Surfaces must be sound, clean, dry and free from all defective or poorly adhering
material, dirt, grease or wax. Remove all loose or defective paint or powdery
residues by thorough brushing and scraping, using a stiff fiber brush and high
pressure water jet. Treat any areas affected mould, lichens, algae and moss with
Dulux Fungicidal Wash. Repair any surface defects with 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). Do not paint if the wall is saturated with dampness.
