Spray Gun Cleaner - Expanding Polyurethane and Insulation Sealant Remover, Dissolves Spray PU 2 Pack, Can, 12.3 Oz.

This stuff works well, the spray gun is extra but works well. The company should include the cleaner solution with the gun because that seems like a scam not including it, if you don’t clean the gun after every job it’s garbage and now they get you to buy another one, pretty scammy. The insulation works very well and very tough, I wouldn’t be surprised if this has other uses in arts and crafts as well being that it is so tough and dense.

Works every time.

Great product

You don’t need a lot of this stuff to clear out the sprayer. It works quite well. The little spray time is very nice to to you can also use it as a spray cleaner for overspray etc. it has a strong gas like smell so ventilation is recommended. It also may dissolve styrofoam and soft plastics painted surfaces etc so use a little caution.

Do not buy if you’re looking for closed cell foam. Falsely advertised and no returns. This is open cell foam!!!

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

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.

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