How and what is better to process a log house inside with your own hands. What is the right way to process a wooden house inside? Which antiseptic for wood is better to choose: calculation and methods of treating wood with an antiseptic What kind of impregnation to treat a wooden house outside

Content:

A house built of timber attracts with its appearance. In addition, this structure has excellent technical characteristics. In order to keep the beam for many years in good condition, it is necessary to properly process the walls outside and inside. And how to process a wooden house from the outside you will learn from the article. To date, there are various antiseptics that will cope with the task.

What has a detrimental effect on wood

Among the most basic enemies of wood, it is worth highlighting moisture in all options. Rain, snow, steam destroy the structure of the fibers, in addition, mold begins to appear. Such an impact significantly reduces the service life of even the highest quality wood. That is why wood impregnation should be used.

Ultraviolet exposure does not affect the structure of the tree in the same way. The beam under the sun's rays does not rot, but the appearance is lost. The top layers of the material begin to darken, becoming a gray, dull color that no one likes.

An equally important factor is the moisture content of the wood. For the construction of houses, it is necessary to use dried and prepared timber.

But in practice, houses are built from under-dried material, which, after drying, begins to deform and burst. Given all the factors, we can say that it is not only recommended, but mandatory.

The main types of products for processing wooden houses

Processing a wooden house involves the application of special tools that will increase the life of the material. Today, all antiseptics that can be purchased at the store are divided into 4 groups:

• antiseptic;
• fire retardant;
• preservative;
• protective finish.

Antiseptic primer

The antiseptic primer is designed to protect the timber from the occurrence of mold, the reproduction of insects that can damage the wood. This effect is achieved by the content of acid, concentrates and alkali in small proportions. Such a primer can be washed out and not washed out.

Fire bioprotection

Fire-retardant impregnation contains a special anti-foam component. It is thanks to him that instantaneous ignition is prevented. Even open fire, wood after treatment with such a composition is able to resist for some time. To use such a tool must be used in strict observance of the instructions.

Preservative processing agents can be divided into two subgroups. Impregnation agents are used to preserve the original appearance of wood for a long time. Film-forming impregnation is used to protect wood from moisture.

Impregnation water-repellent

Water-repellent impregnation for wood forms a special film that prevents the penetration of moisture. When processing timber, special attention should be paid to the ends through which the most moisture penetrates.

Protective finishes have a huge number of features. They protect any coating from sunlight, rain, wind. Such a composition is applied from the outside as a last resort. In addition, this material can have a decorative effect.

Wood processing rules

Having dealt with the question of how to process a wooden house, you can begin to work. Before you treat the timber with an antiseptic, you need to familiarize yourself with the rules for performing the work. Only compliance with the rules and technologies guarantees the achievement of a quality result.

• First of all, it is necessary to determine what materials will be used for processing. Most often, the treatment is carried out with an antiseptic and antiperine. Any kind of composition is applied to the wooden surface from the outside in several layers, the main thing is that there are at least two, it is better to do three. In some cases, you can purchase a bar that is externally treated with special means at the production stage.
• after the antiseptics are applied and completely dried, you can proceed to further work. Further used fire-retardant impregnation for wood. For a house built of timber, fire is the worst enemy. It is better to protect yourself and your loved ones in advance by treating all surfaces with an antiperspirant from the outside. When exposed to fire, the treated surface does not ignite, but only char.
• in order to protect the house from the outside from moisture, it is best to use special tools. Water-repellent impregnation is applied in several layers on the surface of the timber from the outside. It is better to apply 2 layers. The ends of the timber must be processed at least 4-5 times, since they are more susceptible to moisture. Treated wood will not deform from moisture.

Processing of a new building and renovation of an old house

The procedure for performing work in each case has its own characteristics. Before processing outside the house from a bar, it is necessary to carry out preparatory work. All stages of processing a new building can only be carried out after the roof has been mounted.

Note! The humidity of the timber before treatment with an antiseptic should be no more than 25%.

In the case of an old house, the order in which the work is done has some distinctive characteristics. First of all, it is necessary to completely remove the old layer of wood. In this case, you can use a grinder to process the timber. It is necessary to control that the outer walls are perfectly even, the fire-retardant treatment will go much better.

After grinding the walls, the antiseptic will go much better

After working with a grinder, remove all dust and debris from the surface. A vacuum cleaner does a great job with this task. Before treating the timber with an antiseptic, it is worth testing the product on a small area. In winter, such treatment cannot be carried out; to work with any antiseptic, you need to choose sunny weather with a temperature regime of at least +5 degrees. This allows all applied layers to dry evenly and gain the necessary strength.

Is surface priming required?

Wood protection consists of three main stages, after which you can start priming the surface.

The primer is necessary in order to be able to carry out further finishing work. In addition to the fact that the primer increases the adhesion between materials at times, it closes all the pores from the negative impact.

Priming is necessary to improve adhesion between layers of paints and varnishes

The beam at the final stage is treated from the outside with a special bleaching agent. It makes wood look great. Depending on what kind of finishing will follow, the final processing depends. It is also possible to coat the wood with a special wax.

High-quality processing guarantees the preservation of the attractive appearance of a wooden house. But most importantly, the house in this case will last much longer. The impact of the environment in this case will not be so destructive.

When performing all work, it is imperative to strictly follow all instructions from manufacturers, which are indicated on the packaging. It is also recommended to take the advice of experienced craftsmen who know all the subtleties in performing such work. And only in this case it is possible to obtain a high-quality result for a long time, while it will not be necessary to carry out repair work in the near future.

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 a rapid exchange of oxygen. In such a house there is always fresh air, a comfortable environment and a cozy atmosphere.

Logs are easy to stack, which reduces installation time. Due to their low 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 have a significant disadvantage. Wood is a natural material that is exposed to the negative effects of the environment. The sun's 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 process the log house inside and out with the help of various means.

Why do we need to process the log house from the outside

• Protects wood from destruction;
• For a long time it retains the original appearance of a bathhouse or a log house;
• Prevents the appearance of fungus and rot;
• Interferes with influence of insects and moisture;
• Increases the service life of a wooden house or bath;
• Improves the aesthetic qualities of logs, if necessary, you can change the appearance of the facade, get the desired color, shade or shine;
• Fire retardant treatment is a must for a log home, as fire is a significant threat to timber.

What means to choose

Today the market offers a lot of tools for processing a log house inside and out. It is important that they are environmentally friendly and retain 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 funds that will be needed to process the house from the outside:

1. Antiseptics are deeply absorbed into the wood, increasing the resistance of logs to moisture and microbes. Among antiseptic agents, wax, protective varnish and oils are distinguished. They destroy mold and blue.
2. Flame 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 instantaneous ignition and resist open fire for several hours.
3. Preservative solutions and impregnations keep the wood in good condition. Special impregnating materials keep the surface smooth and even, prevent cracks. And film-forming compounds also create a water-repellent barrier. For these purposes, a primer or wood oils are suitable.
4. Protective finishes are more 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 not allow the wood to darken over time.

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

How to process a log house from the outside

• For the first time, the log house is treated with antiseptics inside and out immediately after assembly. Pay special attention to the processing of ends and logs in contact with the foundation. Antiseptics are applied in two layers;
• Primary processing cannot be desired at temperatures below 10-12 degrees!;
• The next processing is done after the log has completely dried and the log house has shrinked. This takes 6-12 months. This finish implies the final complex and multi-layer processing of the house, which will protect the log for a long time. It is important to apply antiseptics on a dry and clean wood surface!;
• Before processing, the logs are ground to remove the top layer, in which fungus and microbes have accumulated during shrinkage. It will remove the defects of the log and level the surface. Sanding wooden walls is a must for an old house, as it is important to completely remove the old coating;

• Processing with a brush will take a lot of time, but it will become the highest quality, most effective and durable. Spray guns are used to speed up the process. 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 flame retardants in one or two layers and also left to dry. The next layer is a primer. It will protect the wood from cracking and level the walls;
• Carefully process the ends. These parts of the logs absorb moisture faster than others, and therefore are more prone to rotting. To avoid this, each end processing 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.

How and how to paint a log cabin outside

Painting is the final stage of processing the log house outside and inside. Today there are many different paints and varnishes. For outdoor painting, choose rough and resistant compounds. 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;
• Covering opaque varnishes will help to achieve the desired shine and shade, protect from insects, high humidity and ultraviolet radiation;
• Oil paints penetrate deep into the structure of the log, keep the surface from moisture and dirt. But they dry for a long time (two weeks) and eventually lose color !;
• 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 even surface, retain their color for a long time and provide protection against moisture. However, such products do not allow the wood to "breathe", which eventually causes the log to dry out and crack;
• Yacht varnish is suitable for places with high humidity and heavy rainfall. This is a reliable protection against moisture, which is not affected by the weather and temperature extremes. Such a varnish does not fade and prevents yellowing of wood, however, when painting, 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 pattern of wood and makes the color more saturated. However, stain requires subsequent varnishing;
• Oils and waxes are eco-friendly, safe products that are deeply absorbed into the wood and protect the logs from moisture and dirt. Wax will give the surface a translucent matte sheen.

To qualitatively paint the log house, wait for the primer to dry completely. Stir 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 - a brush.

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

After complete drying of the paint, varnish is applied in two or three layers. For an even coverage without buildup, let each coat dry, applying the product in long, even strokes. For a 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 operational life of the wood.

Wood is one of those materials that needs special care. Processing a wooden house is required, otherwise the walls will fade, become saturated with moisture and begin to rot, and a fungus will appear inside the house. Consider what means to choose to preserve the quality of the tree outside and inside the house. How to process a wooden house?

Wood, as a material for building a house, helps to create a special atmosphere and comfort. It allows the walls to breathe and promotes air circulation in the room. In addition, wood has high energy saving rates. The wooden house looks very beautiful due to the naturalness of the material.

But, the tree is very whimsical to care for. Its features include:

1. It absorbs moisture well. Temperature fluctuations and high humidity affect it especially adversely, it either swells or shrinks, as a result of which it loses its structure, can crack and rot. And this leads to the destruction of the walls.
2. Another feature of wood as a natural material is its susceptibility to the action of microorganisms such as fungus, insects and algae. Dark or gray spots, as well as mold, may appear on the surface of the walls. The fungus can lead to the destruction and deterioration of the tree in a very short time.
3. Under the influence of UV radiation, the wood begins to lose its color, it turns gray, the structure becomes porous and rough, which increases the ability to absorb moisture.

As you can see, the tree is exposed to any weather conditions and quickly becomes unusable. In order for wood to retain its appearance and last for many years, it must be treated with protective agents. Consider how to process a wooden house.

What processing aids are available?

Processing a wooden house is needed to protect against adverse factors. The effectiveness of protection depends on the quality of the selected means. This issue should be taken with particular seriousness, especially if you choose means for processing outside. To preserve the appearance of the house, oil-based protective agents are best suited. They will significantly extend the life of the coating.

Consider high-quality materials for processing outside:

1. Holzwachs Lasur wax coating. Formulated with natural waxes and urethane oils, this coating provides UV, weather and insect protection. The agent forms a protective film, which in no way spoils the view from the outside and does not look artificial. The tool can be chosen transparent or colored. There are 8 colors.
2. Oils Borma Wachs. This agent is suitable for treating terraces, as well as flooring, which is constantly subjected to wear and friction. Danish oil has excellent wear resistance. For processing, you can choose oils without solvents, for example, teak or tung. They do not contain any additives, are well absorbed into the wood and protect it from UV radiation and weathering.

Undoubtedly, it is products based on wax and oil that best protect a wooden house from the outside. And how to process the walls inside a wooden house?

For interior work, you can choose water-based antiseptics or special chemicals.

Popular antiseptics

How to process a wooden house? There are a huge number of antiseptics. It will be very difficult for a person who understands little in the processing of a wooden house to decide on the choice of means. We offer the most popular and proven antiseptics to protect the house inside.

It is possible to single out the antiseptic company Senezh, produced in Russia. This tool increases the fire resistance and moisture resistance of wood. Also, with the help of the tool, you can bleach already damaged areas on the surface.

If the tree has already been treated with varnish or drying oil, then an antiseptic cannot be used.

In second place in terms of their protective characteristics, one can single out the antiseptics of the Neomid company, also of Russian production. They perfectly protect wood from microorganisms and increase fire resistance. Moreover, such tools are suitable for both finishing inside the house and for outdoor work.

Firm Neomid presents washable and non-washable antiseptics, as well as oil paints.

Antiseptics of the Belinka trademark will protect from atmospheric influence. They are more used to protect the house from the outside. The products allow you to preserve the natural color of the tree and are suitable for any species.

To impregnate wood and protect it from moisture, you can use Aquatex paint. Moreover, the color scheme is represented by 15 colors. The paint is environmentally friendly, since it does not contain harmful substances, so it is ideal for treating walls inside the house.

A good choice of protective antiseptics that increase the fire resistance of the coating is presented by Rogneda. The funds provide protection for at least 15 years. It is important that antiseptics can stop the development of the process of decay that has already begun as a result of damage by mold or fungi.

For treatment inside the house, water-based antiseptics from Aquacolor are suitable. They are inexpensive and allow you to lighten the darkened wood.

Tikkurila antiseptic is suitable for outdoor work. It protects against moisture, mold and UV radiation.

Processing inside and outside the house

For the treatment of wood inside the house, as a rule, water-based antiseptics are used, they do not have a strong odor and are absolutely harmless. They also do not allow moisture to pass through, but allow the tree to breathe.

The processing technique is as follows:

1. Apply antiseptic in one layer. Complete drying occurs after 9-18 days.
2. After the antiseptic has dried, apply an impregnation that increases the fire resistance of wood.
3. If there are dark spots on the wood, then a bleaching agent must be applied.

Impregnation for wood can be salt and non-salt. Salt ones provide a lower degree of protection against fire, but are cheaper. Non-salt ones are more reliable. It is possible to distinguish the impregnations of Pirilax and Neomil firms.

After treatment with an antiseptic and impregnation, the walls can be painted. To do this, you can choose a varnish or paint, they will also provide additional protection against mechanical damage.

External processing is slightly different from internal, because the tree outside the house is exposed to weathering and more dampness.

Processing outside:

1. Applying a water-based antiseptic. It is best to choose a tool for deep processing, it penetrates well deep into and protects against dampness and decay.
2. Application of flame retardant. Two weeks after applying the antiseptic, the tree is treated with impregnation. It is better to apply the product in 4 layers.
3. Finishing. It can be produced using top coats that hide the structure of wood and glazing antiseptics, acrylate or oil paints. Walls can also be plastered. Before applying finishing compounds, the surface must be sanded, a solution to remove tar stains should be applied and cracks and irregularities should be puttied.

By adhering to all stages of processing and choosing only high-quality products, you can preserve the natural look of the tree for a long time.

Treatment of wooden walls with protective compounds

The owners of wooden houses are well aware of their "diseases" - mold, fungus, insects, rot, etc.

Do not believe those who claim that in Russia wood products were not treated with protective agents. Linseed oil, resin, saturated saline solutions, and lime were actively used.

In Soviet times, they were replaced by drying oil, blue vitriol, waste oil. But progress does not stand still. The modern chemical industry offers a huge range of products for treating a wooden house from the outside.

Why does wood deteriorate?

The first enemy of a new house made of timber is water in all its manifestations.

Rains, snow, ice destroy the fibers, rot appears, fungi and antimycetes multiply.

And if mold and moss can be actively fought, then decomposition processes cause much more harm - a rotten log is no longer good for anything.

Wooden frame, struck by the "blue"

Another issue is ultraviolet light.

Under the influence of sunlight, the wooden surface on the outside begins to darken, acquiring a dull grayish tint. However, most still prefer the soft amber-golden or dark honey hue of a freshly cut tree. And it does not matter that the effect is actually achieved artificially with the help of appropriate processing. It is not only fashionable, but also really very beautiful.

The next group of problems is related to wood moisture. The fact is that rarely is a house built from dead wood.

The used wooden beam reaches the "condition" in the finished building for almost a year. During this period, the logs crack, twist, dry out, gaps appear between them, etc.

The process is natural, but who said that it cannot be influenced?!

Thus, processing becomes not only desirable, but a necessary means of protection against all sorts of problems.

How to process a wooden house - types and types of compositions

Home processing is the application of special protective and priming compounds that ensure the safety of the tree for many years.

The main goal is to improve performance and extend service life. There are 4 groups of funds:

1. Antiseptic - primer compositions containing fungicides that prevent or destroy mold spores, blue stain, bugs and bark beetle larvae, woodworms, and other insects that destroy wood. They contain acids, alkalis, special concentrates in small doses. They are divided into washable (transport) and non-washable.

Antiseptic impregnations are most often produced in cans

Common brands: Neomid, Senezh, Belinka, Remmers. Treatment with an antiseptic is carried out in 1-2 layers, it is advisable to observe personal safety measures (gloves, glasses). Re-treatment of the house (if no decorative coating is applied) is recommended after 3-5 years.

Fire retardant - special compositions with flame retardant additives.

Prevent instant ignition, allow you to resist open fire for several hours.

How to process a wooden house outside

In practice, a tree impregnated with fire protection simply smolders. Produced under the brands Pirilax, KSD, NORT, Glims Ognestop. Apply generously in one layer in accordance with the instructions.

Pyrilax protects the tree from fire

Finishing protective compositions produced by Belinka and TEX

It should be noted that recently the so-called vapor-permeable protective and decorative products (Tikkurilla, Dulex) have been actively promoted.

That is, a layer of paint allows the tree to “breathe”, while at the same time protecting it from water.

Separately, it is worth highlighting the painting material with a hydrophobic effect. It is applied to the ends in a dense layer and forms a durable waterproof film.

For the convenience of buyers, manufacturers of paint and varnish products have developed tools that can be combined into a separate group - universal primers for processing a wooden house from the outside. These are complex products containing fungicides, flame retardants, saline preservative solutions, etc.

"Fire bioprotection" from CJSC Rogneda, a series of "XM" from the Yaroslavl antiseptic and many others. Although, according to experts, it is better to use narrowly targeted formulations.

In what order are the ingredients applied?

If the wood is in good condition, you need to start with fire retardants, then preservative treatment, preservatives are used before applying the finish coat. If the tree is damaged by bark beetles or mold, then a primer with active fungicides (Neomid, Pufas) is first applied, then flame retardants (although some prefer to do without them altogether).

If the tree is already affected by insects and there are probably bark beetle larvae in the depths, this scourge must be fought radically.

It is not enough just to brush with an antiseptic. Firstly, a separate agent is required (Antizhuk, Lignofix concentrates), and secondly, the application methods are different - injection or intensive spraying.

Of course, we did not include tinting, putty and other products responsible for decorative design in the list.

Their use is dictated only by the taste and needs of the owners of the house.

The order of work on the processing of walls

External processing of a new building begins after the erection and installation of the roof.

Desirable wood moisture content is not more than 25% (measured with a contact or non-contact moisture meter). It is carried out in 4 stages.

The fact is that some products have tinting properties, that is, the house can acquire a completely unexpected shade (from pistachio to brown). This rule must also be observed in relation to glazing (transparent) paints and varnishes.

For a painted house, the process is different:

1. Surface preparation begins with the removal of the old paint layer with sandpaper, a spatula, a grinder, special gel products - washes for paintwork materials;
2. The cleaned surface must be dusted with a vacuum cleaner and wiped with a damp cloth;
3. Prime with a composition with fungicidal additives in 1-2 layers;
4. Carefully move the varnish or paint, add thinner if necessary and apply 2-3 times with an interval of at least 48 hours between coats.

Complete exterior processing of a wooden house is an incredibly time-consuming process.

This takes a lot of time and money. But you should not be sorry and lazy - the service life of the building, its safety and beauty depend on your actions.

Wooden housing construction is gaining momentum in our country, because it has become clear to many people that living in a wooden house is much more profitable than in cages of multi-storey high-rise buildings. Today it is prestigious and reasonable to have even an inexpensive country house. The acquisition of an ecologically impeccable ark outside the aggression of the metropolis for many generations of the same family is the main trend of recent years. Only the house needs to be protected, taken care of, and the main issue in this matter is the need to protect it from decay.

What is wood decay

This is the process of destruction of cellulose under the influence of wood-destroying fungi and microorganisms.

The better to process a wooden house and an extension from the outside

On the other hand, in warehouse sheds, felled wood is threatened by warehouse fungus and sleeper fungus, and in areas by house mushrooms. These latter readily destroy organic materials, including reeds, fiberboard and others.

The most dangerous among them has a beautiful name - the white brownie, the diaper mushroom and other pests rush to join it. They can be defeated only by creating conditions unfavorable for their existence.

Rotting control methods

Mushrooms love moisture, which means that the building material must be thoroughly dried before construction.

The built house needs to be protected from moisture, waterproofing is required with paints, varnishes, enamels. For constant ventilation of wooden structures, a natural ventilation system is required.

Rains and frosts, and then wind and heat do their bad deed. The wood is moistened, destroyed, to prevent this, the use of antiseptics is required. Chemical preparations, antiseptics, are harmless to humans and animals, but merciless to fungi and mold.

Water-soluble preparations are used for the outer surface of the walls. Such products do not reduce the strength of wood and do not cause corrosion.

Some structural elements that are intensively exposed to water are treated with oil antiseptics. Surfaces located in close proximity to the ground are treated with antiseptic pastes, the paste is applied to the surface and covered with roofing felt, roofing felt and other waterproof materials.

Impregnation is applied with brushes, sponges, spray.

Sealants and fire retardants

The house should be protected from the wind, and from snow, and from any vagaries of the weather, climatic troubles. To do this, seams, joints in a log house are sealed with sealants. By the way, the sealant can become a decorative element if desired, it is enough to give the desired color shade with acrylic paints.

Fire retardants are applied over the antiseptic using rollers, spray guns, brushes in several layers.

After such processing, the house is no longer afraid. Protection against decay can be a high base, waterproofing of the lower crown, but the main means of prevention. A wooden house should be processed at least once every five years.

A wooden house, due to the unique properties of wood, is an ideal dwelling for a person. The optimal level of indoor humidity is maintained due to the hygroscopicity and vapor permeability of natural material, which continues to “breathe” in the walls of the log house. A living structure needs protection from the adverse effects of the environment.

Reasons for the destruction of wooden structures

Natural, technogenic and anthropogenic factors that can affect the integrity and health of the walls of the log house:

• Ultraviolet radiation destroys lignin, which is the reinforcing frame of wood. Under the influence of direct sunlight, the surfaces on the outside darken, become porous, easily absorb moisture and quickly release it. As a result, the logs age prematurely and crack.
• Precipitation and high humidity lead to swelling, and then to shrinkage of wooden structures. Wet wood is a favorable environment for the reproduction of fungal microorganisms and mold foci. The rotting corner of the log house can cause the destruction of the house.
• Insect pests and rodents, which can settle in the walls of the log house, damage the integrity of the tree.
• Exposure to concentrated acid-base solutions affects the chemical composition of the tree and changes its physical properties.
• Fire- one of the most destructive factors that can destroy a wooden frame in a very short period of time.
• Uneven heating of the walls of the house, the formation of condensation on their surface, dry indoor air in winter - all these are the results of human activity, which also adversely affect the condition of wooden structures.

The inevitability of the influence of one or more factors convinces of the need to treat the internal and external surfaces of a wooden structure.

Methods for protecting wood from adverse factors

During the construction phase, use constructive methods of timber protection from exposure to moisture, solar radiation, biological damage and fire. Measures consist in isolating wooden blanks from the ground, arranging well-ventilated sheds at a sufficient distance from combustible materials and open sources of fire. Installation work can take several months, so it is important to prevent deformation and premature destruction of building materials.

Along with constructive methods for wood processing, new generation antiseptics which protect the material from moisture penetration and infection by fungal microorganisms for up to 8 months (for example "SENEZH EUROTRANS").

If, nevertheless, the logs are covered with dark spots of lesions, you can get rid of them with the help of bleaching agents, which include chlorine or active oxygen.

Traditional chlorine bleaches have a negative effect on wood, destroying its structure, so it is better to use advanced technologies that meet world environmental standards. A drug "SENEZH NEO" based on active oxygen does not emit harmful substances and is suitable for the treatment of wooden houses inside and out.

Protective equipment for log processing

Reliable and safe processing of a wooden house depends on what compositions it will be produced with. On the modern market, there are a large number of products from various manufacturers that promise 100% protection against all kinds of effects on wood. The most popular and proven include:

• "SENEZH"- tinting and preservative water-based and acrylate-based antiseptics, fire-bioprotective materials and bleaching agents. Russian production;
• "NEOMID"- antiseptics for indoor and outdoor use, insect and microorganism repellents, fire retardant emulsions of 1 and 2 efficiency groups, fire retardant paint, wood protection oil for baths and saunas. Manufacturer - Russia;
• Belinka- protective primer, colorless antiseptic, permanent impregnation, water azure for lightening, paint with an ultraviolet filter. Slovenia;
• "Tikkurila"- colorless oils and water antiseptics, glazing materials, pigment paints. Protection against moisture, mold, decay and solar radiation. Finland;
• "Rogneda"- safe fire and bioprotective compositions, bleaches and protective and decorative coatings. Active antiseptics destroy the lesions that have appeared and provide protection from 15 to 50 years. Russia.

• means are applied to the cleaned and degreased surface of the log;
• initially treat the lesions;
• allowable temperature for organic compounds above +50C;
• the minimum temperature for using water-based products is +100C;
• maximum air humidity - 80%;
• external processing of walls is best done in the shade of the house and move behind it in the process of work;
• fire-retardant impregnations and coatings are applied after the wall has been treated with an antiseptic.

External treatment of the house with protective compounds

Colorless water-soluble antiseptics are used as a deep penetration bioprotective primer. For outdoor work, it is allowed to treat walls with organic-based compositions (for example - NEOMID 430 ECO or NEOMID 440 ECO).

The facade of the house is most susceptible to the influence of precipitation, so the logs are carefully covered with a protective compound, paying special attention to the end cuts. The lower part of the walls is impregnated with a special antiseptic from groundwater, seasonal flooding, microorganisms and rodents (for example - “ SENEZH").

Then fire protection is applied to the walls. For these purposes, there are fire-retardant coatings and impregnations. Protective paints, pastes, coatings hide the surface of the wood, so it is better to use an impregnating composition that is applied to the wall logs in several layers. For critical areas, the means of the 1st group of fire protection efficiency with control surface tinting are used (for example - NEOMID 020).

Finishing is carried out with coating or glazing antiseptics, which emphasize the structure and color of the log surface. To hide the surface that has lost its original appearance, the facade can be painted with acrylate or oil paint. External coatings should be selected with UV protection (e.g. TIKKURILA WALTTI).

Internal protection of wooden walls and ceilings

They are odorless, do not emit toxic substances, allow air to pass through and are moisture resistant. If dark spots appear on the walls inside the room, they should be treated with active oxygen bleach before applying the antiseptic.

After the first layer of treatment has dried, a fire retardant can be applied to the walls. "Senezh ognebio" complex impregnation of the 1st group of efficiency against fire, protection against mold, blue stain and insects. It does not change the color of the wood and is suitable for the interior.

Decorative finishing of internal wooden surfaces is carried out with glazing coatings or acrylate-based paints that are resistant to mechanical damage, which do not lose their color and gloss for a long time.
