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.

“Armstead Trade Undercoat is a professional quality, solvent-based undercoat suitable for use on all types of interior and exterior wood, metal and suitably primed masonry surfaces”
