DuPont releases Great Stuff Wide Spray foam sealant
New insulating spray can seal large gaps, irregular surfaces and hard-to-reach spaces.
DuPont Performance Building Solutions has introduced its Great Stuff Wide Spray Foam Sealant, a new broad-coverage spray foam ideal for air sealing seams, joints, large gaps, irregular surfaces and hard-to-reach spaces.
This one-component foam sealant expands up to one inch, creating a durable, airtight and weather-resistant seal, per the company. Designed for fast application, it adheres to both vertical and horizontal surfaces without sagging. With a formula that requires no complex setup, mixing, coveralls or respirators, Great Stuff Wide Spray can streamline the process.
“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. “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 4-inch wide band. The kit also comes with four nozzles that allow users to tackle a variety of applications, including two white cone nozzles, spraying up to 4 inches wide for more precise sealing in tight spaces and two blue fan nozzles, spraying up to 6 inches wide for broad coverage from a distance.
The fan spray is ideal 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, per the company.
Great Stuff Wide Spray offers additional features, including:
- 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 6 inches wide x 1 inch thick (not intended for insulating applications beyond 6 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.
