TotalBoat Marine Flotation Foam is great for filling voids, especially under decks. It’s thermal and sound-proofing abilities make it ideal for a number of other insulation and flotation applications. 94% closed-cell foam structure lets it maintains buoyant pressure even after prolonged exposure to water.

This 2-part, pour-in-place expanding polyurethane boat foam reaches full expansion in about five minutes, and can be poured in multiple layers with excellent bonding between layers. The cured foam hardens into shape with minimal shrinkage, is not affected by gas or oil, and resists mold and mildew. Once fully cured, foam can be laminated over with polyester, epoxy, or vinyl ester resins.

• Density: Available in 2 lb. or 6 lb. density foam. The densities refer to the weight per cubic foot (12" x 12″ x 12″) of expanded foam
• Size: 2-Quart Kit and 2-Gallon Foam Kit
• Color: Brown transparent liquid (resin and activator)
• Expansion rate: Flotation foam begins expanding 10-20 seconds after mixing, and will continue to expand for about 5 minutes (in 70-80°F conditions)
• Compliance: Both foam densities have been tested in accordance with the USCG Regulation #33 CFR 183.114.
• Note: Continuous water submersion can eventually lead to loss of buoyancy over a period of years.
• Storage: 33-95°F – DO NOT ALLOW TO FREEZE

Uses for 2 lb. Density Boat Flotation Foam

• Lightweight foam is perfect for filling non-structural voids
• Pour beneath decks and inside cavities to provide buoyancy

Uses for 6 lb. Density Flotation Foam

• Higher compressive strength is great for filling cavities to support heavy loads
• Flotation for buoys
• Creating sculptures and other works of art
