Master Base Primer, Natural is a thick, water-based, quick-drying and sandable wood primer. The primer seals the wood and minimises tannic acid penetration and side-bonding. It is only suitable for untreated or sanded surfaces 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.
Apply a layer of topcoat with one of the WOCA floor lacquers. Leave the surface to dry until next day.
Sand the surface with 120–180 grit sandpaper and vacuum clean the surface thoroughly.
Apply another 1-2 topcoats.
