Treat railings on the street with fire protection or not. Proper fire protection of wooden structures. According to the chemical formula, it is divided into two categories

Let's start with the most "hot" question: how, among all the variety, to choose a high-quality, effective and durable bioprotective impregnation for primary wood processing? Now in stores you can find a lot of products that promise miraculous protection, and the range of prices for such formulations, to put it mildly, is bewildering. It is difficult to give a definite answer, but there are a number of things that you should pay attention to when choosing a protective agent:

  • Manufacturer. There are not many manufacturers specializing in wood protection in our country. Before making a purchase decision, do not be lazy, go to the manufacturer's website. Make sure that you plan to purchase a product from a company that has already established itself in this field and is engaged in the development of exactly PROFESSIONAL products for wood protection.
  • Composition service life. The maximum period that can be achieved with self-applied with a brush is 30-35 years when using enhanced bioprotective impregnation, such as, for example, and only indoors. For conventional bioprotective compositions, this service life is 5-6 years. Many manufacturers indicate on the packaging of such impregnations the service life of 30 years or more. Under this phrase, as a rule, follows a footnote, where it can be written, for example, that this period of protection is possible if applied by deep impregnation or soaking. Both of them are industrial methods, unattainable in domestic conditions. Another version of the so-called “marketing ploy” is when the manufacturer, under the promised period, for example, 30-40 years, writes in small print that such durability is achieved provided that the composition is not washed out of the wood. Unfortunately, the fulfillment of this condition is also impossible in principle. Don't be fooled by unthinkable terms, read the label carefully before buying a product!
  • Composition consumption. As a rule, the cheaper the impregnation, the greater the expense declared by the manufacturer. Therefore, when you see a seemingly inexpensive product on a store shelf, do not rush to choose it. Calculate how much impregnation will be required to treat the structure, subject to the manufacturer's recommendations for consumption. The average consumption rate should not exceed 200-250g/m². While on some products you can find figures of 500-600g / m², which is quite typical for FIRE-retardant materials, but in no way can be the norm for BIO-protective compounds. Let's assume that you have decided on the manufacturer. The next question that needs to be clarified is what should the ideal scheme of work look like, following which you will get the most durable result? So, step by step, professional wood protection should look like this:
End protection.
  • Due to the different rate of evaporation of moisture from the end and side surfaces of the log, the end saw cuts of wood are primarily susceptible to cracking and further development of biodamages in the cracks. That is why the processing of these areas is of great importance. To protect the ends of wood from cracking, a composition was specially developed. When wood is treated with this composition, a polymer vapor-permeable membrane is formed on the surface, which regulates the rate of moisture evaporation and allows the tree to “breathe”. "BIOTOR" can be used for absolutely any end cuts, both inside and outside the premises. The composition strengthens the wood and can be used even on already cracked ends in order to prevent further development of cracks.
Temporary processing of wood for the period of drying, transportation and storage.
  • It often happens that already infected sawn timber gets on sale, or biodefeats on wood develop during its storage (for example, before construction begins) under the influence of external factors. There is also a high probability of mold and fungus developing on the wood in the process of the so-called “shrinkage” of the structure. In the first case, buyers can only be advised to inspect the lumber as carefully as possible before buying. But to prevent biodamage of wood during its storage and shrinkage, you can use the composition. This antiseptic impregnation is designed specifically for temporary protection of wood for up to six months. Moreover, BIOSEPT-Trans is suitable for application on wood, humidity up to 80%. The composition is produced in the form of a concentrate, which makes it possible to obtain about 70-80 kg of the finished composition from a 10 kg canister. This amount is enough to process a medium-sized building. And after 6 months, absolutely any paint and varnish coatings can be applied to the wood treated with the BIOSEPT-Trans composition. Oddly enough, but it is this stage in the construction process that is most often skipped, and this inevitably leads to a decrease in the life of the wood.
Wood processing in difficult operating conditions (lower crowns of the house, floor logs, subfloors, cellars, etc.).
  • The first question that arises at the stage of assembling a wooden structure is how to process wood located in places of high humidity? And this problem has a solution - bioprotective impregnation WOODMASTER® BIOSEPT-Ultra This powerful antiseptic composition will provide reliable and long-term protection of wood, even in direct contact with wet soil (earth). When applied with a brush, indoors, this composition will protect wood from destruction for up to 35 years! It paints the surface in greenish-pistachio tones. An important condition that must be observed when applying the product is to prevent moisture from entering the treated surface during the first 7 days after treatment. This is necessary to fix the composition in the wood.
Wood processing under normal operating conditions.
  • Even those parts of the structure that are not directly exposed to moisture are recommended to be treated with bioprotective impregnation. First of all, this applies to ceilings, partitions and truss systems. As a rule, these structures are subsequently sheathed, and not only do we not see what happens to the wood under the sheathing, but we also do not have the opportunity to carry out bioprotective treatment after the fact. For such structures, the composition is suitable
Prevention of insect pests.
  • In the case when there is a high risk of wood contamination by insect pests (for example, a neighboring building is affected), it makes sense to use a product that provides not only effective biosecurity, but also protection against insects. Such a composition is, In addition to the antiseptic properties of the BIOSEPT composition, this product has insecticidal properties to prevent intruders from appearing in the wood. By the way, this is also one of the few solutions that allow you to get rid of the larvae of carpenter beetles already present in the wood. In this case, it is used by injection, introducing into the inlet and outlet holes of the larvae.

In order for structures made of logs (however, like other wood products) to serve for a long time, they are treated with biological protection agents at the production stage.

The main purpose of these chemical compositions:

  • prevent the development of blue, which can occur in conifers with high humidity;
  • protect the tree from the effects of woodworm insects;
  • prevent mold and fungus growth. But in addition to resisting biological factors, one should not forget that wood is a combustible material. Therefore, the fire protection of finished products is as important as impregnation with antiseptic agents.

Features of applying biologically active impregnation

There are four methods of antiseptic:

Brush application

The cheapest and easiest way that does not require special equipment or special knowledge. Despite the high labor intensity, it is successfully used for antiseptic treatment of logs and other large-sized lumber in small industries. The main disadvantage is the human factor and the need to apply impregnation in 2-3 layers.

2) Spraying

Compared with a brush, the use of sprayers greatly speeds up the antiseptic process. For processing, pneumatic sprayers or portable (knapsack) sprayers are used. But manual labor remains the same constant problem.

3) Machining

In large industries, stationary machines of the through-type type are used with the possibility of automatic processing of the log with an antiseptic.

The principle of operation of the device:

  • the rounded log is fed manually or by means of a drive;
  • from the tank, the pump pumps liquid, which sprays the workpiece through the nozzles and flows back into the tank;
  • the tank capacity is closed with a filter that prevents sawdust and other foreign substances from entering the antiseptic;
  • the system of chippers at the inlet minimizes the possibility of penetration of chips into the body, at the outlet it cuts off excess liquid.

4) Immersion in baths

The principle is simple: the capacity of the impregnating bath (concrete or metal) is filled with an antiseptic, where the lumber formed into a bag is immersed. In this case, the liquid level must exceed the level of the immersed material by at least 10 cm. To prevent the wood from floating up and being impregnated evenly, the logs are stacked with a mandatory gasket layer and pressed with a metal frame.

But for the application of this technology, it is necessary to have a lifting mechanism for lowering / raising a package of logs. And when using antiseptics in the form of a dry powder, it is necessary to install a special mixer in the bath to prepare the solution.

Of course, the deeper the antiseptic penetrates, the more reliable will be the protection against the harmful effects of various biological destroyers. The best indicators are characterized by products processed by immersion with the use of hard-to-wash antiseptics.

But the depth of impregnation depends not only on the technology of application, but also on the type of wood.

According to the degree of penetration of protective agents, GOST 20022.2-80 divides wood species into the following subgroups:

  • difficult to impregnate - spruce, fir, Siberian larch;
  • moderately impregnated - Siberian pine, cedar, European larch, oak;
  • easily impregnated - Scotch pine, beech.

As you can see, the wood from which the rounding is mainly produced (pine, larch) lends itself quite well to impregnation. But with spruce you have to work hard.

Classification of biosecurity agents

All means of bioprotection are divided into: flame retardants, antiseptics, universal preparations of combined effects.

By solubility, all protective agents are divided into:

  • oils;
  • water-based preparations;
  • diluted in petroleum products and light solvents.

Since all preparations that contain oils in the composition worsen the fire resistance of wood, water-soluble substances (sold in the form of powders or liquid concentrates) have received the greatest use for impregnating lumber.

Purpose and methods of fire protection of wood

For what?

Today, much attention is paid to ensuring the fire safety of load-bearing, enclosing and other building structures made of wood. Of course, not a single impregnation will preserve the structure in the event of a full-fledged fire. The rate of charring of coniferous wood due to the high content of resinous substances is high - 0.7-1 mm / minute. Therefore, at the advanced stage of combustion, surface impregnation will not be able to affect the rate of charring, but will only delay ignition for up to 4-5 minutes, which will make it possible to extinguish the fire.

According to statistics, 80% of fires are formed due to the so-called low-calorie fire sources (cigarette butts, burning matches, welding, electrical short circuit, etc.). From these accidents, fire retardant impregnation is provided, which will “muffle” the interaction of wood and sparks, and will make it possible to prevent a fire at the stage of occurrence.

The main methods of fire protection used in wooden housing construction:

  • constructive - lining with non-combustible materials;
  • chemical - the use of impregnating compounds, paints, enamels.

Flame retardants are used in the production of logs for fire protection - they practically do not change the color of natural wood and meet the requirements of fire safety standards.

Methods for applying fire protection do not differ from antiseptics, they are also applied with a brush / roller, spray or immersion in a bath.

Features of applying impregnating agents for fire protection

  • Flame retardants are applied to finished products that will not be subjected to further machining.
  • The moisture content of wood should not exceed 15%.
  • Processing is carried out at a temperature not lower than +5, and air humidity not more than 70%;
  • The composition should be applied in an even layer, without sagging and gaps.
  • Quality control is carried out using PiP-1 (a portable device designed by VNIIPO) or by assessing the ignition of chips from a simple match. To do this, chips up to 1 mm thick are removed in 4-5 different places per 1000 m 2 of the finished product. If the wood is well processed, the chips will not ignite when the match is ignited.

How to choose the right means of fire and bioprotection

When choosing preparations for impregnation, special attention should be paid to possible fumes and their effect on human health.

Main criteria:

  • the absence of organic solvents, salts of heavy metals (anion of chromic acid, cations of arsenic, copper, etc.) in chemicals;
  • durability - compositions for impregnation of internal structures should not be washed out with water, destroyed under the influence of ultraviolet radiation and remain operational for at least 5-7 years (for internal structures - at least 30 years);
  • stability - during operation, the product should not evaporate or decompose.

Providing a quality certificate, a sanitary and epidemiological conclusion, a package of documents from the manufacturer indicating the components of the mixture and recommendations on safety measures when working with the product and its disposal will help determine the purchase. The presence of only a sanitary-epidemiological conclusion is not a guarantee of safety. Many chemical components that we are allowed to use for wood processing according to the old GOSTs are recognized in many countries as harmful to human health.

It is best to trust a large manufacturing plant with a good reputation. So, among the imported manufacturers, the brands Tikkurila, Ici Paints, Caparol, Bochemie, Sadolin, Remmers, Belinka, Osmo are distinguished. In the domestic market, they are worthy of competition by the products of Senezh-Preparaty LLC, NPO NORT, CJSC Rogneda, CJSC Antiseptic.

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

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

  • composition melts. Under the influence of fire, a protective film forms on the tree. It does not allow oxygen to reach the wood, thereby slowing down combustion;
  • the composition swells. During the increase in the temperature that promotes combustion, the mixture begins to swell, blocking the path of the flame;
  • composition decomposes. When fire bioprotection decomposes, gases that do not support combustion are released.

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

Wood processing is carried out:

  • in stages, first antiseptic, then fire and bioprotection;
  • simultaneously with two types of impregnation.

By consistency, protective substances are divided into:

  • impregnation. They are odorless, able to show and improve wood structures;
  • coatings (enamels, pastes, varnishes). Deteriorate the structure of the tree, smell bad. Used for finishing elements.

The composition of the mixture is:

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

The right choice of protective compounds

Means for fire bioprotection are so important that they should be chosen not only on the advice of the seller, but also based on their own knowledge.

What points to consider when buying:

  1. Does the seller have a certificate of conformity and the conclusion of the sanitary and epidemiological station.
  2. efficiency group.
  3. The basis of the composition (salt or non-salt).
  4. Consumption.
  5. Depth of absorption.

Composition and documents

Each wood treatment product must have documents without which the sale is considered illegal. When buying, be sure to ask the seller to bring a certificate of conformity and the conclusion of the sanitary and 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, the validity period is only 3 years. Suitable for wood processing indoors;
  • non-salt. Keep 10-15 years, non-toxic, effective for external use.

Efficiency Group

The most important difference between the various compositions is the 1st or 2nd degree of protection.
GOST divides fire retardants into 2 groups:

  1. Effectively protect during the entire fire.
  2. Prevent fire, but do not last long.

Advice. The more layers, the better the protection. 6 layers of the 2nd group in terms of properties approach the 1st layer of the 1st group.

If the 2nd group is indicated on the product, the tree acquires the properties of fire resistance. If 1st, then it becomes fireproof. In residential buildings, only the 1st group is allowed.

Flame 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 consumption. After all, a cheaper tool can be spent more, and in the end it will cost more.

Attention! Cheap salt formulations are spent in 2-3 r. faster than expensive non-salt mixes.

For example, "Senezh", a salt mixture of group 1 is spent approximately 600g / sq.m. if you process wood 6 times. "Neomid" is more expensive, but provides a similar efficiency at a flow rate of 250g/km.m.

Depth of penetration into wood

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

  • superficial, penetrating to a depth of 6 mm;
  • deep penetration. Penetrate to a depth of 12 mm.

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

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

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

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

Explanation of designations

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

  • "B". In the composition - boric acid;
  • "D". Under the influence of a flame forms a protective film;
  • "M". In the composition - copper sulfate, which protects against mold;
  • "WITH". Contains soda that protects from fire;
  • "F". Indicates the presence of sodium fluoride - a toxic substance that destroys pests and fungi;
  • "X". Toxic composition that destroys woodworms and bark beetles;
  • "HA" means that releases gas.

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 not more than 30%.

It is advisable to carry out all work at 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 conducted an interesting experiment, treated a newspaper with fire protection and tried to kindle a fire with it. The newspaper did not catch fire.

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 can be called:

  1. "Senezh". It is used for external and internal works. The term of protection against fire is 5 years, against bugs and mold - 20 years.
  2. "Olympus". Treatment with the composition of the 1st group is possible inside and outside the premises. The flame retardant is valid for 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.
  3. Pirilax. The formula of the composition is distinguished by the presence of preservatives that protect the tree from cracking and aging. Available with two protection groups. The validity period depends on the climate zone. If the outer walls are rarely exposed to rain, then the flame protection will last for 5 years. The term for internal premises is 12 years.

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

How to choose fire bioprotection of wood - video

In wood construction, everything must be done on time. Unfortunately, many are convinced of the validity of this truth too late, noticing traces of the work of wood-boring bugs on the beams or looking at the coals of a burned-out house.

Wood is a delicate material. Despite the high strength, she is afraid of fire and dampness. Insects that feed on cellulose also pose a serious danger to it.

Without the use of special protection, not a single wooden house can withstand a fire, and its beautiful golden facade will become gray and dull in a couple of years.

How can wood be protected from aggressive factors? What are the best tools to buy?

How is fire protection applied correctly and is it not hazardous to health? We will answer all these questions in our article.

What is fire protection and how does it work?

Despite all the achievements of science, a tool has not yet been invented that 100% protects wood from fire and biological destruction. Any fire protection of wood only makes it difficult to ignite and slows down the development of microorganisms.

Since the main danger for a wooden building is fire, manufacturers focus on the effectiveness of fire retardants - substances that impede the process of wood combustion. It is their properties that we will consider first.

There are three main physical processes on which the action of fire protection is based:

  • melting of substances that make up flame retardants (salts of silicic, boric or phosphoric acids);
  • decomposition of substances that emit gases that do not support combustion (sulfur dioxide and ammonia);
  • swelling of the protective shell, preventing the contact of fire with the surface of the wood (organophosphorus compounds).

Most fire retardants, in addition to the flame retardant component, contain an antiseptic - a substance that prevents biodegradation of wood (mold, rot, blue, wood-boring beetles). A mixture of these two substances is called "fire bioprotection of wood."

Types of flame retardants

For a correct answer to the question of how to choose fire and bioprotection for wood, you need to know its properties and application features.

There are two groups of protective substances on the market:

  1. fire-retardant impregnation;
  2. Fire-retardant coatings (pastes, enamels, varnishes and coatings).

The main difference between them is the aesthetic qualities of the treated surface. Impregnations do not change the smell and texture of wood. Coatings, on the contrary, worsen the appearance of the treated surface and have an unpleasant odor. Therefore, they are used for processing load-bearing wooden structures hidden by decoration.

In addition, all fire bioprotective substances are divided into organically soluble and water-soluble. The first type of protection requires the use of flammable and toxic solvents, which significantly limits the scope of their use.

Water-soluble fire and bioprotection is safer and more versatile, so it is most often used in wooden housing construction.

According to the chemical formula, it is divided into two categories:

  1. Salt;
  2. Non-salt.

Non-salt fire and bioprotection for wood appeared quite a long time ago (80s of the last century). Despite its considerable age, it is actively used in practice today. The basis of such impregnations are salts of boric, carbonic or phosphoric acids.

The main advantage of salt protection is low cost. It has more disadvantages: a short period of validity (3 years), a low degree of protection, high consumption, the impossibility of staining and easy washing out with water. Therefore, salt compositions are mainly used for wood processing indoors.

Non-salt fire protection (based on organophosphates) is more beneficial. It does not spoil the appearance of wood, reliably binds to its fibers, has high rates of fire and biosecurity. Wood treated with such an impregnation can be painted and varnished. Non-salt treatment retains its properties for 10-15 years. It is non-toxic and safe for health.

Efficiency of fire protection

Here we come to the most important thing, for which, in fact, protective compounds are bought. Before taking your money to the cashier, pay attention to the protective effectiveness group indicated on the product label. It will not be difficult to figure it out, since there are only 2 groups that characterize the resistance of the impregnation to the action of fire.

If the 2nd protection group is indicated on the label of the composition, this means that after processing it, the wood becomes difficult to ignite. If you need to give the tree properties of fire resistance (higher resistance to an open flame), then buy drugs of the 1st group of fire retardant efficiency. For reference, we add that only such impregnations are allowed by fire regulations for processing wood in residential buildings.

It is also useful to know that by changing the number of layers of impregnation, you can easily vary the degree of its protection. For example, by making 6 “passes” with a weaker fire protection of group 2, we will get the fire resistance of a wooden surface at the level of group 1. And vice versa, having impregnated not two, but once the wood with a stronger protection, we get the 2nd group of fire resistance of the material. Be sure to take this fact into account in order for the treatment of wood with fire protection to give the desired effect.

Consumption, penetration depth and coloring power

An important economic indicator is the consumption of fire protection per 1 m2 processed surface. It depends on the purchase costs. Therefore, do not look only at the price tag of the product, but be sure to estimate the amount of impregnation from different manufacturers that you will have to purchase.

For example, cheaper salt compositions have a consumption rate 2-3 times higher than that of more expensive non-salt organosilicon impregnations. As a result, the apparent savings can be reduced to zero.

For comparison, we present the average consumption of different protective compositions. The consumption of "Senezh" - salt impregnation of the first generation is at least 600 g / m2 with a six-layer treatment. After that, the wood receives 1 fire resistance group. Non-salt and more expensive Neomid impregnation (Profiwood trademark) provides 1 protection group at a consumption of only 250 g/m2 (2.4 times less).

The next characteristic of fire-retardant compositions is the depth of absorption into the material. There are two categories of impregnations: surface (capillary) and deep penetration. The former penetrate into the wood fibers to a depth of no more than 6 mm, while the latter are able to enter the material deeper than 12 mm.

It is more profitable to buy surface impregnation, since it is easily applied with any painting tool (roller, brush or spray gun), does not create internal stresses in the wood and does not reduce its strength.

Deep penetrating protectants (mostly salt type) are rare on the retail market because they require special equipment and tooling to apply.

The appearance of wood is significantly affected by the coloring power of the impregnation. It allows you to easily control the quality and degree of processing, but worsens the aesthetic performance of the material. Therefore, it is better to use colorless impregnations on the facade sections of buildings and inside them.

Application features

Of the features of the use of impregnations, the following should be noted: fire and biological protection should be applied only to wooden structures that have undergone finishing machining (planing or grinding). The moisture content of wood should not exceed 30%.

In order to give impregnation the opportunity to protect the wood as much as possible, its surface should be thoroughly cleaned of oil stains, paint, dust and dirt before processing.

In most cases, the application of a fire-retardant composition must be carried out at positive air temperatures, since water frozen in the capillaries of wood prevents the penetration of the impregnation. Such work should not be carried out in rainy weather.

Well-known brands of fire bioprotection, approximate prices

Having studied our recommendations, you will be able to more confidently navigate the choice of impregnations, since the big name of the brand does not affect the existing technologies of fire bioprotection in any way. Only the quality of the constituent components matters here. For serious manufacturers, it fully complies with fire and environmental standards.

In addition to the already mentioned funds Senezh and Neomid, salt impregnations of the first generation Talezh, Olimp and Phenilax deserve attention. Their average cost is from 40 to 70 rubles per 1 kilogram.

Non-salt compositions of the second generation Pirilax and Neomid can be bought at a price of 120 to 320 rubles per 1 kilogram.

Comprehensive protection of logs with special antiseptics and flame retardants directly affects the long service life of country houses, summer cottages, cottages, elite residences. Qualitative treatment with fire bioprotection is carried out in order to get rid of pathogenic microorganisms, fungus, mold and bacteria, wood bug. And the special composition of flame retardants saves the life of buildings equipped with a firebox or stove, for example, a Russian bath.

Fire protection treatment, price - 50 rubles. per square meter (m2)

Where to order fire protection services?

Complex preparations for protection against fire and wood rot are represented by groups 1 and 2. You can choose the appropriate type of composition and order fire and bioprotection treatment at competitive prices without intermediaries and overpayments in our company. Experienced craftsmen will help to carry out the work correctly in full accordance with the technologies. So, for example, group 2 flame retardants may be suitable for roof truss systems. When arranging the protection of wet rooms, baths, saunas, compositions with enhanced properties are chosen.

A wide range of company services can be ordered by contact numbers, on the site with turnkey work in Moscow and the region, regions of Russia.

How is wood protected from fire and fungus?

Deep impregnation of lumber with fire retardants can be carried out in different ways. The easiest way to process fire bioprotection is with a paint brush and roller. Volumetric wooden structures are processed with a spray gun, spray gun using high pressure. Deep impregnation with flame retardants and antiseptics is achieved by immersing small parts in a container with a solution.

The cost of protecting logs and lumber depends on different criteria:

  1. Useful area of ​​the structure made of wood, logs;
  2. Types of antiseptics, fire retardants, complex compounds;
  3. The complexity of the work, types of roof construction, premises,
  4. Applications inside and outside.

Why choose quality formulations and deep processing?

Fire bioprotection is the main safety measure for private homes, commercial establishments, restaurants, bars, cafes, baths and saunas. Modern drugs have important qualities:

  • Fast and deep penetration into the wood texture;
  • The group of compositions for internal work is safe for health;
  • Gives fire-fighting properties and resistance to fungus damage for more than one year;
  • Protects the structure from fire and fungal attack for decades.

The use of preparations guarantees the protection and safety of wooden buildings, the chemical composition does not decompose over time.
