How to paint a balcony lined with clapboard. The choice of materials for covering the lining on the balcony. Types of protective varnishes and paints

Lining, like any material, and especially wood, requires special processing in the form of paints and varnishes. So that it does not darken, does not deform under the influence of temperatures and humidity, and serves as an excellent heat-retaining material for a long time, it must be taken care of. Using lining for wall and ceiling cladding on a balcony, it is necessary to take into account the specificity of this room and the responsible mission assigned to it to preserve heat, as well as the possibility of a high level of humidity due to the same, for example, drying clothes.

The choice of paintwork material

Saving all the properties and environmental friendliness of the lining, it is better to use scuba gear as a protective coating on the walls of the balcony, and alkyd varnishes on the floor. After processing with varnishes, the lining will retain its original appearance and wood pattern, darkening will not form on it.

To change the color of the lining in accordance with the interior design, it is better to use water-based semi-gloss paints. After all, it is this type that is most often used for processing wooden and metal surfaces. Average paint consumption per 10 sq. meters equals 1 liter.

Preparing for painting the lining

Do not forget that before painting the lining, it is necessary to clean it from old layers of paint, varnishes or resins. To do this, use acetone, sandpaper, scrapers, a 3% soda solution and other cleaning agents.

Better paint application can be achieved by pre-degreasing the surface after pre-cleaning.
Then the surface will need to be sanded and a primer for wood applied.
This will extend the life of the lining itself and the color of the paint will be more saturated, and the layer will be more durable.
The last step is to wait for the primer to dry completely and start painting with a brush.
The paint is usually applied in two coats for greater stability, but a third can be applied if necessary.
The main thing is that before applying the next, the previous one is completely dry.
It is better to paint from top to bottom to avoid the appearance of streaks.

The aesthetic value of the wooden decoration of the facade of the apartment depends on the correctness of the solution of the problem - “how to paint the lining on the balcony”. The choice of materials implies taking into account the individual characteristics of the situation and finding a balance between the attractiveness, stability of the coating and one's own ideas about beauty and expediency.

The range of materials used for wood processing is wide, which allows you to realize any fantasies. The complexity of the choice lies in the selection of optimal combinations of properties.

Design features of the balcony

If the balcony is well insulated, then it can become a full-fledged living room.

The first condition taken into account when choosing paints and varnishes is to assess the position of the surfaces to be treated - whether they are outside or inside the room. The apparent obviousness of the answer, since the balcony is located behind the outer surface of the wall of the building, can be misleading.

If the balcony space is completely isolated from atmospheric influences by a fencing belt and glazing, then it is permissible to consider it as the interior space of a dwelling and use appropriate materials.

Preservation of the original design, in which the facade wall of the house, the floor of the balcony and the inner part of the fence are exposed to weather factors, which requires a choice from a different range of paint and varnish coatings intended for outdoor use.

Painting lining on an open balcony

If the balcony is open, then you need to choose a paint that is resistant to temperature extremes and humidity.

Painting lining on a balcony, not isolated by external structures from the effects of precipitation and sunlight, should provide long-term protection of the surface from these destructive factors, giving the facade individuality and aesthetics.

Please note that wood is not able to withstand repeated soaking cycles, and is prone to warping and deformation. These properties of the material will inevitably affect the quality of the finish coating, will contribute to its destruction and aging.

Therefore, you should refrain from using the lining for finishing horizontal surfaces and some sections of the walls, which can get water from the balconies located above, cornices, rainwater drainage gutters.

A little about the colors used

As a finishing layer, any paint and varnish materials used for outdoor work are used. These include:

polyurethane;
alkyd;
oil paints and enamels;
water-based latex or acrylic based;
natural and synthetic varnishes;
Separately, we can mention the popular PINOTEX, which is considered the standard of style.

Before painting, the rails must be impregnated with a primer or impregnation.

It is important to take into account that the profile of the lining complicates the coloring in the places of mating of the plates, leaving untreated and weakly colored places, which can become a springboard for biogenic destruction and the initiator of deformation. Therefore, preparatory work during painting, which includes the application of primers or impregnations, is best done before the installation of a decorative shield.

A variety of paints does not allow in a short review to provide exhaustive information about the features of their application, especially since this is not necessary, because each package is accompanied by detailed instructions for use, including recommendations for choosing primers.

Do not save on paint, because a good coating will extend the life of the entire structure

When choosing paint for exterior wooden surfaces, you should not achieve maximum savings. Some manufacturers use cheap raw materials of dubious quality in order to reduce the price of products. With such materials, it is almost impossible to achieve a satisfactory result, and their durability will be far from expected.

antiseptic

Do not neglect the preparatory operations that the paint manufacturer suggests that you perform in the instructions attached to it. It is usually advised to use dry wood, prime the surface, and indicate the number of coats of paint needed to create an effective coating.

You can pre-treat the lining with an antiseptic, although this is not always necessary, some primers and paints contain similar components that inhibit the development of microflora.

Strive to use good paints from trusted manufacturers belonging to global brands. Given the insignificant amount of work, this will not lead to tangible financial costs.

Painting lining in a protected space

Compositions for interior work perform more a decorative function than a protective one.

The balcony closed on all sides allows the finishing coating to work in comfortable, less aggressive conditions. They are close to the internal parameters of the dwelling, differing in greater humidity and temperature changes. Therefore, painting the lining on the balcony is carried out with appropriate materials.

Interior paints are characterized by lower weather resistance, reduced release of aromatic substances, and pronounced aesthetic properties. In composition, they are close to paints and varnishes used outside. The absence of aggressive environmental factors allows you to focus on preserving the texture and appearance of natural wood, which gives the room naturalness and comfort.

Make sure that the air temperature during operation corresponds to the paint, enamel or varnish recommended by the manufacturer.

This will allow you to correctly estimate the drying time of the layers before applying the next one or starting operation. How to paint the lining inside the house, see this video:

Lacquers and paints with low hiding power

Special colorless as well as tinted translucent impregnations on an organic or polymer basis and varnishes are optimally suited to this task. The factor influencing the choice of the type of paint material will be your own idea of the beauty of the surface and the perception of the comfort it creates. How to cover a tree, see this video:
The protective and operational characteristics of varnishes and paints of manufacturers that have proven themselves on the market are close to each other and satisfy the requirements for painting.

Wood under varnish should be smooth, without flaws.

The selection of wood devoid of flaws and defects, the thoroughness of surface treatment, and the accuracy of coloring have a greater influence on the quality of painting the lining on a closed balcony. Particular attention should be paid to these criteria when applying a varnish coating.

This is a rather complicated work that requires understanding and experience, as a result of which it is possible to create an even, deep layer of a transparent coating that pleasantly refracts light and does not create glare for tired eyes.

Lacquer application may require additional manual grinding of the surface, as the visual perception of the hairiness of the material increases.

Most of the owners of balconies choose lining for finishing this room. It attracts with excellent performance and spectacular appearance. However, even such a practical and versatile material under the influence of natural factors can lose its aesthetics and functionality. To prevent this from happening, even at the stage of finishing the loggia, it is necessary to perform a protective treatment of wood. But what to cover the lining on the balcony and what rules should be followed in the process of work, we will consider in this article.

The main reasons why it is necessary to process wood finishing material

Balcony space is characterized by a changeable microclimate. A sharp change in temperature, direct sunlight, dampness - all this inevitably has a negative effect on natural material.

High humidity leads to blue and deformation of the wood, as well as to the formation of mold fungi. With prolonged exposure to ultraviolet rays, the lining (wooden) cracks and may even catch fire. Do not forget about small pests such as bugs, spiders and other insects. Microorganisms, settling in wooden walls, turn solid boards into a pile of dust and sawdust. That is why the question of how to cover the lining in order to ensure its long-term preservation worries many lovers of environmentally friendly materials.

Types of protective coatings

On the modern construction market, there are many chemical compounds that allow you to protect wood cladding from external influences. These include: varnishes, paints, antiseptics and flame retardants. The choice of the optimal option depends on its characteristics and the financial capacity of the buyer. In addition, each composition has certain positive and negative qualities. After reviewing them, you can find the right answer to the question of how to cover the wooden lining on the balcony.

Lucky

Various components can act as the basis of a varnish coating. The functionality and chemical characteristics of a particular protective composition depend on them.

Water-based varnishes. The main advantage of such funds is their environmental friendliness. They do not contain solvents, do not have a strong odor, dry quickly and are completely safe. But water compositions are not able to provide the highest degree of protection for wall cladding, therefore, such lining varnish can only be used on closed balconies.
Acrylic lacquer. Acrylic-based coatings reliably protect wooden lamellas from UV exposure. Such compositions do not contain volatile components, therefore they are safe for the environment. When thinking about how to cover the lining on the balcony, special attention should be paid to these particular means. Processing with acrylic varnish is carried out in two stages: the first layer performs a protective function, and the second gives the material the desired shade.
Alkyd compounds. Lining (wooden) can be coated with alkyd compounds in any premises and in various climatic conditions. The tool forms a protective water-repellent film on the surface, which does not allow moisture to penetrate into the wood structure and protects the material from mechanical damage. However, they are characterized by the presence of a sharp, unpleasant odor and the duration of drying.
These products provide maximum protection for wooden planks. They give wood resistance to frost, moisture and other negative factors. The big disadvantage of such varnishes is that they contain toxic elements that do not allow the use of these coatings indoors.

Impregnation

Wood impregnations reliably protect the material from pests and keep it in its original form. The main feature of this treatment is that the protective agent penetrates deep into the wood structure, where it prevents the growth of bacteria. Stain and wax are used as impregnating compositions.

The first option is considered the simplest and cheapest, but at the same time quite effective. If the lining on the loggia is stained, you can be sure that the material has sufficient fire resistance and will not rot over time. An additional advantage is the ability to give the lamellas the desired shade without the use of paint.

Wax coating allows you to emphasize the natural texture of wood and reliably protect it from moisture. Such processing is optimal in rooms with an unstable climate. The waxing process is certainly long and painstaking, but the end result is definitely worth the effort.

Paints

Before painting the lining with paint, you need to pay attention to the fact that these compounds completely hide the natural pattern of the material. However, when you need to hide a large number of knots or other defects, this option is the best.

Here you can use oil-based formulations. They are perfectly absorbed into the wood and reliably protect it from moisture and other natural phenomena. But before covering the lining, it should be noted that such products dry for a very long time and are not able to retain their original color for a long time.

Acrylic paints are also suitable for these purposes. They do not violate the natural breathable properties of wood and do not change their color over time. Due to its elasticity, the resulting coating is not subject to cracking.

Separately, it should be noted that if direct sunlight hits the loggia throughout the day, then this fact must be taken into account when choosing, the Sunny side contributes to the rapid fading of the finishing material, therefore, in such cases, it is worth giving preference to coatings with UV filters that ensure color fastness on for a long time.

Stages of work

Prior to installation, treat all external and internal surfaces of the cladding with antiseptic solutions.
Leave the boards to dry completely.
Apply the first layer of protective compound.
At the end of installation, apply a finishing (decorative) coating.

Preparing to start work

Before covering the lining on the balcony, you should prepare all the necessary materials and tools. For protective treatment of boards you will need:

antiseptic;
comfortable staircase;
painting tools (brushes, roller, container for solutions);
masking tape;
sandpaper or grinder;
protective mask (respirator).

Surface preparation

If previously used material will be subjected to protective treatment, it must be carefully examined for rot, mold and various defects.

Exposed chips and cracks are polished until the irregularities disappear completely.

When there are dark spots and mold on the surface of the cladding, they are bleached with special compounds. The choice of product depends on the type of wood used. Species such as beech, birch and walnut are disinfected with 12% hydrogen peroxide. For processing ash, a 20% solution of peroxide and ammonia is mixed in a ratio of 10:1. Oak, linden and maple are bleached with oxalic acid, at the rate of 6 ml per 100 ml of water. After bleaching is completed, the product used must be washed off with warm water.

Experienced craftsmen recommend sanding new material as well, since minor flaws appear on it during installation. After grinding, the surface is washed from dust and left to dry completely. Before covering the lining on the balcony with protective compounds, it should be treated with a primer and left for at least a day.

Processing technology

First of all, the border of staining is marked. The strips are glued at the joints of the walls with the floor and ceiling.
The selected coating is poured into a small container, where it is stirred until a uniform color is achieved.
Work starts from one of the corners, gradually moving around the perimeter of the room.
If the treatment is done with a brush, strokes are drawn crosswise so that the composition is well absorbed into the pores of the material.
Working with a roller, the tool is rolled from left to right, and then in the opposite direction.
To avoid a large number of smudges, it is recommended to type the product on the tool in minimal quantities.
After the entire surface has been treated with a protective compound, the grooves of the lining are smeared with a narrow brush.
In cases where the selected product is applied twice, the first layer must be allowed to dry well, and then clean all the roughness with a fine-grained sandpaper.
Next, a second layer is applied. The topcoat must dry for at least two days.

In conclusion, I would like to note that protective compositions should be chosen depending on the type of wood from which the finishing material is made.

For example, if you are thinking about how to cover the linden lining on the balcony, the most correct answer is clear varnish. This type of wood is distinguished by beautiful reliefs and a variety of shades, so you should not hide the natural beauty under opaque compositions. All that needs to be done with such a board is to sand it well and cover it with a colorless varnish.

We examined how to paint the lining, what determines the choice of protective agent, what steps the technology for applying these compositions includes. We hope that the above information will be useful to you, and you will be able to properly perform all the upcoming work, providing the wooden material with a long service life.

One of the most popular types of wooden finishing materials is lining. It has a different profile, thanks to which the surface has a different look - from a smooth wall with small grooves, to waves of different sizes. It's just that wooden walls do not fit into all interiors, so it often becomes necessary to paint the lining inside the room - at home or in the country.

How to process lining inside the house

In general, many people think that it is better not to process the lining inside the premises. Maybe so, but not in every climate and room, it will retain its original appearance for a long time. If the level of ventilation is insufficient, the wood may turn blue; if it is in the sun, it becomes dark gray.

Blueing can only be fought with biological means - chlorine or active oxygen, and after that - unequivocally impregnated with protective compounds, and maybe even painted. With grayed wood, it is a little easier: removing the top layer with the help of grinding, you will again get a beautiful color, but without UV protection, it will also not last long. Therefore, they decide to paint the lining inside the house or cottage.

Another point: not everyone likes wood in the interior. It's just that sometimes people get tired of looking at it. I just want a smooth colored surface. This also happens, and often. In this case, look for opaque paint. Select the characteristic effects as desired.

They paint the lining inside with opaque paints also because wood in natural color is not compatible with all styles. But sometimes you want high-tech, for example. In this case, paint with metallic particles or with mother-of-pearl (for example, Lignovit Platin) is suitable.

All compositions for protecting wood can be fairly roughly divided into six main groups:

Protective compounds. Available for outdoor and indoor use. Exterior compositions additionally include UV protection, which prevents or slows down the process of photoaging of wood - discoloration to gray. So if you need impregnation for lining on the balcony, and it goes south or east, you need a composition for outdoor work. Just pay attention, some of them paint the surface in pink or green color - this is the result of a chemical reaction. Read the description carefully, because it will be possible to paint over the resulting color only with opaque paints or very dark tinting.
Toning compositions or stains. They do not paint over the texture of wood, but give some shade. At the same time, a film is not created on the surface, the wood does not lose its properties - it remains vapor-permeable. Tinting compositions contain pigment and can be lightly or strongly pigmented. If you want to have a surface with a pronounced wood structure, take a slightly pigmented composition. It may take a lot of layers, but you can control the degree of "shading" of wood.
Lucky. Today, for lining on walls or ceilings, water-based varnishes or scuba diving are more popular. They can be matte, semi-matte or glossy. Many have the ability to add color - change the color at the same time. Unlike traditional varnishes, water-based varnishes do not close the pores - the film on the surface remains vapor-permeable, but protects against dirt absorption. Many manufacturers add UV filters and bactericidal components. Such coatings are good for balconies or in unheated rooms with periodic visits - in summer cottages and in baths.
The varnish can be glossy, matte or semi-gloss, and can give color - pigmented
Paints. This group includes compounds that create a dense film on the surface through which the wood structure is not visible. The group is extensive, with different properties and price ranges - from traditional oil to latex and acrylate enamels.
Oils for wood. Some are transparent, some are pigmented. Unlike varnishes, they do not create a dense film on the surface, but are absorbed into the fibers. Good formulations act similarly to varnish, protecting against abrasion and dirt absorption. Only oils do not have a bright glossy sheen - a matte or slightly shiny surface, like silk. This is a great way to save wood. Using a specific application technique with pigmented wood oils, the texture can be accentuated (see below).
Wax based formulations. There are three types of wax: solid, liquid and water. Hard wax is heated to a liquid state before use, liquid and water (wax azure) are already ready for use. Wax protection is traditional and very effective, and new technologies make the process much easier. The disadvantage of wax is that it is quite difficult to apply evenly, but it fits well on a pre-primed surface.

This division is conditional: there are many mixed compositions that can be attributed to at least two groups. So there are impregnations that can be tinted, and there are paints with protective properties. The difference is in the effectiveness of protection. Impregnations primarily protect the wood, and giving color is a secondary task. With colors it's the other way around. Their main task is to create a beautiful coating, and protection is like a side effect. If you need both good protection and a high-quality coating right away, take the impregnation without tinting, and after drying, apply paint.

Another example of a mixed composition is oil and wax. These compositions combine the properties of both oils and wax, so that the wood retains its appearance for a longer time.

The question of which group to give preference to, everyone decides for himself. Different tools solve different problems and it is important to choose the right properties that you need in the first place.

How to paint the lining inside: technology

For painting lining in "dry" rooms inside the house, you can use any type of paint. Here you simply determine the requirements for the decorative appearance of the surface. If the lining is dry, you can not impregnate it with protective compounds, or choose paint / varnish / wax with appropriate additives. You can paint it only on one side, leaving the back side unfinished.

If the lining will be used in damp or unheated rooms, on the balcony, you must first soak it well with protective compounds from all sides, you can do it twice. Only after the impregnation has dried can it be painted, varnished, in general, given decorative properties. Another point: when mounting the lining on a wall or ceiling, it has to be cut into pieces. Places of cuts in wet rooms must also be coated with the composition. It is not necessary to wait until it dries, but it is necessary to process.

There is one very important nuance that many amateur decorators overlook. If you want to get a professional-level lining, you need to process each plank separately: sand, paint, dry, and only then collect the surface from the already painted lining. That is, to mount already fully processed planks on the wall or on the ceiling. Only with this approach, from any point, the surface of the lining will have the same color.

It is difficult to paint the entire surface of the wall upholstered with clapboard.

If you paint an already assembled surface, unpainted places remain in the grooves and recesses, it is difficult to grind large areas. You can't get a perfectly flat surface. The quality of the finish in this version is not above average. It is permissible to paint the finished surface if you are updating the painting. This must be done at different intervals - it depends on the operating conditions and the properties of the paintwork material.

Correctly, the painting technology is as follows.

There can be many layers: it depends on the hiding power of the paint and on what effect you want to get. But in any case, the rule remains the same: there should be little composition on the brush. The exception is impregnations or primers. They are applied with a well-moistened brush, but only those that are without pigment. When applying pigmented protective compounds, the rules for paints apply - the minimum required amount of the composition is well shaded.

Sometimes, even with careful rubbing of the paint, spots are clearly visible. This is not a bad paint, but the properties of wood: somewhere the pores absorb better, somewhere worse. In order to achieve an even color in this case, the surface is first primed. You can use any primer on wood or a colorless matte varnish (you can water-based). After drying, the surface is sanded (yeah, again) and then the required number of layers of paint is applied. Only in this case, after the first layer of coatings, grinding is rarely required, and if necessary, then in some places, more often - on a spike or groove.

How to evenly apply azure, oil or wax, see the video.

If furniture quality of painting is needed, there are even more layers: first, a stain is applied, then two layers of primer. After drying, it is polished to a completely dull surface, first with a grain of 280, then 320, after removing the dust, a finishing layer is applied - varnish. An example of such work in the video.

Painting wood while preserving texture

A pronounced woody pattern can be achieved using azure, pigmented oil or wax. These compositions lie quite tightly, almost painting over the structure of wood fibers. Any of the compositions described above can be applied by brush or roller.

When applying paintwork materials, they take quite a bit, first applying fragments along the entire length of the lining. Then, with a brush or roller, the applied strokes are shaded over the entire surface. After leaving them to soak for 5-10 minutes, a soft, lint-free cloth is taken to reveal the texture and most of the oil is removed. As a result, the pattern appears much brighter than in its original state: a greater amount of pigmented agent is retained in the grooves, and almost none of it remains on the protruding parts. The result is a pronounced texture. This technique is also called brushing or texturing the lining. In interiors, wood treated in this way looks very decorative: both on the walls and on the ceiling.

The process can be seen in the video. Three samples were stained: two with the same oil with a pigment, one with a colorless one. 5 minutes after painting, one of the pigmented blanks was wiped off to develop the pattern. To preserve the wood after the pigment has dried (24 hours or more, read on the package), the lining is covered with two layers of colorless oil (azure, wax). In places of intensive use, it can also be varnished - matte.

How to paint a lining under bleached oak

Often it is required to paint the tree white, but so that the veins are visible. They also say - to create the effect of bleached oak. There are several ways:

It is difficult to say which composition to choose - you need to try. It is advisable to paint the lining with several compositions and compare the result. The effect is slightly different when using different products, but still depends heavily on the wood. The reviews are also very different - someone whitened with tints, someone with oil. Soils are rarely used for these purposes, but mainly due to the fact that not everyone knows their properties.

Secrets of decorative wood staining: techniques and tricks

Residents of cities want to preserve the natural color of wood to the maximum. For those for whom the wood in the house is a boring everyday life, paint the lining inside the premises in some unusual color. Modern coatings allow you to achieve different effects. For example, textured or brushed lining, but in two colors. This technique is often used.

Brushed lining in two colors is an excellent choice for decorating walls

The trick is to apply two layers of different colors. The first layer is applied some dark color, the second - light or brighter. After playing with colors and the order of their application, you can create your own version. Watch the video - how to get a lining brushed in two colors.

Coloring in two colors may not be the same. You can make recesses of a darker color, and the face (front part) is only slightly tinted or everything is done exactly the opposite. It will turn out a striped wall from the lining - the effect of a lath wall.

How to paint lining inside the house: ideas

Painting techniques and methods are great, but how? Just. There are many interesting options. The latest finds of designers - a wall of lining in a room with smooth walls. Looks creative and interesting. And most often such a wall is made using the technique of brushing.

An interesting effect is obtained by combining inserts of different thicknesses - in the photo, thin boards are inserted between wide boards. And they are painted in different shades of the same color. The combination is interesting and fresh.

Lining is not necessarily just a flat board with small grooves on one side, which is also called eurolining. There are different profiles, including those with waves and troughs. From them you can assemble interesting walls, the relief of which is emphasized by coloring.

Interesting reliefs can be assembled from lining of different profiles. To make it look more interesting - emphasize the reliefs or whiten

As usual in the interior, a lot depends on the light. A few non-standardly designed lamps - long translucent strips behind which lamps are hidden, installed in the middle of the ceiling - and the interior is completely transformed. In this design, you can decorate rooms for young people, creative rooms, etc.

You can play not only with light, but also with color: in the lighting zone, paint the lining in a lighter color, emphasizing this zone in this way.

If you have good drawing skills, you can paint the lining. Just do not forget to then cover the whole picture with colorless oil or varnish - so that it lasts longer. This approach can be used when

The living room, hallway look great rigidly defined panels from the lining. In the same vein, you can decorate the wall in the dining area in the kitchen. Only its quality and color should be perfect.

The honey shade of the lining is repeated on the ceiling

Deliberately imperfect may be processing for the interior in the style of "rustic". Such rooms with a masculine character.

Rustic style will appeal to men. In this case, painting the lining using the brushing technique is the norm. And the colors are chosen dark

As if in contrast - light walls. The lining is whitewashed, and the beams are painted dark. Despite the traditional materials used for centuries, the look of such a room is modern and stylish.

An excellent combination is light walls with the effect of bleached oak and dark massive beams. It's practically a win-win.

Lining is also used in the decoration of bathrooms. Impregnation here needs to be given maximum attention, but if done at a level, impregnation is protected from moisture, then there should be no problems. And the interior, you see, is very interesting - the warm tones of wood combined with bright marble are a great move.

Used lining and when. Only it is necessary to fill it horizontally - this way you can expand a small space. And light colors look better in such a small area, maybe with a dark border.

Ceiling - lining, painted with light stain

On the balcony.

There are many options for this. Detailed information on how to properly perform this procedure is given below.

You need to use personal protective equipment:

Rubber gloves.
Glasses.
Respiratory protection.

At this stage, it is necessary to make calculations for individual control parameters:

Evaluation of the scope of work. Measurement is taken over the entire area of the surface to be painted. Depending on the parameters obtained, the required amount is calculated. The average consumption varies between 100-150 g / m2, although due to the density of the surface to be painted, the final figure may differ from the calculated one.
Selection of the necessary material. It is preferable to use alkyd or acrylic compounds. Drying, they create a high-strength protective film on the surface.
Color selection. If the coloring must preserve the structure of the wood, it is preferable to use transparent varnishes of various shades. To obtain a smooth, uniform surface, it is better to use paint.
Surface cleaning. Be sure to carefully clean the surface to be painted from dirt, resin, remove mechanical inclusions. For difficult dirt, you need to use special cleaning agents.
Filling in irregularities. To eliminate surface defects, chips, cracks, etc. it needs to be plastered. Color does not matter if the surface is being prepared for painting. Putty is applied in small portions to the damaged area and leveled with a spatula. Excess should be removed immediately. Please note that these materials are not used for interior decoration of the bath.
Grinding. After the applied composition has dried, the surface is polished. Grinding allows you to achieve a perfectly even coating. To do this, use sandpaper with a grain size of no larger than P240. Work can be done manually and using surface grinders. Careful grinding allows you to achieve a perfectly smooth surface. And this will certainly have a positive effect on the final result.
Dust removal. The dust remaining after grinding should be removed. This is easy to do with a soft bristle brush. The best way to get rid of dust is with a vacuum cleaner.

You can prime the surface for painting with any acrylic or alkyd compound. The primer is applied evenly, in a thin layer. After that, it must dry. This usually takes from 2 to 12 hours, depending on the type of materials.

Consider some useful tips from professionals:

Never try to blow off dust by mouth or use compressed air to blow it off. Small sawdust can get into the eyes, and this is fraught with serious injury.
Always stock up on paint. And try to buy materials in one place and from one batch. Remember that the same one, released by the same manufacturer, but at different times, may differ in color.
If there are dark spots on the surface of the wood, they must be removed. For this, the product is additionally treated with special bleaching compounds and an antiseptic. This will not only kill the fungus on the already infected area of the board, but also protect the neighboring ones from infection. Treatment with an antiseptic composition slows down the oxidation process, this will further increase the life of the tree.
After installation, the surface should be re-sanded if mechanical damage appeared on it during work.

Coloring

The color of the lining on the balcony can be chosen arbitrarily. Coloring is done using the following tools:

Brushes.
roller.
Airbrush.

After the first coat of paint has dried, the surface should be inspected. Existing irregularities, protrusions, paint streaks are sanded, after which a second layer is applied. If necessary, this can be done a third time.

Before use, the varnish or paint must be thoroughly mixed to obtain a uniform tone. It is best to carry out painting work in warm, calm weather, but without bright sun. This promotes even drying.

Please read the handling instructions before using any material! Observe the safety regulations! Lacquers and paints are highly flammable. Do not use open fire near the workplace.

Air exchange and vapor permeability

The ability to pass steam and air is an important property for a room. This is a guarantee that it will not be stuffy or damp. However, for a balcony trimmed with clapboard, these circumstances are not very important. Some experts recommend using yacht varnish for lining on the balcony. In winter, no one lives there, flowers do not grow, the windows are usually hermetically sealed.

Heated balconies are an exception. But here this problem should be considered in a complex, since the layer insulating from the street, in addition to sheathing from the board, also contains a layer of vapor barrier and. In any case, even the boards of the lining perfectly fitted to each other leave gaps between themselves, they themselves are covered with an airtight composition.
