How to Calculate Cement,Sand Quantity For Plastering?


Plastering is a process of covering hard surfaces and uneven surfaces with a plastic material called plaster or mortar to obtain a uniform, smooth, regular, clean and durable surface. A mixture of lime or plaster, sand and water sometimes with added fiber, which hardens to a smooth solid and is used to coat walls and ceilings.

How to Calculate Cement,Sand Quantity For Plastering?


Mortar Ratio = 1:6 
Plaster Thickness = 12 mm = 0.012 m 

Density of Cement =1440 kg/m³ 

1 m³ of wall  = 35.3147 ft³

Volume of Mortar =  1 x 1 x .012 
                                  = 0.012 m³ (Wet Volume) 

Dry Volume of Mortar = 0.012 x 1.30 = 0.0156 m³

  Quantity of Cement = 1/7 x 0.0156 x 1440
                                     =3.21 kg = 0.064 bag. 

Quantity of sand = 6/7 × 0.0156 x 35.314
                                =0.47 ft³.
