Polycell Stain Stop has been specially formulated to cover stains and marks on walls and ceilings in just one coat. Polycell Stain Stop dries to a white finish ready to be over-decorated and is suitable for use over nicotine, pen, crayon, rust, soot and dry water stains, preventing the stain from showing through and spoiling the decoration.
If the surface has patches of penetrating damp, use Polycell Damp Seal which is also a one coat application prior to redecorating.
