Wood products with painted surfaces can reduce the risk of forming and spreading microbial infection on their surfaces. This study aims to characterize surface moulds resistance of selected transparent wood coatings based on polyurethane resins, polyurethane-acrylate resins, and natural wax withoilapplied in one, two or three layers. The growth activity of moulds (GAM) on the surface coated with wax - oil and waterbornepolyurethane-acrylate coating was higher than mould growth on the surface with polyurethane coating. The mould growth was decreasing with increasing number of coats of polyurethane or waterborne polyurethane-acrylate coating.
