So, if you need to do any overhead big gap filling, forget it with this. It may work on walls, obviously on the floor, but a big nope overhead. I had to keep the stream going for about thirty seconds before it would engage the larger flow, every time that I stopped I had to do this again. It would just spit a normal thin stream and fall all over the place. I tried starting at the wall, piling it inward, failed miserably at shooting the middle, nothing really worked until the wider flow would kick in. The wider flow was still disappointing overhead since it drooped pretty fast. If I wanted to seal an area before placing foam what would I need foam for>

Expands a lot, but only if you shake it up as instructions say.

Using it to help keep rodents out of hone, finding the small openings they squeeze through.Foam does expand well.We're told by exterminator that foam also poisonous to rodents. Yes!

Fairly easy to work with, give you enough time to clean up if you overshoot. Make sure you shake the canister well, as directed. Also, keep it upright, take breaks and re-shake. Do not remove the dispenser once installed - just leave as is. The overflow will harden on the tip, pull it out and can continue to apply. I willed several deep 1-1.5" wide holes with no problem. The dispenser trigger allows for a good amount of control to apply small amounts in more delicate areas.There were a few times, maybe due to the angle I was holding the can, or the prolonged use, when it would stop releasing foam. Taking a break, shaking the canister and holding it upright usually helped.

I have always been a fan of Great Stuff foam for filling cracks to keep out insects, rodents and drafts, but that darned straw would make the disposable cans clog if you didn’t use it all up in one shot. This new magic straw really works. I’ve used it 24 hours later, and it’s still fine. It makes things much easier on me, and I’m wasting less foam now.

I received my insulation foam today, easy to assemble just screw the nozzle on shake an spray where you need it. I have some holes around radiator and in bathroom around pipes that I needed to seal up, very easy to use read directions first. This is an update I had over half a can left and I went to fill some more holes and it clogged up on me, I would suggest using the whole can if possible because it might clog up, not saying they all will just stating mine did.

I used it to patch a door hole, and it worked well.I first jammed a large piece of cardboard into thehole. Then I sprayed Great Stuff into the hole andaround the cardboard as well as I could. Then I letit set up. It saved me the cost of a new door.I will now use bondo to fill in and level the rest ofthe hole. Great Stuff did its part perfectly.Note: the sprayer will leak foam at the can openingas well as the tip of the injector. It gets the job done,and that's what counts, pretty or not.
