Surface Coating System

Apply one coat of undiluted AmphiSilan Tiefgrund on normally absorbent substrates. On highly absorbent substrates apply also undiluted, but liberally, saturating the full surface.
The priming coat must not form a continuous, glossy film on the surface.
When adding/mixing max. 10 % of AmphiSilan Tiefgrund into ThermoSan, an additional priming coat can be omitted in most cases. Follow Technical Information No. 156.

Consumption

Approx. 150 - 250 ml/m2 depending on substrate requirements.
Determine the exact amount of material required by coating a test area on site.
