Red Devil 0912 Foam & Fill Large Gaps & Cracks Expanding Polyurethane Sealant, 20 oz., Off-White, Pack of 1

Used to fix a fiberglass shower pan, worked great as a support and easy to clean. Would buy again.Top rated for a reason.

Not its recommended use necessarily, but a hollow metal leg on our futon broke, and glue and other components weren't working to fix it, but filling the leg with this sealant and allowing it to set did the trick!

in my shed we had a great big huge rat hole. It would be better to fill in the hole with the stuff. It worked very well but the only shocker of it is it’s a one time use only he try to use it for the second time it will not work

Works well

I usually use another brand with a yellow cap. It’s only a couple bucks more but this had such good reviews I figured a couple bucks for essentially the sane thing. I received my 6 pack thinking, I can use this several times. The can is pretty small, so I figured at least I wouldn’t waste it like the larger can. Almost always end up with a can that is half empty. Except these cans are literally mere seconds worth of spray. I needed to fill a hole around pipes where plumbers had just cut my wall open. It required 3 cans of this, the other brand would have still had foam left. So ultimately each can is a couple bucks cheaper but if you need 3 or 6 to equal the other brand, then they cost 4 times the cost of the other brand can. Even with wasting half a can as a prospect, it’s still a much wiser buy than these are.So that issue aside, if you have a small area, then these work. The foam expands a lot, but not terribly fast. I had to walk away and come back later. It had expanded, maybe even more than that other brand. The foam was dense, and tough. It will do what I needed, I just wish I had known the actual content amount. I do have 3 cans left and now that I know how much they can do, I can use them on smaller jobs while I use the large cans from the other manufacturer for my larger jobs. Overall, terrible value for the amount gotten. Hopefully my review can help others know this going in so they can be sure they get what will fulfill their needs.

Awesome

It got everywhere except the cracks it needed to be. There was little adhesion, so half of it kept falling out from where it was sprayed. There is just a tiny portion where it needs to be - 3/4 of the can is all over elsewhere. It was sticky enough however, that when it backfired and the top exploded off, it stuck on my face, hair, ruined my clothes, and made a gigantic mess. I never thought a foam can could cause so much damage. When the cap came off and the foam kept spraying out, it damaged my eye, my outfit, and the surfaces of the room and exterior building. Will never buy from this company again! A 2 minute fill job has just turned into throwing clothes out, cutting part of my hair, repairing damaged paint on the building, cleaning the tiled floors, and scraping the exterior doorway. I started the clean up process 40 mins ago. It’s still not completely clean. NIGHTMARE!!!

My decoy broke. This fixed it enough to use. This and duct tape, or should I call it duck tape since it was a duck decoy. It floats now and that's what matters.

I bought this to fill in a very large gap in my front door. I'm a senior woman and am not handy in the least but this product is so easy to use and it does an amazing job. I rinse the straw part out with very warm water immediately after using it and this enables me to use it again. If you don't rinse it out then the foam will clog and harden in the straw. If you have any gaps this product will do the job and it volumes up quickly so don't overfill but it's also easy to shave down with a spatula or knife. I'm glad I got a really good product!!

I read the directions after using it and the tube was clogged, you'll need paint thinner to remove the goo.

I used this to fix a Towel hanger that fell off a drywall. The towel hanger was initially fixed on a drywall that had no stud, after watching a few YouTube videos, I decided to go ahead with this product, the towel hanger is back on the wall and it is strong enough to hold a few towels.

Didn't seam like a lot in the can

I bought this to fill in a few cracks that were sleeping in cold air into my house.I'm not very handy, but this was so simple to use and did the job right!
