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.
  • This expandable foam is recommended for void filling in nonstructural applications. It can be poured underneath decks and inside cavities where a lightweight flotation foam is needed to provide buoyancy.
  • 2# Density polyurethane flotation Foam Quart Kit; Consists of 1 pint of Part A and 1 pint of Part B and produces 1.25 cubic feet.
  • Once fully cured this foam can be laminated over with any type of polyester, epoxy or vinyl ester resin without melting.
  • 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 Great
I used this to add buoyancy to my kayak. It’s easy to mix up but pour as soon as you mix it. I’d say 2c ft is about accurate. It has a really weird smell.. almost like an artificial cake smell. Hopefully the smell will dissipate over time.

This stuff is amazing for filling up space and gaps. It's super lightweight so it doesn't add weight to my trolling motor battery case. It's easy to cut and trim once it's cured and it sets up within a few minutes in 75 degree temps.

The media could not be loaded. I used the foam to fill in the area around my diy rod locker. Before starting I used some gap filer to fill in the holes before and after this area, preventing it from going into places I did not want to go. The 1 quart kit was more than enough for my use. Will buy from again. ... show more

    • 2 Lb Density Expanding Pour Foam
Used the 2 Lb Density Expanding Pour Foam for replacing the floatation foam on my Lund rebuild at the transom area. Followed easy to follow directions and it worked well for refilling the removed foam area.
