Treat the outside of the house. The best way to treat a wooden house and an extension from the outside. Requirements for internal processing facilities

Buildings from natural wood have a huge number of advantages, but they also have significant shortcomings: tendency to rot and high sensitivity to microorganisms and fungi. If you do not regularly treat the wood with special protective compounds, the material will not be able to resist harmful insects, moisture, ultraviolet radiation, rot and mold.

What products are used to treat wooden buildings?

Treatment wooden houses and external extensions must be comprehensive, for this they use antiseptics, fire retardants, and means to protect against ultraviolet rays and varnish.

As an antiseptic, experts advise buying “Rogneda”, “Senezh”, “ Healthy Home", "Aquatex", "Tikurilla". In stores you can find products that simultaneously act as antiseptics and fire retardants. They protect the tree from rotting and fire.

To protect against ultraviolet rays, waxes and natural oils are used. They are applied in 2-3 layers, each with an interval of 12 hours.

What is primer used for?

After treatment with an antiseptic and fire retardant, you can start using the primer. For this purpose, only alkyd-acrylic compounds are suitable, penetrating into the pores of the wood and sealing them reliably.

The primer provides the wood with ideal adhesion. The product can be used to process wooden house and extensions not only outside, but also inside.

How to give a wooden building a flawless look?

To wooden building looked aesthetically pleasing and retained its flawless appearance for a long time, you need to treat the walls with special bleaching compounds. After all work is completed, the wood can be coated with several layers of wax. The log or beam takes on an attractive natural look; the building does not need to be painted.

If you decide to paint your house, you can combine two stages of treatment (painting and applying UV protection) by purchasing paint with UV filters. You don’t need to use a moisture protective agent if the house is being painted. waterproof paint or means for water based.

Products for treating wooden houses are designed to protect against mold, mildew, fire, harmful effects ultraviolet rays. Wax will give buildings an aesthetic appearance, and impregnations will prevent the building from shrinking, deformation and cracking.

Based on statistical data, country houses are mostly built from wood, despite the existing a large assortment others building materials. From logs in a short time you can build a beautiful and cozy home any sizes and shapes. 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. Special attention during processing it is necessary to pay attention to the ends; through their open longitudinal fibers, moisture is absorbed more easily and into 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 provide good grip paint and varnish materials with wood.
6. The final stage processing wooden log house is the transformation of its appearance. There are special paints, varnishes, etc. for this. 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. They are washed out with water over time and after a few years they are 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 frame 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.

Available for sale protective equipment for processing logs of domestic and foreign production. 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 are used to create them, identical modern equipment and technology.

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 narrow-purpose products aimed specifically at combating mold, rot or insects. But there are also complex formulations capable of providing 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). Non-washable antiseptics can be used to treat lower crowns, terraces, gazebos and other structures located on outdoors and subject to constant negative impact. Their composition is the most powerful and strong.

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

Processing example two-story cottage from profiled timber

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

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

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

Types of wood processing

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

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

For all of the listed types of objects there is a special type impregnation, which will help keep them in excellent quality during the use of residential premises for a very long period.

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

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

• aquatic;
• oil;
• chemical.

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

Basic processing rules

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

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

Everyone has different tastes, but most still agree on one thing - wooden house has its own unique aura. It is no coincidence that many people strive to have on their property, if not the main building, then at least a bathhouse. Thanks to its naturalness, wood attracts the eye like a magnet, from which it is difficult to tear yourself away. However, most of the advantages of such a structure can deteriorate due to improper processing of the building material.

Our task today is to explain to readers how to independently carry out such work on professional level so as not to disrupt the technology. We will also talk about how to treat a wooden house inside and outside.

Features of a wooden structure

Before continuing the article, it is necessary to understand what special characteristics of the material we can encounter and not violate them:

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

To 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 becomes easily dirty. Moreover, even with short-term exposure sunlight Without protective treatment, the log house darkens. With longer insolation, the wood acquires an unattractive gray tint, making the house seem dilapidated.
• Exposure to moisture.
  Without waterproofing, wood quickly absorbs water and swells. In dry weather, it gives it away, decreasing in volume. Such vibrations cause stress 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 promotes the development of mold, blue, and rot fungi. The first two types only spoil appearance wood surfaces. Putrefactive fungi destroy the structure of the tree. Gray mold is also dangerous to health, as it can cause severe allergic diseases.
• Insect pests.
  The activity of wood-boring beetles greatly reduces the quality of wooden structures. The main damage to timber is caused by the larvae of these insects, which gnaw 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, untreated by special means, are susceptible to corrosion processes, as well as the formation of fungus and beetle larvae.

Products for protecting wood structures

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

Such funds are divided into three large groups:

• Antiseptic impregnations and primers. Protect the house from the destructive effects of moisture, mold, and insects.
• Fire retardants. Fire retardant compounds that increase the resistance of wooden structures to open fire.
• Combined means. Provide comprehensive fire protection for a wooden house.

As a rule, products based on organic solvents are used to treat external walls. They are more difficult to wash out than water-soluble impregnations, so they are more effective.

Wood is treated with antiseptics immediately after cutting to preserve the material during transportation and storage. This protection only lasts for a short time, so after construction, the wooden structures of the cottage are again coated with protective impregnations.

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

A set of measures for protective treatment of the house

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

Antiseptic treatment of critical structures

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

Protecting wood from fire

Wood can be treated with fire retardants at the lumber production stage. To do this, the latter are immersed in a solution of a fire protection agent. Fire prevention can also be carried out after the construction of a cottage, summer house, or bathhouse. In this case, fire retardant compounds are sprayed onto surfaces or applied using a roller or brush. Wooden surfaces are also treated with fire retardants inside. In this case, the period of protection against fire increases.

Combined fire and bioprotection

Most protective impregnations have a complex effect. They not only prevent fire 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 fire for the duration of the fire. For this purpose, surfaces are coated with a fire 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. Helps to avoid this problem preventive measures, which are accepted at the production stage, as well as during the construction of a log house. To do this, the ends are coated with moisture-proofing agents, which form a thin waterproofing film on their surface. It is permeable to air, effectively repels moisture, but does not disrupt 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 outside 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 constructing from laminated veneer lumber, Garden House uses external processing houses matte covering paints Tikkurila. They are acrylate coatings with oil that decorate the facade and create additional protection wood from harmful factors. These coloring agents adhere firmly to the surface and subsequently do not peel off. There is no need to repaint the cottage in a year or two, since when using Tikkurila paints cosmetic repairs façade can be forgotten for at least 7 years.

A wooden house properly treated on the outside will last for decades, maintaining attractive appearance, strength, quality of natural material.
