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 withstand 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 paintwork material is versatile, as it is used for painting facades, fences, terraces, etc. On the surface, it forms a durable coating 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:
- Sand the surface thoroughly. Use sandpaper of different grits for this. Work can be done manually or using grinders.
- Remove all dust with a vacuum cleaner.
- 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.
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. We offer you to get acquainted with the main types, their distinctive features, methods of application.

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 PHOTO: antiquepurveyor.com
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.

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 analogue. 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 PHOTO: i2.wp.com
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.

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 laborious. 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 PHOTO: vagonkapinsk.by
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 PHOTO: teleplast.de
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 PHOTO: antiseptiki.com.ua
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.

The composition applied with a sprayer must have a suitable consistency.  The coverage is even PHOTO: azurka.ru With a brush or rollerWhen choosing a brush, take into account the composition of the wood varnish. For oil, you should choose a tool with natural bristles. A brush with synthetic bristles will help to form a smooth surface. The roller is used when processing a large area. On a horizontal base, varnish is applied in stripes. If the surface is vertical, make cross movements. After the applied layer has dried, the wood is treated with fine sandpaper. After that, a second layer is applied.

Over time, many materials lose their original appearance. Wooden products and buildings are exposed to external factors and need regular updating. To restore wood, it is recommended to use wood varnish. Unlike paints, it has a transparent texture, which helps to preserve the original drawing.
The varnish will give an aesthetic appearance and emphasize the natural beauty, as well as reliably protect the product from adverse effects and prevent its destruction.
Wood varnishing
The principle of working with varnish on wood is to apply it to the surface. As a result, the solvent that is part of the substance will evaporate and a dense and shiny film will remain. These simple actions will help extend the life of the wood.
Of course, for an impeccable result, a number of preliminary measures must be performed. First, sand the wooden surface, remove the remnants of old paint or varnish. Be sure to remove any remaining dust after sanding.
Secondly, it is very important to apply a primer first. This will avoid the appearance of bubbles and prevent the formation of small defects.
Then you can already apply varnish, pre-selecting the desired tone. Thanks to a wide range of goods presented on the sales market, you can choose the right color for the interior of the room.
Types of varnishes
It is necessary to choose a varnish taking into account the upcoming work (internal or external) and operating conditions (humidity and temperature levels).
Consider the following most popular categories of varnish products:
Oil varnish
Oil solutions based on the composition have vegetable oils and resins. This is a wood varnish designed for interior use. They are distinguished by the degree of fat content.
Accordingly, the fatter the agent, the better the protective layer. Colorless varnish in this category is more popular, as it helps to preserve the natural texture of wood.
Alkyd varnish
Alkyd varnishes are versatile in use (intended for internal and external manipulations). They have increased resistance to external adverse conditions, are not afraid of moisture and high (low) temperatures. This safe and environmentally friendly product has a relatively low cost.
alcohol varnish
Alcohol varnish is based on ethyl alcohol and resin. It is mainly used to cover furniture accessories and musical instruments.
Acrylic lacquer
Acrylic varnish for wood is odorless, contains antiseptics designed to combat mold and fungi. It is very convenient to use due to plasticizing additives that allow modeling the substance. Presented in a wide range of colors, environmentally friendly to use.
water varnish
Water-based wood varnish contains water, emulsifiers and in some cases solvents (from 5 to 15 percent). Despite the fact that it dries much longer than other products, it is in demand among buyers due to the correspondence between price and quality. They are absolutely non-flammable.
polyester varnish
Polyester based on polyester resin creates a dense, thick, glossy, water-resistant film. It is applied exclusively with the help of a special tool.
Polyurethane varnish
Polyurethane, on the contrary, has a pungent odor and hardens for a long time, but in the end it forms an unconditional protective layer.
Alkyd-carbamide varnish
Alkyd-urea varnish is considered very durable and water resistant due to the acid hardener, urea and resin it contains. Excellent for covering parquet, as it has a special shine.
Conclusion
Well-known manufacturers represent a wide range of wood varnishes. They are characterized by the type of application (internal or external use), by the type of solvent taken as a basis and by the degree of gloss.
So, oil varnish will protect the surface from dust and dirt, and alkyd ones can create a barrier against moisture. Alkyd-carbamide are designed to strengthen the surface and create a more durable coating.
When choosing, it is necessary to take into account the gloss of the varnish. Exclusive options are already presented on the sales market - these are tinted varnishes. With their help, you can change not only the shade, but also the color of the tree.
To decide where to buy wood varnish, you need to visit several hardware stores, study the range of each, consult with experts and select the right product.
The price of wood varnish will directly depend on the performance characteristics of the product and the brand of the manufacturer.
Photo varnish for wood
For outdoor woodwork, a special frost-resistant varnish should be used. This composition can be used to decorate and protect wooden products that are outdoors.
Exterior varnish will extend the life of wooden surfacesIn winter, negative temperatures can significantly affect wooden structures, which worsens the performance properties of the surface. For example, if moisture penetrates 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 outdoor work must have pronounced water-repellent properties.
Today, frost-resistant paints and varnishes are actively used for painting such wooden surfaces:
- roof elements;
- steps made of wood;
- porch;
- outdoor wooden furniture;
- terrace board;
- 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
To date, the choice of varnishes is great, the main thing is not to make a mistake, and for this you need to know a number of criteria that are listed below Today there is a wide choice of paint and varnish coverings for external works. 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 basis. Any of these compositions forms an elastic film after drying, which increases the resistance of the surface to mechanical stress at low temperatures.
In addition, the paintwork material for outdoor use contains various chemical additives that protect the coating from fungal attack, UV radiation, cracking and discoloration.
The key characteristics on which the effectiveness and frost-resistant coating depends:
- water-repellent properties;
- permeability to vaporous substances;
- resistance to mechanical deformation;
- resistance to the influence of ultraviolet rays;
- impact resistance.
The main types of frost-resistant varnishes, depending on the composition:
- solvent-based paintwork material;
- water-based varnishes;
- compositions on an alkyd-urethane basis;
- oil solutions;
- yacht paint and varnish compositions.
Yacht varnish is frost-resistant, wear-resistant and high-strength Types depending on the purpose:
- universal compositions;
- varnishes for wooden furniture;
- glossy paint coatings;
- matte finishes.
Popular paints and varnishes 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 chemical attack by detergents. However, solvent based coatings can change the color of the wood surface by adding yellow tones.
Frost-resistant water-based varnish is not as resistant to abrasion. At the same time, such material is considered more environmentally friendly. In addition, the water-based material dries faster than all others.
The most durable is considered to be a varnish created on an alkyd-polyurethane basis. It has excellent performance. A feature of oil paints and varnishes based on natural resins is that they can change the color of the floor in the country or other wooden surface, making it darker.
Today, it has become popular for outdoor woodwork. This paintwork material has all the necessary qualities in terms of elasticity and durability, which 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 technique
Frost-resistant varnish should be used only after the surface has been impregnated. The paintwork is recommended to be applied in 2 or 3 layers. All work must be carried out at a positive temperature. The coating material can be applied with a conventional brush, roller or pneumatic sprayer. If you are going to work with a sprayer, then it is best to dilute the paint composition. The solvent, which must correspond to 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 application of the next layer should be carried out 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.
Processing wooden surfaces with colored varnish allows you to emphasize the textural features of a particular type of wood, which creates a beautiful decorative look. The varnish also performs a protective function. It forms a reliable protective layer that prevents the destruction of the wooden surface. Colored varnish for wood for interior work closes the pores of wood, which prevents the release of phytoncides and various natural odors.
Wood varnish for interior work is a special construction-type composition, with which the wooden surfaces of floors, various furniture, doors, stairs and other surfaces made of various types of wood are treated. Colored lacquer provides protection against the penetration of moisture and various cleaning agents, does not allow mold and fungi to destroy wood, and also provides protection against mechanical impact (impact, falling objects, friction).
People choose colored polish for the reason that it creates a certain look. Beautiful and rich tones of the wood texture allow you to carry out any design ideas and solutions. There are several varieties of colored varnish for wood, but the most popular is polyurethane varnish. This is a chemical composition based on polyurethanes and other compounds and additives. This varnish is excellent for processing floorboards, parquet, various laminates (colored floor varnish), wooden walls and ceilings, various elements of wooden interiors, and furniture.
Coating with ready-made colored varnish or tinting and subsequent varnishing of wood?
When a wooden product is new, it does not have such a beautiful appearance. To give it a certain beauty, it is necessary to process it with a special coating. There are two options for coverage. The first option is to cover wooden surfaces with ready-made colored varnish. The second option is pre-tinting in the desired color and subsequent varnishing. What type of coverage is best?
Applying colored varnish can significantly save both money and time. To cover using tinting, you will have to buy tinting and colorless wood varnish, in the case of colored varnish, you only need to purchase varnish. When tinting, it will be necessary to cover the wood in one layer of stain, then several layers of varnish, each layer must dry for a certain time. So it will take quite a long time.
Basic methods for applying colored polyurethane varnish for wood
Before applying colored varnish, it is necessary to perform a number of preparatory procedures. First you need to level the wooden surface. If the irregularities are large enough, then special tools must be used. If the irregularities are small, then they can be processed with a simple sandpaper. The surface must be even and smooth. If there are knots on the surface, they can be removed with a special chisel, and inserts made of the same wood can be glued in their place.
After grinding, all traces of dirt, dust and grease must be removed from the surface. To do this, you can use ordinary detergents and water. Polyurethane-based varnish is best applied to primed surfaces. The primer is applied evenly over the entire surface, very carefully it is necessary to treat hard-to-reach places. The primer must saturate the entire surface. It is best to apply a primer layer with a brush with a sufficiently high stiffness index.
When the primer is completely absorbed, you can start processing with colored varnish. The varnish is applied with a synthetic brush. It should lay down in an even layer. Do not allow sags and streaks. Colored polyurethane varnish is applied in 2-3 layers. Before applying the next layer, the previous one must dry thoroughly. During the final drying, it is necessary to close all doors and windows in the room, air movement must not be allowed.
