Make sure all surfaces are completely clean & dry. Repair damaged or cracked walls with a filler & remove loose or flaking paint. Special care must be taken during sanding or stripping the surfaces which may be painted in past with lead containing paints. Gently stir the paint if the surface liquid is visible. Apply thin coats of paint by using a brush, roller or paint pad at an ambient temperature between 10 & 30°C. If the paint is drying too quickly dilute with a little clean water. More than one coat may be required. Full opacity will be achieved when the paint is completely dry but ensure good ventilation during application & drying
