Estimates the amount of paint needed to cover walls and ceilings.
The paint calculator estimates how many litres of paint you need to cover walls or a ceiling, based on net area, product coverage rate, and number of coats.
Paint needed (L) = (Net area × Coats) / Coverage (m²/L) Round up to nearest can size
Net wall area 46 m², 2 coats, coverage 10 m²/L. Paint = (46 × 2) / 10 = 9.2 L. Buy three 3.5 L cans (10.5 L).
