## Coverage

Leyland Trade states about 8 to 12 m² a litre. The maker's words: “1 litre will cover between approximately 8 and 12 square metres depending on the nature and porosity of the surface being painted”.
- 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. Leyland Trade's own words: “1 litre will cover between approximately 8 and 12 square metres depending on the nature and porosity of the surface being painted”.
- A range, not one figure: Leyland Trade gives a range. An estimate should use the lower figure, 8 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.
