Primer, undercoat and sealer: coverage and sizes by product

58 products from 12 makers are listed under primer, undercoat and sealer in the BuildBatch catalogue. Each figure is the maker's own, with its source.

Each product's page quotes the maker's words, shows what one pack covers and, for a paint, works out the tins for five room sizes with the planner. Nothing is ranked or tested, and BuildBatch sells none of them.
