2. A light-coloured stripe gradually forms on the surface of the facade due to the deposited salt crystals. In this area (H-h), the moisture content in the plaster mortar varies depending on the season. The moisture that has risen in the wall evaporates on the surface, leaving the salt crystals behind.

11. Apply the damp-proof basecoat render weber.san 162 WTA or the damp-proof render weber.san 161 full-surface on top of weber.san 160 WTA in a thickness of 20-30 mm. Whenever a damp-proof plaster in a thickness over 30 mm is required, apply the damp-proof basecoat render weber.san 163 WTA beforehand.
