Lacquer thick layer for wood. How to varnish a wooden countertop? Roller application

04.03.2020

Competent varnishing will help to give any wooden furniture its original look. Lacquering - varnishing is one of the most common methods of finishing both painted and unpainted surfaces of individual parts, assemblies and finished wood products.

Suitable for any wood. It is widely used in the production of inexpensive furniture, arts and crafts, as well as household items and various crafts. Before varnishing, the surface of the product is cleaned of dust and lint, which, being invisible, are clearly visible under the varnish film, especially with side lighting. Only well-dried wood can be varnished; high humidity can cause cracking of the varnish coating. As a rule, the varnish is applied in several layers. Before applying each subsequent layer, an exposure is made so that the previous layer is completely dry, after which the surface is polished. Reducing the drying time reduces the gloss of the lacquer.

To finish wooden products, alcohol, oil and nitrocellulose varnishes (nitro-lacquers), colored (from red to black), etc. are used. colorless (a thin film of such varnish is practically colorless, does not cover the natural pattern of wood and does not change the color of wood or paint coating, although, being in a glass jar, this varnish has a light yellow tint).

In carpentry, alcohol-based varnishes based on shellac and rosin are most often used. Alcohol-based varnish dries quickly, but does not resist moisture well. Alcohol varnish is best applied with a cotton swab wrapped in linen, but can also be applied with a brush, especially on small and profile parts. When using a tampon, the varnish is poured into the tampon in small portions so that its working surface, the sole, is slightly soaked. Then, with light pressure, the swab is quickly swept over the surface of the product (along the wood fibers) in only one direction, leaving a strip of varnish (las) on the surface. Each next las is carried out so that it only touches the edge of the previous varnish. As the varnish decreases, the pressure on the swab is increased. In places where the lacquers overlap, the lacquer layer is thicker, but usually it quickly spreads and levels out. If you use too thick varnish, lasses become noticeable. Excess varnish, formed on the edges and ends of the product, is removed with the same swab. With a brush, the varnish is also applied in one pass, usually along the wood fibers (especially for the first time).

As a rule, an alcohol varnish coating is made three-layer; mosaic surfaces made of various types of wood are covered at least 4 times. The first coating dries (stops sticking to the fingers) in 1-2 minutes, for subsequent layers, the drying time increases to 40-60 minutes. At home, it is extremely difficult to ensure a high quality coating with alcohol varnish, since it is almost impossible to quickly manually apply a thin, even layer of varnish on a large surface.

Compared to alcohol-based oil varnishes, they are less susceptible to the harmful effects of moisture and light, give the surface more shine, but dry more slowly (from 24 to 48 hours). During long-term storage, oil varnishes thicken and before use they are diluted with the oil on which they are prepared, or with turpentine. Oil varnish is applied to the surface of the product with a hard brush or spray. In the first case, light shading with a brush across and along the wood fibers is allowed for a more even distribution of varnish over the surface. Usually, the product is covered with oil varnish 3 times, to obtain a higher quality - 5-6 times. The first layer (the thickest) is applied with a thick varnish with shading. Before the second coating, the dried layer is sanded with a fine-grained sandpaper along the wood fibers until the surface becomes completely matte. The last (thinnest) layer is applied with diluted varnish strictly along the fibers without shading.

.

In order for the surface to be mirror-smooth, it is polished with a linen swab slightly moistened with alcohol, and along the sole - with oil (this operation is called polishing). The polishing is carried out with quick circular movements so that one trace of the tampon partially overlaps the other and there are no dry spots left. The dried tampon is again moistened with alcohol and oil. The polishing is repeated at short intervals 2-3 times, after which the remaining oil is removed from the surface with a soft cloth and the product is allowed to dry.

Nitro-lacquer coatings are soluble (reversible), colorless, dry quickly (usually in 15-30 minutes), but have limited water resistance. Nitrolacquer is best applied by spraying, but can be applied with a swab or brush if the surface to be varnished is small.

The main difficulty in working with a swab or brush is that the entire surface of the product must be covered with nitro-lacquer in one pass. Re-varnishing is unacceptable, because this softens or even completely dissolves the previously applied and already dried layer of varnish.

By spraying, 2-3 layers of nitro varnish can be applied (with intermediate sanding). Small products are simply dipped for a few seconds in a jar of varnish, then, having been removed, the excess varnish is allowed to drain and the product is hung to dry.

First you need to decide what kind of varnish you need to process the product. Since the product can be used both indoors and outdoors, various varnishes are produced accordingly. After buying a varnish, you must carefully read the instructions for use, then to decide how to apply the varnish on the surface. The first layer of varnish should be thin.

It is better to start with the edges, then work on the surfaces. Lacquer should be applied in uniform stripes, parallel to each other. After the first layer of varnish has dried, the wood fibers will invariably rise again, to remove them, use sanding paper No. 220 or No. 240. This process is called intermediate grinding and is necessary to achieve an almost completely smooth surface. Thus, the required number of layers of varnish is applied to achieve the desired result.

Before opening the surface with varnish, it must be sanded. All movements must be made without effort and along the fibers, because any transverse scratch will be very noticeable after varnishing. For the same purpose, after sanding, the wood must be vacuumed to remove microscopic dust from it.

Lacquer should be applied with a brush or swab. Professionals advise using a tampon. It does not need to be dipped in varnish. It will be correct to pour the varnish inside the swab. In order to evenly apply the varnish, you can use a sprayer. Using this method, the varnish will be more evenly distributed over the surface. In the role of a compressor, you can use a vacuum cleaner.

Lacquer can only open a completely clean and dry wooden surface. The varnish must be applied in several visits after a certain period of time. If you use nitro varnish, apply it at intervals of 5-15 minutes.

If, as a result of staining, you want to get a dark color of wood, the intervals between applying varnish should be increased from several hours to a day. The number of layers of varnish is also important. For example, 4-5 layers will be enough to finish the doors.

If you are using nitrocellulose or alcohol varnish, make sure that the room is well ventilated, and if the product can be taken out, generally outdoors.

You need to work with gloves, because if the varnish gets on the skin, irritation may occur. To avoid this, you can smear your hands with Vaseline and wipe dry. It forms a protective layer on the skin. It is necessary to apply varnish with wide strokes, avoiding passes several times in one place. At the end of the work, excess varnish must be removed. Sanding layers of lacquer is possible only when no trace remains when pressing on the lacquer. For grinding the surface, it is better to use a fine sandpaper with purified kerosene. The first and second layers of varnish can not be sanded. · .

Any wood, even the most resistant to external factors (for example, larch) requires additional processing in the form of a protective layer. As a rule, in this case, a two-pronged task is solved - protecting the material from destruction and decorating the surface.

Preparations are different. Some are processed for the first time, others - repeatedly. We should not forget that the base through the varnish, even if it is dark, will be at least partially visible. Therefore, a preliminary, “rough” cleaning of the surface is carried out if there are any irregularities on it. Although this step is not mandatory.

If the sample that is planned to be varnished needs to preserve its original, artistic appearance, then such work is not carried out. For example, if you want to place a snag, a branch of an interesting, unusual shape, or something similar in the house. There are enough fans to transform the interior in this way.

Drying

Applying varnish to raw wood is an unpromising task. In the process of moisture evaporation, the material is deformed, and wrinkle nets appear on the surface coating in different places.

Crack sealing

If the tree is dry, then it is advisable to seal all cracks. Again, when it is not required to emphasize, highlight this characteristic of him (the author will allow himself to express himself in this way) - antiquity. In other cases it is mandatory. At least in order to exclude the possibility of getting into the cracks of the varnish. Otherwise, the estimated amount of funds will not be enough. On sale there are special putty compositions - for wood - which should be used.

Abrasive treatment

Simply put, fine sandpaper (160 - 320). It will make the wood smooth, therefore, the varnish will lay down in a thinner layer and much more evenly, without smudges and “drops” on the surface. If you're lucky enough to buy the so-called "sanding sponge" - even better. The quality of processing will be the highest. For those who already, there are no problems at all.

Application of primer

Someone, not knowing all the features of wood and varnishes, considers this work a senseless, waste of money and time.

Why is soil needed?

Additional alignment of the base. Even the smallest skin will not provide perfect smoothness. Firstly, the grains are of a certain size, so microscopic stripes on the tree will definitely remain. Visually, this is imperceptible, but after varnishing it can appear. Secondly, you need to make an “amendment” for your own accuracy. To grind the workpiece as much as possible, it will take both patience and time. As a rule, most of us do not have enough of both.
Increasing the strength of the "coupling" of varnish with wood. The fact that any wood is hygroscopic does not mean that the protective (decorative) layer on it will be securely fixed.
Reduced varnish consumption. This does not require explanation. On a perfectly even base, the product lays down in the thinnest layer. Moreover, as a rule, a one-time coating of the tree is sufficient.

What is used

Liquid wax (preferably in cans, in the form of an aerosol). You can cook it yourself by dissolving it in turpentine.
Primers of the KF series. Numbers from 1 and more.
Carpentry glue diluted in water (200 g per liter).
A mixture of wood powder with PVA.
Talc or chalk powder. It is enough to dilute in water, if necessary, add pigment.

Application technology

The number of layers is determined based on the condition of the wood. There is only one recommendation - do not start re-coating until the applied layer is completely absorbed into the tree. Before starting this work, it is necessary to clean the base from the dust that will remain after grinding it.

Lacquering

Its feature depends on the purchased funds. Therefore, in this regard, the main adviser is the recommendation (instruction) of the manufacturer. But a few tips won't hurt.

The acquired composition should be diluted to a liquid consistency, in a proportion of (approximately) 50/50. Such a varnish will spread well, fill all the microscopic cracks, so there will be no traces of the brush, and the layer will turn out to be thin. And this is a reduction in the consumption of coating material. But this nuance concerns only the first layer.
For the second (and subsequent) the ratio is 75/25, that is, the varnish should be somewhat thicker.

When it is applied in several layers, each, after hardening, is sanded again. This will level (smooth out) all the "waves" that may form due to the uneven distribution of the composition over the surface. Naturally, the last (finish) coating is not processed.

To avoid the appearance of the smallest stripes on the surface, it is advisable to varnish the wood with several brushes. Each layer has its own. Why not work with the same one? Even the highest-quality cleaning of the villi from varnish does not guarantee that its smallest particles will not remain on them. And since you have to wait until the applied layer dries, they will harden. As a result, when re-coated - multiple microscopic scratches.

The author draws attention to the fact that the article describes only the technology of varnishing wood. Which composition to choose depending on the type of wood is a question that requires separate consideration. The same applies to tinting agents.

The final result will depend on how correctly the wooden surface is prepared for painting. How can wood be treated before water-based varnish or stain? What are the best tools to use?

The preparatory process before varnishing a wooden surface consists of:

Thorough cleaning of surfaces, removing dust, dirt and old paint from it. This stage is mandatory, otherwise the coating made with varnish or stain will be uneven and will soon begin to collapse.
Applying a protective agent. Which tool is best suited in each case is influenced by the conditions in which the object to be painted will be used.
Primer treatment. This is required to improve the adhesion of the varnish to the wooden surface. For interior work, it is permissible to use only water-based products with a non-toxic composition.

Surface grinding

wood sanding

Work must be carried out in a room that provides optimal conditions for drying the surface. The temperature in the room should be constant, without sudden changes, approximately 20 ° C. There should be no dust and dirt inside, since even the smallest particles of litter can ruin the coating, make it uneven.

Before starting work, you need to prepare all the necessary materials and tools:

a set of sandpaper (fine, medium and coarse-grained);
wooden rectangular block;
a layer of rubber;
stick of small diameter.

All surfaces that are planned to be treated with water-based varnish or stain must be carefully sanded, the resulting wood dust must be collected with a vacuum cleaner, and the surfaces treated with a cloth soaked in solvent.
The painted parts of the tree are pre-treated with an abrasive. First use coarse-grained, then grind the surface with fine-grained paper.

grater for grinding

To simplify the work, a bar is used - it is wrapped with sandpaper and smooth surfaces are treated. In this case, the technology of wood processing should be taken into account: movements should be directed along the fibers so as not to injure the surface.

For bulky areas, rubber is wrapped in sandpaper, and for holes, a stick.

Wood protection products

To prevent the wood from spoiling, it should be treated with impregnation before varnishing or staining.

You need to choose a tool, taking into account several factors: operating conditions (indoors or outdoors), temperature conditions and climatic features.

Antiseptics

Water-based antibacterial impregnations prevent the appearance of mold or fungus on wooden surfaces. Antiseptics have a very toxic composition, so it is not recommended to treat them with products that are planned to be used in a residential area.

Wood protection products

Flame retardants

Such compositions significantly reduce the natural combustibility of wood products, and in the event of a fire, prevent its rapid spread. They are used for surfaces that are located near sources of fire.

Insecticide formulations

They serve as a reliable protection against insects. They are used for processing wooden surfaces on the street, garden furniture and other items that will be outdoors.

Water-repellent impregnations

They are used to protect wood from swelling when wet, cracking and deformation when dried. Means of this type penetrate deep into the wood, filling the pores of the material, and after final drying provide a reliable water-repellent layer.

Such impregnations can be used for surfaces of products operated in wet rooms and outdoors.

Combined funds

Liquids that perform two or more functions, such as insect and mold repellency. They are used when surfaces need to be protected from several potential threats. Consistent use of several tools takes more time and effort, is more expensive, and combined tools in this case are the best choice.

Surface priming

There are ground fluids on various bases.

wood priming

When choosing a primer, it is important to take into account not only the degree of toxicity of the liquid (it is unacceptable to use agents that emit harmful compounds in residential premises), but also its structure. The primer must be compatible with water-based stain or varnish. Otherwise, there is no guarantee that the coating will not start peeling or blistering.

Alkyd

It is recommended to use it in rooms with high humidity or for outdoor work. Most often, it is used to prepare the floor or walls in a bath or sauna before painting. Properties of a primer of this type: filling the pores of wood, protection against swelling of the fibers.

acrylic primer

Its main advantages: the ability to penetrate deeply into the structure of the material, the absence of toxic substances in the composition, quick drying.

Acrylic water-based primers can be supplemented with various components to improve the protective properties. For example, wood pre-treatment liquids can be added to them, in which case there is no need to impregnate the surfaces.

A water-based primer is used for both outdoor and indoor use.
It has an insignificant degree of toxicity, however, it needs thorough and fairly long drying (at a temperature of about 20 C, the surface will dry for about 18 hours). Additional properties of the liquid - protecting the tree from fungus, moisture and decay.

Alkyd primer should be used either in the warm season or under a canopy.

Epoxy primer

Priming fluid, which includes epoxy resins, creates a reliable water-repellent layer on the treated surface. Means of this type are toxic and quick-drying, so they can only be used outdoors. Suitable for areas with high humidity and frequent precipitation.

The use of an epoxy primer requires some experience on the part of the person, as the coating consists of two components that must be mixed just prior to application.

Shellac primer

Such mixtures are used infrequently, since they are intended for processing raw wood. The composition of these primers includes alcohol and other components that accelerate the drying process of wood and reduce its deformation.

After completing these works, the surface of the wood is ready to be coated with a water-based acrylic lacquer or stain.

Careful selection of protection products and the right wood processing technology will help create a durable and durable coating.

Surface treatment with varnish is one of the most common types of wood finishing. Lacquering protects the product from moisture, ultraviolet radiation, mechanical damage, and also makes the texture more interesting. Varnish is used to treat the surface of wooden furniture, decorations, building structures, parts of musical instruments, as well as decorative elements of vehicles.

Material selection

Varnishing wood requires the use of quality materials and tools. Depending on the purpose of the wooden product and the conditions of its operation, it is necessary to use varnishes that are suitable in terms of characteristics.

There are several types of varnishing material:

oil varnishes are made on the basis of synthetic or natural oils, to which special components are added that increase the strength of the coating. Most often, oil varnishes are used indoors for the treatment of walls and floors. The finished coating is transparent, but has a yellowish tint;
alcohol formulations are made by dissolving natural or synthetic resins in alcohol. Alcohol varnishes create a thin coating that is unable to provide high-quality mechanical protection for wood, but at the same time make its top layer more moisture resistant. Very often, such products are used for priming wooden surfaces;
nitrocellulose products obtained by dissolving nitrocellulose in organic solvents. Special additives are introduced into the composition, which can increase the strength of the varnish coating. Nitrocellulose varnishes are applied, as a rule, in several layers;
acrylic varnishes are made on the basis of polymeric acrylic resins. They can be used to create not only transparent, but also colored surfaces. These materials are very durable, environmentally friendly, but their use is possible only indoors;
alkyd varnish materials are made from synthetic resins based on inorganic solvents. The surfaces obtained with these varnishes are highly durable and resistant to moisture. All this makes it possible to use such varnishes to cover the facades of buildings, wooden elements located on the street;
polyurethane compounds based on polymers make it possible to obtain a thin coating resistant to mechanical stress. Very often, such varnishes are used to process musical instruments.

It is possible to varnish the surfaces which are in the street or in rooms. Modern means allow you to protect even wood immersed in water. If there is no varnish, then it is replaced with drying oil or wax mastic, after which the wooden surface becomes slightly velvety to the touch.

Preparation of tools and workplace

For high-quality varnishing of wooden surfaces, you will need working tools.

If you use traditional varnish in jars, then you can not do without brushes. Their size and quantity are chosen depending on the scope of work and the types of varnish used. Preference should be given to natural bristle brushes.

For processing small wooden products, as well as various planks and rods, narrow brushes with a width of 15 to 20 mm can be used.

When processing surfaces of a large area, it is advisable to use flute brushes with a width of 100-150 mm.

Rollers are also used for processing large areas, but unlike flute brushes, they are inconvenient to varnish curved surfaces.

At home, you can varnish the surface with a spray can, but it is more expensive and is used only for small products.

Sandpaper is needed for mechanical cleaning of wooden surfaces and grinding them before varnishing. For processing, it is necessary to have several types of sandpaper of various grain sizes. You will need a brush with which you can sweep away dust from the prepared surface.

The grinder is used if very large surfaces need to be prepared for varnishing. The vacuum cleaner is used to remove dust during grinding, as well as to clean large items.

Having collected all the necessary tools, you need to prepare the room if the work will be carried out inside. It is necessary to take into account the possibility of ventilation, since many compositions of varnishes emit substances harmful to the human body and have a pungent odor.

The room should be bright enough so that you can visually control the result of the work. If necessary, provide the workplace with artificial lighting. If you plan to use power tools, such as grinders or vacuum cleaners, make sure that you have electrical outlets and suitable extension cords in your work area.

Surface preparation

To cover the wood with a layer of varnish, you must first carefully prepare the surface to be treated. The whole result of future work will depend on the quality of such preparation.

It is a mistake to think that under a thick layer of varnish it will be possible to hide small irregularities on the surface of the wood. All defects must be repaired prior to varnishing. An exception may be the case when you need to specifically highlight the texture of the tree and emphasize the relief.

Grinding

A clean planed surface must be sanded with a grit of 80-100.

If the surface was previously coated with paint or varnish, the old coating is removed. This can be done with sandpaper with a grain size of 40-60. It will be very difficult to remove old paint or varnish by hand, so it is better to use a belt sander for such work.

For further processing, you can use a vibrating grinder. The direction of sanding must match the direction of the wood fibers, otherwise the scratches will remain visible even after several layers of transparent colorless varnish.

After grinding, the surface must be thoroughly cleaned of dust. This can be done with a brush or, if the surface is very large, with a vacuum cleaner.

Primer

When using any type of varnish, it is necessary to follow the instructions for its use very carefully. Sometimes manufacturers require that the wooden surface be primed before varnishing. If such a requirement exists, it cannot be neglected, otherwise, when applying varnish, the degree of adhesion may be insufficient, and over time, the varnish surface will begin to peel off and fall off.

The type of primer composition is selected in accordance with the recommendations for the use of varnish.

As a rule, varnish manufacturers also produce related materials - primers, solvents, which are advised to use. Deviation from these recommendations and the use of materials of other brands is possible, but in this case it is necessary to understand the composition of varnishes and primers. It may happen that two compositions are completely incompatible in chemical properties. The results of their interaction can be completely unpredictable.

Varnishing

In order for the varnish coating to last for a long time, not to peel or swell, it is important to follow the application technology.

Varnishing wood is made in several layers. How many of them should be depends on the manufacturer's recommendation and the conditions for using wooden products, but usually at least three are applied - a primer + two undiluted.

Note! To avoid visible streaks, the brush is first moved along the wood fibers. Vertical surfaces are treated with light cross strokes, taking very little varnish.

You have to work quickly and accurately. Then drying is necessary for the time specified in the instructions.

After the first layer has dried, it is necessary to re-sand the surface with 120 grit sandpaper. This will help get rid of unwanted stains that could result from the fact that the tips of the outer wood fibers deformed when wet and then dried.

The polished surface must be cleaned of dust, wiped with a clean damp cloth. After the first layer dries, you can apply the next one.

After applying the second layer, if necessary, the surface is polished, then varnishing is started again. The penultimate layer is sanded with a very fine sandpaper with a grain size of 200 to 400, after which the last, final one is applied. Excess varnish on the edges of the surface during its application can be removed with a swab dipped in solvent.

After applying the last layer, the surface is thoroughly dried. If necessary, the lacquer coating can be polished. Polishing is carried out with felt or felt, using grinders and special polishing pastes. A properly lacquered surface transforms a wooden object, whatever it may be.

A lacquered wooden product is not only beautiful in appearance, it can serve you for a very long time if you make functional demands on it. How to properly varnish a tree, how to prepare a product for this procedure - this instruction will tell.

A good result is determined by the approach

Every business has a first step and a last step. And between them is a labyrinth of possibilities and a huge number of traps for beginners. Varnishing wooden products is no exception, so the analysis of the topic will be serious.

Parsing:

Preparatory stage. This includes the removal of an obsolete coating (if it took place on the product), grinding, repair, priming;
Applying varnish to wood.

We prepare material, take off old clothes

It's good to work with woodwork that hasn't been used yet, but what about wood that has already been covered with something? The answer is unequivocal - to remove the layer or layers that were applied before.

There are several ways to implement the plan:

A layer that clearly moves away from the surface of the tree is removed with a mounting knife, or a flat and sharp object, such as a spatula, is used;

Note! This situation occurs when a wooden product stays outside for a long time, the old coating can peel off, crumble. When removing it, be careful, there are still islands of a tight hitch of wood with paint. Cutting them off can damage the outer wood covering.

Blisters, coatings can be removed with abrasives. Sandpaper is fine for this. At the initial stage, you use a coarse-grained abrasive, closer to completion - zero (this is also about sandpaper), a little later this process will be covered in more detail;
If you are tired of the old coating, or if it was applied with violations of technology, then it is better to remove it completely. Use a household trick.

For your information! Any paint and varnish coating perfectly departs from the wooden frame, if it is pre-ironed with a hot iron, you can of course use a building hair dryer, but not everyone has it. In order to avoid contamination of the soleplate of the iron, this procedure is recommended to be carried out through a newspaper sheet.

Repair and grinding

The need for repair arises when working with old wood, but do not flatter yourself with illusions, chips, cracks, and loss of knot material are also possible on new blanks.

In the presence of such defects, carry out the following complex:

The defect site is cleaned and sanded. Use coarse sandpaper for this. Your task is not to bring the wooden surface to a mirror surface, but to remove chips, burrs, smooth the edges of defects;
A special putty for wood is applied to the defect with a soft spatula;

From the piggy bank! Putties for wood, thanks to multi-colored fillers, actually have the color of any tree, but you just have to choose the one that you need.

Next comes the grinding of the filling. The purpose of this stage is the complete cleaning of the streaks of the filling material, as well as the alignment of the overall surface to a single level. Here, just at the leveling stage, a fine-grained abrasive is used.
that has not been coated with paints and varnishes is processed according to a similar principle. You can use a grinder, but this is justified when the need arises for large amounts of work. For example, you need to sand the parquet flooring in the whole apartment, with sandpaper by hand, of course, this will take a long time.

Grinding

Material	Competent use
Use a bar to which the abrasive is driven	There are special holders for sandpaper. They are much more convenient than bars, the skin of the hands does not come into contact with the abrasive and is not injured.
Using sticks on which abrasive belts are attached to grind holes	We remind you that there are semi-circular and round needle files designed for wood. Very useful on the farm.
The use of a rubber insert on which sandpaper is applied, thus curvilinear surfaces are processed	Sandpaper will do a great job with this problem without rubber inserts.

Primer: One Shot, Multiple Targets

In this section, we will be interested not just in primers, but in combined mixtures that will perform several functions:

Protection of a wooden product from pests and diseases. Antiseptics are not a luxury, but a necessity. This idea sounds in every material - wood is an organic product, rots, requires protection.
Leveling the surface of the product, closing micropores and microdefects, in turn, will reduce the consumption of varnish on wood during painting.

And in terms of species components, we are interested in two groups of goods:

Primers containing wax;
Primers based on adhesives.

Note information! Frankly, all these primers will perfectly cope with the tasks set, they are all applied by hand and they have similar application technologies. The priority characteristic when choosing is the price of the mixture.

Lacquering

This stage is important, it was to it that we led you through thorny paths. Applying varnish to wood has its own characteristics. Therefore, we disassemble everything slowly.

Choice of tools. The better to apply varnish on a tree is not an idle question at all. You can use brushes of different sizes, you can use rollers or spray guns.

Where to stop, how to apply varnish on a tree, consider:

Brushes. These assistants are very useful when working with small products or curved surfaces, as well as for varnishing carved parts. At home, you can use a brush to cover skirting boards, stools, tables, wooden furniture fronts and other household items.

For your information! We will not open America to you, but you can varnish any wooden surface with a brush.

Rollers. A wood varnish roller is justified if it is necessary to varnish a large flat area, for example, wooden panels in an office, or parquet floors in rooms.
Airbrush. It is used in cases where a very large surface is covered, and an even distribution of the material without streaks and gaps is required. This, of course, is the covering of wooden walls on the outside.

Application technique

The spray gun is a useful invention.

How to properly apply varnish on wood - technology in questions and answers:

How to varnish a tree - apply varnish by hand, hold the brush at an angle to the surface;
All foreign objects: brush hairs, dusty large parts, foreign objects require immediate removal. And only then does the leveling process take place;
The consumption of varnish per 1m2 on wood will be 1 liter per 8 - 12 squares. In this error, the main role is played by the issue of preliminary preparation, which we have already described. The better the preparation, the lower the consumption;
How many layers of varnish should be applied to a tree - the answer to a similar question is very clearly shown on advertising palettes in stores. When purchasing a varnish with a stain, you see a picture - what you get at the output when applied twice, three times.

Finally

The question of how to apply varnish to a tree is not as important as the question of how to prepare a tree for painting. The video in this article is ready to give extended information on the process of varnishing wood products.
