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.

“It can be applied on interior or exterior wood and metal surfaces”
