Dulux gives no single number of coats for it: “Apply 1 coat of Dulux Professional Undercoat with a brush, followed by 1 or 2 coats of Dulux Professional Liquid Gloss”.

What it is for, in the maker's words: “It can be applied on interior wood and metal surfaces to give long-lasting protection” (Dulux Professional Liquid Gloss product page, 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 0.256 L in one coat (1 × 750 ml) or 0.513 L in two (1 × 750 ml).

## Coverage

Dulux states up to 16 m² a litre. The maker's words: “Up to 16m2/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.
- 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.
