Paint, Wall Putty & Primer Cost Calculator (2026 Per Sq.Ft BOQ)

Q: How much area does 1 bag (40 kg) of Birla White or JK Wall Putty cover in 2 coats?

On standard internal 12mm smooth cement plaster, 1 kg of white-cement wall putty covers 16 to 20 sq.ft in 2 coats (1.0mm–1.5mm total thickness). Therefore, a standard 40 kg bag covers approximately 680 to 750 sq.ft in 2 coats on fresh plaster, or 1,200 to 1,350 sq.ft in a single skim coat during repainting.

Q: How do I estimate total paintable wall + ceiling area from my house or office carpet area?

When exact wall elevation measurements are not yet available, civil estimators multiply the internal floor carpet area by 3.0× to 3.5× (average 3.2× after deducting 15% for doors and windows) to obtain the combined wall + ceiling paintable surface area.

Q: Why does new paint peel, blister, or show chalky patches within 6 months?

Paint failure on new masonry occurs when putty or primer is applied over uncured green plaster with internal moisture above 15%, or when alkali-resistant primer is skipped between white putty and topcoat emulsion. Enforcing a mandatory moisture-meter check (<12% WME) and applying 1 full coat of alkali-resistant primer after putty sanding prevents efflorescence and peeling.

Q: How many litres of primer and emulsion paint are required for 1,000 sq.ft of wall area?

1,000 sq.ft of prepared wall surface requires approximately 8.5 to 9.5 litres of interior wall primer (1 coat @ ~110 sq.ft/litre) and 8.0 to 9.0 litres of premium interior emulsion paint (2 coats @ ~120 sq.ft/litre).

Q: Should wall putty be applied thicker than 2mm to hide uneven wall plaster?

Never. Polymer white-cement wall putty is engineered strictly as a thin 1.0mm–1.5mm pore-filling skim coat. Applying putty thicker than 2.0mm–2.5mm to compensate for wavy plaster causes shrinkage crazing and delamination; uneven walls must be corrected with gypsum or 1:4 cement plaster over bull-marks.

Q: Does Parth Enterprises undertake commercial office, industrial, and turnkey residential painting in NCR?

Yes. Parth Enterprises executes laser-inspected gypsum/cement leveling, mechanical vacuum sanding, airless spray painting for warehouses/basements, and luxury emulsion/PU finishes across Noida, Greater Noida, Gurugram, Faridabad, and New Delhi.

How Wall Putty (40kg Bags), Primer & 2-Coat Emulsion Paint Coverage Are Calculated (IS 2395 & IS 15489)

Deterministic Engineering Equation (IS 15489 / IS 2395)

2-Coat Wall Putty = Area ÷ 720 (40kg Bags)   |   1-Coat Primer = Area ÷ 110 (Litres)   |   2-Coat Emulsion Paint = Area ÷ 120 (Litres)

Under Indian Standard painting practice (IS 2395 for calcareous/cement substrates and IS 15489 for plastic emulsion paints), fresh internal cement plaster requires 28 days of moisture curing (surface moisture < 12%) before applying 2 coats of white-cement polymer wall putty (1.0mm–1.5mm total thickness, yielding ~18 sq.ft per kg or ~720 sq.ft per 40kg bag of Birla White / JK Putty). After 180-grit and 320-grit vacuum sanding, 1 coat of alkali-resistant wall primer (~100–120 sq.ft/litre) seals porosity before 2 cross-rolled coats of acrylic emulsion paint (~110–130 sq.ft/litre for 2 coats).
