Great StuffBig Gap Filler | Insulating Foam Sealant, 20 oz. – Cream (12 Pack)

I watched some YouTube videos, using the product to reinforce sunken concrete on a walkway. Use it under a portion of our driveway after sprinkler erosion. It filled the gaps and has kept the concrete from moving. It did not, however lift the concrete as I anticipated it wouldn’t.

The only brand in a can I use because it sticks to vertical surfaces so well. I have an older wood home that I'm rebuilding a little at a time, and use this stuff just about everywhere, The only complaint I have is that it took two weeks to get here, .... don't understand that because orders usually arrive much quicker. I wish each can was around 5 dollars instead of 9.

good product for intended purpose

Best tip I can give anyone using this type of stuff is: If you drop a blob on anything (other than your skin) let it dry before trying to remove it. Definitly do not try to wipe it up before it dries. If you were unlucky enough to get it on your skin.. or in your hair then about the only thing you can do is use acetone as soon as possible followed by lotsa warm soapy water. You can let it dry on your skin but it will be very difficult to remove. Good luck!

Wish the cans were bigger. We insulated a whole house and used a lot of cans. Love the fact that you get an R rating of 6.5 per inch of insulation.

Used to refoam an indoor spa. Works as described

Out of sell by date was over a year old didn't want to come out of cans and nozzles broke on most of them
