Questions & Answers
What is the coverage area?
Asked by jesus November 5, 2020Never have used it to cover a large area but my guess is that if you were trying to cover 14 sq. ft. you would only be able to do about an inch, maybe 2 inches, of depth.
Where can these empty cans be recycled in Colorado?
Asked by scottygee August 26, 2020They do not need to be recycled, they are designed to be disposed in normal trash pickup.
Why doesn't this one expand more like the white one does? It takes so long to fill the rim joists with this orange one.
Asked by EM June 22, 2020The white is open cell, and is not fire block. I am pretty sure pro series means closed cell, and fire stop. Closed cell is also water resistant, but highly expansive, white is not water resistant, and wont crack windows.
Can this be used to fill the cracks in a (closed) fireplace flue?
Asked by Ralph June 4, 2020Hi, Ralph! Thanks for your question about DuPont™ Great Stuff Pro™ Gaps and Cracks Insulating Foam Sealant. Great Stuff™ Insulating Foam Sealant products should not be used around fireplaces or any other household area where it contacts heat conducting surfaces. Cured foam is combustible and may present a fire hazard if exposed to flame or temperatures above 240F (116°C).
Could this be used to fill a large gap under a concrete sidewalk?
Asked by jgotti May 14, 2020Yes, that is exactly what I used it for. Foam doesn’t expand a lot so plan on getting enough to fill your gap.
Can this be used as flotation in a boat.
Asked by Ddd May 10, 2020Dear DDD: No. It is difficult to form blocks or fill larger spaces with Great Stuff foam. The foam cures by pulling moisuture out of the air, so thicker sections must be filled with successive layers / lifts, with each layer allowed to cure before the next one is applied. It would be much easier to cut pieces of 2" XPS foam board to fit. Look for Foamular 250 at Home Depot. I hope this is helpful. Mark
