Top plate to attic drywall air sealing is consistently ranked as the #1 air sealing location. Great Stuff Pro™ Gasket forms a seal between framing lumber and drywall, which can result in up to 1.6 ACH50 reductions.
Great Stuff Pro™ Gasket is a one-component, water-based foam applied to the top plate, bottom plate and around the perimeter of all rough openings. Specially designed to create a flexible, compressible, air seal that will stay in place when drywall is installed. Unlike traditional polyurethane-based foam sealants, this water-based solution and the specially designed gun can be easily cleaned with a garden hose and the included cleanout adapter.*
*Follow all directions for proper cleaning and disposal. Use only the special blue-handled
Great Stuff Pro™ Gasket Dispensing Gun is to be used with Great Stuff Pro™ Gasket. Do not use other Great Stuff Pro™ products in this gun.
What is Great Stuff Pro™ Gasket?
Great Stuff Pro™ Gasket is a flexible, water-based, one-component foam designed to form an interior gasket between framing lumber and drywall, which improves air sealing performance. Material is applied and allowed to dry to the face of the top plate, bottom plate and around the perimeter of all rough openings before installing drywall. The unique gasket performance allows product use without any changes to construction sequencing.
Where is the preferred application location?
Any location where drywall will be installed tight against framing lumber is particularly suitable for Great Stuff Pro™ Gasket. In particular, the face of top plates, bottom plates and the framing around rough window and door openings, as well as inside and outside framing corners.
Can I continue to use my current drywall installation methods?
Once dried, Great Stuff Pro™ Gasket is designed to tolerate standard drywall installation techniques, including when boards are placed against the wall studs and slid up to meet the ceiling drywall. While this motion may deform the round gasket bead profile to a "shark fin", it will remain in place on the top plate and keep its thickness to seal the gap between the top plate and back side of the drywall.
Can I clean the Great Stuff™ Blue gun?
The water-based product can be cleaned from the Blue handled gun with the cleanout adapter provided in the Great Stuff Pro™ Dispensing Gun packaging. Remove the empty can, dispense residue from the gun, screw the adapter into the gun's basket, screw this assembly onto a garden hose or similar source of water.
How can I store Great Stuff Pro™ Gasket if I don't use the entire can?
The can may be left attached to the Blue Great Stuff Pro™ Dispensing Gun for up to 90 days. Close the adjustment dial and store up-right where the can will not be punctured. To restart, shake vigorously for 60 seconds, dispense a small amount of foam into a trash can until normal bead expansion is observed. Proceed with normal application
Is Great Stuff Pro™ Gasket an insulation?
No. This product is an air sealant and functions best when compressed as a gasket.
