Formula
Coverage per coat (m²/L): Emulsion (interior) → 12 m²/L Emulsion (exterior) → 10 m²/L Distemper → 9 m²/L Enamel → 11 m²/L Total litres = (area × coats) / coverage_per_coat Add 10% wastage for brush/roller loss

Practical Tips
- •Always apply a coat of wall primer before emulsion — it reduces paint consumption by up to 15% and improves adhesion.
- •For exterior walls, use weather-shield or elastomeric paint; regular interior emulsion delaminates within 1 monsoon.
- •Sand the surface to smooth Ra < 10 µm before painting — improves coverage and reduces litres required.
