GREAT STUFF PRO™ Kit, 18 oz. Flexible Drywall Gasket, Latex Foam Gun, Choice of 6 or 12 cans.

GREAT STUFF PRO™ Gasket gives contractors a better way to improve air-sealing between a 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.

This listing provides the choice of 1/2 Case (6 cans) or a Full Case (12 cans) and a Great Stuff Pro Gasket Dispensing Gun.

How it works:

GREAT STUFF PRO™ Gasket is a one-component foam applied to the face of the top plate, bottom plate and around the perimeter of all rough openings. Drywall is then installed normally over the Great Stuff Gasket creating a gasket that seals the building airtight.

Unlike polyurethane-based Great Stuff Pro Insulating Foam Sealants, Great Stuff Pro Drywall Gasket cures to 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 flexibility of the cured gasket allows for 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

GREAT STUFF PRO™ Gasket Dispensing Gun
