Calculate plaster volume, cement and sand needed from wall area and thickness.
—
How to use
- Enter the plaster area in sq ft.
- Enter the thickness in mm — inner walls are usually 12 mm, outer walls 15-20 mm.
- Enter the mix ratio (usually 1:4 or 1:6).
- Cement bags and sand needed will show below.
Note: Uneven walls can increase the actual volume, so keep some wastage. Rates change — verify with the official source before relying on this.
