Hard Antifouling Paint

What Is Hard Antifouling?

Hard antifouling is the original, long‑lasting type of antifouling paint. Once immersed, it forms a tough, durable film that can be wiped down with a cloth or sponge without removing significant amounts of paint. Instead of wearing away, the coating stays intact while the biocides gradually leach out to prevent fouling.

When to Choose Hard Antifouling

Hard antifouling is the go‑to choice for:

• High‑speed power boats that demand a stable, non‑eroding finish
• Mud berthed boats on drying moorings, where repeated grounding would quickly strip softer paints
• Fresh water moorings, where eroding antifoulings may not activate or shed effectively
• Racing boats, where performance matters and a smooth, fair hull is essential

Why Racers Love It

Hard antifouling can be wet‑sanded to a super‑smooth finish, giving competitive sailors every possible hydrodynamic advantage. Because the paint film stays put, it’s ideal for anyone who wants to maintain a consistently slick hull throughout the season.
