Asked by: Anonymous
this product is listed a water resistance, so as long as you don't have a flood this should work fine.

Can this product be used to seal area behind electrical switch plates

My log cabin has many outside wall outlet and switch plates. I have cold air coming in from behind the covers. Can this foam be used to fill the void behind the electrical outlets and covers

Does this dry rock-hard?

I need a foam that will act like a seal and one that I can put a hook into which will be permanent and strong enough to hang. Yes, it's an art project. Think of a picture which I need to put a foam across the back to hide the tape, wires, glues that hold together the montage of mementoes on the front of the picture. Then I need to be able to put a picture hanger in the foam which will be permanent and I can use to hang the picture. Would this stuff work? If not, any ideas? I thought there might be something in car repair that might work, but what? Thank yoU!
Asked by: Mayran
Dear Mayran: If you are still working on this art project, I hope you did not try Great Stuff! The cured foam is light and has very little strength. Great Stuff also expands quickly and would create a lumpy, uneven surface. Not knowing how your art piece is constructed, it would be better to attach a piece of wood to the back to mount the picture hanger -- attached with screws or epoxy. To hide the tape, wire etc., I would mount the piece in a deep frame with a backing board. I hope this is helpful, Mark

Does this have the same formulation of foam as the bright orange Great Stuff Fireblock 16 oz cans with the straws?

I notice that this foam is described as being orange and also having a "US fireblock rating." It makes me wonder if its the same formulation as this product: http://www.homedepot.com/p/GREAT-STUFF-Fireblock-Insulating-Foam-Sealant-16-oz-345372/202023037
Asked by: DanFrontier
Dear Dan: The "Fireblock" version of Great Stuff does not include any fire proofing ingredients. All Great Stuff products will ignite at just 240 degrees F -- significantly lower than the ignition temperature for wood studs. In other words, Great Stuff Fireblock will catch fire before your wood does. The "Fireblock" label refers to the foam's ability to block smoke. It will not block the spread of fire, as the DOW rep incorrectly noted above. The key advantage of the large 24 ounce 'Pro' cans is improved output with a Pro gun vs the plastic straw. Justin Fink at Fine Homebuilding published a detailed study, and here are the numbers: Gun yield: 83 cubic inches per ounce Straw yield: 69 cubic inches per ounce Most important, spritzing the expanding foam with water boosted the yield by 73% (gun) to 92% (straw). The numbers above include this water treatment. Great Stuff foam requires water to cure, and pulls water vapor from the air. A light spritz of water improves the yield, accelerates the cure and reduces voids in the cured foam. I hope this is helpful. Mark

24 oz. Gaps and Cracks Insulating Foam Sealant is rated 4.4 out of 5 by 48.
Rated 4 out of 5 by from 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.

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.

The insulating was very easy to use. i used it to fill cracks and crevices inside and outside of my home. I purchased the gun along with the foam to make it easier to get in to tight places .

Rated 5 out of 5 by from Pro Formula is Better than Regular Great Stuff This is not just the regular Great Stuff, this is a completely different formula. It sets up in minutes, not hours, and you seem to get a lot more per can than the direct ounce comparison would net. I can go farther with one 24 ounce can of Great Stuff Pro than I can go with two 16 ounce cans of regular Great Stuff. I don't know why, but that is what I have been experiencing. Plus it expands most of the way right off the bat, so what you see is what you get none of the half filling the cavity and hoping/waiting that it will expand correctly. I had always previously just used the regular cans of material, due to them being cheaper per ounce, until I needed to seal against a ceiling. Normal cans don't go "up." (I tried using plastic tubing on straws but they would flow unbearably slow through the tubing. Works ok for a one time deal.) I will never go back to the normal Great Stuff cans. If you don't want to buy the gun, you can find the Pro formula in straw cans. I normally don't write reviews, but this product has truely exceeded my expectations.

Rated 4 out of 5 by from Cost per use makes this the winner Of course this is more per ounce than the 20 ounce "grenade" cans ( pull pin thrown into wall and run installation) but if you want to control the size of the bead and actually put foam only on the project ( not your hair and arms and any other surface in a 3' radius) then spend the extra money for this system. Cans last for 30 days on gun you can pinpoint place product and no more trying to recut the straw and losing a 1/2 can of foam because the little plastic nozzle broke.

Rated 5 out of 5 by from Great Stuff is Great Stuff Using the pro gun with great stuff is so easy. Cleanup is also easy with the pro gun cleaner. I highly recommend this product. The fact that I can reuse the same can over and over until I actually use all the product in the can is fantastic.
