Wood, being a building material, has, in addition to a wide list of pluses, a number of minuses. The main one is susceptibility to humid environment. Protecting wood from water is the main factor that ensures the durability of various wooden structures.

For timber protection by immersion, a minimum concentration of 5% is recommended for a minimum 8 hour immersion time, but a 24 hour bath is recommended. For effective protection by effective pressure impregnation, a 1% solution is used. For long-term protection for interior spaces surface protection, deep impregnation or soaking is used. Long-term protection of wood during appearance used for surface protection deep impregnation or diving.

Potential sources of biomass. In Poland, about 1 hectare of agricultural land is collected annually, about 10 tons of biomass, which is equivalent to about 5 tons of hard coal. Taking into account the area of ​​agricultural land and the purchase of biomass from state forests, the total production of biomass in Poland is equivalent to 150 million tons of hard coal. Unfortunately, this value, unfortunately, is estimated differently in specific studies, so it cannot be the basis for calculations.

Wood quickly loses its strength due to water, so it must be well treated.

A high level of humidity can lead to a violation of the structure of wood and structures made of it. The presence of an environment with increased level moisture is perfect place for the development of microorganisms various kinds leading to the formation of fungus, mold and smoldering.

It has a much lower calorific value than coke or coal, but it also pollutes the atmosphere significantly less, giving a pleasant odor that is smokeless to residents. Hardwood species such as birch, maple, beech, hornbeam, alder are suitable for combustion in boilers. Pleasant smell and good ozing give wood fruit trees, mainly pear and plum. However, it is difficult to buy, it appears on sale sometimes when cutting gardens. The fibrous construction of fruit trees also makes it difficult to separate logs into smaller pieces and is therefore not liked by merchants.

How to treat a tree from moisture and smoldering?

The initial stage of protection against moisture is the implementation of proper drying of wood before it is used for release from it. building materials, since carefully dried wood is more resistant to the negative effects of moisture.

The calorific value of wood is largely dependent on its moisture content, resin, lignin and specific gravity. Freshly cut wood is not an efficient fuel, has a moisture content of more than 50% and contributes to corrosion of the inner surface of the boiler. Buying raw wood, you must rely on the need for seasonal use. The process of natural moisture loss, depending on the conditions, takes 1-2 years.

Table 1 The ratio of the calorific value of wood and its moisture content. Dry wood has hygroscopic properties, durable in summer sunny days can reach up to 15% humidity, but in autumn on wet days it can again rise to 25%. The content of resin and lignin is higher in softwood, while hardwood is heavier per meter, and since sales dominance occurs in spatial meters, hardwood ultimately wins the market.

Drying can be done different ways. Drying under production conditions is the most optimal, as it involves the introduction of special equipment and a strict control system over the production process. Carrying out atmospheric drying will allow to cope with the task in the conditions of the normal organization of the production process.

Table 2 Calorific value of some types of wood. When buying wood, we must pay attention to its shape. Wood in logs and logs has a much higher calorific value than small woods such as logs. It's connected with large quantity roughness in round logs in the outer parts of trees.

Table 3 Calorific value of wood depending on its size. Hardwood has a relatively short bright flame, burns calmly, "does not shoot", does not pollute the chimney and tar boiler. soft views, such as linden, poplar, and willow, burn fairly quickly and are often used for lightning. Rigid hardwoods, such as hornbeam, oak and beech, are burned very slowly, keeping the fire in the hearth. Coniferous trees, especially pines and larches, contain a large number of resin, so they burn with a high and very fiery flame, especially in the first phase of combustion.

As a result of the dangerous effect of moisture on wood, wooden building material can rot and mold. The process of smoldering wood can occur during the transportation, construction and operation of wood. The active spread of smoldering wood from moisture can be explained by the following reasons:

  • high air humidity;
  • stagnation of oxygen and lack of its access;
  • temperature fluctuations;
  • accumulation of condensate;
  • freezing of lumber;
  • contact of a tree with a layer of soil;
  • high humidity of the original wood.

To protect the tree from moisture, various preventive measures are needed, which are introduced even at the stages of storage and construction. wooden houses. The humidity level of wood materials depends on the season. Continued drying can take more than a year.

They give a lot of heat and quickly raise the temperature of the hearth, but they pollute it with greasy soot that is difficult to remove. Wood loses its moisture in the initial phase and evaporates, the wetter it is, the more heat is required to reach this phase. At temperatures above 150°C, wood gradually decays with the release of wood gas, the main combustible component in wood.

After complete degassing, about 20% solids remain, which are allowed to flow further and at high temperatures. After drying, they are an ideal fuel for boilers. They require dry, ventilated compartments during storage due to their hygroscopic properties and susceptibility to fungi and mold. Straw is largely an ecological fuel that serves the environment well. Straw ash contains a large amount of calcium and potassium oxides and can be successfully used as a vegetable mineral fertilizer.


There are several types of methods that prevent the process of smoldering from moisture. Waterproofing will help protect the tree from capillary water, and painting or installing a roof that is waterproof will help protect the tree from atmospheric moisture.

The design of a wooden house should be on the foundation, engage in installation drainage systems not worth it, but it is best to ensure high-quality drying at home. You should not arrange a garden near the house, as this will increase the humidity inside the premises.

Burning can be subjected to straw from all types of cereals, as well as straw, buckwheat, legumes, etc. in Poland, the straw is divided according to the degree of attachment to yellow straw, gray straw. Yellow straw has a higher chlorine content and is more dangerous for the boiler in terms of corrosion. An important parameter for straw is the melting point of ash. Due to the low melting point of the ash, barley straw is not recommended for energy purposes due to the phenomenon of sealing the internal surfaces of the boiler.

The technical parameters of the straw are determined by the size of the straw, which is the straw form. After determining the calorific value of the straw, ten measurements of the length, width, height and weight of the finished straw samples were carried out. These data were then converted into bulk density, specific volume, and energy concentration factor. List of received parameters - table.

The next proven way to protect against the appearance of smoldering foci is to protect wood from the ends, since the ends are one of the most vulnerabilities buildings. Inspection of the house should be taken as a rule, it is best to carry it out in the spring. Identification of the causes of rot is associated with the collection of sample materials in order to recognize the density of the building material and its level of moisture.

Straw parameters according to dimensional alignment. The energy value of straw is related to its moisture content, for most boilers this value should not exceed 22%. Straw is very light and occupies a large volume, the equivalent of 1 m3 of coal is the energy equivalent of about 20 m3 of straw. Straw does not stick, so it only shrinks both in harvesting and processing.

Table. calorific value various types straw. Straw briquettes are produced by pressing grain straw in special piston or roll presses. "Briquetting machines" have a relatively high bulk density and low humidity, making them ideal for storage. The small volume allows them to be packed in ordinary bags and stored for many years in dry rooms. Straw briquettes are usually cylindrical in shape from a few to several centimeters in diameter, but there are also rectangular bricks, oval bricks, etc. small briquettes can be burned in boilers with a screw feeder, large briquettes in boilers with solid fuel with lower combustion, gasification.

A tree affected by smoldering has greatly reduced physical and mechanical properties. The density of the tree is reduced by 15%, and the hardness becomes 20-30 times less if we compare the affected tree with the whole. The level of damage can lead to shifts outer walls and internal, distortions of the gaps of windows and doors, loosening of the entire building. An obstacle to the process of spreading the lesion can only be chemicals.

At a moisture content of 5-15%, the ash content is less than 0.5%. The disadvantages of sawdust are storage difficulties, a tendency to brew, and susceptibility to moisture. Part of the bark is processed into sawdust during wood processing. The cork must be crushed in a top hopper grinder before being fed into the boiler with a screw feeder, but the bark is fast but consumes little energy. The disadvantage of oats is the problem with its long-term storage, in the absence of sufficient ventilation and high humidity, the seeds rot and are also attacked by rodents.

The use of folk remedies to protect against fungus

The problem of choosing a means for impregnation tree species and protecting it from moisture is quite difficult, but solvable. Can be used for this purpose folk recipes. Here is some of them:

It is the most technologically advanced biomass fuel. It is a small cylindrical granule with a diameter of 6-25 mm and a length of up to several centimeters. This gives you a very warm fuel that is easy to store and burn. Review of wood protection methods.

AT recent times the treatment of seasoning from wood requires protection against pests and fungi using appropriate preparations. Nowadays more and more wooden houses used in construction frame structures, and also, and in the case of wood dried on a tree. This treatment eliminates pests and fungi. It does wooden elements that are not in contact with the weather - they do not need additional insurance. On the other hand, wooden elements that are in contact with rain, snow and dust must be protected - preferably with the right impregnations.

Treatment blue vitriol. To do this, 100 g of the substance is dissolved in 10 liters of water and the wood is treated.

  1. The use of silicate glue to protect wood from external influences. To do this, dilute the glue with water. At the same time, the adhesive composition must have a certain degree of ductility so that it can be coated with all defective places.
  2. The use of a solution of 5% potassium bichromate mixed with a 5% solution of sulfuric acid, taken in proportions 1: 1, in order to protect the tree. The composition can process not only one ceiling with walls, but also a layer of soil to a depth of 0.5 m.
  3. Preparation of the composition using soda and vinegar. All areas covered with mold are treated with a solution by spraying it from a spray bottle.
  4. Treatment of wood with copper sulphate. Why 100 g of a substance is dissolved in 10 liters of water. This solution can be used to process walls and ceilings, gaps in windows and doors.
  5. Impregnation of stakes, fences, wooden logs with heated resin.
  6. Using a solution of salt with boric acid. In this case, take 50 g of acid per 5 liters of boiling water with the addition of 1 kg of salt. Mixing with special care, treat the surface twice after a 2-hour interval.

The methods listed above will be effective if large areas are not covered by smoldering. wooden structure as this will require constructive action.

In the forest we use only a dry chamber. Read more about it in the post. Below you will find an overview available methods wood protection. Provided that they are mainly used for dried wood and wood treated with atmospheric conditions.

Properly selected impregnation allows a longer use of the wooden surface in an undamaged condition and color. Impregnation prevents the penetration of water into the wood, protects against fire, does not allow the development of mold, fungi, insects. It also delays aging and enhances the pattern of wooden cans.

Treatment of wooden houses with an antiseptic

Most effective ways, which are used to combat moisture and mold, are 2 ways:

  1. Conservation.
  2. Antiseptic.

Conservation is a method used for the purpose of processing wooden surfaces substances with toxic effects. This method is not secure, so it is used in construction industry in the process of soaking raw materials, processing by diffusion, impregnation by autoclave.

There are two types of wood impregnation. Surface treatment - depends on the external saturation of the wood by painting or spraying. Impregnation - impregnation of wood with vacuum or pressure or without pressure. Impregnations can be divided into aqueous and soluble. The first one is usually used indoors because they have good features safety, but relatively low elution resistance. However, repellent solvents are more resistant to external factors.

Different types of impregnants are available on the market for different needs and applications. Fire retardants - prevent wood burning and flame spread. Waterproof coverings - moisture resistant. Biological impurities - destroying bacteria, molds, insects, fungi and prevent their formation.

Antiseptic involves the application of chemical solutions. Processing is possible without anyone's help with a brush or roller. On the shelves of stores there is an unlimited number of antiseptics and paints and varnishes that can prevent the appearance of fungus on wooden structures. Before choosing, you need to decide on the purpose of processing.

Medications - immediately applied to surfaces already attacked by insects, fungi, mold. Combinations are also available that combine multiple uses. You can also use varnishes, stains or varnishes. Protects wood from mechanical damages of biological corrosion, water and the sun. It enlivens the color and emphasizes the pattern. Varnishing should be repeated often - once every two years. It is best to cover the wood with a colorless impregnation before painting. Before varnishing, it is recommended to apply a sample to an invisible part of the wood.

White spirit and compositions based on it or using water can be used not only for the purpose of safety, but also be in demand due to their low price. Impregnation of wood structures with such solutions, which are most in contact with soil or moisture, will not bring the desired effect.

Protects the facade for several years. They are used on low risk surfaces mechanical damage. It is best to cover the facade with a colorless impregnation twice, and then make up twice alkyd enamel. The sticks penetrate the forest, giving it color. They support the facade for about 4 years. Etching does not significantly inhibit the growth of fungi and mold, so wood that has been seasoned rather than chamber dried is best protected with paint or wax. The reconstruction of the embroidered and non-lacquered facade consists in its matting and re-lapping.

Water-repellent antiseptics are ideal for impregnation. You should not forget about the conditions for using various compounds and their properties, which can be read on the packaging. Some of the solutions are used to treat external surfaces, there are compositions for internal views works.

The use of paint materials for external works beneficial with constant temperature changes as they are resistant to weather phenomena, precipitation, frost and sunny weather.

Blends are more resistant to mechanical influences, rather than temperature changes and ultraviolet radiation. When buying mixtures, you should definitely ask about the availability of a certificate confirming complete safety when using these products for human and animal health.

For ideal processing of wooden surfaces, it is imperative to choose a high-quality composition. There are many possibilities for treating wood from moisture and smoldering.

Popular disinfectant masks

If we turn to Russian manufacturers, then such brands as "Wood Doctor", "Bioks", "Biosept", "Aquatex", "Pinotex", "Elkon" are considered to be of higher quality.

The disinfectant composition "Wood Doctor" is used to impregnate all types of wood, regardless of the depth of the lesion. The product is environmentally friendly and non-hazardous. It is ideal for outdoor and indoor processing.

"Bioks" is a coating that protects against mold and highlights the texture of wood. The composition may be colored or colorless.

Protection of the tree from microorganisms is carried out with special antiseptic solutions.

"Biosept" is a composition that is intended for the purpose of processing residential wooden buildings and structures inside and out. Represents one of best means in your own area. Made on the basis of new generation biocides, it is harmless, durable, resistant to weathering, difficult to wash out, allowing subsequent changes in the color of the tree.

"Aquatex" is the most suitable for the protection of sawn and planed wooden surfaces.

"Pinotex" is a product whose manufacturer produces antiseptics, oils and paints. This composition is suitable for the purpose of processing any type of wood that does not fade after application of the composition, gives the tree a beautiful color and lasts from 8 to 10 years.

Elkon is an impregnation that includes several types of products used depending on the purpose, such as Elkon Aqua Bio and Elkon Sauna.

Foreign manufacturers may offer various formulations in order to combat smoldering, moisture and mold on wood:

  1. TIKKURILA is a Finnish company that sells glazing, covering, priming types of antiseptics. The company produces paints with an oily protective base. Before using them, you should read the annotation.
  2. Dulux is a British concern that produces antifungal impregnations and primers based on organic solvents.
  3. ALLIGATOR is a German company that offers impregnations and paints and varnishes, which fall into the structure during processing, without clogging all the pores of the tree. They are able to emphasize the natural beauty of the tree species, do not burst, dry in a short time, and retain their initial characteristics for a long period of time.

Despite the abundance of modern building materials, wood does not lose its popularity. Wood is used to build houses, baths, it is used to install various beam floors. But wooden surfaces have drawbacks - they are prone to decay, and various wood-boring insects start up in them. Properly executed impregnation for wood from moisture and decay allows you to preserve natural material longer.

Why does wood start to rot

Rotting destroys the base of the tree, the decay products released and traces of vital activity of microorganisms adversely affect the human body, causing various diseases (most often the lungs - due to the inhalation of fungal spores and putrefactive particles that enter the air).


But before choosing a composition for processing wood, you need to find out the causes of decay. It could be:

  1. The destructive effect of atmospheric phenomena. Under the influence of wind and temperature changes, the tree begins to dry out and crack, and moisture entering the cracks favors the germination of fungal spores. The destructive processes that have begun in the wood attract insects (mainly wood-boring bugs), and this additional factor contributes to a more rapid destruction of the wood structure. To protect the tree on the street, you should select an antiseptic for outdoor work, which will provide protection from exposure environment and scare away woodworms.
  2. High humidity and insufficient ventilation. In wet rooms (sauna, bath, close-fitting cellar) ground water) the evaporation of moisture is slow, and if there is not sufficient ventilation, then water penetrates into the structure of the wood and lingers there long time. The constant moisture of wood fibers creates favorable conditions for the development of the fungus. A similar situation may arise in living rooms at home, when, due to insufficient heating in cold weather, moisture accumulates in the corners and a whitish mold appears.
  3. Constant contact with earth or water. In this case, there is direct contact with moisture and various microorganisms, which increases the risk of mold and fungi.

The composition of the antiseptic must be selected taking into account the factors affecting the surface.

How can you protect the wood structure from destruction

There are several ways to protect wood from moisture:

  • waterproofing (prevents the penetration of water to the surface of the wood);
  • providing sufficient ventilation to remove moisture;
  • protective impregnation with antiseptic.


Waterproofing and ventilation cannot give a 100% guarantee of protecting the material from fungal infections and rot. Therefore, they are recommended to be used in addition to impregnation with an antiseptic, which may differ according to the following criteria:

  1. Place of application. For outdoor work, it is necessary to choose mixtures not only with increased moisture resistance, but also with resistance to temperature extremes.
  2. toxicity. Some formulations with high protective qualities are highly toxic and should not be used indoors. For outdoor use, toxicity does not matter.
  3. The nature of the active substance. Separate organic and inorganic. Organic ones last longer, have a high protective ability, but are dangerous for the human body.
  4. type of solvent. May be water or have a different basis. Aqueous are considered non-toxic. On the construction market in 2016, a wide range of water antiseptics with great protective qualities, suitable for both indoor and outdoor use, was presented.
  5. Depth of penetration into the wood structure. Some solutions penetrate deep, filling the pores of the wood and preventing the penetration of moisture, while others create a waterproof film on the surface.
  6. Validity period. Some compositions provide protection for 3-5 years, others, especially those made by hand, are effective for a short time (1-2 years).

Impregnations can contain only one antifungal antiseptic, but in most cases manufacturers offer comprehensive protection from rot, insects, fungus and fire.

Varieties of impregnating solutions

Conditionally everything protective compounds for impregnating wood can be divided into several groups.

Water repellent

They have high fluidity and penetrate deep into the wood structure. Such antiseptics are recommended for use in places with high humidity (bath, kitchen). Even the accumulation of water on the floor or walls does not affect the protective qualities of the composition. Moisture-repellent preparations are recommended for the treatment of sleepers, wooden poles and other products in direct contact with the ground or water.


Oily

They have a small penetration depth and form a thin, durable film on the surface. The downside is high toxicity and the fact that oil mixtures can only be applied to dry products.

water soluble

Eco-friendly, easy to use and dry quickly. Ideal for rooms with moderate humidity. They can process not only wood, but also plywood, chipboard and other derivatives of wood.

Volatile

They are made on the basis of varnishes or paints. Such antiseptics penetrate shallowly into the structure of the tree, but when dried on the surface, they form a thick, durable film. Well suited for outdoor work or for finishing non-residential premises. Toxic and take a long time to dry.

In the market of paint and varnish products in 2016, all these varieties are represented by different manufacturers in a wide range. Each master can choose an impregnating agent, taking into account the characteristics of the wood product used.

How to choose the right impregnation

When choosing a suitable antiseptic, the following parameters must be considered:

  1. Action on fungus and mold. If the impregnating composition is purchased for preventive treatment, then it is enough to take a standard composition. In the case when a “treatment” of a tree already damaged by a fungus is required, it is recommended to choose a more active formula of active ingredients.
  2. impact on wood. Some mixtures not only kill mold and insects, but also damage the structure of the tree (more often this is a change in color).
  3. degree of penetration. The deeper the solution penetrates into the wood fibers, the more effective the protection will be.
  4. Resistant to temperature extremes. This parameter is important for outdoor work.
  5. Validity. The time during which the antiseptic mixture retains its ability to resist microorganisms.
  6. The presence of an odor. Even a non-toxic composition with a pungent odor is not recommended for use in a residential building - bad smell will create discomfort.
  7. Safety. In places where people live or there are pets, only non-toxic formulations should be used.
  8. Consumption. Usually, depending on the viscosity of the mixture, it ranges from 100 to 400 g/sq.m.


Protective impregnations can be produced as an independent solution or included in primers, varnishes or pastes.

Home remedies

Despite the fact that manufacturers offer many options for impregnating compositions, some home craftsmen prefer to make protection for wood from fungus and rot with their own hands. The most commonly used for this purpose are:

  1. Copper vitriol. 100 g of dry matter is diluted in 7-10 liters of water and used for outdoor work. Vitriol is used to treat fences and external surfaces of various buildings.
  2. Used oil. The oil drained from the machines and outdated is used for wood in contact with the ground (crowns of the house, piles and Bottom part poles before digging into the ground).
  3. Hot bitumen or tar. Hot tar coating provides high protection wood from fungi and rot, repels insects well. Tar is used in wooden cellars and in others auxiliary premises with high humidity.
  4. Slaked lime. Regular whitewashing allows you to create a film of calcium hydroxide on the surface, which serves as an antiseptic and prevents the development of rot.
  5. salt and boric acid. 50 g of dry acid and 1 kg of salt are poured into 5 liters of boiling water. The solution is used after cooling.


How to process wood

It doesn’t matter what type of impregnation is used: a mortar, a primer or a self-made mixture, to increase the effectiveness of the product, the wood must first be prepared:

  1. Clean the surface of dirt and residue old cladding(if reprocessing is carried out).
  2. Wash. Washing increases the depth of impregnation. Smaller surfaces can be cleaned with a brush and cloth, but for larger areas a car wash (car washer with pressurized water) is recommended.
  3. Dry. Some compounds can be applied to a wet base, but most antiseptics are recommended to be used only after the wood has dried.


After preparing the product, it is recommended to dilute the mixture, as indicated by the manufacturer in the instructions. Liquid solutions can be sprayed with a spray gun, and more viscous ones can be distributed over the wood in an even layer using a roller or brush. When carrying out protective work, professionals advise:

  1. enjoy protective equipment. Impregnations are most toxic at the time of spraying, and it is recommended to work with them in a mask, goggles and gloves.
  2. Exactly observe the specified drying time if you plan to further decorative trim. Applying a primer or wallpaper glue on a wet antiseptic will provoke its “smearing”, and the protection will be uneven.
  3. During processing, even with non-toxic compounds, it is recommended to remove pets and children from the house. In addition to the fact that children and animals may be more susceptible to the components of the impregnating preparation, they can simply smear the wet layer and disrupt the quality of the treatment.
  4. It is not necessary to apply more layers for increased protection than the manufacturers recommend - the protective qualities will not increase, there will only be an unnecessary consumption of material.

If the treatment was carried out in accordance with all the rules, then the antiseptic will reliably protect the wood throughout the entire time specified by the manufacturer in the instructions.

When you want to extend the life of the building, then you should not neglect the impregnation from rot and fungi, especially since the solutions are inexpensive. It is better to prevent the appearance of pests that destroy the wood structure in a timely manner than to spend time and money on restoration.
