You can work out the amount of antifouling paint you need using these simple steps:
- Work out the area you’ll need to paint using the formula that fits your boat type below.
- Divide the area by the coverage of the paint you’ve chosen to work out how many litres per coat you’ll need.
- Finally, multiply the litres per coat by the number of coats to give you the total amount of paint required.

How to check the compatibility of existing coating
It is important to choose the best system for your boat. For most applications we offer two types of coating system: single-component (conventional) and two-component (high performance).
Video instructions
Learn how to to check if you have one or two component system on your boat by watching hempel's tutorial video, follow our step by step instructions, to check if you have one or two component system on your boat, to check if you have a one or two component system, apply hempel's thinner 871 (no 2) to a test area on your boat and leave it to work for 15 minutes..
Sand the surface with a scrapper or rub it with a cloth.
If it is tacky, you most likely have a one-component system on your boat and you should overcoat with another one-component system or remove the paint completely..
If the test area is not tacky, you most likely have a two-component system on your boat and you can overcoat either with a two-component or one-component system.

Most ablative / self polishing bottom paints require 2 coats since they are designed to wear away over time. More is better than not enough bottom paint! Most hard modified epoxy bottom paints will require just one good coat (just don’t miss any areas!)

How much antifouling do I need?
Determining how much antifouling you will need is fairly simple. Here are two quick guides to help you purchase the correct amount: 1. Calculate the area needing paint. For a rough estimate of the area to be painted, multiply the length of your hull (LOA) by the beam and multiply by 0.85 (LOA x B x 0.85 = Area). Then divide the area by the coverage of the paint you’ve chosen to determine how many quarts per coat you will need, or 2. Refer to the reference chart below for a quick estimate of how much antifouling paint is required for two coats:

This is a rough guide only. The amount of paint required is based on average conditions and application methods. Please check the individual product spreading rates and application guides if you require more precise information. You may need to change the Product type for each area you wish to paint i.e. the amount of paint required for a given area is not a combined total of primer and antifouling but the amount required of each product. The protection factor for all primers and antifouling is two coats for ‘good’ and three coats for ‘best’. The amount of paint applied with each coat varies considerably on the method of application so this is just a rough guide.
