Roof Plastering Ratio

Calculate the area of plastering.

Roof plastering ratio.

The ratio of secondary coat of plastering cement sand 1 3 with the thickness of 8mm. Or as directed by the engineer. The thickness of plaster is between 12 mm to 15 mm. For a better understanding we are going to do this calculation for 100 sq m area.

For roof plaster mainly ratio we use 1. 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. 4 1 part of cement and 4 part of sand. 100 m 2 x 0 012m 1 2 m 3.

Plastering work ratio calculation. Always use good quality of cement different grades of cement as well as good quality sand. Plastering thickness 12 mm 12 1000 0 012m. 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.

Area width x height 10 x 10 100m 2. Ratio of cement and sand for plastering the ratio of cement and sand for plastering is given below. 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. Ratio of first coat of plastering cement sand 1 5 with the thickness of 12mm.
