Surface Preparation Guide for Kitchens & Bathrooms
1. New Work:
1.1 Cement plaster, concrete, unglazed brickwork, fibre-cement, ceiling boards: Remove any loose particles and laitance by most suitable means. Prime with PLASCON PLASTER PRIMER.
1.2 Gypsum plaster (e.g. Rhinolite, Cretestone): Prime with PLASCON PLASTER PRIMER.
N.B. Soft, underbound, friable and highly porous surfaces must be restored to a sound condition before painting with PLASCON PLASTER PRIMER.
N.B. If a gypsum plaster has been used as the joint skimming filler on gypsum board or dry wall partitioning, then these areas must be sealed with PLASCON PLASTER PRIMER.
1.3 Wood: Sand smooth with 150 grit paper working in the direction of the grain. Dust off. Seal knots and resinous areas with PLASCON KNOT SEAL. Prime entire surface with PLASCON WOOD PRIMER.
1.4 Mild steel: Degrease with PLASCON AQUASOLV DEGREASER. Rinse thoroughly with water. Remove any rust by coarse sanding, mechanical grinding, etc. or PLASCON RUST REMOVER. Prime general surfaces the same day with METALCARE MILD STEEL PRIMER or PLASCOSAFE 18 PRIMER – use ZINC PHOSPHATE PRIMER RED OXIDE for structural steelwork.
1.5 Galvanised steel: Clean with METALCARE GALVANISED IRON CLEANER to achieve a water break-free surface. Rinse thoroughly with water. Prime the same day with METALCARE GALVANISED IRON PRIMER.
