  • 300 LBS. BUOYANCY, 2LBS/CU FT DENSITY Perfect for use with boat parts and dock floats, and is approved by the U.S. Coast Guard. It also works well for insulation, soundproofing, sound deadening, expansion gaps, and filling of voids.
  • EASY TO MIX, SHAPE, AND SAND Simply mix parts A and B of the liquid resin component system in a 1:1 ratio, mix for 45 seconds and pour. Expansion starts in 45 seconds and is fully expanded in about 7 minutes. Additional layers can be added for strength and can easily be cut or sanded to any desired shape.
  • COMPATIBLE WITH OTHER MATERIALS Strength and compatibility are important with a quality pour foam. Our foam is versatile and bonds well with polyester, epoxy, or vinyl ester resin coatings. It also adheres to itself so you can build multiple layers by pouring the mix in separate batches to form strong bonds between layers.
  • WATERPROOF 94% RIGID CLOSED CELL FOAM Once the foam is cured, it helps prevent moisture absorption in marine and boat environments. The closed cell structure is also not affected by solvents, oil or gas.
  • ENVIRONMENTALLY RESPONSIBLE At Fiberglass Warehouse, we care about the environment and about your health. Thats why our pour foam contains no CFC propulsion agents or other Ozone depleting chemicals. Our materials also contain relatively low VOC emissions. Personal Protective Equipment PPE and proper ventilation is recommended during use.

    • Expands really quick, be ready when you mix.
It expands quicker than what I usually buy. Expands well. I used it to fill wooden pontoons for a homemade pontoon boat I am building. worked great. bought more for the other pontoon.

    • Patience is the key!
Take your time and use small amounts! When it says pour at 30 seconds, don't expect to pour at 32 seconds! But it worked great and I do recommend. Watch the video for this! You wont be sorry. Shipped quick.

    • Fun Experiment
It was a satisfying science experiment watching the foam grow, but, boy, did it make a mess. Unless you absolutely cannot cut pre-cast foam to fit what you're doing, it's not worth the money or hassle. It's also not aesthetically pleasing even if you mix it well; discolorations are inevitable. Therefore, the only use case I can recommend is if you have a hard-to-reach area that will not be visible to the eye. ... show more

    • Not a fiberglass layup epoxy.
This epoxy is meant for table tops. If you are doing fiberglass layup work get the epoxy specifically called out for building things like boats

    • Product is easy to use, Great buy!
We needed to patch up our dock, some animals ate through the foam. This was easy to use, just get red cups, mix & pour. Easy to carve, wax down your hands ahead or wear gloves!! The two bottles filled up about half the dock.

    • Quality and Quick.
This was the second pour foam I bought the first was not quite enough and expanded slower. This product was much faster and was set and harden within 5 minutes. Well worth the money and worked great as floor foam in my Jon boat.
