## How To Calculate Quantity Of Paint For Building:

Painting is one of the essential steps to be done after constructing any building/house. Painting is done to protect the surface of the walls as well as to get a beautiful 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 the quantity of paint is calculated in gallons.

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 gallons.

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 sq.ft area of wet wall and

1 gallon of paint can cover up to 200 sq.ft drywall area.

### 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 of 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.

**Note:**

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