Prepare
Remove loose or flaking material. Make sure the surface is clean (no dirt or grease) and dry. If new, bare and absorbent surface, seal with this product, thinned 10% with water, or if very porous, use Dulux Sealer for Plaster. If the wall is damaged, repair using the appropriate Polycell product.
Apply
Apply 2 coats with a brush or roller, leave 2-4 hours between coats. Do not apply in very damp or humid conditions or in extreme temperatures. TIP: if the colour change is strong, more coats may be required.
