• Do not abrade Dulux Trade Stain Block Primer before recoating. Special precautions should be taken during surface preparation of pre-1960s paint surfaces over wood and metal as they may contain harmful lead.

Always follow the manufacturers instructions found on the tin, it is recommended that a small test area is applied before painting the entire surface to ensure compatibility.

• Stir thoroughly before use.
• After surface application, apply 1 coat of Dulux Trade Stain Block Primer to all bare or stained surfaces and allow to dry. For difficult stains, 2 coats will be required.
• When blocking stains caused by water or damp, make sure the original cause of the problem has been rectified before applying this primer.
