Deep penetration impregnation for wood test. Fire bioprotection of wood: what and how to choose? Antiseptics for terraces, gazebos and open areas

1.1 Antiseptic and fire protection for wood "Sigma D" with specialized additives "PYRO-STOP" developed by technologists of the company "Sigma Color" and "Sigma Plus" designed to protect wood from fires, stops the progress of fire in the event of a fire (arson of a wooden structure)

1.2 The agent is a solution of acidic compounds with specialized additives "PYRO-STOP" and specially developed bioprotective wood additive "Living House +" for private and civil housing construction, does not form a film (wood "breathes"), provides surface fire resistant to washing out by atmospheric precipitation protective layer and long-term protection of wood, and also has an aesthetic appearance after application. The structure of the tree appears.

1.3 The agent protects wood from biological destruction caused by various types of wood-staining, mold fungi and woodworm, destroys pest larvae. It removes the already existing bio damage to the tree and prevents the emergence of a new one.

1.4 Used for fire - bioprotection of external wooden surfaces (walls, parts of the roof, fresh log cabins, etc.) and internal wooden surfaces of premises (walls, ceilings, truss systems, attics, attics, basements, etc.).

1.5. Antiseptic and fire protection for wood of the Golden Style series does not dry on the surface in 20 minutes. when exposed to heat and does not freeze when sub-zero temperatures, and absolutely everything goes into wood.

1.7. Does not cause allergies. A voluntary test of fire-bioprotective impregnation for the presence of harmful substances and the effect of the composition on human health was carried out.

1.8. The composition is certified.

2. PREPARATION FOR APPLICATION

2.1 The surface to be processed must be free of dust and dirt.

2.2 The surface should not be previously treated with impregnating, paint-and-lacquer and other compositions. If necessary, apply "Sigma D" to another composition, you need to make a "trial color" to check for compatibility.

2.3 For better absorption of the composition, the moisture content of the wood should not exceed 25% - 30%. It can be applied to wetter wood to prevent darkening of the wood during atmospheric drying of lumber and wooden log cabins on shrinkage.

2.4 Due to the fact that the composition is corrosive, containers for its storage and application equipment should be made of plastic or stainless steel. Equipment must be thoroughly washed and dried after application.

3. SURFACE TREATMENT

3.1 The agent is ready for use, it is not subject to dilution.

3.3 The product is applied to the wood by brush, spray or dipping.

3.4 In the process of processing and drying, the product tints the wood in a rich amber color. On pine and spruce wood, it shows the structure of wood due to the reaction of the composition to the resins contained in the tree. The veins of wood with a high resin content become darker and more pronounced. It is possible to apply finishing coatings.

3.5 CONSUMPTION OF ANTISEPTIC FOR WOOD:

- for wood preservative not less than 100 g/m² (in one layer). Depending on the degree of damage to the surface, the composition is applied in 1-2 layers.

- for the transfer of wood to the 1st group of fire retardant efficiency in accordance with GOST R 53292 - 2009 (mass loss less than 9%), the product is applied in an amount of at least 450 g/m². (not planed wood)

- for the transfer of wood to the 2nd group of fire retardant efficiency according to GOST R 53292 - 2009 (mass loss less than 25%), the product is applied in an amount of at least 200 g/m². (not planed wood)

- for bioprotection of wooden log cabins on exposure up to 150 g/m².

- for bioprotection of wooden log cabins during assembly the joints of the logs are impregnated in 3 layers under the brush with a total consumption of up to 450 g/m². Wait complete drying composition is not needed.

- profiled timber impregnated with a total consumption of 350 g/m².

- lining, planed board, polished wooden surfaces impregnated with a consumption of not more than 200 g/m². It is possible to apply a finishing coating.

-cavities with a consumption of 450 g/m².

-ends of logs, beams and boards are most susceptible to biodamage and are impregnated under the brush in 3 passes with an intermediate drying of 60 minutes. The depth of impregnation is 3 - 7 cm. After applying the antiseptic to the ends of the timber and logs, it is necessary to make a finishing coating.

3.6 Depending on the density of the wood, the composition is applied one or more times, the drying time between layers at normal temperature and humidity - 60 minutes, at negative temperatures, the drying time between layers increases to 3.5 hours.

3.7 Treated wood can be coated with any paints, varnishes and other compounds that do not contain calcite, chalk, lime, cement 15 days after application of the product or apply Sigma Oil-Wax topcoat for interior and exterior use, 25 color solutions or similar formulations from another manufacturer.

4. SAFETY

4.1 The agent belongs to moderately hazardous substances (hazard class 3 according to GOST 12.1.007). It does not have a cumulative effect. It has a weak irritant effect on the mucous membranes of the eyes, respiratory tract and on damaged areas of the skin.

5.2 The agent is stored in tightly closed polyethylene containers at a temperature environment from minus 50º C to plus 50º C.

5.3 At a temperature of - 25º C, it partially crystallizes, after defrosting it retains its properties.

5.5. Shelf life 5 years. Does not precipitate.

Processing a wooden building of any type involves the use of antiseptics. However, before starting such manipulations, you should choose the best variety of it so that the wood lasts for as long as possible. It is worth taking advantage of the experience of professionals and paying attention to the fact that they try not to use too much expensive funds which are ready to demonstrate high efficiency. It is important to determine what functions an antiseptic should perform deep penetration for a tree. This is because universal means are not as effective, so you need to use directional formulations.

Substances for protection against fungi

Fungal formations begin to appear in the wood that is operated in a humid environment. The material is soon covered with spores. Experts advise in this case to use one of two means, among which one can single out the antiseptic brand PAF-LST, as well as Homeenpoisto-1. You can buy them on the market of relevant goods for an average of 110 rubles per liter. Do-it-yourself wood preservative can also be created. These substances are different high efficiency, consist of a mixture of engine oil waste with copper sulphate. In some cases, fumigation of the room with sulfur is used, but this approach cannot be called safe.

Bioprotection of wood in special conditions

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

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

Antiseptic for wood of natural moisture

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

Antiseptic for unbarked wood

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

Priming antiseptics

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

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

Tinted bioprotective antiseptic

If you decide to choose antiseptics for the Senezh deep penetration tree, then you can prefer a tinted type substance, which allows you to achieve an even color. Choosing the best composition, it is necessary to pay attention to the availability of skills and abilities of the master. Indeed, when applying varnish, it will be quite difficult to achieve an even layer, and in the end you can get a “camouflage” of color. This effect can be avoided by using a tinting antiseptic, which is covered with a transparent varnish on top.

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

Bioprotective antiseptic with ultraviolet filter

Deep penetration can perfectly protect also from ultraviolet rays that can damage the material. Among other things, the paint on the walls without such protection will soon fade and lose its characteristics. Among the most common are Neomid Bio Color. These compositions are also distinguished by the fact that they are allowed to be tinted in order to give the surface a shade. The walls will not be afraid not only of the sun, but also of microorganisms. You can buy such compositions for 170 rubles per liter, but in addition, the application of an additional bioantiseptic is no longer required.

Antiseptics for outdoor areas

If you choose a deep penetration antiseptic for a tree that is used outdoors, then you should choose a composition with the appropriate qualities. Thus, for outdoor areas such as terraces, it is possible to use compositions that are resistant to washout and withstand temperature extremes. The most successful solutions: Pinotex Terrace, as well as Pinotex Natural. You can buy them at a higher price, which starts at 350 rubles. However, you can count on excellent quality and durability, which in this case comes first.

Antiseptic for old wood

A deep penetration antiseptic for wood can also be intended for material that has already been painted and / or has been in use for a certain time. According to reviews, such substances are not so effective; only protective film. Experts advise to initially rid the base of old paint and only then proceed to processing.

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

wood bleaching

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

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

Antiseptics for saunas

Baths and saunas also suggest the need for processing. But wood under such conditions is unnecessarily exposed to moisture and temperatures. That is why the above compositions cannot be used here. It is not recommended to use substances that have a pungent odor. You can buy the Senezh Sauna product, which has a colorless structure and perfectly whitens the walls. After penetration, the substance creates a protective layer. And it will be possible to purchase the composition for 270 rubles.

End protection

Belonging to the group "Antiseptics for a tree of deep penetration" "Neomid" is now distributed on the market among consumers. It is often used and, if necessary, to protect the ends, which are the most accessible places for moisture. If you process the ends, then the whole building may not be processed. Areas for protection must be carefully sanded or tapped with a rubber mallet, then the master can apply a special sealant. Consumers who appreciate a good price-quality ratio choose Senezh Tor, the cost of which starts from 290 rubles. Despite the significant cost, the consumption of the composition is quite small, it is 1 liter per 15 square meters.

Fire retardant treatment

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

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 can 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

by the most important difference various formulations considered 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 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

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.

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;
• "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 fade in 1-2 years and suggest covering the tree with a mixture blue vitriol and notify. One forum member spent interesting experiment, treat the newspaper with fire bioprotection 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". Used for outdoor 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 climate zone. If on external walls rains are rare, then protection from flame will last for 5 years. Deadline for interior spaces- 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 an 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

The tree is considered to be the most eco-friendly material for building houses. Even the most modern boards (OSB, MDF, chipboard) cannot be compared with it in terms of characteristics. Hardly anyone has heard negative reviews about well-built wooden baths, country houses, cottages. Only natural wood is the "creator" of a positive microclimate and mild cozy atmosphere indoors. The only drawback can only be called a high susceptibility of the tree external influence, but on present stage This problem can be completely solved with the help of antiseptics. They significantly increase the resistance to pests and surface damage.

The term "antiseptic" is borrowed from medical terminology. It means an agent used to suppress the development and growth, as well as the destruction of pathogenic bacteria and microorganisms. In the construction industry, the concept of "antiseptic" is used to classify liquid impregnations that protect wood. It is no longer only about bugs, bark beetles, fungi and mold. Antiseptic preparations protect the tree from absorbing moisture, ultraviolet radiation, cracking, swelling, fire.

There is an opinion that an antiseptic for outdoor work is completely suitable for application to wooden surfaces in the rooms, and he will cope with the task of protection. In fact, it will be correct to use only the appropriate composition. The options used outside the building are designed to perform completely different protective functions. Often they repel moisture well, minimize the impact sun rays. Antiseptics for outdoor processing designed to protect the tree from low temperatures in winter, keep aesthetic appearance walls, frames, doors.

Among the well-known manufacturers of antiseptic agents for wood, such firms as:

• Tikkurila (Finland).
• Senezh (Russia, Moscow).
• Pinotex (Denmark, Estonia).
• Neomid (Russia, St. Petersburg).
• Belinka (Slovenia).

Main groups

Classification can be carried out according to several parameters.

1. By type of work.

Here, antiseptics are distinguished for external and internal work and universal ones, the use of which is permissible in both cases.

2. By chemical composition.

Antiseptic for wood in the form of a base may have:

• water;
• oil;
• organic solvent.

There are also combined mixtures, which increase the resistance of wood to fire. To save money, consumers have the opportunity to buy fire-retardant impregnations that work outside the building.

3. By functionality.

The following are distinguished:

• primers;
• glazing;
• covering.

4. By efficiency.

There are 4 groups of antiseptics with different levels of active ingredients:

• highly efficient;
• effective;
• medium;
• inefficient.

In turn, wood can be heavily infested with pests or fungi, have individual damaged areas, or not have problematic foci on its surface at all. To figure out which drug is suitable in each case, you need to get the advice of a specialist or listen to the reviews of competent acquaintances. A low-performance antiseptic for protecting a tree is only suitable for preventive maintenance.

Surface application

If a few years ago the use of antiseptic mixtures was carried out during the industrial processing of wood and finished products, now such funds in the widest assortment are presented on store shelves. Anyone can buy a suitable antiseptic to protect the tree. Labels or annotations inform the consumer in detail about chemical composition, operational characteristics, instructions for use.

The main application methods are:

• coating with a brush or roller;
• spraying with a spray gun.

The consumption of impregnation is usually indicated on the label. But this is an approximate number, since the absorption of the composition by a tree directly depends on its species and humidity. Quality processing requires a minimum of 2 coats.

Wood preservative is designed for a well-prepared surface, it must be dry and clean. If there are damaged areas, then start with them. Might need a fill antiseptic drug inside the lesion. In this case, use a pipette or syringe. Careful processing should be subjected to saw cuts, ends, cuts, and only in last turn move to flat areas of the tree.

In the case of repeated application, experts recommend applying bioprotective agents in early spring. This is due to the fact that all living organisms, insects, pests begin to show activity. Summer and early autumn also suitable for outdoor wood processing with antiseptic compounds. In winter, they cannot be applied, as a frozen tree stops absorbing liquid.

To effectively use the acquired impregnation, outdoor work should be carried out at a stable temperature above + 10 ° C. This will provide the necessary absorbency and drying.
