# WHAT IS THE QUANTITY OF PAINTS CALCULATION FORMULA

The quantity of Paint calculation formula for a wall is very easy and very simple in quantity surveying. Today in this article we are going to discuss this calculation. For paint quantity calculation we mainly use thumb rules and in this example, we are using it so.

Let’s sole this example which helps to understand well about the calculation of paint.

## EXAMPLE:

Let’s consider or supposed that we have a wall having a Length 10 feet and having a Width 20 feet and there is no door and window in the wall. To calculate the quantity of paint is going to use in drywall (Old wall) as well as the wet wall (New wall) and also calculate the price of the paint if 1-gallon paint = 1000/-Rs. v

#### Given Data:

Length of the wall = 10 Feet.

The width of the wall = 20 Feet.

Condition = Calculate the paint quantity foe Wet wall and Drywall also.

#### Solution:

First, we have to calculate the area of the wall then we calculate the quantity of the paint for the wet wall (old wall) and then drywall (New wall) going to use under the given data of the wall.

Area  = Length x Width

Area of the wall = 10 feet x 20 feet  = 200 Square feet..

So the area of the wall is 200 square feet. Know we calculate the paint quantity in both types of the wall Wet walls as well as Dry walls. For further calculation note these points

We have two types of gallons one called.

One Uk Gallon = 4.54609 Litters (Also called imperial gallon)

One U.S Gallon = 3.785 Litters

And in this example, we are using U.S gallon.

#### Wet Wall Paint Quantity:

For wet wall means old wall we consider that the 1-gallon paint can cover up to 350 square feet  Area (This ratio is not fixed but we take it as a thumb rule for calculation).

Paint Quantity = Area of wall / Paint covered Area

= 200 / 350

Paint = 0.5714 gallons = 2.163 litters.

Price of the paint = gallons x paint price

= 0.5714 x 1000

Price = 572/- Rs.

#### Dry Wall Paint Quantity:

For drywall, paint calculation means old wall we consider that the 1-gallon paint can cover up to 200  Area (Again this ratio was not fixed but we take it as a thumb rule for calculation).

Paint Quantity = Area of wall / Paint covered Area

= 200 / 200

Paint = 1 gallons = 3.785 litters.

Price of the paint = gallons x paint price

= 1 x 1000

Price = 1,000/- Rs.

So in this way we are able to calculate the quantity of the paint is going to use in the wall.

Note: This calculation is not applicable for Enamel paint quantity calculation.
