Deck Paint Calculator

Deck painting can be a daunting task, especially when it comes to estimating the amount of paint needed. However, fret not! With the Deck Paint Calculator, you can easily determine the gallons of paint required to cover your deck adequately.

Formula: To calculate the amount of paint needed for your deck, we use the following formula: Amount of Paint (gallons)=Area×Number of CoatsYield of Paint (sq ft/gallon)Amount of Paint (gallons)=Yield of Paint (sq ft/gallon)Area×Number of Coats​

How to Use:

  1. Enter the area of your deck in square feet.
  2. Input the number of coats you intend to apply.
  3. Specify the yield of the paint in square feet per gallon.
  4. Click on the “Calculate” button to obtain the amount of paint needed in gallons.

Example: Suppose you have a deck with an area of 500 sq ft. You plan to apply 2 coats of paint, and the paint you’re using has a yield of 250 sq ft/gallon. Using the Deck Paint Calculator:

  • Area of the Deck: 500 sq ft
  • Number of Coats: 2
  • Yield of the Paint: 250 sq ft/gallon Upon calculation, the amount of paint needed would be 4 gallons.
