Mastic fits perfectly on any foundation (stone, brick, concrete), reliably adheres to it, filling all chips, joints, cracks. Work on warming and sealing with a warm seam begins with stripping of the seam. Further, the seam cavity is foamed with mounting foam, which allows you to fill even the most inconspicuous voids and provide reliable insulation. After that, “Vilaterm”, compressed to 30%, is installed in the seam, which completely clogs the seam. And already on top of “Vilaterm” a two-component polyurethane mastic is applied, and when sealing small narrow joints - silicone sealant.
