OptiSilan TiefGrund

Deep penetrating, hydrophobic silicone resin primer for outside and inside

Field of Application

Transparent silicone resin-based primer.

OptiSilan TiefGrund is especially deep penetrating and hydrophobic due to the particularly fine-particle polysiloxane-hydrosol binder.
Consolidating and egalising on coarsely porous, absorbent, slightly sanding renders, masonry and concrete surfaces, gypsum boards (GK boards), gypsum plasters, gypsum filler, and weakly bonded dispersion filler.

Subsequently coatable with dispersion, silicone resin, and polymer resin paints.
