Paraffin for impregnation, boiling hives, Dnipropetrovsk region.

Paraffin for impregnation of beehives, packed in bags of 25 kg.
A thin film of paraffin is formed on the hive, which has hydrophobic properties. Boil in boiling paraffin for about 10 to 30 minutes (until the bubbles of boiling water stop appearing) so that the paraffin gets into the pores of the wood.(//tractor-service.com)
When wood is heated, internal moisture evaporates and air expands in the pores of the wood, the paraffin seems to boil. After pulling from the trough, the paraffin is absorbed from the surface into the wood. When operatinghives practically do not swell, the shell does not eat, the wood does not rot.
In winter, good ventilation is needed in paraffined beehives, otherwise there is a lot of dampness (the tree becomes almost air and moisture impervious)
In this way, you can protect the hive without painting.
