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 gallons
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.
Pain covered area = 200
Quantity of paint = 180/200 =0.9 gallon.
Price of 0.9 gallon paint = 0.9 x 1200 = 1080 Rs.
1. If the wall has any openings, subtract the area of openings from total area & then calculate paint quantity.
