Tikkurila gives no single number of coats for it in the document read for this page.

What it is for, in the maker's words: “Interior walls and ceilings in spaces in which high wash and wear resistance is required, such as kitchens, halls or stairwells” (Tikkurila Luja 20 product data sheet, read 12 October 2026).

The walls of a 3 × 4 m room, 2.4 m high, need 4.231 L in one coat (2 × 2.7 L) or 8.462 L in two (1 × 9 L).

## Coverage

Tikkurila states 8 to 12 m² a litre. The maker's words: “Theoretical coverage: 8-12 m²/l”.
- 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.
- A range, not one figure: Tikkurila gives a range. The room table uses the lower figure, 8 m² a litre, so that the answer errs towards enough paint.
- 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.
