In case of major damages, deep inside the skim coat a resistant alkali glass fiber net with a weight of 155 g “ RETE 160-A PER CAPPOTTO" with overlap of at least 10 cm.

7. The finished plaster can than be be decorated with a sponge trowel and the micro-claddings such as: acrylic resins and water-based superwashable varnish INFINITY 406 QUARZ, qaurtz-based acrylic QUARZO COAT or, in alternative, water-resistant and breathable acryl-siloxanic SANOFINISH anti-mold and anti-algae, mould and algae-resistant masking matt filler SANOFILL, or siloxanic varnishes such as the breathable and waterproof SILOX FINISH, mineral varnish with potassium silicate SILK FINISH or MINERAL FINISH with modified potassium silicate.
