Fire retardant protection for wood: which one is better to choose. Fire protection for wood - which one is better. The choice of fire protection

Fire protection of timber and structures made of them is absolutely necessary today in order to guarantee their safety and human safety. Fire protection of timber and structures made of them is one of the main types of fire protection works that many companies carry out today.

Fire retardant protection for wood

In building codes and regulations (SNiP), GOST, standard and other regulatory documents it is indicated that in order to increase the fire resistance, it is necessary to carry out fire protection of timber, because it helps to reduce the boundaries of the advance of fire on sawn timber. Fire protection agents form a foamy carbon layer. Such a layer can be called a heat-insulating screen, it increases the period of heating of timber to the decomposition temperature.

According to GOST 16363, fire retardants are divided into:

group I substances. They turn ordinary timber into hard-to-burn timber.
Group II substances. They transform ordinary timber into flame retardant
substances III group... These products do not guarantee protection against fire. wooden buildings.

Experts check the quality of the treatment against fire according to appearance when paints and coatings were used. The applied material should cover the treated surface evenly.

If surface impregnation was used, then the quality of processing by the master is assessed by the flammability of the chips. For this purpose, surfaces that are treated with a flame retardant, sharp knife remove shavings up to 1 mm thick. As a result of igniting the chips, there should be no combustion.

Fire retardant for wood

Rules for applying fire retardants:

do not cover wet timber with such compounds (moisture content up to 20%)
will not cover correctly fire retardants surfaces that have already been painted.

Processing price wood materials from fire is determined by which method to use. Masters use different impregnations, paints, sprinkles. For maximum protection of lumber, it is worth using a deep impregnation agent under pressure. However, this method can only be implemented in an enterprise. We can say that the most productive solution that even a novice craftsman can cope with are surface impregnations and varnishes, which make timber non-flammable.

Experts divide all protective drugs into: active and passive. Active drugs directly affect the combustion process (similar to a fire extinguisher), while passive drugs are used as prophylactic ones. Perhaps one of the main ones can be called constructive fire protection timber, which is laid even at the construction stage. In this case, the structures are faced with thermal insulation, plaster is applied to the surface using the gunning method, heat-reflecting screens are mounted, and transverse section nodes of the structure.

The most popular types of woodworking are:

fire protection of attic (roof) compartments and the roof itself
protection of parts on escape routes
fire protection of deck boards
scaffolding protection
fire protection for wooden pallets and temporary structures.

The most common fire protection products today are divided into:

impregnation against ignition. O protective impregnation of wood p is carried out by processing timber with a special fire retardant solution on water based... The advantage of this method is the low price of the solution itself, as well as the rather high efficiency of bio-protection (there is no mold and mildew). This kind of impregnation is characterized by a rather long period of operation. Among the disadvantages: the appearance of traces of salt and the inability to use after the previous application of varnishes or paints
fire retardant varnish treatment. This method is used for processing wood-based panels, chipboard, fiberboard, etc. Often this method is used for processing parquet boards... These funds are quite expensive. Possible varnish drips
fire protection by paints. In this case, no special skills are required. It is fashionable to use a brush or roller for work. The only drawback is the color of the paint. It is white and difficult to clean. At the same time, this paint is different high efficiency, it resists the action of open fire.

The best fire protection of wood

Consider the 5 most popular companies that produce paints and varnishes to protect wood from fire:

Senezh ("Senezh-preparations"). The company sells two fire-fighting agents: SENEZH OGNEBIO and OGNEBIO PROF. The second tool is almost twice as expensive as the first, but it also creates a higher protection

Neomid ("EXPERTECOLOGY-NEOCHIM"). These funds are presented in building stores over 10 years. NEOMID products have all the documents that are responsible for the high quality of drugs

Pirilax ("NORT"). The Izhevsk company NPO NORT produces six different fire retardant impregnations (Pirilax +). They are suitable for interior and exterior work. The assortment is wide enough, but the price is also higher than that of previous drugs

Woodmaster, Pyrex (Rogneda). NPP Rogneda is a large domestic manufacturer of paints and varnishes. The company produces three products: Woodmaster, Pirex and Ecohouse

Olympus (Descartes). This company has been producing protective and decorative preparations for wood and stone since 1992. The company manufactures products: Fire bio-protection group 1 and Fire-bio protection group 2.

When choosing a product, you need to look closely at the funds of popular companies, purchase in specialized stores or large building markets.

Wood processing by fire

Yakisugi, or "languishing cedar," is a Japanese technique for finishing timber with fire. This procedure makes it possible to show the structure of the raw material, and provide it with protection from fire, rot and beetles. The period of operation of the obtained material increases to 80 years. Pros of material processed in this way:

fire protection
rot protection
protection against bugs and microorganisms
ease of process
does not change the external pitch and shade over time
the period of operation is about 80 years.

Today, for this procedure, they use gas burner... To obtain the desired result, resinous timber is folded into a triangle, after which it is fired for 7-10 minutes. The duration of firing is directly related to the durability of raw materials and is determined by the type of timber, its moisture content, and thickness. Next, you need to extinguish the surface, clean with iron brushes from ash and rinse with water. After that, the wood is Japanese technology ready.

For firing, Japanese specialists use conifers because they have a lot of resin in them. The most valuable is cedar. As surprising as it sounds, burnt wood burns very badly. You can additionally impregnate the material with special oils, which will make the raw materials even stronger and more durable.

Due to the fact that the reserves of wood on our planet are limited, today the issue of increasing its durability and resistance to various influences is extremely relevant. And, of course, the worst enemy of wood is fire. It is worth noting that preparations for protecting wood from fire cannot fully protect sawn timber, however, they make it possible for timber to resist better and longer destructive action flame.

Any building material, along with its advantages, has certain disadvantages. For wood, the main disadvantages are its susceptibility to combustion (and quite intense) and damage by microorganisms, as well as by wood-boring insects. There are means for processing, which differ in their action "narrowly targeted", that is, they protect either from one or another "enemy".

Complex preparations are much more convenient, as evidenced by the reviews of those who have tested them in practice when processing wood. This article will help you understand how to choose the right lineups for this group.

Means of fire-biological protection - drugs that replace at once 2 compositions of different use: a fire retardant (against fire) and an antiseptic (against wood decay). Therefore their additional use for processing lumber is no longer required.

It is impossible to take into account everything - the specifics of use, the type of wood (its porosity), the conditions of use (air humidity, temperature), and the like. However, there are a number of rules that should be followed in any situation. And simply - to decide on the answers to some questions.

What structural element do you intend to process?

All fire-biological protection drugs are characterized by certain features.

Some are resistant to the "surprises" of the atmosphere, therefore, for external works – the best option.
Others are completely transparent and are ideal for subsequent varnishing.
In the composition of the third, dyes may be present. If the wood is covered with something (hydro or thermal insulation, cladding,), then this is not important; in other situations, colorless compositions should be chosen.

In what conditions will the lumber be used?

There are quite a few of them - inside or outside the building (for example, the front part), temperature and humidity, whether further cladding (coating, painting) of the wood is expected or not. Only having clearly defined the basic requirements for the drug, one can begin to search for the most suitable composition in terms of characteristics (properties).

What is the area to be processed?

Fire-biological protection drugs are sold in different packaging. If it is necessary to impregnate a total of 15 m², is it worth buying the composition in a 10 l canister? This also needs to be taken into account when choosing, if it is possible to take a product identical in its main characteristics, but in smaller quantities. It makes no sense to take in reserve, since fire protection is not a deficit, and its effectiveness gradually decreases during storage.

What else to consider when choosing fire protection

Validity

This is where the majority of buyers, trying to save money, are "caught". Savvy manufacturers (advertisers, sellers) are actively positioning their fire protection as a means of long-term wood preservation. There are even assurances like "I processed it once - forgot it for 15 years." All this is nothing more than marketing tricks with the aim of simultaneously increasing the price of fire protection and increasing sales.

Such funds are effective on average for 5 - 8 years., and regardless of the component composition. But only if all the rules for the exploitation of wood are observed. For example, high-quality waterproofing is provided in areas where moisture is excessive or there is a risk of direct contact with liquids (vapors). Or the structure has been sufficiently insulated when temperatures drop very low. If the conditions of storage (use) of wood are violated, no "chemistry" will help, even if the sellers claim otherwise.

Protection group

It makes no sense to consider everything, since the most "serious" is provided by the first group... Such drugs not only prevent the spread of the flame, but also significantly complicate the ignition process itself. Sometimes this is enough to prevent a fire, especially when time is measured in seconds. Therefore, when choosing fire-biological protection, you need to look not at the cost of the composition, but at its group. She is one of the most important criteria.

Manufacturer

Considering the demand for such compositions, many firms and "firms" are engaged in their manufacture, sometimes very dubious, and even semi-legal or underground. This is the segment of the market in which it is easy to run into a fake. When choosing fire protection, one should, firstly, focus on well-known brands (even despite more high cost drugs), and secondly, be sure to get acquainted with the certificate for the product.

The price of fire protection

Almost the main indicator that we are used to focusing on when choosing a product. And how much does it correspond to the final cost of wood processing? The fact is that the preparations differ in both concentration and packaging, that is, the capacity of the bottle (balloon, and so on). So you need to calculate how much this or that composition will be needed if it is diluted in the proportion recommended by the manufacturer. Only such a rational approach to the choice of bioprotection (subject to all other rules) will make it possible to reasonably save.

A brief overview of the most popular bio-fire protection means

All prices in Russian rubles, as applied to the Moscow region, are indicative.

"Senezh"

A fairly well-known Russian brand specializing in the production of various preparations for wood processing. In terms of fire-biological protection, two are of interest - "Senezh firebio" and "Senezh firebio prof." In many respects, they are similar, but in some indicators there is a difference.

First, the “prof” series is more expensive.

Secondly, it contains a dye, and "Senezh firebio" is completely colorless, that is, it is suitable for processing wood that will be varnished or transparent paint.

Price: "Senezh firebio" series - from 690 (10 kg), "Senezh firebio prof" - from 605 (5 kg).

"Pirilax"

Fire bio-protection of the Izhevsk NPO "North". The manufacturer offers 4 modifications of drugs. The convenience of choice is ensured by a variety of packaging - from 1 to 65 kg and a lower consumption of formulations in comparison with "Senezh" (about 1.5 times). When buying, you should carefully familiarize yourself with the characteristics, since a large assortment of products also determines an impressive range of parameters. For example, the protection period is from 2.5 to 7.5 (with external impregnation); conditions of use (for which structures, premises, and so on). If you focus on fire protection under the Pirilax brand, then there really is something to choose from.

Price - from 379 (1 kg) to 1716 (25 kg).

Fire-bioprotection NPO "Rogneda"

Another Russian brand of drugs. There are 3 modifications of formulations on the market - Pyrex, Woodmaster and Ecodom, each of which is produced in different series and packaging.

Prices: "Pyrex" - from 548 (0.8 kg) to 4 198 (12 kg); "Woodmaster" - from 309 (5 kg) to 456 (6 kg); Ecohouse - from 208 to 317 (5 kg).

"Neomid"

There are 4 preparations on sale, 3 of which are impregnations, and one (040 Professional) is used for staining in order to protect against fire and bioprotection. Packing - from 1 to 200 kg.

The price starts from 25 rubles / kg.

"Olympus"

Fire-retardant protection from JSC Descartes. Here the choice is small - 1 composition of the first and second groups. Standard packing in cans of 5, 10 or 20 liters. Increased consumption - within 525 (±%) ml / m². But given the low cost, in the end, fire protection will be inexpensive.

The composition of substances that impede the combustion of wood include fire retardants. They envelop the wood and significantly slow down the combustion process. In addition, antiseptics are added to the mixture that protect against mold and decay.

By the nature of the action, the funds are very different:

the composition melts. Under the influence of fire, a tree is formed protective film... It prevents oxygen from reaching the wood, thereby slowing down combustion;
the composition swells. As the temperature rises to promote combustion, the mixture begins to swell, blocking the path of the flame;
the composition decomposes. When the bio-fire protection decomposes, gases are released that do not support combustion.

Attention! If, in a fire, an untreated log house is destroyed in 15 - 20 minutes, then the spent one can last a day.

Wood processing is carried out:

step by step, first an antiseptic, then fire-biological protection;
simultaneously with two types of impregnation.

By consistency, protective substances are divided into:

impregnation. They are odorless, capable of developing and improving the structure of wood;
coatings (enamels, pastes, varnishes). They worsen the structure of the tree, smell bad. Used for trim elements.

According to the composition of the mixture there are:

water-soluble, more natural and persistent;
organically soluble, they must be diluted with toxic combustible compounds.

The right choice of protective compounds

Means for bioprotection are so important that you need to choose them not only on the advice of the seller, but also on the basis of your own knowledge.

What points should be considered when buying:

Does the seller have a certificate of conformity and the conclusion of the sanitary and epidemiological station.
Efficiency group.
The basis of the composition (saline or non-saline).
Consumption.
Absorption depth.

Composition and documents

Every wood processing product must have documents without which the sale is illegal. When buying, be sure to ask the seller to bring the certificate of conformity and the conclusion of the sanitary-epidemiological station. The certificate must contain all the information regarding the features of the application and the group to which the product belongs.

Another important characteristic is the composition of the impregnations. They may be:

saline. Easily washed out with water, lasts only 3 years. Suitable for indoor wood processing;
non-salt. They last 10-15 years, non-toxic, effective for external use.

Efficiency group

The most important distinction different compositions are considered to be the 1st or 2nd degree of protection.
GOST divides fire retardants into 2 groups:

Protects effectively throughout the entire fire.
They prevent fire, but do not last long.

Advice. The more layers, the better protection... The properties of 6 layers of the 2nd group are close to the 1st layer of the 1st group.

If the 2nd group is indicated on the product, the tree acquires the properties of hardly flammable. If 1st, then it becomes fireproof. V residential buildings only the 1st group can be used.

Fire retardant consumption

The peculiarity of protective compounds is that when buying, you need to pay attention not only to the price tag, but also to the expense. After all, a cheaper product can be spent more, and in the end it will cost more.

Attention! Cheap salt formulations are consumed in 2-3 rubles. faster than expensive non-salt mixtures.

For example, "Senezh", a salt mixture of the 1st group is spent about 600g / sq.m. if you process wood 6 times. Means "Neomid" are more expensive, but provide the same efficiency at a consumption of 250g / km.m.

Depth of absorption into wood

According to the depth of penetration, two types of compositions are distinguished:

superficial, penetrating to a depth of 6 mm;
deep penetration... They penetrate to a depth of 12 mm.

Advice. The impregnation with color scheme facilitates application, because you can see where you have already gone with a brush, and where not yet. But the color remains for a long time, therefore, it is better to use a colorless product on the facade and in any prominent places.

The more common is the 1st option, because it can be applied with a roller or brush. In addition, such an impregnation does not reduce the strength of the wood product.

In residential buildings, it is necessary to use fire protection equipment of the 1st degree of protection

Funds belonging to the second group are specialized. For their application, special equipment is required.

Explanation of designations

As a rule, the same letter code is indicated on packages with impregnation of any manufacturer:

"B" In the composition - boric acid;
"D" Forms a protective film under the influence of flame;
"M". In the composition - copper sulfate, which protects against mold;
"WITH". Contains baking soda to protect against fire;
"F" Indicates the presence of sodium fluoride - a poisonous substance that destroys the pest and fungus;
"NS". Toxic composition that destroys woodworm and bark beetle;
"HA" is a gas-releasing agent.

Professionals advise to thoroughly clean the surface of cobwebs, dust, old impregnation or paint before processing wood.

The protective composition is applied to treated, polished wood with a moisture level of no more than 30%.

It is advisable to carry out all work at a positive air temperature, otherwise the water frozen in the capillaries will reduce the processing efficiency.

Active participants in construction forums argue about the need for bio-fire protection. Some are absolutely sure of its effectiveness, and some argue that if the room is well ventilated, the composition will disappear in 1-2 years and suggest covering the tree with a mixture of copper sulfate and lime. One forum member spent interesting experiment, treat the newspaper with fire-biological protection and tried to kindle a fire with it. The newspaper did not light up.

Popular brands of impregnation

The market is filled with worthy funds from domestic and foreign manufacturers. They differ in group, purpose and cost.

The most common are:

"Senezh". Used for outdoor and internal works... The term of protection against fire is 5 years, against bugs and mold - 20 years.
"Olympus". Treatment with the composition of the 1st group is possible inside and outside the premises. The fire retardant lasts up to 7 years, protection against insects and fungi - 10 years. For the 2nd group, the period is shorter - fire protection - 5 years, biosecurity - 10 years.
Pirilax. The formula of the composition is distinguished by the presence of preservatives that protect the wood from cracking and aging. Available with two protection groups. The validity period directly depends on climatic zone... If on external walls rains rarely affect, the protection from the flame will remain for 5 years. Term for indoor spaces- 12 years.

Frame construction beats all records in popularity. Glued laminated timber and rounded logs are also actively used. Builders remind that it is possible to use wood for construction only after appropriate protective treatment... Fire retardant compositions, selected according to the specified criteria, will help ensure the safety of any building.

How to choose fire-retardant wood protection - video

The treatment of wooden buildings of any type involves the use of antiseptics. However, before starting such manipulations, you should choose the best variety so that the wood will last for as long as possible. It is worth taking advantage of the experience of professionals and paying attention to the fact that they are trying to use not too expensive means that are ready to demonstrate high efficiency. It is important to determine what functions a deep penetration antiseptic for wood should perform. This is because universal remedies are not as effective, so you need to use directional formulations.

Substances for protection against fungi

Fungal formations begin to appear in the wood that is used in a humid environment. The material soon gets covered in controversy. Experts advise in this case to use one of two means, among which one can highlight the PAF-LST brand antiseptic, as well as "Homeenpoisto-1". You can buy them on the market for relevant goods for an average of 110 rubles per liter. Do-it-yourself wood antiseptic can also be created. Such substances are highly effective, they consist of a mixture of engine oil processing with copper sulfate... In some cases, fumigation of the room with sulfur is used, but this approach cannot be called safe.

Biosecurity of wood in special conditions

If there is a need to protect wood from the effects of atmospheric precipitation or soil, then it is best to resort to an antiseptic of the Ultra brand, which has many positive reviews. The most famous is what has the name "Valtti Aquacolor".

This deep penetration impregnation creates a special surface on the surface. protective layer... It can be used when building a house based on glued laminated timber. The application of such a substance is carried out on a previously cleaned and dried surface. It is important to apply about three coats. The drying time of the previous one before applying the next is about 7 hours. As for complete drying, it will be achieved 12 hours after application. Before purchasing this impregnation, it is necessary to take into account that its consumption will be 1 liter per 10 square meters... You can buy such an antiseptic in containers, the volume of which varies from 0.5 to 50 liters. The cost starts from 70 rubles.

Antiseptic for wood of natural moisture

If you choose the best wood preservative, which has natural moisture, then you can use substances characterized by a non-washable structure. After its penetration into the lumber, the latter will change its original color to light greenish. According to reviews, the best remedy with a similar effect is what is produced under the brand name "Finesta". In the shops building materials such a product is presented in containers, the volume of which can vary from 10 to 200 liters. For 10 liters you will have to pay about 250 rubles.

Antiseptic for unrooted wood

The hardened wood is a round timber from which the bark has not been previously removed. It can be purchased directly from sawmills, and the cost of such material will be much less compared to a trimmed log. Keep this material recommended in a dry and well-ventilated area. However, not everyone can afford to have warehouses. For storage, you can apply a special-purpose antiseptic. If we consider the rating of reviews, then the Neomid 420 brand is the most affordable and economical. You will have to pay for it from 100 rubles and more.

Priming antiseptics

An external wood preservative can also be made on the basis of a primer. In this case, the surface after processing can be coated with paint or varnish. They are not particularly preferred by professionals for the reason that they do not have such a significant service life. Moreover, if the previously primed surface is left without topcoat for a period that exceeds 7 days, then the substance will be washed off by precipitation.

Among the primers, the most positive reviews can be found about Pinotex Base and Valtti Pohjust. Buyers point to evenness of application, quick drying and excellent adhesion to the surface. Paints and varnishes on such a primer do not flake off after 1-2 years, and you can choose a product from a wide range. The cost of priming antiseptics is 110 rubles and more.

Tinted bioprotective antiseptic

If you decide to choose antiseptics for deep penetration wood "Senezh", then you can prefer a tinted type of substance that allows you to achieve an even color. By choosing best line-up, it is necessary to pay attention to the presence of the skills and abilities of the master. After all, applying varnish, it will be quite difficult to achieve an even layer, and in the end you can get a “camouflage” of color. This effect can be avoided by applying a tinting antiseptic, which is covered with a transparent varnish on top.

Almost any antiseptic can be tinted, but the one that is produced under the brand name "Pinotex Classic" has shown itself better. Using the tinting method, it is possible to achieve one of 50 shades. You will have to pay for such coverage about 150 rubles per liter.

Bioprotective antiseptic with ultraviolet filter

Deep penetration can also excellently protect against ultraviolet rays, which can harm the material. Among other things, paint on walls without such protection will soon fade and lose its characteristics. Among the most common are "Neomid Bio Color". These compositions are also distinguished by the fact that they are allowed to be tinted in order to give the surface a shade. The walls will not be afraid not only of the sun, but also of microorganisms. Such formulations can be purchased for 170 rubles per liter, but additional bio-antiseptic application is no longer required.

Antiseptics for open areas

If you choose a deep penetration antiseptic for wood that is operated on outdoors, then a composition with appropriate qualities should be chosen. Thus, for open areas like terraces, you can use compounds that are resistant to washout and withstand temperature extremes. Most good decisions: "Pinotex Terrace" and "Pinotex Natural". You can buy them at a higher price, which starts at 350 rubles. However, you can count on superior quality and durability, which in this case come first.

Antiseptic for old wood

A deep penetration antiseptic for wood can also be designed for a material that has already been painted and / or has been used for a certain period of time. According to reviews, such substances are not as effective; only a protective film will be created on the surface. Experts advise to initially rid the base of old paint and only then proceed to processing.

Consumers who do not want to waste time and money purchase "Valtti Techno". The composition will be able to extend the life of the building, but treatment will need to be carried out every year. The cost of the train will be approximately equal to the above amounts, that is, 110 rubles per liter.

Bleaching wood

A deep penetration antiseptic for wood is often used in order to exclude a change in the natural color of the material. The application of such products should be done with a brush to a specific place. After 2 hours, the surface brightens, acquiring its original shade. If necessary, the procedure can be repeated about 3 times. If you decide to use the most effective remedy, it is recommended to purchase "Neomid 500", which costs about 170 rubles per liter on the building materials market.

If you decide to prepare antiseptics for a deep penetration tree with your own hands, then instead of the above, you can use traditional whiteness. However, you need to be prepared for a strong odor.

Sauna antiseptics

Baths and saunas also require treatment. But wood under such conditions is unnecessarily exposed to moisture and temperature. That is why the above compositions cannot be used here. It is not recommended to use substances that have a pungent odor. You can buy the "Senezh Sauna" product, which has a colorless structure and perfectly whitens the walls. Upon penetration, the substance creates a protective layer. And the composition can be purchased for 270 rubles.

End protection

Neomid, which belongs to the group "Antiseptics for deep penetration wood," is now widespread on the market among consumers. It is often used when it is necessary to protect the ends, which are the most accessible places for moisture. If you process the ends, then the entire building does not need to be processed. The areas for protection must be carefully sanded or tapped with a rubber hammer, then the master can apply a special sealant. Consumers who value a good price-quality ratio choose Senezh Tor, which starts at 290 rubles. Despite the significant cost, the consumption of the composition is quite small, it is 1 liter per 15 square meters.

Fire retardant treatment

If, in addition to biosecurity, you need to protect wood from fire, then you need to choose a composition with appropriate functions. Such substances can be divided into 2 groups, the first of which is distinguished by the most impressive resistance to fire. This product is applied to houses with stove heating, as well as private and commercial saunas, which is relevant in both cases.

Wood is one of the most popular construction and finishing materials... In a house built of wood, an excellent microclimate is formed with optimal humidity: it is warm in such a building in winter and cool in summer. This material has a small drawback - without the necessary protection, it will become covered with fungus and mold, which will make it unsuitable for performing its functions.

Every specialist in the construction industry will tell you that to protect wooden structures, you need to use special antiseptics, which include special substances that protect the tree from fungus and mold. To see for yourself, you can read reviews on the Internet about how to protect a wooden surface.

Types of antiseptics

Before choosing one or another material for protection wooden surface, you need to find out what types of these products are found on the market. In general, an antiseptic is a water-repellent composition that does not allow microorganisms that feed on wood to take hold in the environment of this building material.

There are three main groups of this material:

Water-soluble compounds - used for preventive protection of buildings that do not have direct contact with high humidity;
Solvent formulations - universal material protecting the tree both indoors and outdoors. After it dries, a dense film forms, which reliably protects the building from moisture;
Combined compositions - are able to protect not only from fungus and mold, but also, for example, from fire, that is, they include the properties of fire retardants.

Modern technologies for the production of such impregnations do not use harmful chemical substances, therefore, such material will not emit a strong odor. This liquid is colorless so as not to hide the natural structure of the wood. Not having much experience in repair work, you can easily treat wooden walls, floors or ceilings with your own hands with an antiseptic.

Senezh products

The Russian company Senezh has been specializing in the production of impregnations that protect wooden buildings from a variety of harmful effects in any climatic environment. Their materials are among the best on the domestic market.

Why choose Senezh products:

products from this manufacturer not only protect the material from fungus, mold, fires, etc., but also, after drying, emphasize the natural structure of the wood, making it more attractive;
