Drywall Gasket

Great Stuff Pro Gasket Foam

Great Stuff™ Pro Gasket Foam is a water-based, flexible foam sealant designed to create an airtight, durable seal between drywall and framing before installation. Unlike expanding foams, it lays down as a non-expanding bead that stays soft and compressible—perfect for sealing top plates, bottom plates, and corners without bowing or damaging drywall. Ideal for high-performance, energy-efficient builds, it helps reduce air leakage and improve indoor comfort.
