Boat & Dock Foam Kits

We’re passionate about all things boating, including our easy to use flotation foam kits.

Whether you need to fill an entire hull or simply want extra buoyancy or additional structural integrity, our marine foam kits will have you out on the water in record time.

FSI boat & dock foam is two-part, closed-cell polyurethane foam. When mixed in equal parts and poured in place it provides excellent flotation properties. In addition to adding extra buoyancy and structural integrity to your boat or dock, it can also be used to insulate live wells and coolers.

Our flotation foam kits are environmentally friendly, with no ingredients or agents that harm waterways or the environment. Enjoy peace of mind knowing you’re making a sustainable choice that helps safeguard our ecosystem – at no extra cost.
