Use of a sealing coating for improving adhesion of a Michael Addition curing coating to a wood substrate comprising acidic substances,

• wherein the sealing coating is formed by a sealing agent comprising one or more chosen from an aqueous latex of polyurethane acrylics polymer, an aqueous latex of carboxyl functional self-crosslinkable acrylics polymer, an aqueous latex of cationic acrylics polymer, an aqueous latex of polyvinyl acetate and a two-component polyurethane coating system;
• and
• wherein the Michael Addition curing coating is formed from a two-component curable coating composition comprising:
• A) a film-forming resin composition, comprising a) a first reactive component having at least two acid proton C—H in activated methylene or methine, b) a second component having at least two active unsaturated C═C group, and c) optionally additional additives comprising one or more chosen from fillers, solvents, surface active additives, defoamers, dispersants, UV absorbers, open-time extenders, preservatives and fungicides;
• and
• B) a catalyst for catalyzing the Michael Addition reaction of the film-forming resin composition.
