How to Use This Calculator
  1. Enter the total surface area you need to coat in square feet.
  2. Set the target thickness per coat in mils (typical flood coats are 4–8 mils; 1 mil = 0.001 inch).
  3. Enter the number of coats you plan to apply.
  4. Enter the spread rate of your epoxy in sq ft per oz at 1 mil from the product data sheet.
  5. Read the total resin needed in ounces with 15% overage for drips and edge coverage.
  6. Use the gallons output to compare costs when purchasing resin in larger containers.
