What to close the cracks in the log

With all the advantages of wood, natural disadvantages are characterized - drying, shrinkage and tapping, so defects arise on the log on the log. Most of them can be eliminated by their own hands.

Transverse splits appear due to loading or overload, such details are not repaired, but only replaced. Small longitudinal cracks are eliminated by special sealantFor wider (from 5 mm) there is a technology that includes insulation and hermetic sealing of seams.

For repair, you will need:

The filler is the thermal insulation harness "EnergoFlex" (replaced by packles, felt or just foam);
Sealant - Neomid or Evrotex;
Knife, scraper;
Rubber spatula;
Manual sprinkler for water.

Pre-internal cavities are processed by the antiseptic composition, then the walls are dried. All further work is made on dry brings.

The order of sealing cracks in the log:

Splits are cleaned with chips, sawdust and loose wood.
Filler is laid in crack - about half of its depth;
Next, the remaining cavity is filled with sealant;
With the help of a spatula, the edges are smoothed so that a smooth surface has come out - it is easier to do if splashing on a sealant from the sprayer;
The surplus is removed with a rap and the time is withstanding to completely dry the seam.

The slots between the logs are sealed by dry filling - caulking. A package is used as a placeholder, felt or jute. First, the material is shred into the joint with a wooden blade, then tapping in it with a color, is finally compacted until it becomes spring. The protruding residues are cut off with a knife or a grinder with a mounted petal circle.

It is convenient to use ready-made sealing compositions, but they all possess one disadvantage: after a few years, wood will dry and crack will appear again. This minus is deprived of a permanent moss, which is soaked with water before use 30 minutes, and during drying it increases by 20%, thereby thoroughly blocking the gaps.

Sealing cracks with natural moss or packles is suitable for outdoor and inland walls, harmless to wood and serves almost as much as himself log. The order of work on cacapatka can be viewed in the video clip.
