Plaster Area calculation

PlasterArea = Length × Width

Plaster Area = 10×10

Plaster Area = 100.00m2

Plaster Area = 1076.39ft2

Material calculation

Step 1:

Volume Of Mortar =PlasterArea  × Plaster Thickness In Meter

Volume Of Mortar = 100.00   ×  0.015

Volume Of Mortar = 1.50 m3

Note: Add 30% to fill up join & Cover surface


Volume Of Mortar =1.50 +1.50×0.3

Volume Of Mortar =1.95 m 3

Note: Increases by 25% of the total dry volume


Dry Volume Of Mortar =1.95 +1.95×0.25

Dry Volume Of Mortar =2.44 m 3

Step 2: Amount of Cement Require

= Dry Volume  × Cement RatioSum of Ratio ÷Volume of Cement Bag

= 2.44  × 14 ÷ 0.035

No. of Cement Bag Require =  17.41 Bags

Require Cement in Kg =  870.54 kg.
Note: 1 Bag of cement = 0.035 m3.
1 Cement bag contains = 50 kg cement

Step 3: Quantity of Sand Require

= Dry Volume  × Sand RatioSum of Ratio × Density of Sand

= 2.44  × 34 × 1550

Qauntity of Sand require :  2834 Kg

Qauntity of Sand require :  2.83 Ton
Note: By considering dry density of sand = 1550 kg/m3.
1000 kg = 1 Ton

What is plastering calculation?

Plastering is the process of covering rough walls and uneven surfaces in the construction of houses and other structures with a plastic material, called plaster, which is a mixture of lime or cement concrete and sand along with the required quantity of water.

Plastering is done to protect the surface of masonry from atmospheric influences, especially rain. It provides lateral stability by binding all bricks or stones and protects masonry joints.

Plastering Calculation
Area of Plastering = Length × Width

Amount of Cement = Dry Volume  × Cement RatioSum of Ratio ÷ Volume of Cement

Amount of Sand = Dry Volume  × Cement RatioSum of Ratio × Density of Sand
Where,
  • m2(Square meter) and ft2 (Square feet) is a total Area and sand in kg (kilogram), cement in bags
  • Here 1:4 ratio so 1 is part of cement and 4 is a part of sand 5 is total of cement and sand.
  • 4 is a part of sand.
  • 1550 is conversion m2 to kg of sand.

Note:
Here 1:4 ratio so 1 is part of cement and 4 is a part of sand 5 is total of cement and sand.

Requirements of good plaster:

  1. It should adhere to the background and should remain adhered during all climatic changes.
  2. It should be cheap and economical.
  3. It should be hard and durable.
  4. It should be possible to apply it during all weather conditions.
  5. It should effectively check the entry or penetration of moisture from the surfaces.
  6. It should possess good workability.

Strength of plastering/nominal mix:

Architects refer the following concrete code table in drawing. Knowing this table will help you in deciding the proportion of cement, sand and gravel in Plastering.

Plaster type Description
12mm 12 MM thick cement plaster is done where the plain surface of brick masonry is plastered.
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.
20mm 20 MM thick cement plaster is done in two coats in some cases on rough side of wall or according to the design requirement.

What are the importance plastering?

Plastering work can be one way to enhance the splendour of your house.Plastering done over interior as well as exterior makes it even and smooth which can add strength to the walls and ceiling along with increasing the attractiveness of the home.These can be used for both constructions of new buildings and restoration of age old buildings.This old buildings can include heritage buildings like Churches, old Victorian mansions, libraries, cemeteries, etc., which can be restored to its old world charm with the help of cornice plaster. You can also save the damage of wall due to rain and wind by using appropriate plastering..
