What it is for, in the maker's words: “Ideal for use on plaster that is still drying out, but also suitable for use on all normal interior wall and ceiling surfaces” (Dulux Trade Supermatt data sheet 410 (issued 09/25), read 11 October 2026).

The walls of a 3 × 4 m room, 2.4 m high, need 3.761 L: 1 × 5 L to buy. At 10 m² a litre, BuildBatch's generic example for a wall that is not the maker's best case, the same room needs 6.77 L: 1 × 10 L.

## Coverage

Dulux Trade states up to 18 m² a litre. The maker's words: “A guide to the coverage which can be achieved under normal conditions is up to 18m² per 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: Dulux Trade says: “however for significant colour change additional coats maybe required”. 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.
