Surfaces must be sound, clean, dry and free from all defective or poorly
adhering material, dirt, grease or wax. Remove all loose and defective paint or
powdery residues by thorough brushing and scraping, using a stiff fiber brush.
Where necessary, wash the surface to remove dirt, grease and powdery or
dusty residues. Rinse with clean water and allow to dry. Treat any areas
affected by mould, lichens, algae and moss with Dulux Professional Fungicidal
Wash. Repair any surface defects with an appropriate filler. Surfaces that
remain powdery, friable or chalky after thorough preparation should be sealed
with one coat of an appropriate Sealer (see below System Recommendation).
Where necessary, rub down and then wipe off with a damp, lint free cloth to
avoid dust. Do not paint if the wall is saturated with dampness. (Protimeter
reading higher than 16%). Allow excess moisture to evaporate.
