20 oz Big Gap Filler Insulating Foam Sealant ( package may vary )

This works really well for filling good sized gaps and protecting against wind and drafts, rodents and pests from around openings into houses and sheds. It's easy to use if you follow instructions, and works really well. The only downside for me was that using a part of a can resulted in difficulty using any remainder at a later time as the spray nozzle was blocked by some of the dried spray foam.

I used this stuff to seal and attach one side of a pop up tent to the exterior of the building. Works great to keep rain and ac drips off us and holds the tent in place. Also used it to seal the bottom of a fence where water would seep.

This stuff worked well for what I needed it. I had space between boards and roofing of a coop and chicken run that mainly I didn’t want wasp to be able to get in and I was able to pretty quickly and easily spray into the holes and fill them. It expands after spraying which is ok and can be good but when you don’t want to leave a gap you just fill it initially and deal with the excess after it expands. I just took a knife and made it look a little cleaner which really didn’t take long to do either. I don’t think I have to worry about anything getting in those gaps now whether wasp or any other animal.

I give it five stars because it works to fill gaps but if you add too much expands too wide and it opens the Gap more so be careful how much you use up with it

It really does the job well I needed it for two large holes and I still have a lit in the can. Well worth the money spent

I bought this to sound proof my extremely hollow door that was separating my bedroomFrom the hallway where all my other roommates rooms are located. Put 2 holes in the top of the door and sprayer both cans into the door. They both filled up my hollow door and made my room just that much more sound proofed. 5 stars all around

Stuff is sticky, wear gloves and old clothes. Don't think that you are going to be careful and it won't get on you. It will. Once it hardens, you can't get it off. When it's still wet, you can wipe if off if you use Acetone. But be careful with acetone, it will sips through you skin and it's toxic.Sound proofing is a dubious claim, I tried it on a pvc sewage line, unless you can have it encased from head to toe, and all around, you will still hear the flush. I have tried. It does not work. Even if you open up the walls, the pipe is about the same width of the cavities, you have no space for the foam.The stuff will expand to 5-6X, you get more with the 20 oz for the same 12 oz price at the big box store.You can close the tip and reuse it later, i would say within a short time only. Or you should submerge the plastic dispenser in acetone.Wear gloves!

Product worked as described and filled small/large gaps easily. I’d think of it as a one time use can so make sure you have all the spots you need to use it picked out. I went back a few days later and it wouldn’t spray but there wasn’t much left so no biggie.
