Armstead Trade gives no single number of coats for it: “Finishing: Apply 1 or 2 coats of Armstead Trade Contract Matt”.

What it is for, in the maker's words: “Suitable for all normal interior wall and ceiling surfaces” (Armstead Trade Contract 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 × 5 L) or 4.513 L in two (1 × 5 L).

## Coverage

Armstead Trade states up to 15 m² a litre. The maker's words: “A guide to the practical coverage which can be achieved under normal conditions is up to 15m²/litre”.
- 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.
- 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.
