Paint Quantity Calculator

Calculations for Paint Quantity 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

Calculation Procedure

• 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
