The most durable wood impregnation. What is the best impregnation for wood, its main types. Whitening antiseptics

The service life of a wooden house depends on the correctness and regularity of the treatment of the outer surface of the walls with protective impregnations for wood from moisture and decay for outdoor use. At the same time, the use of a quality substance is no less important than compliance with the processing technology. In this article we will talk about the effect of protective substances on wood, the most important parameters of these substances and how to choose the best wood impregnation for outdoor use.

Why it is necessary to treat the house with impregnations from the outside

Wood, especially processed mechanically, is very vulnerable to ultraviolet light, various bacteria and fungi that destroy it. Under the influence of ultraviolet light, the wood changes color and loses the strength of the outer layers. In addition, under the influence of ultraviolet light, wood becomes more vulnerable to bacteria and fungi. Therefore, the correct impregnation protects the wood from both bacteria and fungi, as well as from ultraviolet radiation. Where do bacteria and fungi come from? Wood absorbs moisture from the air of the street or room, and also gets it from the rain. Then the sun heats the surface of the wood and begins the process of evaporation of moisture, called shrinkage, during which the log or timber shrinks in size. Therefore, a good protective substance should not interfere with the absorption and release of water vapor, because if the vapor does not come out, it accumulates in the wood, creating moisture that is ideal for bacteria and fungi, and if it is not absorbed, then the wood dries up, loses its strength and cracks appear between the crowns.

Requirements for impregnation from moisture and decay

The requirements for impregnations for outdoor work from moisture and decay differ from the requirements for protective substances (antiseptics) that are used inside the room, because the main factors affecting the wood differ. More details about the use of protective substances used for internal and external work are written in the article. Here is a list of the basic requirements for exterior materials:

do not interfere with the breathing of the tree;
effectively protect against bacteria and fungi even at very high humidity;
deeply penetrate wood;
do not wash out with water;
do not collapse under the influence of ultraviolet radiation;
increase the fire resistance of wood.
do not change the color and texture of the wood.

A good protective agent does not create a film on the wood surface that blocks or impairs the absorption and release of water vapor; therefore, the use of materials based on light or heavy organic solvents is undesirable. After all, they create a film on the surface of the wood, which completely or partially blocks the absorption or release of water vapor, which increases the humidity. Protection against bacteria and fungi is based on blocking their reproduction, because it is impossible to prevent the ingress of spores from the air, as well as completely eliminate the spores inside the wood. Therefore, to protect wood from fungi and mold, the most effective materials are based on natural preservatives - table salt, copper and iron sulfate and other similar substances.

No less important is the ability of the impregnation to penetrate into the wood, because the deeper the reagent penetrates, the better the log or timber will be protected. Because for effective reproduction of any microorganisms that destroy wood, two factors are required - sufficient moisture and oxygen access. The deeper the impregnation penetrates, the less oxygen will enter the deep layers of the wood, which means that fungi and bacteria will develop more slowly.

Rains not only wash over the outer surface of a log or bar, but also wash out any non-wood substances from them. Therefore, a good impregnation should not only penetrate deeply into the wood, but also bind with it, due to which it will be washed out not in a year, but in 3-5 years. An important factor affecting the life of the house is the resistance of wood to fire. Due to the treatment with appropriate substances, it is very difficult to set fire to a wooden house, which significantly improves fire safety. The effectiveness of such a treatment depends on the properties of the pyrophobic substance, therefore it is necessary to choose the most effective one. The last factor that influences the choice of protective materials is their effect on the color of the wood.

Is the use of multifunctional protective equipment justified?

Many companies offer multifunctional reagents that prevent the appearance of mold, rot or fungi, protect wood from insects and ultraviolet radiation, and increase the resistance of the house to fire. The advantage of such substances is obvious - they are much cheaper than materials that protect against specific threats. However, such funds also have a serious drawback - they are several times less effective, therefore, the treatment at home will have to be carried out every year. If we are talking about a small shed or bathhouse, then this is not scary, but every year it is very difficult and costly to process a solid two-story house. After all, it is necessary not only to apply protective agents, but first remove the old paintwork, then treat with reagents, sand and varnish or paint. This work will have to be done from the scaffolding or ladder, moving it along all the walls. Therefore, treatment with substances that will last 3–7 years will be easier, and even cheaper when hiring specialists than the annual use of universal means.

Manufacturers of the best impregnations for external treatment of wooden houses

Here is a list of firms whose products give the best results:

Senezh;
Neomid;
Antiseptic;
Belinkа;
Pinotex;
Tikkurila.

When choosing antiseptics for external treatment of a house from a bar, it is necessary to take into account several points, the main of which is the cost of the material. After all, the more expensive the material, the more likely it is to meet a fake. For this reason, the impregnations produced by the Russian companies Senezh, Neomid and Antiseptic are out of competition. Due to the low price, counterfeiting these products is unprofitable, and the effectiveness of original impregnations is not inferior to the best foreign samples. In addition, both Russian and foreign companies offer a large selection of antiseptics and insecticides, so you can always choose a remedy, both for preventive treatment and for affected wood. However, foreign products also have significant advantages.

Impregnations from Belinka, Pinotex and Tikkuril have a higher resistance to washout. Therefore, it is advisable to use Russian products if rot, mold or fungi have already appeared on the wood.

Here is a list of the most effective preparations for the exterior treatment of wooden houses:

Belinka Base;
CMP antiseptic;
Tikkurila Valtti Expert Akva;
Pinotex Classic;
Neomid Base Eco;
Senezh Ecobio.

It can be used on wooden surfaces previously treated with linseed oil or other wood-staining agents.
Provides long-term protection of wood from weathering. A specially selected system of alkyd resins with different viscosities, as well as the use in the composition of natural oils, provide the formation of a high-strength breathable protective coating, which at the same time has high flexibility and elasticity. The presence of natural waxes in the composition makes it possible to achieve increased resistance of the coating to the effects of atmospheric precipitation.
Protects wood from biodegradation. The newest environmentally friendly fungicides, included in the composition, protect wood from mold, putrefactive and wood-coloring fungi.
Protects against UV-A and UV-B solar radiation. The system of light stabilizers of this composition includes unique organic UV - absorbers and UV - absorbing nanopigments of a new generation, which makes it possible to achieve high resistance of the final coating to fading.
The coating has high aesthetic properties. Leaving the natural wood structure visible, the composition forms a silky-glossy varnish coating, which, thanks to the use of special transparent pigments, has a deep, rich, noble color. All Aquatex Extra® colors can be mixed with each other to create your own colors and shades.
Ease of application. The composition has high painting properties, does not smudge, perfectly wets the wood surface.
Convenience of packaging. It is sold packed in original "Eurobeds", which excludes the possibility of counterfeiting, as well as violation of the tightness of the container during transportation.

Decree of the Government of the Russian Federation No. 55 of January 19, 1998 established a list of goods that cannot be returned and exchanged:
cement, putty, plaster, primer, glue, paints and varnishes, wallpaper, wall and floor tiles, bricks, SKTs blocks, wooden beams and boards, putty and grouting and sealing materials, plastic, plywood and wood panels, gypsum plasterboards and other partition materials , sound-, noise-, heat-insulating materials, siding and facing products, linoleum, carpets, parquet, laminate, roofing materials (slate, tiles, roofing material, weirs, gutters), window products (slopes, frames, glass, handles, locking mechanisms), door products, assembly and fastening mechanisms and parts (channels, corners, I-beams, etc.), hardware, decorative items (balusters, palustra, stucco molding), etc.

Building and finishing materials, furniture made of different types of wood are appreciated at any time. Wood structures retain heat well, have natural beauty and environmental friendliness, and provide protection from noise. But many of the advantages of wood are downplayed by a big drawback - weak resistance to the negative influences of the environment. The tree is affected by insects, moisture, fire and other external factors.

To protect wooden products from various types of destruction, special protective compounds are used. Each protective device is designed with the site of use and purpose in mind. The structure of the material acquires properties that can extend the service life many times over. Depending on the composition of the product, the surface of the material either acquires a protective film, or a complete impregnation of the wood structure occurs. The article will consider: the best impregnation for wood in 2019-2020; types of protective equipment; appointment; advantages and disadvantages.

Types of protective equipment

By appointment, protective equipment for wooden products are divided into: water-repellent; fire retardant; universal; antiseptic; frost-resistant; complex; for indoor use; decorative; for external use. Depending on the base, the means protect wooden products from: temperature fluctuations; from the fungus; insects; moisture; rot; sun rays; mold. Basics of funds are divided into: silicone; aquatic; oil; acrylic; bituminous; saline.

What are the best wood impregnations?

Each type of wood preservative has its own advantages and disadvantages. Acrylic products are used to protect: from mold; moisture; rot; fungus. Suitable for indoor and outdoor use. They are non-toxic, odorless, but cannot withstand low temperatures. The products preserve the wood structure and are inexpensive.

Flame retardants in the composition of the protective agent create anti-fire properties. Waxes and oils provide moisture protection. Antiseptic products protect wood from rot, mold, and fungus. Only for external coatings, agents with solvents and bitumen are used due to the presence of harmful biocides and a strong odor.

Water-based products are suitable for indoor and outdoor use. They are odorless and dry quickly. Not suitable for old material. Salt products protect well against fungi, mold and high temperatures. The disadvantage is fragility.

Oil concentrate products are ideal for moisture protection. They penetrate deeply into the structure of the material. The disadvantages are fragility and flammability. The coverage needs to be updated periodically. Bituminous agents protect against insects, fungi and mold. But they have disadvantages - toxicity and flammability.

Protective agents with silicone do not only have anti-fire properties. But they provide excellent protection: from moisture; sun rays; insects; mold; fungus. Silicone products provide good air exchange.

The best wood impregnations for outdoor use are complex products. They combine fire-fighting, antiseptic and water-repellent qualities. They are often produced in concentrated form. When choosing protection, it is necessary to take into account the purpose and place of application of the product.

For the treatment of wooden structures indoors, you should choose safe and environmentally friendly products. These are water solutions without toxic odor and secretions, with natural oils and solvents. Quality products must have appropriate quality certificates. Pay attention to the manufacturer. You should not buy a product from an unknown company. It is important to consider the purpose and characteristics of the product.

Impregnation for wood, for work on the street is not the whim of the owner of a private log house or a house made of profiled timber. It protects it from moisture and wind, sunlight and woodworm bugs, rot, mold and even fire (flame retardant impregnation).

Important! In the variety of the range of paintwork materials, you can find paints that contain antiseptics and / or fire retardants, as well as substances that protect wood from moisture. They are not cheap. Take a closer look at them. If you are faced with the task of not only protecting a wooden house, but also changing its appearance, such paints will be a good purchase.

Varieties of impregnations

If it is decided to use wood for construction and decoration, it is imperative to protect it from external aggressive factors - moisture (snow, rain), because precipitation over time soaks the tree, causing it to deform and dry out. Without protection, the tree can rot, mold and fungus settle in it, which greatly reduces the service life and attractiveness.

The lower part of the log house from moisture, the fungus will protect the foundation, the basement - their installation does not allow the tree to come into contact with the ground. Installing a sufficient number of vents and ducts will reduce the risk of moisture build-up. The upper part of the log house can be protected from the listed factors only by using impregnations.

There are several types of external wood preservatives. They can be divided into several large groups:

penetrating (for interior work);
film (for outdoor);
antiseptics;
flame retardants (prevent easy ignition);
complex impregnations with both antiseptic and fire retardant properties.

Another division - by the main substance:

Aquatic. Versatile, suitable for both outdoor and indoor work, do not smell. They are powder, can be found commercially and in crystalline form. Diluted with water according to the instructions. They dry for a long time, they require preliminary processing of wood with sandpaper and wetting before application. Do not apply on dry wood.
Solvent-based. They penetrate deeply into the structure of wood, smell sharp, toxic until they dry completely. Ideal for external protection of wood from moisture, mold, insects that have penetrated the upper layers. Apply with a brush only. Available in various colors.
In oil. Classic stains, which were constantly used before. They penetrate deeply into the wood, protecting it from moisture, prevent cracking. On such surfaces, dirt and dust do not linger, they are washed off by the first rain. Can be applied with a brush or spray.
Varnishes for outdoor use. A separate group of wood protection products. They not only protect well from various atmospheric phenomena, but also give a beautiful appearance.
Acrylic. Protect wood from blackening and blue discoloration, insects and mold. Acrylic compounds impregnate wood - treated and untreated. They have a high decorative value and are available in various colors. Suitable not only for outdoor but also for indoor work. Dry for several hours.
Wax or impregnation wax / oil. After using them, it is impossible to apply any other impregnation. Therefore, choosing this option, you need to think several times.

Thus, for outdoor work, penetrating compounds on a different basis are preferred. It is worth mentioning tinting impregnations. In addition to protecting against moisture, mold and mildew, they give the wood surface a beautiful color, emphasizing the texture of the wood.

In addition to heat-resistant impregnating compounds, there are various types.

Purposes of using impregnations for outdoor use

Most of the impregnations are intended to protect wood from damage and destruction, to improve decorative properties. The main types of impregnations and their purpose:

Anti-darkening. The reason for the darker color of the wood over time is the penetration of fungus. High-quality impregnation will prevent fungus and therefore exclude darkening of the material. Different products protect wood for different periods of time, which can vary from 3 months to several years. Usually, more expensive impregnations work for a long time, since they are practically not washed out from the base. Some tools simply mask the problem, others act in a targeted manner, destroying microorganisms. It is undesirable to use impregnation with chlorine - the compounds burn out and destroy the tree. Oxygen in solution works much better without negatively affecting the base and making the wood lighter.
Against moisture, decay. Water-repellent impregnations are suitable for almost any situation. The compounds penetrate into the wood, preventing it from deforming and rotting, cracking. After applying the product, moisture will not penetrate into the deep layers of the material, air exchange is optimized. Most products contain UV filters that prevent the material from fading, which only improves its performance. The impregnation layer will have to be renewed every 1 - 3 years or as indicated on the label.
Against combustion. Impregnations with bioprotection and two-in-one fire protection are no less popular. There are topcoats (varnishes, pastes that change color, but do not penetrate into the structure) or in the form of compounds (impregnations that optimize the texture of the wood).
For important, bearing bases. It is recommended to use such means to cover load-bearing walls and other important elements that need to be more reliably protected from damage by fungus, insects, groundwater and precipitation. These impregnations tend not to wash out for years, supplemented with powerful antiseptic and fungicidal properties. More expensive products do not change color, while cheaper products can make the wood look greenish.

There are decorative impregnations that are water-based and contain acrylates, prevent the tree from changing its tone, and protect it from UV rays. The colors of the impregnations are varied, which allows you to change the main color of the tree in accordance with the chosen style.

Selection rules

Compositions for wood protection can be unidirectional and complex. The former protect against one thing: from moisture (water-repellent) or from rot, mold, bugs (antiseptic), or prevent fire (fire retardant). The latter act in a complex manner in three directions: they prevent rotting, repel moisture, and prevent the tree from flaring up in case of accidental contact with a fire source.

Rules for the selection of impregnations:

Decide what you need to protect the tree from. Complex impregnations are more expensive, but they save time and physical strength. Unidirectional formulations can be applied in turn, but you will have to spend three times more time and effort on this. Plus you need to remember that usually one layer is not enough.
Think about how important the look of the tree (house) is to you. You may need compositions that can be tinted, or they are available in colors.
Estimate the scope of work in order to buy as much impregnation in the building market as you need, do not forget about a small stock. This is especially important if the composition is tinted.
Do not buy impregnations from the construction market. This is due not only to the possible lack of a certificate for the goods from sellers, but also to inappropriate storage conditions. Impregnations should not be stored at subzero or too high temperatures.
Having chosen a tool, read the instructions for it. It always states how long the wood will be protected. Look only at the first digit. Any formulations with a color scheme in direct sunlight will fade within 3 to 5 years. Therefore, it makes no sense to spend money on expensive products that promise color preservation for 10 years or more. This is nothing more than a marketing ploy and a price boost.
Do not forget to check with the seller how the impregnation is applied, perhaps the best solution would be to purchase an inexpensive spray gun. This will save a little on the composition, and will ensure an even application without drips.

Important! Always wear a respirator. Even the safest environmentally friendly impregnations contain benzene. Inhaling it is harmful even in microscopic quantities. Oil and alkyd compositions are especially harmful to humans.

Manufacturers

The impregnation market is diverse. The compositions are produced by both domestic and foreign manufacturers. To have an idea, you need to familiarize yourself with the most famous brands:

LuxDecor Plus. A quality product of the European level - water-soluble impregnation for wood LuxDecor Plus appeared on the Russian market as an affordable means to combat several aggressive weather factors at once. She is not afraid of wind, rain and snowfall, and it is these conditions that most often harm wood. The impregnation also protects against rodents and fungus for a period of at least 3 years after treatment. Acrylic impregnation can be applied both outside and inside the premises, due to the absence of alkyd resins and solvents, it is completely safe for the environment and people living in the house. Suitable for decorating children's toys and furniture, it is odorless and contains wax. Has a gel consistency, which greatly facilitates application, and also reduces processing time. Does not flow even when painting the ceiling and provides a matte silky layer (when applied in two layers) that can reliably protect the wooden surface from decay and mold for a specified operational period.

This combination guarantees the buyer a high-quality preservative composition for protecting wood for a period of more than 55 years at a price significantly lower than foreign counterparts. The new generation antiseptic contains polymer dispersions, pigments, waxes and special additives, which together make it possible to use it to protect terraces, foundations, gazebos and any wooden structures and products, even in the case of prolonged contact of the treated surface with water and soil. A preparation of European quality can be used as a primary coating before painting with varnishes and paints, or perform an enhanced protective function during self-processing of wood. Suitable for brush, roller or spray application.

Advice! Before buying, look at the website of the selected manufacturer, study the range of impregnations and their properties, pay attention to the cost. Then make an estimate, counting everything to the smallest detail. Only then go to the store for the material.

There are many recipes for homemade mixtures that protect wood from decay and eating by wood-boring beetles. The main proposed composition is bitumen mixed with kerosene. However, such protection is relevant only for buried wooden parts, for example, fence posts or lower rims of a log house. It is impossible to imagine a wooden house coated with such a hellish, in terms of appearance, mixture.

Wax-based wood impregnation not only does not spoil the appearance of wood and has good water-repellent properties, but also protects against annoying insects. Anyone can cope with its preparation:

Prepare the ingredients - wax and turpentine, you can add rosin. The ratio of wax / turpentine is 2/1, wax, turpentine, rosin is 100/50/25.
Heat the wax in a water bath, then remove from heat, add turpentine to it. Mix thoroughly until a smooth paste is obtained.
The second option is to heat the wax in a water bath, add rosin. After dissolving, grind thoroughly and add turpentine in a thin stream. Add lavender or peppermint oil for a pleasant scent.

Important! You can cover railings, platbands, carved elements and the entire outer surface of a log house with such a composition. Further painting can be done with oil paints.

Both types of homemade impregnations have the following positive qualities:

can be used not only for outdoor work, but also for indoor;
have a pleasant persistent smell;
have good resistance to mechanical damage;
consist of environmentally friendly materials;
well repel water, protect from rot, mold, insects;
improve the appearance of the tree, make its texture clear;
do not peel off in the sun;
dry quickly (no more than 7 hours).

Surface preparation for processing

Treat with penetrating impregnations on clean, dust-free surfaces. If the tree has previously been covered with varnishes, paints or other impregnations, the composition of which you do not know, you will have to completely clean the surface of them before applying the protective composition. Use a variety of hard brushes, scrapers and a hot air gun for this if the paint cannot be removed otherwise. Additionally sand the surface to make it smooth, then remove the dust.

Prepare the impregnation according to the instructions and apply it to the surface of the wood. Depending on the composition, each subsequent layer is applied either to a completely dry one, or even to a wet previous one. Impregnation without tinting can be painted after drying.

The protection of wood from fire and atmospheric agents must be carried out during the construction phase. It is quite difficult to process a finished house. It will not be possible to protect qualitatively all parts of a completely erected structure, which means that the risk of tree destruction from penetration of moisture and insects into unprotected places increases.

Impregnation for wood is capable of all these factors and even give it a more aesthetic appearance.

Why do you need to impregnate wood

Wood is in great demand due to strength, environmental friendliness, hygroscopicity, sound insulation and heat capacity... In addition, the beauty and ease of processing wood puts it much higher than other materials in the manufacture of furniture, construction, decoration of houses and industrial premises.

Untreated wood collapses under the influence of many factors, therefore, numerous impregnations and antiseptics were created that protect the material:

from fungi,
from mold,
from rot,
from insects,
from ultraviolet radiation,
from temperature extremes,
from atmospheric precipitation,
from various damages,
from the penetration and settling of dirt.

Types of impregnations depending on their basis

Any protective impregnation is intended for different purposes and place of use... In this regard, a special composition is being developed based on the main component. Due to the combination of additives, impregnations may or may not have an odor, differ in consistency and color, create a film on the surface of the wood, or completely penetrate the pores of the material to be treated.

Water based

Water-based impregnations are available completely ready-to-use. They are distinguished by the absence of an unpleasant odor, therefore they are suitable for both outdoor and indoor use.

Water-based means application of the product even to a damp surface or to salt coatings, the combination of which is ineffective with solvent-based fluids.

Application is done with a brush or spray gun, vacuum method by soaking. The product dries quickly and penetrates deeply into the wood, but has one limitation - it cannot be used to process old dry material... This leads to the swelling of the latter and the formation of cracks on it.

According to their intended purpose, the substances can have antiseptic, fire-fighting and decorative properties, and protect from getting wet. They have lower wear resistance compared to other products.

Acrylic based

Acrylic based impregnations used to protect and decorate wooden surfaces both outside and inside the premises. They are environmentally friendly for humans, odorless.

Such mixtures have strengthening and water-repellent properties, are able to perfectly protect against fungus, mold and decay. After applying the impregnation, the service life of the material increases.

The array is subject to processing at any stage of construction. The product is applied with a brush or spray bottle.

The disadvantages of acrylic impregnations include low temperature intolerance.

Salt-based

Salt impregnations are available as a powder or a ready-to-use solution. They most often used for processing truss systems in order to protect them from fungi, mold and pests. In addition, due to the settling of salt crystals, such agents effectively protect against fire.

Application with a brush is possible, but the greatest effect can be achieved only by soaking or processing in a vacuum chamber. For this reason, mixtures are rarely used in everyday life, but you can order such processing in production.

Oil based

Oil impregnations have high water-repellent properties. Them actively used to cover wooden structures and furniture, which is located on the street and is constantly exposed to atmospheric precipitation.

The disadvantages include the flammability of the mixture and the impossibility of applying other means on top of it.

Based on alkyd resins

Alkyd impregnations contain antiseptic additives, oil and wax. The mixtures perfectly emphasize the natural beauty of wood, protect it from mold, mildew and influence, both atmospheric and physical.

After application with a brush or roller, long drying time, which many attribute to a significant disadvantage of such a tool.

Bituminous based

Bituminous impregnation is a thick black mass. The mixture is based on gasoline and diesel fuel. Most often, the product is made independently and is intended exclusively for external work due to its high toxicity and pungent odor.

Any kind of wood can be processed, even dried wood. After application, a dense protective layer is formed, which prevents the development of harmful bacteria and fungi, the attack of insects.

The composition assumes protection from moisture, but high flammability.

Silicone

Silicone impregnation has all the positive characteristics of other types of funds: water-repellent, antiseptic, UV protection and biodegradation. At the same time, the mixture does not form a film, allowing the mass to breathe.

It is applied in any convenient way. Sold as concentrated or simple liquids.

Types of impregnation for the intended purpose

Impregnation for wood can have different characteristics according to the type of impact. In each case, the one that suits the most is selected.

Antiseptics

Antiseptic properties of impregnation are aimed at protecting wood from rotting and the formation of fungus and mold, from attacks of various insects. Their individual components exclude the influence of biological factors.

A good antiseptic is highly resistant. It penetrates deeply into the structure of the material, has no unpleasant odor and is completely harmless to people. For protection during storage and transport, surface spraying is performed. Soaking is recommended during installation.

Fire protection

Acid formulations are the most reliable in this matter. This provides additional strength of the material while maintaining hygroscopic characteristics.

Alkaline impregnations are used much less frequently. They violate the structure of the tree and are not at all suitable for the treatment of visible surfaces.

Saline solutions are considered the most ineffective. Over time, salt crystals appear on the surface and spoil the appearance of the product.

The fire protection layer on external surfaces is valid for 2 years. For internal work - 5 years. The principle of operation is that the substances that make up the impregnation melt under the influence of high temperatures and form a thin film that prevents the ingress of oxygen.

Frost resistance

Frost-resistant liquids are designed to preserve the properties of wood at a temperature of about -40 ° C... They have antiseptic and protective properties.

Water repellent effect

Due to the presence of wax and oils in the composition, an absolute protection of wood from moisture penetration... Since the massif is destroyed even by hydrogen in the air, almost all impregnations have this effect, but there are also special tools that are designed for surface treatment in baths and saunas, for external work.

Decorative properties

Decorative impregnation for wood, most often acrylic, is used in order to emphasize the natural texture of the array... For decorative purposes, choose funds with the desired shade, matte or glossy film that forms after drying.

Complex impregnations

Most of the impregnations has many properties at once, differs in a complex composition, available in the form of concentrates.

The most popular are antiseptic impregnations with water-repellent and fire-fighting properties.

Which impregnation is better

A wide range of products can make the choice in favor of any one difficult, so you need to immediately distinguish the desired effects from the composition. In addition, the correct application of fluids for the type of interior or exterior work is important.

For interior work

When choosing an impregnation for wood processing, which will or has already been installed indoors, first of all, they pay attention to the environmental friendliness and safety of the solution. Water-based products with natural solvents and oils meet these requirements.

Conventionally, all products in this line can be divided into 3 groups:

antiseptics, which are designed to protect against decay, the formation of mold and mildew, temperature extremes, changes in shape and color;
moisture-proof, with which the baths are treated to protect the array from constant exposure to high temperatures and moisture;
fire retardant, significantly or completely reducing the risk of fire.

For outdoor work

When processing wood that will be constantly on the street and exposed to exposure to various harmful and atmospheric factors, the use of more aggressive impregnations is recommended. At the same time, harm to health and environmental friendliness, due to the work on the street, fade into the background.

First of all, an antiseptic impregnation is used, which not only prevents various microorganisms from living and multiplying in the structure of the tree, destroying it, but also preserves its appearance, since the material turns black during the life of bacteria and fungi.

If the surface was previously given the desired shade, the impregnation should protect from ultraviolet radiation.

Important! The most caustic impregnations are bituminous. The mixtures are used to treat load-bearing structures. After their application, the tree is not afraid of moisture or attacks of microorganisms. Even rodents are not afraid of him.

Colour

If it is planned to preserve the natural shade of the wood, the mixture is selected colorless and has a number of protective characteristics. To give the array the desired shade more expensive species are used colored impregnation for wood. This should not be confused with simple painting and impregnation. In the first case, an opaque background of the color is formed, and in the second, transparency is preserved and the structure is visible.

It is impractical to engage in tinting. It is easier to choose the impregnation you like most in the store using the shade card.

Application is carried out in any convenient way in several stages, between which there is a pause for the time of complete drying of the previous layer.

Bituminous. In addition to the main component, you will need gasoline or diesel fuel.

Production requires an open flame, a large metal container and a long stirrer. Solid bitumen must first be melted, stirring constantly and controlling the presence of undissolved lumps. Then the container is set aside or the fire is extinguished under it and the mass is allowed to cool slightly. The solvent is gradually added and kneaded to the required consistency. When using gasoline, it must be borne in mind that it evaporates quickly.

Heating the bitumen mass should be carried out slowly in order to avoid foaming and overflowing over the edge of the container. The cooking process may take different times, depending on the volume of the mass.

The finished product is capable of hardening, so it must be consumed immediately, adding a solvent if necessary.

You can cook at home cheap antiseptic from water and copper sulfate... Like any saline solution, such a mixture is made by dissolving in water in a given ratio, which depends on the type of wood:

For the treatment of household structures or objects inside the house, a weak solution is sufficient, which contains up to 4% salts, no more than 400 g per 10 liters of water.
For outdoor furniture, a more concentrated mixture is recommended.
For the treatment of pillars or structures dug into the ground, the solution is prepared from 1-2 kg of vitriol per 10 liters of water. The coating is carried out more thoroughly and in several stages.
To control the application of a weak liquid, add a little potassium permanganate to it. The treated area will be immediately visible, and the toning will disappear over time. More concentrated solutions will take on a tint due to the color of the salts.

The whole process consists in adding vitriol to hot water and stirring until it is completely dissolved. After cooling, the solution can be applied with a brush or spray bottle. The ready-made mixture is stored for several days, if use immediately after preparation is impossible due to weather conditions or other individual reasons.

The production of water-based saline solutions is also carried out indoors. The main thing is to make sure that they do not fall on things or in hard-to-reach places and cracks.

The construction market is filled with all kinds of impregnations for solid wood or finished products from it. All of them differ in characteristics, action and service life, and can be cheap or reach a high price range.

When choosing, it is necessary to be guided solely by the need for their application and what effects should be realized after their application.

In addition, you should avoid purchasing goods from unknown manufacturers, especially when it comes to impregnations that will be used for interior work.
