Step 1
Step 1 Surface preparation: New plaster – let the plaster dry completely for at least 1 month, with moisture content below 14%, then clean off all grease and dust. Old plaster – scrub off all loose and deteriorated old paint (do not use a wire brush) and wash the surface clean. If there is mould or moss, scrub it off first, then apply a generous coat of Beger MouldFree M-001 mould and moss remover without rinsing. After cleaning, apply 1 coat of Beger Pro Quick Primer B-1900 multi-purpose plaster primer
