Plaster Quantity Calculator
Work out the plastering for a wall. Enter the area, the coat thickness and the mix, and get the mortar plus cement and sand — with a both-sides option, since a compound wall is usually plastered on both faces.
External wall plaster is commonly ~15-20 mm (often two coats); internal ~12 mm.
For 100 sqm at 15 mm.
Uses a 1.27 dry-volume factor and the 1:6 (general) mix. Allow wastage, and remember external plaster is often two coats (rough + finish).
Indicative only. Real plaster quantities vary with the surface roughness, the number of coats, the mix and site wastage. This is for ordering and budgeting — confirm the thickness and mix with your contractor, and follow the site bill of quantities for the actual order.
