Roof Plastering Ratio

The ratio of secondary coat of plastering cement sand 1 3 with the thickness of 8mm.

Roof plastering ratio.

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. Plastering thickness 12 mm 12 1000 0 012m. 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.

For a better understanding we are going to do this calculation for 100 sq m area. 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. Ratio of first coat of plastering cement sand 1 5 with the thickness of 12mm. Always use good quality of cement different grades of cement as well as good quality sand.

Calculate the area of plastering. For roof plaster mainly ratio we use 1. 4 1 part of cement and 4 part of sand. The thickness of plaster is between 12 mm to 15 mm.

Area width x height 10 x 10 100m 2. Always use measuring box for measuring the quantity of sand and cement at the site. Or as directed by the engineer. To calculate the cement and sand for 100 m 2 plastering area in 1 6 ratio and 12 mm thickness.
