Key points
- Coverage assumed: putty 20 sq ft/kg, primer 120 sq ft/L, emulsion 150 sq ft/L per coat.
- Deducts door / window area from paintable surface.
Formula & how it works
Paintable = wall area − openings.
Emulsion litres = area × coats ÷ 150.
Worked example
- 1000 sq ft wall − 80 sq ft openings → 920 sq ft.
- Putty ≈ 46 kg, Primer ≈ 8 L, Emulsion (2 coats) ≈ 13 L.
Expert tips & mistakes to avoid
- Always add a 5–7% wastage buffer — mid-slab shortages cost more than the buffer bags.
- For engineered members (RCC columns/beams), follow the structural drawing over any calculator.
- Order cement in tranches — bags older than 90 days lose strength.
- Confirm the current market rate on WhatsApp before finalising the budget — prices printed here are indicative only.
Frequently asked questions
Do I always need putty?
+
For a smooth finish on plaster, yes — putty fills pinholes and gives even paint absorption.
