Use actual label coverage. Excludes primer; surface and application affect consumption.

Formula and method

Liters = (total area − openings) × coats ÷ coverage per liter × (1 + waste/100). Round can count up.

Worked example

60 m² wall minus 5 m² openings, 2 coats, 10 m²/liter coverage and 10% waste needs 12.1 liters, or two 9-liter cans.

Frequently asked question

Is primer included?

Primer is excluded. Calculate it separately using its coverage. Rough or absorbent surfaces may require more paint.
