A house made of timber is an environmentally friendly housing. Only wood is able to create a unique and useful microclimate in the house, so many people choose a wooden house for their living. On the other hand, a tree is very vulnerable, humidity and other natural factors can adversely affect the condition of a wooden building that needs protection. Processing a house from a bar after construction is the first work that must be done after the construction of a log house. This operation is designed to ensure the protection of wood for the entire period of shrinkage of the house, which lasts, depending on the type of lumber, from six months to one and a half years.
Whether or not to process timber during construction depends on which lumber was purchased. Many manufacturers process wood in working conditions in special chambers, where the timber is impregnated with protective agents from all sides.
Such lumber is more expensive, but if a log house is being built from an already impregnated timber, the self-processing step can be skipped. The only thing you need is to take care of creating good conditions for its storage if construction is not expected immediately. The beam must be stored in a dry, well-ventilated place without moisture tolerance.
If raw lumber is purchased, then before building a house, the timber must be processed. How to impregnate timber during the construction of a house? Today, there are antiseptics of a new generation that provide effective and long-term protection of wood from moisture and microorganisms. One of the best means is considered "Senezh Eurotrans", which protects the beam from adverse effects for up to eight months.
If the wood is affected by fungi and darkened, but the process has not gone too deep, the situation can be corrected with bleaches based on chlorine or active oxygen. Senezh Neo, which does not contain chlorine, is recognized as the most effective, and, accordingly, has a more gentle effect on the tree.
The need for processing the log house after construction
After the house is built, it is left to shrink. During this period, no Finishing work cannot be produced, since natural shrinkage processes occur in a wooden house, as a result of which the structure is deformed.
The antiseptic that was used to treat wood in production or during the construction of a house has already expired. During the period of shrinkage processes, untreated wooden walls exposed to the influence of natural factors that have a detrimental effect on the condition of a log house.
The main enemies of the tree are insects and microorganisms, for which the wood structure is a natural habitat. Eating wood and leaving the products of their vital activity inside it, they can completely destroy wood structure and turn the tree into dust.
High humidity adversely affects wood. Wood absorbs moisture like a sponge. Under the influence of moisture, the wood begins to swell, mold and fungus appear on it, and rotting is the result of this process.
Under influence ultraviolet radiation the tree begins to lose its attractiveness and darken. In addition, UV rays lead to the drying of wood and the appearance of small and deep cracks on the surface. AT more the beam undergoes cracking for the first time after the construction of the house.
Another enemy of wood is fire, which can completely destroy a wooden house.
Treatment wooden house after construction with special impregnating agents will prevent all these adverse processes.
Most lower crowns log cabin, as well basements and other lower elements of a wooden house that are in contact with the ground or are in close proximity to it, are exposed to ground water and soil moisture. Therefore, the lower parts of the house are more vulnerable structural elements and need additional protection.
To protect them, you can use folk remedies - soak these places with a solution of copper sulfate, heated bitumen, used car oil, propolis or a blowtorch. These methods are still used in the villages, but more effective means are modern indelible or hardly washed out preparations on water based.
These products include water-soluble impregnations "Senezh" and "Senezh bio". The preparations have antiseptic properties and provide effective protection of wood from bioinjuries. They can impregnate not only the lower crowns of the log house, but the whole house. These products do not interfere with the air exchange of wood, which is especially important during shrinkage.
Another effective remedy used for processing lower parts log house, - impregnation-primer "Belinka". It penetrates deep into the structure of wood, creating on it protective layer. A tree treated with this impregnation receives reliable protection against moisture, fungus, insects and the formation of blue plaque.
Means for protecting the main structural elements of the house
Processing a wooden house is carried out in two stages:
- impregnation with antiseptic agents;
- fire retardant treatment.
There are also complex preparations that combine antiseptic and fire-retardant properties.
Antiseptics
Antiseptic preparations are divided into two large groups:
- impregnating;
- film-forming.
Antiseptics of the first group have a high absorbency and are well absorbed by wood, providing it with reliable protection. Usually, processing begins with impregnations.
Film-forming compositions, on the contrary, are most often used for final processing. Preparations of this group form a transparent or opaque protective film on the surface.
The following are recognized as the most effective:
- Neomid 440. Concentrated water-soluble antiseptic for external and internal treatment wooden structures. The drug has insecticidal and fungicidal properties, prevents wood bioinfestation by insects, fungus and mold, and also stops destructive processes that have already begun.
- Senezh Ecobio. The agent is used for deep processing of wood, penetrating well into its structure, providing a high level of biological protection. The drug is effective for the destruction of existing foci of biological damage. The antiseptic does not interfere with the air exchange of wood.
- Aquatex. Belongs to the class of hard-to-wash products. The antiseptic protects wood from damage of biological origin and the influence of adverse atmospheric factors, including protection from UV radiation. The agent is absorbed into wood fibers to a depth of 5 mm, forming a vapor-permeable coating.
Fire retardant preparations
Used for fire protection special means- flame retardants that prevent rapid ignition and allow the tree to withstand an open flame for a long time.
Among the most popular are the following tools:
- Neomid 530 is a flame retardant impregnation that provides reliable protection against fire. The tool can be used for both external and internal processing.
- KSD. The drug belongs to the 2nd group of fire-retardant efficiency, preventing the ignition of wooden surfaces. In addition, the tool protects the wood from fungi and mold.
This group of preparations allows for complex processing of wood. Using only one tool, you can simultaneously protect a wooden house from any adverse effects of biological and natural origin, as well as from fire.
Such means include:
- Senezh Ognebio. The preparation protects wood from a mold, rotting, insects and ignition. It penetrates very deeply into the internal fibers of the wood, creating a durable protective layer.
- Phenilax. The product protects the wooden house from microorganism damage, mold formation, and also prevents rapid fire.
It should be noted that at least two layers are required for effective protection. This applies to any of the above tools.

Building an environmentally friendly wooden dwelling, the owner is seriously thinking about how to process a house from a bar from the outside so that it stands and lasts longer, preferably without unpleasant surprises and regular hassle. If you have built a wooden apartment for your family, you are probably aware of the likely problems that accompany the maintenance of such a house.
Wood is an eco-friendly, fragrant, cozy material, known since ancient times and remaining attractive to this day. But compared to concrete, brick or foam block, it can also be called the most capricious. And without proper care - also the most short-lived.
Strange paradox: buildings made of wood several hundred years ago have survived to the present. And now, despite all the achievements of science and technology, at home sometimes they can’t stand even half a hundred years. I wouldn't want to be on that list of losers! This means that all measures must be taken to be able to transfer the family estate by inheritance, and it was mastered not only by children, but also by grandchildren and great-grandchildren.
How to process a house from a bar outside? This is determined by the goal that you set for yourself when using certain drugs.

What is a wooden house processed from?
Lumber, if you approach the issue impartially, is indeed quite vulnerable to many factors. In order to avoid a wide range of troubles, he needs several types of protection.
The biggest problem, and also the most common one, is the tree's natural enemies. These include molds, a long list of various kinds of fungi and an impressive list of insect pests. In order not to encounter any of these troubles, first of all, a log or block house needs antiseptic protection.
The second enemy of wood is fire. Normal lumber manufacturers treat products with flame retardant compounds even before they are sold. However, relying on the integrity of the supplier is somewhat naive. Even if he did not cheat, additional fire fighting treatment won't hurt.
The next step is moisture. The tree absorbs it a little worse than a sponge. The consequences of this process are manifested in the swelling of lumber, the accompanying deformations and the creation of favorable conditions for decay. Hydroprotection wooden house just needed.
In fourth place - ultraviolet. It mainly affects appearance log house: over time, under its influence, the tree darkens and loses its attractiveness. However, the physical impact should not be overlooked. UV rays contribute to cracking and drying of wood, which naturally reduces the quality of life in a wooden house.
At the same time, all impregnations should not prevent the tree from breathing and reacting normally to natural and climatic changes - this will not lead to anything good. Complicating matters is the fact that certain drugs, such as antiseptic and flame retardant, must penetrate the logs to perform their tasks. And UV and moisture protection, on the contrary, should create an obstructive film on the surface.
Accordingly, it is probably impossible to combine all the defenders in one tool. In theory, the processing sequence should be:
- antiseptic layer;
- fire protection;
- UV filter;
- waterproof layer.
Some impregnations combine two functions. People who believe that compounds like Toplazur, Pinotex, Senezh, Aquatex combine everything and actively promote them are wrong, which is proved by the above.
The first is only a UV protective film, the second is exclusively an antiseptic. Senezh combines bioprotection and flame retardant properties, and Aquatex forms a moisture barrier.
If you are guided by such a list, then Senezh is applied first, then Toplazur, and lastly, Aquatex.
In addition, it is worth mentioning that craftsmen who constantly deal with wood advise using narrowly targeted impregnations, although they recognize that there are relatively successful combined mixtures.
First stage of processing
An antiseptic is what you need to pay the most attention to when choosing. It is advisable to stop your eyes on water-soluble preparations that penetrate the structure of lumber most deeply. The most recommended are the following.
- Neomid-440 or 500. It is inexpensive, suitable for any kind of wood, prevents its aging for quite a long time, and lasts up to 15 years, even if there are no film coatings that prevent it from being washed out.
- Liga-Bioshield. Destroys even already born mold with a fungus and prevents their further occurrence. The impact is complemented by bleaching, which renews the appearance of a darkened log house.
- BIO-Z. It is effective even for pile structures standing in water, as it also prevents the growth of algae. The level of leaching is extremely low, the composition does not contain any compounds harmful to humans and pets.
We have already talked about Senezh. An additional property is whitening, as in the case of Neomid. - Phenilax. Meets all requirements: non-toxic, does not interfere with the “breathing” of the house, slows down aging, penetrates deep into timber or logs. In addition, it increases the fire resistance of wood.
Nuance of antiseptic coating: if it is applied throughout the log house in 2 layers, then at least 5 layers are placed on the ends of the logs (beams): in this place, the lumber is especially vulnerable to bacterial and fungal infections.
fire protection
Again, water should be the basis of fire retardant compositions. Solvent mixtures are made on the basis of flammable solvents, which reduces their effectiveness and increases the risk of fires. One recent development, and a very successful one, is a complementary blend that combines ammonium sulfate and diammonium phosphate.
When it is heated, ammonia is released, which is unable to burn, and at the same time phosphorus oxides are formed on the wood, which block the access of oxygen and prevent the fibers from igniting. The representative of this cohort is Pirilax. At the same time, it also acts as an antiseptic. In general, many drugs of the latest generation combine 2 functions: Neomid, Senezh, and Phenilax. So one less treatment.
Surface Coatings: As far as sun protection is concerned, the best choice can be considered Osmo UV-Schutz-Ol oil. Many previous UV filters necessarily contained a dye that eclipsed the natural tree view. In addition, using this composition, you don’t have to think about how to process a house from a bar from the outside to ensure moisture resistance: this oil forms a film that prevents water from seeping inside the lumber.
Painting is not just an aesthetic choice. Correctly selected and applied paintwork protects wood while maintaining beneficial natural properties, ecological cleanliness material. Raw timber absorbs dirt and precipitation, darkens and cracks.
The characteristics of wood include the reaction to changes in temperature and humidity. Paintwork materials for outdoor processing must form a mobile elastic film on the surface, which expands or contracts as the tree changes.
How to paint exterior walls
Before the use of wood coloring compounds treated with special tools penetrating deep through the pores. A house made of timber must be processed:
- antiseptics. Antiseptics create a protective barrier that prevents the penetration of insects, destroy and prevent the reappearance of fungi, blue, mold.
- flame retardants, flame retardants that increase the fire resistance of the structure.
Manufacturers often add a light dye to fire retardants. The mixture is tinted to avoid gaps during application. Then a primer layer is applied, which reduces the consumption of the main coating, leveling the absorbency of the wood.
Next stage- painting with tinted finishes.
Glazing the compositions are translucent, retain the structure of the tree, giving the desired shade.
Covering paints are used for in large numbers knots, small cracks, putty.
A dense tone will cover and level the surface, hiding imperfections, emphasizing the texture of the wood.
Color selection
Planed timber conifers quite smooth, light, easily repainted.
Wide range of colors modern impregnations provides a rich selection. In the range from classic colorless or brown shades to gold, imitation old wood- everyone will find something to their liking. Contrasting combinations of light and dark shades look interesting, highlighting the corners of the house, visors, stairs with color.
Colorless formulations do not contain UV filters the wood will darken over time. By tinting the timber with a shade close to the natural color of the wood, the original appearance of the surfaces is retained longer.
traditional light colors used in hot areas. Wood painted in white shades does not heat up, reflecting the sun's rays. Dark colors are used to absorb heat by walls in cold areas.
Coatings classified according to the degree of brilliance. The glossy finish is shiny and festive looking, but leaves all application defects, chips, dust and scratches in sight.
Matte formulations highlight the structure of the wood. The golden mean is semi-matte coatings containing up to 20% gloss.
Material selection options
New materials are gradually replacing toxic oil-based paints.
quality protective impregnations composition is classified into the following groups:
- alkyd paints, based on alkyd resin, form a rigid, durable polymer film, dry quickly;
- acrylic emulsions, contain acrylates and polyurethane in the composition of small particles, diluted with water, odorless, have a pleasant silky sheen;
- latex, or rubber emulsions. They consist of coloring pigments and latex, form a high-quality velvety vapor-permeable coating.
Preference for the quality of the coating should be given impregnations on acrylic and latex basis. Paints of these groups do not fade, do not exfoliate from the surface.
Specialized oils for wood coating on a natural basis with various pigment additives are gaining popularity.
How to paint a house from a bar?
Prepare before starting work tool for work. Depending on the height of the building and the amount of work, scaffolding is equipped or a portable ladder is used. The grinder will simplify the process of grinding surfaces.
Most of the compositions have no restrictions, they are perfectly applied:
- spray gun. The spray gun gives a thin layer without streaks, but requires skill and skill. The consumption of the mixture when applied with a spray gun is reduced;
- paint brush. The consumption of paint in comparison with the spray gun increases. The tool works along the fibers of the wood, in reverse direction stripes remain;
- paint roller. Composition consumption for square meter less, the coloring speed is faster than when working with a brush.
Prepare a container or tray for paint, rags to remove accidental smudges.
Working outside, choose the weather conditions.
Wind amplifies splashing paintwork materials when working with an airbrush, the surface dries unevenly, dust sticks.
Work is carried out in dry weather with an air temperature of at least +5 degrees.
The facade of a log house is painted in the following steps:
- Careful grinding of the surface with filling cracks with putty.
- Application of a primer with exposure of the layer until completely dry.
- Intermediate grinding of timber.
- Application of a color coating with a break for drying.
- Removing the raised pile by grinding.
- Applying the final coat of paint.
Acrylic paints half diluted with water can be used as a primer. This technique will achieve the depth of the shade.
The price of paintwork
The cost of painting a log house is added up from the cost of materials and a complex of works to cover the facade.
Comparing the price of paints different manufacturers, determine the need for the material. The square of the facade is multiplied by the consumption of the composition indicated on the package label, taking into account the number of applied layers.
On the stock and errors in the calculation add 10% to the resulting number. Paint consumption can vary between 100-250 grams per square meter. It is the total amount, and not the unit cost, that will give an idea of the costs.
For all its attractive qualities, timber requires regular maintenance. Like any other natural material, the tree is affected external factors and therefore it is necessary to take care of reliable protection. Processing a house from a bar after construction - milestone without which construction cannot be considered complete.
Why timber processing is necessary
To cover the beam after the construction of the house, special tools are used with different chemical composition- they allow you to save the tree from the following problems:
- Humidity drop. Excessive wetting damages the material to the same extent as overdrying. Sudden changes in humidity are also detrimental to the timber.
- The impact of microorganisms. Mold, fungi, insects can damage and even partially destroy walls made of natural timber - regardless of climatic conditions.
- Flammability. The dangerous feature inherent in natural wood can be neutralized through the use of refractory compounds.
Maximum protection of a house from a bar can be achieved through the competent selection of processing agents or their complex use.
External processing at home
For processing the walls of a house made of timber from the outside, various groups of tools are offered.
Antiseptics
They protect the wood from harmful bacteria and microorganisms, help to preserve the attractive appearance and quality of the timber for a long time. Such compositions are divided into several types:
- Impregnating. They penetrate into the structure of the tree and provide protection even in deep layers. Manufacturers produce impregnating antiseptics of two types - water-based and chemical-based, and the former can also be used for internal processing.
- Film-forming (covering). Needed to protect against excessive moisture. Film-forming antiseptics are divided into two groups - opaque and dense, based on resins and glazing (transparent), which do not hide the pattern of natural wood. Glazing antiseptics are washed off within 2-3 years, so the treatment must be repeated regularly.
flame retardants
Means that increase the fire resistance of timber. In the event of a fire, such a composition foams, and the tree burns more slowly. High-quality fire protection compounds are not washed off - a single treatment is required for the house.
Means of complex protection
Modern manufacturers offer tools that can ensure the safety of wood from several factors at once - high humidity, rot, mold, insects and fire. The compositions remain effective even after coating with varnishes and paints and provide protection for up to 20 years.
The choice of means for processing timber today is quite wide - compositions of a wide and narrow spectrum of action are offered by such manufacturers as Neomid, Bio-Z, Senezh and Phenilax
Stages of external processing of a house from a bar
A log house can be processed 2 weeks after the construction of the box or a year after the completion of construction - after it shrinks. It is desirable to repeat the treatment about once every three years - the frequency depends on climatic conditions.
Processing a house from a bar is recommended to be carried out in dry, but not hot and preferably calm weather at a minimum air temperature of +5 degrees. The sequence of coating a wooden surface with protective agents is as follows:
- Cleaning the surface from construction dirt, grinding, cleaning hard-to-reach places alcohol-containing (not aqueous) solutions.
- Treatment with impregnating antiseptics using hard brushes or a spray.
- Use of a film-forming antiseptic. Application of flame retardant.
When self-processing at home, it is necessary to use goggles, gloves, protective overalls or a respirator - wood coating compounds are toxic.
How to process a house from a bar inside
For the treatment of timber walls in residential premises, impregnating water-based antiseptics and special varnishes with low toxicity are used. In some cases, they try to use folk remedies- wax, a mixture of salt and slaked lime, a decoction of oak bark, blue vitriol and sulfur, but reliable and safe products with a balanced composition - optimal choice. Application sequence protective equipment inside the house is about the same as outside.
Timber houses can be built for both permanent and temporary residence, but in any case, the owners want the house to stand as long as possible. Complete and regular care per natural wood will help maintain its impeccable appearance and strength for at least one to two decades.
Wooden beam is very convenient for construction. Many buildings can be built from it: from a capital residential building to a temporary greenhouse. Wood is a strong, reliable and durable material, but, unfortunately, defenseless against destructive influence. environment, is prone to rotting, cracking when dry, or can be destroyed by wood insects. It is not difficult to avoid such a nuisance if you know how to process the timber.
What can be used to protect
In order to protect wooden surfaces from damage and destruction, you can use different means.
Various impregnations
Impregnation for timber is the most optimal means that allows you to preserve its structure for a long time and protect it from destruction. It is applied to the base before the start of decorative and design work, penetrating deeply into the wood structure, protecting it from decay or drying out. But some impregnating solutions can change the natural color of the wood - this must also be taken into account when choosing a mixture. For example, if it is planned to varnish a log house made of planed timber, preserving or slightly shading the natural shade of the material, then you need to choose transparent compositions that do not change their color after application.
Priming mixtures
The use of various impregnating primers is very convenient. A primer with additional additives will not only protect the material, but also prepare the base for application. decorative coating. When choosing a suitable primer, in addition to its priming properties, it is necessary to take into account the same features as when choosing impregnating solutions.
Varnishes and enamels
Impregnating varnishes and enamels have a high degree of protection, but, unfortunately, most of them are toxic. They are perfect for processing the building from the outside, protecting the building from moisture and temperature extremes.
homemade recipes
"Folk" methods suggest using improvised means, for example, used engine oils or ash, to protect a log house from a planed beam. But after such treatment, the material almost always loses its natural color, and the protection of the walls, as a rule, is almost never complete.
Solutions for processing can be:
- Water based, when the solvent is water.
- Based on refined products (more often these are varnishes, enamels or with an antiseptic or fire retardant added to them).
- Synthetic-based, where the solvent can be any chemical compound, are often toxic.
In order for the protective qualities of the impregnating mixtures to correspond to the operating conditions of the building, choosing the appropriate composition, the following parameters must be taken into account:
In addition, it must be borne in mind that the processing of timber in the gazebo will be very different from impregnating the walls outside or inside a residential log house made of planed timber:
Experienced craftsmen for long-term wood protection recommend:
- When processing walls from the outside, start applying the impregnation from the ends. First, the ends are well impregnated, and then the rest wooden elements. 2-3 more layers are applied to the ends, because they are the most defenseless against aggression external environment, and rotting of the material begins from the ends.
- Decorative and design work can only be started after the base has dried after impregnation.
- To save natural beauty wood, it is necessary to carefully study the instructions before purchasing the drug, which indicates whether it changes the natural color of the tree after application to the base or not.
When choosing how to process timber, you need to take into account all the nuances so that it does not rot and does not collapse under the influence of adverse factors. A house, greenhouse or gazebo impregnated with a well-chosen composition will last a long time without requiring major repairs.
