What impregnation for wood from moisture and decay is suitable for outdoor work. The best deep penetration antiseptic for wood

How to choose wood fire protection products

In Russia, houses, baths and sheds were traditionally built from wood. Today, timber and logs are a popular material for the construction of buildings. In order to protect the house from fire and fungus, fire bioprotection for wood is used. How best to choose a quality fire retardant? Let's look at the characteristics of different compositions and feedback on their use.

Classification, characteristics and application features

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 the 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:

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

Treatment with fire and biological protection means is necessary for every wooden structure

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:

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

Advice. The more layers, the better 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 group 1 is allowed.

Flame retardant consumption

Peculiarity protective compounds that when buying it is necessary to pay attention not only to the price tag, but also to the expense. 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.

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 action of the flame forms protective film;
"M". In the composition - blue vitriol, protecting against mold;
"FROM". 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:

"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 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.
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 climate zone. If on external walls rains are rare, then protection from flame will last for 5 years. Deadline for interior spaces- 12 years old.

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 an appropriate protective treatment. Fire bioprotective compositions, selected according to the specified criteria, will help ensure the safety of any building.

Wood is easily affected by fungus, insects, it ignites well. What fire bioprotection is better to choose 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. Also, wood is exposed to temperature fluctuations, humidity, mechanical stress, and therefore needs special protection.

Protect wood from biological pests, the flame is capable of fire protection. If you treat wood with such means, you can reduce the risk of mold, ignition.

Varieties of fire protection according to the method of their application:

covering;
impregnating (the most popular, because after the processing, you can clearly see the texture of the tree).

Choosing the right product

Senezh impregnations have proven themselves well. There are in the line "Senezh Ognebio Prof", "Senezh Ognebio". The product "Senezh Ognebio" is able to protect against fire, the spread of flame, from the occurrence of blue, rot, mold, insects that damage the tree.

The average duration of fire protection is three years, the agent belongs to the second group of fire retardant efficiency, the average duration of bioprotection is twenty years. Means consumption - 600g/sq.m. m. for the second group.

The product "Senezh Ognebio Prof" protects against ignition, burning, flame spread. It will also effectively protect against insects that spoil the tree, middle period fire protection - five years, the average period of bioprotection - twenty years.

This product belongs to the first (second) group. Substance consumption for the second group - 300 g/sq. m, for the first - 600g / sq. m.

We list the most popular brands of fire protection:

"Senezh";
Good Master;
"Neomid";
FOREST;

Product Features

There are different packaging of goods. It is not worth taking with a margin, since this product can always be purchased at the store, and if it is stored for a long time, it loses some of its properties.

Fire protection can also be called impregnations. It can be produced in the form of paste, varnish, enamel, impregnation. If you intend to use putty, paste, then it is smelly, it is better to use it in places that will then be subjected to additional finishing because it spoils a little appearance products. Impregnation does little to change the smell or texture of the wood.

If it is necessary to process 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 tool, it is worth considering whether there is SES permission for the use of this composition in residential premises, how much money is spent per 1 sq. m, fire protection efficiency group of the product, saline 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 - wood is treated with flame retardants, then it is treated with antiseptic substances.

Otherwise, fire protection can be called flame retardants. These are highly specialized goods used for processing. Wood is processed before construction begins. Need to wipe scaffolding, scaffolding, various wooden elements, as well as details of the frame of the house.

About the principles of work

Functioning principle of fire protection:

refractory substances in combination with salts of silicic, phosphoric, boric acids, there are salt-free options;
forming an impenetrable dense film;
to reduce the access of oxygen to the object, fire impregnation is capable of emitting non-combustible gases.

Fire protection is essential in the construction of residential and commercial buildings. Also, with its help, it is necessary to well process buildings belonging to the category with a high degree of fire.

The specified means is processed railway wagons, ships, ships, barges. When performing restoration work, it is also necessary to use complex protection.

Benefits of using fire protection

The advantage of using fire protection is a complex effect. If the tree is treated externally with refractory impregnation, then insects can be effectively controlled. This is due to the compounds that make up the product. Insects do not start in a tree if it is treated with antiseptic substances.

When choosing, you can give preference to the means that belong to the first group of fire protection efficiency. Consider the purpose of the material - whether it will be used for interior decoration, whether they need to process the supporting structure. So that the product does not change its color - choose colorless analogues.

The effectiveness, duration of drying is influenced by the method of application, the composition of the product. In some products, it is acceptable to use a larger amount of the agent in order to provide improved fire and biological protection.

Pay attention to how fire protection affects the material. It may swell on the surface, decompose into gaseous compounds, or melt the outer coating.

What are the best products to choose?

The most common and affordable impregnations containing carbon, phosphorus, boric salts. However, they are easily washed out with water, they need to be used more to process 1 sq. 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 processing. If you use such an impregnation, then in the future it will not be possible to cover the tree with paints and varnishes.

It is better to choose salt-free impregnations. They are able to slow down the combustion process. The bioprotection of materials treated with such agents will last a maximum of twenty years, and the fire-retardant properties will last up to fifteen years. The composition of the impregnation does not contain toxic substances that could harm human health.

In order for the substance to be well absorbed, the wood is dried. If there is an old paint and varnish coating, then it should be cleaned before applying the fire protection.

Apply impregnation in several layers. The packaging indicates how much you need to spend per 1 sq. m. One layer is applied, then allowed to dry, and the second layer is applied after twelve to twenty-four hours.

To protect the load-bearing structural elements of the house, made of flammable materials, from the likely risks of damage in the event of dangerous situation, use special means(I and II groups according to the degree of fire protection efficiency). They are part of a set of measures to ensure fire safety object.

What is fire protection for wood

This is a product of a certain composition, the use of which reduces the likelihood of instantaneous ignition of an object, slows down the rate of spread of fire. Another name is flame retardants for wood. Protective substances process a certain type of material, i.e. they are highly specialized. Application must be carried out prior to construction. It is necessary to treat with fire bioprotection not only the frame elements of the house, but also scaffolding, scaffolding and other auxiliary structures if they are made of wood.

How wood fire protection works

The fire-fighting substance has a number of properties: bioprotective or antiseptic; fire retardant. Depending on the type, the principle of operation of the composition differs:

Wood fire retardant may release non-flammable gases, which reduces the oxygen supply to the material.
Another way: the formation of a dense, impermeable film, due to which the combustion temperature of the wood increases significantly.
Refractory substances may contain a number of compounds: salts of boric, phosphoric or silicic acids. There are also salt-free analogues - their price is higher.

Wood preservative

The advantage of fire protection is a complex effect. In external processing, refractory impregnation for wood is also effective in the fight against insects. This property is ensured due to the effect on the material of the compounds that make up the composition. In this case, either salt crystals penetrate the structure, or the wood is impregnated with technological substances. In the second case, there is no film on the surface, antiseptic properties are manifested during the formation of chemical bonds between the impregnation elements and the material, which prevents insects from starting up in the structure.

Fire retardants for wood

Fire protection is provided by chemical reactions with a significant increase in temperature. Decomposition of compounds into constituent elements leads to the release of coke foam or non-combustible gases. The first of the options covers the material. When the fire is eliminated, the foam coke layer can be removed mechanically. If such bio-fire protection for wood is used, the impregnated material remains intact. When using other types of flame retardants, gases are formed, more often poisonous. This means that you need to ventilate the room well.

Fire retardant for wood

Classification is carried out according to the method of application and the principle of action:

penetrating substances (fire-retardant impregnation of wood);
special coatings.

In the first case, comprehensive protection of the tree from the inside is provided, in the second - with outer side boards are applied different types of coatings. It can be paints and varnishes, pasty coatings. All of them are characterized varying degrees fire intensity. There are saline and non-salt substances. The division of penetrating compounds into groups is carried out on the basis of the characteristics of the substances. This:

organosoluble fire and bioprotection for wood;
water soluble compounds.

The second option is very popular, because it does not require the use of hazardous solvents, which often represent a group of combustible substances. This favorably distinguishes preparations for treatment from organic-soluble counterparts. Given the characteristics of the composition of water-soluble substances, they can be divided into groups:

indelible;
difficult to wash out;
washable;
lightweight.

Fire bioprotection of wood of popular brands

To choose a high-quality and proven composition, it is recommended to study the offers on the market. Popular brands are Olimp, Senezh, Neomid, Asfor, Pirilax, Healthy Home. Besides, well-known manufacturers(TechnoNIKOL) offer products based on other substances, for example, bituminous varnish, which protects wood from insects and decay. Such materials can be selected and ordered in the catalog on the manufacturer's website or from intermediaries.

Price for fire bioprotection for wood

The cost directly depends on the intensity of the effect of the substance on the fire and the effectiveness of protection (I or II group), and additionally - on the consumption, method of application and volume of containers. If you buy fire protection in an online store, it will cost a little cheaper. The price of different types of funds lies in the range from 300 to 6,000 rubles / container. Senezh products (10 kg) are offered inexpensively - at a price of 700 rubles, a smaller amount (5 kg) can be bought for 620 rubles.

The cost significantly fluctuates depending on the amount of fire protection of wood and its properties. For example, compositions of group I of fire protection efficiency will cost several thousand rubles. In this case, consumption plays a secondary role. For comparison, the price of substances of the Neomid brand of group I is 6,000 rubles. (25 kg). Some types of wood fire protection, for example, Senezh, can be applied repeatedly, which increases consumption, but at the same time impregnation of wood. This will lead to an increase in the price of processing 1 square. m area, but will improve the properties of the material.

Protection of wooden structures from decay and fire

The wood should dry out, which in the future will ensure good absorption of the substance.
The surface is cleared. In the presence of an old paintwork it must be removed before applying fire protection.
The coating/impregnation is applied in several layers. The quantity is determined by the consumption of the substance per 1 sq. m (indicated on the package). The interval between applying layers is 12-24 hours.

How to choose fire bioprotection for wood

Increased reliability is provided by substances of group I of fire protection efficiency. First, it is recommended to pay attention to such compounds. To choose the right fire protection, the purpose of the material is taken into account: interior decoration, part of the supporting structure ( concealed installation). The shade of the substance is taken into account: the coating can change color, there are colorless analogues.

It is necessary to take into account the type of composition, differences in the methods of application. This also affects the duration of drying, the degree of efficiency. Some compounds are allowed to be used in more to provide improved fire protection. It is recommended to select a substance according to the method of exposure: decomposition into gaseous compounds, swelling on the surface of wood, melting of the outer coating. When choosing, you need to look at the container capacity and price, pre-calculate the required amount of fire retardant (approximate consumption).

Video: the best fire protection of wooden structures

Fire bioprotection is designed to minimize the fire hazard of a wooden structure by slowing down the combustion process. The flame retardant composition includes flame retardants based on boron, ammonium phosphate, ammonium chloride. Most often, fire protection also has an antiseptic property, which resists the development of fungus, mold and the reproduction of harmful insects. Characteristics that the best special tool for wood should have: do not lose your chemical properties Under the influence external conditions (high humidity, temperature differences), have a slow evaporation process, have a sufficient service life, be safe if used indoors. You can choose a tool, both according to user reviews, and independently using the information received.

Characteristics, features and properties

Due to the fact that the special equipment directly affects the fire safety technique, it is presented with many characteristics and features and has a significant difference in price. Fire bioprotection is unable to completely protect a wooden structure from fire, but it can greatly contribute to the preservation of the structure from the destructive effects of fire, as well as gain time for a rescue operation. You can find out the fire and bioprotection group by the marking on the packaging of the special equipment. According to the effectiveness of the refractory agent is divided into two types:

1st group - effectively protects against fire, the flame spreads slowly. During a fire, bioprotection allows you to save 70% of the construction area. For residential premises it is recommended to use the 1st group.
2nd group - effectively protects against the rapid spread of flame, but the product evaporates quickly, so if the reaction is not timely, the wooden building will lose up to 90% of the structure area.

Advice. the effectiveness of special equipment depends on the number of applied layers: the 2nd group of protective equipment can be equal to the first with repeated surface treatment.

An example of packaging for fire and bioprotection of the 2nd group from the market assortment

Types of funds realization

For ease of application, refractory raw materials are sold in several forms:

Impregnation. It is divided into two subtypes according to the depth of absorption: superficial - penetrate deep into the beam by 6 mm, more advantageous due to the ease of application with a brush, spray, roller; deep penetration - impregnate wood 12 mm deep, professional equipment will be needed for use. When applied, impregnations change the structure of the color, so they are applied before the final finish. The advantage of impregnation is the absence of smell, which facilitates indoor use.
Enamels, varnishes, pasty mixtures. Significantly change the color, structure of the materials on which it is applied, in addition, they have an unpleasant strong or slightly pronounced smell, therefore they are used only before the final stage of finishing work.

According to the method of dilution, flame retardants are divided into water-soluble and soluble with the help of special liquids.

Water-soluble compounds, in turn, are further divided into two types: saline, non-salt. The advantages of a salt agent are in cost, and there are much more disadvantages: a short service life (3-5 years), when exposed to moisture, it quickly loses physical properties, large consumption . Flame retardant without salt in the composition provides a longer protection period (15-20 years), non-toxic, can be used indoors and outdoors.
A solvent-based agent is used to protect the outside of the structure, due to increased toxicity. The advantage of applying such a liquid is the formation of a protective film that repels moisture and protects the effects of fire. The disadvantages, in addition to toxicity, include the narrow focus of the composition: they do not have an antiseptic property.

For the treatment of wooden surfaces from the inside, the least toxic agents should be chosen.

Classification by interaction with fire

According to the method of action during a fire, fire protection is:

Slow burning, smoldering. The slow process is provided due to the formed film of flame retardant substances. Chemical elements react with oxygen and prevent the flame from engulfing the wooden structure.
The composition of the protection emits gases that do not support combustion.
The resulting shell swells under the influence of high temperatures, and prevent the spread of fire.

Majority protective equipment They have antiseptic properties, which is why they got the name - fire bioprotection.

Abbreviation designation on the package

In the instructions for use, letter codes are indicated that indicate the special composition of the raw material. They can be used to determine whether the agent has an antiseptic property or is suitable only for protection against fire, as well as the method of action during a fire. Explanation of abbreviations:

"M" - means that the composition includes copper sulfate, which protects the building from the appearance of fungus and mold.
"F" - indicates that the substance includes sodium fluoride (NaF). Chemical element It has no smell, it is well absorbed into the surface, but it is also easily washed out. Toxic to mold and pests. Used to protect inside premises.

Attention! Sodium fluoride practically loses its properties when interacting with limestone, cement, alabaster, chalk.

"X" - zinc chloride (ZnCl2) is present in the composition. It has fire retardant and antiseptic properties. Easily washed out with water.
"B" - means that the composition includes boric acid (H3BO3), which is a flame retardant and antiseptic at the same time. Causes increased hygroscopicity of wood. At high temperatures, it turns into a vitreous film, providing fire protection.

Water-soluble, four-component, hardly washed out bioprotective impregnating composition of KhMBB marking

"D" - the composition includes diammonium phosphate ((NH4) 2 HP04). The agent containing this element is well absorbed into the wood, weakly washed out when exposed to moisture and has a small percentage of volatility. During ignition, diammonium phosphate decomposes into several elements. Ammonia creates a gaseous envelope that slows down the combustion process.
"C" - indicates the presence of soda ash, which at elevated temperatures creates a protective film that effectively slows down the combustion process. Non-toxic element, indoor use is possible.
"ХА" - indicates that ammonium chloride (NH4C1) is included in the fire protection. At a temperature of 350˚С, it decomposes into ammonia, hydrogen chloride, which significantly slows down the spread of the flame. It weathers quickly, so it is often used in mixed formulations or as a substitute for ammonium phosphate.

Criterias of choice

To ensure a high degree of safety and a long shelf life of the chemical properties of fire protection, you need to rely on the following parameters:

When building or from rounded, glued beams, the application of a protective layer is mandatory. Properly selected fire protection will help ensure high level safety, reliability and, as a result, a long service life of the entire structure.

Video: Fire bioprotection for wood

Processing wood with high-quality antiseptics can significantly increase its service life.

They are intended for effective protection wooden structures from mold, rot and decay, as well as to improve performance.

For this, specially designed formulations that meet the basic safety requirements are suitable.

Wood protection begins with the selection of a suitable preservative.

Types of antiseptics and composition

Modern antiseptics are classified by composition, purpose and scope.

Depending on the main components that were used to produce protective equipment, wood impregnation can be divided into the following types:

Water soluble;
Oily;
organic;
Combined.

water soluble

Impregnation on a water-soluble basis is intended for the prevention of wood processing various types. Wood preservative is used to protect surfaces that are not exposed to water.

For the production of water-soluble antiseptics, the following ingredients are used:

Sodium silicon fluoride;
sodium fluoride;
BBK 3 (boric acid and borax).

Oily

The most popular and demanded type of antiseptic, which is used to protect wooden structures from high moisture. The basis of such products are oils - anthracene, shale or coal.

Wood preservative gives the wood a dark saturated shade.

It does not dissolve in water, but has increased coefficient flammability and a strong oily smell, therefore it is used exclusively for external work.

organic

Impregnation organic type not so in demand and is often used to protect outdoor wooden structures.

This type of wood preservative creates a thin protective film on the treated surface, improving the moisture absorbing and bonding characteristics of the wood.

The disadvantages include the possibility of painting surfaces in green color and increase their porosity.

In addition, such products have a negative effect on metal elements, contributing to the development of corrosive processes.

Combined

Such antiseptic formulations successfully combine the performance characteristics of other types.

Purpose

Depending on the purpose, special wood protection is divided into two categories:

According to the area of \u200b\u200buse, antiseptic for wood is divided into two categories:

For interior work. Impregnation of this type is used to protect structures and elements intended for interior spaces. Therefore, it is absolutely harmless and does not have a strong smell. It is important to remember that for each type of room it is necessary to choose the appropriate antiseptic.
For outdoor work. This category includes antiseptic impregnations and finishing agents designed for processing outdoor wooden surfaces. They differ in wear resistance and resistance to aggressive influence. Compositions for external use have a specific pungent odor, are resistant to high moisture, low temperatures and ultraviolet. It is better not to use them for interior work.

Choosing the best antiseptic

Effective wood protection depends on which preservative has been chosen. To choose the right antiseptic compositions for a tree, it is important to consider some factors:

Manufacturer;
Composition;
Purpose and area of use;
Type of wood;
Consumption per sq.m.;
Impact on the human body;
Quality certificates;
Price.

A reliable wood preservative should have a high toxicity to mold, fungus and harmful microorganisms.

No less important is the indicator of protective ability. So wood protection can be ineffective, medium efficiency, effective and high efficiency.

The finished preparation must fully correspond to the degree of damage to the wood. According to this characteristic, the antiseptic can be used on clean, unstained, slightly infested and heavily infested wood surfaces.

Impregnation for interior work must have an appropriate sanitary conclusion about complete harmlessness for indoor use. Preparations for outdoor work should be different high rates resistance to low temperatures and ultraviolet radiation.

What antiseptic preparation is considered to be of high quality? One that adheres well to the surface and is compatible with any paint material.

Before buying, you should carefully read the instructions for use and check the expiration date of the drug.

It is worth refusing to purchase antiseptics from unknown manufacturers with the lack of the necessary quality certificates, because high cost is not always an indicator of quality.

Do-it-yourself antiseptic

A protective antiseptic for wood can be prepared independently, which will be much cheaper than purchased counterparts. Most often, home antiseptic formulations are prepared from iron sulphate and sodium fluoride.

Vitriolic

Pour 100 g of ferrous sulfate and 10 g of potassium permanganate into a volumetric plastic container. Add 20 liters of water and mix thoroughly. Apply the finished composition to the surface to be treated with a brush or roller.

sodium

To prepare an antiseptic, you need 25 kg of sodium fluoride and 400 liters of water.

The finished mixture is best applied to wooden surface airless staining method. After drying, the wood is carefully sanded with a petal wheel and processed with finishing protective impregnations- oil, varnish or wax.

The difference between homemade and factory-made antiseptic preparations is only in the components that are used for their production.

Ready factory impregnation is more effective due to the high content organic components. It is toxic to the human and animal body, so it should be used in accordance with the manufacturer's recommendations.

Do-it-yourself compositions are less practical and effective, while saving money. Home biosecurity is available in preparation, environmentally friendly and safe for humans. To determine which antiseptic will be the best, it is worth considering all the conditions for its use.

Proper treatment of wood with an antiseptic

The technique for processing wood surfaces is quite simple, but, nevertheless, it is important to remember the safety measures when working with chemicals of this type.

Requires a special protective clothing, mask, rubber gloves and impregnation for wood.

The surface is thoroughly cleaned of old coatings, debris and dust. Next, the wood is treated with soft detergents and dries up.
The antiseptic mixture is applied to the damaged areas with a brush or roller. The next layers are applied 2-3 hours after the first layer has completely dried. Complete drying of the treated surfaces can last from 3 days to 2 weeks.
All work on wood processing is best done at a temperature of +5 (for organic, oil and combined formulations) and at +10 (for water-soluble). Humidity is at least 85%.
To destroy insects, it is better to use alcohol compounds, which are poured into holes made by pests with a special syringe. Next, the surface is treated with the selected antiseptic.

Re-protection of wood with antiseptics is carried out in case of chips, cracks and discoloration of the surface.
