Processing a wooden house, how to process a wooden house. Treatment of wooden walls with protective compounds The best way to impregnate the outside of a wooden house

Hello, dear readers. Our article today is unusual in its own way: it will not be brief, but detailed; in it we will sequentially analyze all the stages of processing a new wooden house, so to speak, from “A” to “Z”. So, we present to your attention an algorithm for the step-by-step processing of a wooden house.

Wood processing before construction begins

Treatment of a wooden house with an antiseptic begins, oddly enough, not after the completion of construction work, but during the construction process: the logs and boards intended for the construction of the building will be in the fresh air for some time, which means they must be protected for this period. For this purpose, antiseptics are used, the validity period of which can vary: from two to eight months. The wood can be processed by the manufacturer, but it can also be “raw”: you need to check this with the supplier. An important point: do not store wood used for construction on the ground - no matter how well it is processed, moisture and mold will not spare it. The optimal storage option is on stands/substrates that prevent the wood from coming into contact with the ground.

Treatment of wood with various impregnations: should you trust suppliers?

Many companies involved in the supply of timber for wooden house construction offer potential clients a seemingly win-win option: timber that is fully prepared for the construction of a wooden structure. Of course, the benefits are obvious, but is it worth it to so thoughtlessly trust sellers of wooden structures? We in no way want to denigrate them, but we still advise: agree only to salt impregnation of the timber, which to a certain extent protects the wood from rotting and fire (do-it-yourself salt impregnation is absolutely ineffective if you do not have the opportunity to do this in a vacuum installation or salt the beams in a solution), but it is quite possible to do the treatment of wooden elements with fire retardant, antifungal and other impregnations yourself. Thus, you will 100 percent control the quality of the processing of the walls of a wooden house.

Treatment of seams and facades of a wooden house

Treating the outside of a wooden house is not as easy as some might think. Wood needs maximum protection, so we do not recommend saving on sealing compounds. The most vulnerable areas of the external walls of a wooden house are the crown joints and end cuts, so special attention should be paid to their protection. Acrylic sealants for wood have proven themselves to be excellent, characterized by good indicators of waterproofing, moisture permeability, and tolerance to factors of biological aggression (mold, mildew, insects). And most importantly! The low cost of domestic sealants organically coincides with their high quality: for example, wood sealant Accent-136 is not only recognized by builders as the best material from this line, but is also moderately priced.

Naturally, not only the seams, but also the outside walls of the house need to be reliably protected. If you want your home to look “originally Russian,” use wood oil. This composition is quite durable, reliably protects wood from all atmospheric influences (UV rays, rain, snow, etc.), and emphasizes the structure of the tree. Treating a wooden house with oil, which, by the way, is perfect for both exterior and interior work, will give you the opportunity not to worry about the restoration of the structure for 8-10 years.

Processing the base of a wooden house made of timber or logs

The technology for constructing wooden houses assumes the presence of a waterproofing layer between the foundation and the log house itself, which is roofing felt. Theoretically, it is quite enough to protect the building from moisture, but in practice everything is far from being so rosy. Very often, owners of wooden houses are faced with the fact that a year or two after the completion of construction, a gap appears between the foundation and the log house. It can be eliminated in various ways, using polyurethane foam, caulk, cement mortar, but the most reliable and least labor-intensive option is to use wood sealants.

Fire protection treatment of a wooden house inside and outside

We all understand that of all the negative factors, wood is most susceptible to the influence of fire, and the most dangerous influence - fast and powerful. Internal and external treatment of a wooden house against fire is your second step, after you have repeatedly and finally treated all surfaces with an antiseptic (remember that the first time you need to impregnate the logs/beams with an antiseptic composition so that they do not rot during storage). Fire-retardant impregnation should be used within a certain period of time after treatment with an antiseptic (about 2 weeks), so that one substance, having reacted with another, does not mutually deteriorate the quality of the impregnation. Fire- and bio-retardant impregnation of wooden houses is very important, so you definitely shouldn’t skimp on them worth it, especially since treatment with protective compounds is carried out once and is effective for a long time.

Treatment of a wooden house from beetles, mold, fungus

Internal and external treatment of a wooden house must necessarily include the use of impregnations that protect the wood from biological factors. Wooden structures are a “tidbit” for all kinds of insect pests, mold, and mildew, so if you don’t want your home to “get sick,” use special protective primers and impregnations. High-quality acrylic compositions, both imported and domestic, can be safely used not only for exterior work, but also for treating the interior walls of a wooden house.

Treatment of wooden floors and walls inside the house

A wooden house is valuable precisely because wood creates a unique microclimate in the room, maintains humidity at an optimal level, and saturates the air with its aroma. Therefore, the natural task of the owner of a log house is to preserve the natural beauty of wooden surfaces. Thanks to the availability of high-quality finishing materials on the modern construction market, such as oil solutions, oil with added wax, oil glaze, etc., it is possible not only to reliably protect the internal walls, floors and ceilings of the house from various negative factors, but also to emphasize the structure wood, making its natural relief more pronounced. By the way, wood oil for interior work may not be ordinary, but colored, so it can be used as a decorative element.

And, of course, do not forget that the internal crown seams also need to be treated. Using wood sealant (transparent, colored, matching the walls), you will reliably protect the premises from moisture, drafts, mold: your home will remain warm and cozy in any bad weather.

A wide range of construction and finishing materials is used. Wood and composites based on it occupy a fairly large place in this list. The scope of application is wide: load-bearing and enclosing structures, walls, ceilings, rafter systems, finished and rough floors and much more.

Comprehensive protection of a wooden house and its individual elements is aimed at protecting against the destructive effects of the following factors:

constant and variable mechanical loads;
biological pests, bacteriological and fungal infections;
fires and fires;
high humidity.

The development of a detailed plan of protective measures is carried out at the stage of design work and calculations. The main document regulating the use of wood and its processing materials in construction is SNiP II-25-80. This regulatory act applies to the construction of new buildings, as well as the reconstruction and repair of buildings and structures.

Building structures are subject to significant mechanical loads. The task of designers is to take into account all possible factors. When carrying out calculations, the minimum required cross-section of lumber is determined: timber, beams, boards and slats. Coniferous and deciduous wood, which has different characteristics, is used in construction. This circumstance must also be taken into account in the calculations.

The durability of buildings made of wood or individual elements is achieved through the use of special design solutions. So, to protect the walls in the lower part from moisture penetration, the foundation is waterproofed. Waterproof materials are laid along the upper edge of the plinth - usually roofing felt or roofing felt. As an additional measure: logs and beams are treated with special antiseptic compounds.

Waterproofing the foundation of a wooden house

Reliable protection of a wooden house from the outside is necessary from two main factors - precipitation and sunlight. When rain or melt water hits the desired surfaces of the wall, it can be absorbed or flow into cracks or gaps between the constituent elements. Freezing of water at low temperatures leads to gradual destruction of the material. There are two main ways to protect against these factors:

application of paint and varnish coatings;
the use of so-called ventilated facade systems.

The appearance of the house depends on the quality of the wood used; the use of transparent varnish allows you to preserve the unique pattern of natural wood.

The process of varnishing a wooden house

Plastic or metal siding reliably protects the outer surface of the house wall from moisture and sunlight. Such systems, among other things, make it possible to additionally insulate the building from the outside and use less expensive types of wood. High-quality siding has a long service life and does not require periodic maintenance, with the exception of washing with plain water.

Measures to protect wooden structures from moisture

Wood has a heterogeneous structure and is able to absorb a certain amount of water. A damp surface allows dust and spores of fungi or microorganisms to settle. The breeding ground for them is the wood itself, which gradually softens and collapses. Foci of fungal infections usually occur in the crowns and in the lower part of the walls. Microorganisms are dangerous to the health of people living in the house.

In this video you can see how the lower logs of a wooden house are protected.

Protecting wooden structures from moisture is a rather difficult task. Its solution lies on several levels. First of all, it is necessary to exclude the possibility of water getting on the tree, for which waterproofing work is carried out. The structures are erected in such a way that they are not exposed to precipitation. In winter, snow is removed from wooden walls and brick plinths.

Effective measures to protect against moisture penetration are painting wood with paints and varnishes, and impregnating it with drying oil.

Walls, floors and other structures are treated with aseptic compounds that prevent the fixation and development of microorganisms. The problem of ensuring the safety of wooden structures is directly related to the need for protection from other damaging factors.

Protection from biological pests

Wood is one of the materials of natural origin. Living tissue serves as a source of nutrition for many types of insects and their larvae, as well as various kinds of fungi and microorganisms. Lumber with high humidity above 20%, that has not undergone primary processing and those that have been stored in improper conditions are especially susceptible to infection.

Wood should be purchased from specialized enterprises and carefully inspected to ensure that it is not damaged by fungal infections and insects.

The best quality is lumber that was harvested in winter and was properly dried. Under natural conditions, under sheds or in closed warehouses, this process lasts about one year.

Drying can be accelerated in special chambers, where moisture is removed faster under the influence of elevated temperatures. As additional measures of protection against bark beetles and other pests, special substances are used - insecticides. Chemicals can be used in the lumber production process, during construction work and to treat existing buildings.

Paint and varnish coatings – drying oil and other materials – show high efficiency in protecting wood from insects and fungi. Application of the compositions is carried out in different ways: with a brush, a construction roller or a spray gun. The last method is the most convenient and fastest. When treating walls and other structures, personal protective equipment for the eyes, respiratory system and skin should be used.

spray treatment of wooden walls and house structures

As a preventive measure, it is important to exclude the possibility of moisture getting on the wooden elements of the building. This is achieved by using special design solutions. In places of contact with the foundation, high-quality waterproofing is done, and the crowns are carefully adjusted.

Failure to take measures to protect wood from biological pests can have extremely unpleasant consequences. The presence of fungal infections in wood can negatively affect the health of the inhabitants of the house and the safety of the structure. Beetles and their larvae make branched passages in the massif, which weaken supporting, enclosing and load-bearing building structures. This can ultimately lead to their collapse.

Protection of houses and structures from fires

The main enemy of dry wood is fire. Possible causes of fires are short circuits in electrical wiring, malfunctions in heating devices and careless handling of fire. All preventive operations to protect wood from fires can be divided into two groups:

technical events;
processing with special compounds.

In a wooden house, it is necessary to use only high-quality cable and wire products. To avoid overheating, the wiring cross-section is calculated based on the maximum possible current values. Laying of networks is carried out in polymer cable ducts, metal pipes or corrugations. A fashionable method is to install “antique” open wiring using porcelain insulators.

Combined. Combined impregnations are compositions that protect wood from various factors, for example, from fire and various bacteria, from water and the formation of harmful fungi. In places where humidity is high and the risk of wood contamination is very high, such impregnation is very useful.

Impregnation selection criteria

In order to choose a specific protective solution, consider some nuances. For example, if you choose a water-based impregnation, then you will need additional drying of the wood, which will lead to its deformation.

Use antiseptic impregnations, which are water-based, to treat the linings under the purlins and the purlins themselves; you can also paint partition panels, joists and beams, beams. In this way, you can process elementary lightweight structures that will not deform or bend, and which will not cause much harm or damage.

Oily compounds and oils for impregnating wood have an unpleasant, persistent odor that is quite difficult to erode, and therefore it is better not to use these wood impregnations for internal processing of wooden structures. In addition, all oil solutions ignite very quickly, releasing toxins into the air. Once you have treated the wood with oil, it will become impossible to work, paint or process. Therefore, oil impregnations are only suitable for wooden parts and elements that are located outdoors and are regularly in contact with water.

You should choose an antiseptic impregnation for wood taking into account the specific type of wood, since different types have varying degrees of resistance to various biological destroyers:

- “weak” wood is aspen, linden, alder;

Low-resistant wood - oak, birch and beech sapwood, elm heartwood and maple;

Medium-resistant wood - fir, spruce, larch, cedar sapwood;

Rot-resistant wood – ash, pine, oak heartwood and larch.

Different types of wood absorb certain protective compounds differently, and this should be taken into account when making the final choice of impregnation. Three main groups of wood can be distinguished based on the difficulty of absorbing impregnation:

Difficult - spruce, ash, oak and beech;

Medium - linden, pine core, alder, aspen, maple sapwood;

Lightweight – beech, pine sapwood and birch.

The nuances of do-it-yourself impregnation at home

The price of wood impregnation will depend on its purpose and composition, but you can save a lot and prepare a simple protective impregnation for. In this case, impregnation will be much cheaper than a budget purchase option.

The basis for do-it-yourself impregnation is bitumen.

Impregnation preparation process:

Pour bitumen into an unused old metal bucket or container.
Place the bucket on the fire and bring the bitumen to a boil.
Remove the bucket from the heat and, while stirring, pour in diesel fuel in a thin stream so that the mixture does not have time to thicken even after it has cooled.

In order to prepare a quick-drying impregnation, dilute the bitumen not with diesel fuel, but with gasoline. But in this case, do not heat the composition - the bitumen should completely dissolve in gasoline. After treating wood with this solution, it can be safely painted, coated with various enamels and primed. But under no circumstances use nitro varnishes and paints!

Precautionary measures

Impregnation for a wooden house outside and inside, fire retardant and antiseptic, contain dangerous chemical additives and substances that can... That is why during the processing process, remember your safety measures, and strictly follow the instructions from the manufacturer. Before you buy impregnation, carefully study the information about the degree of toxicity of the composition and its possible use and application inside the house.

Impregnation for wood is a necessary and important protective measure in modern repairs and construction.. Regardless of the hazardous chemicals contained in the impregnation, it can significantly increase the service life of all buildings and ensure safety from fires and various atmospheric phenomena. Good luck!

A wooden house is an environmentally friendly and safe housing that will never lose popularity. Natural wood does not emit toxic hazardous substances, has a pleasant forest aroma and promotes rapid oxygen exchange. In such a house there is always fresh air, a comfortable environment and a cozy atmosphere.

The logs are easy to lay, which reduces installation time. Due to their light weight, they do not require a deep, expensive foundation. And thanks to the natural beauty and aesthetics of the materials, serious and expensive finishing is not required.

However, wooden houses also have a significant disadvantage. Wood is a natural material that is subject to negative environmental influences. Sun rays, moisture and precipitation, insects lead to the fact that the material gradually darkens and collapses. Mold, cracks and fungus appear, and the structure loses its original appearance. To avoid these problems, it is necessary to treat the log house inside and outside using various means.

Why do you need to treat the outside of the log house?

Protects wood from destruction;
Retains the original appearance of a bathhouse or log house for a long time;
Prevents the appearance of fungus and rot;
Prevents insects and moisture;
Increases the service life of a wooden house or bathhouse;
Improves the aesthetic qualities of logs; if necessary, you can change the appearance of the facade, obtain the desired color, shade or shine;
Fire retardant treatment is mandatory for a log house, since fire is a significant threat to wood.

Which means to choose

Today the market offers a lot of products for treating a log house outside and inside. It is important that they are environmentally friendly and preserve the natural properties of wood. In addition, the products must perform the protective functions of the tree from moisture, insects and other negative factors. Decorative properties are also of great importance. There are four main groups of products that will be needed to treat the outside of the house:

Antiseptics are deeply absorbed into the wood, increasing the resistance of logs to moisture and microbes. Antiseptic agents include wax, protective varnish and oils. They destroy mold and blue stains.
Fire retardants prevent the spread of fire. At elevated temperatures, the composition of the product comes out of the log and forms a protective film. Such products prevent instant ignition and resist open fire for several hours.
Preservative solutions and impregnations keep wood in good condition. Special impregnating materials maintain the smoothness and evenness of the surface and prevent the appearance of cracks. And film-forming compounds also create a water-repellent barrier. Primer or wood oils are suitable for these purposes.
Protective and finishing agents are mainly intended for decorating wood. These are paints and varnishes for wood. They protect the wooden surface from fading and dirt. There are also special bleaching compounds that will prevent the wood from darkening over time.

Do not choose one product that will immediately protect against mold and rot, insects and fire, while also performing decorative functions. Practice proves that such impregnations are not very effective. To achieve high-quality and durable results, it is better to use fire retardants, antiseptics and decorative paints and varnishes separately.

How to properly treat the outside of a log house

For the first time, the log house is treated with antiseptics inside and outside immediately after assembly. Pay special attention to processing the ends and logs in contact with the foundation. Antiseptics are applied in two layers;
Primary treatment should not be carried out at temperatures below 10-12 degrees!;
The next treatment is done after the log has completely dried and the frame has shrunk. This takes 6-12 months. This finishing involves the final complex and multi-layer processing of the house, which will ensure long-term protection of the log. It is important to apply antiseptics to a dry and clean wood surface!;
Before processing, the logs are sanded to remove the top layer in which fungus and microbes have accumulated during shrinkage. It will remove defects in the log and level the surface. Sanding wooden walls is a must for an old house, as it is important to completely remove the previous coating;

Processing with a brush will take a lot of time, but it will be of the highest quality, effective and durable. To speed up the process, spray guns are used. But for processing ends, corners and hard-to-reach places, take only a brush;
First of all, antiseptic agents are applied in two or three layers. After drying, the wood is treated with fire retardants in one or two layers and also left to dry. The next layer is primer. It will protect the wood from cracks and level the walls;
Carefully process the ends. These parts of the logs absorb moisture faster than others and are therefore more susceptible to rotting. To avoid this, each end treatment is done in 4-5 layers;
The final stage is a decorative coating that will preserve the appearance of the house and protect the surface from sunlight. With the help of colored paints and varnishes, a certain color or shade, matte or glossy shine is achieved. If you want to preserve the natural color of the wood, use transparent paints and varnishes.

What and how to paint the outside of a log house

Painting is the final stage of processing a log house outside and inside. Today there are a lot of different paints and varnishes. For exterior painting, choose rough and durable compounds. Let's consider the popular types of funds:

Glazing transparent varnishes will retain color and emphasize the texture of wood, protect the surface from moisture, mold and rot;
Opaque topcoat varnishes will help achieve the desired shine and shade, protect against insects, high humidity and ultraviolet radiation;
Oil paints penetrate deeply into the structure of the log, keeping the surface from moisture and dirt. But they take a long time to dry (two weeks) and lose color over time!;
Acrylic paints and water-based varnishes are natural, safe products that provide a dense, elastic coating. They protect against moisture, cracking and fungus. Such compositions allow the tree to “breathe”, but are expensive;
Alkyd varnishes form a hard and smooth surface, retain color for a long time and provide protection from moisture. However, such products do not allow the wood to “breathe,” which over time causes the log to dry out and crack;
Yacht varnish is suitable for places with high humidity and large amounts of precipitation. This is reliable protection against moisture, which is not affected by weather and temperature changes. This varnish does not fade and prevents yellowing of the wood, but when painted it emits an unpleasant odor;
Stain is an affordable and cheap way to finish a log house inside and out. It protects against fungus and pests, does not disturb the wood grain and makes the color more saturated. However, stain requires subsequent varnishing;
Oils and wax are environmentally friendly, safe products that are deeply absorbed into the wood and protect the logs from moisture and dirt. The wax will give the surface a translucent matte shine.

To properly paint a log house, wait until the primer is completely dry. Stir the mixture thoroughly before painting. First, paint is applied in two or three layers. Before applying each new layer, wait until the previous one is completely dry. For painting, use a roller; for hard-to-reach places, corners and ends, use a brush.

When using a spray gun, it is not always possible to achieve an even and smooth coating. In addition, there may be unpainted areas. Apply the final coat of paint in a thin layer from top to bottom.

After the paint has completely dried, apply varnish in two or three layers. For an even coating without layering, allow each layer to dry and apply the product in long, even strokes. For decorative coating, you can use only varnish or only paint. However, the use of both means will consolidate the result and enhance the effect, enhance protection and increase the service life of the wood.

Covering walls inside a house with clapboards and other methods of using natural wood in decoration are quite popular today. Naturally, the question quite naturally arises of how to treat the lining inside a wooden house in order to protect it from moisture and other factors.

In our article we will try to analyze in detail the features of the compositions used, and also provide recommendations for painting and varnishing wooden surfaces.

Review of materials

Why do you need wood protection?

Internal processing of a wooden house is included in the list of mandatory measures for finishing the premises. Indeed, the importance of correct selection and application of a protective composition for wood is difficult to overestimate.

There are several reasons for this:

Firstly, with a long stay in a humid environment, wood fibers swell, and all the parts from which the finishing is made increase in size. As a result, the wall cladding becomes deformed, which can lead to cracks and other defects. To avoid this, the lining and other finishing elements are impregnated or coated with compounds that minimize contact between wood and water.

Secondly, a humid environment together with high temperature creates an ideal environment for the development of microorganisms, including pathogenic bacteria and fungi. The only way to prevent this is to use antiseptic compounds that have bactericidal and fungicidal effects.

Note!
Very often, beginners are interested in whether it is necessary to treat wood with an antiseptic indoors with a normal level of humidity.
In principle, this is not necessary, but in any case, antibacterial or antifungal impregnation will not hurt.

Thirdly, the internal treatment of the walls of a wooden house also performs a design function.. Modern compositions for the most part either contain ready-made pigments or allow the introduction of colors, so that if necessary, we can simultaneously provide moisture protection to change the shade of the finish.

Concluding a brief analysis, it should be noted that the price of high-quality products for protecting wood from moisture and microorganisms is quite high. At the same time, their use significantly extends the service life of the finish, so ultimately, treating wooden walls inside the house is completely justified.

Compositions used

To solve the problems we described in the previous section, a variety of compositions are used today. You can analyze their features using the table below:

Means	Composition and application
Antiseptic primers	Used for preliminary application to wooden surfaces for varnishing or painting. They include bactericidal and fungicidal components that prevent the development of bacterial or fungal colonies. Most are either colorless or give the surface a slight yellowish tint, which is why they are used in combination with other compounds for decorative processing.
Scuba diving	As a rule, they are an acrylic-based varnish. The coating is easy to apply, quick to dry, and environmentally friendly. Since organic solvents are not used in Aqualak, it can also be used indoors - it still does not produce a pungent odor or toxic fumes. When (for example, if you are looking for how to treat the inside of a wooden bathhouse), you should give preference to aqualas with water-repellent additives - then the wood simply will not get wet.
Varnishes for wood	When finishing walls covered with wood panels, more traditional varnishes, such as those used, for example, in the furniture industry, can be used. Varnishing allows you to create a dense inert layer on the surface of the wood, which will prevent the penetration of moisture. Varnishes used for processing wood at home can be transparent or tinted, matte or glossy, etc.
Oils	The main advantage of the oil is that its components penetrate deeply into the wood structure, saturating its fibers with organic compounds and protecting it from moisture. As is the case with scuba tanks, the oils do not contain toxic substances and do not have unpleasant odors.
Waxes	Wood wax is a fairly viscous organic compound that is applied to the finish to give it a characteristic shine and prevent swelling. Very often, wax is used in a mixture with decorative oil - then it also gives a tinting effect.
Paints	As an alternative, you can choose different interior paints. Unlike varnishes and oils, they form an opaque coating, so they can be used to disguise the texture of wood. Most often, non-toxic acrylic and latex water-dispersed paints are used to treat rooms. Alkyd enamels and oil compositions are used much less frequently.
Complex decorative and protective compositions	The best choice for treating wood while maintaining its texture is to use a complex coating. Such compositions are usually used to impregnate wood with simultaneous tinting, as well as to give it additional characteristics, for example, reducing flammability.

As you can see, there is a lot to choose from when it comes to treating wooden walls inside the house. However, it’s not enough to choose – you also need to apply the composition correctly.

Work technology

Preparatory work

If you decide to paint or varnish wooden wall cladding, then the instructions given in this section will help you understand the nuances of the technology.

Work must begin with surface preparation:

If the boards were previously painted or varnished, then the old coating must be removed. We soften the painted layer with warm water or a stream of hot air from a hair dryer, and then remove it with a spatula.
We remove the remaining paint and varnish using a sanding machine.
If we process new wood, then it needs to be sanded all the more. To do this, we successively use several abrasive materials, gradually reducing the grain size - this way we get a perfectly flat surface.

Advice!
If there are defects on the sheathing, then before sanding they must be masked by using a small amount of wood putty.
After waiting for the putty to dry, we clean the area with sandpaper, and then sand the surface.

Afterwards, it makes sense to treat all surfaces with a penetrating water-based antiseptic primer.
Apply the primer in one or two layers, making sure that the wood does not get too wet.
After the primed surface has dried, the lining inside the house can be painted or varnished.

Application of the composition

Both painting and varnishing can be done with your own hands.

The process itself is not complicated, but there are still a few recommendations that are worth listening to:

Having decided how to treat the wood inside the house, it is worth purchasing the selected composition with a small margin. The thing is that the shade of paint or tinted varnish may differ in different batches, so it is better to paint everything with one material.
Before starting work, mix both paint and varnish thoroughly. This is done in order to compensate for the delamination of components that occurred during storage.

To apply the composition, use a wide flat brush. We will also need a narrow brush on a long curved handle - we will use it to penetrate hard-to-reach places.
We apply both paint and varnish in several layers. The more layers and the smaller their thickness, the better the result.
The direction of the strokes should be perpendicular. So, for example, we apply even layers vertically, odd ones horizontally, or vice versa.
After applying each layer, you need to dry the surface. Drying time depends on the type of composition used, so you need to plan the work individually.

And most importantly, during drying, the fresh layer of finishing should be protected from exposure to drafts and temperature changes, otherwise the coating will quickly begin to crack and peel off.

Conclusion

When choosing how to treat the inside of a wooden house, you need to analyze which properties of the material will be your priority. Well, information materials, including a very informative video in this article, will help you understand the intricacies of applying paints, varnishes and impregnations.

Many people prefer to buy or build houses made of wood, as they are attractive in appearance, warm and environmentally friendly. However, such buildings require additional protection from the negative effects of environmental factors. Therefore, it is very important to consult in advance on the features of the external and internal decoration of the house or contact a specialized organization for help. Our company’s specialists perform high-quality processing of wooden houses in the shortest possible time.

Exterior treatment price for a wooden house

Why do you need to treat a wooden house?

The following factors can adversely affect the integrity of the house:

When sunlight hits the surface, the log becomes darker, porous, and easily absorbs moisture, resulting in aging and cracking of the log.
Precipitation and high moisture, due to which products can swell and dry out, causing mold and mildew to form.
The appearance of insects in the walls that damage the integrity of the wood.

Do you want to protect your building as much as possible from these adverse effects? – You definitely need to carry out internal and external treatment of the house.

Stages of impregnation of a wooden house outside

This process occurs in several stages:

application of antiseptics;
use of fire retardant impregnation;
final finishing.

When working outside, specialists use an antiseptic that penetrates deeply into the wood and protects against moisture, mold and microorganisms. After this, fire retardant impregnation is applied. This stage begins a few weeks after using the antiseptic composition. Fire retardant coatings should be applied in several layers. And at the very end you can begin the final finishing.

A house made of wood necessarily requires the application of an antiseptic composition. There are different types of wall coverings: varnish, paint, plaster, brick cladding, siding. Before applying any coating, the walls must be treated with solutions.

The solutions are as follows:

acrylate paints, resistant to external factors;
glazing, emphasizing the natural shade of the tree, and covering, hiding it;
oil paints are well absorbed.

The process of internal processing of a wooden house

When carrying out interior work, water-based products that do not emit toxins and are odorless are most often used. Moreover, they are moisture resistant. In the process of interior finishing, craftsmen first use the composition for the top layer, and then (after it dries) they apply fire-resistant impregnation to the working surfaces. The next step is to apply paint or varnish to the walls of the house. At the same time, you can choose the desired shade, since today manufacturers produce products in a wide color palette.

Wooden houses are one of the most attractive types of housing: they are beautiful and environmentally friendly, and living in them has a beneficial effect on the health and general condition of people. In order for your home to retain all these qualities, proper treatment of the wooden house and its walls is necessary, both inside and outside.

Wood materials have the ability to absorb moisture. Any changes in humidity or temperature levels will lead to their destruction. Externally, this will manifest itself in the form of swelling, drying out of the walls, the appearance of cracks on the outside, or the tree may simply begin to rot.

In addition, there are a number of microorganisms that can spoil wood materials. These are fungi, algae and insects that can cause unwanted darkening of walls, as well as stains on the outside of the house and mold indoors.

It is very important to protect your home from a possible fire.

Types of wood processing

A number of manufacturers process materials in factories, supplying already processed products for residential construction. But there is also the option of treating with an antiseptic at home.

After finishing the processing of wood materials and the subsequent construction of the house, additional external treatment will be required for the walls of the house (both indoors and on the street side), floor coverings and everything that may have contact with water.

All of the listed types of objects have their own special type of impregnation, which will help preserve them in excellent quality during the use of the living space for a very long period.

Wood materials must be subjected to primary antiseptic treatment for the reason that building a house will take quite a long time. Construction materials will be stored outdoors and will encounter many unfavorable factors that will affect their condition. At this stage, it is necessary to treat the walls with a hard-to-wash antiseptic, which can protect the wood inside and outside the room from external factors for 2-8 months and will not affect the color or properties of the wood in any way. Do not forget that wood materials must be stored on special pads to avoid contact with the ground, which will also negatively affect their condition.

Today there are many types of antiseptics, which can be divided into 3 groups:

aquatic;
oil;
chemical.

Before treating with an antiseptic, you will need to calculate the area of the surface to be treated. The manuals for all antiseptics include information about the consumption of antiseptic per 1 meter. This will allow you to accurately calculate the amount of antiseptic that may be required.

Basic processing rules

Before starting treatment with an antiseptic, it is necessary to clean the wood materials from the outside, for example, using a metal scraper. Hard-to-reach areas or areas of wood that are damaged are processed first, and only then smooth and easily accessible areas.

At ambient temperatures below +5 °C, the walls of the house cannot be treated with special solvents. And treatment with antiseptics, which tend to dissolve in water, is prohibited at temperatures below +10 °C. Treatment by any other means cannot be used if the air humidity is above 80%.
