Works Great
Work great and is less expensive than the more well known brand. I sprayed water on surfaces so the stuff has extra moisture to help cure. Work excellent!!

Good stopper
Works great. Needed to seal my foundation where it has pulled away from flooring. This worked great to stop rain from entering

Good for leaksâ¦so far!
I love this stuff. It will expand a decent size â I used it to cover some cracks between my gutter and my shed (didnât want leaking), and itâs holding up fine. It does looks like creamed butter when it comes out but it sorta turns blueberry muffin yellow after a while. This didnât bother me but if youâre looking for something that stays light-colored, this isnât it. If you put it on metal, you can pretty much pry it off with a screw driver â Iâve done this before, as I had used it to cover some screw holes in my metal carport roof. I didnât like how it ended up looking on that project â I sprayed too much and it was like a tennis ball over the screw⦠but I WAS able to use a razor blade to cut out the section I wanted to stay on the screws and remove the rest with the blade so now it looks less jinky. Itâs easy to use â itâs also easy to over spray. I bet if you wanted you could put some painters tape down for a better more controlled outcomeâ¦but, I did not think of that ahead of time and it may not even work THAT well, since it puffs out as much as itâs going to puff. It kinda looks like merengueâ¦but yeah, it worked for my house hold leak(s) pretty well so far. I donât know if it matters but I live in Los Angeles where itâs mostly warm and sunny soâ¦it *might* not be as successful for you if youâre in a REALLY wet or cold environment. Iâd buy it again.

Gets the job done!
Works great and it’s a little cheaper than other products that do the same thing. Just remember once you use it one time it won’t work anymore and so make sure to fill in any cracks or areas that need it the first time around.

Didn’t Work For Me
Followedthe specific instructions on how to use this. For some reason I was unable to get the product out of the can. Not happy with the results

Great for filling hole for secure flagpole.
Easy to use. Fills hole fast and holds flagpole in place.

Works as expected
Terry B. –
Not enough capacity. But easy to use.
It was very easy to use. The problem is the product did not have a lot of insulation inside of it. I went through three cans pretty quickly. I had to order some more cans of another product.

I had hornet hiding in my house so I used this to block all their holes they made and I successfully destroyed the infestation with a can of this bad boy, it filled those holes faster than they could try and sting me. I definitely recommend for hornet killing, and I’m sure it’s cool for Insulating and all that.

Used this on the air conditioner and gas line passage into the house. One squirt later, foam was expanding outside the passage. Still have a lot of product left for those odd jobs.
Lynn –
I used it for cracks in my garage where bugs kept going in and out of, and in between bricks, works great, do remember to only fill cracks halfway though since this stuff really does expand
EJF –
