    Product Description

    GREAT STUFF PRO™ Gasket gives contractors a better way to improve air-sealing performance between a home’s framing lumber and drywall – a common area for air leaks, accounting for up to 40% of energy loss1 . It is the first water-based foam in the GREAT STUFF PRO™ Insulating Foam Sealant family.

    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 following the standard application process, creating a gasket that seals the building airtight.

    Unlike polyurethane-based GREAT STUFF PRO™ Insulating Foam Sealants, this gasket solution 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 helps prevent drywall bowing.

    The flexibility of the cured gasket bead 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 time. In high humidity, 24 hours of drying time is recommended.

    This water-based, one-component sealant foam:

    • Improves air sealing by creating a gasket between drywall and frame.
    • Is applied to face of top plate, bottom plate and around all rough openings.
    • Compresses when cured preventing bowing issues with drywall board. A 1/2" bead can easily be compressed to < 1/16" by the force of screwing on drywall.
    • Withstands scrapping and rubbing when drywall is slid up the wall and put in place. Is tolerant of abrasive contact and maintains its seal.
    • Helps meet stricter energy codes.
    • Does not expand like traditional, one-component, polyurethane foam sealants.
    • Air cures in 2 to 24 hours, depending on humidity. Dries fastest at low humidity.
    • Creates a more stable indoor temperature, lowering energy bills.
    • Reduces moisture, mold, pollutants and allergens that creep through small openings.
    • Minimizes waste. Reusable for up to 90 days when left attached to GREAT STUFF PRO™ Dispensing Gun with the blue handle. Shake vigorously for 60 seconds before use.

    It’s the first water-based, polyurethane foam sealant:

    • Non-cured spills and drips means easy water clean-up
    • Low VOC
    • Easy gun clean-out with standard garden hose
