###### $\mathrm{Volume\; Of\; Mortar\; =}\mathrm{PlasterArea}\times \mathrm{Plaster\; Thickness\; In\; Meter}$

$\mathrm{Volume\; Of\; Mortar\; =}\mathrm{100.00}\times \mathrm{0.012}$

#### $\mathrm{Step\; 2:\; Amount\; of\; Cement\; Require}$

###### = $\left(\frac{DryVolume\times CementRatio}{SumofRatio}\right)\xf7\mathrm{Volume\; of\; Cement\; Bag}$

= $\left(\frac{1.95\times 1}{4}\right)\xf70.035$

$\mathrm{No.\; of\; Cement\; Bag\; Require\; =}\mathrm{13.93}\mathrm{Bags}$

$\mathrm{Require\; Cement\; in\; Kg\; =}\mathrm{696.43}\mathrm{kg.}$**Note: **1 Bag of cement **= 0.035 m**^{3}.

1 Cement bag contains **= 50 kg cement**

= $\left(\frac{1.95\times 1}{4}\right)\xf70.035$

$\mathrm{No.\; of\; Cement\; Bag\; Require\; =}\mathrm{13.93}\mathrm{Bags}$

$\mathrm{Require\; Cement\; in\; Kg\; =}\mathrm{696.43}\mathrm{kg.}$

**Note:**1 Bag of cement

#### $\mathrm{Step\; 3:\; Quantity\; of\; Sand\; Require}$

###### = $\left(\frac{DryVolume\times \mathrm{Sand}Ratio}{SumofRatio}\right)\times \mathrm{Density\; of\; Sand}$

= $\left(\frac{1.95\times 3}{4}\right)\times 1550$

$\mathrm{Qauntity\; of\; Sand\; require\; :}\mathrm{2267}\mathrm{Kg}$

$\mathrm{Qauntity\; of\; Sand\; require\; :}\mathrm{2.27}\mathrm{Ton}$

= $\left(\frac{1.95\times 3}{4}\right)\times 1550$

$\mathrm{Qauntity\; of\; Sand\; require\; :}\mathrm{2267}\mathrm{Kg}$

$\mathrm{Qauntity\; of\; Sand\; require\; :}\mathrm{2.27}\mathrm{Ton}$

**Note:**By considering dry density of sand

**= 1550 kg/m**

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

$\mathrm{Area\; of\; Plastering}=Length\times Width$

$\mathrm{Amount}\mathrm{of}\mathrm{Cement}=\left(\frac{\mathrm{Dry}\mathrm{Volume}\times \mathrm{Cement}\mathrm{Ratio}}{\mathrm{Sum}\mathrm{of}\mathrm{Ratio}}\right)\xf7\mathrm{Volume}\mathrm{of}\mathrm{Cement}$

$\mathrm{Amount}\mathrm{of}\mathrm{Sand}=\left(\frac{\mathrm{Dry}\mathrm{Volume}\times \mathrm{Cement}\mathrm{Ratio}}{\mathrm{Sum}\mathrm{of}\mathrm{Ratio}}\right)\times \mathrm{Density}\mathrm{of}\mathrm{Sand}$

- m
^{2}(Square meter) and ft^{2}(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 m
^{2}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.

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

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. |

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..
