Rated 4.0 out of 5.0 by Maggie It works, It really works
Love this "STUFF" works great and repairs literally last for years. I've used it to fill in large gaps where stucco has crumbled on the outside of my house. Keeps out weather, moisture, critters etc. until I can get to a more permanent repair. Easy and effective temporary or permanent repair. Only draw back is the nozzle. The newest renovation is a sliding cap on the end of the nozzle which restricts the flow. It caused so much pressure in the length of the nozzle that it snapped the entire nozzle right off the connection on top of the can. Look for the open ended nozzle. Store will exchange with no problem. Clean up is messy but if you clean the nozzle and straw well, you can get a 2nd and 3rd use from the can. Definitely wear latex gloves. This stuff is made to stick tight and your fingers are no exception.

Rated 4.0 out of 5.0 by Abi2012 Very similar to regular Great Stuff
I needed to fill a gap of over 1 inch wide and 14-foot long. One can was enough, though I had anticipated it would be too much. As it turned out, the Big Gap filler was not substantially different than the regular Great Stuff in that it didn't expand as much as I expected. Therefore, I had to double back and re-fill many remaining gaps. In the end, it worked for my application, but its performance did not match the description on the can. In the future, I'll just buy regular Great Stuff because it seems to be more dense (i.e., smaller bubbles in the foam) when cured.
By the way, I've seen complaints about GreatStuff regarding how messy it is when you try to work it/shape it after applying it. GreatStuff is not caulk and should never be touched after application. Trim any excess only after it is fully cured (note: the inside can remain sticky after the outside is firm to the touch, so be patient).

The product does what it claims it should do and gets into the smallest areas to make a seal against drafts & insulates as the company claims - glad we chose this product for our project!

Rated 5.0 out of 5.0 by Alldatoys66 Fill big gaps
I bought the big gap filler when installing styro/ aggregate panels around my foundation. I needed something to fill the gaps since the basement walls are not straight. The walls bow in so there is a larger gap at the bottom than the top.
After installing the panel, I filled the backside with foam and braced until set. This held the panel in place and level. Upon backfilling with dirt, there was no movement. Even when the ground is saturated with rain water the panels have not bowed at all since about a foot and a half of the 2'x4' panel is buried.
I highly recommend this product.
