Wood is easily attacked by fungus and insects, and it ignites easily. Which fire protection is best for wood? Let's try to understand this issue.
Wood treatment products must contain substances that provide protection against damage by microorganisms and protect against fire. Wood is also exposed to changes in temperature, humidity, and mechanical stress, and therefore needs special protection.
Fire bioprotection can protect wood from biological pests and flames. If you treat wood with such means, you can reduce the risk of mold and fire.
Types of fire protection according to the method of their application:
- covering;
- impregnating (the most popular, since after the treatment you can clearly see the texture of the wood).
Choosing the right product
Senezh impregnations have proven themselves well. There are “Senezh Ognebio Prof” and “Senezh Ognebio” in the line. The product “Senezh Ognebio” is able to protect against fire, flame spread, blue staining, rot, mold, and insects that spoil wood.

This product belongs to the first (second) group. Substance consumption for the second group is 300g/sq.m. m, for the first – 600 g/sq. m.
We list the most popular brands of fire protection:
- "Senezh";
- "Good Master";
- "Neomid";
- "FOREST";
Product Features
There are different packaging of goods. You should not take it with a reserve, since this product can always be purchased in the store, and if it is stored for a long time, it loses some of its properties.
Fire protection can also be called impregnation. It can be produced in the form of paste, varnish, enamel, impregnation. If you intend to use putty or paste, then it has a smell; it is better to use it in places that will then be subjected to additional finishing, since it slightly spoils the appearance of the product. Impregnation has almost no ability to change the smell or texture of wood.
If you need to treat a wooden structure, then when choosing a product, give preference to water-soluble fire and bioprotection. It is often used because it is safer.
When choosing a product, it is worth considering whether there is permission from the SES for the use of this composition in residential premises, how much money is spent per 1 sq. m. m, fire protection efficiency group of the product, salt or non-salt type of product, the need for further surface treatment, application method.
Application methods:
- combined - the tree is immediately impregnated with protection;
- sequential - the wood is treated with fire retardants, then it is treated with antiseptic substances.
Otherwise, fire bioprotection can be called fire retardants. These are highly specialized products used for processing. The wood is treated before construction begins. It is necessary to wipe down scaffolding, scaffolding, various wooden elements, and also parts of the house frame.
About operating principles
Operating principle of fire bioprotection:
- refractory substances in combination with salts of silicon, phosphoric, boric acids, there are salt-free options;
- forming an impenetrable dense film;
- To reduce the access of oxygen to the object, fireproofing impregnation is capable of releasing non-flammable gases.
Fire protection is necessary when constructing residential and commercial buildings. Also, with its help, it is necessary to properly treat buildings that belong to the category with a high degree of fire occurrence.
This product is used to treat railway cars, ships, vessels, and barges. When performing restoration work, it is also necessary to use comprehensive protection.
The benefits of using fire protection
The advantage of using fire protection is its complex effect. If you treat wood externally with fire-resistant impregnation, you can effectively fight insects. This is due to the compounds that make up the product. Insects do not breed in wood if it is treated with antiseptic substances.
When choosing, you can give preference to products that belong to the first group of fire protection effectiveness. Consider the purpose of the material - whether it will be used for interior decoration, whether it needs to be used to process the supporting structure. To prevent the product from changing its color, choose colorless analogues.
The effectiveness and duration of drying are influenced by the method of application and the composition of the product. In some products it is permissible to use a larger amount of the product to provide improved fire protection.
Pay attention to how fire protection affects the material. It may swell on the surface, decompose into gaseous compounds, or the outer coating may melt.
Which products are better to choose?
The most common and affordable impregnations are those containing carbon, phosphorus, and boron salts. However, they are easily washed out with water; they need to be used more to process 1 square meter. m.
In addition, their service life is up to five years, and then it will be necessary to apply a new impregnation. At the same time, salt stains remain on the surface after treatment. If you use such an impregnation, then in the future it will not be possible to coat the wood with paints and varnishes.
It is better to choose salt-free impregnations. They are able to inhibit combustion processes. The bioprotection of materials treated with such means will last for a maximum of twenty years, fire retardant properties last up to fifteen years. The impregnations contain no toxic substances that could harm human health.
To ensure that the substance is well absorbed, the wood is dried. If there is an old paint coating, it should be cleaned before applying fire protection.
Impregnation is applied in several layers. The packaging indicates how much to use per 1 square meter. m. Apply one layer, then allow to dry, and the second layer is applied after twelve to twenty-four hours.
A necessary measure when using wooden building materials and structures. This is due to the fact that wood, more than other materials, is susceptible to the destructive effects of fire and biological pests. Professional fire-bioprotective wood treatment increases the durability of wood structures, preserves their appearance and protects them from fire, mold and destruction by insects.
Fire-bioprotection should be understood as the treatment of wooden structures and wood-based building materials with fire-bioprotective impregnations. High-quality and modern impregnation includes two active components - fire retardant and antiseptic. A fire retardant increases the fire resistance of structures and prevents wood from burning, and a wood antiseptic protects against the effects of biological pests. Let's take a closer look at the operating principle of these main components of the fire-retardant composition.
Fire retardants for wood - reliable protection against fire.
Fire retardants- substances that reduce and slow down the flammability of materials of organic origin, including wood. To understand how a fire retardant protects wood from fire, let’s remember the mechanism of wood combustion.
Under the influence of a flame, the moisture contained in the wood evaporates on a wood surface untreated with a fire retardant, and then flammable gases are released, which ignite upon contact with oxygen. In this regard, wood not only catches fire easily, but also supports combustion, increasing the area of the fire.
Fire retardants included in the fire-bioprotective impregnations of NPO Stroyzashchita work in two directions, protecting the wooden structure from the outside and from the inside. In the event of a fire, on the surface of wood treated with fire-bioprotective impregnation, non-toxic and non-flammable gases are released, cooling the wood from the inside, and a persistent film is formed from the charred components of the impregnation, blocking the flow of oxygen and preventing the maintenance of combustion.
Fire retardants have 1 or 2 groups of fire retardant efficiency, according to GOST R 53292-2009 “Fire retardant compositions and substances for wood and materials based on it. General requirements. Test methods". Group 2 flame retardants only prevent fire, while group 1 impregnations effectively protect wood at all stages of fire development.
When choosing a fire retardant, you should take into account both the efficiency group and the combustion characteristics of wood material. For example, coniferous wood burns several times faster than oak boards.
Under standard conditions, wooden structures not treated with a fire retardant composition collapse within 15-20 minutes. after the fire started. Structures impregnated with fire retardant retain their strength much longer, allowing people to evacuate from the scene of a fire and save property from fire.
Antiseptic for wood - protection against the harmful effects of microorganisms.
In addition to fire protection, wood should be protected from the destructive effects of mold, fungi and insects. For bioprotection, wood is treated with an antiseptic. Antiseptics- chemicals that prevent the destruction of the material under the influence of biological pests.
Microorganisms can destroy wood in the shortest possible time. Wood affected by fungi, and along with it structures made from it, lose mechanical strength and are not able to withstand the design load.
In a poorly ventilated area with high humidity, mold will form. Mold does not affect the mechanical properties of wood, but increases the rate of water absorption, creating favorable conditions for the development of fungi.
Insects pose a great danger. By gnawing passages in the wood, they destroy the material. Wood loses its mechanical properties and rots.
Treating wood with an antiseptic protects the material from destructive biological factors. When choosing an antiseptic, you should pay attention to the expiration date and composition of the product. Phenol, arsenic and chromium pose a threat to human health.
How to choose wood fire protection products
In Rus', houses, baths and sheds were traditionally built from wood. Today, timber and logs are popular materials for the construction of buildings. In order to protect the house from fire and fungus, fire bioprotection is used for wood. What is the best way to choose a high-quality fire retardant? Let's look at the characteristics of different formulations and reviews of their use.

Classification, characteristics and application features
Substances that impede the combustion of wood include fire retardants. They envelop the tree and significantly slow down the combustion process. In addition, antiseptics are added to the mixture to protect against mold and rot.
The nature of the action of the remedies differs greatly:
- the composition melts. When exposed to fire, a protective film is formed on the wood. It prevents oxygen from reaching the wood, thereby slowing down combustion;
- the composition swells. When the combustion temperature rises, the mixture begins to swell, blocking the path of the flame;
- the composition decomposes. When 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 antiseptic, then fire bioprotection;
- two types of impregnation at the same time.
Based on consistency, protective substances are divided into:
- impregnation. They are odorless, capable of revealing and improving the structure of wood;
- coatings (enamels, pastes, varnishes). They deteriorate the structure of the tree and smell bad. Used for finishing elements.
The composition of the mixture is:
- water-soluble, more natural and durable;
- organically soluble, they must be diluted with toxic flammable compounds.
The right choice of protective compounds
Fire protection products are so important that you need to choose them not only on the advice of the seller, but also based on your own knowledge.
Points to consider when purchasing:
- Does the seller have a certificate of conformity and a conclusion from the sanitary and epidemiological station?
- Efficiency group.
- The basis of the composition (salt or non-salt).
- Consumption.
- Absorption depth.
Treatment with fire protection agents is necessary for every wooden structure Composition and documents
Each wood processing product must have documents, without which the sale is considered illegal. When purchasing, be sure to ask the seller to bring a certificate of conformity and a conclusion from the sanitary-epidemiological station. The certificate must contain all information regarding the features of application and the group to which the product belongs.
Another important characteristic is the composition of the impregnation. They may be:
- saline. Easily washed out with water, the validity period is only 3 years. Suitable for indoor wood processing;
- non-salt. Lasts 10-15 years, non-toxic, effective for external use.

Efficiency group
The most important difference between different compositions is the 1st or 2nd degree of protection.
GOST divides fire retardants into 2 groups:
- Effectively protects throughout the fire.
- They prevent fire, but do not last long.
Advice. The more layers, the better the protection. 6 layers of the 2nd group have properties similar to the 1st layer of the 1st group.
If the 2nd group is indicated on the product, the wood acquires the properties of low flammability. If 1, then it becomes fireproof. In residential buildings, only group 1 is allowed.
Fire retardant consumption
The peculiarity of protective compounds is that when purchasing, you need to pay attention not only to the price tag, but also to the consumption. After all, a cheaper product may be more wasted, and in the end it will cost more.
Attention! Cheap salt formulations are consumed in 2-3 rubles. faster than expensive non-salt formulas.
For example, “Senezh”, a salt mixture of group 1, consumes approximately 600g/sq.m. if you process wood 6 times. Neomid is more expensive, but provides similar effectiveness at a consumption of 250g/km.m.
Absorption depth into wood
Based on 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 makes application easier, because you can see where you have already touched with a brush and where you have 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 visible places.
The more common option is option 1, because it can be applied by roller or brush. In addition, such impregnation does not reduce the strength of the wood product.
Means belonging to the second group are specialized. Special equipment is required to apply them.
Explanation of symbols
As a rule, on packaging with impregnation from any manufacturer the following letter code is indicated:
- "B". Contains boric acid;
- "D". Under the influence of flame it forms a protective film;
- "M". Contains copper sulfate, which protects against mold;
- "WITH". Contains baking soda that protects against fire;
- "F". Indicates the presence of sodium fluoride, a toxic substance that destroys pests and fungi;
- "X". Toxic composition that destroys wood borers and bark beetles;
- "HA" is a gas-releasing agent.

Professionals advise that before processing wood, thoroughly clean the surface of cobwebs, dust, old impregnation or paint.
The protective composition is applied to treated, sanded wood with a humidity level of no more than 30%.
It is advisable to carry out all work at positive air temperatures, otherwise water frozen in the capillaries will reduce the efficiency of processing.
Active participants in construction forums argue about the need for fire protection. Some are absolutely confident in its effectiveness, and some claim that if the room is well ventilated, the composition will disappear in 1-2 years and suggest covering the wood with a mixture of copper sulfate and lime. One forum member conducted an interesting experiment: he treated a newspaper with fire-bioprotection and tried to light a fire with it. The newspaper did not catch fire.
Popular brands of impregnation
The market is filled with worthy products from domestic and foreign manufacturers. They differ in group, purpose and cost.
The most common ones are:
- "Senezh". Used for external and internal work. The period of protection against fire is 5 years, against bugs and mold – 20 years.
- "Olympus". Treatment with the composition of the 1st group is possible indoors and outdoors. The fire 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, bioprotection - 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 the climate zone. If external walls are rarely exposed to rain, the fire protection will last for 5 years. The term for internal premises is 12 years.
Frame construction is breaking all records in popularity. Glued laminated timber and rounded logs are also actively used. Builders remind that wood can be used for construction only after appropriate protective treatment. Fire-retardant compounds selected according to the specified criteria will help ensure the safety of any building.

Conclusion
Wood, with all its advantages when used as a raw material for building materials, has a couple of serious disadvantages: it burns well and is just as easily attacked by insects and fungus. It is not surprising that owners of private houses are interested in finding compounds that improve the fire-retardant properties of wood. Let's try to help with the choice and present in one place recommendations and reviews on the use of certain compounds, and also answer the main question: how to choose the best fire protection for wood?
What is fire protection for wood?
There are about five hundred fires in Russia alone every day, millions of rubles are spent on eliminating the consequences. Just think: a wooden house burns down in just half an hour! And it’s good if the damage is measured only in money. Is it worth explaining why such great importance is attached to the processing of wood with special compounds? Usually, one product combines two useful qualities at once: protection against fire, as well as damage from microorganisms and insects - fire retardants and antiseptics in one bottle!
A small educational program. Fire retardants are substances that serve to prevent fire and subsequent combustion of wood and other combustible materials. Without going into the mechanism of their operation, we will stipulate that they can act in different ways: 1) when heated, they release carbon dioxide, thereby forming a non-flammable “cushion” covering a layer of wood; 2) when heated, form a fireproof swelling layer on the surface of the treated material; 3) at the processing stage, the fire-bioprotection solution clogs the pores of the top layer of wood, and, being a non-flammable component, literally reduces the percentage of combustible composition in the surface layer of the material. Antiseptics are substances that work against microbes, rot, mold, etc., and even against insects, for which wood is a tasty morsel. It so happened that to optimize the process and process the same critical structures, it is quite possible to use a 2 in 1 solution. This is what led to the wide popularity of fire-bioprotective compounds for wood.
7 simple rules you need to know when choosing
There are no miracles. The tree will catch fire sooner or later – it’s a matter of time. But sometimes the minutes count, on which someone’s life depends. The facts are that wooden buildings not treated with fire retardants burn faster than those treated.
1 or 2 group. In total, there are three groups, but only the first two are important for protection; in short, then: group 2 - retardation of flammability, group 1 - retardation of flammability and combustion. Those. The first group allows you to take fire protection seriously and provide the maximum possible protection.
The price is determined by consumption. The problem is that the packaging and concentrations of solutions can vary significantly, hence the difference in the consumption of the composition for treating 1 square meter. meters of surface. Don’t be lazy and estimate how much it will cost you to achieve the first or second group of protection when treated with one or another composition - don’t just compare the cost of the packages.
Specific properties. When choosing fire protection for wood processing, it is necessary to consider whether the structure will subsequently be exposed to moisture or changes in temperature conditions, whether it will be hidden from view by finishing materials, or whether it is planned to apply decorative layers over the treated parts. Because there are compositions that are resistant to external influences, some with dyes (to control work) and transparent ones - depend on the working conditions.
Everything is subject to time. The effectiveness of protection decreases over time. The usual period is up to 5-20 years, after which it is necessary to carry out treatment again. But the gap can be seriously shortened if the operating conditions of the structure are violated: exposure to moisture, freezing of structures, etc. Here it is necessary to make a small digression and explain the duration of the protective properties of the “chemistry” we are considering. You need to understand that under normal operating conditions of the treated sample (in a dry place, protected from precipitation), flame retardants of the same nature will be equally effective. And often the average coating life declared by the seller is just another attempt to increase the cost of their products.
About the composition. Usually they write vaguely: “an aqueous solution of the target components”, “fire retardant salts, biocidal additives”, etc. It is simply not possible to find out what exactly is inside a jar, canister or bag by studying the label. As a rule, nothing innovative, so we recommend watching the video at the end of this chapter.
Manufacturers. There are many of them and they have a hard time due to great competition. Hence the abundance of products of different packaging, with different names and other marketing tricks. From our experience, we can say that fire bioprotection is being prepared by everyone today. Therefore, it is better to trust trusted manufacturers, and at the first doubt, ask for a certificate of conformity.
As promised, we invite you to watch an educational video, especially relevant in difficult times of crisis. It presents one of the fire protection options for wood, which contains boric acid and sodium carbonate. A liter of such impregnation will cost about 10 rubles, and its effectiveness will be no worse than the ready-made solutions sold.
This is one of the most popular options for homemade mixtures. If desired, you can find other solutions on specialized forums, for example, based on potassium carbonate (potash), etc. The essence remains the same.
TOP 5 manufacturers of fire-bioprotective compounds for wood
What have we done? We took the 5 most popular companies involved in the production of paint and varnish products and examined the compositions they offered with the protective properties that interested us. Two goals were pursued: to clearly show the difference in characteristics between individual brands and to calculate the unit cost of processing one square meter, for example, a wooden wall. For the calculation, we took the cost based on the most popular packaging with a weight close to the minimum possible.
1. Senezh (“Senezh-preparations”)
Under the SENEZH trademark, a whole line of wood protection compounds is produced in Russia. Regarding our topic, the manufacturer offers two products to increase resistance to fire and fungal and bacterial attack: SENEZH OGNEBIO and OGNEBIO PROF. Let's try to figure out what changes are typical for impregnation with the prefix “prof” in the name. For convenience, we summarize all comparison parameters in a small table.
| Purpose | for protection against fire, flame spread | for protection against combustion, ignition, flame spread |
| for protection against rot, mold, blue stains and wood-boring insects | ||
| Average fire protection period | 3 years | 5 years |
| Average bioprotection period | 20 years | |
| II | I or II | |
| no (transparent composition) | yes (colored composition) | |
| Consumption, g/sq. meter | 600 (II gr.) | 600 (I gr.) or 300 (II gr.) |
| Packaging, kg | 5, 10, 65, 70 | 5, 25, 75, 80 |
| Approximate price* | from 700 rub. for 10 kg | from 620 rub. for 5 kg |
* – indicated for comparison with other products
We calculate the cost of processing one square meter: when using OGNEBIO - 42 rubles. (II gr.), choosing OGNEBIO PROF – 74.7 rub. (I gr.), 37.3 rub. (II gr.).
Note that it is not without reason that we put these impregnations in first place. Protective materials from this manufacturer are in greatest demand in the Russian Federation.
2. Neomid (“EXPERTECOLOGY-NEOHIM”)
Products manufactured under the NEOMID brand appeared on the Russian market more than 10 years ago. During this time, its popularity has reached unprecedented heights, and therefore fire-bioprotective compounds for wood from this manufacturer are in great demand in the CIS. At the time of writing, the company’s catalog included 4 products for protecting wooden structures from fire and biological effects. Their characteristics are summarized in the table below.
| Purpose | to protect wooden structures from ignition and flame spread | Provides protection against ignition, burning and flame propagation | ||
| bioprotection: against mold, rotting, insect damage | ||||
| Average fire protection period | up to 7 years | |||
| Average bioprotection period | up to 10 years | |||
| Fire retardant efficiency group | II | I or II | I | |

| Approximate price* | 340 rub. for 5 kg. | 660 rub. for 5 kg. | 1030 rub. for 5 kg | 6000 rub. for 25 kg. |
* – indicated approximately for comparison with other products
We calculate: when processing a square with NEOMID 450 - 27.2 rubles. (II gr.); NEOMID 450-1 – 33 rub. (I gr.), 19, rub. (II gr.); NEOMID 001 SuperProff – 123.6 rub. (I gr.), 103 rub. (II gr.); NEOMID 040 Professional – 60 rub. (I gr.).
In the video below you can see a short advertising review from the manufacturer of the fire retardant-antiseptic Neomid 450. A little about what the composition is, how it works and how to apply it. The houses will subsequently be set on fire and the effectiveness of using a fire-retardant composition will be demonstrated. Please note that the camera is temporarily taken away from the “right” house, but we are very suspicious and believe that at that moment someone helped it go out. See for yourself!
In general, be that as it may, NEOMID products have all the necessary certificates, which guarantees their high quality. The choice is up to the buyer, since there is plenty to choose from.
3. Pirilax (“NORTH”)
Izhevsk manufacturer NPO NORT offers 6 options of fire-bioprotective impregnations (four from the Pirilax group + a couple of others) for both interior and exterior work. The company sells its products with the branded prefix “biopyrene”. Let's look at the main technical characteristics of these compounds.

* – for comparison only
We calculate: when treating 1 m2 of wood with Lux, the costs will be 108.4 rubles. (I gr.) and 69.6 rub. (II gr.); Classic – 86.7 rub. (I gr.) and 55.4 (II gr.); Terma – 74.4 rub. (I gr.) and 47.5 rub. (II gr.); Prime – 50.2 rub. (II gr.); OZONE-007 – 27.2 rub. (I gr.) and 18.2 (II gr.); MIG-09 – 7 rub. (I gr.) and 3.5 rub. (II gr.).
The range of products from the North company is quite large, but the price for it can hardly be called affordable. This applies to ready-made Pirilax formulations. Below we suggest that you familiarize yourself with a video review and comparison of Russian fire-bioprotective compounds, among which one of the solutions discussed above also appears. Despite some flaws in the purity of the experiments, the video turned out to be quite educational.
4. Woodmaster, Pyrex (“Rogneda”)
NPP Rogneda is another large Russian manufacturer of paint and varnish coatings, whose product range includes fire-bioprotective compounds for wood. There are three branches to choose from: Woodmaster, Pirex and Ecodom. Let's look at their capabilities in two tables below.
| Purpose | transforms wood into a highly flammable material with protection against biological damage | transforms wood into a highly flammable material with two-level protection against biological damage, can be used to impregnate fabrics | transforms wood into a fire-resistant material, provides bioprotection under normal operating conditions |

We continue to count: for a square of wood treated with PIREX FireBioPROF, you will have to pay 99.2 rubles. (I gr.) or 63.7 rub. (II gr.), PIREX DECOR – 173.4 rub. (II gr.), ECOD HOUSE OGNEBIO – 19.8 rubles. (II gr.), ECOHOUSE OGNEBIOPROF – 28 rub. (I gr.) or 16.8 rub. (II gr.).
The video below provides a brief overview of the Wood Master line of fire retardants.
5. Olympus (Descartes)
As another popular manufacturer of paints and varnishes, let us cite as an example the products of JSC Descartes. It was not by chance that we chose it - the company has been developing and manufacturing protective and decorative compounds for wood and stone since 1992. At the time of writing, the company’s product range included only two types of fire-bioprotective compounds produced under the Olymp brand: Fire-bioprotection group 1 and Fire-bioprotection group 2. The main properties are clear from the name. But let's take a closer look at the technical characteristics of this product.
We calculate: with the indicated values, processing one square meter with the composition of 1 group will cost 40 rubles, 2 groups - 17.6 rubles. As in most other cases, the difference in price to achieve the first and second efficiency groups is approximately twofold.
About reviews
As for reviews about the use of compositions for wood treatment, only a small number of buyers who decided to experimentally verify the effectiveness of the use of impregnations can objectively evaluate the fire-bioprotective properties. For example, they bought the composition, applied it to the board and threw it into the fire, observing the further development of events. In most cases, all of the above types of fire protection met expectations. The main thing here is to buy material produced by a company that is well-known, and also not to run into a fake - buy in branded stores or large construction markets. Therefore, we will not once again advertise individual products here, especially since no one pays us for this.
Finally
In conclusion, I would like to wish that the composition you choose protects the wood from biological effects, and you would never have to find out how effectively it resists fire. Take care of yourself!

Wood, with all its advantages when used as a raw material for building materials, has a couple of serious disadvantages: it burns well and is just as easily attacked by insects and fungus. It is not surprising that owners of private houses are interested in finding compounds that improve the fire-retardant properties of wood. Let's try to help with the choice and present in one place recommendations and reviews on the use of certain compounds, and also answer the main question: how to choose the best fire protection for wood?
What is fire protection for wood?
There are about five hundred fires in Russia alone every day, millions of rubles are spent on eliminating the consequences. Just think: it burns out in about half an hour! And it’s good if the damage is measured only in money. Is it worth explaining why such great importance is attached to the processing of wood with special compounds? Usually, one product combines two useful qualities at once: protection against fire, as well as damage from microorganisms and insects - fire retardants and antiseptics in one bottle!
A small educational program. Fire retardants are substances that serve to prevent fire and subsequent combustion of wood and other combustible materials. Without going into the mechanism of their operation, we will stipulate that they can act in different ways: 1) when heated, they release carbon dioxide, thereby forming a non-flammable “cushion” covering a layer of wood; 2) when heated, form a fireproof swelling layer on the surface of the treated material; 3) at the processing stage, the fire-bioprotection solution clogs the pores of the top layer of wood, and, being a non-flammable component, literally reduces the percentage of combustible composition in the surface layer of the material. - substances that work against microbes, rot, mold, etc., and even against insects, for which wood is a tasty morsel. It so happened that to optimize the process and process the same critical structures, it is quite possible to use a 2 in 1 solution. This is what led to the wide popularity of fire-bioprotective compounds for wood.
7 simple rules you need to know when choosing
- There are no miracles. The tree will catch fire sooner or later – it’s a matter of time. But sometimes the minutes count, on which someone’s life depends. The facts are that wooden buildings not treated with fire retardants burn faster than those treated.
- 1 or 2 group. In total, there are three groups, but only the first two are important for protection; in short, then: group 2 - retardation of flammability, group 1 - retardation of flammability and combustion. Those. The first group allows you to take fire protection seriously and provide the maximum possible protection.
- The price is determined by consumption. The problem is that the packaging and concentrations of solutions can vary significantly, hence the difference in the consumption of the composition for treating 1 square meter. meters of surface. Don’t be lazy and estimate how much it will cost you to achieve the first or second group of protection when treated with one or another composition - don’t just compare the cost of the packages.
- Specific properties. When choosing fire protection for wood processing, it is necessary to consider whether the structure will subsequently be exposed to moisture or changes in temperature conditions, whether it will be hidden from view by finishing materials, or whether it is planned to apply decorative layers over the treated parts. Because there are compositions that are resistant to external influences, some with dyes (to control work) and transparent ones - depend on the working conditions.
- Everything is subject to time. The effectiveness of protection decreases over time. The usual period is up to 5-20 years, after which it is necessary to carry out treatment again. But the gap can be seriously shortened if the operating conditions of the structure are violated: exposure to moisture, freezing of structures, etc. Here it is necessary to make a small digression and explain the duration of the protective properties of the “chemistry” we are considering. You need to understand that under normal operating conditions of the treated sample (in a dry place, protected from precipitation), flame retardants of the same nature will be equally effective. And often the average coating life declared by the seller is just another attempt to increase the cost of their products.
- About the composition. Usually they write vaguely: “an aqueous solution of the target components”, “fire retardant salts, biocidal additives”, etc. It is simply not possible to find out what exactly is inside a jar, canister or bag by studying the label. As a rule, nothing innovative, so we recommend watching the video at the end of this chapter.
- Manufacturers. There are many of them and they have a hard time due to great competition. Hence the abundance of products of different packaging, with different names and other marketing tricks. From our experience, we can say that fire bioprotection is being prepared by everyone today. Therefore, it is better to trust trusted manufacturers, and at the first doubt, ask for a certificate of conformity.
As promised, we invite you to watch an educational video, especially relevant in difficult times of crisis. It presents one of the fire protection options for wood, which contains boric acid and sodium carbonate. A liter of such impregnation will cost about 10 rubles, and its effectiveness will be no worse than the ready-made solutions sold.
This is one of the most popular options for homemade mixtures. If desired, you can find other solutions on specialized forums, for example, based on potassium carbonate (potash), etc. The essence remains the same.
TOP 5 manufacturers of fire-bioprotective compounds for wood
What have we done? We took the 5 most popular companies involved in the production of paint and varnish products and examined the compositions they offered with the protective properties that interested us. Two goals were pursued: to clearly show the difference in characteristics between individual brands and to calculate the unit cost of processing one square meter, for example, a wooden wall. For the calculation, we took the cost based on the most popular packaging with a weight close to the minimum possible.
