Application advice

Prepare your surfaces carefully before application: they must be clean, dry, sound and free of dust, dirt, loose material, soot, grease, oil, wax, mould, wallpaper or adhesive. Cover Stain is applied by brush, roller or spray gun depending on the surface to be treated. Dilute if necessary with an appropriate thinner according to the chosen application method.

Ensure good ventilation of rooms during application and drying, as this is a solvent-based product. Tools are easily cleaned with thinner immediately after use. Wait at least 2 hours before applying your topcoat, and up to 4 to 7 days for complete film hardening. Note that this primer is not intended for floors, decking, roofs or surfaces subject to immersion or prolonged contact with water.
