Propspeed Foulfree Multi-Surface Coating - Medium

Propspeed Foulfree™ Multi-Surface Coating System - Medium is created for RIBs and stabilizing fins on yachts, containing everything needed to coat underwater components. It is designed for boaters who want Propspeed's industry-leading, biocide-free, foul-release protection across multiple underwater surfaces in one system.

Outboard lower units and bracket assemblies, stabilizing systems, thrusters, stabilizing fins, and RIB tubes all benefit from Foulfree's protection against marine growth, drag, and fuel efficiency loss. It applies in just 4 simple steps with only a 10-minute overcoat window, and you're back on the water in 12 hours, tested to ISO and ASTM standards across more than 20 substrate classes.

Key Features

• Covers 21.5 sq ft (2 m²), enough for a full running gear and lower unit application.
• 10-minute overcoat window keeps the multi-coat process moving without long waits between layers.
• 12-hour cure time gets the boat back in the water faster than some competing systems.
• Biocide-free foul-release protection works by preventing marine growth from gripping the surface, not by poisoning it.
• Tested on 20+ substrate classes, so it's proven compatible with most running gear materials.
• Includes a removal pad for prepping the surface before application.
