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.
  • 4LB. Density polyurethane flotation Foam 2 Gallon Kit; Consists of 1 gallon of Part A and 1 gallon of Part B and produces 4 cubic feet.
  • Once fully cured this foam can be laminated over with any type of polyester, epoxy or vinyl ester resin without melting.
  • The 4LB 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

    • Works as described
Works exactly as described as long as you follow instructions. I did a test batch and it didn’t turn out so good. I then put on a space heater and made sure the temperature was above the recommended 75-80F and mixed the two compounds as instructed. It worked perfectly for my DIY project, couldn’t be happier as it saved me a lot of headache. A word of warning though it hardens very quickly and becomes hard as a rock. Make sure you prepare the surface and block off anywhere you don’t want it to go. Act quickly and it will turn out well, once you pour there’s no redo. ... show more

    • Worked well. Expands a lot!!!
Easy to use. Just make sure you dont mix too much at once. Once mixed, this stuff expands quickly. So, work fast.
