MMS 2LB. Pour Foam is a high-performance, closed-cell polyurethane foam system designed for superior buoyancy and insulation. Sold as a complete kit including both Part A (Isocyanate) and Part B (Polyol), it mixes easily in a 1:1 ratio and expands rapidly to fill voids and cavities with a dense, rigid structure. Ideal for marine flotation, structural reinforcement, and general-purpose insulation, this foam delivers reliable results whether you’re building, repairing, or restoring. MMS Pour Foam is available in convenient quart and gallon kits.
