Tips & Advice

Surface Preparation

Suitable for priming cleaned clay, cement, concrete and terracotta tiles. New glazed tiles are required to be sanded down to make keys for adhesion. It can be used on old glazed tiles which have lost the glazed film. Weathered roof tiles are often friable and chalky even after cleaning by scrubbing or high pressure water jetting; unless properly cleaned before painting, the paint may flake on aging. 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 to use. Dilute up to 10% with potable water when necessary if application by brush or roller. For conventional spray application, thin up to 10 - 20%.

Note: Excessive dilution from that recommended will result in low coverage and may impact application properties and colour.
