Sprayman Spraycoat Fire Rated Spray Foam Insulation 480 Sq.Ft - R-Value (11.32 / 2in) Closed Cell Polyurethane Foam Sealant for Heat & Noise Insulation - Gun & Cleaner NOT Included - 27.1 oz, 24 Pack

This stuff works so well and is very easy to get the hang of installing. We've been spraying it on our metal cabin walls. Mist the walls with water before spraying, otherwise the foam will not adhere correctly. It will stick, but the powerful gun will cause air to push through on the parts that weren't stuck all the way. We've sprayed the walls when they were hot, in the early evening and cool in the late evening, after the sun has gone down. The dry time was about the same. Do be careful if you have respiratory issues. Definitely wear a mask, otherwise it will cause irritation in your lungs and throat. I have asthma and woke up in the night a few times having to breathe through my mouth because of the irritation from spraying. Cleanup afterwards is not so tedious. If anything is spilled or fell off the gun, just wait for it to dry and kinda chip it away. We also live next to a train, and after spraying the wall closer to the tracks, it didnt wake me up at all! So it definitely blocked out those sounds. The insulation however, is nice. Filling in gaps, for sure.

Works every time.

Great product

Worked out good for sealing and insulating a dormer we repaired.Opted for this vs fiberglass batting

This does not cover much area. So expensive. Regular roll insulation is a cheap solution.

easy & fast to use! tricky for overhead spraying, wish canister tilted away from user.

I purchased 2 full 12 can kits with guns, and one extra 12 pack. I planned to insulate a metal building roof. One of the sets of 12 cans was completely solid. Unusable as the product was either too old or not forumulated right. When you buy these, immediately open and shake them. You should hear the contents moving inside. If you don't, return them.Very little by way of instruction. Most of this is on the can. One thing I noticed was that best results are when you move quickly and use the full trigger...wide open. I used the "A" tip for a fan pattern left and right.One thing I noticed is that there is a limit to the angle that you can spray upwards. Since the can sits upside down on the gun, you cannot tilt too much to point straight up or you'll just release propellant. So I ended up spraying the ceiling at a 60 degree angle. Not too bad, but not ideal. I started to get the hang of it.The biggest surprise was that halfway thru this job, the color of the foam changed! Now I have white and purple foam! Wild! Perhaps I should care, but the OCD part of me will pull my hair out, so now when finished I will spray the ceiling white. Ugh.THE BOTTOM LINE: If you plan to DIY a vertical surface, this product can do quite well if you are just a bit handy. Buy all of your product at once, and verify that the cans are good (shake them). Finally, if I had to do a ceiling again, I would use the Part A, Part B cylinders with the hoses running to a gun. This way I would have omnidirectional ability to spray straight up if i wanted.

Works as promised and clean was made easier with the cleaning spray.
