Before you start working with film material, it is necessary to weld or gluing the strips. As a rule, they mainly use PVC or polyethylene film, which differ in convenient transportation. The welding process can be carried out by a special gun-grip. If there are surfaces horizontally directed, then isolation should be carried out with some subtleties. First of all, the limiting evenness of the base is ensured, after which it is covered with bitumen, and later the film is placed on this. As for insulating canvases, it is allowed to use them with several layers, but, importantly, they should be bent and carefully smeared mastic. If you lay dry, it is important to correctly orient the correct overlap. The joints should be cooked with hot air. You also need to paint the walls in the apartment to do it better with it with your own hands.
With tight laying waterproofing on a concrete base, it is important to use mastic only a polymer-bitumen. It is heated to eighty degrees. It is better to apply glue with a roller. After waiting for a while, to evaporate the solvent, they proceed to rolling out the paintings and smoothing them.
