How to remove hardened spray foam
I found way to remove this from vinyl siding after it's cured and hard. Use Citristrip orange paint remover. Put it on thick and let it set 15 minutes. Then take a wire brush and Brilli pad to it. Takes some scrubbing, but.it does come off.

      Nozzle impossible to control; buy the Pro gun instead
      I'm not a contractor so I bought Great Stuff in this DIY container to seal up cracks in my garage walls before insulating. As others have said, the nozzle is extremely difficult to use; the foam either barely comes out or it splatters all over the place. I was glad I was wearing a tyvek suit. Plus, as I know from past use, if you stop partway through a project and don't use the whole can right away, the nozzle seals up and the can is useless from then on. So I bit the bullet and went back to Home Depot and got the contractor-grade Pro Gun, and containers of sealant and cleaner. What a world of difference!!! The flow from the gun is finely adjustable and easy to set up for exactly the amount you want. Plus, you can leave the gun on the can and use it again and again, for up to a month. Unless you're on a very tight budget or are much better at dealing with frustration than I am, skip a few lattes and put the money toward buying the Pro gun; the job will be much easier and much more enjoyable.

        Works well
        The foam sealant works great and closing up the gaps from running copper pipes through the wall in my garage. I used this same brand but specifically for windows and door jambs recently and it is fairly easy to use. Can be a dirty job if you use too much foam. The foam continues to come out for about 2 seconds after you release the trigger. So it's best to release early before you want to end.

          It won't stop, it keeps getting out!
          I sealed a couple of cracks and holes in my basement and everything worked great until I decided to stop and keep it for the next project. It just never stopped, it's in my garage now and it keeps coming out, I see a big blob of gooey stuff already and I am a bit worried that It will fill up my whole garage and I won't be able to open the door in the morning.

          Hi, Tim - Thank you for sharing your concerns with us regarding Great Stuff™ Gaps & Cracks Insulating Foam Sealant. We apologize for any inconvenience you may have encountered with this product. Once the foam has cured, it cannot be removed with solvents and the only option is mechanical removal. On hard, smooth, or polished surfaces this may be accomplished very carefully with a single-edged razor blade. If you can see the bottom of the can and it is still within shelf life, you can return it to the point of purchase for a refund or exchange. Great Stuff™ Insulating Foam Sealant products are not designed for reuse as one-component foam cans will seal themselves shut if left for two hours or more after the initial spray. We have developed a new dispenser called the Great Stuff™ Smart Dispenser™ that does allow for reuse up to 30 days after the can is first used.

            You are using spray foam wrong
            Take the straw off and you have a full blast substitute for a spray foam kit. 40 cans completely air sealed my attic and cost half of what the smallest froth pack costs.

              Nightmare to use - coaider Loctite
              For context Im a diy’er with no prior experience with spray foam. We moved into an older house which had gaps and holes internal to the house that were letting in pests and mice. So I turned to spray foam as the solution for larger gaps where caulking wouldn’t work. I started by buying 3 cans of this stuff. Let me tell you, it’s a nightmare to work with. Why? 1. The product comes out so quickly it’s difficult to control. You end up spraying way too much then have to spend a lot of time cutting extra. 2. Because of #1 is gets all over the place. Your hands, floors, clothes...really anything around. 3. The screw on spray tube is defective. With all three cans, the product began leaking out of the underneath of that screw on spray tube. 4. Some cans barely worked at all. One I got one spray out of before it jammed up and I threw it away. Overall this product is terrible. I gave up on GreatStuff and went and got a few cans of Loctite Tite Foam. Solved every problem above. Easier to control the spray, easier to clean up, and no leaks out of any of the cans. From my experience, vastly superior product. Having said that, in fairness, i have no results yet on which is more durable. A few tips if you’re like me and want to use this stuff: * use caulking wherever possible before turning to this * It expands, a lot. You can always add more so use lightly. * Spray foam is flammable. VERY. If I had known this up front I would have gone a different route all together. * Make sure you have plenty of disposable gloves. * Keep lots of paper towel around and a few wet rags to clean up. You’ll definitely want to wipe up overspray. * Get some acetone if you’re going to want the finished product to look nice. I didn’t care about that for where I put it so I didn’t bother. Good luck.

              Hi, OCDad - Thanks for sharing your concerns with us regarding Great Stuff™ Gaps & Cracks Insulating Foam Sealant products. We are sorry for any inconvenience you may have experienced. As recommended on the label, please use protection to avoid contact with skin and eyes, so please wear gloves and goggles. Uncured foam can be removed with acetone, but cured foam requires mechanical removal from surfaces. It is not harmful if you get it on your skin, but it will take time and effort to remove it. Also stated on the label, cured foam is combustible and may present a fire hazard if exposed to flame or temperatures above 240F (116°C). We have developed a new dispenser called the Great Stuff™ Smart Dispenser™ that allows for greater control and ease of use. As our retailers sell their existing inventory, they are restocking with the Smart Dispenser™ products which will be available wherever Great Stuff™ products are sold.

                I used this to fill in the gaps around a wall-mount AC unit, so that I could tile around it, instead of using regular moulding. Worked out great.
