Edward Bulmer Water-Based Eggshell covers 11 to 13 m² a litre, by Edward Bulmer's own figures.
Source: Edward Bulmer, Edward Bulmer Water-Based Eggshell technical data sheet, read 12 October 2026.

Edward Bulmer gives no single number of coats for it: “Apply 2–3 coats evenly using a high-quality brush or fine-pored foam/short-pile roller”.

What it is for, in the maker's words: “A premium water-based satin finish suitable for interior and exterior woodwork and metalwork, including radiators” (Edward Bulmer Water-Based Eggshell technical data sheet, read 12 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 0.373 L in one coat (1 × 375 ml) or 0.746 L in two (2 × 375 ml).

## Coverage

Edward Bulmer states 11 to 13 m² a litre. The maker's words: “Coverage: 11-13m² 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.
- 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.
- A range, not one figure: Edward Bulmer gives a range. The room table uses the lower figure, 11 m² a litre, so that the answer errs towards enough paint.
- 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.
