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

This product works well. I got it for a hole that was drilled during the cable installation. I followed the directions and it was simple to use. Be very careful to use gloves and not get on any clothes. Although I read the warning, I ignored the advice and have a small spot on my coat sleeve because of my “I’m careful and won’t get any on me” careless mindset.

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.

The foam does form a solid grip and water tight seal. I was looking for this installation ability. Unfortunately the bottle exploded on my most loved sweater and shoes at the application end. When I use super glue or caulk gel I do not have to wear a full smock and work boots. I wish the instructions had warned me more of the mess this stuff makes! After it dried I was able to trim and sand the splatters off, and it had a smooth window installation. Worth the price but needs more mess warnings!

It really expands quickly to fill large vertical gaps when you'd think it would just fall out but it doesn't. My back cement steps have shifted away from the house about 3 to 4 inches and squirrels had squeezed in the and were digging their wainup under the siding. I sealed the area during the day while they were out and that was that no more squirrels . The exterminator quoted $1450.00 so this saved me a bundle. AMAZON isn't uploading my pics for I'd share ..this product could have lots of uses for not alot of money

I used this to seal several holes in my house where mice were coming in from the street and garden. Foam is good and sealed the holes. My issue is that the spray did not come out smoothly from the straw dispenser and quickly clogged. It became a mess at the end and I was never able to use it other than the one application. I've used other brands and they definitely had better dispensing. But for the price, it served it's purpose but knocking a few stairs off for the mess created by the bad dispensing.

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!

I ordered this to fill a space in the walls and I wasn't aware of how MESSY this application was. After shaking this bottle up, it STILL came out watery. On the THIRD spray attempt, it then solidified as foam but there was still watery substance being sprayed out at the SAME TIME! IF YOU ARE NOT USING THIS PRODUCT THE SAME DAY, DON'T BUY. I made the mistake of "testing" the product on a certain area (so I didn't ruin my walls) to see the outcome before doing the entire area. Well, once this dries the tube (that disburses the product) hardens up and you CAN NOT use the rest of the bottle ANYMORE. Nope, you can't even replace the top/tube with another one... it's stuck/hardened together. And there is NO WAY to get all the product out the tube so it doesn't dry inside the tube. The other reviewers were 100% accurate on this one but I didn't listen :( I contacted Amazon to tell them about these issues and since this is a "hazardous" product you can NOT return it. NO REFUNDS ON THIS ITEM. So now I have a floor and wall to clean up and a FULL bottle of this foam that I can't even use... SMH. I would NOT... absolutely would NOT recommend this product.... especially not at this price (it's cheaper at Walmart and $3 for their brand). I wish someone wrote this review for me so I didn't have to waste my money, I hope this help you :/

I was only able to clog 2 holes. And the can was empty. Don’t buy the 8oz can unless u have 1 or 2 holes to clog up. Unfortunately I have more holes. Will purchase the 20z

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!!

Worked on a 3-4” gap. Need to use the whole can all at once. Any delay once stared will reduce the foam coming out of the can, even if you stop for a couple of minutes.

It worked very well Great save money and good qualityh

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!
