What is the coverage area?

Asked by jesus November 5, 2020

Answer

Never 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?

They 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.

The 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, 2020

Answer

Hi, 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?

Answers

Yes, 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, 2020

Answers

Dear 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

ONE TIME USE PRODUCT!
The Great Stuff product works fine for insulating doors and windows, however, remember that Great Stuff is a ONE TIME use product. After initial use, Great Stuff foam hardens in the can, and can not be used again. Therefore, I would recommend Great Stuff as long as you DON'T intend to use the can at a later date. USE the can ONE TIME and throw it away!

Response from GREAT STUFF & DuPontNov 3, 2020
Hello, Chuck - Thanks for sharing about using Great Stuff Pro™ Gaps & Cracks Insulating Foam Sealant. We apologize for any inconvenience you have experienced. The Great Stuff Pro™ Insulating Foam Sealant products can be used with the dispensing straw or with a Great Stuff Pro™ Dispensing Gun. Using the gun does allow the can to be used for up to 30 days after initial use if the flow control screw is fully tightened for storage.

Reusable, greater volume and less expansion than the single-use cans. I highly recommend using this and the gun if you have a fair amount of filling to do. Personally I have found that I need to use these over a period of time and the gun allows me to do so. Using this in conjunction with roughly fit pieces of polyiso or EPS foam board insulation is an economical and relatively environmentally friendly method of insulating basement joist bays over using spray foam froth packs.

It's easy to work with especially with the pro 14 dispensing gun. Very little mess. It expands but much less than the big gap filler. It's also fire blocking. I wished the company had a long flexible tube that had the quick stop straw on the end for the hard to reach places. Tubing without a shutoff on the end is much more messy.

Pro can is better
This "pro" can works with the applicator gun, it is well worth the 50 dollars. I was insulating overhead and went through 3 cans of the regular foam on less than 10% of the ceiling and made an incredible mess. With the gun and this larger can i was able to do the rest of the ceiling with only 2 of these. Made it well worth the added cost. It doesn't seem to expand as much as the cheaper cans, and it is bright orange instead of the yellow.

The product is great "GREAT STUFF 24oz" . I will never go back to the $4 one time use can. But I also will likely buy in bulk online for <$10 per can
