How much sand and cement do I need for plastering?
The ratios mentioned in plastering are volumetric ratios of Cement & Sand (Ex. Cement:Sand = 1:5, 1 part of cement and 5 parts of sand in a mortar). The overall thickness of plastering should be minimum 20mm including two coats. The Volume of each cement bag = 50Kgs/1440 = 0.0348 m3.
What is the best mix for plastering?
A standard ratio used in creating this mix is 6 parts sand, 1 part cement, and 1 part lime (6:1:1). There is no particular type of cement that should be used; any kind will do. However, the sand used ought to have a fine texture and be free from impurities. The best type of sand to use is rendering or plastering sand.
How do you calculate plaster mix?
Calculation of quantity of material for 12 mm thick plaster of ratio 1: 6 (1 Cement:6 Sand) in the wall for 100 Sqm
- Quantity of Cement = 2/(1+6) × 1 (1 Ratio of cement)
- In Kg = 0.30 × 1440 (Density of cement = 1440 kg/m3)
- Quantity of Sand = 2/(1+6) × 6 (6 Ratio of sand)
- In Cubic Feet = 63.558 cft (1 Cum = 35.31 cft)
Why does my plaster go hard quickly?
Some walls whether they be a backing coat or a re-skim, over old plastered walls, can be very porous and suck the moisture out of the plaster causing the plaster to become firm. It is not unusual on very porous surfaces for 3 coats of PVA (the dilution increasingly thickened) to be applied.
Can we use OPC cement for plastering?
OPC is available in two grades — 43 and 53. Both grades are considered best for plastering work. However, OPC 43 Grade is most commonly used because OPC 53 Grade sometimes causes shrinkage cracks to appear. Now go ahead, choose the right cement for your plastering work today.
How do I calculate plastering costs?
Subtotal material cost = cement cost + sand cost = 28 + 25 = INR 53. step 4 :- labour rate and charges:- labour rate and cost for internal wall plastering is INR 15 to 18 per sq ft or INR 161 to 193 per sq m, consider labour rate and cost in this calculation is INR 180 per sq meter. Total cost = 233 + 35 = INR 268.
How do you calculate concrete per square meter?
Cement Calculation Formula for Plastering-
- Density of Cement = 1440 kg/m3.
- Sand Density = 1450-1500 kg/m3.
- Density of Aggregate = 1450-1550 kg/m3.
- How many KG in 1 bag of cement = 50kg.
- Cement quantity in liters in 1 bag of cement = 34.7 litres.
- 1 Bag of cement in cubic metres = 0.0347 cubic metre.
