Easily calculate the cement and sand required for plaster work using this advanced plastering calculator. A useful and handy tool for construction workers.
Plastering refers to the thin covering that is applied to the surface of walls and ceilings. The phrase rendering is sometimes used to describe the process of finishing interior work with cement, lime mortar or other coarse materials.
Plastering is primarily used to cover the surface of a wall’s irregularities and to conceal the surface of the actual structure. Plastering also gives a wall a neat and tidy appearance, which is important in terms of aesthetics.

Steps to use this calculator are mentioned below:
- This online calculator is very user-friendly.
- To figure out how much plaster material you’ll need, start by measuring the length and width of the wall or ceiling and enter the dimensions in this calculator.
- Enter the thickness of the plaster to be applied is the next stage and input the cement mortar ratio in which the plaster is to be applied as well.
- This data will give you the exact plastering area and the quantity of the cement and sand required for plastering work.

How to Measure the Dimensions of the Wall
You don’t need to measure the dimensions of the wall if you have a house plan. The dimensions can be obtained straight from the plan. If you don’t have one, you’ll have to measure the length and height/width of the wall and ceiling by measuring tape.
The illustration below can help you clarify the concept.
How Many Plastering Coats Do I Need?
Wherever possible, the best number of coatings is two, with the undercoat followed by a finishing coat. However, it is acknowledged that much successful work has been done in the past with single-coat plaster finishing treatments on generally flat backgrounds of brick, concrete, and similar materials. Three coats of plastering may be required for exceptionally rough surfaces, such as rough stone masonry.
Thickness of Plaster
Finishing coats must be just thick enough to produce a sufficient body of material to harden adequately under the site conditions in any given scenario.
The overall thickness of two-coat work exclusive of keys or dubbing out shall be approximately, but not ordinarily, 20 mm and in the case of in-situ concrete soffits, it shall not exceed 15 mm. Three-coat work should have a thickness of roughly 25 mm, but not more than that.
