Great Stuff™ Wide Spray Foam Sealant from DuPont Performance Building Solutions is a new broad-coverage spray foam ideal for air sealing seams, joints, large gaps, irregular surfaces, and hard-to-reach spaces. The one-component foam sealant expands up to one inch, creating a durable, airtight, and weather-resistant seal. 

Designed for fast application, it adheres to both vertical and horizontal surfaces without sagging. With a simple, hassle-free formula that requires no complex setup, mixing, coveralls, or respirators1, the foam sealant can streamline the process, helping to save both time and money.

“We’re excited to expand and strengthen the Great Stuff portfolio with the launch of our new Wide Spray Foam Sealant,” said Melissa Helpinstill, global business leader for DuPont Performance Building Solutions. “In a category of its own, Great Stuff Wide Spray is an innovative product developed in response to customer feedback, offering a quicker, easier way to seal wide gaps and tight spaces compared to bead foam. Its lightweight, shake-and-spray design makes covering large areas effortless, helping users complete even the toughest jobs with greater efficiency.”

The all-in-one Great Stuff Wide Spray kit includes two 18-ounce cans of Great Stuff Wide Spray, covering up to 60 linear feet when sprayed in a four-inch-wide band. The kit also comes with four nozzles that allow users to tackle a variety of challenging applications, including two white cone nozzles, spraying up to four inches wide for more precise sealing in tight spaces and two blue fan nozzles, spraying up to six inches wide for broad coverage from a distance. The fan spray is perfect for top plates, corner bottom plate junctions, California corners, and HVAC junctions, while the cone spray is ideal for picture framing, rim joints, and attic can lights.

Additional benefits of the new spray foam sealant include the following:

  • Adheres to wood, metal, masonry, glass and most plastics
  • Suitable for both interior and exterior use; apply a UV-resistant coating for best results outdoors
  • Class-A fire rated when sprayed up to six inches wide x one inch thick (not intended for insulating applications beyond six inches)
  • Tack-free in 10 minutes, cuttable in 1–2 hours, and fully cured in 24 hours
  • Can be painted, stained, or sanded for a finished look
