Used this for a 13'x17' shop, ceiling at 14'. 48 cans was just enough to get about an inch and a half on the walls, about a half inch on the ceiling. I probably could have done everything at an inch if I was more careful. It is strong and sticks really well, and a second layer after the first cured was no problem. This stuff is easy to use and a lot of fun. I did the shop in a couple hours, took breaks, checked for gaps that I missed. Some things I did to get the best result I could: -Stored the cans inside for two days before using them to ensure they were warmed up to at least 65deg. -Shook the heck out of them for 20-30sec. -Cleaned the shop really well, as dust free as I could (by no means perfect- there was a lot still on the walls). -Sprayed out the gun with cleaner every six cans, and wiped off the tip with a rag (sprayed with the cleaner). -Kept the spray gun adjusted to very little flow- this seemed to give me a lot more coverage and even spray. -Wear the protective suit, gloves, and goggles at least. I had a good fan that vented the gasses out so it wasn't that bad. -Have fun! I very much enjoyed this job and saved a TON of money doing it myself. It worked better than I expected (I read the same terrible reviews you probably did) and I think it's because I followed the directions and took my time and had fun with it. It isn't perfect, but I am very confident that it will work for my needs (hold some heat in the winter and some cool in the summer). I highly recommend this stuff for jobs this big and smaller. I already ordered more to do my wife's shed and fill some spots I missed in the shop.

It went a long way! If you follow the instructions, this is a great product and very easy to use. Change the tips out per can used and every 2 or 3, run a little cleaner through it and it flows well.

Foam works but after not using the new cans the spray foam from new cans did not work. After returning two boxes the seller WiosChem sent one back to me then ghosted me during my efforts to get my second box replacement. Thanks to Amazon I got credit for the second box they kept from me. I recommend foam purchased at Lowe’s or Homedepot in case you have issues with faulty foam too. Careful with WiosChem.

I bought a 10x16 shed cheap I plan on turning into a man cave bar. I bought this to insulate the ceiling and I should start this with I really had no clue what I was doing just read the instructions and started. It doesn’t expand as much as I thought and the reason for 4 stars is that you need to keep the can verticals so spraying needs to be very close to 90 degrees which makes the ceiling very difficult. Also, it isn’t consistent when trying to do angles needed for a ceiling. Definitely a learning curve and doesn’t always stick well…. Extremely messy (spend the money and buy a painters gown/suit… once it dries it doesn’t come off anything including yourself or clothes. For the walls it did amazing, keeping the cans verticals it was consistent and easy to layer. The next day it was hot and as you can see from the pictures there is a very noticeable difference in the area I sprayed vs what I did not. It took me about an hour to do it. - I plan on buying another 12 cans to finish my walls and hit any spots I missed - I was going to use the fiberglass roles but this seems to work better, faster, easier and much cheaper! Again keep in mind I had no clue what Iw as doing and just thought how bad could it be!

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.

Arrived on time and as expected. Product went on readily and clean up was great. This was used in a metal barn to hopefully provide some cooler temps in summer. The foam adhered to the metal and wood without any additional prep work (other than knock down webs). There does seem to be a temp difference when you walk in so seems to be helping.

After reading the reviews, I was a little worried and confused. But we put this on the top of our shipping container last night. It was actually quite easy to use. You have to be prepared and it can’t be messy, but the final product was awesome.

The foam product works great when applied. Although it doesn’t go far for the price, the product works as described 3 of 12 cans would not work to dispense product after cleaning and proper use. I understand that sometimes things don’t work but the company refused to provide replacement or refund for the faulty canisters (which are very expensive). Amazon doesn’t allow you to return the product because they are flammable leaving your with a inoperative product. The company wanted videos of the product “not spraying” which is like a video of snow not melting. Bottom line, the product works when dispensed but the company doesn’t stand by their product or refund. For the price I would expect better customer service.
