Why is there a need to apply any coatings to wooden doors? Wood is a natural material. It is capable of absorbing and releasing moisture, changing its characteristics depending on the conditions in which it is located. When exposed to excessive moisture, wood can swell, and when exposed to sunlight, it can dry out and warp. At the same time, wooden doors can change color, size and shape. To avoid all this, it is necessary to take measures to protect the wooden surface. This is why there are various coatings.

Protective coatings for wood must have a number of characteristics to ensure a long service life of wooden panels and maintain their aesthetic appearance. Sometimes protective coatings are confused with wood impregnations. Impregnations have a slightly different purpose.

They are used to create the greatest resistance of wood to fungi, rot and fire. Protective coatings are designed to protect door leaves from environmental influences. Basic requirements for paint and varnish coatings for wooden surfaces:

• moisture resistance;
• resistance to solar radiation;

The opaque paint coating is applied in several layers, which contributes to its durability. The application of varnish is carried out in several stages:

• surface putty;
• surface primer;
• finishing with enamels.

Transparent paint coatings are used if the surface of the wood has a good appearance without major defects or damage. Then the transparent coating will only emphasize all the natural beauty of the tree. To achieve a transparent effect, varnishes are used.

After applying the putty and drying it, the surface is sanded sandpaper until smooth. The selected varnish is poured into a container that will comfortably fit the roller. It is dipped into varnish, the excess amount is squeezed out and the varnish is applied to the sample. After covering the entire surface, the varnish should dry completely. As a result, the canvases will become rough after drying. This is normal. It is necessary to sand the surface with sandpaper so that it becomes smooth, shake off the dust and varnish again.

When choosing enamel for windows and doors, take into account the characteristics of the canvas:

• The door block is made from different types of wood and waste from the woodworking industry. From density The amount of paint absorption before it dries depends on the material. An extra layer is an additional cost. When choosing an expensive paint and varnish material, it is wise to use drying oil. After impregnation, loose wood will be covered with a film, and paint absorption will decrease.
• The consumption of varnish or enamel for doors depends on the surface. Smooth It is enough to go through two thin layers of paint. Rough the material requires the application of more layers.
• When restoring door blocks, it will not be possible to completely remove the previous coating. New paint and varnish material should not contain aggressive substances, corroding old paint. During the reaction, swelling and peeling will appear on the canvas.

Additionally, when choosing a paint and varnish material, take into account intensity of use door block, as well as the level humidity And temperature environment.

Choice colors– this is a personal preference. The new canvas looks beautiful under clear varnish or with the addition of stain. After cleaning, it is better to cover the old door with enamel, choosing the desired color.

• Transparent It is better to paint new wooden interior or entrance doors with varnishes and impregnations. The applied layer is a decorative glaze that does not hide surface defects. A transparent coating can highlight the interesting structure of new wood.

• Opaque paints or enamels for windows and doors are made from solvents with added pigments. Under a new layer it is easy to hide wood defects, uncleaned areas of old paint, or simply give the door block a new original look.

Most often during restoration wooden sash They prefer opaque paints.

From a wide variety of interior work, it is best to choose safe water-based paint or varnish. From the street, a wooden canvas can even be coated with nitro paint.

Alkyd paint

It is advisable to use alkyd paint during overhaul when no one lives in the apartment. During this period, all toxic odors will have time to disappear. The dried surface can be matte or glossy, but in any case it repels moisture well.

Alkyd quick-drying enamel is characterized by the presence of a pungent odor. Its popularity is justified by the variety of colors, low cost, and resistance to aggressive environmental influences.

Alkyd varnish

Due to their transparent structure, it is better to cover a new wooden interior or entrance door. The disadvantage is the strong odor and long drying time. Shiny transparent glaze will highlight the beauty natural wood.

Acrylic paint

The best choice to paint interior wooden doors indoors. The advantage of the coloring composition is the absence of a toxic odor, as well as the ability to preserve the wood texture. A thin layer allows the wood to “breathe”.

Acrylic enamels dry quickly, and after painting there is no toxic odor indoors. Another advantage is big choice colors. It is considered a disadvantage high price. After drying, the surface becomes matte. Additional autopsy acrylic varnish further increases the cost of painting a wooden structure.

Acrylic lacquer

Acrylic varnish is perfect for covering a new, unfinished interior door. The non-flammable composition, harmless to human health, will preserve the color and texture of the wood. Wooden door leaf from the street side they are not coated with acrylic varnish.

Thermal enamel

They are highly toxic and can only be handled in well-ventilated areas. Nitro paint is suitable for the front door. If it needs to be removed in the future, it will not be easy to do.

Polyurethane paint

Gaining popularity polyurethane paints, characterized by good adhesion to wood. With proper preparation of the wooden surface, you can not be afraid of the appearance of blisters on the door. The dried layer of paint is completely harmless to humans and preserves bright color for long period operation and is also resistant to scratches. The main advantage of the polyurethane layer is elasticity. If the wood is slightly deformed, cracks will not appear in the paint.

Advantages of stain and varnish

For wood, stain and varnish not only give a beautiful appearance, but also additionally protect natural material from aging. A combined coating of two components is often used. The stain penetrates deep into the wood, where, together with tannins, it forms a protective barrier against moisture and preserves the natural color of the wood from fading.

How to cover a door with stain?

Wooden doors are rightfully considered one of the most aesthetically attractive. Despite the fact that the wood looks very good on its own, without paint and varnish materials It doesn’t work here, at least because exposed wood ages quickly, losing color.

What is stain?

Stain is a coloring composition that allows you to give wood a certain tone. This may be to restore the natural tone of a given type of wood during the restoration of the door, or it may be to impart a shade characteristic of completely different species.

Wooden interior doors or furniture elements are most often treated with stain.

The key difference between stain and other paint and varnish compositions is that it does not form a surface film, but is absorbed into upper layer wood. Thanks to this, there is a change in tone, but the texture of the wood is not hidden. On the one hand, this allows you to preserve the visual style natural wood. On the other hand, there is no protective layer that resists environmental factors.

Therefore, stain without subsequent varnish can only be used for interior doors.

What should you consider when choosing a stain?

• Same color written on the cans different manufacturers, can have a completely different shade. Always check the actual color of the stain.
• The final result after processing greatly depends on the type of wood, since each of them differs in density, natural color, texture, etc. For example, the effect of stain on maple will be almost unnoticeable, but poplar will darken greatly. The oak will darken slightly, but will acquire a more pronounced texture. Therefore, before applying stain to the surface of the door, it is worth testing its effect on a small area.
• Even the same breed can react to stain differently in different areas (due to uneven humidity, etc.). As a result, in some places you will have to apply the composition in several layers, but in others one will be enough. Choose the amount of stain with a margin.
• A water-based stain will dry in about 2-3 hours, while an oil-based stain will take at least a day to dry.

How is the door surface treated with stain?

The procedure is quite simple:

• The door leaf is laid in a horizontal position.
• The surface of the canvas is cleaned of dust, dirt and old coatings (if any).
• If the stain is water-based, you can dilute it to get more light shade. If you don't need this (or if you are working with oil composition) - you can use the solution directly from the commercial container.
• The stain is applied to the surface of the canvas using a brush or a regular rag. Pay attention to the uniformity of application - in some cases it is advisable to divide the canvas into several segments and work sequentially.
• If the stain is thick and forms clumps on the surface, they must be removed immediately.
• After applying the first layer of stain, it will immediately begin to absorb into the pores of the wood. Residues must be removed using a well-absorbing sponge.

After the first layer has dried, the second and subsequent layers can be applied.

Many manufacturers make doors without painting them first. This allows the buyer to independently select a specific type of paint that is suitable for the interior.

When purchasing such products, you should definitely pay attention to the quality of workmanship of all elements, as this guarantees long term operation. There are several types of materials that are used for such purposes. You can find out about all the characteristics.

But for more complex structures it is advisable to select more universal brushes, spray bottles, etc. Then we proceed to painting, which consists of several stages:

1. Applying primer. There are several types of these substances that should be selected for a specific type of tree. The number of layers can be individual, which allows you to get a better quality coating.
2. After this, staining is done. First, the surface is coated with stain, which gives the doors a certain tone and color. This is necessary in order to prevent darkening of the material, which this type of wood very often lends itself to.
3. At the very end, the canvas is coated with colorless varnish in several layers. Painting is done only after the stain has dried. To obtain durable coating, the varnish should be applied very carefully.

The painting procedure should be carried out only in a dry room, as moisture significantly reduces its quality. It is advisable to use only quality materials to obtain uniform, reliable and durable coating and adhere to all safety rules.

Treating the door before painting

An old door after paint removal or a new product is sanded before coating. This process involves smoothing the wood grain as much as possible to ensure even distribution. paint composition. If there are small dents or cracks on the canvas, they must be covered with acrylic putty to match the color of the wood. After this product has dried, sanding begins, which is carried out along the fibers.

The sanding process eliminates uneven surfaces on the door and ensures a smooth finish.

If bath or wooden entrance doors are treated, then after sanding you need to apply it to the wood. antiseptic and fire retardant. These substances can be purchased at construction supply stores, and they are applied to the canvas with a brush, distributing thin layer. To increase their service life, interior doors are often treated with an antiseptic.

Choosing paint for wooden doors

To create a dense and uniform coating, use paint suitable for processing wood products. Such products are presented in a wide variety and therefore, when choosing, you need to take into account certain features, for example, the operating conditions of the paint, the application method. The composition is also selected depending on where the doors are located. For example, entrance sheets are significantly affected by ultraviolet radiation and humidity, and the paint must protect the material as much as possible from deformation.

The paint for the door can be any color, but its high characteristics are important

The choice of paint is made taking into account the following features of door placement:

• for entrance doors you need a product intended for external use, resistant to low and high temperatures, humidity and ultraviolet rays. The paint should provide a dense coating to protect the surface from mechanical stress;
• for interior doors, the optimal compositions are those that do not have a strong odor and form a durable, durable, high-quality coating;
• Doors to the bathroom and other rooms with high humidity must be painted with compounds that are resistant to temperature changes and moisture, protecting the product from rotting.

Door paint should be thick and provide a durable finish.

Manufacturers produce many options for products, each of which has certain characteristics. The following compositions are suitable for wood:

• acrylic paint belongs to the group of water-dispersion paints and provides a dense coating. The product has a homogeneous structure and is easily applied to wooden surface. Acrylic paint suitable for interior doors installed in rooms with low humidity levels;
• alkyd compositions are based on a complex of thick resin, rosin, glycerin and vegetable oils. Enamels of this type require drying for 2-3 days, protect the wood from rotting and form a durable coating that is resistant to abrasion. Suitable for outdoor use;
• polyurethane products create a reliable coating that perfectly protects wood from moisture and scratches. The composition is easy to apply, as it is characterized by elasticity.

High-quality paint allows you to make the door beautiful and provide a durable coating

When choosing a wood treatment product, you should carefully study the information provided by the manufacturer and indicated on the label. This will allow you to determine the purpose of a particular paint option and whether the product characteristics meet the required level.

Processing a wooden door: applying paint

Painting a door made of natural wood requires certain tools. The composition can be applied with a brush or a special spray gun. In the first case, it is important to carefully and evenly distribute the product, and in the second, application is simple, but also requires precision movements. Using the brush is optimal at home, as there is no need to prepare the area for painting. You don’t even have to remove the door from its hinges, but just cover with film and masking tape those places that should not be painted. But in this case, you need to put a small amount of material on the brush to avoid drips.

You can paint a door with a brush at home

Work with a spray gun is carried out in utility room or outside in dry and warm weather. It is important to avoid dust getting on the surface to be painted, which is necessary to obtain an even coating. Treating a door with a spray gun involves the following steps:

1. Application masking tape to areas not subject to painting. Long screws are screwed into the upper and lower parts of the frame, and then the canvas is placed between two supports, that is, it must be suspended.

   The door leaf for painting can be placed on special supports

2. Preparing and stirring the dye, mixing the components if necessary (follow the manufacturer’s recommendations indicated on the packaging label). If the product is thick, then it must be diluted with suitable components, as indicated on the label. Place the composition in a special container of the spray gun, test painting the test boards.

   The paint composition is placed in the spray gun tank

3. The paint is applied to the surface using short sprays. All areas of the canvas, panels and other complex structural elements are carefully processed. After the first layer has dried, apply a second one, if necessary.

   The paint is applied along the wood fibers, which is important when using a spray gun, roller or brush

If the door is varnished, then opaque compounds treat the surface with sandpaper. This will improve the adhesion of the paint to the varnished structure. Only after this can you apply the paint using the chosen method: roller, brush or spray gun.

Door varnish technology

The method of applying varnish to a wooden door is slightly different from applying paint, but you can also use a brush or spray gun to work with it. In the second case, you will get a more even thin layer, emphasizing the natural structure of the wood.

The use of varnish allows you to make the door beautiful and emphasize the structure of the wood

Varnish comes in a wide variety and therefore it is important to know the features of the main options. Their classification varies depending on the area of ​​application, but the products differ significantly in composition. So, the following options are distinguished:

• water-based acrylic varnishes are used only for interior work, as they have low resistance to humidity, mechanical stress, and temperature changes;
• alkyd varnishes contain resins and vegetable oils, which makes them universal, they are applicable for interior and exterior work;
• Oil compositions form a thick and durable coating with shine. The drying period of the layer is about 48 hours;
• nitro varnishes are optimal for interior work, dry within 15–25 minutes, apply them in several layers;
• epoxy varnishes require mixing two components into the right proportions, can be used for external or internal work.

To obtain an even layer, stir the varnish thoroughly

In order to varnish a wooden door, you need to do the following:

1. Study the instructions for use of the wood varnish used. The composition must be stirred slowly and thoroughly, which will ensure uniform color and quality of coating.

   Any varnish should be thoroughly mixed before use.

2. The prepared composition is poured into the tank of the spray gun connected to the compressor. Test spraying is carried out on a test board. The door leaf is placed on supports, as is the case with paint. After this, they begin to apply the product.

   The varnish is applied evenly and in several layers

3. The composition is applied along the wood structure, observing equal but very short intervals between sprays. After the first layer has completely dried, you need to sand the doors with a sander and fine-grained sandpaper, remove the dust and proceed to further actions. The second and subsequent layers are done only after each previous one has dried.

   The varnished door looks solid and stylish

The technology for using stain is similar to the method for using varnish or paint. The main actions are expressed as follows:

1. Placing the canvas on supports, preparing and stirring the product.
2. Test spraying the stain from a spray gun or applying it to a test board with a brush.
3. Spray or brush evenly onto one layer of the door leaf.

The stain is applied in a thin layer and evenly

The gap between sprays or brush strokes should be minimal. This will avoid highlighting borders and differences in shade.
