Description
Wall coating based on modified potassium silicate, inorganic pigments and mineral fillers that react with the substrate, consolidating it. Featuring high breathability, it preserves the substrate from mold formation by virtue of the high alkalinity of the silicate.
Use
Can be applied to old and new plasters based on hydraulic binders as a filler and as a substrate uniforming agent. Can be used on old paints, both organic and mineral, as long as they are absorbent and cohesive.

Surface preparation
Plasters:
Ensure that the substrate has passed a curing time of 28 days and that its moisture content is less than 10%. Remove by washing and brushing any efflorescence. Old paintwork should be totally removed. Any leveling or redoing should be done with mortars compatible with potassium silicate (pre-mixed plasters, lime, cement).

Old paintwork should be totally removed. Any leveling or resurfacing should be done with mortars compatible with potassium silicate (pre-mixed plasters, lime, cement).
Old surfaces:
Remove dust and old paint that is coming off, widen any cracks and fill them with filler. Completely remove old lime or tempera paints.
If mold is present, provide an appropriate anti-mold treatment.
