Plaster Calculator – Estimate Plaster Quantity

Calculate the amount of plaster (cement and sand) needed for walls and ceilings.

Plaster Area (sq ft)

Plaster Thickness (mm)

Mix Ratio (Cement:Sand)

Cement0.000 m³

Cement Bags (50kg)0

Sand0.000 m³

Plaster Calculator Formula

Wet Volume = Area × Thickness

Dry Volume = Wet × 1.35

Cement = Dry Volume / (1 + Ratio)

Area: 500 sq ft, Thickness: 12mm, Ratio: 1:4

Cement ≈ 4 bags, Sand ≈ 0.28 m³

What thickness for plastering?

Calculate the amount of cement needed for your project based on volume and mix ratio.

Calculate the amount of sand needed for your project in tons or cubic yards.

Calculate how many gallons of paint you need to cover walls and ceilings.
