12mm thick internal plaster

Considering 100sqm area

Proportion of C:M = 1:4

Summation of proportion =5

Quantity of one cement bag = 0.035cum

Quantity of wet mortar = 0.012 x 100 = 1.2cum

Adding 15% wastage = 1.2 + (1.2 x 0.15) =1.38cum

Volume of dry mix = 1.38 + (1.38 x 1/3) =1.84cum

Volume of cement = (dry volume / 5) x 1
                              = (1.84 /5) x 1
                              = 0.368cum
                              = 0.368 / 0.035
                              =10.5 bags

Volume of sand = (dry volume / 5) x 4
                          = (1.84 /5) x 4
                          = 1.472 cum
