Customer Questions & Answers

How do you clean the Pro 14 gun

Using foam is a messy process and once dried is a mess in itself. How do you keep the gun from getting plugged up and if it does do you have to throw it away? Thanks
Asked by: Anonymous
Pretty much is the case once the foam cures your gun is toast. Another $50 and you are back in business ; or file a suit against the chemist that never got around to developing a solvent that would dissolve the foam and eliminate the costly replacement of clogged guns. Try somewhere in the Caribbean as rich chemical engineers frequently travel to sample the female talent that is bonita.

Can you remove a can and reattach later on?

I have read reviews that state you have to use up the can you have attached to the gun. If you remove and try to use again later it will not work. I am looking to get this for some of my team to use but I do not want to buy a gun for each can they may have to use completely.
Asked by: 4line
Not really. It is designed so you can leave the can attached and ready for use up to thirty days from last use to help prevent wasting foam like the disposable ones. For long term storage without use for longer than 30 days, you need to removed the foaming can and clean the gun with the cleaning can/solution, which is really only pressurized acetone.

Where do i find more tips for the Pro 14 foam gun

Asked by: Anonymous
Not sure what tips you're looking for as it's pretty self explanatory. Unfortunately, currently there isn't much out there as far as techniques for use. As far as laying a nice bead of foam, keep nozzle at an angle if possible and draw the gun with consistent speed to match the amount your dispensing.

I have no trouble with the gun , it's the fact that my oldest kid used it without permission and the insulating foam has cured in the gun. I said no problem we will soak it in a solution of Great Stuff solvent that will dissolve the "cured" foam and have gun working good as new. NOT! You mean if you let it cure in the gun ; you toss a $50 in the trash and mosey on over and drop another $50 on a new one. It is evident that the manufacturer didn't do enough R&D in order to provide a solvent that would break down the "cured foam " to a liquid that would allow the gun to spray clear any gun clogs.

I attached can and stored it standing up with gun handle on table. The tip of gun gets covered in foam. At first I thought gun was seized because no foam would come out. I waited till foam hardened and just used sharp knife to cut off foam around tip of gun, especially the small tip on end of gun. After doing this the gun always works. I have kept the can on for several weeks and used it several times and never have a problem. The knob on the gun allows for regulating the flow. The main thing I found is to not stand the gun by standing the can on the table but by standing the gun on the table and can in air. It seems to keep the foam from hardening in the gun itself.

Rated 1 out of 5 by from Can't last a month. I like the Foam from the gun it is much better controlled than out of the can and it goes a lot further. My problem boils down to this there has never been one of these that we haven't had to clean after each use. I own a contracting company and we use these a lot. Unfortunately I spend more on the cleaner than the glue because they have to be cleaned after every use or the foam will set up inside of them. I've tried leaving the can attached before and the next day the gun was seized. I don't mind the gun and when cleaned after use it functions well; I mind the company and putting forth this obsured idea that they can last 30 days. Moreover I waste foam as about 1/3 cans removed with foam in them seize up and prevent reuse even when cleaned. This is a decent item for production but everything else sucks.

Rated 5 out of 5 by from Will never install spray foam without it I was insulating a cathedral ceiling with rigid foam and needed to foam the gaps. The cost difference between this gun and its "pro" can and the regular cans seemed like a no-brainer - 2 hours, 3 regular cans, and a mess of epic proportions later i bought the gun and wish i had from the get go. It cuts off as soon as you let go of the trigger which allows you to put the foam exactly where you want it. It holds the can upside down even when foaming overhead which keeps the foam flowing. Lastly, it controlled the mess. If you have a lot of foam to install its worth the investment.

Rated 1 out of 5 by from Save your money! Worked great for the short time that it worked. I used the gun cleaner religiously but still it seized. The gun is clean as a whistle but the threaded piece that holds the can to the gun stopped working - foam can't get through no matter what I do. Tried calling Dow (almost impossible to get a person by the way, I had to pretend that I had a health issue with Dow products), but they don't offer replacement parts. The warranty is only 30 days too which tells you how much they believe in this product. I guess they expect you to buy a new gun every 30 days.
