The walls of a 3 × 4 m room, 2.4 m high, need 4.835 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

Macpherson states up to 14 to 16 m² a litre. The maker's words: “Up to 14m2 - 16m2/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: Macpherson gives a range. The room table uses the lower figure, 14 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

Macpherson gives 2 coats for Macpherson Eclipse Emulsion, in these words: “Apply two coats as required”.

## Tin sizes

| Tin | One coat | 2 coats |
|---|---|---|
| 5 L | up to 70 to 80 m² | up to 35 to 40 m² |
| 10 L | up to 140 to 160 m² | up to 70 to 80 m² |

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