Professional Expanding Foam Spray Gun, 2 Insulation Guns + 18 Extenders

This is WAY better than I expected It is a metal gun and works as it should. I will never purchase the hand spray foam again the gun makes it go way cleaner for doing around windows and doors. The GS brand will reseal when removed so you can use it later.

Initial uses, works just as good as the $60 name brand gun, tips slipped off a few times but absolutely worth the price.

Anvil is the $30 gun sold at Home Depot. Great Stuff cans fit better, seal to the gun better and it just works better. Easier to clean and has a shut off valve to isloate the inside of the gun while changing cans. This prevents air entry and the moisture in the air "kicks off" the foam setting, which will clog your gun if you don't have this valve. While easy to take apart for cleaning, it turned out that about 5 econds spraying the gun cleaner through had the inside of this clean. Wipe down the outside with a rag that has been sprayed with the cleaner (wear latex or nitril gloves) I still recommend taking it apart to inspect that you sprayed enough cleaner. Put it back together, spray a little more cleaner and close the valve. The bad... the nozzles just press on and can blow off while spraying foam. 1 to 1.5 inch of duct tape and wrap the connection.

Absolutely awful device. I'm not new to expanding foam so I understand how it works. But this gun has lousy instructions for use or cleaning. I used it once and cleaned it thoroughly with the correct solvent can as I would any other hard setting chemical. The next use the gun was clogged. I spent 2 hours trying to get it to work again. There are no instructions or diagrams to disassemble and I think it is press fit together so it can't be taken apart To clean a clog. This was a one time use gun for me because I can't get it fixed. I am frustrated and I lost almost half a day time trying to do what should have been a 10 minute job. If you buy this understand how it works before you use it.

The guns seem to be of decent quality. I did notice that the cans don't seal perfectly to the orifice and so there is a little leakage, but cleanup was easy enough with some acetone before the foam cures. I appreciate that the barbed nozzle at the end of the gun is larger than some other brands and so this one fits the pattern spray nozzles included with the many professional PU foam cans. I would advise that if you are getting the Kraken brand of foam, this gun probably will not work because Kraken uses a smaller barbed nozzle. As a tip. If you are like me and need this gun to spray foam as a sealant in between wall studs or floor joists, I'd recommend picking up some 5mm inner diameter (7mm outer diameter) hose, a brass 1/4 to 3/16 hose barb, and a pack of assorted zip ties. With these, you can attach a pattern spray nozzle that usually comes with professional polyurethane foam cans to the hose barb and attach the other end to the gun using the zip ties to add additional security to the connection. Doing so well make your life a bunch easier when trying to fan spray the foam into various spaces like the ones I mentioned above. Also, it's a good idea to either wear clothes that you plan to destroy or put on a full cover tyvek suit. Be sure to cover everything including your head and use a face shield as the foam tends to blow back a little during application and while changing canisters. Naturally, gloves are a must and I recommend using PVC coated ones, but I'm sure others would work well too. When cleaning the gun, use the special cleaners that screw onto the gun just like the foam canisters do. This is simply pressurized acetone so having a quart or gallon of that around is handy so that you can use the "cleaner" for just the interior parts of the gun and the less expensive bulk acetone for cleaning the outside and yourself. Be sure to do this cleanup before the foam cures and keep your protective gear on. I learned the hard way that messing about with the stop valve (a nice feature of these guns, by the way) can cause the expulsion of some of the foam in the gun back at you. It's better to be covered than end up with egg, I mean sticky PU foam on your face. I hope some of this helps with your buying decision as I know specific information on these guns can be hard to find and no one likes buying these only to find out that they can't use nozzle attachments that need.

This makes spray a lot easier

Spray gun worked flawlessly at a much more reasonable price. Would definitely buy it again

Worked well as a replacement for Kraken foam guns

Picked up this 2-pack of spray foam guns for my new construction project, and I’m really impressed. I’ve been using them for window installs and general insulation work — sealing up gaps and cracks to keep the house tight — and these are easily the best guns I’ve used so far. They feel solid, are easy to handle, and the price was way better than anything I found at the local big box stores. Each gun includes a shutoff valve that’s smooth and easy to operate, plus a flow control knob for more precise application. The kit also came with several extra tips and extension tubes for getting into tighter spots, which was a nice bonus. For the price, it’s a no-brainer. Unlike the disposable foam cans with single-use straws, these guns make it easy to pause and come back to your work later without wasting material. Highly recommended for anyone doing serious insulation work.

Husband loves these… they have seen many jobs and continue to work great! Wickedly good bang for your buck!! We buy them as gifts now!

IT WORKED AS IT SHOULD

Cant beat the price, works really well. Time will tell how long it'll last

Haven't used it yet but looks and feels like a very good product, Sure beats using the regular cans when you only need to use a little bit. Then the regular cans are no good anymore when you go to use again.
