Kraken Bond Fastcoat Fire Rated Spray Foam Insulation Kit Closed Cell in a Can 40 sq ft (2x27.1 oz.) (R-Value 11.32 / 2in) - Spray Foam for Garage Door, Attic, Wall Gun & Cleaner Not Included, 2 Pack

I bought the 12 pack. Wanted to get a basic coating on the ceiling of my cabin's Gambrel (like a barn) roof. Cabin is 10' by 24' and the roof is about 374 square feet. I was only going for one coating, and it almost did it. I probably need two more cans to finish the coverage. Gambrel roofs are slanted, so the ceiling nozzle worked for me. Couldn't have done it with the nozzle made for walls. I was careful to not let the cans freeze while I had them, I kept them warm, and shook them all ahead of time, so that I could go from one can to the next quickly without needing to clean the nozzle until I'd used all the cans. It worked, but I had to prep everything carefully in advance so I could keep moving. Don't skimp on the preparation. Especially if you're doing a ceiling, it will be messy. Whatever's not covered will get stuff on it. I was dumb enough to not wear something over my hair, and had to use the solvent cleaner in my hair to get the stuff out. Also, even though the spray doesn't have a terrible smell, I was also foolish to not use the included mask over my mouth and nose. The stuff doesn't taste good or smell great when it's inhaled, and you will inhale it, especially for roof work. Glad I used old shoes, the cover suit and the gloves that were included. The stuff sprayed on well with no problems. It wasn't super easy to do it right, but easy enough for your basic weekend warrior. I sprayed the entire ceiling down with water in a spray bottle in advanced, as recommeded. Only one small section of the ceiling peeled away after spraying, like a 2' by 9" section. Everything worked as noted in the Youtube videos I watched. It will make a difference in keeping my little cabin warmer in the winter and cooler in the summer, and was worth the money, even for just one coating. I'm hoping it will also seal out some of the bugs that make their way in every summer. Pretty happy with the overall effect. Not cheap, but much cheaper than other options. Would buy again, and will probably buy two more cans to finish up a couple areas. The spray gun and the cleaner that comes with it is good quality. Be sure to clean up the gun afterwards, it could last for a long time.

I was pleasantly surprised at how well this kit worked out. I am a semi-retired builder working on a small addition/remodel. Like anything else you try for the first time, it takes a little practice to get where you're applying it pretty evenly. I wanted 2" in the wall cavities, so by the time I was done with the 2nd coat, it didn't look too bad. I had about 300 bd. ft. to cover @ 2", so yeah, they might be a little optimistic on their coverage claims, but this stuff hardly goes on nice and flat, so make sure you allow for a little extra when figuring what you need. With the 18 can kit, you get 2 cans of foam cleaner, and I hardly even used any of the first can. The gun sprays clean in seconds, and spraying a little cleaner on a paper towel worked quickly to wipe off any foam on the outside surface of the gun. There was not a lot of odor or fumes with the product, which was nice, as this was on a remodel in an enclosed space.. Any overspray on the studs, etc. was easily peeled off with a 3" scraper at the end of the day. The fact that this foam is fire rated is an extra bonus. I would highly recommend this product.

As far as a DIY foam insulation system, it is excellent. Very easy to use at fair price point. Takes a second to get tweaked to your own personal operating style but after that, it makes quick instant gratification. Only negative which is just happens sometimes is 5 of the cans out of the kit we're defective and would not spray. They did seem as if they had already started expiring. I have already contacted the seller and will update my review soon. But don't let that stop you.

this product is great. I've used it many times before for small projects and fixes around the house. works great!

I’ll be honest—I’ve had bad products before, but at least other sellers tried to make things right. This company does not. I purchased two cases of their Kraken spray foam along with the spray gun and stored everything indoors until I was ready to use it. When I finally went to spray foam my bathroom, all but two cans were completely unusable. I could literally crush the cans with my hands because all the pressure had leaked out—yet no foam had escaped. That tells me they were defective straight from the factory. Because it had been over 90 days, I couldn’t get a standard exchange. I reached out to customer support, and while they initially seemed willing to help, they eventually stopped responding altogether. After more than a month of waiting, I’m left with no resolution. I wasn’t asking for a refund—I simply wanted the defective cans replaced. The complete lack of follow-through is what’s most disappointing.

The PPE they provide is pretty decent and the spray foam works when you're able to dial it in and get pressure right. However, 3 of the 12 cans I received were bad. They all came from the same box and extruded a dark gooey substance instead of spraying. It looks like they cured in the bottle and I am having a hard time getting a replacement for these cans.

I used this product to insulate the walls of a walkout crawl space under my cabin. The walls were metal with no current insulation. I had a quote of $8,000. I purchased two boxes of Kraken insulation and had more than enough. I even put it on twice to double the R value. I ended up selling the second box. Follow the directions and you will have no problems. I only had the tip get plugged a couple times. Once I changed the tip, once I took the insulation can off and ran the cleaner through the tip, easy fix. BTW, I bought extra tip and did not come close to needing them. They give you protective goggles, gloves and a suit. The suit is fine, but get better gloves. Also I got a full face mask with air filters. Never fogged up once. Tip: if you get the insulation on something, DO NOT TRY TO WIPE IT WITH A RAG. It will smear and never come off. Let it harden then chip it off. You can use acetone, which is what their cleaner is, to remove it as well.

A little messy but worked well to seal all the floor joist leaks in the basement. I use the foam board first and then used this product over the top and to seal all the edges.
