Glued laminated timber is a unique building material of its kind. But do not forget that it is almost entirely made of wood. And no matter how such timber is processed in production, upon completion of the construction of the box, it is necessary to take all measures to protect the material from external influences. One solution is to paint a house made of laminated veneer lumber.
Painting a house made of timber is one of the options finishing works. It is appropriate to carry it out if the outer walls are not intended to be insulated, and if the inside is to additionally use any finishing materials, for example, lining, drywall, etc. The complexity of painting is determined by the quality of the laminated veneer lumber, the selected coloring compositions and, of course, with total area walls
We work inside the house
With proper house design and implementation construction work The interior painting of a laminated timber building is purely decorative. The main task is to emphasize the natural beauty of the wooden surface, the secondary task is to protect the walls from possible mechanical damage(eg scratches, etc.). For this you can use:
- the simplest paint and varnish compositions, such as drying oil, special oils and wax. Their role is by no means protection against mold development. But they allow you to fully reveal the beauty of a house made of laminated veneer lumber and give the wood a golden hue;
- wax based mastics. They give the timber a tactile silkiness and make the house more practical: after interior painting In houses made of laminated veneer lumber, walls can be wiped with mastic using a regular rag. Another plus is the camouflage of mechanical defects;
- water-based or synthetic varnishes. They are selected based on the intended purpose of the premises, for example, trains on water based preferred when the presence of the smell of organic solvents is simply unacceptable
We improve and protect the façade of the building
Have you ever wondered why wooden houses lose their attractiveness over time? appearance? This is clearly visible on old log houses of bathhouses or village buildings: the walls gradually become gray - their surface is more porous. All this negatively affects both the aesthetics of the house and its performance characteristics. The reason is quite simple: wood is sensitive to external influences building material, it can even be called living. Therefore, a house, even if it is made of laminated veneer lumber, is not happy to come into contact with a humid environment or direct sunlight. The same ultraviolet radiation causes the destruction of the “cement” of wood, lignin, which binds cellulose fibers together. Moisture leads to the active development of fungi with all the ensuing consequences. As a result of exposure external factors the walls darken, lose their original mechanical properties- the house is destroyed.
To prevent this from happening, it is necessary to create a barrier between the laminated timber and the external environment. This barrier is made up of transparent (glazing) and opaque (covering) compounds applied to the external walls of the house using either ordinary brushes or special paint sprayers.
The use of various compositions allows us to solve two problems:
- protect the house from the negative influence of the external environment. Protection against rotting is provided by antiseptics, and from ultraviolet radiation by special compounds with a UV filter, in other words, opaque or translucent;
- change the appearance of the building in better side. When building a house from such an expensive building material as laminated veneer lumber, not everyone agrees to cover up the beauty of the wooden surface with a layer of paint. Therefore, translucent compositions, oil-based paints, etc. are used. If there are flaws in the wood, then it is better to give preference to painting with covering paint

Exterior painting of a laminated timber house includes:
- surface grinding. Glued laminated timber does not always differ perfectly smooth surface– light sanding allows you to eliminate minor “defects”. In addition, it promotes better adhesion of the applied compounds, because when it is carried out, fresh wood fibers are exposed;
- sealing the ends of the beams. This part of the material is most susceptible to moisture due to high permeability. To reduce the risk of damage to the timber and reduce the consumption of impregnations, it is enough to treat the ends with a special acrylic sealant. It is advisable to carry out this stage of work immediately after erecting the box;
- priming the wall, impregnating the material with an antiseptic. There are compositions that combine the properties of the above, some even contain a UV filter. Their main purpose is to prevent the development of fungi and other wood lovers. Even if the manufacturer claims that its timber is antiseptic, impregnation of the wall will not be superfluous! After applying the primer, you may encounter such an unpleasant phenomenon as pile raising - the wall will become rough. To get rid of lint, you need to sand the surface with fine sandpaper. Once the desired result is achieved, it is necessary to remove the resulting dust;
- applying several layers of paint that defines the appearance of the house. Painting compounds are applied sequentially after the previously applied layer has dried. The optimal number of layers is 3. This applies to both covering and glazing compositions. Before applying a clear coat, make sure that the primer contains a UV filter.
All of the above work is carried out only on a dry surface of the timber at an air temperature of at least 5 degrees Celsius. Naturally, the process does not tolerate rain and snow.
House painting prices
In different companies, the cost of painting services for wooden structures can vary significantly. We have indicated the average price level in the table below. It shows that the prices for sanding a house made of timber are the highest. It is not surprising - this is one of the most labor-intensive processes.
Finally
Even if you are going to build, are building or have already built a house from laminated veneer lumber, do not deprive it of the opportunity to show itself in all its glory. Choose the optimal coloring composition and make it even more beautiful and more protected!
Glued laminated timber has an extremely attractive appearance. Despite this, home owners often decide to paint the material. In most cases, they are guided by two defining motives: the desire to give the house even greater aesthetics and the desire to protect the laminated timber as much as possible from negative impacts factors environment. Painting a house made of laminated veneer lumber can be done both outside and inside the building.
Interior painting work
If the construction of the house was carried out in accordance with the requirements project documentation and compliance necessary technologies, interior painting work is mainly decorative in nature. Painting laminated timber inside the house has two main goals:
- give surfaces an attractive appearance, perform decoration, while emphasizing the natural and natural attractiveness of wood;
- If possible, protect surfaces from all kinds of mechanical defects (scratches, chips, etc.).
As a rule, to perform this type of work the following are used:
- simple paints and varnishes - wax, special oils, drying oil. Their task is to maximize natural attractiveness wooden surfaces, giving them a unique and aesthetic golden and glossy hue;
- wax mastics. Wax-based mastics are excellent for processing laminated veneer lumber. There are several reasons for this:
- giving an original and attractive silky structure to the surface of the material;
- improvement of operational properties - when cleaning the walls are wiped with a regular rag;
- the ability to eliminate visible defects on the surface of laminated timber;
- synthetic or water-based varnishes. They are used if the customer wishes to give the surface of the material shades various colors. Advantages water compositions- no pungent odor, fast drying. Synthetic varnishes, which also have a high drying speed, have the advantage of richer shades and longer service life of the coating.
Now on the market building materials there is a wide range of different varnishes, paints and mastics that are used when painting wooden house from laminated veneer lumber. Anyone can easily choose finishing material, which is most suitable for him, both in terms of properties and performance characteristics, and in cost.
Exterior painting work
When painting laminated veneer lumber from the outside, the ability to give additional protection wooden structures from environmental influences. Painting laminated veneer lumber on the outside has two main objectives:
- protection of house structures from the negative effects of environmental factors. The main ones are:
- rotting, mold and fungi (antiseptic compounds are used to protect against them);
- ultraviolet (translucent or opaque compositions);
- moisture (enters the pores of the wood, mainly through the ends - protection is provided by impregnation of them with special sealants);
- giving the building an aesthetic and attractive appearance, while maintaining, if possible, the organic nature of the wood. For this purpose, translucent compositions are used, various oil paints etc.
Features of painting
Before you start painting a laminated timber house, you should familiarize yourself with the rules and stages of the work:
- sanding walls. Glued laminated timber has a smooth surface, but sanding will clear it of dirt and smooth out microcracks. In addition, sanding improves the adhesion of the base and subsequent coatings, and also gives an attractive appearance to subsequent coatings;
- applying a special sealant to the ends of the bars. Through the ends, moisture mainly enters the pores of the wood, so this stage of work is very important for increasing the service life of structures made of laminated veneer lumber;
- antiseptic treatment of the surface of laminated timber. Antiseptics prevent wood from rotting due to mold or mildew;
- padding. The purpose of the primers used is to increase surface adhesion with subsequent finishing coat. After applying the primer, you need to let it dry;
- painting the walls. Painting walls made of laminated veneer lumber is done in 2-3 layers (usually 3). Each subsequent one is applied only after the previous one has completely dried. The recommended number of layers guarantees an attractive and durable matte or glossy finish, depending on the material chosen;
- 2-3 months after the work is carried out, resealing is carried out. It is accompanied by an inspection of surfaces in order to identify possible defects and their subsequent elimination. Also, the trim and window sills of the house are sealed.
The stages of work are given for external painting of laminated veneer lumber. The sequence of work inside is simpler, but generally the same, with minor adjustments.
External work is carried out at an air temperature not lower than plus 5 degrees and at normal humidity. It is not recommended to carry out work in rain or snow, despite the advertising statements of some manufacturers of paints and varnishes.
Manufacturers of paints and varnishes
Among the variety of paints and varnishes suitable for painting laminated veneer lumber, a number of their manufacturers stand out.
Tikkurila (Finland)
Most famous manufacturer, who has been working successfully for a long time Russian market. In addition to Finnish factories, he recently opened several in Russia. The products are of extremely high quality, wide range and relatively low cost. If there are sufficient financial resources most builders will prefer this particular manufacturer, all other things being equal.
Zobel and Osmo (Germany)
Two German manufacturer, representing the opposite approach to positioning their products. Zobel works in the budget segment, the materials are of high quality, however, they are not leaders in this. Osmo, on the contrary, focuses on wealthy buyers, offering them products at a high price. highest quality and unique characteristics and properties.
Thermika (Russia)
Leading manufacturer among Russian companies in the market segment. The emphasis is on the low cost of products, as a result of which the quality does not always correspond high standards. However, due to the low price, the company remains competitive in the market.
Conclusion
The decision to paint a house made of laminated veneer lumber is made by the owner, mainly, with two main goals: to protect the material from the negative influence of the external environment and to give it an even more attractive appearance, while preserving the beauty and aesthetics of the wood. Proper execution of painting work will not only improve the appearance of the building, but will also extend its service life.
A freshly assembled wooden house looks very attractive, the beauty of the structure natural wood can hardly “improve” even the most modern coatings. But wood has one “unpleasant” quality - over time it changes its color, darkens, various stains may appear on it, etc. In order for your structure to have its original appearance for as long as possible and at the same time not lose the advantages of natural wood, it is necessary paint a house made of laminated veneer lumber and be sure to use only modern paints and varnishes. The house must “breathe” and not emit harmful pollutants into the air. chemical compounds and do not require frequent execution current repairs. Currently, the industry produces such dyes, they completely satisfy all modern requirements. Let's consider the algorithm for performing work, it is common to everyone wooden buildings, and are painted using the same technology.
The number and complexity of the stages depends on the age of the house and its current state. The sooner you apply makeup, the less time and money you will waste.
- Preliminary surface preparation. If on front side there are flaws - they need to be eliminated. Sand, cover with mastic, etc., the choice of method depends on the size and nature of the damage. The most difficult thing is to deal with temporary darkening of wood under the influence of precipitation. Such changes penetrate quite deeply into the wood, eliminating them takes a lot of time and is a very expensive process.
- Primer. Mandatory operation for external walls; indoors may not be performed. For primers, compositions that have high adhesion and with wooden structures, and with finishing varnish coatings. It should be noted that it is varnish that is used in the vast majority of cases; it makes it possible to preserve the “natural pattern” of the walls. Some builders offer to carry out additional processing external walls antiseptics - we consider this an unnecessary operation. Moreover, there are complex protection primer compositions on sale.
- Direct painting of a house made of laminated veneer lumber. The minimum number of layers is two, the next one is applied only after the first one has completely dried. We have already mentioned that they are most often used clear varnishes. But there are cases when it is very difficult to restore the appearance of the timber, then the use of opaque paint is the best option.
- Processing the ends of timber. Be sure to close it before painting decorative boards, applying varnishes or paints directly to the insulation is prohibited. For ordinary laminated veneer lumber, such work is not necessary. You may come across “advice” that the ends should be dealt with later, they should dry. You should not listen to such advice: while you are “drying” the timber, it will crack. Then you will have to seal them, and it is very difficult to do this unnoticed. By the way, the timber is supplied with a specific humidity of no more than 12% and it is especially not worth drying it additionally.
How to paint a house made of laminated veneer lumber
We will not provide a long list of different manufacturers, this is not necessary. We will tell you only about the main groups of paints.
- Glazing paints with antiseptic properties. A clever foreign word means a simple concept - these paints are transparent. Of course, modern paints have much better performance characteristics than their predecessors.
- Covering paints with antiseptic properties. This is a category of opaque dyes, used for painting old houses or by special order of the consumer.
Approximate cost of painting a house made of laminated veneer lumber
Each company sets its own prices; the data provided in the table is for informational purposes only.
It is advisable to comprehensively select paint coatings taking into account their shade properties. If you consult with a designer first, the appearance of your home will only benefit. If you decide to listen to “yourself,” that’s also an option. And then you won’t have to blame anyone. Additionally can be processed end cuts beams, seams between logs and cross-cuts are sealed, stairs, terraces, balconies are painted, conservation is carried out wooden elements etc.
Even the most quality timber without special processing within 1-2 years it begins to turn black or blue. This occurs due to temperature changes, exposure to UV rays and biological factors. Wood turns blue/black especially strongly in the cold season, so it is impossible to leave a house made of timber without painting for the winter. Blue and blackness that appears on wood cannot be removed in any way. It is almost impossible to whiten it, so painting a house made of timber and protecting the wood from negative influence it is necessary to approach it as responsibly and in a timely manner as possible.
- moisture protection and mold prevention;
- bio-protection from insect pests, rodents;
- protection from aggressive environmental factors;
- significant increase in the service life of the structure;
- masking wood flaws, irregularities, defects;
- presentable appearance, updating and changing the style of the house.
Painting a house made of timber can be done both with transparent paints and varnishes, and with colors that fundamentally change the color and appearance of the structure.
How to paint a timber house?
- When choosing what to paint a house made of timber, owners should know the basic requirements for paints and varnishes:
- Resistance to temperature changes - paint or varnish must be adapted to the Russian climate.
- Fire safety - the composition must include fire retardant substances.
- UV resistance - protective covering should not fade or fade for at least 3-5 seasons.
- Vapor permeability - the paintwork should not interfere with air exchange.
- Safety - the product must not be toxic or contain resins or hazardous compounds.
Huge range of paints and varnishes for timber
Today there are more than 500 options for paint and varnish compositions for exterior and interior works. When choosing a product for painting a house made of timber, it is recommended to take into account not only the cost and appearance of the wood after painting, but also such parameters as: consumption, method of application, durability, etc.
Painting a house made of timber: interior painting work
For interior woodwork, safe, non-toxic products are used that dry quickly and are odorless. Such compositions include:
Wax and mastic
Wax perfectly protects the timber from rotting and moisture, and is durable. A significant disadvantage of wax is high price. Timber walls, covered with wax, look presentable and stylish. The velvety texture of the material allows you to mask wood defects and highlight the cut pattern without changing the texture of the wood.
Painting timber with wax
Lucky
Inexpensive decorative material for painting a house made of timber. There are glossy and matte varnishes. The best option- use of both types of varnishes: first, matte and then glossy are applied. A serious disadvantage of varnishes is low vapor permeability; the varnish creates a film on the surface, not allowing the wood to “breathe”. Reduce Negative consequences varnishing will be helped by a well-organized ventilation system. Distinguish the following types varnishes for interior work:
- Acrylic. Environmentally friendly, odorless formulations. Acrylic lacquer — the best option for painting the inside of a log house. The varnish is used to treat walls, furniture and ceilings.
- Alcohol (polishes). Ultra-resistant varnishes that create a durable glossy layer. Used to cover floors and surfaces subject to frequent mechanical stress. Polishes are characterized by low moisture resistance, so they cannot be used for painting verandas, balconies and terraces in a house made of timber.
- Polyurethane. Water-based varnish with high adhesive properties and durability. Excellent for painting the inside of a timber structure, but has a fairly high cost.
- Oily. Considered obsolete and rarely used in modern finishing. They create a durable layer on wood with low vapor permeability. Can be used for floors and ceilings when increased abrasion resistance is required.
Coating with clear acrylic varnish
Antiseptic impregnations and solutions
First of all, antiseptics are designed to protect wood from rotting and moisture. Most formulations contain a small amount of components that enhance the natural color of the timber, giving it a warm tint. There are two types of antiseptics:
- Impregnations. They penetrate deep into the wood structure and are toxic, so they require a safe paint coating to be applied on top.
- Solutions. Created on the surface of the timber protective film. Such solutions are indispensable in rooms with high humidity: baths, bathrooms, saunas, etc.
Paints
Using paint will completely change the color of the wood. Most modern coloring compositions for painting timber inside the house are environmentally friendly products that allow the wood to “breathe” and do not emit toxins. When choosing paint, it is recommended to pay attention not only to the shade, but also to the composition: good paint should not contain formaldehyde and resins. In construction stores for owners timber houses We offer the following types of paints:
- Acrylic. The widest variety of colors, safety, ease of application and durability - all these advantages make acrylic paints on wood is the best option for painting a house made of timber from the inside.
- Oily. Paints on oil based new generation are characterized by high abrasion resistance and give the wood a deep, rich color. The disadvantage of oil-based coloring compositions is a long period drying and low resistance to UV rays. Oil paints are often used in combination with clear varnish.
Painting wooden walls paint
Before applying paints and varnishes, timber bleaching agents are sometimes used to remove dark spots or streaks. Such products are highly toxic and safety precautions must be observed when using them.

Ask a question to an expertEnamels and nitro paints cannot be used to paint the inside of a timber house! These products have extremely low vapor permeability and harm wood, changing its texture and environmental properties.
Painting the outside of a timber house
The external walls of a timber house are coated with special compounds intended for facade works. Painting is carried out only when the moisture content of the timber does not exceed 25%.
To paint the outside of a timber house, natural and synthetic paints and varnishes are used, the most popular of which are:
Varnishes and paints based on polyurethane
They have increased resistance to UV rays and climatic factors. They give wood a beautiful appearance and have a variety of color palette: bleached oak, milk nut, wengei etc.
Painting a house during construction
Water-based paints
Inexpensive and easy to apply formulations that absorb and dry quickly. Require additional waterproofing protection, for example 1-2 layers polyurethane varnish. In the absence of waterproofing, such paints are washed out within 1-2 seasons, and the house requires repainting.
Oil facade paints
Affordable paints that allow you to completely change the color of wood and disguise defects. They have a significant drawback - they are not durable; after 2-3 years, cracks appear on the facade, the color fades, and stains appear.
Alkyd paints
Less susceptible to fading and burning out than water-based and oil-based ones. The main disadvantage is the fairly high cost combined with a low service life of 2-4 years.
Plain alkyd paint combined with bright oil
Acrylic paints
Acrylic compositions for exterior use are quite expensive, but their durability is much higher than that of the above types of paints. Big choice colors and durability make this paint coating option the most popular for painting the exterior of log houses.

How to choose a color for a house made of timber?
The paints offered for timber buildings are matte or glossy. Glossy surfaces certainly look impressive and stylish, but it is worth considering that all wood defects are more noticeable on them: chips, cracks, knots and poor-quality cuts. Matte surfaces are more advantageous in this case. Also from many manufacturers paint coatings There are intermediate options: semi-matte or semi-gloss compositions that combine all the advantages of both types of texture.
In Northern Europe, the most popular option for painting a house made of timber is the following: acrylic or alkyd paint of the selected shade is applied to the facade, and the surface is coated with a durable and wear-resistant varnish. When choosing a paint shade for timber, it is recommended to take into account the advice of experts:
Win-win and classic version- dark and light walnut, mahogany, oak (shades brown wood). Such paints are suitable for houses made in all architectural styles.
Plain cold shades: from white to blue - look beautiful only on well-finished and perfectly smooth timber. These colors go well with bronze, gold or platinum tints.
Combination of blue and white-silver shade
Light wood shades: bleached oak, walnut - are well suited for low and small cottages. However, choosing light color, do not forget that it can only be 1-3 shades lighter than the natural color of the wood, otherwise you will have to renew the paint every season.
Our company offers painting of timber houses with materials that have proven their quality and effectiveness. We use only certified paints and varnishes that meet all operating requirements in the Russian climate.
Technology of painting a house made of timber
Painting a house made of timber is carried out in two ways:
- manually using painting tools;
- mechanized using a spray gun.
When painting a surface with a spray gun, the consumption of paint and varnish material increases by 10-20%, but the paint lays down in a more even layer. The choice of painting method is carried out taking into account the cost and type of coating, weather conditions, area of the timber structure and other factors.
Painting technology includes the following steps:
- Preparing walls for painting: cleaning, sanding, filling cracks.
- Applying primer in 2 layers. The second layer is applied after the first has completely dried.
- Covering the surface with the selected paint and varnish composition taking into account the manufacturer's recommendations.
- Applying the final varnish coating.
As a rule, paint and varnishes are applied in 2-3 layers, with each subsequent layer applied after the previous one has been completely fixed. The process of painting timber should be carried out immediately, without extending it over several days, because... in this case, the tone of the areas will differ. If there is heterogeneity in color, experts use chemical brighteners and pigments.

Ask a question to an expertIf, after completion of construction, you are not ready to paint a house made of timber inside and outside, for example, you have not decided on a color or there is not enough Money, then to prevent the wood from blackening it is necessary to sand it and treat it with a primer. In this case, the timber will not lose its original color for 1 year.
Cost of painting a timber house
The cost of painting a log cottage depends on the type of paint used, the method of application and the area of the building. The best option is when painting the timber is part of the range of services of the company that built the house. The cost of 1 m2 of painting a house made of timber includes:
- preliminary grinding in 1-3 passes;
- preparation of painting tools and scaffolding;
- coating the timber with an antiseptic;
- consumables (rollers, masking tape, etc.);
- painting process;
- garbage collection.
The cost of painting is always calculated individually
Sometimes the price may include paint material. In any case, the price of painting a house made of timber does not exceed 1-5% of its cost and is affordable for everyone. The benefits of properly painted wood will pay for the cost of painting many times over.
After purchasing a house made of laminated veneer lumber, the owner is faced with the question of whether to paint it or not? If you paint, with what means and how to do it correctly? Painting a house made of laminated timber is necessary in the same way as for any wooden one. The only thing is that it is easier to do due to the characteristics of the material.
Despite the use of an adhesive base, the material is breathable and “living”. This means that the surface after construction of a house made of timber is afraid of direct sunlight, moisture and temperature changes. Surface painting with various protective equipment will save the owner from further forced repairs.
For protection, special primers are used - antiseptics, which will prevent the appearance of fungi and mold. And in the second stage, a layer of protection from direct sunlight is applied.
It is also not unimportant how the walls will look, which is why both glazing and matte covering compositions are used.
Products for covering a house made of laminated timber
House made of laminated veneer lumber painted with glazing compounds
There is no point in delaying painting a house made of laminated veneer lumber. You need to paint it right away, and it’s better to soak it with antiseptics for the first time before assembling. Various compositions of domestic and imported production are sold for coating.
But not all of them have the appropriate quality; experts recommend using Osmo, Sikkens (AkzoNobel), Tikkurilla products. If painting is done correctly, it will need to be re-painted no earlier than in 4-5 years.
The qualitative characteristics of some of them can be seen in the table:
| Manufacturers | pros | Minuses | price, rub. |
|---|---|---|---|
| Sikkens (AkzoNobel) (German manufacturer) | They produce a water-based coating that does not fade under direct sun rays, excellent adhesion, Many color options, low cost. | You need to constantly monitor it, because after 5-6 years it begins to peel off. | From 120 l. |
| Osmo (German manufacturer) | There are both water-based and oil-based coatings that do not fade over time, protect the wood from destruction, and are easy to clean. | The price is high | From 320 l. |
| Tikkurila (Finnish production) | An assortment of more than 35 colors, there are formulations based on natural oils and water, does not fade in the sun, and a reasonable price. | It will have to be repainted after 3-4 years. | From 150 l. |
| Marshal (Russia, Moscow) | Low cost, does not fade under the sun, a wide range of paint and varnish coatings. | Not durable, repainting will have to be done every 2-3 years, slight coloring. | From 100 l. |
| Finncolor (Russia, subsidiary of Tikkurila) | Assortment of colors more than 35, many different varieties, including on the water and natural oil, low cost. | You will have to update it every 3-4 years. | From 120 l. |
When choosing a coating composition after completing the construction of a house made of laminated veneer lumber, you need to focus on a number of factors:
- External or inner covering. (Eat universal remedies, which are used both on the street and in the house, but it is better to use separate ones, since the main function of the internal one is decorative, and the external one is protective).
- The appearance of the walls (whether the owner wants to preserve the natural pattern and texture or not).
- What effect do you want to get (protection or enhance beauty, or both at once).
For laminated veneer lumber, two types of coatings are used: film-forming and impregnating.
Impregnating compositions
Impregnation of a house made of laminated veneer lumber
Impregnating antiseptics can be divided according to their composition:
- Water based
- Organic based.
Impregnations - water-based antiseptics do not have a strong odor and easily penetrate the wood. The timber after such coating will not lose its quality characteristics. Water-based impregnations are used mainly indoors.
Organic-based impregnations contain various impurities that help prevent the development of mold and mildew. But they may have a specific smell, so these are mainly for external work.
Coating film compositions
These can be divided into transparent and matte. Transparent ones include glazes, which do not tear off the wood, but only emphasize its texture and pattern. When coating, the shade may change slightly, but this depends on the number of layers applied, the species and the natural color.
Matte ones will hide the appearance of the wood and give the house the chosen color. These are rarely used for laminated veneer lumber, since the material itself has a noble and beautiful surface.
Subtleties of painting a house
All painting takes place in several main stages:
- Sanding the surface of the walls. Even after building a house from profiled timber, the sanded timber must be passed through in one layer with the finest nozzle. During construction, the walls will still get dirty and, without sanding, the paint will not lie evenly.
- Applying a primer is an antiseptic. It will prevent the appearance of mold and fungi and increase the adhesion of paint to the timber.
- Painting. Varnish or paint is applied in several layers. Moreover, each subsequent one is applied only after the previous one has dried.
When painting, it is important to carefully treat the ends of the timber. If the ends are not sealed, moisture will easily penetrate inside through the capillaries. To do this, use all possible sealants, the cheapest of them liquid glass. To enhance the effect, you can tap the ends with a rubber hammer before painting. But you need to be careful, as the slats may come apart.
Before painting, it is important to study the instructions for use and correctly calculate the paint consumption. It is better to purchase a little more, since even from the same manufacturer there may be a slight difference in shade in different batches.
It is not recommended to paint outdoors in damp weather and at temperatures less than +5 degrees. The surface of the timber must be cleaned of dust and sanded. It is not recommended to paint outside in the evening, as dew will ruin the surface.
For processing interior walls They mainly use oils and mastics based on natural oil or water. But they are not sufficient to protect against moisture and dirt, but there are enough of them inside the house. The walls are coated with glossy or matte varnish on top.
If you don’t have the opportunity or skill to paint the walls yourself, then it’s better to turn to specialists.
How much does it cost to paint walls
The cost of painting laminated timber depends on:
- Dimensions of the area to be painted.
- Whether preliminary preparation is necessary or not.
- Work team qualifications.
The average cost for basic work can be seen in the table:
Building a house from laminated veneer lumber is not a cheap pleasure. This means that he must have adequate protection. You need to choose high-quality and expensive coverage.
