Tips & Advice

Surface Preparation

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 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). Do not paint if the wall is saturated with dampness. (Protimeter reading higher than 16%). Allow excess moisture to evaporate.

Application Tools

By roller, brush or conventional/airless spray.


Ready for use or thin 5 – 10% with clean water
