Here is the useful Plaster calculator to calculate cement and sand for plastering. Dry volume of motor required for plastering = 1.27 X Wet volume of plaster. (1.) To get the weights of materials required in multiply it with its density, Cement required = 0.03048 cu.m. - YouTube 15 mm or 20 mm theek cement plaster used for external wall plastering and rough surface of brick wall. or 0.784 bags, Sand needed would be = (230/0.153)x 0.12 = 180 kgs or 5 cft. 2. Not recommended for general usage at sites. Plaster of mix ratio 1:4 mean that it contains one part of cement and 4 parts of sand by volume. or as directed by the Engineer, 6 MM to 10 MM thickness of cement plaster and cement mortar in 1:3 or 1:4 ratios is recommended for underside of RCC slabs. That’s a typo error. This is the most accurate method as it accounts for the variations in the Loose Bulk Density. Cement plaster is a homogenous mixture of Portland cement, fine aggregates, and water. Add three buckets of sand, half a bucket of cement, and half a bucket of lime. Dry mix the cement and plaster first – before adding water. = 0.12192 X 35.29 = 4.302 cu.ft. You can consider a wastage factor of 5% to the above calculation.
