To get the best results with Dulux Light & Space, make sure surfaces to be painted are sound, clean, dry (new surfaces particularly must be fully dry).
Remove all loose and defective paint. Special precautions should be taken during surface preparation of pre-1960s paint surfaces over wood and metal as they may contain harmful lead.
Where necessary, wash the surface to remove dirt, grease and powdery or dusty residues. Rinse with clean water and allow to dry. Seal surfaces that remain powdery after thorough preparation with an appropriate plaster sealer.
Where necessary, rub down and then wipe off with a damp, lint free cloth to avoid dust.
Any surface defects should be filled with the appropriate Polycell Trade Polyfilla.
