Fibre Glast 2-Pound Density Polyurethane Mix-and-Pour Foam - 4.9 pounds (2 Cubic feet) - Fill Cavities for Flotation and Reinforcement

Description

This 2 lb. density foam comes as a two-part kit, both parts equally mixed. It is a closed-cell system, meaning individual cells of foam trap in air and keep liquids out. As a result, it is most frequently used for flotation applications, delivering 60 pounds of float per cubic foot. It can be used to fill cavities for reinforcement and insulation, and can be shaped or carved, once cured, for use as a plug in mold-making or sculpting.
