Reliable protection of your new wooden house from external negative factors. Overview of materials and methods for external processing of a log house How to process the external walls of a wooden house

The construction of wooden country houses is popular in many countries of the world. Every owner wants his house to retain its beauty and quality for many years to come. The processing of the walls of a wooden house is necessary so that a few years after the construction, the wooden house does not look like a barn.

Features of wooden buildings

When building a house, cottage or building from a wooden beam, you need to learn about some of the features of such buildings:

• a wooden house is an environmentally friendly dwelling. Such a house has a positive effect on human health, naturally maintaining good humidity, creating a favorable microclimate inside the premises;
• wood does not like sudden changes in humidity and temperature. This can lead to swelling, shrinkage, cracking of the timber and its further destruction;
• wood is an excellent breeding ground for harmful microorganisms that destroy it. The most dangerous is the porcini mushroom, it is able to destroy the beam in a short time;
• wood is sensitive to fire, so it is necessary to treat it with special fire-fighting compounds.

Reasons for the destruction of a wooden beam

The main negative impact on this natural material is exerted by the following factors:

To secure the destruction of your dacha due to one of these factors, it is required to carry out the processing of walls inside and outside the house.

Beam protection

When a house is built, wood must be stored properly so that it does not receive critical damage before it is used for its intended purpose. For storage, a canopy of the required size is built. Flammable substances should not be stored near it, and the beam should not lie on the ground. Throughout the construction, the building material must not be allowed to be damaged or completely destroyed.

From already affected areas, mold can be removed by grinding

The second stage of tree protection will be its treatment with an antiseptic. Now in the construction market there are many interesting offers that protect the material from 2 to 8 months. In the composition of such substances there are no components that can harm natural building materials.

There is a high probability that black spots may appear on the surface of the timber, which cannot be left. To eliminate them, modern bleaches are used, which contain chlorine or active oxygen. It is not recommended to buy cheap substances, it is better to take a more expensive one, from a trusted manufacturer, which is created in accordance with all quality standards.

It doesn’t matter what material the house is built from – over time, any structure is subject to wear and tear. Then repair is needed to prevent destruction. Inspection of buildings allows you to understand the degree of deterioration and whether the building needs reconstruction. Specialized organizations conduct an examination and issue final documents

Antiseptics

A simple and reliable way to extend the life of a tree is antiseptic chemicals, depending on the manufacturer and composition, they can be transparent or tinted.

Senezh

Substances from this manufacturer are used for:

• full protection of the beam throughout the entire period of its operation;
• protection from harmful substances and influences, as well as from fire;
• final finishing of wooden walls;
• removal of gray and black spots.

Neomid

To treat hard-to-reach places with an antiseptic, you can use a paint brush

Neomid products are represented by antiseptics (washable and non-washable) and transparent oil paints.

Belinka

Products are used to protect all tree species: from budget to elite. Protects from any harmful effects, preserves the natural color and texture of the building material.

Aquatex

Production takes place according to all modern standards, there are no harmful chemicals in the composition. The product is a paint and varnish product of different colors (including colorless), which contains antiseptic components. Easy to use, quickly sets to the wood without pretreatment with a primer.

Rogneda

An environmentally friendly product that will not harm the health of people and animals. Provides material protection up to 50 years.

It is better to grab the antiseptic with the surface if the walls are sanded before processing

They can process both fresh building materials and those that are already affected by harmful microorganisms to stop their spread and complete destruction.

Aqualor

Budget option in the Russian market. The antiseptics of this brand are based on water. Provides an acceptable level of protection. It is possible to apply material on wood only at positive temperature.

Tikkurila

A Finnish giant company that supplies paint and varnish products of various categories to the market. Tikkurila antiseptics protect timber from all kinds of harmful effects, extending its service life up to 70 years.

Processing the ends of the timber

The ends are exposed to moisture many times more than the rest of the surface of the material. Without proper end protection, soon after construction is completed, the strength of the entire structure will be minimal. Protective impregnations form a protective layer on the ends, which reduces the penetration of moisture and normalizes the rate of evaporation.

To process the walls of the bath from the outside, you can use simple antiseptics, but for internal processing you will need specific tools.

The processing of this part of the timber is very important, it will reduce the cracking of the building material. Such processing is carried out both outside and inside the house. You can apply the impregnation with any painting tool: brush, roller or spray.

If the budget is limited, you can buy an oil-wax antiseptic, as it is better absorbed, which leads to lower consumption. Damaged ends are recommended to be protected with a deep penetrating agent.

Fire Protection

Wood is flammable, so it must be protected from the effects of fire. Most modern antiseptics include in their compositions components that protect the tree from fire. If there are no such substances in antiseptics, you need to use antiperine.

Experts recommend providing the first group of protection against ignition, since the second may prove to be ineffective. To do this, apply 1-3 layers of the substance more than indicated in the instructions from the manufacturer. When choosing a solution, be vigilant: some compounds with any number of applied layers will provide only the second group of protection.

For the processing of load-bearing structures, it is necessary to use compositions that change the color of the building material. This allows you to clearly see the degree of security of the desired structures. Before the applied layers are completely dry, it is imperative to protect the surface from drafts and moisture.

Protection against fungus and mold

Specialists apply protective substances in one of three ways:

• smooth immersion of the material in the antiseptic;
• processing with a paint brush;
• spray treatment.

Lining walls can be painted after applying an antiseptic to extend its service life

Protection against fungus and mold allows you to extend the life of the tree up to 45 years. When buying an antiseptic, it is recommended to pay attention to complex compounds that protect natural material from all sorts of harmful effects.

Woodworm protection

Elimination of black spots

• with chlorine. Aggressive chemicals that remove not only stains from fungus and mold, but also resinous and tannins that contribute to the deformation of the wood structure. Such bleach can only be applied using gloves and a respirator;
• with active oxygen. Mild chemical. Weakly affects the structure of the beam, does not penetrate deep into. During the application of this bleach, gases that can harm human health are not released.

For better adhesion of the antiseptic to the surface, it is recommended to pre-grind the walls

Processing the walls of a wooden house is an important process. Such protective measures will protect the natural building material and extend its service life by several decades. We recommend doing the procedures even before building a house or cottage.

If time was lost in the early stages of construction, and wood damage has already begun, do not despair. It is required to quickly carry out all the necessary work to get rid of the harmful effects on the wood structure and protect it from repeated damage in the future.

Modern wooden buildings simply delight with their splendor and originality. Today, architects are able to fulfill any individual order. They will build not a simple fairy-tale tower, but a luxurious modern palace. Wooden houses are built one or multi-storey, with a veranda, terrace or attic. The beauty of appearance always attracts the eyes of passers-by.

The technology of thermal insulation of the foundation of a wooden house using extruded polystyrene foam.

However, the house should look beautiful not only from the outside, it should have a beautiful and unique interior. When the construction of a wooden house is completed, its walls must be subjected to appropriate processing. The question arises, how to process a wooden house inside? Let's try to answer it.

How to process timber: some features

Before you start, you need to wait for the complete shrinkage of the wooden walls. The most active period of shrinkage is the first 2 years after the completion of construction. During this time, the wood receives maximum compaction, it finally caking.

Of course, the shrinkage process will continue for another 5 years, but it is less active. The beam at this time receives a deformation of its dimensions, the length changes, the width goes away. Given this, it is necessary to leave an expansion gap when installing blocks for doors and windows.

The scheme of finishing the walls of a wooden house from the inside with drywall.

After the period of active shrinkage of the building has passed, approximately 2 years, you can begin processing the internal surfaces of a wooden house. At this time, you can start painting the walls, sheathing with drywall, laying ceramic tiles.

To maintain warmth and comfort in a house built of timber, you need to improve it. To this end, the following is carried out:

1. The foundation, installed ceilings, roof and walls of the house are isolated.
2. The facade of the building is being insulated, the outer walls are sheathed with siding. Without this, the thermal insulation will very quickly become unusable, the inner surfaces of the walls will become covered with condensate.
3. When walls are installed, interventional floors must be well insulated. If this insulation is not enough, you can make additional insulation under the drywall.

A wooden house always requires interior work. Moreover, this is due not only to the laying of the insulation of the cracks formed, it is also the processing of the walls. In order for the built house to have a long life, remain reliable and easy to operate, at the very first stages of construction, internal processing of all the walls of a wooden house is done.

To neutralize the emerging mold foci, a variety of antiseptics, special disinfectants, which include sodium hypochlorite, are used.

Today you can buy a variety of protective antifungal solutions, but the choice of such antiseptics always remains with the owner of the house. Of course, wooden walls, various ceilings and partitions treated with the latest compositions will receive powerful protection against decay, the building will stand for more than a dozen years. When surfaces are processed inside a house (of course, a wooden one), one must not forget about the safety of the people who will live in it.

What paint is better to choose?

After the construction of the house and its final shrinkage, the issue of interior decoration of a wooden room becomes the most relevant. For long-term preservation of the aesthetics of natural wood, it is necessary to use the latest paints and varnishes.

Today, a huge amount of paints and varnishes is produced.

The use of various transparent colors will emphasize the texture, preserve the naturalness of the surface inside the house. On top of that, transparent paints have the property of protecting wood from premature aging.

Hardware and specialty stores sell numerous types of paints and varnishes. Managers can get detailed advice on what paints should be used to paint the inside of the house so that the wood does not lose its natural qualities. Wall painting not only decorates the house, but also protects the wooden house from small rodents and various pests.

When choosing paint, you need to remember that most paints and varnishes can be harmful to health. Therefore, you need to very carefully and carefully choose such a paint. The health of residents, long-term operation of the building directly depend on the paintwork of the house from the inside.

How should the interior design inside the house look like?

The layout of the premises should correspond to the tastes of the owner. Someone believes that a wooden house was created only for comfort and coziness, so that it has all communications, so that various utility rooms are built.

Someone considers a country house the best expression of their solidity. However, the environmental friendliness of the house and the individual microclimate of the premises will always remain a priority aspect. Any owner always strives for a fashionable and functional design of the interior of a wooden house.

When a building is being designed, it is necessary to establish exactly where the windows will be located, what size they will be and their number. Installation of modern double-glazed windows will create a modern look to the building, it will help to minimize the resulting heat loss. The layout of the interior of the house is highly dependent on the number of residents, on their preferences.

Many owners of wooden houses make workrooms, equip gyms and libraries. To save usable space, they use the attic, where they make a children's room, a bedroom, arrange a workshop.

To preserve the unique atmosphere of the built attic, good natural light is required. In this regard, special attention should be paid to windows when designing a room. The highlight of the house can be the slope of the walls of the attic, it will give the room originality and originality.

You can decorate the interior of a wooden house in different ways, perhaps it will be classicism or avant-garde. This issue can be resolved by consulting with an experienced designer. You can, of course, realize your own extraordinary idea.

A little about security

An important role is played by the interior of a wooden house. It should have all household amenities. However, at the same time, the simplest safety rules must be observed in the house.

1. The walls of a log house are impregnated with a special fire-fighting compound.
2. Conducted electrical cable, it is necessary to make double insulation. It is advisable to lay it using a special metal hose. You need to make an emergency shutdown.
3. The interior space can be made in any style, while it is very important that the building has coziness and comfort. The premises must guarantee safety and be functional.

Exterior processing of a wooden house is an important part of its construction. The properties of natural wood are such that the material has to be impregnated and coated with special protective compounds. This helps to extend the life of the building, increases the resistance of its external surfaces to the harmful effects of the environment.

Fig.1. To give a wooden house durability, it is necessary to protect the walls from external influences.

Typical loads on wood

Factors that can damage wooden structures include:

• Ultraviolet irradiation.
  UV rays destroy wood lignin, the substance that holds cellulose fibers together. Therefore, the surface loses its smoothness and is easily contaminated. In addition, even with a short exposure to sunlight without protective treatment, the log house darkens. With longer insolation, the tree acquires an unattractive gray tint, as a result of which the house seems dilapidated.
• Moisture exposure.
  Without waterproofing, wood quickly absorbs water and swells. In dry weather, it gives it away, decreasing in volume. Such vibrations cause stresses in the structure of the material. As a result, cracks appear in it, including adhesive ones (at the joints of logs). Moisture is absorbed most intensively through the ends.
• Mold, fungus.
  High humidity contributes to the development of mold fungi, blue, rot. The first two types spoil only the appearance of wood surfaces. Putrefactive fungi destroy the structure of the tree. Gray mold is also dangerous for health, as it can cause severe allergic diseases.
• Insect pests.
  The activity of carpenter beetles greatly reduces the quality of the wooden structure. The main damage to timber is caused by the larvae of these insects, which gnaw on the surface layers of wood, making long passages inside.

Special impregnations and paints help prevent these problems and preserve the quality of wood for a long time.

Fig.2. Wooden houses, not treated with special means, are subject to corrosion processes, as well as the formation of fungus and beetle larvae.

Means for the protection of wood structures

Prevention of damage to the structure and surface of the tree is carried out immediately after the construction of the house. For this purpose, compositions of a specialized or complex action are used.

Such funds are divided into three large groups:

• Antiseptic impregnations and primers. Protect the house from the destructive action of moisture, mold, insects.
• Flame retardants. Flame retardants that increase the resistance of wood structures to the action of open fire.
• Combined funds. They provide comprehensive fire and biological protection of a wooden house.

As a rule, products based on organic solvents are used to treat walls from the outside. They are more difficult to wash out than water-soluble impregnations, therefore they act more effectively.

Wood is treated with antiseptics immediately after felling in order to preserve the material during transportation and storage. Such protection is valid for a short time, therefore, after construction, the wooden structures of the cottage are again covered with protective impregnations.

Fig.3. To reliably protect the house from fire and other destroyers, fire retardants and various wood impregnations are used.

A set of measures for the protective treatment of the house

To increase the life of the building, all its wooden parts are treated accordingly.

Antiseptic treatment of critical structures

The elements that are constantly in contact with atmospheric and soil moisture include pillars, piles, lower crowns, logs, subfloor plane, facades, gables. They are carefully coated with antiseptics with a fungicidal effect, which are intended for primary processing. Penetrating into the structure of the tree, these compounds prevent the development of fungal spores, bacteria, insect pests.

Protecting wood from fire

Wood can be treated with flame retardants at the stage of lumber production. To do this, the latter are immersed in a solution of a means that provides fire protection. Fire prevention can also be carried out after the construction of a cottage, dacha, bath. In this case, fire retardants are sprayed onto surfaces or applied with a roller or brush. Wooden surfaces are also treated with flame retardants inside. In this case, the fire protection period is increased.

Combined fire protection

Most protective impregnations have a complex effect. They not only prevent the ignition of wooden elements, but also provide an antiseptic effect. When processing rafters and wooden floors, 1 degree of fire protection is achieved. This means that the structures will resist combustion for the duration of the fire. For this purpose, the surfaces are coated with a flame retardant several times or a powerful impregnation is applied once.

End protection

The most intense evaporation and absorption of moisture occurs through the ends of the logs. As a result, these parts of the log house quickly rot and crack. Preventive measures that are taken at the production stage, as well as during the construction of a log house, help to avoid such a problem. To do this, the ends are covered with moisture-proof agents, which form a thin waterproofing film on their surface. It is permeable to air, effectively repels moisture, but does not interfere with evaporation processes. Waterproofing work is also carried out inside the house, in places where wood comes into contact with moisture.

Decorative processing

Immediately after the construction of a wooden house, its walls are covered inside and out with paints or tinted protective and decorative agents. They can be applied directly to the surface. Or spread over the primer on a similar basis. Finishing wood protects it from UV radiation and moisture, and also improves the aesthetic perception of the object.

When building from glued beams, Garden House uses Tikkurila matte covering paints for the exterior treatment of houses. They are acrylate coatings with oil, which decorate the facade and create additional protection for wood from harmful factors. These coloring agents adhere strongly to the surface and subsequently do not peel off. It will not be necessary to repaint the cottage in a year or two, since when using Tikkurila paints, you can forget about the cosmetic repairs of the facade for at least 7 years.

Properly processed from the outside, a wooden house will last for decades, while maintaining an attractive appearance, strength, and the quality of natural material.

Based on statistics, country houses are mostly built from wood, despite the existing large range of other building materials. From logs in a short time you can build a beautiful and comfortable house of any size and shape. But do not forget that natural wooden material is subject to various destructive influences from biological agents and nature itself, which it alone cannot resist. And to protect the logs, it is necessary to carry out phased processing using chemical protective impregnations, which will significantly extend the life of the log house.

Expert opinions

Processing a log cabin should be done in the following order:

1. An important and first step in the processing of a log house is to clean the crowns. Their surface should be carefully sanded, freed from debris, dust, because. they can prevent the penetration of the protective composition into the structure of the wooden material
2. Then, treat the logs with an effective, high-quality antiseptic composition that can protect the material from the formation of biological agents and insects. Apply the product to the wooden surface at least 3 times, allowing each previous layer to dry thoroughly.
3. The next stage of processing is carried out using flame retardants. They need to be applied to the walls of the log house inside and out in several layers. Depending on the composition used, the wooden surface will become non-flammable (acquiring 1 fire resistance group), or hardly flammable (acquiring 2 fire resistance group), i.e. the material may ignite, but the fire cannot be sustained and propagated. In the event of a fire, a wooden frame treated with flame retardants will turn black, the protective layer of fire retardant impregnation on the surface of the logs will be charred, but it will not burn. Such wooden material is easier to restore than a completely burnt structure.
4. Then the log structure must be treated with water-repellent compounds. Wooden material absorbs moisture well and retains it.
   and from excessive moisture, the logs begin to deform, cracks form on their surface and, most importantly, there are great chances for the formation and further dangerous development of putrefactive processes. Particular attention during processing should be paid to the ends, through their open longitudinal fibers, moisture is absorbed more easily and in large quantities. Apply a water-repellent composition to the end of the log should be at least 4 times.
5. The next stage of processing is the application of a primer. This, in fact, is the final protection of the material from biological troubles. The primer composition penetrates well into the wooden material and eliminates all cracks in the structure. Its main purpose is to ensure good adhesion of paints and varnishes to wood.
6. The final stage in the processing of a wooden frame is the transformation of its appearance. For this, there are special paints, varnishes, etc. Compounds with a bleaching effect are often used to eliminate the darkening of wood.

Complete processing of a log cabin should be done after the wooden walls have dried. Until this time, you can use gentle, so to speak, temporary antiseptics with a short duration. They are washed out with water over time and after a few years their protective effect is greatly reduced. But for the first time, such funds are capable of protecting the structure and residents from mold fungi. These pests not only reduce the performance of the wooden material, but also harm the health of the residents of the log house. Suddenly, respiratory problems (laryngitis, tracheitis, and even asthma) can begin, allergic diseases often occur.

Why are the stages in the processing of a log house important?

Any stage of processing should not be neglected, otherwise, as a result of construction, it will not be possible to build a beautiful, durable and safe log house. To apply protective compounds, use hard brushes with synthetic bristles, natural bristles may suffer during application. Brush movements should be clear and hard, as if rubbing the impregnation into the material, only then the logs will be reliably processed.

On sale there are protective means for processing a log house of domestic and foreign production. They have no special differences. For example, our protective compositions of the Neomid and Prosept companies intended for wooden housing construction are not inferior in quality to foreign imported compositions. After all, the same components, identical modern equipment and technology are used to create them.

Before implementation, specialists conduct a lot of tests, strictly controlling the compliance with the declared properties with the real ones. But at the same time, the cost for them is several times lower, because. there are no costs for the export of funds to Russia.

Separation of funds by purpose

There are narrow-purpose tools aimed at combating specifically mold, rot, or insects. But there are also complex compositions capable of providing protection against several types of pests at once.

A photo: Bio-protective composition of the highest quality Neomid Super Proff 001.

For example, flame retardants of the same companies Procept Firebio Prof and Firebio Prof-1, Neomid 450 and 450-1, they cope with biological pests, and at the same time prevent the ignition of wooden material.

A photo: Fire bioprotective composition of the highest quality Neomid 450-1. It is recommended to use it for floor beams and for processing a wooden truss system of a house of any design.

But it is undesirable to use only this composition. It is better to treat the log house separately with antiseptics and fire retardants separately, so the protection period will be longer, about 20 years. And complex products provide biosecurity for an average of 5-7 years, so saving on formulations is not recommended.

Good antiseptics and reliable antiseptics are Neomid 400, 440 eco, 430 eco, Procept Interior, Exterior and Universal. Each of these compounds should be used strictly for their intended purpose (indoors or outdoors). Indelible antiseptics can be used to treat the lower rims, terraces, gazebos and other structures that are outdoors and are subject to constant negative effects. Their composition is the most powerful and strong.

A wooden house gives people 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 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 the woody structure, where they are nourished and warm, make their contribution. Treating a wooden house from the outside with special antiseptic agents that protect the tree from the negative effects of natural and biological factors will help prevent destructive processes.

Living in a house made of untreated wood lumber is dangerous for humans, because fungi and mold appear on the wood, which are harmful to health, bugs that eat wood settle, and decay processes begin to develop.

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

Any, both new and old wooden house needs processing. There are three stages of processing for a new building:

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

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

How to process a log house from the outside? The answer to this question depends on what tasks need to be solved with the help of processing. There are several groups of funds 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 decay, and also effectively fight existing foci of biological damage.

Antiseptics are presented in two forms:

• Impregnating hard-to-wash compositions. Impregnations are deeply absorbed into the wood structure and are not washed out for years, protecting the wood from biological influences.
• Cover preparations. After treatment with these agents, 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 agents. Designed to brighten wood. The preparations bleach the areas covered with a blue bloom, and at the same time destroy the fungi that cause the wood to darken.
2. Flame retardants. Give wood resistance to open fire. A wood surface treated with this agent does not ignite instantly, as untreated wood usually ignites, and can withstand an open flame for several hours.
3. Preservative impregnations. Ensure the safety of wood. Impregnating compounds are responsible for the smoothness of the surface, prevent cracking and the formation of irregularities.
4. Primers. Primers have protective properties, protecting 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 compositions (varnishes and paints for wood). They are primarily intended for decorative finishing of the walls of the log house, but at the same time they have protective properties.

Outdoor treatment products are used to protect the outer walls of a wooden house, which are constantly exposed to harsh outdoor conditions: ultraviolet radiation, precipitation, temperature changes.

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

It should be noted that many types of antiseptics intended for external work have a persistent unpleasant odor and contain harmful components. For external compositions, such indicators are acceptable, however, when working with them, care should be taken and protective equipment should be used.

There are products for a wooden house that combine different properties: they protect wood from decay, 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. The best result can be achieved when using several highly specialized tools.

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 contribute to a deeper penetration of the antiseptic into the structure of the tree.

Concentrated products are much more expensive than factory-diluted products. However, the consumption of the concentrate is an order of magnitude less than the composition ready for use. Using a concentrated preparation, it is necessary to dilute it strictly according to the manufacturer's instructions.

To decide how best to process wood, you need to take into account the following factors:

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

1. Primary. Carried out by lumber manufacturers or carried out during construction. It is especially important to properly process the elements of the log house that are in contact with the soil, because. they are exposed to moisture more than other parts. These are the lower crowns of logs, piles, rough floors, foundation, outer and inner walls of the basement.
2. Preventive. Healthy wood is subjected to such treatment in order to prevent the formation of mold, fungus, insects and to prevent decay processes.
3. Therapeutic. Processing is performed on a tree that has foci of biological damage. Remedies stop decay, kill fungus and mold that have penetrated deep into the layers of wood.

Please note that preventive agents should not be applied to diseased wood. Preventive antiseptics cover the tree with a film, under which microorganisms will continue to quietly multiply. Therapeutic agents can be applied as a preventive measure in the event that the operation of the house is expected in adverse conditions.

Stages of external processing of a wooden house

The processing process consists of the following steps:

1. Applying an antiseptic. A deep penetration antiseptic is used, which is applied in one of three ways: with a roller, wide brush or spray gun.
2. Treatment with a fire retardant is carried out two weeks after applying the antiseptic. Usually 3-4 coats are required for effective protection.
3. Finishing is carried out no later than two months after antiseptic treatment, since the protective agent can be washed off by precipitation. Finishing options: exterior walls can be varnished or painted, decorative plaster can be applied or the surface can be sheathed 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 with protective equipment is of particular importance when it comes to the ends of a wooden house.

Protective compounds create a breathable film on 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 not recommended. It is recommended to use oil-based or water-based products, for example, Belinka's water-soluble antiseptic has proven itself well.

If the ends have deep cracks affected by fungus and rot, a deep penetration compound must be used. It is advisable to treat with preparations that change the tone of the wood, so it is easier to control the degree of application.

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

Features of wood treatment with an antiseptic

The antiseptic is applied only after cleaning, grinding and degreasing the treated surface.

It is best to start processing the exterior walls from the shady side of the house. First, treat damaged and problem areas.

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

It is not worth processing a winter frame from a bar of natural humidity 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 not lower than 10 degrees.

Processing a house from glued laminated timber can begin immediately after construction, regardless of the time of year.

Difficulties of self-processing

It seems to many owners of wooden houses that the antiseptic treatment of the outer walls of a log house is an easy and simple job. Indeed, if you look at it, then there is no difficulty in processing with an antiseptic, but only if knowledgeable and trained specialists who have repeatedly carried out the treatment and know all its subtleties are taken to work.

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

Home masters make other unforgivable mistakes:

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

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