Rated 5.0 out of 5.0 by More than one use for this "Great Stuff" Not your typical use of this product but it's great for Halloween décor. I've used it for years to create vines and other Halloween props. Easy to use and last forever. October 6, 2015
Rated 4.0 out of 5.0 by How to re-use without throwing out after first use When I tried to re-use the can after one week, the built in straw broke off. I felt bad throwing out the can since it was still full, so I kept it for more than a week. Meanwhile i realized that the STRAW from DAP Tex foam sealant (that I also bought from Hdepot) could fit in the hole where the built-in straw was. SO I cleaned the hole and inserted the straw from DAP Tex and when I pushed the base aside to trigger the outflow of the foam, out came the foam !! But make sure to shake the can for a full minute ! SO DONT THROW OUT AFTER FIRST USE, get the STRAW FROM DAP TEX and you can fully use all the contents as I did! Note, it may be a little hard pushing the base of the straw-hole which triggers the outflow of the foam but if you wear gloves to minimize the pain, you can use up the entire can as i did !

Rated 5.0 out of 5.0 by It really is "Great Stuff" Worked like a champ. sealed off the T@G cathedral ceiling from the attic. We were losing so much air into the attic around the chimney. The gaps were huge and this stuff worked better then expected. May 20, 2015
Rated 5.0 out of 5.0 by Problem fixer - add to duct tape & bailing wire accolades Once used to how MUCH it fills/expands it fixes everything around here: AC duct holes Roof deck holes Poorly flashed windows/doors, outside & in Masonry holes Penetrations in wall, e.g. wires, pipes, etc. Yellowjacket/African bee nests carved out of/into vegetation, soils Foundation gaps allowing water in Burrowing pests cave openings Insulation between joists, studs, around ducts, storage sheds more .....

Rated 5.0 out of 5.0 by Does the job It works great! But, if you drill a hole to add the product between drywall and the outside wall of your house, be ready to very quickly plug the hole when you remove the tube. if you don't plug it, since the product expands, it will ooze out the the hole. Oh, what a mess!! But, I was ready when I did the second hole and it was not a problem. September 8, 2015
Rated 5.0 out of 5.0 by Works Great!! I bought this product to fill a crack outside between my fireplace and siding where bees decided to make a nest. This morning the bees were unable to get in, so hopefully they will go away. My only recommendation is to wear gloves while using this. I got a lot of it on my hands, and it became an unwashable sticky paste that I had to use nailpolish remover to get off. It got rid of the stickiness, but I still have caked on insulation on my fingers this morning that will eventually come off. Also, make sure you clean out the plastic application tube. After it dried out, I was able to use a shishkabob stick and toothpicks to push it out. August 6, 2014
Rated 4.0 out of 5.0 by Excellent product I used this stuff to add extra support for my shower floor repair. March 15, 2015
Rated 5.0 out of 5.0 by Works as intended Works great for big cracks that need to be sealed. Pain to get off fingers, has to wear off. Wear gloves! September 12, 2015
