Rated 4.0 out of 5.0 by sf23103 works great, but plan well
Works great. Just trust that its going to expand like it says and don't spray too much. Its easy to trim excess when hard. Make sure you plan ahead as once the spray solidifies in the straw, thats it, you'll have to buy another.

Rated 3.0 out of 5.0 by TGRRAG One shot application but works well
This stuff takes a bit of getting used to, but works as advertised. The one thing to consider is it's a one shot application. Meaning, have what you intend to seal completely understood before you start using the product. This ins't like caulk where you can save the balance for later. It sprays out the consistency of whip cream then proceeds to expand about 3-to-1 in size before hardening. Be sure to let dry completely before applying caulk or paint over it.

Rated 5.0 out of 5.0 by Homeowner Nasty stuff to work with. Does a superb job.
Great for sealing air leak gaps. Plan ahead, since once you start, it's very difficult to stop and reuse the can later. You can only use this with the can upside down, which can make some spots difficult. Make sure you are wearing old clothes, gloves, and use lots of drop clothes. It takes practice to control the amount that comes out the tube. If you're doing a large project (like an entire cellar sill plate), I would highly recommend getting a gun.

Rated 5.0 out of 5.0 by Racine Great stuff!
So I bought this can on accident! I had a problem with mice in my new apartment. I intended on buying the pest control sealant but I couldn't find it. In turn,I bought this foam, tomcat bait and went to work. It's been nearly a week and no mice to date. I simply laced all cracks with the bait, foam, Brillo pads, and this method seems to Works great! Excellent product!

Rated 5.0 out of 5.0 by Vibrant77 Easy to use
As a DIY kinda gal, needed this to fill the gap around my bathroom pipe so that creepy crawlers and draft won't occur anymore.
Twist on nozzle, make sure your arm,eyes,hair is covered/protected..then spray away. Sprays and dries an ivory tone. Expands very quickly in humidity (shower steam). I got a smidgen on my finger. Used acetone/nail polish remover to take it off because it started to get tacky/sticky.
I didn't need to use even 1/4 can, and I didn't want the rest to go to waste. SO, I used the acetone to unclog the spray nozzle by pouring a few drops in both ends then tapping it gently to loosen the goo. I also cleaned the black opening on the can itself. Brand new, unclogged,ready for use again in the future. I also read on the web goof off works too if you don't nail polish remover.

Rated 5.0 out of 5.0 by BvilleBound Great solution to improve insulation and stop air flow
Hello all: We used Great Stuff foam on a number of projects, and it is a great solution to seal gaps and cracks, seal the edges and joints in XPS insulation board, fill the hard-to-get-to spaces around HVAC ducts, etc. Here are a few tips:
(1) Installation: Great Stuff is a one-component foam and cures by pulling water vapor out of the air. You can double the expansion by spritzing a little water on the surface before you spray the foam, and misting some more water on the foam after you apply it. Start by testing with a ball of foam on a piece of cardboard at your home / job site.
(2) Foam board: Great Stuff is ideal to seal the edges and joints in foam board, e.g. if you install XPS foam board from Home Depot in your walls or between the raters in your roof. A photo is attached of a recent project, where we installed XPS in the walls of a house on the Cape in Massachusetts, and sealed everything with Great Stuff.
(3) Windows and doors: Make sure you use the "Windows and Doors" version of Great Stuff to seal and insulate around windows and doors. The low expansion rate and flexibility of the cured foam are essential.
(4) Fireblocking and hot surfaces: Cured Great Stuff foam will ignite at 240 degrees F -- including the "Fireblock" version. This is significantly lower than the ignition point for wood studs. DO NOT install Great Stuff next to any hot surface, e.g. a furnace, hot HVAC ducts, canned ceiling lights, a fireplace or chimney, etc. Rock wool and 3M fireblock sealant should be used in hot areas; both are available at your Home Depot.
I hope this is helpful.

Rated 1.0 out of 5.0 by Cando Too messy and uncontrollable
Sprays out of can too fast and too powerful causing too much over pour so that it clumps up in places. You cannot apply this stuff evenly making the finish look very ugly. It also doesn't stick to surface fast enough so that it drops off ceiling application and also drips down the wall when applied vertically. As you can see in the picture, this stuff falls off the ceiling before it can be applied. This stuff must be applied only downward if using it too seal along edges and even then it fills up too fast. About all that it is good for is filling up large holes and big cracks. If it came out of the can slow and steady and would stick immediately, it would be a better product.

Rated 5.0 out of 5.0 by teachvt I am the spray foam queen
This stuff is a God send once you get the hang of it. I live in rural VT and have used this on an old mobile home and a 200 yearold cape. If I listed all the uses I've found for it, you'd stop reading because the list is too long. It came in very handy to fill 1-2 inch gaps between 200 yo outer planking, so that we did not have to ruin the history and waste good wood to cover it with plywood (see pics)
Messy? YOU BET- wear gloves and clothes you could throw away if needed. If it drips on you or anything else WAIT UNTIL IT DRIES then it usually picks right off. Ladies, even polish remover does not get this off your nails-wear gloves.
Expands too much-Yes, use common sense, and read the label, if you need a product to fill where that is an issue, this is not it. HOWEVER- if you need a flat surface where you have sprayed it, just trim it off with a hand saw, or any serrated tool. I've used a tiling trowel, and a kitchen knife, to name a few.
Using it overhead- get as high as you can, keep the can as vertical as possible and carefully bend the tube upward rather than laying the can horizontally. DON'T break the tube off or it will burst out all over you.
Reusing a partially full can- for short term, a day at the most, stick a nail in the tube right after you finish, galvanized nails will pull some dried product out with them so they are good. For long term- use a sheetrock crew and drill it in there, you will have to drill it back out, but it last for months.. Make sure your nozzle is tightly screwed onto the can or it will dry out there.
