall below +12ºС. It is used when performing finishing work inside the bath, sauna.

alcohol and epoxy

Alcohol varnish for wood is of limited use. It is based on resin and ethyl alcohol. The latter evaporates quickly, so it takes 20–60 minutes to dry the formed layer. The coating does not protect the wood base from moisture well, but it has a beautiful sheen. With its help, musical instruments are varnished, sometimes furniture.

The basis of epoxy varnish is the resin of the same name. It is a two-component drug. Hardening of the formed layer is possible only after adding a certain amount of hardener. Allows you to get a hard coating with a sufficient level of moisture resistance and resistance to shock loads. It is used when performing internal and external works. With its help, floor coverings are varnished. It takes no more than half a day to dry the applied layer.

Epoxy varnish - two-component composition

polyester and polyurethane

Polyester varnish is a multicomponent composition. Its base is polyester resin. A special gun is used for application. The process is quite labor intensive. Requires some skill and precision. After drying, a durable thick film forms on the surface of the wood, providing a sufficient level of protection against moisture and aggressive substances. Ideal for furniture, floors and some musical instruments.

Polyurethane varnish is the most popular. This group includes yacht varnish. Due to the high strength and hardness of the formed coating, it can be used everywhere. Differs in the increased adhesion to the basis. Resistant to direct sunlight and chemicals. Dries fairly quickly (4-12 hours). Can be used for outdoor work. Demanding to adhere to the application technology, since even a small amount of water can significantly impair performance. Has a high cost.

Advantages and disadvantages

The advantages of varnish for wood include:

• protection from biological impact;
• increased resistance to mechanical damage;
• resistance to sun exposure;
• improving the appearance of the base.

Of the shortcomings, it is worth noting the long drying time.

How to choose wood varnish: basic criteria

To purchase a suitable composition will help a number of criteria that should be taken into account when choosing a varnish for wood. The main attention should be paid to the purpose of the purchase, the appearance of the coating being formed and its performance characteristics.

By area of ​​application

The scope is of fundamental importance. Varnish for wood is divided into solutions for interior and exterior use. Based on the purpose, various substances are introduced into their composition. For outdoor surface treatment, coatings must have properties that allow them to resist atmospheric precipitation and physical attack. Internal work is carried out with a composition that is safe for human health. The surface treated with varnish for interior work, under the influence of the sun and atmospheric precipitation, will quickly crack.

Operating conditions are an important criterion

According to the degree of gloss

The degree of gloss of the formed coating may vary. When choosing a varnish for wood, it is imperative to take into account the design of other interior items and the overall stylistic design.

Advice! The degree of gloss of the formed coating depends on the order of its formation, subsequent polishing, the characteristics of the substrate and the selected shade.

Gloss level may vary

For wear resistance and fire resistance

With a significant mechanical impact, increased requirements are imposed on the level of wear resistance of the formed coating. When choosing a composition for parquet, you should immediately pay attention to the polyurethane varnish for wood. The formed coating will have sufficiently high wear resistance. The degree of abrasion will be minimal.

Attention! You should refuse to buy nitrocellulose varnish. Its wear resistance is the lowest.

Wear resistance must be sufficient

Refractory lacquer is used for finishing premises, which are subject to increased fire safety requirements. Its compliance with regulatory requirements is confirmed by the appropriate certificate. To ensure a sufficient level of fire resistance, the composition must be applied in compliance with technological requirements.

Drying speed and toxicity

Often, the drying speed becomes the main criterion when choosing the right composition. The timeliness of finishing work depends on this. The curing time directly depends on the brand and base of the wood varnish. The minimum period shows a water-based varnish. The longest time will have to wait for the coating formed using nitroglycerin.

When working indoors, the toxicity of the composition is of particular importance. The most harmful are varnishes containing solvents: nitro-lacquer, acrylic, polyurethane for outdoor use, polyester. With their help, finishing should be done in a workshop or non-residential premises. If the base in the living room is varnished, the residents should leave it for the duration of the work.

It is better to perform work on a dry, windless day at a temperature of more than + 10ºС. The optimum temperature range is within 15 - 35ºС at a humidity level of less than 80%. The process itself includes the following steps: tool selection; foundation preparation. The old coating, dust, and existing contaminants should be removed from the surface. If there is a fungus or mold on the base, this area is disinfected. Wood is sanded with a grinder or sandpaper; applying a primer. This stage can be abandoned, however, priming will level the base and reduce varnish consumption; applying varnish with the selected tool after the primer has completely dried; polishing of the formed layer. Advice! You can remove old varnish with baking soda. With a sprayer Used for a large area of ​​processing or when applying varnish on a base with a complex relief. Allows you to form a uniform layer.
