What it is for, in the maker's words: “AllCoat® Commercial (water-based) is a multi-surface primer, sealer and finish for interior applications” (Zinsser AllCoat Commercial product page, read 12 October 2026).

The walls of a 3 × 4 m room, 2.4 m high, need 3.385 L: 1 × 10 L to buy.

## Coverage

Zinsser states 10 m² a litre. The maker's words: “Coverage: 10m² per 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.
- 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

Zinsser gives 1 coat for Zinsser AllCoat Commercial, in these words: “One coat is all that is needed to cover and seal most surfaces”.

## Tin sizes

| Tin | One coat |

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