How to use paint calculator

Let's understand with the help of an example, how to use the above paint quantity calculator

Assumptions for Example

  • Perimeter of Internal wall length Wise = 20 m = l
  • Perimeter of External wall length Wise = 30 m = b
  • Height of wall = 5 m = h
  • Carpet Area = 20 m2 = A
  • Window (Length, Width, Quantity) = (2 m , 2 m , 1)
  • Door (Length, Width, Quantity) = (3 m , 2 m , 1)
  • Putty consumption for 2 coat = 1.3 m2/Kg  
  • Primer consumption for 1 coat = 9 m2/L 
  • Paint consumption for 2 coat = 6.5 m2/L

Paint calculation procedure

Let's understand with the help of an example, how to use the above paint Calculator for Wall

Step 1: Calculation of Surface Area to be Painted

  • Surface Area=(((l +b) x h)+A -(Area of window +Area of Door))
  • = ((20+30)x5 + 20 - (2x2x1) - (3x2x1)) = 260 m2

Step 2: Calculation of Amount of Putty

  • Amount of Putty for 2 coat = Surface Area / 1.3
  • = 260 / 1.3
  • = 177 Kg

Step 3: Calculation of Amount of Primer

  • Amount of Primer for 1 coat = Surface Area / 9
  • = 260 / 9
  • = 25.55 L

Step 4: Calculation of Amount of Paint

  • Amount of Paint for 2 coat = Surface Area / 6.5
  • = 260 / 6.5
  • = 40 L

Final Result

  • Surface Area to be Painted = 230 m2
  • Amount of Putty = 177 Kg
  • Amount of Primer = 25.55 L
  • Amount of Paint = 36 L
