How much antifouling do I need?

You can work out the amount of antifouling paint you need using these simple steps:

  1. Work out the area you’ll need to paint using the formula that fits your boat type below.
  2. Divide the area by the coverage of the paint you’ve chosen to work out how many litres per coat you’ll need.
  3. Finally, multiply the litres per coat by the number of coats to give you the total amount of paint required.
