Polycell One Coat Damp Seal has been specially formulated to seal patches of penetrating damp on interior walls and ceilings in just one coat, preventing them from showing through and spoiling decorations. Polycell Damp Seal has a matt white finish that can be decorated if required.

HOW TO USE : 1) Allow new plaster to dry for at least 1 to 2 weeks before using this product. 2) Stir the product well. Do not thin. 3) Apply the product generously with a brush or roller to damp but not saturated surfaces working well over the affected area and a wide surrounding area, while avoiding runs. 4) Avoid splashing on polystyrene tiles or any plastic materials. 5) Allow to dry fully before overcoating (overnight). 6) Treated surfaces are now ready to decorate. 7) Drying of wall coverings, especially vinyl coverings may be slowed.
