Painting home from multilayer timber from the outside, many are considered superfluous. And, in fact, the high-quality walls made of wood blanks look simply amazing, and this beauty simply “does not raise a hand”.
However, if you leave everything as it is, after a couple of years, not a trace of all the splendor remained. Due to this, houses from a bar of wood must, if not be painted, then at least treated with specialized compositions for protection.
When it is required painting home from multilayer timber from the outside?
- First of all, the main task of paintwork is to increase the attractiveness of the insulated surface. In the case of a wall made of wood, you can easily emphasize the natural beauty of the material, since the cut of wood looks quite beautiful even without it.
- The tree darkens after a certain time, and over time, its texture will have to be veiled. For this purpose, compositions with a higher hiding power are used, which allow hiding the pattern on the surface.
- Paint compositions, impregnations and mastics make it possible to protect wood from adverse environmental influences. The time of preservation of natural beauty depends on the level of protection.
- It should also be said that the prevention of contact of wood with microbes and moisture is favorably reflected in its working properties: a well-painted house keeps its own load-bearing capacity for a long time and does not lend itself to decay.
- Another factor that has a bad effect on the condition of the timber is UV radiation. UV filters help protect you from it, and specifically the substances that are part of many of today's paints.
As you can see, the benefit of painting a house from multilayer timber from the outside, there are many reasons. Now it is necessary to decide on the type of painting and the best technology for its application.
What to choose for coloring?
Internal formulations
The main purpose of interior paint is to give wood walls an aesthetic appearance. The largest protection is required in the middle of the house, thanks to this we advise you to focus not on the decorations.
In the role of materials that can be used to decorate the timber walls in the middle, experts recommend using:
- Impregnating compounds - waxes, drying oils, wood oils, etc. All these funds do not form films on wooden surfaces, due to which the appearance of the wall is almost permanent. At the same time, the texture of real wood and the contrast of the fibers are emphasized.
- Mastics - protect the velvety surface, and also set off the pattern on the saw cut of the bar. In addition, mastic allows you to disguise small cracks and chips.
- Varnishes (glossy and matte) are the most popular compositions that are used for interior decoration. In most cases, a varnish with a tinting element is applied to the base, and then several translucent layers are applied. Typically, the surface is given additional "depth". The varnish is primarily useful where the wall of the timber is most exposed to friction, for example, along the stairs.
- Decorative paints. Painting the tree in the middle of the house can be made with compositions with different hiding power - obeying what the actual task is before them. If you have a desire to preserve the natural pattern of the tree, then use acrylic glazing compounds. If it is necessary to give the wall a new shade, then an alkyd or acrylic-based opaque paint is used.
Almost the same paints and varnishes are used to decorate all kinds of wood elements in the middle of the house. The same way, painting imitation of timber or sheathing from a sheathing board in the middle of the room can be done with the same acrylic varnishes or paints as the treatment of the timber.
Painting home from multilayer timber from the outside: varnishes, paints and impregnations
External processing of multilayer beams, first of all, is aimed at protecting the house from the influence of negative aspects of the environment, and also at changing its appearance.
Analysis of the compositions used for finishing:
- Organic or water based impregnations. As such, they are not considered paints, as they have little or no effect on the appearance of a home. Their important function is to kill germs, protect against fire, etc.
- Film-forming compositions (can be both opaque and translucent). They protect the wood from contact with moisture, while not interfering with the evaporation of liquid from the thickness of the wood.
- Coloring antiseptics - compositions that are intended for exterior decoration of houses from a bar.
- External paints. In terms of properties, they are close to film-forming compositions, however, their main function is considered to change the color of the surface. Though painting houses from a bar from the outside with the use of paints from well-known manufacturers often replaces the protective finish.
Demanded facade paints of houses from multilayer timber
Houses from multilayer timber they look very pretty, but from year to year their appearance deteriorates. This happens under the negative influence of the external environment. Decorative painting allows you to help solve this problem. Literate painting walls includes a set of actions, which we will discuss below.
The color of the coating is selected in strict accordance with the decision of the designer of the house. Contrasting toning will set off the natural pattern and accentuate the woody structure. Paints will give the walls juiciness and cover the tree. But the final selection always depends on the residents of the house. Whatever color you choose for the house from multilayer timber, it must meet the basic requirements.
- The company from Germany "Zobel". Paints of this brand are made on the basis of water, which means they are distinguished by their great environmental friendliness. They are comfortably applied to the base made of wood; this material retains heat for a very long time. Paints and varnishes are shown in a rich assortment. The cost is in the middle range. A serious disadvantage is the need to constantly change the coverage (every 5 years).
- The company from germany "osmo". The material is based on oils, thanks to this, it does not harm human health. Highlights the woody texture very well and is very easy to apply. Keeps the original shade for a long time, does not ask for permanent change. It is often used for external and internal work. Its main disadvantage is an unreasonably high price.
- The company from finland "tikkurila". It must be stated right away that the paints of this company are demonstrated in a rich assortment. Among the positive qualities, it is necessary to note a low price, great color stability and a pleasant color, of the minuses - the need for continuous change - about once every five years.
- Our company "finn color". Paints are offered in a rich assortment and at a minimal cost. For a long time, they cherish their own original color, but they ask for constant touch-up (at least 1 time in 5 years).
- Our thermal paints. The coatings are distinguished by their high resistance to temperature extremes, the influence of ultraviolet rays and moisture, and are best suited for painting houses from multilayer timber from the outside. The prices are quite adequate, but the choice is not happy.
Painting the walls multilayer timber from the outside
Thorough preparation is the key to a good result.
Multilayer timber Is a material with ideal performance characteristics. It almost does not change its initial shape during shrinkage, and yet it is necessary to process or paint it with a different version only if certain rules are strictly followed.
Attention! Experts recommend starting work no later than three months after the construction of the buildings. If you let the house stand for a longer time, then slowly bar will collapse under the influence of climatic conditions, which will be poorly reflected on the adhesion of paint to wood.
For high-quality surface preparation for painted work, here are the instructions:
- Painting is carried out at a temperature of at least +5 degrees. As for work inside, the humidity must be less than 80%.
- To improve the adhesion of the paint to the surface of the timber, all painted surfaces must be plastered and sanded.
Attention! After sanding, you need to "walk" along the walls using an industrial vacuum cleaner. The joints of the beams deserve special attention, since a large amount of very small sawdust, and also wood dust, accumulates there.
- We apply a specialized sealant to the ends of the beams.
- Priming the sanded surface. In most cases, the price of primer formulations is low, but they provide a high quality paint adhesion. Thanks to this, it is better to fork out for a primer, and save on buying expensive enamel or acrylic compounds.
- You can apply paint only after the primer is completely dry.
As for the technology of interior and exterior decoration of walls from a bar, it practically does not differ in anything. Only one difference is in the number of layers of material that is applied to the substrate.
If you are planning to paint with your own hands, follow these tips:
- The paints must be mixed according to the manufacturer's instructions. The situation is similar with varnishes with tinting elements.
- Prepare a clean, large container for mixing.
- Before starting work, test the composition by applying it on a small area. Likewise, you will get an idea of the appearance of the wall.
Attention! It is imperative to do this, since your own wood painting has the maximum effect on the final result. Thanks to this, the test painting allows you to make adjustments and, perhaps, increase or decrease the amount of pigment.
- For painting we use a roller, brush or spray. It is recommended to apply varnishing with a brush.
- First of all, we apply the first layer of material to the wood flooring. The less its thickness becomes, the better.
- After it has dried, we will continue painting. For the decoration of timber walls, 3 to 5 layers of material may be required. They are all applied exclusively at the end of the drying of the previous one.
Upon completion of painting, you must wait until the walls are dry. After 1-2 months, it is worth carefully inspecting the surfaces, and, if necessary, seal the detected cracks and cracks with a sealant. Apply paint on top of the sealant using the same technique as for painting at home.
A couple of tips for painting a house from multilayer timber from the outside
To paint the facade of a wooden house, you need to make preparations and adhere to separate rules. We will provide specific recommendations below.
- Before painting, the surface must be carefully cleaned from dirt and dust with a brush. This work is best done using water. To do this, use a garden sprayer and a brush of average hardness, which will comfortably remove dirt from the surface.
- Get rid of mold with specialized solutions. There are too many of them on sale. To find mold, simply scan the surfaces of the walls for gray-blue spots.
- To get rid of the tree resin, you need to take a metal spatula. Once you remove the resin, there is only a small hole left of it, which can be repaired with varnish.
- If nails or other metal elements stick out of the surface, they should be treated with compounds that prevent corrosion.
- After completing all the preparatory measures, the tree is allowed to dry. This process takes about 2 weeks. To protect the material, you will need to cover the structure with a polyethylene-based film, in which ventilation holes are provided.
How much does it cost to paint a house out of multilayer timber?
Undoubtedly, you can paint the house on your own, having studied our material and familiarized yourself with the photo, but this will take a lot of time and effort, especially if you have a large country house. Thanks to this, many people still resort to the services of specialists.
The cost of wall painting from a multilayer bar depends on the following factors:
- The prices of the materials used;
- Workers' professionalism;
- Type of work required.
The average price of painting services in our country, we want to present to you in the form of a table.

The desire to decorate, and still secure your own house, built from multilayer timber, fully proven. A building of this type will be expensive, which means it will be built for a long time. In addition, decor and wall painting will add personality to your home and express your fantasies and dreams. You have to agree, this is very important!
Conclusion
Internal and external painting houses from a bar are considered a prerequisite if you have a desire to give the building longevity. Ignoring the fact that multilayer timber it is painted over very easily, it is necessary to adhere to individual tips. In this case, the paints will have to be renewed less often, and the appearance of the house will be better.
After purchasing or building a wooden house from a bar, the owner must take care of protecting the external walls from the negative effects of the environment and preserving the attractive appearance of the building for many years. The problem is easily solved by applying a multi-layer protective coating. Simple, at first glance, works have their own technological features, so we will figure out how and what to cover a house from a bar outside.
Painted wooden houses are reliably protected from external influences and look attractive
Features of the harmful effects of the environment
The outer surface of logs or beams is exposed to many destructive factors:
Humidity. Under the influence of rain and snow, wood, swelling, cracks, loses strength, thermal insulation properties. Carpenter beetles penetrate the cracks, dirt accumulates, and mold forms. Even on a smoothly planed surface, after repeated wetting, wood fibers rise, ugly stains and stains appear. The walls take on a messy look. Various hydrophobic paints, oils and impregnations protect the surface from these troubles.
Sunlight. Under its influence, the surface layer of the tree changes color, and then begins to deteriorate. At least the southern wall of the building should be additionally coated with photoresistant, light and UV resistant substances.
Biogenic effects. Various insects, woodworms, fungus and mold can quickly destroy wooden walls. In this case, impregnation and paint with insecticidal and antibacterial properties are used.
Untreated timber collapses, becomes moldy and looks unkempt
If possible, you will have to take into account the totality of all harmful influences and, on this basis, agree with the contractor a list of all necessary work and materials. Only after discussing these issues can a final decision be made than to paint a house from a bar outside.
The outer surfaces of the new building should be treated and painted no later than several months after the end of construction. Otherwise, they will quickly lose their aesthetically pleasing appearance. An exception is painting the house from glued laminated timber outside, it can be done earlier, since this material does not undergo such strong shrinkage.
Varieties of coloring compositions for outdoor use
All surface treatment materials can be divided into two main classes: impregnations and paints.
Impregnation
Impregnations are compounds that, when applied, penetrate deep enough into the wood. Their use allows you to solve several problems at once:
Preparation for painting wood in a given color tone.
The impregnation partially fills wood pores, cracks and surface irregularities. This will reduce the consumption of paint or varnish during subsequent application, which saves money.
Some paints have poor adhesion to wood. The preliminary application of the impregnation strengthens the bond of the paint with the surface to be treated.
Protection against insects, pests, mold and mildew.
Impregnation with an antiseptic will prevent the formation of mold, fungi
Giving wood fireproof properties.
Reducing the harmful effects of the ultraviolet component of sunlight.
Each specific brand of impregnation has a set of necessary qualities. Therefore, it is necessary to discuss with the contractors the required parameters of the composition used and the estimated cost.
Outdoor paints and varnishes
The main characteristics of paints and varnishes are the type, color, durability. The service life of the paint is determined by its resistance to moisture, sunlight, temperature extremes.
If the surface of the wall looks good, has no roughness or defects, then it is best to use transparent or translucent varnishes or paints.
Such compositions include:
Varnishes and paints based on polymeric polyurethane. They have good resistance to external factors. Their high cost is due to the durability and high strength of the coating.
Water based paints. They are quite cheap, absorb quickly and dry quickly. Unfortunately, without additional protection from water with a waterproofing layer, such paints quickly become stained, dripped, and sometimes simply washed out from the wall surface. It is preferable to use them for the treatment of interior walls.
On our website you can familiarize yourself with the most popular projects of wooden houses from construction companies presented at the exhibition of houses "Low-rise Country".
A variety of shades of paints and varnishes allows you to choose a composition for every taste
Old and sometimes new walls have defects, stains, cracks. It is difficult and expensive to make such a surface uniform in texture. In this situation, opaque paints must be used. In this case, you will be faced with the question: in what color to paint the pulp from a bar - the choice of colors and textures is very large.
Oil paints. Due to their low cost and availability, they are still popular. The main disadvantage is that after 2-3 years such paint cracks and fades. The walls that have lost their attractiveness will have to be re-painted.
Alkyd-based formulations less prone to fading. Alkyd paints are available in a rich color palette. The main problem is low resistance to weathering.
Acrylic paints and varnishes will last longer than alkyd or oil. Manufacturers offer a large number of colors and shades of this type of paint. Acrylic paint for outdoor beams has a higher price, but this is more than pays off with the greater strength and durability of the coating.
A separate type of materials for processing is sealants and paint for the ends of the timber. Replacing them with other compounds is undesirable.
The main stages of painting
Knowing how to paint a house from a bar outside, and the technological sequence of operations, will allow you to properly control the entire process.
The quality of painting a wooden house depends on adherence to technology at all stages of work
On our site you can find contacts of construction companies that offer the service of finishing and insulation of houses. You can communicate directly with representatives by visiting the Low-Rise Country exhibition of houses.
Preparation for painting
The surface of the timber must be free of dirt or old paint residues.
Using plows, scrapers, electric planers, they remove significant irregularities, roughness, tar stains or layers of old paint. The use of a metal brush can achieve good results and high productivity.
Large cracks, holes from knots and wood pests are carefully putty. It is possible to proceed to grinding and polishing only after the putty has completely set and hardened.
Wood sanding. This operation is carried out using a grinding machine in several stages. First, use coarse sandpaper. For the final sanding, the emery grain is reduced.
Polishing will smooth out the fibers remaining after grinding, giving the surface a gloss.
Be sure to check whether the ends have been sanded and processed with mastic. This will prevent cracking and moisture penetration into the most vulnerable area of the timber.
Sanding is an important preparation stage before painting at home
During such work, a large amount of dust is generated.
Important! Before applying impregnating and coloring solutions, the settled dust and dirt must be removed.
Surface cleaning can be done with compressed air or special detergents. Please note that the use of detergents will moisten the surface of the walls. Before applying the impregnation, it is necessary to wait a few days until they are completely dry.
Impregnation and painting
Do not insist on carrying out work during rain and fog. Wet wood swells, does not absorb paint well, which leads to flaking and cracks in the coating.
Do not paint external surfaces at negative temperatures.A test check should be carried out before the main painting. Ask to paint a small area of the surface and make sure you are happy with the result. The examples of painting wooden houses in the photo are one thing, but it is worth seeing how the paint will lay on the tree of your house.
The choice of methods for applying the compositions remains with the performer:
Painting by hand. The work is carried out with a paint brush. If the wall is flat, a paint roller can be used. This method will provide the best surface finish, but will require a significant investment of time and effort.
Spray painting reduces material consumption
Using spray guns and spray guns significantly speeds up work, reduces paint consumption. With a large surface area and time limit, you should choose this type of paint and varnish application.
A bona fide contractor will apply multiple coats of primer and paint. This will increase the time to complete the work, but will ensure its high quality. And in order not to be mistaken in choosing a contractor, you need to check his work when meeting him. The distinguished company always has a portfolio with photos of painted wooden houses outside.
You cannot drag out the tinting work at home for a significant period, breaking them into stages. After a few weeks or months, the previously painted parts of the wall may differ significantly in color or shade from the freshly painted ones.

Painting a house made of profiled or glued beams
Profiled and glued laminated timber has a high cost, which is associated with the complexity of its manufacture and good quality. Therefore, painting the outside of a log house made of such materials has some peculiarities.
The stages of grinding and polishing are less laborious due to the initially smooth surface of this type of bar.
Antiseptic treatment should be done as quickly as possible. Otherwise, the outer layer may discolor due to mildew, mildew or exposure to sunlight.
It is most correct to cover the timber with impregnation already during the construction process. It is advisable to apply an antiseptic and refractory impregnation even before laying the timber in the frame.
Primer application is a mandatory operation when working with laminated veneer lumber. Paint or varnish binds more firmly to the primed surface.
It is desirable to paint a house made of laminated veneer lumber with varnish, oil or acrylic paints. Do not use water-based colors, as glued laminated timber does not absorb water well, and stains and streaks may appear.
Video description
You can get acquainted with expert advice on how to paint a wooden house made of laminated veneer lumber in the video:
Painting is done in several layers. Wait until the previous one is completely dry before applying the next coat. In this case, colorless varnishes and paints are preferable, since they reveal the beauty and depth of the wood texture.
Cost of work and paintwork
The price of painting a house depends on many factors: the quality of the surface, the timing and amount of work.
The cost of processing 1 sq. m. surface when performing basic operations:
surface grinding - from 50 to 100 rubles;
antiseptic application - from 50 to 80 rubles;
processing of ends (grinding, priming, painting) - about 250-300 rubles;
varnishing (one layer) - from 100 to 150 rubles;
painting with oil paint - from 100 to 200 rubles;
oil impregnation - 100 rubles.
If the choice of coating color is determined by the owner of the house, then the quality and type of impregnations and paints and varnishes should be definitely discussed with experienced professionals.
An easily explainable desire to save money by buying a cheap paint can turn into high expenses in 2-3 years. A cheap coating quickly begins to flake off, crack, and quickly fade.
The lower price threshold for paints is 100–150 rubles per liter. Service life - up to 3 years.
High-quality paints and varnishes have a price of 300 rubles or more. They retain their properties for 5-6 years.
It should be borne in mind that a low price, all other things being equal, means a shorter service life of the coating, and, therefore, additional costs for a new repainting of the facade.
Conclusion
The owners of a wooden house should take a responsible approach to solving color issues. Timely and correctly executed painting of the walls of a log house will not only delight with the beautiful appearance of the walls, but also increase the life expectancy of the structure.
Glued laminated timber is a unique building material. But do not forget that almost all of it consists of wood. And no matter how such a bar is processed in production, upon completion of the construction of the box, all measures must be taken to protect the material from external influences. One of the solutions is to paint the house from laminated veneer lumber.
Painting a house from a bar is one of the options for finishing work. It is appropriate to carry it out if the outer walls are not supposed to be insulated, but inside - in addition to use any finishing materials, for example, lining, drywall, etc. The complexity of painting is determined by the quality of laminated veneer lumber, the selected coloring compositions and, of course, the total area of the walls.
We work inside the house
With the correct design of the house and carrying out construction work, the interior painting of a building made of laminated veneer lumber pursues an exclusively decorative character. 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 (for example, scratches, etc.). To do this, you can use:
- the simplest paints and varnishes, such as drying oil, special oils and wax. Their role is not at all to protect against the development of mold. But they allow you to fully reveal the beauty of a house made of laminated veneer lumber, give the wood a golden hue;
- wax-based mastics. They give the timber a tactilely silky feel, make the house more practical: after the interior of the house is painted from laminated veneer lumber with mastics, the walls can be wiped off with a regular rag. Another plus is the masking of mechanical defects;
- water-based or synthetic varnishes. They are selected based on the intended purpose of the room, for example, water-based formulations are preferred when the smell of organic solvents is simply unacceptable
We refine and protect the facade of the building
Have you ever wondered why wooden houses lose their attractive appearance over time? This is clearly visible on old log cabins of baths or village buildings: the walls gradually turn gray - their surface is more porous. All this negatively affects both the aesthetics of the house and its operational characteristics. The reason is quite simple: wood is a building material sensitive to external influences, it can even be called alive. Therefore, the house, even if made of laminated veneer lumber, is not happy with contact with a humid environment, direct sunlight. The same ultraviolet light is the cause of 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 the influence of external factors, the walls darken, lose their original mechanical properties - the house collapses.
To prevent this from happening, it is necessary to create a barrier between the laminated veneer lumber and the external environment. This barrier is transparent (glazing) and opaque (opaque) compounds applied to the outer walls of the house using both ordinary brushes and special paint sprayers.
The use of different formulations allows you to solve two problems:
- protect the house from the negative effects of the external environment. Protection against decay are antiseptics, from ultraviolet radiation - special formulations with a UV filter, in other words, opaque or translucent;
- change the appearance of the building for the better. When building a house from such an expensive building material as laminated veneer lumber, not everyone agrees to cover 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 opaque paint.

Exterior painting of a laminated veneer lumber house includes:
- surface grinding. Glued laminated timber is not always distinguished by a perfectly smooth surface - light grinding allows you to eliminate minor "defects". In addition, it contributes to better adhesion of the applied compositions, because when it is carried out, fresh wood fibers are exposed;
- sealing the ends of the timber. This part of the material is most susceptible to moisture due to its 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 the construction of the box;
- priming the wall, impregnating the material with an antiseptic. There are formulations 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 his timber is antiseptic, impregnating the wall will not be superfluous! After applying the primer, you may encounter such an unpleasant phenomenon as raising the pile - the wall will become rough. To get rid of the lint, sand the surface with fine sandpaper. Upon reaching the desired result, it is necessary to remove the resulting dust;
- applying several layers of paint that defines the appearance of the house. The coloring compositions 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 the clear coat, care must be taken to ensure that the primer contains a UV filter.
All of the above works are carried out only on a dry surface of a bar 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 differ significantly. We have indicated the average price level in the table below. It can be seen from it that the prices for polishing a house from a bar are the highest. It is not surprising - this is one of the most laborious 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, homeowners often decide to paint the material. In most cases, they are guided by two defining motives: the desire to make the house even more aesthetically pleasing and the desire to maximally protect glued laminated timber from the negative effects of environmental factors. Painting a house made of laminated veneer lumber can be done both outside and inside the building.
Interior painting works
If the construction of the house was carried out in accordance with the requirements of the project documentation and the observance of the necessary technologies, the internal painting work is mainly of a decorative nature. Painting laminated veneer lumber inside the house has two main goals:
- to give surfaces an attractive look, decorate, while emphasizing the natural and natural attractiveness of wood;
- if possible, protect the 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 reveal the natural attractiveness of wooden surfaces to the maximum, giving them a unique and aesthetic golden and glossy shade;
- wax mastics. Wax-based mastics are excellent for glued laminated timber. There are several reasons for this:
- imparting 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 in the surface of laminated veneer lumber;
- synthetic or water-based varnishes. They are used at the request of the customer to give the surface of the material shades of various colors. The advantages of aqueous formulations are the absence of a pungent odor, drying speed. With synthetic varnishes, even with a high drying rate, there are advantages in the richness of shades and the durability of the coating.
Now on the building materials market there is a wide range of various varnishes, paints and mastics, which are used when painting a wooden house from glued beams. Anyone can easily choose the finishing material that is most suitable for him, both in terms of properties and performance, and cost.
Outdoor painting works
When painting glued laminated timber from the outside, it becomes more important to give additional protection to wooden structures from environmental influences. Outside painting of laminated veneer lumber pursues two main tasks:
- protection of house structures from the negative effects of environmental factors. The main ones are:
- decay, mold and fungi (antiseptic compounds are used to protect against them);
- ultraviolet (translucent or opaque compounds are used to protect against ultraviolet rays from the sun);
- moisture (gets into the pores of the wood, mainly through the ends - their impregnation with special sealants serves as protection);
- giving the building an aesthetic and attractive appearance, while preserving, if possible, the organic nature of the wood. For this, translucent compositions, various oil paints, etc. are used.
Features of painting
Before you start painting a glued beam house, you should familiarize yourself with the rules and stages of work:
- sanding walls. Glued laminated timber has an even surface, but grinding will clean it of dirt and even out microcracks. In addition, sanding improves the adhesion of the substrate 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, mainly moisture gets into the pores of the wood, therefore this stage of work is very important to increase the service life of laminated veneer lumber structures;
- antiseptic treatment of laminated veneer lumber surface. Antiseptics prevent wood from rotting, by the phenomenon of mold or mildew;
- padding. The task of the primers used is to increase the adhesion of the surface with the subsequent topcoat. After applying the primer, let it dry;
- painting of walls. Walls made of laminated veneer lumber are painted in 2-3 layers (more often - 3). Each next is applied only after the previous one has completely dried. The recommended number of coats guarantees an attractive and durable matt or glossy surface, depending on the material chosen;
- after 2-3 months from the date of work, re-sealing is carried out. It is accompanied by inspection of surfaces in order to identify possible defects and their subsequent elimination. Also, at the same time, platbands and window sills of the house are sealed.
Stages of work are given for external painting of glued laminated timber. The workflow inside is simpler, but generally the same, with minor adjustments.
Outdoor work is carried out at an air temperature of at least 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
From the variety of paints and varnishes suitable for painting laminated veneer lumber, a number of their manufacturers stand out.
Tikkurila (Finland)
The most famous manufacturer that has been successfully operating on the Russian market for a long time. In addition to Finnish factories, not so long ago he opened several in Russia. The products are of extremely high quality, wide assortment and relatively low cost. Given sufficient financial resources, most builders will prefer this particular manufacturer, all other things being equal.
Zobel and Osmo (Germany)
Two German manufacturers 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.

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 effects of the external environment and make it even more attractive, while maintaining the beauty and aesthetics of wood. Competent execution of painting work will not only improve the appearance of the building, but also extend its service life.
We treat the stage of professional painting of the house with the same responsibility as the construction of the foundation or the assembly of the walls. This stage includes a large amount of work, and the final result greatly affects the operational and aesthetic characteristics of the house. The amount of expenses for current home repairs in the future depends on the quality of painting.
We have prepared a detailed material so that you can evaluate the dyeing technology in our company, compare with other options and decide which one is right for you.
Color matching
Sixth step: polishing the coating
To achieve a perfectly uniform coating both visually and by touch, we coat it with Festool-Surfix polishing oil and run it with a Festool ITS vibration-inertia machine with a felt disc.
Grinding and painting the ends
Painting of the ends in a glued laminated timber house is carried out individually, often after the walls have been painted. At a certain stage, uneven shrinkage occurs on the outer and inner sides of the timber, which causes deformation of the gap at the points of contact along the profile. Therefore, you can start painting the ends after the most significant shrinkage of the timber has passed, taking into account the seasonality and time of supplying heating to the house. From such important nuances that are accumulated with experience, the final quality and appearance of the painting of glued beams and ends are formed.
The technology for painting the ends is insignificant, but still differs from painting the walls. The end part of the laminated veneer lumber is more porous than the wall surface, so more consumables are needed. It is also very important to properly grind the ends so that depressions and drops do not form along the entire plane of the end. The work is carried out only by qualified specialists with experience in performing exactly these works using quality Festool equipment.
Removing resin pockets and imperfections by sanding is performed in the same way as for preparing the sidewalls of the walls.
Painting the visible rafter system
We paint the open visible roof truss system in the production hall. The rafter system painting technology includes all stages of painting a house: rough grinding, troubleshooting, putty, finishing sanding and applying several layers of oil. Watch our video on how painting works.
Painting window and door frames
Platbands for windows and doors are painted in the selected color in the painting chamber at the factory. There is a constant temperature and humidity level, and there is no dust - this is how we achieve high quality painting products.
Painting lining and planken for hemming overhangs and cornices
The frontal board, lining for hemming overhangs and cornices are polished and painted also in the paint shop in production, observing the necessary conditions for high quality.
Influence of color on the protective properties of the coating
When choosing a color and painting technology, it is important to take into account that dark-colored walls in summer on the sunny side heat up to 80 ℃. If visible resin pockets have not been removed before painting, they will begin to show through. Resin pockets on light-colored walls show through less than on dark-colored walls, but in general the color does not solve the problem with them.
The result of professional painting of houses made of laminated veneer lumber
The consistent implementation of all stages of professional painting leads us to the ideal planned result:
- Colors are exactly matched.
- The entire surface is painted evenly, without stains or streaks.
- The natural texture of the wood has been preserved.
- The painted surface is visually attractive and pleasant to the touch.
- Glued laminated timber is protected from environmental factors.
- The service life of the protective layer due to compliance with the technology reaches 7-9 years. This is 2-3 times the real life of most paints.
- Partial repair of the painted surface is possible - the boundaries of application will not be noticeable.
- To renew the entire coating, it is not required to completely grind it off, it is enough to clean it from dirt.
