Despite the proliferation of new materials for making doors, wooden structures are the most popular, especially in private housing. A varnished surface looks much more impressive than a painted one, emphasizes the beauty of the wood and makes the door more presentable. This article will discuss how to varnish a door.

Lacquered doors look more luxurious than simply painted ones

Varnish selection

There are several types of paints and varnishes that are used when varnishing doors.

1. Alkyd. They include solvents that give the wood a yellowish tone and are resistant to moisture. To improve drying ability, increase moisture resistance and strength, so-called hardeners are often added to the composition. The drying time for a surface coated with such paintwork is approximately 24 hours.
2. Acrylic. Manufactured at water based. Odorless and non-toxic. To increase strength, hardeners can be added to the varnish composition, since without it the composition does not have good strength characteristics.
3. Nitrovarnishes. The main advantage is very fast drying. The basis of this varnish is solvents. The disadvantage is increased toxicity, which often makes its use unjustified. The best way application - spray gun.
4. Polyurethane coatings are durable. Polyurethane gives a dark tint, so the surface of the door needs to be primed.

There are other varieties that can be used when varnishing a door. However, the ones listed above are considered the most common.

Pay attention! There is a pattern: the more toxic the varnish, the higher its consumer properties.

Alkyd varnishes are more resistant to moisture, so it is recommended to use them in rooms with high humidity(for example bathroom)

Materials and tools

To carry out preparatory work and further varnishing you will need:

• brush or roller;
• cotton rags;
• spatula;
• wood putty;
• grinding machine;
• sandpaper (both fine-grained and coarse-grained);
• construction hairdryer

Preparing the door

Before varnishing the door, it must be sanded, removing all irregularities and roughness. One of the sanding options is a board (25x10 centimeters) wrapped sandpaper.

Sanding is an important operation, so you need to treat it carefully. Moreover, this stage is quite labor-intensive. You can also use a grinder - this will speed up the process. All kinds of cracks, cracks and other defects are sealed with putty. Pay attention to the color of the putty as this will affect the final appearance of the finished door.

It is very important to clean the door thoroughly before varnishing.

Next, the door is treated with a special impregnation that protects the material from mold and bark beetles. To improve the quality of varnish and reduce varnish consumption, the surface is primed. The primer is applied with a brush or roller.

WITH work surface you need to remove the dust and degrease it with white spirit. If you plan to paint the doors, they can be treated chemical composition. However, this does not need to be done before varnishing, since the remover will saturate the wood and negatively affect its color.

Important! The primer, impregnation and varnish must have an identical base. If this is not the case, incompatibility of the components will lead to delamination of the coating. In connection with the above, it is recommended to purchase all components from one manufacturer.

After priming, we carry out another sanding using either #180 sandpaper or a sander. The sanded surface is re-primed.

After opening the jar, you need to slowly stir the composition. This prerequisite, since only slow stirring avoids the occurrence of air bubbles. Next, you need to pour a little varnish into the prepared container. The door is removed along with the frame and laid horizontally.

To ensure a smooth transition between layers, paintwork materials must be applied promptly. The varnish layers are applied overlapping, and their number must be at least three. Each layer must dry completely (after approximately 12 hours), and only then can the next one be applied.

Pay attention! Different varnishes have different drying times. More precise information on this issue can be found in the instructions.

The varnish is applied to the panels with a brush small size. The resulting sagging and drips are eliminated with sandpaper (except for the last layer). Until the paintwork material dries, the brush or roller can be kept in a jar of varnish or in a closed bag.

Pay attention! While working, some craftsmen leave door handles in place, wrapping them to protect them from varnish. This is wrong. The fittings must be removed to cover hidden areas with impregnation and primer.

If you need to varnish a door with a previously applied coating, you will have to remove old layer varnish or paint. It is important to thoroughly remove all old paint or varnish. It will depend on this appearance doors after varnishing. However, for optimal preservation of the varnish coating, varnishing over old varnish is sometimes allowed.

The door varnishing process does not apply to complex operations. However, you must not only be careful, but also not forget about safety precautions: use protective gloves and ventilate the room well.

Today the market offers a wide range of input and interior doors. But despite the variety of new materials, many prefer to choose the classics - wood. Such doors are excellent as interior doors, and some use them as entrance doors. Wood makes the door look presentable. But for such a structure to look beautiful, it needs care. To do this, purchase a special varnish for doors. What types does it come in? How to varnish a door correctly? All this will be discussed later in the article.

Types

At the moment, two types of door varnishes are popular:

Alkyd varnish

Among its advantages it is worth noting low cost. After drying, the composition forms a durable protective film. For application, you do not need to purchase special equipment or strictly follow the instructions. This door varnish also dries quickly. After an hour, initial polymerization occurs. And after a day the layer acquires full strength.

Wood varnish PF-157 gets good reviews. It serves to protect the material from atmospheric and biological influences. Ideal for decorative finishing.

But do not forget about the disadvantages of such varnishes. The disadvantages include the short service life of the coating. Such a door has to be updated once a year. The surface fades in the sun and loses its original color. In addition, when evaporated, the chemical components contained in the composition are harmful to human health. Since the composition emits a pungent odor when applied, it is used mainly for external doors.

The composition of the varnish includes dissolved in organic solvent. The product is resistant to moisture. But, significantly afraid of tall or low temperatures. The optimal mode is from 5 to 30 degrees Celsius.

Acrylic varnish

It is used when it is necessary to carry out work indoors. Among the features of this material it is worth noting:

• Instant drying due to water evaporation.
• No toxic substances that could cause allergies.
• Shine coating.
• Elasticity of the material.
• The protective layer is not prone to chipping and cracking.

The only downside is the high cost. By the way, yacht varnish for wood also belongs to acrylic. It is expensive, but it protects the surface efficiently. If you need to protect the tree for a long time, it is recommended to purchase acrylic compounds.

What to look for when choosing?

The first step is to decide for which door the material is being purchased. If this is an interior room, you should give preference acrylic compounds. For the entrance, you can use alkyd varnish. Humidity also matters. For the bathroom you need to buy moisture-resistant products.

You need to decide what kind of coating you want - matte or glossy. The latter will highlight all the irregularities. Therefore, if there are defects in the coating, it is better to choose a matte varnish for the doors.

Preparing for work before updating the door

How to paint entrance or interior doors made of wood? First you need to prepare:

The first step is sanding with coarse paper. This will remove all the unevenness. For a high-quality result, you can use a board wrapped in sandpaper.

The grinding procedure must be treated carefully. To make work easier, you can use grinder. Using putty, all defects are repaired - chips, crevices, cracks. It is important that the color of the putty does not differ from the wood. Next, the door is treated with impregnation, which protects the material from mold and bugs. A primer will not be superfluous; this will significantly reduce varnish consumption. The primer is applied with a roller or brush.

If you also plan to paint, degrease the working surface using white spirit.

An important point: impregnation, varnish and primer must have the same base. Otherwise, the coating may delaminate. Therefore, it is advisable to buy everything paint and varnish materials from one manufacturer. After applying the primer, sand the surface again. But this time, fine-grained is used.

Varnishing

Next, you need to open the jar and stir the composition. This will eliminate the presence of air bubbles in the varnish. Then pour a small amount of paint into the prepared container. The door is first removed from the frame and installed horizontally.

The varnish is applied promptly to prevent transition between layers. It must be applied in an overlap. The number of layers is at least 3. Each of them must first dry. This takes about 12 hours.

We also note that varnishes from different manufacturers have different drying times. Therefore, pay attention to what is written on the packaging. What to do when sagging and drips form? They can be removed with sandpaper. But such manipulations can be done on the first two layers. You cannot use sandpaper at the finish, otherwise the appearance will deteriorate.

Please note: while the layer is drying, the brush should be in a closed bag or in a jar of varnish. Otherwise, the product will crystallize and it will be impossible to work.

To avoid damaging door handles during varnishing, it is advisable to wrap them masking tape. It is not recommended to use regular one, as it leaves traces of glue. But the paper one is perfect. But, if it is necessary to process all hidden places, it is advisable to disassemble the fittings.

It is also recommended to completely get rid of the old protective coating before applying a new coat of varnish. This will not only have a positive effect on the appearance, but will also extend the life of the protective surface. Don't forget about safety precautions. Experts recommend working with protective gloves. And if it is an interior door, it is important to ventilate the room well (even if it is acrylic varnish).

How to artificially “age” a door?

Recently, such works have become popular. You can create a “antique” effect by brushing. What is it? This is a simple technique for “aging” doors. For this purpose it is used iron brush. With its help it is removed top layer tree. This is done until the annual rings appear. However, this method requires the use of a thick layer of varnish.

Another method is “aging” with wax. Here you need to adhere to a certain sequence. First the wax is applied. Next is painting in a light tone. After drying, the paraffin is removed using a spatula. Next, the base is sanded. Then stain or varnish is applied. As experts note, it is this method that makes it possible to create the maximum “antique” imitation.

Conclusion

So, we found out which varnish to choose for doors and how to apply it to the surface. The choice of material depends on many factors. But still, to get a high-quality result (especially if the door is expensive), you need to use yacht varnish for wood. It provides maximum protection and does not cause allergic reactions. It can be used to process both interior wooden doors and entrance doors.

Perhaps the tree is still considered one of the most popular building materials. Previously, it was used almost everywhere, but today the demand has decreased significantly. Many people prefer to deal with stronger and more durable materials. But upon registration interior design few people can ignore the use of wood. Take, for example, an interior door with its processing features and variety of patterned decorations. No matter how well prepared for use wood material, it should definitely be varnished. Otherwise, the appearance of your products will deteriorate over time, and it will be impossible to restore it to its original beauty.

Choosing the right varnish

Have you decided to use varnish? You made the right choice. All that remains is to correctly select the necessary material to process your doors. Varnish compositions are divided into several types:

• Alkyd compounds are an excellent waterproof, solvent-based option. After application it creates a light yellow tint. In order to speed up drying, it is allowed to add a hardener. This combination will increase the hardness and moisture resistance of the coating. Complete drying time after application is twenty-four hours.
• Nitrovarnish compositions - capable of drying quite quickly, are made on the basis of solvents. Very toxic material, easy to use with a spray gun.
• Polyurethane varnish composition - has high strength, can give wood dark color. Before applying it, it is recommended to treat the surface with primer compounds.
• Acrylic varnish is safe from an environmental point of view, since it contains a water base. This type of varnish is odorless, but is not as durable as other compositions.

How to prepare a door

If you decide to update a door coated with varnish or other protective material, it should first be prepared.

2. Now let's move on to the second preparatory stage - grinding the door surface. This is necessary in order to remove all defects that appeared during primary processing. This procedure is performed using fine sandpaper. To carry out sanding work, you need to be patient, this will help you achieve good results.
3. If paint is used, the procedure for leveling with sandpaper could be replaced with conventional puttying of the surface. Painting with varnish involves the use of putty, but in small quantities to seal knotty areas and deep damage. It is very important to match the color of the putty to the color of the wood from which your door is made.

Pay attention! Never use removers designed for metal work. as they quickly absorb into the wood, coloring it. For each type of coating, the appropriate type of wash is selected.

Next preparatory stage– treatment of the door surface with a special impregnating composition, which will serve as protection against mold and bark beetles. After the impregnation has dried, apply the primer mixture using a roller or brush. It will create conditions for better adhesion of the surface to the varnish and slightly reduce its consumption. When carrying out all activities, it is necessary to make a selection of materials on the same main component so that the effect of delamination does not appear. We advise you to choose everything necessary materials from one manufacturer. When the soil dries, you need to work a little with sandpaper again. Areas of additional cleaning should be additionally coated with a primer mixture. If you have chosen a varnish that will not change the color of the wood, you can use it as a primer after diluting it.

Varnishing the door

Remember how to varnish a door. First you need to prepare everything necessary tools. You will need:

• narrow roller;
• the same narrow brush;
• a container for varnish (a bath is best);
• sandpaper.

3. If it is necessary for varnished wood to dry quickly, use nitro-cellulose varnishes, or nitro varnishes, as they are popularly called. They come in transparent types that form a shiny, transparent coating on the wood while preserving its natural color and texture. There are also matte finishes, after which the surface becomes slightly silky with a muted color. There are acid-curing nitrovarnishes with the addition of urea resins. They increase frost resistance, moisture resistance, and protect against sudden temperature changes. The advantages of nitro varnish include reliability, durability, and accelerated drying rates. Its main drawback is increased toxicity. Therefore, it is best to apply such substances with a spray gun. Price - 320?600 rubles per liter.
4. Polyurethane varnishes are particularly resistant. They are resistant not only to atmospheric influences, but also to hydrochloric and sulfuric acid, ammonia, mechanical damage - shock, abrasion, cutting. However, such material can sometimes darken the wood, so it requires a primer.

This should be done with sandpaper with a fraction of 60 to 180 (depending on how serious the flaws need to be eliminated). If this procedure was not enough and the unevenness is still noticeable, you can use wood putty of the appropriate color.

In the photo, Drevotex (1 liter) is a preservative, difficult-to-wash-out antiseptic for protecting wood, the price of a liter is 72 rubles.

Next, using a brush or roller, special substances are applied that protect the wood from fungus and bark beetle (wood antiseptics). Then the door is primed. When carrying out all these procedures, it is necessary to ensure that the impregnation, varnish and primer are on the same base (it is better if they are from the same manufacturer). After priming, go over it again with sandpaper and apply another layer of primer.

To apply varnish to the door, you need to prepare a narrow roller and a narrow brush, a special tray and sandpaper No. 400. The door must be coated in a horizontal position, very quickly, so that the transitions are invisible. As a rule, the procedure must be repeated three times, waiting until the previous layer has completely dried. After each application and drying, imperfections on the surface must be removed with sandpaper (except for the last layer).

Before varnishing, all hinges and locks must be removed so that the entire surface is covered and, accordingly, protected from various external influences. To have an idea of ​​what the door will look like after varnishing, you can make a few test strokes on its end side and wait for it to dry.

Most often, when restoring a wooden door, preference is given to 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. A shiny transparent glaze will highlight the beauty of natural wood.

Acrylic paint

The best choice to paint wooden interior 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. Thin layer allows the tree to “breathe”.

Acrylic enamels dry quickly, and after painting there is no toxic odor indoors. Another advantage is large selection flowers. The disadvantage is the high cost. After drying, the surface becomes matte. Additional autopsy acrylic varnish further increases the cost of painting a wooden structure.

The dried layer of paint is completely harmless to humans and preserves bright color for a long period of use 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. The varnish creates a decorative shine on the door and also additionally protects it from moisture.

Painting veneered fabric

A wooden door covered with veneer cannot be painted with compounds based on aggressive solvents. First of all, this applies to nitro paint. Due to chemical exposure, matte spots will appear on the veneer. It is better to choose water-based, glyphthalic or polyurethane-based tinted varnishes.
