HandiFoam Gasket Foam Sealant for Outlets, Sill Plates & Small Gaps, 14 oz

HandiFoam Gasket Foam Sealant, 14 oz HandiFoam Gasket Foam is a minimal-expansion, one-component polyurethane sealant designed to act like a foam gasket — sealing snugly around small, tight gaps without excess expansion that would push materials out of alignment. It's a favorite for sealing behind electrical outlets and switch plates, along sill plates, and around other small penetrations where a low-rise, controlled foam bead is needed. Key Features Minimal-expansion “gasket-style” foam formula for tight, controlled gaps Reduces air infiltration and drafts around outlets, switch plates, and sill plates One-component polyurethane — no mixing or separate hardener needed Cures firm and can be trimmed for a clean finish Compact 14 oz can suited for detail work and smaller jobs Common Applications Sealing behind electrical outlet and switch plate covers Sill plate sealing between framing and foundation Small gaps and penetrations where high-expansion foam would be too aggressive General air-sealing and weatherization detail work Specifications Item #: P31003 Brand: Handi-Foam Net Weight: 14 oz Formula: Minimal-expansion gasket-style foam Always follow the manufacturer's label and Safety Data Sheet (SDS) for proper storage, handling, and application instructions.
