Johnstone's Trade gives no single number of coats for it in the document read for this page.

What it is for, in the maker's words: “Suitable for use on wallboards, concrete, brickwork and blockwork in internal situations” (Johnstone's Trade Cleanable Matt data sheet, read 11 October 2026).

The walls of a 3 × 4 m room, 2.4 m high, need 2.257 L in one coat (1 × 2.5 L) or 4.513 L in two (1 × 5 L).

## Coverage

Johnstone's Trade states up to 15 m² a litre. The maker's words: “Johnstone’s Trade Cleanable Matt will cover up to 15 square metres per litre depending on the nature and porosity of the surface being painted”.
- Bare, rough or absorbent surfaces: A maker's coverage is their best case, on a smooth sealed surface: bare, rough or absorbent walls take more. Johnstone's Trade's own words: “Johnstone’s Trade Cleanable Matt will cover up to 15 square metres per litre depending on the nature and porosity of the surface being painted”.
- A strong change of colour: Going from a dark colour to a light one, or the other way, can take another coat, and each extra coat is the paint of one coat again.
- Waste and touch-ups: The room table adds 10% for what stays in the tray and on the roller and for touching up: BuildBatch's generic example, not the maker's. The tin-by-tin figures add nothing.
- The ceiling and the woodwork: Neither is in these figures. Each is a separate paint and a separate line on a list.
