Review: Product came in tact, nothing missing. Love having the tool now so I only need to purchase the cans as needed. No problems with the nozzle. Odor was not as overwhelming as I was prepared for , but there is enough within the first 5 or so minutes of application that a re-breather is necessary and window open to air out. A simple dust mask will not do. The picture is not intentionally at a distance, but it gives an overall picture. This room is 10x11ish, 9foot ceilings probably made a big difference compared to had they been 8ft (in other words, I used more product per board pass). I had similar experience as another reviewer that showed the product seemingly separating in a matrix of globs and runs. For me, this only really occurred on the one remoded wall previously added by the former owner (they had framed to close an old passageway with OSB). The inner walls of the rest were the cedar type (1939 built home). The foam adhered just fine there. Here’s some considerations. First one also related to another viewer is the suppose ‘dud’ or two that oozes and doesn’t spray. Each of the two boxes of 6 cans coincidentally had 1 can that felt noticeably heavier/denser contents than the other 5 in each box. I recognized this especially when giving them the shakedown - and I shook them down vigorously. The denser feeling canister did not seem to “pressurize” any of notice. The other 5 cans that felt almost lighter and fully pressurized - all sprayed just fine. The oddball can was the oozer. Call it coincidence, but I had the suspicion then that each box had one can intentionally for large gap filling (maybe filled with less accelerant or activator). Why else would they include the straw and plastic fine-tip to put on the nozzle applicator for applications you would not want to blast foam out of (it would be a disastrous mess!). Given this theory, I shelved the other “dud” for later use. Second consideration that I failed to slow down and think on before I went through 10 cans, was the applicator nozzle trigger regulator (the screw knob on the back of the gun). I toggled that in a similar fashion as a texture hopper. But I later learned it doesn’t work the same way. The knob is meant to reduce or increase the amount of depression of the trigger itself, not open or close the channel (like on a hopper). I opened this trigger knob further than I think I should have, which I hypothesize is why the foam came out of the nozzle with a vengeance, and caused more separation of the mix or simply created too much air in the passage of the nozzle tip, hence why you may end up with real thin and easy to blow through passes, and requiring several more passes to get the coverage you want. Theoretically, next time (and I suggest), sparing one can for the experiment, to test the levels of that trigger control knob plus using different speeds of each pass and distance from the surface. I think I would have had more expansion had I slowed down just a little, and closed that trigger to half what I had it. Also you don’t want to pass back over a thicker fresh area accidentally too close - as it will blow right through what you just applied. Given how I did my first run with this type of product, I still got the result about 90% what I wanted, which was about 1-2inches depth of coverage. By no means was I expecting professional grade expansion, or to be able to more than just one room. This item is perfect to give you a 1-2 inch “seal” of insulation. I also think that dialing this trigger back some will reduce the good amount of foam “dust” that it produces. Based on all that, I have no impulse to try another brand. Once I can afford it, will try another batch of 6-12 cans and test my hypothesis.
Review: You can never have enough gun cleaner when you're foaming, right? This stuff is priced right and works perfectly. Going through about 2 cans a week and haven't had any issues. Totally happy with this product
