super sticky, and foams up more than expected. Really fills all those cracks and crevices. Can be razor bladed smooth and painted to match the surrounding material if you wish

Good stuff but very difficult to clean up.

Great stuff and a larger can than is available at the competition... and tha applicator nozzle is better too.

Required by code because it is orange. Tried to burn it and it don't burn so it works like it is suppose to.

Worked great, came out faster than normal Great Stuff (red can). Go quick when applying this.

I used this in electrical boxes to seal them prior to termite work. This was required by our termite company to assure the lethal gas did not seep into other buildings. I watched videos prior to using and these were very helpful. I used a nail to stop up the nozzle after using it so I was able to use it a 2nd time. Videos are very helpful!

Does what it says on the can. Great for air sealing around electrical connections in an attic.

Most of them weren’t good, they turned into liquid instead of foam.

Not enough propellant in can to use entire product. Very wasteful.

Not only will this foam not block fires, it will burn faster and easier than all of the other building materials in your house (that I can think of). One of the pictures has this being used around an electrical box. That is a terrible idea, don't do it. A small electrical failure in an outlet could cause a fire within seconds if this foam ignites around the box. Watch videos on Youtube or try burning a piece of this foam for yourself. Dow Dupont is responsible for tons of fire damage fueled by this foam. Even if it "meets code" in your area, don't use it. I used fire barrier caulk as I could not get it to ignite no matter how long I held a lighter to it. It's more expensive, it's messier, and more difficult to clean up, but the peace of mind is worth the inconvenience and extra cost.

Exactly what I needed for my home construction project.

Used it where someone did not, very easy to use, did not use the off nozzle in it neacused the whole can.. Still need a bit more

It worked great for what I needed. I am redoing my chimney and used it to cover some open spots. Dried fast and cleaned off what I didn't need. Would suggest it to anyone.

Worked well to seal the insulating covers over my can lighting in the attic. It does not expand as much as I thought it would, but there may be some cooler temperatures at the time of install that had something to do with this.? As far as being fire retardant, I am not sure yet how well that is, I plan to run my own test on some sample foam left over on some drywall in the garage under controlled conditions.
