Always ensure you have enough quantity to complete the job with the required number of coats you need. It’s false economy to scrimp on the coating(s) so always ensure you have sufficient extra quantity for areas of high erosion such as the bow, waterline and leading edges of the keel and rudder.

Generally speaking, the performance of antifoul is directly proportional to the dry film thickness of each coat. Therefore, it is important that you apply the recommended quantity as a minimum for a satisfactory result.

The scientific approach is to divide the total surface area of your hull by the coverage rate (m²/litre) of the relevant product and this will tell you how many litres you require for one coat.
