The use of wood in buildings entails the implementation of rules to preserve the integrity of wood and improve its properties. For this, boards and wooden beams must be subjected to processing, painting and protection using special means. However, it is especially necessary to be careful when processing the ends and sections of logs, since this place is the most accessible for moisture penetration, which contributes to decay and decay of wooden products.
Not timely processing and painting of a wooden log house will lead to the appearance of deep cracks on the logs, as well as to a violation of the hardness of the wood. The ends allow the trees to quickly get rid of moisture that moves along the trunk along the wood fibers, evaporation through the side walls of the tree takes much longer, this uneven evaporation of the liquid leads to tension inside the log, cracks and to the appearance of fungus in the places of the log house.

It is necessary to process the slice immediately after the construction of the structure. If log trunks retain their natural functions and require at least a year for complete drying before processing, then the ends need immediate protection.
When impregnating logs, attention should be paid to the procedure for this procedure, and also take into account that a wooden beam should be able to breathe and evaporate moisture. Therefore, if you are working on the external parts of a wooden structure, then you can not carry out internal processing of the premises.
End protection is carried out in several stages and requires special tools:
- Before using the material to cover the beam, it is necessary to give it a smooth, even surface using a chainsaw or other tools;
- The next step is the grinding of the wooden cut. By polishing the beam, it is cleaned of bumps, stains, mold, giving the tree a flat surface. Darkened wood is removed before painting.
- Application of material or impregnation to protect the end face.
Means for impregnation
The use of impregnation for the ends can be carried out in various compositions that protect wood and repel excessive absorption of moisture:
- End protection with impregnants and septic tanks. These substances protect wood from mold, fungus and insects. Impregnants and septic substances are applied with a brush in two or three layers to the log, with interruptions of 12 hours to dry.
- The sealant has a water-repellent property, preserving the logs from rotting and forming a protective film. It is recommended to apply this material in two layers.
- Engine oil is the most economical option for processing a wooden butt. Use the product twice, after 10-12 hours.
- Paints diluted with a solvent will seal the beam from the penetration of insects or moisture, as well as prevent the appearance of fungus.
- The use of lime is the most ancient and well-known method of processing wood, which protects wood from moisture and insects.
Processing Rules
End processing should be performed immediately after stacking the logs. The grinding process before applying a protective or paint material must be carried out in dry weather, which will allow the timber to dry faster, and eliminate the possibility of excessive moisture and the appearance of villi on the logs, which does not allow to smooth the surface of the log house, and qualitatively apply the material.
Since the end of the log is a weak spot in the tree that easily absorbs and absorbs liquid, the timber should be processed in several layers. This will protect the tree from excessive moisture and insects.
Using protective materials, it is necessary to pay attention to their composition, quantity and properties. When machining the ends, the amount of material needed will increase compared to machining walls or other parts.
The protection of the bars is carried out not only through two or three layers of material or paint, but also by combining these means, applying them alternately. For maximum protection and processing of the ends, it is recommended to apply a protective composition of antiseptic action, and after drying repeat the procedure using sealant, it will increase the moisture resistance and protective properties of the tree.
Processing the ends of the logs is the most important stage in the construction of wooden structures and buildings, which will allow the wood to remain in its natural solid state and prevent rotting and damage to the fibers. This stage requires certain knowledge and skills, however, it is possible to carry out the processing of wooden ends without the use of professional help, having studied the basic rules, conditions for applying protective equipment, their properties and interactions.
