Akfix Thermcoat Fire Rated Spray Foam Insulation Kit 240 sq ft (12x27.1 oz.) - (R-Value 11.32/2 in) Closed Cell Expanding Wide Sealant Thermal Insulation for Walls and Attic - Gun & Cleaner Included

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.

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.

I purchased a 12-can kit of Akfix Thermcoat on March 30, 2025. Due to project delays, I did not start using the product until January 10, 2026 (about 9 months later). Unfortunately, out of the 12 cans, only 3 were usable. The remaining cans were completely solid inside and unusable. The product did not list an expiration date—only a manufacturing date—so there was no indication that storage time would be an issue. I did not inspect the cans when they arrived, which in hindsight was a mistake. When I contacted the company to request a replacement or refund, I was told that because I was outside their 90-day return/refund window, nothing could be done. This was very disappointing given the high failure rate of the product and the lack of clear expiration information. I would strongly recommend inspecting and testing all cans immediately upon delivery, as you may have no recourse later if defects are discovered.

The application worked great. The insulation stuck to a metal roof in a quonset building. I got lucky in that I ordered the 12 bottle package, and only needed 11. The last bottle I used to touch up bare spots.

HEAVY box! Foamworked very well. Insulating our unused fireplace that’s getting new electric fake firebox. I guessed I’d need 4-6 cans.i used 5. I bought 12 in the kit. May have future uses for this. I recommend: - Spray water on the surface first. The foam almost explodes much more efficiently. - Wear the gloves. - Use a good aerosol protecting respirator. Because chemicals…. - DO NOT wear your prescription glasses. I did… - Maybe wear a disposable bunny suit. I learned the foam “sprinkles” do not come off cotton t-shirts in the wash. - Consider 1 can of cleaner for every 6 cans of foam. This kit came with one can. No problem for me as I only used 5 cans and already had a gallon of acetone, needed for much non-gun cleanup. So get a little can of acetone if you are buying 12 can kit. Should be plenty. - Spread a drop cloth or suffer the wife’s righteous ire. See pics: fireplace, flue.

Works well as long as your fast and don't get interrupted. Wear a mask but something better than the one they supply you with. Same with the gloves. Cleaner for guns works great. Price is too high but product is good.
