Log houses and bathhouses are very popular, which is quite natural, because wooden house is considered more environmentally friendly than brick or stone. A log house is usually made from rounded timber. In winter, the walls of such a house are warm, and in summer they keep the desired coolness. For a log house to last a long time, it needs processing, polishing and high-quality impregnation. But how to treat a log house, how and when to do it? Is it possible to do without this?

Why process logs?

Wood is a living material; it is susceptible to fungal infections and mold; in addition, wood can delaminate, dry out, or, conversely, swell. To avoid troubles associated with the properties of wood, it is necessary to carry out processing.

Inside the walls of the house are not exposed aggressive influence environment, which cannot be said about baths made of wood. In addition to the indicated impact of the external environment on the walls wooden log house, inside the bathhouse the walls are affected by elevated temperatures and humidity. Because of this, the need for additional protection of the walls of the bathhouse from the inside is so important.

Not the last place appearance Houses. Therefore, the treatment is not only functional, but also aesthetic in nature, since almost all impregnation agents for log houses have decorative properties.

The processing of the log house occurs in several stages using various compounds, including:

• antiseptic;
• fire retardant;
• whitening.

Pre-grinding

Before treating a log house with impregnation, it requires grinding, which solves a number of issues:

• eliminates roughness;
• masks cracks;
• removes bark;
• makes it look better.

In addition, sanding prepares the logs for impregnation with other substances after this work. Grinding is carried out when the upper surface of the timber dries well. If you try to sand wet wood, it will cause the wood fibers to separate.

Grinding is carried out in several ways:

1. First, a grinder and an abrasive disc are used.
2. Then use a sander and attachments with to varying degrees graininess.
3. Afterwards, final sanding is carried out with a fine-grained nozzle.

The sawdust remaining after grinding is removed or used for gardening work. After grinding the rounded timber, you can directly impregnate the log house.

Bleaching agents

To protect the surface of the rounded timber from damage by a fungus that causes blueing of the wood, the log house is additionally treated with bleaching agents:

• "Sagus";
• "Sagoy";
• "Neomid 500";
• “League” is a new drug, notable for the fact that it is able to revive an old tree, rid the log house of blackness and blueness, restoring its former appearance.

First, the log house is treated with a bleaching agent, and then with an antiseptic.

Antiseptic treatment

Antiseptic impregnation is used to increase service life wooden structures and is carried out both inside and outside the house and bathhouse. Antiseptics prevent the development and proliferation of bacteria inside the walls. The initial impregnation with an antiseptic is carried out by the manufacturer of the rounded timber, after which the wood is aged for at least another six months to a year for complete drying and only then is it delivered to the site.

Easy-to-clean and difficult-to-clean antiseptic formulations are used to treat internal and external surfaces. Easily washable ones dry quickly and are less resistant to moisture; they are applied to internal surfaces. Hard-to-wash types dry extremely slowly, but are quite resistant to washing out by precipitation, and are recommended for external processing of rounded timber.

Antiseptic preparations used for external surfaces of timber:

• “Neomid 440” (protects timber from bacteria, fungal diseases and viruses for up to 15 years);
• "Aquatex" (in addition to the main protective functions, it gives the timber the appearance of valuable wood, and also protects the walls of the bathhouse from rotting, water, sun rays);
• "Prosept Ultra";
• "League-Bioshield".

Antiseptics for impregnating the inside of a log house:

• "Neomid 430";
• "Prosept Interior".

The antiseptic is made using synthetic and natural oils, which are able to penetrate into the wood fibers, after which they form a stable compound. Coating with antiseptic drugs is carried out in several stages. Each subsequent layer can be applied only after the previous one has completely dried. Processing is not allowed until the rounded timber has dried out, or in wet weather.

Fire retardant treatment

Since wood is highly flammable, first of all, you need to think about fire protection. Fire retardants must be used for processing log wood in any case.

For fire-prevention impregnation the following means are used:

1. “Neomid 530” - in addition to fire-fighting properties, it has protection against biological damage, as well as decorative properties.
2. "Senezh Ognebio" - provides protection against rotting, fire, and insect pests.
3. "Phenilax" - protects against fire and internal damage, penetrating deep into the wood.
4. “KSD” is a product that, in addition to fire-retardant properties, is an antiseptic.
5. "Pirilax SS-20" - used to treat the walls of the bathhouse inside.
6. "Pirilax 3000" - this product is used to treat the outside of baths.

Fire protection occurs when a rounded beam is exposed to an open flame or high temperatures. After a fire, a foam layer appears on the treated walls of the log house, which stops the access of oxygen to the surface and prevents the fire from spreading.

Stages and methods of applying compositions

So, the processing and impregnation of the log house is carried out in several layers. The logs must first be covered:

• bleaching agent to avoid premature aging of wood;
• antiseptic - the first layer is applied by the manufacturer;
• fireproof layer.

Separately, it is worth highlighting the means with which to treat the ends of the logs. The fact is that the end part of the log absorbs moisture more strongly than the side. To prevent the wood from absorbing moisture, it is necessary to cover the logs with a water-repellent layer.

The ends of the logs must be coated at least 5 times, Special attention, focusing on the logs of the lower tier, while the side part will be sufficiently covered with 2 layers. It is advisable to carry out additional treatment of the lower tier by all means, since the log house below is subject not only to climatic influences, but also to the influence of dampness from the ground.

Layering methods:

1. You can cover the surface with a roller or brush; this method is suitable for thick mixtures.
2. Using a spray (spray) - for aqueous solutions.
3. The surface can be coated using the immersion method, so the timber is coated evenly on all sides.

It is not worth saving on the processing of a wooden frame, so that you do not have to incur additional costs to eliminate all sorts of problems.

A wooden house provides people with the opportunity to enjoy the comfort and coziness of environmentally friendly housing. But at the same time, a tree is a living organism, and wooden buildings need more care than brick and concrete structures. Natural natural phenomena, such as rain, wind, sun, do not have the best effect on wood, which under their influence ages and collapses. Insects and microorganisms, which are very fond of woody structure, where they feel nourished and warm, make their contribution. Treatment will help prevent destructive processes wooden house outside with special antiseptic agents that protect the tree from the negative effects of natural and biological factors.

Living in a house made of untreated lumber poses a danger to humans, since fungi and mold appear on the wood, which are harmful to health, bugs settle in and eat the wood, and rotting processes begin to develop.

If these processes are allowed to develop uncontrollably, then after a short period of time the wooden house will become uninhabitable. Timely treatment will prevent all these unpleasant phenomena.

Any wooden house, both new and old, needs treatment. For a new building there are three stages of processing:

1. Antiseptic treatment of logs and beams at the production stage or self-treatment at the construction site before the construction of the structure.
2. Treatment immediately after construction.
3. Coating the house with an antiseptic after going through the shrinkage process, 6-12 months after construction.

An old log house must be treated every 3-5 years, depending on the finishing method and the quality of the material.

What to process log house outside? The answer to this question depends on what problems need to be solved using processing. There are several groups of products designed to protect the external walls of a wooden house from various negative factors:

1. Antiseptics. Designed to protect wood from mold, fungi, microorganisms and insects. These drugs prevent wood rotting and also effectively combat existing foci of biological damage.

Antiseptics are presented in two types:

• Impregnating, hard-to-rinse compounds. Impregnations are deeply absorbed into the wood structure and are not washed out for years, protecting the wood from biological influences.
• Coating preparations. After treatment with these products, a protective film is formed on the surface, which does not allow moisture to penetrate into the wood. Film-forming compositions are especially relevant for bath treatment, because they are resistant to high temperatures.

1. Whitening products. Designed for lightening wood. The preparations whiten areas covered with a blue coating and at the same time destroy fungi that cause darkening of the wood.
2. Fire retardants. Gives wood resistance to open fire. A wooden surface treated with this product does not ignite instantly, as unimpregnated wood usually ignites, and can withstand open flames for several hours.
3. Preservative impregnations. Ensures the safety of wood. Impregnating compounds are responsible for the smoothness of the surface and prevent cracking and the formation of unevenness.
4. Primers. Primers have protective properties, protecting the wood from external influences. In addition, they provide good adhesion of paints and varnishes to a wooden surface. It is recommended that before painting the exterior walls of the house, coat the wood with a primer.
5. Protective and finishing compounds (varnishes and paints for wood). They are primarily intended for decorative finishing log walls, but at the same time have protective properties.

Means for external processing used for protection external walls wooden houses, which are constantly exposed to harsh street conditions: ultraviolet radiation, precipitation, temperature changes.

In this regard, the main requirements for antiseptics for external use are resistance to any manifestations of bad weather and provision of reliable protection of wood from adverse natural factors.

It should be noted that many types of antiseptics intended for external works, have a persistent bad smell and contain harmful components. For external compositions such indicators are acceptable, but when working with them you should be careful and use protective equipment.

There are products for a wooden house that combine different properties: protect wood from rotting, mold, insects, fire and at the same time form a decorative coating on the surface. The value of such compositions is low, since they are ineffective. Best result can be achieved using several highly specialized means.

If impregnation is required for raw wood, the moisture content of which is more than 20%, it is necessary to use alcohol-based preparations. Alcohol molecules promote deeper penetration of the antiseptic into the wood structure.

Concentrated products are much more expensive than drugs diluted in the factory. However, the consumption of the concentrate is an order of magnitude less than the ready-to-use composition. When using a concentrated drug, it must be diluted strictly according to the manufacturer's instructions.

To decide what is the best way to treat wood, you need to take into account the following factors:

• range of tasks to be solved;
• product consumption per 1m2;
• number of processing layers;
• method of applying the composition;
• resistance of the drug to natural factors;
• guaranteed service life.
• what effect does the drug have (preventive or therapeutic).

1. Primary. Carried out by lumber manufacturers or performed during construction. It is especially important to properly treat the elements of the log house in contact with the soil, because they are exposed to moisture more than other parts. These are the lower rims of logs, piles, subfloors, foundations, external and interior walls basement
2. Preventive. Healthy wood is subjected to this treatment in order to prevent the formation of mold, mildew, insects and prevent rotting processes.
3. Therapeutic. The treatment is carried out on a tree that has foci of biological damage. Medicines stop rotting, kill fungus and mold that have penetrated deeply into the layers of wood.

Please note that preventatives should not be applied to diseased wood. Preventive antiseptics cover the wood with a film under which microorganisms will continue to quietly multiply. Therapeutic agents can be applied for preventive purposes if the home is expected to be used in unfavorable conditions.

Stages of external processing of a wooden house

The processing process consists of the following stages:

1. Application of antiseptic. An antiseptic is used deep penetration, which is applied in one of three ways: with a roller, a wide brush or a spray gun.
2. Treatment with a fire retardant is carried out two weeks after applying the antiseptic. Usually for effective protection 3-4 layers of coating are required.
3. The final finishing is carried out no later than two months after antiseptic treatment, since the protective agent can be washed off by precipitation. Finishing options: external walls can be varnished or painted, or decorative plaster or cover the surface with siding or clapboard.

The ends are the most vulnerable places of the log house; intensive absorption and evaporation of moisture occurs through them, which leads to deformation and the appearance of cracks. Therefore processing protective equipment takes on special significance when we're talking about about the ends of a wooden house.

Protective compounds create a breathable film at the ends that repels moisture and regulates evaporation. Depending on the condition of the ends, the preparations are applied in three to five layers. Single processing is undesirable. It is recommended to use oil- or water-based products, for example, the water-soluble antiseptic Belinka has proven itself well.

If there are deep cracks at the ends affected by fungus and rot, it is necessary to use a deep penetration compound. It is advisable to treat with preparations that change the tone of the wood, this makes it easier to control the degree of application.

Primary treatment is carried out during construction, re-application of antiseptic is required every 5-7 years, during which time the previous coating is usually washed off.

Features of wood treatment with antiseptic

The antiseptic is applied only after cleaning, sanding and degreasing the surface to be treated.

It is best to start treating external walls from the shady side of the house. First, damaged and problem areas are treated.

If the log house was erected in the summer, the antiseptic must be applied no later than two weeks after construction.

Winter log house natural humidity It is not worth processing immediately, since the composition will freeze at sub-zero temperatures, and in the spring it will thaw and be washed off. It is advisable to start work at a temperature of at least 10 degrees.

Processing of a house made of laminated veneer lumber can begin immediately after construction, regardless of the time of year.

Difficulties in self-processing

Many owners wooden houses it seems that antiseptic treatment of the external walls of a log house is easy and simple work. Indeed, if you look at it, there is no difficulty in treating with an antiseptic, but only if the work is undertaken by knowledgeable and trained specialists who have repeatedly carried out the treatment and know all its intricacies.

If non-professionals try to do the treatment, then, as a rule, they find it difficult to choose a drug and do not know how to apply the product correctly. But right choice antiseptics and compliance with the technology of its application are the most important conditions high-quality and durable processing.

Home craftsmen also make other unforgivable mistakes:

• due attention is not paid to surface preparation;
• one layer of antiseptic is applied, which guarantees short-term protection of the wood;
• processing is carried out at low temperatures.

All this affects the quality of processing and requires repeated work.

A wooden house is environmentally friendly and safe housing, and will always be popular. Natural wood compared to others building materials, does not emit toxic hazardous substances, promotes rapid exchange of oxygen in the room and simply has a pleasant forest aroma. Always in a wooden house Fresh air, it is warm in winter, and hot summer days- cool, comfortable environment and cozy atmosphere will delight you for many years.

The ease of assembly of factory-made elements from logs or profiled timber significantly reduces installation time. Due to the relatively light weight of the walls of a wooden house, a deep, expensive foundation is not required. And also, thanks to the beauty and unique patterns of wood given to us by nature, the aesthetics of the materials does not require serious and expensive finishing.

PROCESSING A WOODEN HOUSE OUTSIDE: SELECTION OF PRODUCTS AND STEP-BY-STEP INSTRUCTIONS

However, despite everything positive features, wooden houses also have a minus. Wood, as a natural material, is subject to negative environmental influences. Sun rays (ultraviolet), moisture in the form of precipitation, insects lead to the fact that the material can gradually darken and collapse. Mold, cracks and fungus may also appear, and the structure may subsequently lose original appearance. But in modern world these problems can be avoided due to the necessary processing of the log house inside and outside using various means.

WHY DO YOU NEED TREATMENT OF YOUR WOODEN HOUSE OUTSIDE?

• Protects wood from destruction;
• Retains the original appearance of a bathhouse or house made of logs or profiled timber 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 required for log house, since fire is a significant threat to wood.

HOW TO CHOOSE PROCESSING PRODUCTS

Today, the market offers a lot of different products for treating wooden houses, both outside and inside. It is very important that the products you choose for processing are environmentally friendly and preserve the natural properties of wood. Also, 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:

1. Antiseptics are deeply absorbed into wood, increasing the resistance of wood to moisture and microbes. Antiseptic agents include wax, protective varnish and oils. They destroy mold and blue stains.
2. Fire retardants prevent the spread of fire. At elevated temperatures, the composition of this product comes out and forms protective film on the surface of the wood. This product prevents instant ignition and resists open fire for several hours.
3. Preservative solutions and impregnations keep wood in good condition. Special impregnating materials maintain the smoothness and evenness of the wood surface and prevent cracks. And film-forming compounds additionally create a water-repellent barrier, which prevents the wood from absorbing excess moisture and, accordingly, prevents the creation of a damp negative environment in the wood. A primer or wood oil is suitable for these purposes.
4. Protective and finishing agents are largely intended for decorating wood, in other words, for creating and long-term preservation of the aesthetic appearance of a house or bathhouse. These are paints and varnishes for wood. They protect wooden surface from fading and dirt. There are also special bleaching compounds that will prevent the wood from darkening over time.

You should not choose one product that will immediately protect against mold and rot, insects and fire, while also performing decorative functions. Practice shows that such impregnations are not very effective and will not give the desired result. To achieve high-quality and durable results, it is better to use fire retardants, antiseptics and decorative paints and varnishes separately, since each of them will give a more significant effect in the area of ​​​​its intended purpose.

HOW TO CORRECTLY TREAT THE OUTSIDE OF A WOODEN HOUSE

• Immediately after assembling a wooden house or bathhouse, it is necessary to treat it with antiseptics inside and out for the first time. We recommend paying special attention to the processing of ends and elements in contact with the foundation. Antiseptics must be applied in at least two layers;
• Primary processing cannot be carried out at temperatures below 10-12 degrees!;
• The next treatment is done after the log or timber has completely dried and the frame has completely shrunk. This takes 12 - 18 months if the wooden house was made from materials with natural moisture. This finishing involves the final complex and multi-layer processing of the house, which will ensure long-term protection of the log. It is also important to apply antiseptics to a dry and clean wood surface!;
• Before processing, additional grinding of the log or beam is necessary to remove the top layer, in which fungus and microbes may have accumulated during shrinkage. It will remove defects in the log and level the surface. Grinding wooden walls definitely necessary for an old house, since it is important to completely remove the previous covering;

• 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, apply two or three layers antiseptics. 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 paint and varnish materials achieve a certain color or shade, matte or glossy shine. If you want to preserve the natural color of the wood, use transparent paints and varnishes.

WHAT AND HOW TO PAINT THE FRAME FROM THE OUTSIDE

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 persistent 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 varnishes on water based- 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 flat 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 big amount precipitation. This reliable protection from 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;
• Wood stain - affordable and cheap way finishing log house inside and outside. 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. Use a roller for painting, and a brush for hard-to-reach places, corners and ends.

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 covering 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.

Building your own wooden house is a pleasant and important event. A wooden house is environmentally friendly and unity with nature, the best choice for those who care about their health and the health of their loved ones. However, this is a very big responsibility. After all, wooden structures require much more care and attention than, say, stone buildings. Anyone who has built their house from wood, or those who are just planning to do so, are thinking about how to treat a wooden house outside and inside in order to protect it from negative external influences and make its operation long and comfortable.

Why is it important to protect wood?

Natural wood has its own specifics, like other materials, so they must be taken into account when using them. In addition to a number of advantages, natural wood has a number of disadvantages, for example:

• Flammability;
• Possibility of rotting;
• Exposure negative impact some insects;
• Drying out over time;
• Cracking;
• Dependence on ambient temperature.

These factors necessitated the need to protect the wood from which a wooden house is made. Firstly, the wood is natural natural material, which easily absorbs moisture. Any slight fluctuations in air humidity can lead to swelling, cracking and rotting.

Secondly, another enemy natural wood various microorganisms become. It could be mold a large number of varieties of mushrooms, insects and algae. Fungal spores, which are especially abundant in humid air, enter the tree and germinate in just a few hours. The main signs of such an infection are blue spots, darkening, plaque and increased humidity. There are also types of mushrooms (for example, white brownie) that can “eat” a thick 40mm. oak board within one month!

Another danger that owners of wooden structures are exposed to is fire. Therefore, it is necessary to ensure maximum fire safety in such a house and minimize any risks of fire.

How to properly protect wood

To protect wood from damage by microorganisms, various methods are used.

Wood protection methods:

• Methods of a structural nature - isolating wood from the ground, stone and concrete, installing special ventilation channels, protecting the building from rain, fog and moisture;
• Chemical methods that involve treating wood with special protective agents. These include antiseptics and fire retardants, which protect wood from germs and fires, respectively. This is the most common method, and also the most inexpensive and effective.

Protection of a wooden house is achieved through the use of special water-soluble agents, compositions based on volatile chemical compounds, oil antiseptics, special pastes and other means. On modern market the most wide application received antiseptic and fire-bioprotective solutions made on a water basis.

It is worth noting that water-based antiseptics for a wooden house are environmentally friendly and non-toxic materials, which is very important, especially when internal processing. The treatment of a wooden house to protect it must take place in several stages - from its construction to finishing. At the same time, protecting it from the inside and outside has certain differences.

How to treat the outside of a wooden house - the main stages of processing

External processing of the log house takes place in several stages:

1. 10-14 days after placing the structure under the roof. If the house was built in warm time years, then after 2 weeks it is necessary to carry out treatment with special compounds - first with antiseptics, and then with fire retardants, or with complex fire-bioprotective agents. It must be processed in 2 stages, applying antiseptic in two layers. If the log house was erected in winter time, then you should wait until the temperature rises to +10-12 ºC, after which they begin impregnation using a spray gun. However, this will only protect the house for 3-5 months;
2. 3-5 months after the initial treatment with an antiseptic and fire retardant, it is necessary to use a finishing color coating that will give additional protection from rot, insects, and will also preserve the primary layer.

Internal processing of a wooden house

The interior of such a house is treated with water-based solutions and must be carried out at the same time as the first external treatment. After this, after 14 days, the finishing stage of coating is carried out.

What we need for this:

• Thin brush;
• Natural bristles;
• Final protective varnish, for example, Capacryl Impragnier - Lazur from the German company Lacufa.

Recommendation. If blue or gray spots or darkening begin to appear, they should be treated with special chloride-based wood protection products, for example, Pinotex Wood Oil. The product is applied to the affected areas in a thin layer, and within a few minutes the wood will return to its original appearance.

Wood house processing technology

The described stages were considered in general terms, and much more complex. If you want to treat a wooden house in winter , then you should choose materials with a wider temperature range of operation, but in general the technology will differ little:

1. The first treatment is with special compounds that provide deep antiseptic protection and penetrate deep into the wood structure. It is produced to protect wood from mold, mildew and rot. Here you can use Pojuste from Tikurilla or Teknol Aqua 1410 from Teknos;
2. Next, it is necessary to treat the ends to protect them from moisture. By applying a special moisture-protective agent, you stabilize the moisture balance of the tree, thereby slowing down the drying process of the tree. It releases moisture gradually and evenly, without sudden changes in humidity and, accordingly, cracking. Here would be better suited material Teknol JRM;
3. Deep penetration primer, which fills microcracks in wood and ensures a reliable level of adhesion of subsequent layers of materials;
4. Finishing – several layers of surface materials (paint and varnish or others) are applied. They form finishing coat and provide maximum safety and preservation of operational properties, as well as imparting a finishing color.

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 - natural material which is exposed 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. Great importance They also have decorative properties. There are four main groups of products that will be needed to treat the outside of the house:

1. 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.
2. 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.
3. 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.
4. 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. Use a roller for painting, and a brush for hard-to-reach places, corners and ends.

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.
