SURFACE PREPARATION
NEW AND UNPAINTED: Ensure that surfaces are dry and cleaned free of all dirt, dust, grease, oil, wax, form oils, parting compounds, fungal and algal growths and other debris and contaminants. Rub down with rubbing stone/ brick to remove all loosely adhering particles.
NEW SURFACES: Ensure that surfaces have thoroughly dried out, allowing cement rendered surfaces and cement – mortar pointing to cure for 4-6 weeks and poured concrete for 6-8 weeks The surfaces must be dry and cleaned free of all dirt, dust, grease, oil, wax, form oils, pointing compounds, fungal and algal growth, and other debris and contaminants. Fill any surface defects (holes, cracks, crevices etc.) with appropriate masonry / wood filler. Rub down with rubbing stone/ brick to remove all loose particles.
PREVIOUSLY PAINTED: Remove all loose, flaking, peeling and semi-adherent paint, sanding to a featheredge where necessary, and remove all contaminants, to obtain a clean, firm, sound surface. Fill surface defects as for new surface. Rub down smooth glossy surfaces.
Treatment of Fungus and Algae Infected Areas: Clean infected areas with a solution of 1 litre household bleach, 1 tablespoon household detergent and 3 litres of water. Leave on for 1 hour, and then rinse off thoroughly. Repeat if necessary. For cleaning painted surfaces use a sponge, and for unpainted masonry use a stiff brush.
Treatment of Efflorescence: This problem appears as white spots or apparent “bleaching” of unpainted or previously painted masonry surfaces. It is caused by drying-out of new plaster/rendering, rising dampness, or water leaks into the walls, which must be rectified before proceeding. Loose efflorescence should be removed by vigorous brushing with a coarse sacking or dry brush, followed by light rubbing with a damp cloth. This should be repeated at intervals of 3-4 days, until it is evident that the efflorescence has ceased. Finally apply one (1) coat Penta Latex Sealer. If efflorescence is of the smooth, hard type (lime- bloom) it should be lightly abraded to ensure good adhesion.
ALUMINIUM: Clean and etch-prime with Penta Etch Primer.
