Master Base Primer, Extra White is a thick, water-based wood primer that is ideal for areas where an intensive light look is required. The primer seals the wood and minimises the tannic acid penetration and side-bonding. It is only suitable for untreated or sanded surfaces of light woods and works as a powerful basic lacquer before treatment with other water-based WOCA floor lacquers.
Final sanding must be done with fine sandpaper (grit 120). Vacuum carefully afterwards. The surface must be free of dirt, grease, wax and dust. The primer must be room temperature before use.
Apply the primer undiluted with brush or roller, following the wood along its length, and allow the surface to dry. Please note: For a more intensive light appearance, apply another coat of primer. Sanding must be done after the first coat with 180–220 grit sandpaper (a treatment with a white-pigmented material generally requires more even sanding to prevent the pigments from sticking in the sanding grooves).
When the wanted appearance has been achieved, apply 1-2 topcoats with one of the WOCA floor lacquers. Always apply a minimum of three coats (primer and lacquer) for ideal protection.
