## Coverage

- 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 approximately 17 square metres, depending on the nature and porosity of the surface”.
- 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.
