Macpherson gives no single number of coats for it: “Apply one or two coats as required”.

What it is for, in the maker's words: “Ideal for interior priming of softwoods, hardwoods, hardboards, cement, brickwork, roughcast etc. and as an interior undercoat for gloss finishes” (Macpherson Acrylic Primer Undercoat data sheet (dated January 2016), read 12 October 2026).

## Coverage

Macpherson states 12 to 14 m² a litre. The maker's words: “Spreading rate 12 - 14m² per litre depending on surface texture and porosity”.
- 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. Macpherson's own words: “Spreading rate 12 - 14m² per litre depending on surface texture and porosity”.
- A range, not one figure: Macpherson gives a range. An estimate should use the lower figure, 12 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.
