CHOOSING THE RIGHT POUR FOAM

Select The Right Foam For Your Project

Marine pour foam is available in different densities and formulations designed for flotation, buoyancy, void filling, and structural support applications. Choosing the correct foam depends on the size of the area being filled, the amount of flotation required, and the overall demands of the project.

Whether you're restoring a boat, replacing waterlogged flotation foam, rebuilding a transom, or constructing a new composite structure, selecting the right marine foam helps ensure long term performance, stability, and reliability.

Boat Flotation Repair

Replace damaged or waterlogged flotation foam to help restore buoyancy, safety, and performance in boats of all sizes.

Void Filling Applications

Fill hard to reach cavities, compartments, and enclosed spaces with expanding closed cell foam for added support and flotation.

Marine Restoration Projects

Ideal for boat restoration, transom rebuilds, pontoon repairs, and composite construction projects requiring dependable flotation and support.

POUR FOAM FAQ

Frequently Asked Questions

What is marine pour foam?

Marine pour foam is an expanding closed cell foam used for flotation, buoyancy, void filling, and support in boat repair and composite applications.

Is pour foam waterproof?

Closed cell marine pour foam is designed to resist water absorption, making it suitable for many marine flotation and below deck applications.

How much pour foam do I need?

Measure the cavity or area being filled, calculate the volume, and compare it to the foam expansion rate listed for the product.

Can pour foam be used below deck?

Yes. Marine pour foam is commonly used below deck, inside hull cavities, and in flotation chambers when properly applied.
