For best results, ensure surfaces to be painted are sound, clean, dry and free from dirt, dust or any other surface contaminants.

1. Remove all loose and defective paint with a paint scraper by sanding or with a paint stripper
2. Special precautions should be taken during surface preparation of pre-1960s paint surfaces as they may contain harmful lead
3. Where necessary, wash the surface to remove dirt, grease and powdery or dusty residues
4. Rinse with clean water and allow to dry
5. Any surface defects should be filled with an appropriate filler
6. If required, rub down surfaces and then wipe off with a damp, lint-free cloth to remove dust
7. Seal all surfaces that remain powdery after thorough preparation with an appropriate plaster sealer, or use Dulux Trade Stain Block Primer, which will also seal in any stains

Always do a test area before starting any project to assess product suitability and final finish. Follow the manufacturer's instructions on the tin at all times.

For best colour consistency, purchase sufficient paint for each project including enough for touch-in at a later time.

Do not use below 8°C or in areas of high humidity or condensation.
