Measurement for all plastering should be taken from the dimensions before plastering for length and from top of floor or skirting to the ceiling for height.
How do you calculate plaster work?
Note: By considering dry density of sand = 1550 kg/m3….Strength of plastering/nominal mix:
| Plaster type | Description |
|---|---|
| 15mm | 15 MM cement plaster is required on the rough side of 9” and 4.5” wall. |
| 18mm | 18 MM thick cement plaster with neat cement slurry is required for making ‘Dado’ with the cement concrete flooring. |
How do you calculate wall plastering?
Based on the specified kind of mixture and plaster thickness, multiply your area with the corresponding values from the plaster proportion table:
- Quantity of Cement Bags = Area * Cement multiplier for a Class “B” mix.
- = 1.152 bags ~ 2 bags.
- Quantity of Sand = Area * Sand multiplier for a Class “B” mix.
- = 0.096 m3
How do you measure plaster thickness?
The actual thickness will vary at different locations on the wall and within a single sample. To further support the variation in thickness, the code calls for the plaster thickness to be measured from the back plane of the plaster metal base (essentially face of framing) outward and not the actual thickness of cement.
How do I calculate plastering costs?
Subtotal material cost = cement cost + sand cost = 46 +42 = INR 88. step 4 :- labour rate and charges:- labour rate and cost for external wall plastering is INR 18 to 25 per sq ft and INR 193 to 269 per sq m, consider labour rate and cost in this calculation is INR 225 per sq meter. Total cost = 313 + 47 = INR 360.
What is the ratio of plaster?
Different ratios of Cement mortar used for plastering are tabulated below:

How to check the quality of plastering work?
Ensure plastered surface is cured for the entire recommended period. Ensure the 1-meter level markings are made along all walls. Measure the ceiling from this level – it should be even at all points. [Check for ceiling plaster] Ensure plastering thickness is even at all points during plastering. Ensure the button marking tiles are removed.
How big of a layer of plaster do you need?
Do not plaster for a thickness of more than 15mm. In case it is required, the plastering should be done in 2 coats. The first layer applied should be cured for a day before applying the subsequent coats.
How big should a plaster cornice be on a wall?
Small decorative plaster cornice, (up to 80mm profile). Measure each wall with a 2 to 3mm tolerance. 4mm on external cornices. Medium decorative plaster cornice, (up to 150mm profile). Measure each wall with a 3 to 5mm tolerance. 5mm on external corners. Large decorative plaster cornice, (over 150mm profile).
How to check for undulations on Wall After plastering?
After plastering check the surface for undulations using halogen lamps. Yellow light is thrown on the plastered wall from one side shows undulations, if any, rectify immediately while the plaster is still fresh. All cut-outs such as fan, junction box, electrical box and skirting line should be finished to perfection.
