Coverage

Exterior paint: 60-80 sq ft/litre। 2000 sq ft exterior × 2 coats / 70 = ~57 litres। Apex Ultima (Asian Paints): ₹350-500/L। WeatherCoat (Berger): ₹300-450/L। Weather-proof paint essential in Indian monsoon।

Monsoon

Exterior painting: October-March best (dry season)। Monsoon में paint न करें — adhesion poor। Anti-fungal/anti-algae properties ज़रूरी in humid areas।

⚡ CalcWolf Insight

The north side of a house typically needs repainting sooner due to more moisture retention and less UV exposure (which paradoxically helps cure and harden paint). Plan to touch up the north side 1-2 years before doing a full repaint.
