How Much Pool Paint Do I Need for My Pool?

There are a couple of factors to consider when determining how much pool paint that you need to paint your pool.

1. Is the surface porous, rough, or bare? If so, you may need about 25% more product then what is stated in the formula below. This will allow for the absorbtion of the 1st coat of swimming pool paint to properly cover bare, rough, or a sandblasted surface.

2. They type of pool paint you use also factors in to how much you will need.

Here are some good guidelines and estimates for calculating how much pool paint you will need for your size swimming pool.

Pool Paint Coverage Calculation

1. First you need to determine the square footage of your pool. To do this use this formula: (Length of the Pool) x (Width of the Pool) x (1.7) = Estimated square footage of your pool

Example:  If you pool is 35ft long and 15 ft wide, then you would use this formula:

Example: 35 x 15 x 1.7 = 892.50 square feet

2. Next, you need determine the total pool paint coverage with two coats of pool paint. Since you need 2 coats when applying any pool paint, you need double this amount:

Example: 892.50 x 2 = 1785 total square feet of coverage needed

3. If the type of paint you are using is a 2 gallon epoxy kit such as:

Then divide the above amount by 500. This number will give you the total number of 2 gallon kits needed. (Remember to always round up!)

Example: 1785 / 500 = 3.57 or 4 –  2 gallon kits ( add 25% for bare, rough, or a sandblasted surface which would be 4.66 or  rounding up to 5 –  2 gallon kits!)

If you are using any other gallon of pool paint such as:

Then divide the number by 300. This number will give your the total number of gallons needed. (Remember to always round up!)

Example: 1785 / 300 = 5.95 or 6 gallons ( add 25% for bare, rough, or a sandblasted surface which would be 7.44 or  rounding up to 8 gallons!)
