Great Stuff 99108240 2 PK Smart Dispenser Sealant, Gray

Best Foam Ever NO CLOGGING Multi Use Sprayer! Great for plugging holes /cracks to keep out vermin! Due to Human Error I always manage to get it on my skin or clothing somehow! Not easy to remove from skin, clothing, or hair etc. Strongly suggest using gloves!

Used this in a crawlspace the seal around waste plumbing and such. I first put some copper mesh around the openings and then squirted this stuff in there. On my back with limited working space it worked but not without a sticky gooey mess. Nobody can see it so that wasn't a problem. Very important to wear disposable gloves or you will get this stuff all over you. Wear some old clothes as well if in an awkward position like I was. As for repelling rodents, I don't know if it will or not. The copper mesh will keep anything from biting through though.

It works great. I used it sealing small cracks in door frames, and between siding and concrete. Like great inside, although the color isn't gray when it dries outside, it dries yellow but its paintable so that's okay

So far, so good. Was having a rat infestation behind a wall. Could hear those little critters scratching and carrying on all night. I thought they might chew through the wall and kill me in my sleep. So I got some of this foam stuff and some steel wool and filled the gaps in the garage. Works great. I can sleep now. Will buy again for other projects.

Nice new start and stop dispenser. False advertising, rats will chew through the foam if there is no metal reinforcement. I’ve been doing rodent exclusions for twenty five years.

2 pack is the perfect quantity for my project. Used in my new outdoor shed to help keep the chipmunks out. Worked to keep the carpenter bees from chewing up my soffits too! Love that I can reuse it and that it didnt leak everywhere. Truly Great Stuff!

This stuff is not fun to work with. Put yourself in very old clothes when using it because if it gets on your clothes, it is never coming off. Please wear gloves when handling it because I did not and it dried on my hands similar to how crazy glue feels. I literally had to sit and pick off specks of it from my skin which took forever. Soap, acetone, alcohol -- none of these things will do anything to get it off. I also wanted it to dry a gray color which is why I bought this particular brand that stated it was gray, but it dried a very bright orangey yellow color. They should have more warnings on this stuff.

This product worked great-sprayed it in spaces in garage to keep unwanted pests out. Super sticky so don't get it on anything you want to keep. I ruined a pair of shoes and my pants using this. Get extra gloves to use as one pair won't be enough when working with this. I used the whole can at one time. Messy and not easy to clean if you get it on other things besides where you need it. But expands really great and lasts! Color was Grey when dried (but turned yellow later).
