Review: Excellent Closed Cell Foam for Small Projects
Review: Very good - just what I needed

## 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

## Questions & Answers

**Q: Can you press dents into this with your fingers once it’s fully cured?**
A: If you pour too much, too fast, you can create less dense regions that you can press your finger into. If you are patient with your pour it's pretty dang rigid - with that being said, if you put a tremendous weight through your thumb, you can still dent it a bit, but it's not easy to deform (I'm a 180 lbs male of average strength).
