Painting Wall Material Quantity Calculator

Painting Wall Material Quantity

Multi-wall calculator with Skim Coat (Camstar) & Sealer (Jotun) — now with material densities & cement bags (approx)

Wall Panels

Add each wall (or segment). Leave cells blank if not known yet. Only rows with Length & Height > 0 are counted.

Net area from all valid panels: 0.00 m²

Topcoat Paint

Topcoat Coats

Coverage (m²/L)

Wastage (%)

Typical interior emulsion: 8–12 m²/L per coat; wastage 5–15%.

Sealer (Jotun)

Use Sealer (1=yes,0=no)

Coverage (m²/L)

Can Size (L)

Skim Coat (Camstar)

Use Skim Coat (1=yes,0=no)

Consumption (kg/m²)

Bag Size (kg)

Adjust consumption by surface smoothness; Camstar bags are 25kg.

Materials & Densities (for reference)

Cement Density (kg/m³)

Sand Density (kg/m³)

Brick Density (kg/m³)

Cement Bag Size (kg)

Note

Densities are shown for transparency. “Cement Bags (approx)” below uses skim weight as a rough proxy.
