Expanding Foam / Pour Foam

Pour Foam – Expanding Flotation Foam for Marine and Structural Applications

How Much Does 2-Pound Pour Foam Expand and What Volume Will It Fill?
Mixing 1 gallon of Part A with 1 gallon of Part B produces approximately 9 cubic feet of expanded 2-pound foam. That is roughly 34 times the combined starting liquid volume, although actual yield depends on temperature, mixing and application conditions.
How Much Does 4-Pound Pour Foam Expand and What Volume Will It Fill?
A 4-pound density pour foam expands to roughly 4.5 cubic feet per mixed gallon set (1 gallon Part A + 1 gallon Part B).
What Are the Mix Ratios for Marine Pour Foam and How Does Expanding Foam Work?
Marine pour foam is a two-part expanding polyurethane foam mixed 1:1 by volume (equal parts Part A and Part B). Fiberglass Florida carries 2 lb and 4 lb density foams.
