QUANTITY ESTIMATION OF PAINTING WORK

HOW TO CALCULATE QUANTITY OF PAINT FOR BUILDING:

Painting is one of the most essential steps to be done after construction of any building/house.
Painting is done to protect the surface of the walls as well as to increase appearance.

                                                  

In this article, I will discuss how to calculate the quantity of paint required in a building.

Before starting the calculation let me tell you one important thing that quantity of paint is calculated in gallon.

There are two types of gallon

                                                                                                               

US gallon and Uk gallon.

1 US gallon = 3.785 litres

1 Uk gallon = 4.546 litres.

In this calculation we will use US gallon.

Let the length of the wall = 15 feet

The height of the wall = 12 feet.                                 

Area of the wall 15 x 12 = 180 sft.

THUMB RULE FOR PAINT CALCULATION:

Generally, 1 gallon of paint can cover up to 350 sft area of wet wall and

1 gallon of paint can cover up to 200 sft area of dry wall.

                             

PAINT QUANTITY OF WET WALL:

Area of wet wall =180 sft

Paint covered area = 300 sft

Quantity of paint = 180/350 = 0.514 litre.

Let the price of 1 gallon paint = Rs 1200.

Price of 0.514 gallon paint = 0.514 x 1200 =  617 Rs.

PAINT QUANTITY OF DRY WALL:

Area of dry wall = 180 sft.

Paint covered area = 200

Quantity of paint = 180/200 =0.9 gallon.

Price of 0.9 gallon paint = 0.9 x 1200 = 1080 Rs.

Note:

1. If the wall has any openings, subtract the area of openings from total area & then calculate paint quantity.
