Red Devil Foam and Fill Off White Expanding Foam Sealant for Small Gaps 12 oz

i am fixing an old home and the door had a hole in it. i put this foam in the hole, let it dry and it worked amazing.

I had an area where air was coming in from a crawlspace beneath the den. This Red Devil foam did a nice job filling in the opening. This foam applies easily, and has no odor. It stays where you point the nozzle, and hardens after a few hours. I like this product & will purchase it again.

I discovered Red Devil Foam and Fill Small Gap Expanding Foam Sealant at the exact right time. Just as the weather started to get colder, I noticed a gap under the outdoor siding by my kitchen door. In the past, this kind of crack was all that mice needed to sneak inside, and I never want to go through that again. Hopefully I won't have to thanks to Red Devil Foam and Fill. It was so easy to fill the crack with the expanding insulating foam, I could hardly believe it. Using the included nozzle, I went around the perimeter of my house and filled in any holes or cracks that I saw. The 12 oz. can contains a whole lot of foam! I love that this product is environmentally safe as well as versatile-- it can be sanded, painted or stained if desired, but I'm fine with it as is. This is an effective, easy-to-use product, and I recommend it highly.

Retired from the phone company, where we used foam sealer on a regular basis, I had high standards for this product, and it definitely delivered. Many things to like about this product, first being the ability to control a very slow bead of foam. This is critical because if you don't have control of the bead it'll seep out too fast, expand way beyond your intentions and create a mess. Due to a very good mixture its' expansion is steady, full but not too fast and expansive as to be unpredictable. I was filling in under the sink by the rim of the trap (pictured), also along both left and right corners as there were gaps from 1/2 inch to 1/16th. Red Devil Foam Sealant did the job and dried fairly quickly so I could trim it with a razor knife. I wound up going around the house and using the whole can, it goes a long way, again due to the superior control of the nozzle output. This is a very good product and I highly recommend it.

The Red Devil Foam and Fill Small Gap Expanding Foam Sealant works great in new construction or to touch up gaps in newer or older homes when needed. It is easy to apply using the included applicator. You must turn the can upside down to apply when you pull the trigger after shaking the can well. This is a minimally expanding foam, but it does expand so you need to test it a little as you first use it. After it sets up, around six hours, you can trim off some excess if necessary. I have used these foam fillers before so I have learned to fill spaces or holes only about half way to allow for expansion. You can add more if needed. I use this for a lot of different applications and I have even used it to plug holes in some of my oak tree limbs that have hollowed out to prevent insects or water from entering. While the manufacturer doesn't list this as a use for this product it has worked well for me since it has some give to it as the tree grows.

I was surprised that this would fill pretty thick gaps seems how it stated, up to 1 inch gaps. It was easy to use and a I didn't have any messes using it. There were no leaks in the nozzle or anything. The can didn't last very long and didn't cover a lot of space but it got the job don't for me. I would say the only thing I didn't like is that you can't reuse it after it dries in the nozzle.

Once you spray this foam into a crack, it foams up (expands) into the hole/crack and becomes very sticky once it settles and expands. It's fairly easy to wipe excess but you have to be quick and warm/hot cloth works best. Comes with an extended nozzle to get into cracks easily. Gave 4 stars because it gets very sticky when setting and difficult to wipe away excess but that's expected.

I use this stuff for almost everything. It works great for gaps that appear in your home's foundation. I've used it on my shed to fill the gaps where hornets wanted to get in. It works great around the door casing. A little goes a long way. I love that I can shave off any spillage and easily clean up a spot that overflowed. I think of it as caulk for big holes. Once you open that can to use it. You better have a use for most of the can. Unless you can clean up the application straw, you won't be using the can a second time.

I have used this type of product in the past. Tried the Red Devil foam for small spaces, hoping for different results. Sealed a space on an AC window install. It rained heavy last night here in SoCal and no water leaks noted on that window. Sealed a couple of small holes in an interior door. Also worked as intended. Easy to apply and once product dries simple to trim and finish. However, this product is very messy. This is a single use can. If left after use, foam will continue to ooze out and accumulate a huge glob. Once dried it is easy to remove from a cardboard box. Removing stem from nozzle will result in a huge mess. Removing from skin or clothing is difficult at best. It takes some effort. If a homeowner intends to use have many old rags handy and they are going right into the trash as they will be unusable after. Can't recommend this product, unless it is intended for full use of product.

This is spray foam, which we usually use for jobs that don't require "craftsmanship." So I will say that this expands well (too well, if you're not careful) and dries fast, so it's easy to clean up if you do spray too much (after waiting a bit). But, after the first use (and we rarely have jobs where we'd need the whole can for a single job), it gets harder to spray because of clogging. And spraying too much will make it take longer to dry, so you have to be more careful how you spray if you need a lot. So - it's okay, but other brands have been better.
