Processing a wooden house, how to process a wooden house. How to properly treat the inside of a wooden house? Treatment of a wooden house after construction

A house made of wood is the best housing invented by humanity in the entire history of intelligent existence. Eco-friendly, warm, natural material is available everywhere, but to increase its service life and preserve its natural beauty, wood needs special protection. Let's consider what to process wooden house outside for protection, how to make it durable and maintain the attractiveness of the exterior.

Before the advent of industrial sawmills, when wood materials were harvested using an axe, there were fewer problems with the durability of the tree: when cutting with an axe, the internal pores were reliably sealed. Now, when wood is sawed, the pores remain open, and this speeds up the process of wood destruction.

The most common defects:

1. Rotting of the ends of logs due to different evaporation rates along and across the grain of the wood.
2. Fungal infection leads to the appearance of mold and causes discoloration; mold is dangerous for asthma patients and allergy sufferers.
3. Infestation by woodworms, termites or ants leads to the gradual destruction of structures.
4. UV radiation causes photoaging, which is when wood appears shabby due to a gray tint.
5. Rotting of wood due to high humidity also leads to loss of structure bearing capacity and the destruction of the house.
6. In the event of a fire, charring occurs; in the event of a fire, well-dried wood burns out completely.

These and other defects can be avoided with the help of modern protective equipment.

Wood protection products

Wood protectants can perform one or more functions:

• Antiseptics are drugs that protect against biological damage - mold, moss, algae and woodworms and prevent rotting in a humid environment.
• Fire retardants are preparations for fire protection.
• Complex drugs that perform several functions.

Different impregnations are designed to perform different tasks:

• To prevent damage to wood during the pre-construction period.
• For treatment during operation when renewing the protective coating.
• For the treatment of damaged wood.

Preparations can be based on organic compounds, water-soluble based acrylic resins or combined. Organic-based impregnations are classified as difficult or non-washable and increase the durability of buildings by 25-50 years. During processing, they change the color of the wood, helping to control the quality of processing.

Water-soluble compounds are best used in dry rooms or as a primer for external treatment, followed by protection with varnish.

To protect residential buildings made of wood, non-toxic preparations are used that do not emit substances harmful to human health. Preparations intended for use on outdoors, are not suitable for protecting interior wood.

Protective compounds can be basic (primers), finishing ( decorative compositions) and complex, combining the functions of a primer and finishing coating. The drugs are produced ready for use or in the form of a concentrate. Complex preparations are preferable because they reduce the number of treatments: one composition will protect the wood from UV radiation, pests, rot and mold, impart fire-retardant properties and tint at the same time. Complex impregnations are in demand when using wood in conditions of high humidity and high temperature, especially in steam rooms and saunas.

An important quality of wood protective preparations is vapor permeability: the composition must provide the tree with the ability to “breathe,” that is, release accumulated excess moisture into the atmosphere, otherwise the process of rotting begins.

• Belinka, Slovenia.
• Tikkurila, Finland.
• ALPINA, Germany.
• Teknos, Finland.
• AQUATEX, RF.
• Yaroslavl paints.

The product lines of these brands include formulations for various purposes:

• Primers for primary treatment followed by painting.
• Paints and enamels with different textures.
• Azure.
• Varnishes for finishing, including tinted ones.

IMPORTANT: Do not apply preparations to icy or frozen wood.

Protecting the ends of the logs

In production, the ends of the logs are subjected to primary processing, which must be renewed every 5–7 years. Since the process of absorption and release of water vapor through the ends occurs an order of magnitude more intensely than across the wood fibers, the end cracks and deforms much faster than the longitudinal surface of the log.

Protective agents form coatings that are impermeable to air, which normalizes the rate of moisture evaporation. When choosing the best way to protect the ends, give preference to compounds that hydrophobize wood to a greater depth, for example, the preparation PU-Holzverfestigung. The ends of the log house inside the building also need protection.

ATTENTION: Wood preservatives must be compatible with compounds for subsequent decorative finishing. It is better if they are from the same manufacturer.

Fire protection of wood

Primary treatment with fire retardants deep penetration It is easier to produce in a factory, where there are special baths for this. After building a house, initial treatment can only be applied to visible surfaces, which significantly reduces the effectiveness of the compositions. After the guaranteed period of action of the protective drug has expired, periodic renewal of fire protection is required.

Load-bearing structural elements (beams, rafters) require fire protection group 1. When purchasing a fire retardant, you must read the product data sheet and instructions for use, since not all compositions are able to provide the required level of fire protection.

For fire protection of baths and saunas, there are profile compounds that ensure the safety of wood in conditions of high temperature and humidity (Pirilax-Terma, etc.).

IMPORTANT: To control the quality of application of the drug, choose formulations with a tinting effect in shades natural to wood.

Bioprotection of wood

Fungal spores cause a change in the color of the tree, followed by rotting. Antiseptic compounds penetrate deeply into the pores of wood and disinfect it without increasing hygroscopicity.

Antiseptic treatments can be:

• short-term action, for the period of transportation and pre-sale storage;
• preventive, in construction conditions;
• long-term, to restore protection;
• medicinal, for infected wood.

Before purchasing a composition, carefully study the properties of the preparations: purchasing a complex-action composition that protects against all types of damage (rot, mold, woodworms, etc.), imparts fire-retardant properties and at the same time tinting will reduce processing efforts, time and money. It is also necessary to distinguish between compositions for internal and external treatment.

Wood processing

In factory conditions, wood is treated with liquid compounds and performed in special baths. In construction conditions, impregnation is carried out with a brush, roller or spray.

Before applying the composition, a set of preparatory work is carried out:

• Cleaning from contaminants.
• Grinding.
• Dust removal.
• Primer.

In some cases, when using complex preparations, primer is not required. In any case, application protective compounds produced on the recommendation of the manufacturer, who stipulates:

1. Temperature regime.
2. Number of layers.
3. Composition fixation time.

Let's sum it up

Protective compounds will help increase the durability of wooden buildings several times, while re-coating is required every 5-7 years. Complete protection of wood involves the application of an antiseptic, fungicide, insecticide and fire retardant. Complex preparations reduce the number of treatments, time and money. Façade protection products may not be suitable for indoor use.

Treatment wooden house outside from all possible unfavorable factors will prevent uneven settlement, discoloration, and cracks, and ensure its attractiveness for many years.

Many people prefer to buy or build houses made of wood, as they are attractive in appearance, warm and environmentally friendly. However, such buildings require additional protection from the negative effects of environmental factors. Therefore, it is very important to consult in advance on the features of external and interior decoration at home or contact a specialized organization for help. Our company’s specialists perform high-quality processing of wooden houses in the shortest possible time.

Cost of treating a wooden house outside

Why do you need to treat a wooden house?

The following factors can adversely affect the integrity of the house:

• Hit sun rays on the surface, from the influence of which the log house becomes darker, porous, easily absorbs moisture, as a result of which aging and cracking of the log occurs.
• Precipitation and high moisture, due to which products can swell and dry out, causing mold and mildew to form.
• The appearance of insects in the walls that damage the integrity of the wood.

Do you want to protect your building as much as possible from these adverse effects? – You definitely need to carry out internal and external treatment of the house.

Stages of impregnation of a wooden house outside

This process occurs in several stages:

• application of antiseptics;
• use of fire retardant impregnation;
• final finishing.

When working outside, specialists use an antiseptic that penetrates deeply into the wood and protects against moisture, mold and microorganisms. After this, fire retardant impregnation is applied. This stage begins a few weeks after using the antiseptic composition. Fire retardant coatings should be applied in several layers. And at the very end you can begin the final finishing.

A house made of wood necessarily requires the application of an antiseptic composition. Eat different types wall coverings: varnish, paint, plaster, brick cladding, siding. Before applying any coating, the walls must be treated with solutions.

The solutions are as follows:

• acrylate paints, resistant to external factors;
• glazing, emphasizing the natural shade of the tree, and covering, hiding it;
• oil paints are well absorbed.

The process of internal processing of a wooden house

When carrying out interior work, water-based products that do not emit toxins and are odorless are most often used. Moreover, they are moisture resistant. In the process of interior finishing, craftsmen first use the composition for the top layer, and then (after it has dried) they apply fire-resistant impregnation to the working surfaces. The next step is to apply paint or varnish to the walls of the house. At the same time, you can choose the desired shade, since today manufacturers produce products in a wide color palette.

A wooden house provides people with the opportunity to enjoy the comfort and coziness of environmentally friendly housing. But at the same time, a tree is a living organism, and wooden buildings need more care than brick and concrete structures. Natural phenomena such as rain, wind, sun, not in the best possible way affect wood, which ages and collapses under their influence. Insects and microorganisms, which are very fond of the woody structure, where they feel nourished and warm, make their contribution. Treating the outside of a wooden house with special antiseptic agents that protect the wood from the negative effects of natural and biological factors will help prevent destructive processes.

Living in a house made of untreated lumber poses a danger to humans, since fungi and mold appear on the wood, which are harmful to health, bugs settle in and eat the wood, and rotting processes begin to develop.

If these processes are allowed to develop uncontrollably, then after a short period of time the wooden house will become uninhabitable. Timely treatment will prevent all these unpleasant phenomena.

Any wooden house, both new and old, needs treatment. For a new building there are three stages of processing:

1. Antiseptic treatment of logs and beams at the production stage or self-treatment at the construction site before the construction of the structure.
2. Treatment immediately after construction.
3. Coating the house with an antiseptic after going through the shrinkage process, 6-12 months after construction.

An old log house must be treated every 3-5 years, depending on the finishing method and the quality of the material.

What to process log house outside? The answer to this question depends on what problems need to be solved using processing. There are several groups of products designed to protect external walls wooden house from various negative factors:

1. Antiseptics. Designed to protect wood from mold, fungi, microorganisms and insects. These drugs prevent wood rotting and also effectively combat existing foci of biological damage.

Antiseptics are presented in two types:

• Impregnating, hard-to-rinse compounds. Impregnations are deeply absorbed into the wood structure and are not washed out for years, protecting the wood from biological influences.
• Coating preparations. After treatment with these products, a protective film is formed on the surface, which does not allow moisture to penetrate into the wood. Film-forming compositions are especially relevant for bath treatment, because they are resistant to high temperatures.

1. Whitening products. Designed for lightening wood. The preparations whiten areas covered with a blue coating and at the same time destroy fungi that cause darkening of the wood.
2. Fire retardants. Gives wood resistance to open fire. A wooden surface treated with this product does not ignite instantly, as unimpregnated wood usually ignites, and can withstand open flames for several hours.
3. Preservative impregnations. Ensures the safety of wood. Impregnating compounds are responsible for the smoothness of the surface and prevent cracking and the formation of unevenness.
4. Primers. Primers have protective properties, protecting the wood from external influences. In addition, they provide good adhesion of paints and varnishes to wooden surface. It is recommended that before painting the exterior walls of the house, coat the wood with a primer.
5. Protective and finishing compounds (varnishes and paints for wood). They are primarily intended for decorative finishing of log walls, but at the same time they have protective properties.

Exterior treatment products are used to protect the external walls of a wooden house, which are constantly exposed to harsh outdoor conditions: ultraviolet radiation, precipitation, temperature changes.

In this regard, the main requirements for antiseptics for external use are resistance to any manifestations of bad weather and provision of reliable protection of wood from adverse natural factors.

It should be noted that many types of antiseptics intended for external work have a persistent bad smell and contain harmful components. For external compositions such indicators are acceptable, but when working with them you should be careful and use protective equipment.

There are products for a wooden house that combine different properties: they protect the wood from rot, mold, insects, fire and at the same time form a decorative coating on the surface. The value of such compositions is low, since they are ineffective. The best results can be achieved by using several highly specialized products.

If impregnation is required for raw wood, the moisture content of which is more than 20%, it is necessary to use alcohol-based preparations. Alcohol molecules promote deeper penetration of the antiseptic into the wood structure.

Concentrated products are much more expensive than drugs diluted in the factory. However, the consumption of the concentrate is an order of magnitude less than the ready-to-use composition. When using a concentrated drug, it must be diluted strictly according to the manufacturer's instructions.

To decide what is the best way to treat wood, you need to take into account the following factors:

• range of problems to be solved;
• product consumption per 1m2;
• number of processing layers;
• method of applying the composition;
• resistance of the drug to natural factors;
• guaranteed service life.
• what effect does the drug have (preventive or therapeutic).

1. Primary. Carried out by lumber manufacturers or performed during construction. It is especially important to properly treat the elements of the log house in contact with the soil, because they are exposed to moisture more than other parts. This lower crowns logs, piles, subfloors, foundations, external and interior walls basement
2. Preventive. Healthy wood is subjected to this treatment in order to prevent the formation of mold, mildew, insects and prevent rotting processes.
3. Medicinal. The treatment is carried out on a tree that has foci of biological damage. Therapeutic agents stop rotting, kill fungus and mold that have penetrated deeply into the layers of wood.

Please note that preventatives should not be applied to diseased wood. Preventive antiseptics cover the wood with a film under which microorganisms will continue to quietly multiply. Therapeutic agents can be applied for preventive purposes if the home is expected to be used in unfavorable conditions.

Stages of external processing of a wooden house

The processing process consists of the following stages:

1. Application of antiseptic. A deep penetration antiseptic is used, which is applied in one of three ways: with a roller, a wide brush or a spray gun.
2. Treatment with a fire retardant is carried out two weeks after applying the antiseptic. Usually for effective protection 3-4 layers of coating are required.
3. The final finishing is carried out no later than two months after antiseptic treatment, since the protective agent can be washed off by precipitation. Finishing options: external walls can be varnished or painted, or decorative plaster or cover the surface with siding or clapboard.

The ends are the most vulnerabilities log structure, intensive absorption and evaporation of moisture occurs through them, which leads to deformation and the appearance of cracks. Therefore, treatment with protective agents is of particular importance when it comes to the ends of a wooden house.

Protective compounds create a breathable film at the ends that repels moisture and regulates evaporation. Depending on the condition of the ends, the preparations are applied in three to five layers. Single processing is undesirable. It is recommended to use oil- or water-based products, for example, the water-soluble antiseptic Belinka has proven itself.

If there are deep cracks at the ends affected by fungus and rot, it is necessary to use a deep penetration compound. It is advisable to treat with preparations that change the tone of the wood, this makes it easier to control the degree of application.

Primary treatment is carried out during construction, re-application of antiseptic is required every 5-7 years, during which time the previous coating is usually washed off.

Features of treating wood with antiseptic

The antiseptic is applied only after cleaning, sanding and degreasing the surface to be treated.

It is best to start treating external walls from the shady side of the house. First, damaged and problem areas are treated.

If the log house was erected in the summer, the antiseptic must be applied no later than two weeks after construction.

A winter log house made from timber with natural moisture should not be treated immediately, since the composition sub-zero temperatures It will freeze, and in the spring it will thaw and wash away. It is advisable to start work at a temperature of at least 10 degrees.

Processing of a house made of laminated veneer lumber can begin immediately after construction, regardless of the time of year.

Difficulties in self-processing

Many owners wooden houses it seems that antiseptic treatment of the external walls of a log house is easy and simple work. Indeed, if you look at it, there is no difficulty in treating with an antiseptic, but only if the work is undertaken by knowledgeable and trained specialists who have repeatedly carried out the treatment and know all its intricacies.

If non-professionals try to do the treatment, then, as a rule, they find it difficult to choose a drug and do not know how to apply the product correctly. But right choice antiseptics and compliance with the technology of its application are the most important conditions for high-quality and durable processing.

Home craftsmen also make other unforgivable mistakes:

• due attention is not paid to surface preparation;
• one layer of antiseptic is applied, which guarantees short-term protection of the wood;
• processing is carried out at low temperatures.

All this affects the quality of processing and requires repeated work.

Antiseptic treatment of a wooden house is one of the main services provided by the Master Srubov company. Our specialists carefully and thoroughly approach the selection of preparations for processing logs, taking into account all the features of a particular object. We guarantee fast and high-quality processing, which will protect your home from any adverse influences for many years.

A wooden house is rightly considered best view housing based on the combination of environmental friendliness, naturalness, low heat loss and affordable cost of the material. But the tree needs special preparation to grow life cycle home and preserving the natural beauty of wood texture. So how to treat a wooden house, and how to properly protect the structure and improve its appearance?

Reasons and purposes of wood protection

The main problems that arise during the operation of wooden houses are directly related to the natural properties of the material. In the process of preparing and carrying out the construction cycle, preliminary drying, waterproofing and thermal insulation of floors and roofs at the point of contact with chimneys and hot pipes are provided. But this is not enough. The most common reasons for material deterioration are listed below.

• Cause of defect: Different speed evaporation through the end and side faces
• Manifestation of the defect: Cracking, rotting of the ends of the frame.
• Result: Deterioration in the appearance of the log house, reduction in the quality of the walls.

• Cause of defect: Fungal infection
• Manifestation of defect: The appearance of mold, blue discoloration, change in wood color.
• Result: Deterioration in appearance. Gray mold causes many diseases and is especially dangerous for allergy and asthma sufferers. Once white mold appears, restoring the tree is extremely difficult.

• Cause of defect: Damage by wood-boring beetles
• Defect manifestation: Appearance of channels with eaten away wood
• Result: Reduced quality of structures.

• Cause of defect: Ultraviolet rays
• Manifestation of the defect: The wood fades and acquires a gray tint.
• Result: The house looks shabby.

• Cause of defect: High humidity
• Defect manifestation: Wood rotting.
• Result: Structural destruction, danger of ceiling and roof collapse.

• Cause of defect: Fire hazard
• Defect manifestation: From charring to fire.
• Result: Partial damage to structures and up to complete destruction Houses.

All of these problems can be easily avoided with the help of antipyrite and antiseptic impregnations for a wooden house, protecting buildings during the construction and repair stages.

Types of wood preservatives

Chemical means for processing wood materials are divided into two large classes:

• Antiseptics, providing protection from moisture, damage by fungi and algae, from the development of rot, damage by wood borers, crustaceans and shell fouling.
• Fire retardants to protect a wooden house from fire and the spread of flame during fire.

Both specialized products and complex-effect formulations are produced. Based on the type of base, water-soluble (acrylate) and organic compositions are distinguished. The latter can be produced on the basis of highly volatile, wax or oil compounds.

To treat the outside of a wooden house, compositions with an organic base are often used, as they are more effective and difficult to wash out. However, organic compositions may contain toxic substances, which limits their use. Acrylate-based antiseptics are safe and cheap, but often require either additional paint protection or have restrictions on use, for example, only under awnings or under siding.

According to their intended purpose, the drugs are:

• primers(basic), providing comprehensive protection and conditions for deep penetration of decorative coatings;
• decorative(finishing), enhancing basic protection, protecting against fading under the sun's rays, allowing you to give the wood the desired shade or degree of shine. Suitable for treating a wooden house inside or outside, as well as for enhanced protection wet areas baths and saunas.

By consistency protective agents come in liquid (ready-to-use or requiring additional dilution), paste and solid concentrates, which are diluted before use.

processing of a wooden house from the outside. Photo

Different types of drugs may be intended for one or more of the following purposes:

• for primary preventive treatment of materials during transportation, before construction or start of operation;
• for periodic renewal of protective impregnation after the period of active exposure has expired;
• for treating damaged wood.

When choosing protective equipment for export products, we recommend paying attention to the compliance of the composition with international safety standards.

Means and methods of wood processing

Protection of critical structures

Types of processing:

• primary for structures operated in conditions of active contact with soil or atmospheric moisture (lower crowns, joists and subfloors, basements, piles, pillars, wooden roofs, gables, cladding of log houses);
• preventive for walls and partitions;
• medicinal for damaged surfaces.

Popular brands:

Nortex-Lux, KEDR-MV, Senezh, XM 11, Senezh Bio, KHMBB, XHS, Senezh Ecobio, "Biosept-Ultra", Drevotex.

Impact principle

Antiseptics for primary treatment, penetrating deeply into the wood, prevent the development of fungal diseases, mold, bacteria, woodworms, and also protect against the most dangerous enemy of wooden buildings (house fungus, although to a lesser extent than from fungal cultures of moderate rot.

Preparations of this type are difficult to wash off or indelible, and they actively act the entire time they are inside the treated structures. Life time wooden elements can grow for 25-50 years, depending on operating conditions. When applied, the color of the wood usually changes to better control the protection process.

For walls and partitions of dry rooms, colorless antiseptics are used, usually washable. For this reason, they are usually used inside the house, but they can also be used when treating a wooden house outside as a primer for subsequent paint or varnish treatment.

Some non-washable antiseptics contribute to the rusting of ferrous metals, so carefully read the instructions if you plan to treat adjacent areas with an antiseptic. metal structures elements.

Do not work on icy or frozen wood.

Protect treated structures from moisture until the product is completely fixed in the material. Usually the time is indicated on the packaging.

Protection of log house ends

Types of processing:

Popular brands:

Woodmaster Biotor, Neomid 440, Senezh TOR, PU- Holzverfestigung.

Impact principle

Through the ends, moisture is absorbed and evaporates 10 times more intensely, which causes deformation and shrinkage cracking, which is especially severe for round timber. Protective agents form on end surfaces breathable coatings that repel moisture from the outside and normalize the rate of evaporation. Some preparations, for example, PU-Holzverfestigung, cause deep hydrophobization of wood cells, continuing to protect the ends even after cracks appear.

The use of such treatment on the outside of a wooden house is extremely important and can significantly reduce both the number and depth of end cracking. Especially critical structures should be treated inside the house. The products are applied to the surface with rollers, brushes or sprayers once or in several layers with intermediate drying (determined by the properties of the end surface). Products are available in oil (wax) or water based.

To reduce overall consumption, choose oil-wax products.

If the ends are already cracked or rotting, then select a deep penetration product that can protect the damaged wood.

For critical areas, choose compounds that slightly change the shade of the wood so that you can carefully control the application process.

Pay attention to the compatibility of the product with subsequent decoration of the ends, for example, with tinting or texture compounds.

Fire retardant treatment of floors and rafters

Types of processing:

• primary before using lumber (immersing in a solution) or after building a building (applying the composition with a spray, roller, brush);
• periodic after the fire protection period of the previously applied product has expired.

Popular brands:

Senezh Ognebio, Senezh Ognebio Prof, Negorin-MS, Ultan, HMHA, Pirilax-Lux, Pirilax-Terma, KEDR Zashchita-PPP, KEDR-AN6, MIG-09, OZONE-007, KEDR-KD.

Impact principle

You can improve the protection of a wooden house from fire by two types of means: coating compositions (paints, pastes, varnishes, coatings) and impregnating fire retardants. In most cases, impregnating compositions not only protect wooden structures from fire and flame spread, but also have antiseptic properties. Contains fire retardants (flame retardants, substances that enhance the effect of retardants (synergists) and stabilizers that limit the consumption of synergists.

Fireproof treatment of a wooden house inside. Photo

Provided fire protection properties (1 or 2 groups. For particularly critical structures, which include rafters and ceilings, fire protection group 1 should be achieved. To do this, increase the number of applied layers, as recommended in the instructions for the drug, although there are also means to achieve high protection in 1 pass. Attention! Some surface impregnation preparations can provide only group 2 fire protection.

Use wood color-changing compounds to protect your most critical structures. This way you will be able to visually monitor the quality of the antipyrite treatment.

To control the application of preparations when treating the inside of a wooden house, use products with decorative tinting in shades natural to wood.

Do not allow contact with atmospheric moisture or drip-liquid moistening until the preparation is fixed in the wood.

Use specialized drugs for antipyrite treatment of baths, saunas, hammams, for example, Pirilax-Terma.

If protection is required wooden structures with previously applied paint coating, it is convenient to use water-dispersed thermal intumescent paint KEDR-KD, which provides fire protection group 1 at temperatures up to 60°C in rooms with humidity up to 80%.

Protection against blue stains and mildew

Impact principle

Fungal pores, penetrating into damp wood, form local colonies that change their natural color to blue, green, black or pink. If left wet for a long time, the tree may rot. Antiseptic agents with a fungicidal effect penetrate into damp wood and sterilize it. This eliminates the increase in the hygroscopic characteristics of wood.

Treatment is possible in three ways: immersion in an antiseptic, applying the solution with a brush or spraying. The protection time for freshly sawn wood materials can be 4 (8 months for different brands subject to proper ventilated stacking. When applied in several layers and without subsequent leaching of the product after treatment inside a wooden house, the period of protection against fungal damage can be up to 45 years.

When choosing an antiseptic, evaluate the full range of its effects in order to reduce the effort and cost of complex treatment of a wooden house. Many fungicides additionally protect wood from woodworms. Some manufacturers also guarantee protection against algae, house fungus, cracking, or increased fire resistance.

Treatment of a wooden house from mold inside. Photo

Not all brands are suitable for treating the inside of wooden houses, and some of those that are suitable will then require washing out the antiseptic before painting or varnishing. Please read the instructions carefully before purchasing.

When using compounds externally, pay attention to weather resistance. Some manufacturers indicate the need to protect facades from prolonged exposure to water with awnings or siding.

Protection from woodworms

Types of processing:

• preventive before the start of construction and installation work;
• periodic when the effectiveness of the drug has expired;
• medicinal at small area wood damage.

Popular brands:

Lignofix Stabil, Drevotex-Bio, Woodmaster Anti-bug, Belinka Belocid, Belinka Fentin, Antishashelin.

Impact principle

Many antiseptics have a barrier insecticidal property, penetrating several mm into the wood and making the subsequent development of wood borers (shashel) impossible. It is precisely because of the limited impregnation layer that it is advisable to treat healthy wood even before the construction of the log house, since the use of chemicals with a large degree of damage does not make sense.

How to protect a wooden house. Photo

When biological damage begins, the beams can be cured. To do this, a bioantiseptic solution is injected (syringed) inside the bugs' passages as deeply as possible, and then the passage is sealed so that the antiseptic can penetrate into the thickness of the beam. If the affected area is extensive, then other treatment methods are used: fogation, fumigation, microwave treatment, dry steam, and insecticides. All of them will ultimately cost more than treating a wooden house with antiseptics for prevention.

Most drugs kill only adult beetles, but Antishashelin is also effective against their larvae, provided that you manage to inject the drug deep enough into the affected wooden structures.

For deeper penetration of the drug, apply the product up to 3 times with an interval of 2 (3 days).

The period of effectiveness of bioantiseptics can reach 10 years, which is significantly longer than common insecticides. We recommend repeating preventive treatment after the expiration date specified in the instructions.

Wood bleaching

Type of processing:

Popular brands:

CEDAR Bleach, Nortex-Bleach, Senezh Neo, Bioshield-2, Neomid 500, Senezh Effo, Drevotex-Bleach.

Impact principle

When wood darkens as a result of fungal attack, only the surface layers are usually affected, especially if there is regular moisture supply. You can disguise the defect, but it is better to return the original shade with special bleaches that penetrate inside and kill fungal mycelium on the surface and in the body of wooden structures. Bleach can be grouped into two main types:

With active oxygen. Mild impact without destructive effect on the structure and without the release of harmful gases. Typically two-component formulations requiring sequential application or mixing immediately before treatment.

When choosing how to treat a wooden house, keep in mind that the treatment procedure with gentle brands containing active oxygen is a little more complicated than with chlorine-containing products. To treat the outside of a wooden house, it is often easier to choose an aggressive bleach, but for interior use it makes sense to work with mild detergents.

Decorative external and internal processing of a wooden house

Types of processing:

Popular brands:

Tikkurila Valtti Akvacolor, Tikkurila Vinha, Tikkurila Valtti Color, Tikkurila Valtti Color Satin, Tikkurila Valtti Color extra, Luxens, Belinka Lazur, Belinka Top Lazur, Belinka Top Lazur+UV, Belinka Top Lazur Mix, Belinka Interior, Krasula, KRASULA for baths and saunas, KRASULA for tinting, Krasula For interiors, Senezh Aquadecor, SENEZH Sauna.

Impact principle

Glazing, texturing, tinting antiseptics are intended for finishing a wooden house outside and in the interior; they can be applied directly to wood material or over primers on the same base (water or organic). The purpose of decorative treatment (slow down the aging of wood, reduce cracking, protect from moisture and dirt, prevent damage to flexible wood or bugs.

Varieties for saunas and baths, in addition, are characterized by an increased hydrophobic effect (the ability to repel moisture from the surface). At the same time, the natural texture and smell of wood is preserved. Some products (for example, SENEZH Sauna) have an additional antimicrobial effect and destroy common types of pathogens of infectious diseases in humans.

The compositions can be colorless or tinted in natural wood shades various breeds. There are also matte, satin (polished) and glossy preparations. Many glazing antiseptics can be tinted. After applying antiseptic impregnations for a wooden house in areas of high abrasion (stairs, railings, terraces), additional protection with varnishes is advisable.

For deeper penetration of glazing antiseptics into wood, the procedure for wall treatment should include preliminary cleaning of old coating and dust, application of primer compositions (we recommend choosing antiseptic primers from the same company on the same, aqueous or organic, base with the finishing composition).

Do not use exterior treatment products in the interior unless specified in the instructions. Compositions prepared on an organic basis have a better degree of protection, but may contain toxic substances and have an unpleasant odor.

Chemical protection at home (affordable and effective method prolong the original appearance, delay the aging of wood, protect the house from fungal and biological damage, and the danger of fire. Along with preserving the natural beauty of the wood texture, you can simultaneously refine the color of the walls, add gloss to the facade, and increase the overall lifespan of the house by several decades.

Processing a wooden house. Video

Wood has long been one of the most durable and environmentally friendly materials. Therefore, it is used in repair and construction. She has high level decorativeness, which is why consumers often choose it to decorate their apartments and houses. However, wood acts as a “living” material. Therefore, it needs processing that prevents spoilage and rotting. Wood can be treated with synthetic agents and traditional methods. They will be discussed in the article.

Using traditional methods

Protection of wood from moisture and rot can be carried out folk remedies. They have many advantages over synthetic compounds. This type of treatment is cheaper. It is environmentally safe and hypoallergenic. In addition, it is available to any home craftsman.

Wood can be treated with propolis and sunflower oil. For this purpose, materials are taken in a ratio of 1:3. They should be mixed well and applied to a surface that has been previously cleaned of dust using a soft sponge. This method of protecting wood from moisture and rotting is good because it is as strong as possible and helps prevent the formation of microorganisms. However, it has one big drawback, which is that the material has an increased ability to ignite. Therefore, you should consider whether it is advisable to use such impregnation in each individual case.

Quite often, consumers use iron sulfate to treat wood. To do this, you should purchase a ready-made solution that mixes well. A soft sponge or rag is dipped in it, which is used to impregnate clean wood.

Protecting wood from moisture and rotting with iron sulfate is ideal for round logs, since the product is not too expensive. Also extremely effective. With strong impregnation, the material will be ready to serve for quite a long time, without requiring additional protection work. The only downside of this product is the long drying time.

Wood impregnated with iron sulfate should be left in the open air, and exposure of the material to sunlight should be avoided. You can use a special canopy for this. The material is left to dry from a week to a month.

Use of bitumen and automobile oil

One more excellent option Protecting wood from moisture and rotting with your own hands is the use of bitumen. This method is effective, but from an environmental point of view it is not completely safe. This is due to the fact that concrete has the ability to release harmful substances when heated. For this reason, the use of bitumen is not always recommended.

Does not apply completely environmental materials and automobile oil. However, it is widely used for wood processing. Oil can protect against rot, mold and bark beetle, but it will not prevent fire, but will only contribute to it when exposed to flame. Therefore, this remedy cannot always be used.

Using the Finnish method

Protecting wood from moisture and rot can be done using the Finnish method. It is expressed in the use of the following materials:

• salt;
• flour;
• water;
• iron sulfate;
• dry slaked lime.

The method is harmless, but is used to process the material that forms the basis of fences and roofs. The composition has unique properties, which prevent its rapid washing out with water. To prepare the mixture, the components must be mixed to form a paste. Its main part will consist of flour and water. The composition is heated over low heat, then applied to the tree in warm in two layers. After the first layer has completely absorbed and dried, you can begin applying the second.

Use of water-soluble antiseptics

Wood can be protected from moisture and rot by using water-soluble antiseptics. They are able to create a kind of barrier on the surface, but from constant contact washed away with water. Therefore, after application, such a mixture must be periodically updated.

Among others similar decisions Ammonium and sodium silicofluorides can be distinguished, which are odorless powders. They become transparent upon contact with water. Impregnation with their help must be carried out very carefully so that the composition completely penetrates the fibers.

Another treatment option is sodium fluoride. It is a white powder and is easily washed off with water. This substance has one big advantage, which is expressed in the fact that it does not cause corrosion of the metal that may be in the tree. If you want to protect wood from rotting and moisture, then you can use imported substances that contain the following components:

• zinc;
• chlorine;
• sodium;
• potassium borax.

Such mixtures will be more expensive, but they protect the wood perfectly. It is not recommended to use them in residential premises, as they are not so environmentally friendly and can emit toxic substances.

Use of organic and oil pastes

In addition to the above antiseptics, you can use special organic substances and pastes. They consist of water-soluble antiseptics, silicon fluorides and binding components. The materials are resistant to moisture, so they can be used for processing external wooden structures. Over time, the paste is washed out, so it must be periodically applied to the base.

To better protect structures after treatment, they should be covered with a construction waterproofing film. Wood can be protected from rotting and moisture by using oil antiseptics. This should include technical oils that are toxic. Among their main advantages are high antiseptic properties.

The material is not washed out by water and protects the wood from almost all types of fungus. Oil-type compositions have a pungent odor and dark brown color. In a residential area, such an approach to protection is impractical, while oil antiseptics are excellent for piles, utility poles and bridge supports.

Using drying oil

Protecting wood from moisture and rotting with drying oil can also be done. For this purpose, some varieties of the mentioned composition are used. Among others, semi-natural mixtures should be highlighted, which allow the formation of a hard film with a high level of gloss on the surface. The base becomes water resistant. Semi-natural drying oil is good because it can be used in combination with paints and varnishes or as a primer.

Modifiers are added to combined formulations to improve the quality of the mixture. You can use combined drying oils not only to protect wood, but also as a preparation before applying paint or plaster. When protecting wood from moisture and rotting with your own hands using drying oil, you should not forget that the liquid will dry out within a day or more. During this period, no coat of paint or plaster should be applied. Synthetic drying oils can be used for impregnation, and also act as a basis for diluting dark oil paints. Synthetic drying oil is excellent for external treatment.

Products for wood in contact with the ground

Wood can be protected from moisture and rot in the ground using NEOMID 430 Eco. It is suitable for creating a reliable barrier on the surface of a material that is in constant contact with the ground during operation. This substance is an antifungal antiseptic with non-washable properties.

The material can be exposed not only to contact with the soil, but also to the influence of ground salts, as well as precipitation. The composition can also be used to coat external walls, bearing structures beams, floors, joists and beams. The mixture is excellent for door blocks and window openings.

This means of protecting wood from moisture and rot can be applied to rafter systems, fences and hedges, as well as structural elements that are exposed to difficult atmospheric conditions and low temperatures. The described impregnation is radical. It is suitable for difficult operating conditions.

Antiseptic impregnation "Senezh"

Senezh can be used to protect wood from rotting and moisture. This antiseptic impregnation has a filter that reduces the exposure of the material to sunlight. The composition is transparent. It is suitable for new and previously treated walls with antiseptic. Among the main properties are absorption into wood fibers and the formation of a weather-resistant material on its surface. polymer coating, which is distinguished by its dirt- and water-repellent properties.

The number of layers applied can vary from 1 to 3. Approximately 60 g of composition will be needed per square meter with a single layer application. You can apply impregnation using a roller, brush or spray. This type of protection dries to touch within one hour, while the base can be used three days after application.

Protecting wood inside the sauna

When choosing to protect wood from moisture and rotting in a bathhouse, you should pay attention to Tikkurila Supi Arctic. This acrylic copolymer belongs to the M1 environmental class. Water is used as a solvent. The product is applied with a brush to a dry surface, where a film is formed that prevents the absorption of moisture and dirt.

Another colorless impregnation is “Tikkurila Supi Saunasuoya”. It has a barely perceptible odor and contains anti-mold components.
