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
