If it is necessary to waterproof in a wooden house-the bitumen-polymer mastic containing very little moisture is perfect here. In addition, residual moisture is absorbed by the activator. This is an absorbing powder, which must be added to the mastic before use. As a rule, in wooden houses, the processing area is relatively small and the processing itself is not difficult, so it can be done alone, without buying additional materials, expensive equipment and hiring workers.
