Johnstone's Trade paints: coverage and tin sizes
3 Johnstone's Trade paints are in the BuildBatch catalogue. Their stated coverage runs from 10 to 17 m² a litre. Every figure is Johnstone's Trade's own, read on its pages and data sheets, most recently on 30 September 2026; a maker's coverage is their best case, on a smooth sealed surface.
Each product's page quotes the maker's words, shows what one tin covers and works out the tins for five room sizes with the planner. Nothing is ranked or tested, and BuildBatch sells none of them.

“A 3 × 4 m room” is the tins at the maker's own coverage with 10% extra, worked out by the planner: for a wall paint the walls, 2.4 m high with a door and a window taken off; for a woodwork paint one face of the door, its architrave, the window's frame and board and the skirting. Where a maker gives no single number of coats, one coat and two are both given. A primer, undercoat or sealer has no room table. Each product's page has five room sizes.
How these pages are made
- All products: every maker in the catalogue.
- How we compare products: what “worked out” and “Ad” mean, and what a page never does.
- Paint coverage explained: what a figure per litre means, and why a maker's figure is their best case.
