proPERLA® Primer is a special water-based primer for proPERLA® Facade Coatings with solidifying effect and high penetration depth. It is diffusively and adherent and only suitable for porous surfaces.
Complete facade cleaning with high pressure is necessary to eliminate organic components such as mould, algae or moss, stains, etc.
150-200 ml per m2, depending on porosity.
3 – 5 hours at 20° C and 65% RH. Lower temperatures and higher humidity extend the drying time accordingly.
10 Litre Pots (40 Pots per pallet)
Use an airless sprayer or sprayer. A minimum temperature of 5 °C is required. The primer must be completely absorbed. Ensure that after drying no glossy film exists. Low absorbent surfaces such as clay or fiber-cement panels need to be primed thinly. For very porous substrates proPERLA® Primer may be diluted 1: 1 with water. proPERLA® Primer is not suitable for non-porous substrates.
Note: Components that don’t need to be treated have to be protected from splashes – eg by covering – as dried proPERLA® Primer is very difficult to remove. Once the primer is dry, proPERLA® Facade Coating can be applied.
