GREAT STUFF Pond & Stone 12 oz Insulating Foam Sealant

Pros Absolutely adore great stuff. I’ve never used it in construction or plumbing settings, but it works great in aquariums/terrariums! I made the base of a terrarium background with it (WIP) and it held on well!! You can cut it off with a blade very easily, as well as just pull and scrape with your fingers. Very good at being waterproof though!! Cons If you don’t use the whole can in one sitting, it’s really hard to get the rest out (in my experience). I had to get a whole new nozzle just to use a can that was half empty, and even then it struggled. The insides were all dry foamed up! But if you use it all, great product. (And maybe I’m just dumb and didn’t do the reuse part right lol)

Didn’t get this product

Didn't deliver on it's promises. Foam only partially expanded and there was not enough in the one can to fill a relatively small hole in a tree which was what the intended use was. Disappointing and won't buy again.

I love this Stuff! It solves so many problems for me. I have used it to build rock and concrete flower beds, stopped up holes, turned water, etc. Just a word here about "rat/mouse" resistant blow foam, which is quite expensive, compared to this product or regular Great Stuff - If you really want to keep rodents out, save yourself time and money by using steel wool every time you find an access. Put the steel wool in the hole and spray the foam into it and the hole. I learned that the hard way. This product has a "moisture cure" feature so you can apply it to damp surfaces. It is super easy to remove, and the best thing I have found to cut it is a hacksaw blade. It gives me flexibility to put things where I need them to be now, knowing I can easily move them later. I keep a couple cans on hand just in case. NOTE: Shaking the can is very important, critical actually, and should be done vigorously for several minutes. Also, I set the cans where their contents can get warm before I shake them. It can be cold outside but if the contents are warm and well-shaken you can dispense the entire can. By cold, I mean around 35 degrees Fahrenheit. ACETONE (Ladies, think nail polish remover, as most removers and contain acetone.) will clean it off your skin, just wash and apply lotion afterwards.

Easy to use, seals well.
