How can you treat the outside of a wooden house? Treatment of wooden walls with protective compounds. Protective means for processing logs

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

Expert opinions

The log frame should be processed in the following order:

1. An important and first stage of processing a log house is to clean the crowns. Their surface should be thoroughly sanded and free from debris and dust, because... they can prevent the penetration of the protective composition into the structure 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 a wooden surface at least 3 times, allowing each previous layer to dry thoroughly.
3. The next stage of processing is carried out using fire retardants. They need to be applied to the walls of the log house inside and outside in several layers. Depending on the composition used, the wooden surface will become non-flammable (acquiring fire resistance group 1) or difficult to ignite (acquiring fire resistance group 2), i.e. the material may ignite, but the fire will not be able to sustain or spread. In the event of a fire, a wooden frame treated with fire retardants will turn black and charred protective layer fire retardant impregnation on the surface of the logs, 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 excess 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. During processing, special attention should be paid to the ends; through their open longitudinal fibers, moisture is absorbed more easily and in large quantities. The water-repellent composition should be applied to the end part of the log at least 4 times.
5. The next stage of processing is the application of a primer. This is, in fact, the final protection of the material from biological troubles. The primer 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 of processing a wooden frame is its transformation appearance. For this there are special paints, varnishes, etc. Compositions with a bleaching effect are often used to eliminate darkening of wood.

Full processing log house must be done after drying wooden walls. Until this time, you can use gentle, so to speak temporary, antiseptics with a short period of action. Over time, they are washed out by water and after a few years their protective effect is greatly reduced. But for the first time, such products are capable of protecting the structure and residents from mold fungi. These pests not only reduce performance characteristics wooden material, but also cause harm to the health of log house residents. Problems with the respiratory system (laryngitis, tracheitis, and even asthma) may suddenly begin, and allergic diseases often occur.

Why are the stages in processing a log house important?

You should not neglect any stage of processing, 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 be damaged during application. The brush movements should be clear and rigid, as if rubbing the impregnation into the material, only then will the logs be reliably processed.

Protective means for processing logs of domestic and foreign production are available for sale. They have no special differences. For example, our protective compounds from Neomid and Prosept, intended for wooden house construction, are not inferior in quality to foreign imported compounds. After all, the same components and identical modern equipment and technology are used to create them.

Before implementation, specialists carry out a lot of tests, strictly monitoring compliance of the declared properties with the real ones. But at the same time, their cost is several times lower, because... There are no costs incurred for exporting the product to Russia.

Division of funds according to purpose

There are narrowly targeted products aimed specifically at combating mold, rot or insects. But there are also complex formulations that can provide protection against several types of pests at once.

For example, fire retardants from the same companies Prosept Ognebio Prof and Ognebio Prof-1, Neomid 450 and 450-1, they cope with biological pests and at the same time prevent the fire of wooden material.

Photo: Fire-retardant composition of the highest quality Neomid 450-1. It is recommended to use it for floor beams and processing of wooden rafter system houses of any design.

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

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

Today wooden house construction V various variations is experiencing a real boom in popularity in the private sector. Log houses, houses made of timber and tongue-and-groove boards or sheathed wooden cash are increasingly found in cottage villages, country and garden partnerships. However, in order wooden facade remained a decoration of the site for years, it requires a certain amount of care, and not after it becomes dilapidated and loses its newness, but immediately after construction.

In this part training course it will be explained why it is necessary to immediately protect the facade, and how this can be done. We will cover the following aspects:

• Damaging factors.
• How to protect a facade in various conditions.
• Materials for facade protection.
• Choosing paint color for the facade.

Damaging factors

Wood natural material, the process of destruction over time is inherent in it by nature itself - according to natural reasons the wood eventually decomposes into harmless components.

From the very beginning of operation, it is exposed to two types of damaging factors.

• Climatic.
• Biological.

Professionals give this definition of climate impacts and highlight the main danger.

Sereda Evgeniy BIOFA specialist

Climatic factors include: ultraviolet radiation, fluctuations in humidity and temperature, wind loads. The main enemy of a tree is the sun, under the influence sun rays lignin is destroyed - the permeability of the top layer increases, cellulose molecules are formed on the surface, the original color fades, and a gray tint appears.

Through the destroyed upper layer the wood begins to be saturated with moisture from the atmosphere, even if the façade was originally built from dried material. Wood with natural moisture is absorbed even faster - moisture saturation can reach 20%, which will provoke bacteriological damage. In addition, regular changes in this indicator as a result of moisture evaporation during heating will gradually lead to warping and more significant cracking of the surface. The wind will only aggravate the situation, promoting the expansion of cracks and introducing dust and spores of pathogenic flora into them. The result will be not only a significant deterioration in the appearance of the facade, but also accelerated aging and loss of strength.

Sereda Evgeniy

TO biological factors includes damage by bacteria, fungi, pathogenic flora (algae, mosses). As humidity increases, wood becomes an ideal habitat for microorganisms and the main danger lies in the fact that the primary infection is visually invisible.

The most common are blue rot, which gradually penetrates to the entire depth and provokes a characteristic coloring of the walls, and mold fungi, which form growths on the surface that resemble dirt on the facade. And if it is still possible to stop further damage to the tree, then returning the façade to its original attractiveness and durability will be quite difficult and costly.

Wooden façade protection

To avoid loss of decorativeness and deterioration of wood characteristics, the facade is treated by special means, protecting both from atmospheric influences and from the danger of bacteriological damage. Manufacturers have developed special wood protection systems, including compositions various actions, since it is complex processing that will give the maximum effect. There are two main types of systems, designed for specific specific applications.

• Intermediate - for preserving wooden unfinished buildings for the winter or for protecting the log house during the standing period.
• Finishing – to protect and enhance the decorativeness of completed facades wooden houses.

Intermediate systems protect against ultraviolet radiation, prevent dampness, cracking and peeling, and damage by fungi and mold. Their use allows you to maintain the presentable appearance and integrity of the facade before the process final finishing. In the future, when finishing facade, such preparation will reduce the consumption of the main coating. Typically the system includes an oil-based antiseptic primer and protective oil for walls, crown logs, joists, bowls of corner joints.

Finishing systems not only protect the façade from negative impacts environment, but also improve appearance. Depending on the specific type of decorative coating, the beauty of the natural structure of wood can be emphasized with a slight increase in the brightness of the shade, or a completely different color can be obtained. Like the intermediate, the finishing system includes a primer and a base coating - oil, paint or varnish. It is recommended to use soil regardless of the moisture level of the wood - dry or wet material, timber or log. But if the house is built from wood with natural moisture, its use is no longer recommended, but mandatory.

Soil based linseed oil penetrates deeply into the surface of the wood, reliably protects the wood from damage by fungus, blue stain and mold, does not prevent moisture from escaping from inner layers logs and is able to protect wood from atmospheric loads for a long time. Also, the use of oil primer will allow you to obtain a more even shade of the surface when treating it with colored products.

Usage complex systems, specially designed taking into account the characteristics of wood and compliance with the processing technology (surface preparation) of wood will give a more lasting effect than simply painting the facade with a product you like in terms of color and cost.

Paints and oils for facades

Due to the specific nature of the application, increased demands are placed on products for outdoor use. They must withstand high and low temperatures, exposure to precipitation and ultraviolet radiation, as well as wind loads (dust storms). When it comes to compositions for wooden facades, specific properties are added to this list:

• Preservation of natural wood texture.
• Lack of aggressive chemicals.
• Formation of an elastic coating that allows the wood to breathe.

Modern compositions for painting wood meet all these requirements; due to the environmental friendliness and durability of the resulting coating, paints, glazes and oils are most popular today, while varnishes have lost their relevance.

Paints – the most popular are paints based on acrylic resins, as they create a vapor-permeable, but resistant to external influences coating. They do not have a strong odor, are easy to use, and dry quickly. If we are not talking about the entire facade, but about zonal painting, ester-based paints are effective vegetable oils and resins. They form an elastic coating with a pronounced glossy sheen, which increases the decorative effect of the facade. Alkyd compositions are gradually falling out of use, since they have minimal permeability and the resulting coating, although resistant to external influences, is short-lived; it will begin to crack and peel after a couple of years, while acrylic will last twice as long.

Lazuri - a type of texture facade paint, but the coating turns out to be glaze (translucent). Azures combine the effectiveness of impregnation and varnish - they penetrate deeply and form a silky, elastic coating. They are produced on various bases, but the most environmentally friendly and safe ones are water based. On sale are mostly colorless azures, which can be tinted in any shade you like, from pastel to bright, saturated ones.

Oils – penetrate deeply into the wood structure, creating a breathable, durable, elastic, water- and dirt-repellent surface.

Choosing a color for painting the facade

The main function of painting a wooden facade is to protect it from weathering and solar radiation, so the oil must be colored.

Sereda Evgeniy

For external works Only colored or tinted compositions are used, this way the greatest protection of wood from sunlight is achieved. The more intense the color, the stronger the protection against fading.

Considering that in addition to the protective properties, coloring is also an opportunity to increase the decorative effect of the facade, color has great importance. The correct choice of color determines whether the facade will look organic and pleasing to the eye, or whether you will have to avert your eyes and urgently find funds for remodeling. When choosing a color, take into account the following nuances.

• The beauty of wood is in its naturalness - facades of natural, bright or pastel colors simulating various varieties– all shades of brown and honey.
• Dimensions of the building - visually a light color scheme increases the volume, and a dark color scale reduces it. Large houses can be painted in any tone, while small ones are more suitable for light ones.
• Region of residence - so that the house does not blend into the general background, for southern latitudes choose a color from cold colors, for northerners - warm.
• General style - the color of the facade should be combined not only with the color of the roof and decor, but also with the color of other buildings on the site. You need to be careful with contrasts to get good combination, not a rainbow.
• Lighting – sunny areas look brighter, shaded areas look dull.
• Consumption - even when using a primer, wood has a high absorbency and will most likely require several layers to obtain a rich color.

Today, the problem of choosing a color for a facade is successfully solved thanks to various online services that allow you to see in advance how a particular shade will look or how it will combine with other elements. The final result after application to the wall will differ from the picture, but you can get a general idea. In addition, many paint and varnish manufacturers provide color selection services in sales centers or on official websites.

A wooden facade, properly painted with materials suitable for its properties, is reliably protected from external negative influences. Modern systems protecting facades makes it possible to maximize the service life between treatments, and updating will require minimal financial investments and costs.

All types of wood need additional protection, because the wood is very susceptible to negative impacts, such as:

• high level humidity;
• sudden changes in temperature;
• exposure to the sun, etc.

But it is also worth protecting the wood from insects and rodents, fungus and mold, which can completely destroy the structure of the tree.

Surface treatment wooden house outside

So what is the best way to cover a wooden house so that it lasts for many years? Today it is easy to cope with this problem, because you can find various impregnations on the market for this. These include not only antiseptic substances and flame retardants, but also paints and varnishes, various waxes and other impregnations that will highlight the decorative properties of wood and ensure its protection and long service life.

Processing wood with specialized compounds allows you to:

• protect the wood from moisture penetration into the finishing structure;
• form a thin film on the surface of the material that will allow air to pass through but will not allow moisture to be absorbed;
• protect the base from harmful influence rays of the sun;
• keep the tree untouched by insects and fungi;
• prevent flames from growing during a fire;
• add visual appeal to the building, etc.

What products are there for treating a wooden house?

Processing wooden house on your own

So, how to process wood and what is best to use for this? The solution to this issue is not as difficult as it seems at first glance.

Wax is used to extend the shelf life and transform the appearance of a building. It is applied in a couple of layers, for which only the liquid consistency of the substance is suitable.

Natural oil is best used to protect the surface from exposure to sunlight. This substance is odorless and covers the surface in 2 or 3 layers with an interval of ½ day. Complete drying occurs within a day. You can dissolve the oil with turpentine, and the consumption of the substance is 1000 g per 10 m2.

Danish resin oil is used only for exterior work. After treating the surface, it is covered with a transparent film, which initially smells a little. The substance must be applied in two layers with an interval of half a day. The surface dries out after a day. Please note that the oil must be diluted with turpentine before use.

To treat a wooden surface you need:

1. choose the most suitable substance;
2. treat the surface with an antiseptic solution;
3. coat the wood with fire retardant;
4. protect from ultraviolet rays and moisture;
5. apply primer or varnish;
6. cover the product with wax.

Antiseptic substances

Self-external treatment

Typically, upon completion construction work a house made of wood needs to be coated with antiseptics, both inside and outside. It is better to carry out such processing in a factory environment, but if this is not possible, you can do the work yourself.

The classification of antiseptic substances is given in the table.

Basically, antiseptics are manufactured at water based that do not block air penetration. After such finishing, as a result of the surface drying, no odor remains.

In order for the antiseptic substance to cover the product efficiently and evenly, the coating should be carried out in several steps. To do this, the material is covered with a special substance in a couple of tiers, and then flame retardants and water-repellent substances are used. This technology helps to firmly protect the surface and can compete with factory processing.

How should wood be processed?

We process a wooden house

So, how to treat the lining inside and outside the house? To do this, you should adhere to a certain technology.

The wood processing process is similar for all substances, but working with antiseptics requires special care.

It is better to perform the work in the following sequence:

• Decide which product you will use. Basically, substances are used that can protect wood from putrefactive changes and burning. The substance is applied with a brush or spray in 2 or 3 layers. It is worth starting the processing from the outside, and then proceeding to the internal work. If you don't want to get your hands dirty, you can purchase wood that has already been properly processed in the factory, but additional protection it won't be redundant.
• Antiperen, which protects your canvas from burning, should be applied in two layers after the surface has been treated with antiseptic substances. Antiperen is able to penetrate deeply into the structure of the material, after which it is not afraid of even direct contact with fire. On shelves today construction stores you can see different analogues of such a substance, which are developed for specific purposes. But, it is necessary to take into account that the material may become charred, but direct combustion will not occur. Of course, not only wood can ignite from prolonged exposure to fire, but it is the fire retardant that makes it possible to extinguish the flame in time and prevent its distribution over the entire surface.
• The third layer with which the wood is treated is protection from moisture, because the house should not absorb water. For such purposes, impregnations with a water-repellent feature are most suitable. Such a substance should evenly and thoroughly cover the entire wooden surface; special attention should be paid to the ends. It will be enough to treat the sides of the log with two layers of impregnation, but apply the substance in 4 or even 5 layers to the ends. This treatment will allow the wood to dry quickly, and the moisture will evaporate evenly, which will not lead to deformation of the wood.

If a wooden structure is properly treated inside and out, it will shrink evenly in the future, as a result of which you will be able to avoid the appearance of cracks, distortion and large gaps.

Why use soil?

Upon completion of applying protective substances to the wood, the surface must be treated with a primer, which will serve as a preparation for subsequent work. For these purposes, you can use alkyd-acrylic primer, which is able to penetrate deeply into cracks and “seal” them. It is through the use of a primer that you will achieve a high level of adhesion. The soil can be used both outside and inside the house.

At the end of all the work, the wooden building should be coated with a bleaching mixture, which will externally transform the wooden materials.

If there is a need or even an urgent need, the tree can be treated with other materials, such as wax. This framing adds attractiveness to the wood and extends its service life. There is no need to apply paint anymore, because the appearance is quite beautiful and does not hide the naturalness of the finish.

As you can see, processing a wooden building requires the use of specialized substances that differ different features. Be especially careful when choosing an impregnation that can protect the material from mold and fire.

In this article we will tell you how to treat a wooden frame to protect it from environmental influences.
What to cover garden furniture and terraces in a country house, how to give the surface the color you need and how much material you need to buy for finishing.

And also about all materials for outdoor work.

Why treat a wooden house?

Wooden surfaces located in the open air, be it a wooden facade, decking, gazebo or pergola, are subject to constant exposure to the environment. Precipitation, UV radiation, wind, various fungi and microorganisms, constant changes in humidity and ambient temperature can quickly render wooden products and surfaces unusable.

For example, under the influence of sunlight, UV radiation causes the process of graying of wood (one of the components of wood, lignin, is destroyed), it becomes rough and porous. In this state, the ability of wood to absorb moisture from the environment sharply increases. When the temperature and humidity conditions change, wood changes its geometric dimensions both more (swelling) and less (shrinkage). As a result, both the appearance of the wooden surface and the structure as a whole are deteriorated (tearing out fasteners from the board, etc.).

How to treat a wooden house?

Processing a wooden house involves high-quality wood protection - which is a necessary condition to maintain an attractive appearance and long term service of wooden surfaces located in the open air.

In each case, check the stages and sequence of coating with our specialists - they may differ, since the type of wood and tasks are different for everyone!

1. Wax coating Holzwachs Lasur

This coating, based on urethane oils and natural waxes, penetrates deep into the wood and provides reliable protection from UV radiation, atmospheric exposure and insect pests.
Holzwachs Lasur forms matte film, abrasion-resistant, which looks natural and does not give the effect of artificial varnish. The material has a mild solvent odor.

The coating is used as the first step before oil in creating an individual color, in painting a wooden house or other structures, be it a bathhouse or an outbuilding.

Has a transparent option and a row colors : also possible tinting according to RAL catalog !

Buy wax coating you can in the category Waxes in the Online Store .

How to apply:

The wax coating is applied in 2 layers with an interval of at least 8 hours, complete drying within 24 hours.


Wax impregnation has the form of a liquid and is sold in the following standard containers: 0.75 ml., 5 l., 20 l.

2. Teak and tung oils

This natural oils without chemical additives that impregnate the wood and protect it from UV radiation and atmospheric influences.
Oils form an almost invisible natural film that does not change the color of the wood. The material is odorless.

How to apply:

Teak oil is applied in 2-3 layers with an interval of at least 12 hours, complete drying in 24 hours.
Application method: roller, brush or spray.
The oil is ready for use; if necessary, it can be diluted with an oil solvent or turpentine.

When applying the first layers, it is recommended to dilute tung oil with turpentine or solvent in a ratio of 4/1 solvent/oil, subsequent 2/1 and 1/1.
Fully tung oil takes a very long time to dry, sometimes the drying time is 3 weeks. However, subsequent layers can be applied after 12 hours.

Oils are in liquid form and are sold in the following standard containers:
Teak oil: 0.5 l. and 5 l.
Tung oil: 1 l. and 5 l.
Consumption: 1 l per 10-12 sq.m. / 1 layer.

How to treat a terrace or deck?

For treating surfaces subject to wear or floor coverings, we recommend Danish oil. This material has a fairly high dry residue and is resistant to wear.
If you want to use solvent-free materials, we recommend teak oil. You need to apply 3-4 layers.

3. Danish oil

This oil is developed on the basis of urethane resins specifically for outdoor use. When applied, it creates a transparent coating with a higher dry residue than teak and tung oils. The material has a mild solvent odor. The coating has a transparent base option is also possible tinting !

How to apply:

Danish oil is applied in 2-3 layers with an interval of at least 12 hours, complete drying in 24 hours.
Application method: roller, brush or spray.
The oil is ready for use; if necessary, it can be diluted with an oil solvent or turpentine.
The oil is in the form of a liquid and is sold in the following standard containers: 1 liter. and 5 l.
Consumption: 1 l per 10-12 sq.m. / 1 layer

Wooden house, thanks unique properties wood is an ideal home for humans. Optimal humidity level interior spaces supported due to hygroscopicity and vapor permeability natural material, which continues to “breathe” within the walls of the log house. A living structure needs protection from adverse environmental influences.

Causes of destruction of wooden structures

Natural, man-made and anthropogenic factors, which can affect the integrity and health of the log walls:

• Ultraviolet radiation destroys lignin, which is the reinforcing framework of wood. When exposed to direct sunlight, outside surfaces darken, become porous, easily absorb moisture and quickly release it. As a result, the logs age prematurely and crack.
• Precipitation and high humidity air lead to swelling and then shrinkage wooden structures. Damp wood is a favorable environment for the proliferation of fungal microorganisms and mold outbreaks. A rotting corner of a log house can cause the destruction of a house.
• Insect pests and rodents, which can settle in the walls of a log house, damage the integrity of the tree.
• Exposure to concentrated acid-base solutions affects chemical composition wood 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 period– 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

At the construction stage they use constructive methods of timber protection from exposure to moisture, solar radiation, biological damage and fire. Activities are in isolation wooden blanks from the ground, constructing well-ventilated canopies at a sufficient distance from flammable materials and open sources of fire. Installation work can last several months, so it is important to prevent deformation and premature destruction of the building material.

Along with constructive methods for wood processing, they use 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, after all, the logs are covered with dark spots of lesions, you can get rid of them using bleaching agents that contain chlorine or active oxygen.

Traditional chlorine-containing bleaches negatively affect wood, destroying its structure, so it is better to use advanced technologies that meet global environmental standards. A drug "SENEZH NEO" based on active oxygen does not emit harmful substances and is suitable for processing wooden houses outside and inside.

Protective means for processing logs

Reliable and safe processing of a wooden house depends on what compounds it will be used with. On modern market exists a large number of funds from various manufacturers, which promise one hundred percent protection against all kinds of impacts on wood. The most popular and proven include:

• "SENEZH"– toning and preservative antiseptics water-based and acrylate-based, fire-bioprotective materials and bleaching agents. Russian production;
• "NEOMID"– antiseptics for interior and exterior work, repellents for insects and microorganisms, fire-retardant emulsions of efficiency groups 1 and 2, fire-retardant paint, wood-protective oil for baths and saunas. Manufacturer – Russia;
• "Belinka"– protective primer, colorless antiseptic, permanent impregnation, water-based glaze for lightening, paint with an ultraviolet filter. Slovenia;
• "Tikkurila"– colorless oils and water-based antiseptics, glazing materials, pigment paints. Protection from moisture, mold, rot and solar radiation. Finland;
• "Rogneda"– safe fire and bioprotective compounds, bleaches and protective and decorative coatings. Active antiseptics destroy emerging lesions and provide protection from 15 to 50 years. Russia.

• products are applied to cleaned and degreased surface logs;
• initially treat the affected areas;
• permissible temperature for organic compounds is above +50C;
• minimum temperature for using water-based products +100C;
• maximum air humidity – 80%;
• It is better to carry out external treatment of walls in the shade of the house and move behind it while working;
• Fire-retardant impregnations and coatings are applied after treating the wall with an antiseptic.

External treatment of the house with protective compounds

Colorless water-soluble antiseptics are used as a bioprotective primer deep penetration. For exterior work, it is allowed to treat walls with organic-based compounds (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 coated with a protective composition, paying special attention to Special attention end cuts. The lower part of the walls is impregnated with a special antiseptic from groundwater, seasonal flooding, microorganisms and rodents (for example – “ SENEZH”).

Fire protection is then applied to the walls. For these purposes there are fire retardant coatings and impregnation. 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, use means of the 1st group of fire protection efficiency with control tinting of the surface (for example - NEOMID 020).

The final finishing is carried out with coating or glazing antiseptics, which emphasize the structure and color of the surface of the log. To hide the lost one original appearance surface, facade can be painted with acrylate or oil paint. External coatings should be selected with UV protection (for example TIKKURILA WALTTI).

Internal protection of wooden walls and ceilings

TO internal work have increased safety requirements. To treat the inside of a log house, only water-based antiseptics are used. They are odorless, do not emit toxic substances, are breathable and moisture resistant. If there are signs on the walls inside the room dark spots, before applying the antiseptic, they should be treated with bleach based on active oxygen.

After the first layer of treatment has dried, you can apply it to the walls. fire retardant composition. "Senezh Ognebio" complex impregnation of the 1st group of effectiveness against fire, protection against mold, blue stains and insects. It does not change the color of the wood and is suitable for the interior.

Decorative finishing internal surfaces wood is treated with glaze coatings or acrylate-based paints that are resistant to mechanical damage, which for a long time do not lose their color and shine.

Wall treatment beeswax will allow you to fully preserve the environmental advantages of a wooden frame, although it will not provide long-term protection.

When choosing products for treating a wooden house, you must take into account the purpose and conditions of use that are indicated in the instructions, use only certified preparations for famous manufacturers. Timely protection will allow you to not worry about the condition of the wood for many years.
