HandiFoam's 14 oz. Gasket Foam Flexible One-Component Polyurethane Spray Foam Sealant is designed for controlled sealing applications where a rigid, brittle seal may not be appropriate. The one-component formulation requires no separate mixing, simplifying application and reducing preparation time. Once dispensed and cured, the polyurethane foam conforms to uneven surfaces and helps limit unwanted air and moisture infiltration. Its gasket-sealing characteristics make it suitable for professional construction, HVAC, plumbing, and general maintenance applications requiring a flexible foam sealant.
