Step 1
Step 1 Surface preparation: New plaster – let it dry completely for at least 1 month, or until moisture content is below 14%. Old surfaces in good condition* – clean the surface so it is free of dust, plaster residue, grease and all dirt. Old plaster – scrub off all deteriorated old paint with a plastic brush. If the surface has mould and moss, remove it with Beger MouldFree M-001 mould and moss remover. If the surface has hairline cracks of 0.3-1 mm, fill them with Beger Acrylic Filler F-200. If the surface has cracks of 1-10 mm, fill them with Beger Acrylic Sealant F-001
