Dulux Undercoat Pure Brilliant White is a solvent-based formulation, the ideal partner for Dulux High Gloss. It provides excellent opacity and contributes to exceptional gloss retention. It has superb hiding power, good ‘cling’ to sharp edges and excellent leveling properties. Newly painted doors and windows should not be closed and radiators should not be heated until paint is fully dry. For best results, scrape off excess paint from the brush and clean with Polycell Brush Cleaner. When using more than one can, make sure batch numbers are the same and mix in a large container to guarantee uniformity.
