How to calculate cement, sand quantity for Plastering



In this Article I will find the quantity of cement sand quantity for plastering, so after reading this article you will be able to know the calculation of mortar in plastering, And this method you can apply for any construction work where you want to find quantity of Plastering.

Given Data:

Ratio for Cement mortar for plastering = 1 : 6      where 1 is Cement and 6 is Sand

Thickness of plastering = 12mm

Here we will find the qauntity for 100 Sq.m area ( for wall )

Quantity of Plastering ( Cement and Sand )

Solution :

Area of Plastering = 100 sq.meter

Thickness of plaster = 12 mm

Ratio of cement mortar  =1 : 6

Quantity of Cement Mortar 

Plaster thickness =  12 mm        Convert to meter    = 12/1000 = 0.012m

Volume of Cement Mortar 

Area of Plastering x Thickness of Plaster

= 100 mx 0.012 m = 1.2 m3

The above volume is wet volume now we have to convert it to dry volume which we can get with 30% to 35%

So here we will take  35%

1.2 mx (1+0.2+0.35)



Ratio of Cement Mortar  = 1 : 6  sum of ratio = 7

Quantity of Cement =  1 / 7 x Dry volume of Mortar

= 1 / 7 x 1.86  = 0.265 m3

Now Convert the above volume of Cement to Cement Bags

We know that the one Cement bag ( 50 kg ) volume is  = 0.0347 m3

No’s of Cement Bags = 0.265 m/0.0347

= 7.66 bags  ( 8 Bags)

Quantity of Sand  = 1.86 x 6/7

= 1.59 m3
