How to Calculate Estimation of Wall Plaster.

Assume:

Wall = 1m Length, 1m height

Mortar Ratio = 1:6

Plaster Thickness = 12 mm =0.012 m

Constants:

Density of Cement = 1440 kg/m3

1 cum = 35.3147 cuft.

So:

Volume of Mortar = 1 x  1 x 0.012 = 0.012 cum. (Wet Volume)

Dry Volume of Mortar = 0.012 x 1.30 = 0.0156 cum. 

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

Quantity of Sand     = 6/7 x 0.0156 x 35.3147 = 0.47 cuft.

The recommended thickness of cement plastering is given below. Recommended thickness of plastering for brick walls is 12 MM, 15 MM or 20 MM. 12 MM thick cement plaster is done where the plain surface of brick masonry is plastered. 15 MM cement plaster is required on the rough side of 9” and 4.5” wall.
