How often should antifouling be renewed?
Antifouling does not automatically need a complete annual rebuild. Product type, remaining film, fouling, damage and the technical data sheet determine what is required.
How many coats of antifouling are needed?
The correct coat number is product-specific. See concrete Seajet examples and learn why primer and antifouling quantities must be calculated separately.
How long does antifouling last?
Antifouling life depends on product, film thickness, cruising area, time afloat and use. Inspection and the data sheet are more reliable than a universal annual rule.
Whether a boat needs antifouling depends mainly on time afloat, cruising area, fouling pressure and cleaning options. Trailer boats can often manage without a permanent coating.
Which antifouling is suitable for GRP boats?
Self-polishing, hard and biocide-free systems can all suit GRP boats. Cruising area, speed, time afloat and the existing coating determine the right choice.
Antifouling limits fouling either with authorised active substances or through physical surface properties. Compare the main systems and how they work.
Existing antifouling can be overcoated when it is sound, clean and compatible. Learn when direct overcoating, a barrier coat or full removal is required.
Which antifouling is suitable for sports boats?
Hull material, maximum speed, time afloat and fouling pressure determine the right coating for a sports boat. Compare self-polishing, hard and biocide-free systems.
