Source: Dulux Trade, Dulux Trade High Gloss data sheet 403 (issued 08/25), read 11 October 2026.

Dulux Trade gives no single number of coats for it: “Apply 1 coat of the appropriate coloured Dulux Trade Undercoat, followed by 1 or 2 coats of Dulux Trade High Gloss”.

What it is for, in the maker's words: “Suitable for use on interior and exterior wood and metal surfaces” (Dulux Trade High Gloss data sheet 403 (issued 08/25), read 11 October 2026).

The woodwork of a 3 × 4 m room (one face of a door and its architrave, a window's frame and board, and the skirting: 3.73 m²) needs 0.228 L in one coat (1 × 1 L) or 0.456 L in two (1 × 1 L).

## Coverage

Dulux Trade states up to 18 m² a litre. The maker's words: “On smooth surfaces of average porosity, a guide to the practical coverage that can be achieved 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 wood takes more. Dulux Trade's own words: “On smooth surfaces of average porosity, a guide to the practical coverage that can be achieved is up to 18m² per litre”.
- 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 brush and for touching up: BuildBatch's generic example, not the maker's. The tin-by-tin figures add nothing.
- Doors, windows and skirting of another size: The table counts one door, one window and skirting 119 mm high with an architrave 69 mm wide, the planner's typical sizes. Panelled doors, deep skirting, more doors or a radiator take more: the planner counts your own.
