The Gasket Guru

A gasket that’s durable and flexible? Just the product you need to form an airtight seal between framing lumber and drywall.


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


  • U.S. only
  • Available in 18-oz. cans

 Down To The Details Of GREAT STUFF PRO™ Gasket


A unique product needs a special dispensing gun.

Designed specifically for GREAT STUFF PRO™ Gasket, the blue-handled dispensing gun allows for precise application of the foam. It is restartable/reusable, and can be easily cleaned using a garden hose and the included cleanout adapter.

Note: The traditional polyurethane GREAT STUFF PRO™ Dispensing Gun is not adequate for dispensing this latex-based technology. These guns are not interchangeable.
