## plastering cement sand calculator

Assume we need to calculate plastering material quantity for 10 x 10 m ceiling. required plastering area = 10 x 10 = 100 m2 or square metre. plastering thickness = 12 mm. cement mortar ratio = 1:3 (1 part cement : 3 part sand) required volume of cement mortar = plastering area x plastering thickness = 100 x 0.012 = 1.2 m3.
