Application description

STIR THOROUGHLY BEFORE USE. After suitablesurface preparation, apply 1 coat of Dulux Trade Stain Block Primer to all bare or stained surfaces and allow to dry. Two coats will be necessary for difficult stains. When blocking stains caused by water or damp, make sure the original cause of the problem has been rectified. When Dulux Trade Stain Block Primer is applied initially, it will draw the stain into itself and then seal it – this is not a defect. Finish with an appropriate Dulux Trade paint system.
