Great StuffBig Gap Filler Insulating Foam Sealant with Quick Stop Straw, 16-Ounce 2-Pack

It took me a little bit of using it to know how to effectively spread it. But it worked great at filling up gap i had on my shed that birds where getting into. ONLY downside is that you must try to avoid it getting on your clothes. It's hard to get out and it stays for a while.

So....yeah it works great. However....the label on the back is highly misleading. Because I am a man, i do man things. I have used my hands to spread lots of things from elmers glue to jb weld. I figured this would go no differently. I was sadly mistaken. I was filling some cracks in my foundation and some of it was leaking out and spreading thicker in some areas. So I used three of my fingers to spread the material out into the cracks. This was the start of a long and painful experience.I noticed immediately that I couldn't simply rub my fingers together to "roll" the material to get it off, like you can with most glues. So I used my working hand to grasp the can and read the label on the back. "If you contact this on your skin, simply rinse with soap and water." Simple. Just rinse. So I headed jovially upstairs and washed my hands. When the water left the faucet, I noticed the horrifying reality of the water SIMPLY bouncing off this product. The soap SIMPLY helped smear the product further into my skin. I panicked. In my panicked stupor, I grabbed the closest thing to me that I could think of. A roll of paper towels. I ignorantly used the paper towels to try to grab the stuff off my fingers and pull. This made things 10x worse. Now I had this satanic cement on my hand AND the paper towel had created a horrid mesh of filth that was resistant to every product known to man.My next try was to use an old T shirt to try to wipe this stuff off my hands. The shirt stuck badly to my hand and I nearly had the same problem as the paper towels. I spent a minute yanking and finally got the towel off and saw the sad reality that all that pulling had made ZERO impact on removing any of the gunk. I started yelling for my wife and begged her to google this filth in order to find a solution....you know....since I couldn't use my phone for lack of having a second hand. She did so and told me that olive oil was said to relieve this issue. So I poured olive oil all over my hand and started scrubbing. This made only the slightest difference in my dilemma. I went and sat down on the couch dejectedly and turned on Season 5 Episode 4 of Dexter to make me feel better....although it didn't help much.The product had hardened at this point and I spent the next 4 hours picking away at my hand to get this stuff off. By the end of that time, I had managed to get off about 1/2 of it or so. I really needed to go to bed so I hit the shower and tried to wash my body with my brand new plastic hand. It only went okay. While I was in there, though, I noticed my wife's pumice stone. For the next 30 minutes, I sat under the water tearfully scraping away at what was left of my hand. After that 30 minutes or so, i had removed most of the offending substance and also a good portion of the skin on my hand. Success, kind of.The moral of the story is one that we all should know by the time we are 12 or so. Don't just willy nilly decide to do something like this without reading up on it first. Even if the label on the back does say that simple rinsing of water and soap will solve the issue. FML

Exactly as it is named: GREAT STUFF! And, it fills Big Gaps!

Good value

used this to insulate the cover for my well. Worked well. Maybe too well?

Shortly after receiving it, we are ordering another box. The stuff works like it says, the seller got the product here by the time he has stated. And the shipping and handling is very good, for the product came with no damage. Not one tear or even a dent in the box. I would recommend the seller, the handlers & shippers, and of course the product.

This does what it suppose to do, you just need to know how to handle it otherwise you WILL make a mess. Think of it as a whipcream can, that's how it operates. For gaps between floor/wall, put paint tape first, so it doesn't make a mess. For big holes around pipes it's not as a big deal. The stuff is sticky so once you get to areas you dont want, clean up is a bit tricky - make sure to wipe immediately.all in all it behaves exactly like how a whipecream can does exact you got a straw on top to direct the stream coming out to be more precise.

Wow! This stuff is legit. A little goes a long way. I purchased to fill gaps in my very old home and still had some left over. It was pretty easy to use. Whenever you open one though you should finish the project because I dont think you can pause and go back to a bottle you started on, as the material hardens. The drafts in my attic have ceased. The noose in my basement has been reduced. Great material. Do note that this stuff can get messy and is tough to get off if you get it somewhere you dont want it (got some on my finger nail and it took weeks to get fully off).

I like it because they are medium expansion, but they do leak out of the noseless parts....or it might be mine.

Really easy to handle. However; I'm glad that I practised before applying. It expands a lot. Easy to shape, cut off axcess. Dried fast and after overnight could not smell anything. 12 can is a great value.
