What it is for, in the maker's words: “A 2-in-1 water-based natural product for use on all types of fresh plaster, suitable for priming and undercoating prior to topcoats and as a mist coat on previously painted walls” (Edward Bulmer Ultimate 2-in-1 Primer technical data sheet, read 12 October 2026).

## Coverage

Edward Bulmer states 10 to 14 m² a litre. The maker's words: “Average 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 surfaces take more.
- A range, not one figure: Edward Bulmer gives a range. An estimate should use the lower figure, 10 m² a litre, so that the answer errs towards enough paint.
- Waste and touch-ups: The tin-by-tin figures add nothing for what stays in the tray and on the brush, or for touching up.

## Coats

Edward Bulmer gives 1 coat for Edward Bulmer Ultimate 2-in-1 Primer, in these words: “If the wall is of poor quality, requires substantial filling or is a difficult colour to cover, two coats may be required”.

## Tin sizes

|---|---|
| 2.5 L | 25 to 35 m² |

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