6 mm thickness of cement plaster and cement mortar 1 3 or 1 4 is recommended for cement plastering on rcc surfaces on the rcc walls fascia etc.

Roof plastering ratio.

Always use good quality of cement different grades of cement as well as good quality sand. The thickness of plaster is between 12 mm to 15 mm. Area width x height 10 x 10 100m 2. 4 1 part of cement and 4 part of sand.

Always use measuring box for measuring the quantity of sand and cement at the site. Recommended plastering cement sand ratio are 1 3 for repair 1 4 for external wall ceiling roof concrete plastering 1 5 internal brick wall plastering have no fine sand 1 6 for internal brick wall plastering whick have fine sand general used in civil engineering building construction. Plastering work ratio calculation. 100 m 2 x 0 012m 1 2 m 3.

Ratio of cement and sand for plastering the ratio of cement and sand for plastering is given below. The ratio of secondary coat of plastering cement sand 1 3 with the thickness of 8mm. For a better understanding we are going to do this calculation for 100 sq m area. Required volume of cement 1 4 x 1 55 void ratio x mortar volume 1 4 x 1 55 x 10 0 015 0 058 cum or 1 67 bags required sand volume 3 4 x 1 55 void ratio x mortar volume 3 4 x 1 55 x 10 0 015 0 174 m 3.

Or as directed by the engineer. Plastering thickness 12 mm 12 1000 0 012m. To calculate the cement and sand for 100 m 2 plastering area in 1 6 ratio and 12 mm thickness. Ratio of first coat of plastering cement sand 1 5 with the thickness of 12mm.
