Great Stuff PRO Flexible Drywall Gasket 18 oz, One Component, Water Based, Air Cured, Drywall Sealant for Use Only with Great Stuff Pro Gasket Dispensing Gun (Pack of 6)

GREAT STUFF PRO Gasket gives contractors a better way to improve air-sealing between framing lumber and drywall – a common area for leaks, adding up to 40% of a home's energy loss. Great Stuff Pro Drywall Gasket is the first water-based foam in the GREAT STUFF PRO Insulating Foam Sealant family. GREAT STUFF PRO Gasket is a one-component foam applied to the face of the top plate and bottom plate and around the perimeter of all rough openings. Drywall is installed normally over the Great Stuff Gasket, creating a gasket that seals the airtight building. Unlike polyurethane-based Great Stuff Pro Insulating Foam Sealants, Great Stuff Pro Drywall Gasket is a flexible, compressible foam that fits snugly to create a tightly sealed home and allows for a smooth, even drywall installation. It does not expand, which reduces drywall bowing. The cured gasket's flexibility allows heavy drywall to slide up the wall frame without the gasket tearing or releasing. Under normal conditions of 70°F/50% relative humidity, drywall may be installed after 6 hours of drying.
