Foulfree™ Multi-Surface System
Protection Powering Performance™
MULTI-SURFACE SYSTEM
FOUL-RELEASE COATING FOR UNDERWATER COMPONENTS
The Foulfree™ Multi-Surface coating system brings Propspeed’s industry-leading, biocide-free, foul-release protection to underwater components. Multiple components, many substrates, one system.
Outboard skegs, stabilising systems, thrusters, stabilising fins, and RIB tubes are all components that keep your boat agile, responsive, and ready for the water. When fouling strikes, drag climbs, fuel efficiency drops, and that perfect day on the water can suddenly turn into work.
The Foulfree Multi-Surface System prevents marine growth from taking hold, delivering invisible, non-invasive, biocide-free protection that blends seamlessly with your boat’s aesthetics. It’s easy to apply and engineered to deliver performance throughout the entire boating season!
AVAILABLE WORLDWIDE IN FEBRUARY 2026
A single coating system that applies quick and effortlessly to a wide range of underwater components. Multiple components, many surfaces, one system.
Industry-leading, biocide-free, foul-release protection that powers the performance of your underwater components.
Foulfree goes on in just 4 simple steps, with only a 10-minute overcoat window (20 °C / 68 °F). 12 hours later, you’re back on the water, doing what you love!
Foul-release, not antifoul. Foul-release coatings use physical means to reduce fouling, creating a surface that’s tough for marine organisms to adhere to.
