What it is for, in the maker's words: “A premium plant-based interior wall and ceiling paint made from fully declared natural ingredients” (Edward Bulmer Natural Emulsion technical data sheet, read 12 October 2026).

The walls of a 3 × 4 m room, 2.4 m high, need 6.77 L: 1 × 5 L + 2 × 1 L to buy.

## Coverage

Edward Bulmer states 10 to 14 m² a litre. The maker's words: “Coverage: 10-14m² 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: 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, 10 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 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.

## Coats

Edward Bulmer gives 2 coats for Edward Bulmer Natural Emulsion, in these words: “however substrates vary and occasionally extra coats may be required”.

## Tin sizes

| Tin | One coat | 2 coats |

Arithmetic on the maker's figure: the litres in the tin times the coverage per litre, with nothing added for waste.
