Application: Brush only. For Health and Safety reasons related to all solvent-based paints, spray application is not recommended. STIR THOROUGHLY BEFORE USE. Surfaces must be clean, dry and free from all defective or poorly adhering material such as dirt, grease and wax. Thoroughly rub down previously painted surfaces. New or bare surfaces up to 90ºC should be primed with an appropriate Dulux Trade primer. Above that temperature, Dulux Trade Aluminium Paint should be applied direct to the clean, prepared surface. Finish with 1 or 2 coats of Dulux Trade Aluminium Paint.
