Features

  • Flotation Foam is a polyurethane 2-part foam that, when mixed in equal parts and poured in place this foam will soundproof, insulate, or provide extra buoyancy.
  • 6LB. Density polyurethane flotation Foam 1 Quart Kit; Consists of 1 Pint of Part A and 1 Pint of Part B and produces 0.375 cubic feet.
  • Once fully cured this foam can be laminated over with any type of polyester, epoxy or vinyl ester resin without melting.
  • The 6LB density also works well in floating decoy or taxidermy applications as well as many other sculpting, casting, carving and other filling applications
  • All expansion rates and times given are temperature critical. Temperatures below 75 F will lower the expansion rate therefore requiring more foam. Ideal working temperature is 75 to 80 F or above. Accurate measuring of these products is extremely critical. Working time before foaming: approx. 45 seconds Time before full expansion: approx. 5 minutes

  • Very good - just what I needed
The media could not be loaded. This saved me having to rip out and re-mortar a tub. First time mortar bed for fiberglass acrylic tub and the mortar shrank leaving voids. This fills the voids perfectly, it’s incredibly solid now. In case you’re wondering as I was, this will go through a tube to get it exactly where you need it. I was afraid it’d expand in tube before exiting. I had it mixed and poured in funnel though within 20sec. Void and tube in vid both 5/8 in. ... show more

  • Amazing stuff
This says 45 sec working time it very well means it. Mix fast and get it were you need it. Gets very hot in its reaction.

  • Waste of money!
This is the worst 2 part foam I’ve ever bought. It didn’t hardly expand at all. It had clumps all in one of the bottles. We waited to use when the temperature was optimal. This was a complete waste of money.

  • Doesn’t expand very much
Doesn’t expand very much I have been using a 2 lb foam from a different company I have set amounts I use but now with this I have to use twice as much to fill the same space granted this stuff is very dense
