Treatment of logs with protective compounds: internal and external. How and how to handle a rounded log

To build lasting safe house made of natural wood, first of all, you should take care of the quality of the main material. In this regard, it is important not only to choose the right breed, but also the principle of log processing. Comfortable living in it in the future depends entirely on how professionally the initial felling and further calibration work will be performed, how the chosen technology fits the architectural idea of \u200b\u200bthe house project.

To give a felled tree the desired shape several technologies are in use today.

They differ mainly in the tool with which the work is done:

1. Ax.
2. Staple.
3. Electric planer.
4. Milling machine.

The chosen method affects both the future attractiveness of the entire building and the quality of strength. In each individual case, corresponding to the applied processing technology, a certain complex is preserved natural properties and add equally important characteristics created artificially in the process of wood preparation.

Advantages and disadvantages of each technology

To determine the most suitable way for a specific project, familiarize yourself in advance with all the nuances of both the processing technology itself and the further use of the material obtained during the work.

Chopping with an ax

This technology is also called debarking. This is a way exclusively self made, the most simple and, at the same time, very time consuming. The main task when doing work is only to remove the bark.

Among the advantages of this ancient method of preparing building material, we note the following characteristics:

1. Maximum complete preservation of natural properties due to the natural drying process.
2. Compaction of wood is excluded (which certainly happens when cutting). Due to this, even in the felled state, the tree continues to "breathe" and the risk of rotting inside the log is reduced due to constant air circulation through natural pores.
3. Excellent strength of the material, which does not decrease due to the preservation of all layers of the plant.

The disadvantages of this technology include the following difficulties in work:

Important! Despite such a long list of shortcomings, this old method the most natural wood processing does not lose its relevance.

Stapling

Another way manual processing logs, which is performed using special tool - scraper.

The principle of log processing is the sequential cutting of thin layers of not only bark, but also the next layer of wood - sapwood.

Important! The device of such a tool resembles a sickle in shape, only with handles on both sides. The cutting part is made of durable brands steel and is sharpened on one side.

The advantages of this method are represented by the following list:

1. Attractive appearance logs. Upon completion of the work, the internal texture of the wood, its unique pattern and shade, appears very clearly.
2. Nice texture of the material. Due to the peculiarity of processing - fine cleaning, like a blade, the entire surface of the log after such preparation is very smooth.
3. Almost complete preservation of all natural qualities... Strength and healing properties remain the same as before processing due to the fact that a small, only top, layer is removed.

This method is not without its disadvantages:

1. A very laborious process that requires strength and skills. Failure to comply with the rules of technology will significantly reduce the quality of the material obtained.
2. The duration of the work.
3. Does not remove irregularities, which leads to the necessary sealing of gaps after assembly of the house
4. Long shrinkage due to the preservation of the natural shape of the trunk.

Processing logs with a plane

The most popular method today, which gives whole line advantages.

In the process of performing all the work, the bark is removed, the irregularities of the trunk are removed, but as a result, the entire removed layer of the tree is not very thick. To perform such work, they are mainly used electrical modelsthat significantly speed up the process with little effort.

The advantages of this method:

1. Preservation of the natural hardness and density of the wood.
2. Profitability.
3. Ease of processing.
4. The speed of all preparatory work.
5. Attractive appearance, similar to a rounded log.
6. Smooth and smooth surface along the entire length.
7. Ease and speed of assembly at home.
8. Tight fit of all structural elements.
9. Shorter shrinkage period than described above technologies
10. The ability to design and houses of simple architecture and complex projects with non-standard shapes.

It is quite difficult to highlight the disadvantages when choosing an electric planer for forming a log for building a house and, in principle, they are relative:

Important! Given the noted nuances of this method, we can safely say that preparing logs for building your own log house using an electric plane is the best option.

Milling

The processing of a felled trunk on a milling machine results in the rounded log so popular today.

The barrel is fully passed along its entire length through the cutters of the selected profile. When preparing lumber of this type, a significant part of the wood, bark and all upper layer, down to the core.

An important condition in this case is the recommended impregnation with protective agents in order to exclude rapid destruction. home distinctive feature this way - all logs prepared on a machine of this type have the same diameter. The resulting blanks are logs with mathematically precisely verified parameters.

The advantages of this method include the following characteristics:

Important! Separately, we note the possibility of creating any complex curly profile with correctly selected cutters.

The disadvantages of this method include the following results:

Important! Despite all the complexity and exclusively technical side of the processing of rounded logs, the material obtained in the process of such preparation has quite an acceptable cost. This position allows you not to bother yourself long work felling and processing blanks manually, and purchase finished material the right size with high performance.

Watch the video, which clearly shows the entire sequential process of designing a rounded log.

Protective wood treatment

The ease of ignition of natural wood in the vicinity of an open fire and its susceptibility to the absorption of excessive moisture, contribute not only to the deformation of the shape of the log, but also to its complete destruction. It is also difficult naturally exclude attacks of harmful insects that destroy the material. Therefore, it is recommended to treat the log with an antiseptic before use, which reduces the destructive effect of such factors.

All means to enhance the protective properties natural wood differ in the principle of action, the composition of the components and the more suitable stage of construction for application. The range of such products is quite diverse - these are gels, and bulk substances, and pastes, and all kinds of concentrated and dry mixtures for the preparation of solutions.

Strength characteristics increase as follows:

• deep penetration of the solution into the thickness of the wood;
• the formation of an outer protective layer.

By the type of composition, the following groups of solutions are distinguished:

Watch the video showing examples of wood preservatives and their effect.

Finished log processing

All work on the design of a log house is not limited to the preparation of logs and their assembly. After 1-2 years, after the final shrinkage of the building occurs, processing of the house from a log is required. The most popular technology for the renewal and final cleaning of the surface of the logs is grinding.

The logs are processed exclusively with the help of such tools:

Conclusion

Despite the seeming ease of wood processing processes, especially those technologies that use high-quality automated equipment, one should not forget about the need for accurate design and compliance with safety measures when performing any construction works... Log handling is no exception in this regard. Correctly selected processing technology, performed in strict adherence to all standards, will provide a result that meets expectations and the built house will delight the owners with unique comfort and practicality.

Is it necessary to protect the bath with an antiseptic?
Wood is one of the most common materials used in the construction of baths. However, under the influence of negative external factors, it not only loses its original appearance, but is also affected by fungus and various woody insects. Favorable conditions for the growth of the fungus are created by high humidity, condensation, temperature drops.
Treatment of the bath with an antiseptic is an indispensable condition for its durability. Many residents wooden houses or the owners of baths are faced with the problem of how to properly protect the tree from which they are made with antiseptics.
To do this, you must read the instructions written on the packaging of these products. In addition, sellers in stores will always help you and tell you what purpose this or that antiseptic is needed for.
To begin with, you need to understand that some products are suitable for processing outside, on the street, where there is exposure to the sun, rain, wind, dust, birds. And others - for processing inside, where the walls are exposed to hot or cold water... Constant humidity and high temperatures quickly destroy wood.

Log baths are always natural and beautiful, aesthetically pleasing and environmentally friendly, besides warm. For their construction, of course, you need logs, which must be able to properly handle so that your bath will stand as long as possible. Our article will tell you how to process the logs of the bath.

Subject the prepared wood to two obligatory operations: debarking and sharpening. Debarking is cleaning a log from bark, it is usually done without any mechanized tool, manually, but only on condition that the amount of work is small. Just peel off the top dark layer of bark until you reach light wood. When you debark, you will notice that there are not very large, but noticeable areas of bast left on the log, or the so-called "sub-bark" (a fresh layer of tree bark that is separated from the trunk itself). When this layer dries, it darkens, and the tree usually becomes variegated in color, as is typical for unplaned logs. If, during debarking, the fibrous composition (fibrous structure) of the tree is not damaged, but the bast is subject to rotting, it is because of this that the log must necessarily go to the jail.
Remove the underbore (about 0.5-1 cm) with an electric plane. Guide the tool along the length of the log. Try to remove an even layer the first time, otherwise the wood will have technical creases. This will not affect the quality of the building material, but over time it will manifest itself in the unaesthetic appearance of the logs - the creases will darken, even if you cover them with an antiseptic and special impregnation. The result of correctly performed actions will be a beautiful, natural golden shade of a log, completely free of bast.

Dry the logs. This can be done in natural conditions (but taking into account the climatic conditions of the country - as a rule, few people decide to do this) or use thermal chambers where the tree is kept for up to 5 days. An unfinished tree will crack in length over time, so do not neglect this method of protecting your future bath.

Wood, especially processed wood, is susceptible to the action of molds, insects (for example, bark beetles), as well as the action of various natural factors. You have the right to decide what life span to assign to your bath, treating logs with chemical protective agents. Use modern antiseptics, insect repellents and wood-staining fungus (in the event that you are going to paint the bath).

Certainly traditional technology manual felling has established itself with the best side: in almost any settlement you can find wooden houses that are fifty, seventy, or even a hundred years old. But note that these perfectly preserved buildings were not erected by modern cutters, but by old masters - completely different people of a different mentality from a completely different time. Nobody knows how long a house made by a team of modern craftsmen-shabashniki will stand; how its walls will look in three to five years - no one can predict either.

Turning to the brigade of craftsmen, be sure to carefully consider those log cabins on which the brigade is currently working and turn your

close attention to the following:

gaps between the crowns; cleanliness of processing cups and inter-wedding grooves; absence of a large spread in the diameters of the logs of one felling; the number of potentially problematic logs in the collected log cabins (crooked, significant radial cracks); the attitude of the cutters to their product (the abundance of dirt on the logs is not just a consequence of inaccuracy, it is evidence that the workers will easily assemble your frame from half-rotten, crooked logs).

Modern technologies, as a result of their implementation, have a significant weakening of the dependence of the quality of the final result on the skill of the workers. In the case of mechanized processing, the quality depends more on the smooth running of production and the technological capabilities of the equipment.

Therefore, an individual developer, when contacting a woodworking workshop, should first of all pay attention to:

availability of mechanization during the entire cycle of work; reviews of already completed orders from previous clients; availability and availability of sorted raw materials base; the timing of the manufacture of log cabins (a long production time should definitely alert the customer, because it is a consequence of obvious or hidden problems in technological process); technological capabilities of the equipment - ask, for example, is it possible with this equipment to round the logs along the generatrix of the cone ("like a carrot"); age and technical condition production base (old and worn out machine tools are unlikely to lead to a high-quality result).

Timber harvesting methods for building a house or bath.

When harvesting wood, the trunk of a sawn tree is cut into equal pieces of approximately 6 meters in length. The thickest log, the butt, is called the "first cut". The next section of the trunk is the second cut. Etc. It is noteworthy that the closer the cut is to the top of the trunk, the more the taper of the log is observed. The first cut is practically a cylinder.
The wood structure is heterogeneous along the trunk radius. The densest layer is the outer outer layer 1-2 cm thick, located directly under the bark. If this layer is damaged, when external environment begins to contact the surface of the inner layers of wood, the log becomes susceptible to decay and subsequent destruction.

There are differences in wood different breeds... So, spruce wood is richly and evenly saturated with resin from the very early age wood; pine wood is sufficiently saturated with resin only in mature age... Moreover, mainly the outer layers are saturated. Therefore, when using small diameter logs (up to 26 cm), it is more reasonable to use spruce, as it is more durable, because pine at the age when the first cut does not exceed 26 cm in diameter is not yet sufficiently impregnated with resins and, accordingly, less durable.

On the other hand, the abundant resin-richness of mature pine wood can be of no use in rooms such as saunas or baths. From heating and high humidity wood begins to "cry", losing resinous substances and staining the surface of the log. In the case of using pine wood for hot visits, it is considered mandatory. inner lining clapboard, for spruce log cabins this operation is redundant.

One of the main disadvantages of rounded logs is precisely the short service life due to susceptibility to decay: the removed dense layer exposes the inner surface of the log, which is easily subject to destructive processes. However, when using logs of the first cut, this accusation has no grounds: the original log is an almost ideal cylinder, and peeling off a layer of bark and a few millimeters of the undercorn layer, the cylinder machine does not transform the log into a "short-lived beautiful toy".

Chopped or rounded house - which is better and why?

To illustrate the traditional process, we use photographs that were kindly allowed to be taken by a team of wood bath cutters on the jobsite.

The opponent of the classical technology is the mechanized processing workshop. The self-made cylindering machine allows you to process logs up to 10 meters long and up to 60 cm in diameter. Casing "for carrots" is possible.

Manual felling is cheaper, so a manual felling is more profitable than a log cabin made of rounded logs
In our specific case, a team of craftsmen estimates their work at 5,000 rubles per cubic meter of processed wood. Log buildings from the mechanized woodworking workshop will cost the buyer 5500 rubles per cubic meter plus free shipping within a radius of 50 km from the workshop.

The team of craftsmen consists of 8 people: 2 cutters clean the log from bark, 2 planers cylinder the log with electric planers, 2 cups cut down the cups, 2 auxiliary workers in the hold. Such a team adds an average of 2-4 logs to the blockhouse per work shift. A blockhouse of 12 crowns for a five-wall bath will be ready no earlier than a month.

In a mechanized workshop, a team of 4 people will assemble such a blockhouse in less than a week.

Whether your lost time is worth an illusory gain of 5% of the final cost - you decide for yourself.

In traditional felling, manually adjusting each log will ultimately result in a warmer log.

Perhaps this position is true, but only in the case when a house or a bathhouse is being cut down for themselves. A team of custom-made craftsmen is forced to use every log that has been prepared, as a result, crooked, inconsistency, and other defective logs fall into the frame.

A curved log laid in a frame leads to deformation of the entire wall, in addition, its behavior in the future, when dried logs lose 5-8% in diameter, is absolutely unpredictable: huge cracks can form, an initially curved log is likely to bend even more strongly and deforms the entire frame.

The inconsistency does not allow you to accurately and equally cut grooves and cups. The ideal cup is cut into half the diameter of the log to be laid. And what kind of ideal cup can we talk about if a log with a diameter of 40 cm is placed on a log with a diameter of 20 centimeters? Indeed, in this case, the "ideal cup" will simply cut the lower crown in half.

And in general, what kind of accuracy are we talking about, if you can easily stick your finger into the holes between the crowns? How much would a happy developer who bought such a cheap traditional log house, did not push the insulation there - all the same, the wind will walk through the walls of such a log house.

In the workshop of mechanized processing, the listed problems simply do not arise:

There is no confusion, because logs are initially sorted by diameter, in the ordered blockhouse of 28 cm logs exactly 28 cm billets are placed - loading a forty-centimeter log into the machine to get a 28-centimeter billet is not profitable for the manufacturer himself. Curved logs are initially rejected - they simply cannot be rounded: beating of such a workpiece will break the machine. The grooves between the grooves are also selected on the machine, their depth is calculated based on the diameter of the logs. Therefore, there are simply no hesitations in this parameter in the log cabins made of rounded logs. And if there is, this marriage is clearly evident even to an inexperienced buyer.

Features in the use of a log house during construction.

It is customary to assemble a log house from winter cutting logs that have not been dried. In the process of wood drying, the log loses 5-5% of its diameter. Uneven drying results in radial cracks, often splitting the log in half. Classical technology in no way protects the log house from such destruction.

The figure shows how radial cracks from uneven wood shrinkage appear on the logs of the assembled frame already during the control assembly.

To protect the log from radial splitting from uneven shrinkage, a special compensation groove is cut in the rounded logs. Cut it from the side of the log opposite the cup to the depth of the radius.

The expansion groove should in no case be visible from the street and in contact with the external environment - usually the groove surface is covered with jaws of the inter-crown groove.

Although the expansion groove cannot withstand the radial cracking of the logs, it reliably protects the log from splitting in half.

Another, most often recalled sin of log cabins made of rounded logs, is the destruction in the process of cylindering of a dense subcrustal layer resistant to rotting and infections with mold and fungus.

But, as already mentioned above, these accusations make sense only in relation to logs from young pines of small (up to 24..26 cm) diameter: logs of larger diameter are carefully sorted, besides, the resin content in them is more than enough to resist any infection ...

Moreover, the woodworking equipment of a modern mechanized workshop allows rounding logs "for carrots", i.e. maintain the taper of the original workpiece. This technological complication satisfies the needs of the most fastidious customer and allows the construction of log cabins of both small and very large diameters, guaranteeing their long service, high assembly quality that does not change over time, and protection of wood from disease-causing infections.

Grinding is a mandatory operation that is performed inside and outside the house after the end of the shrinkage processes occurring in wooden structure after construction. Grinding removes from logs various defects, removes blue, levels the surface. The sanded wood must be further processed in a short time, otherwise the surface will be covered with a dark bloom, which can only be removed by repeated sanding. After polishing, the log house inside the house is treated with special antiseptic preparations that perform protective functions and protect wood from adverse factors of natural and biological origin. From the article you will learn how to process the log house after grinding.

During sanding, residues of bark, knots and unevenness are removed from the logs, thus completely removing the outer layer of the wood. After the surface is sanded, the logs are left unprotected and, without proper treatment, are exposed to various adverse influences.

The exterior walls of the house are negatively affected external factors... As a result of high humidity, mold, fungi and microorganisms can appear on unprotected logs. Wood can turn yellow when exposed to ultraviolet radiation. When overheating or freezing of wood due to constant change temperature regime the surface may crack.

Internal walls wooden house are in more favorable conditions, but, nevertheless, also need protection. The fungus that causes the tree to turn blue can also settle on the surface of the logs due to a violation of the operating mode. It is especially important to protect wooden surfaces rooms where high humidity is constantly present: bathroom, bath, sauna.

Please note that the processing of the log house after grinding outside and inside the house must be carried out no later than seven days. Otherwise, a dark coating will reappear on the surface.

Means for protecting a wooden house

For protective treatment at home after grinding, several groups of drugs are used:

• antiseptics;
• fire retardants;
• complex compositions;
• bleaching agents.

Provide protection of wood from biological damage, which include mold, different kinds fungi, microorganisms and insects.

Antiseptics are presented in two forms:

1. Impregnation. They are characterized by high absorbency. They penetrate a few centimeters deep into the wood fibers, protecting the tree from biological damage, and also destroy the already appeared foci of mold, colonies of fungi and microorganisms.
2. Covering means. Create on the surface protective layer, which does not allow moisture to pass through the wood. These drugs are especially relevant for wet rooms.

According to the duration of action, antiseptics are divided into the following groups:

1. Easy to wash off. These products contain metal salts, which are quickly washed off under the influence of water and moisture. These drugs are best used to cover wooden house from the inside. However, these products are not suitable for baths, saunas and bathrooms.
2. Difficult to wash. These preparations contain natural and artificial oils and are resistant to moisture and other weather conditions. Therefore, if there is a question of how to cover the frame from the outside after grinding, then it is best to use hard-to-remove compounds for external processing.
3. Short-term action. Such antiseptic impregnation quickly absorbed into wood and well tolerated high humidity and high temperatures. They protect the tree not only from mold, but also from insects. Perfect for baths and saunas.

Antiseptics are glazing and covering. The first ones create a transparent layer that completely preserves the natural grain of the wood. The latter form a tinted finish with a matte or glossy sheen.

Wood is very susceptible to fire, it ignites very quickly and burns well. To protect a wooden house from fire, it is necessary to cover the log house special means - fire retardants. This group of drugs is designed to protect wood from fire.

Flame retardants prevent fire and allow the wood for a long time withstand exposure to open flames without igniting.

There are two types of formulations:

1. Products containing sodium salts. When exposed to fire on wood treated with such a composition, gases are released that prevent combustion.
2. Non-salt preparations. The flame is blocked by the foam that forms on the wood when exposed to fire.

Complex means

The drugs in this group are universal. They protect the wood from different types adverse effects. The products prevent the penetration of moisture, protect the surface from fungus, mold and insects, and also prevent ignition.

Blueing of logs is a very common occurrence. The blue stain is caused by a special fungus that settles in untreated wood. It is not always possible to get rid of blue spots with help.

No matter how well the wood is polished, the spores of the fungus still remain and, under favorable conditions, they will again multiply intensively. For the complete destruction of the fungus, wood is treated with special ones.

All bleaches are divided into two large groups:

1. Chlorine-containing compounds. Chlorine is the main active ingredient in them. It is better to treat the log house outside with chlorine-based products.
2. Chlorine-free products. Active substance they contain hydrogen peroxide, ammonia, alkali, oxalic acid. Chlorine-free preparations are suitable for treating timber inside the house.

The principle of action of all means is to oxidize the surface, which leads to discoloration of the pigment and the destruction of fungal spores.

Before processing log walls protective means must be removed from the surface with a vacuum cleaner all dust and shavings formed during grinding, and then wipe the wood with a rag.

Temperature environment during processing should be at least plus five degrees with a humidity of about 80%.

Impregnations are applied in the following sequence: antiseptic, bleaching agent, fire-fighting agent.

Antiseptic and fire retardant impregnation is applied in two layers. Each new layer is applied after the previous one has completely dried, after about 24 hours. After using the bleach, the surface is washed with water.

Nowadays, buildings made from logs processed on cylindering machines are very popular. But any master will say that wood is a very capricious material. It is afraid of water, but at the same time it is impossible to seal its pores and prevent "breathing".

Unpolished rounded logs

Wood is susceptible to the influence of fungus, mold, woodworms, belongs to the group of highly combustible materials, sometimes the logs of an already built log house can "twist", they bend, crack. We will tell you how to deal with these problems in this article.

What is a rounded log

There are 2 subspecies of rounded logs:

The downside is that under the influence of precipitation and sunlight, the log darkens over time, but not completely, but only a few centimeters deeper. They will serve at home or baths from such trunks for a long time.

Most often as source material conifers - pine, spruce, cedar are used for cylindering. A log that is ready for use is obtained after the following processing steps:

The resulting rounded log is used for the construction of low-rise houses, baths, cottages, verandas, bars and other buildings for commercial, economic and residential purposes.

Processing facilities

Various means for processing logs from rounded logs

The instructions for the formulations always indicate the period when the drug can and cannot be used.

So, the processing of rounded logs with transport antiseptics begins immediately after the completion of the processes of profiling and facing. The application of the rest of the compositions - only after the assembly of the log house into a single structure and the sealing of the seams.

Steps for processing and applying protective equipment

Any means of protection are applied to wood with a moisture content of no more than 25%. The level is measured with a special device - a moisture meter (contact or non-contact).

To process a log house made of rounded logs, the following tools and units are required:

Grinding is done using a special attachment

All this will come in handy for DIY home processing. And in production conditions, another method is used - autoclaving. With the help of a special autoclave apparatus, the logs are treated with antiseptic and fire retardant compounds. For a log house from such blanks, mold and open fire will not be terrible for more than 10 years.

The inconvenience of this method is that sometimes the logs need to be adjusted and cut off excess, cuts. In this case, the protected layer is removed, that is, the impregnation will need to be restored.

Before starting work, you need to prepare:

The total processing of a log house from a rounded log begins only after a complete drying cycle, that is, at least a year after the construction of a house for a temporary roof. This is due to the fact that excess moisture in the building material makes it difficult for the composition to penetrate, and the effectiveness of its application is minimized.

Important! While the tree is damp, the shrinkage of the house will occur constantly, cracks, dents, irregularities may appear on ideally even trunks, which subsequently need grinding and sealing with special sealants or compositions based on epoxy resin, acrylic, silicone.

Processed corner of a log house

Rounded log problems and how to deal with them

1. On the finished log house cracks appeared.

During the shrinkage of the log, cracks may appear on it. As a rule, craftsmen prefer not to touch them to the last, since it is through them that the greatest amount of moisture comes out. After general processing log house defects are filled with a mixture of sawdust + epoxy resin or special sealants (Perma-Chink, REMMERS Acryl-100).

Rounded log like construction material, has a lot of advantages, but it is not without some disadvantages. Knowing about them and understanding what kind of wood processing needs to be done, it is possible to achieve the fact that the log house can stand safe and sound for several hundred years.

Factors from which you need to protect the log

The natural origin of the log and the method of processing its surface formed the following disadvantages:

The chemical industry has already responded to all these challenges by developing special products for processing logs. By choosing the necessary moisture-proof, fire-retardant and bioprotective compounds and having maintained the algorithm for processing a log house or each log, all the above risks can be reduced to a minimum.

The use of universal means that can protect against several potential dangers at once is not encouraged by professionals. Like everything universal, such formulations have minimum performance indicators in solving each highly specialized task.

Rules for processing walls made of rounded logs with protective compounds

Before the protective agents are applied to the surface of the logs, it is necessary to wait until the natural moisture is completely removed from the wood. Dried wood better perceives protective natural or chemical agents, allowing you to achieve greater efficiency from their application.

If the house is newly assembled, then the surface of the walls does not need to be sanded before applying. protective equipment... If you have to process the walls that have already stood for some time, then it will be necessary to remove the roughness on the surface of the logs and traces of mold, rotting or dirt by grinding. Then the ends are treated with a steam-generating antiseptic and oil paint or slaked lime mixed with manganese solution.

Funds are applied to a rounded log in the following sequence:

1. Antiseptic.
2. Moisture-proof composition.
3. Fire retardant.

This sequence was not chosen by chance. Mold and moisture can come from the inside of the wood, therefore, the deepest possible impregnation with special means is needed to create a barrier. The fire most often starts from contact with the outer part of the log, so it is important to protect the surface here.

Other compounds that can be used to process log walls

Many experts in modern housing construction have doubts about decorating (and protecting) a rounded log with paint. It would be unwise to hide the natural beauty of wood texture under a plastic film.

Therefore, for those who want to keep the smoothness and perfection of the treated surface of the logs, varnishes or glazing compositions are intended. Varnish (especially if it is frost-resistant) can also be considered protection, because it is a barrier against ultraviolet radiation and pollution.

Sometimes, after treatment with an antiseptic, moisture protection and fire retardant, a layer of preservative is also applied. It is designed to prolong the duration of these protective measures for as long as possible.

The treated house will last for several centuries

If you want to live in a house that will retain its appearance and functionality for a long time, then you should contact the builders who handle the log properly. Eko-Tech digging pays serious attention to the issue of wall treatment with protective compounds.

When building a house from cylindering, all logs must pass necessary processing protective compounds.

It is troublesome to handle the logs yourself, besides, in addition to skills, you need special brushes, spatulas and spray guns and knowledge of the algorithm for applying funds. It would be wiser to order the construction of a house with the obligatory processing of logs.
