Plaster Calculator Plaster Calculator Estimates the sand and cement required to plaster a given wall. Length (m) * Length of the wall Height (m) * Height of the wall Select mix ratio * 1:41:51:6 Thickness (mm) * The thickness of plaster Area (m2) Calculated wall area Sand (m3) The volume of Sand required Cement (Bag 50kg) Number of cement bags required NB: While all information in the calculator is supplied in good faith, no liability can be accepted by Civilconsctructiontools.com team as actual use is beyond its control.

The plaster thickness is taken as t= 15mm and mix ratio as 1:4. Wall Area (A) = L x H =12×2.6 =31.2 m2 Mortar wet Volume (Vw)= A x t =31.2 x 15/1000 =0.468 m3 To convert from wed to dry volume , we must increase the wet volume by 33%. Add 25% allowance to fill up uneven wall surface and joints. Dry volume (Vd) = Vw x 1.33 x 1.25 = 0.468 *1.33 x 1.25 = 0.778 m3 Mix ratio total 1+4 =5 Cement part=1 Sand part =4 Dry sand volume = (Vd* Sand part)/total ratio = 0.778 x 4/5 = 0.622 m3 Cement Volume = (Vd* Cement part)/total ratio = 0.778 x 1/5 =0.156 m3 The density of cement is 1440 kg/m3 Number of cement bags of 50 kg required for 1m3 =1440/50 =28.8 Bags Volume of one Cement bags = 1/28.8 =0.0347 m3 You could also just say 50/1440 =0.0347 m3 Number of cement bags required= 0.156/0.0347 = 4.5 Bags That’s all!
