Great stuff!!!

I use this great stuff for multiple purposes. Fills gaps and cracks well. I also use this to build little dams with so I can pour self leveling.

Great for home projects and sealing gaps

This is a very useful product and has come in handy one more than one occassion. I have used this to seal concrete foundation cracks and most recently gaps in my wood eaves to prevent insects/birds from getting into the eave space. This is a great way to seal space between new builds or to buy some time for yourself to extend the life of other portions of your home.

Great Stuff Gaps & Cracks

This stuff is great. I have been working on my window air conditioning units. I have taken styrofoam and put around the inside of the air conditioners to block air that may come in and then around the outside just in the little cracks I have used this Great Stuff. Its wonderful for stealing those small air cracks, just wonderful.

Quick Fix for Gaps and Cracks

Great Stuff Gaps and Cracks Insulating Foam Sealant is a convenient and quick way to fill holes, cracks, and gaps in my home. I’ve been using this product for decades and love it. I used it today on a gap at the transition of our dog door to the sliding glass door that the trim left an open hole slowing air and bugs to enter our sunroom. I shook the van for 60 seconds, screwed on the finger trigger stem, and put a small amount of foam in the gap. I seconds it expanded and filled the hole. I allo...

Huge can huge foam

This is your typical expanding foam. It is messy (wear disposable gloves) but it does the job. I used it to seal around the penetrations in my crawl space. I like the size of the can and I was able to finish about 400 sq feet of crawl space with just one can. I also used it to seal the water penetrations between studs to keep the noise to a minimum.

Great stuff

Great stuff! Works perfectly for small holes. Filled gap then shaved off excess. Easy to use. Point pull and fill. No issues so far. I’ll see how long it last.

Sprays well and hardens quickly

I selected this product to fill some gaps around my dryer vent pipe. I didn't realize at the time that it wasn't for large voids, so I wasn't able to use it for that purpose. But I did spray some on cardboard as a test for review purposes. It sprayed very easily and the plastic nozzle provided plenty of control. The can says that it takes 8 hours to harden, but the foam was already quite firm when I checked it after 30 minutes. I could not find a way to clean out the nozzle, though, so I'm doubt...

Love Great stuff

Love Great Stuff products. We always look for the brand when buying foam barriers. The product does what it says. It fills the gaps to seal out the weather.

great stuff. brand name speaks for itself.

I love this stuff. I've sprayfoamed almost my entire garage (with a larger kit) but with an older house im always finding gaps and holes that allow air penetration. last winter our pipes froze several times in the garage. I was able to go back around and found a few small holes that were mostly on the block wall and get them sealed up tight! hopefully this solves my winter problems.
