What it is for

In the maker's own words. A primer, undercoat or sealer goes where the surface needs it, which may be a whole wall of new plaster or drywall or only bare or stained patches, so this page gives no number of tins for a room: measure what you are priming and use the figures below. The planner counts the paint over it, not the primer.

“Dulux Stain Block covers all kinds of common household stains and prevents the appearance of the stain on the surface”
