Foam it 602 Polyurethane Spray Foam Insulation Kit

TL;DR Kit was awesome, got about 550 sqft, it smelled for awhile but now it is great! Any questions, please leave a comment! EDIT: August 22nd, 2020 I ordered another 2 kits (602) directly from Foam It Green (used the $50 coupon code they send you but you have to pay for shipping... for some reason, it still ended up cheaper). This time, I had to spray foam about 500 sqft but at 2 inches so I needed 2 kits. I received a phone call from the shipping company confirming shipment and delivery times. Received my kits, opened them up to check for any damage and left them in my toasty garage until 2 days before spray. A day before spraying, I moved them to my slightly cooler basement and cleaned all my walls with a stiff brush and vacuum. On spray day, I hydrated and tested my mixture before spraying on my walls. I had to take 3 breaks due to the heat (it was 90+ outside and no AC in the basement). I constantly shook my tanks and after 4+ hours of spraying, I had some left over foam that I used in my crawl space. Once again, I got close to the promised 600 sqft and spraying was easy... my finger though is still numb from pulling that trigger (2 weeks later). Will buy again when I work on the last 1/3 of my basement! Ok, so I’ve read a lot of reviews on several different closed cell spray foam kits and all of them had their ups and downs. Lately, I’ve seen several negative reviews about this kit but I took the risk and got the 602. I liked how the color indicators tell you whether component A or B is working or not. For me, the kit was awesome and it worked so well and got close to the 600sqft as promised. So here is the full review as I explain my process of insulating my basement walls (roughly 180 sqft) and rim joists. I was also planning on spraying at least 2 inches of foam, if not more, so the entire kit would be used at 3 inches. • Order the kit at least 2-3 weeks ahead of time. If anything is broken, you can give customer service a call. My kit was fine and luckily I didn’t have to call. I did read the instructions and I was able to keep my tanks in the garage where it is a toasty 78-80F. • Prepare your areas. About a couple of days before actual spraying, clean your walls/rim joints/ceiling. Use a stiff brush and vacuum the area completely. The area I was spraying previously had fiberglass insulation (R7) and a ton of seeds/acorns from mice that got in from some unknown area of the basement. Cleaning for me took days! • A day before spraying, I took the tanks to the basement to let them equilibrate to room temperature. My basement was about 76F. I also put down drop cloths on the floor (DO THIS!) and I put nozzles in areas of the basement where I knew I would be stopping for more than 20 seconds (the kit says 30 seconds but the foam cured so fast, it was more like 20 seconds for me). I also put my tanks on a cart so that I could wheel them around to minimize lifting them (they are heavy) and kept them off the ground. • Spray day! Put all of your safety gear on. Get super cheap goggles (not safety glasses), a really good respirator, full Tyvek suit with hood, a cheap hat, Tyvek shoe covers and extra nitrile gloves (you can find good 8mil orange ones on Amazon). Depending on how much you need to spray, hydrate before and go to the bathroom! To use this 602 kit, it took me 2-2.5hrs straight without stopping. • Actual spraying: Shake canisters for 60sec! This is a must! I rocked back and forth, shook up and down and it was exhausting with all my PPE on. Before putting the nozzle on, always test into a waste container. If it turns green and hard within 20-30 seconds, slap that nozzle on and spray. I opted not to use the fan tip as I wanted more control and better coverage. Controlling the spray is rather difficult early on, not to mention that when the foam comes out, it sprays and dribbles a lot onto the floor. I think I lost a good 25 sqft in just foam dribble from the nozzle. I followed the videos and started with my rim joists as it was higher than the walls (the kit says if you need to spray ceilings or similar, start there first). Starting with rim joists also allowed me to make mistakes if they were to be made (as I wouldn’t see it). While the rim joists were curing, I sprayed around the studs of my walls and then filled in the middle. Slow and steady was best and there was no need to rush. If sprayed correctly, the foam rises after 10-20 seconds and emits some heat. Once I was done with all my walls, I sprayed an extra inch on my rim joists and went back to my walls for the 2nd layer, paying more attention to areas that had gaps and crevices like other users had commented on. Once the 2nd layer was finished, I didn’t wait the full 10 minutes to cure and added a 3rd spray, again, paying attention to areas that had gaps and crevices. Once I was done, follow instructions on how to empty tanks. • Some key notes: o Shake! Constantly shake your tanks. I shook them after every inch layer. Towards the end, I shook them in between, even for just 10 seconds. o It smells, even with a respirator! I had to stop any other work in my basement for a good 1.5hr. I did not have good ventilation down there and I put my air purifier (IQair MG) on high (which ran for a solid 2-3 days straight just in case). o Drop cloths! The kit doesn’t tell you but the foam just constantly dribbles out of the nozzle. o It will never be even but even 1-1.5inch uneven was better than my fiberglass insulation! o I lost feeling to my index finger (trigger finger) since pulling on the trigger took some substantial force over an extended period of time with no breaks. I sprayed on the 14th and I’m just getting feeling back now. This is why I gave it 4 stars for comfort because my finger is still uncomfortable! o Cutting the foam was pretty easy. I had a serrated insulation blade (for rockwool) and it easily cut the foam in areas where I over sprayed.

Be careful buying from this company. 1) The Kits never give you the actual coverage. 2) The design of the spray gun is flaky and can result in one tank emptying before the other and spraying uneven leaving an absolute mess out of the walls. 3) Their customer service is more like a "customer integration" when called. They will ask you million leading questions to prove that it was you and not their cheap defective kit. Their manual and operating guide is filled with disclaimers to cover themselves in case the kit doesn't do what it should do. I truly hated working with these folks and after spending $800 they treated me like a lair as soon as I contacted their customer service "Linda AKA the customer interrogator" who doubted me from the first minute. Amazon is investigating the methodology they use to get you on the phone and prove that you did something wrong if the foam is not producing the results anticipated. they ask to visit your site if you ask for money back or send the 100 pound plus tanks back to them for "testing" at your cost...incredible!!!! I ended up completing my project by buying another product called "two component Polyurethane" from another company, and actually got an expanding foam insulation covering the square footage it advertises. What a concept!! Foam it green may be called green since it brings in lots of money to this company. I never got my money back even partially..This is an inferior kit to others and would not buy again.

We saved 24% on our heating bill this last winter after using this to seal up our crawlspace in our 1880s house, with air leaks in the sill plates and brick and stone foundation walls. The product makes an excellent airtight seal and provides good insulation value. This kit covered approximately 400 square feet in a single thick layer. Very happy with the results. The instructions make it very clear that temperature of the product and temperature of the target area are critical. By sticking to these instructions, my installation went well. I even opened a heating duct temporarily to raise the temperature of our crawlspace walls to enable the installation. I spent a lot of time cleaning dust, spider webs, etc from the walls so the foam would adhere properly - much more time than it took to spray the foam. It is tricky while wearing goggles, to see if the mix is perfect - it can be the correct color but still gooey. This only happened for the first few seconds of use, and I probably should have sprayed more product into a cardboard box as a test until the mix established itself. I used almost all the included nozzles because I had to stop and move the tanks as I worked around the perimeter and internal walls of our crawlspace. You have to change nozzles after 30 seconds of not spraying. You're going to make a mess. Get a tyvek suit that has included booties (the included suit did not). Improper mixing also happened at the end of the capacity, obviously because one of the two components ran out, and the other didn't have anything to mix with. It is obvious when you are running out. So a small amount of material at the end took longer to cure, but eventually did. Disposing of the excess component was a pain, however, as it requires materials to neutralize the component you have left, and in my case took several large boxes to contain all the material. The instructions state that you should not put on too much material at once (too thick) or it can overheat during curing and cause a fire. It was not clear that this exothermic reaction would occur while neutralizing one of the components. I went slowly and had no problem even though I sprayed the extra into a cardboard box. Read about, think about, and prepare for disposal of extra material and the empty tanks before you undertake your project. Ventilation is vital. Use a recommended respirator. In an enclosed space such as a crawlspace, fumes can displace oxygen. Be careful. Follow the instructions carefully and this product will delight you. I'm very happy with the results.

Product works just like they say it does. I liked it enough that I ordered a 2nd one yesterday for another job. Only problem is the short (15') hose assembly. I was working in a tight area and could not lug the heavy tanks in with me. I ended up having to remove electrical plugs, boxes and all, and forcing the gun and hose through to reach the entire area. A 30' hose would have made all the difference. I read somewhere on the internet that you need to heat the tanks to around 85 degrees using electric heaters. There is no truth in that. If you have the tanks in a 70 degree or higher room they will work fine. Don't plan on using the product on very cold surfaces, must heat them first, since it won't stick properly (read the manual) and also don't plan to use this product on walls (read the manual again). FYI, shipping cost to Georgia was over $100 (ouch!).

We purchased this product to seal around and insulate on top of rigid foam insulation in the ceiling of the garage (which is also the floor of our bedrooms). I was anxious after reading all the reviews about tanks failing, however, we purchased 2 sets of these tanks and both performed as they should. We watched all the videos and read all the instructions. We prepped thoroughly, and followed all instructions, and it worked as expected. (like painting, I think success is in a lot of prep work). The bedroom floors feel much more comfortable and the garage is much quieter! My only concern is that I had assumed our city hazmat disposal would take the tanks when we were done and they didn't, so it would be great if this company offered a recycling program for the tanks. Learned tips: They're not kidding--really let the product run into a lined trash can until you get the right mix. We got just blue for a while at the start of each tank, which looked "green" to us the first time, and it never solidified. We had to scrape it off and respray, and it is not easy to clean that stuff off of anything! Icky. Also, as the pressure started decreasing the spray started sputtering (probably because we were spraying overhead); we thought we were near the end of the tank, but it kept on going for quite a while in that state, so let it run as long as you are still getting the right mix/color. And cover everything! The "snow" gets on everything when spraying overhead, but scraped up easily off the concrete floor using a hoe. Finally, the tanks are heavy and we had a large area to cover, so we strapped the tanks to the scaffolding we were using and wheeled them from location to location, and glad we did. Good luck!

First, this is the first time I have had cause to ever write a product review. I bought two of these kits and installed the first one on the roof of my garage with no issues (although it did not cover 600 square feet at 1" thick). The second kit had a problem, mixing the two chemicals evenly, which we ultimately found to be an issue with the gun. This was discovered after spending 4+ days of troubleshooting on the phone with the company. Not once during this time did they apologize or show any empathy for the problem with their product. In addition to wasting several days of my time, we wasted about 1/3 of the product troubleshooting. Finally, after not giving in to their bad customer service and unapologetic demeanor, they sent a new gun (with a hose that was too short, causing other issues) and I was able to get about 400 sq ft out of the tank. This also meant I could not finish my 750 sq ft ceiling with two kits. Finally, after sending the new gun which solved the problem, they claimed this was a courtesy instead of being apologetic and admitting their product did indeed have an issue all along. Next time I will purchase the product from one of their competitors.

I bought 3 of these kits for an off grid (and off road) cabin. Hiring a professional wasn't an option. I wish I had been... I insulated a 600 sq-ft floor with anywhere from 1 to 4 foot of crawl space. My biggest issue is that the foam didn't come out as a nice smooth uniform surface. Instead, the surface ended up being almost pebble like. I uploaded a picture of it. For scale, the beams in the picture are 24 inches apart. I'm not sure what to call this kind of texture, but I'll say that it has a lot of "exclusions". That is, places where the foam has puffed up, but lots of crevices where the foam didn't fill in very well. I could live with the looks, but the problem is that these "exclusions" really kill the insulation value. The cold enters all the way down to the bottom of these "exclusions" and so the effective foam thickness is basically just to the bottom of these "exclusions". Maybe this is normal, but I'm not happy with the result. As far as I know, I did everything "right". I did this in the beginning of August. The average temperature was between 75 and 80F. The tanks were almost a perfect "75F". I shook each can up for one minute. I read the instructions the day before, and then again the day I sprayed. The instructions mention that some of the foam will fall like "snow". Well it did, and it got on EVERYTHING. Worse part of it was it getting on my goggles. By the end of the 2nd set of tanks, I could barely see what I was doing. Thank goodness I had an extra set of googles. This stuff gives off a lot of chemical vapors, so make sure you have a respirator rated for that. I don't know why I didn't better coverage. Maybe it's because the pressure from the tanks isn't consistent like what you should get from professional pumps? I ordered 3 "complete kits", which meant the hoses and all of the extra nozzles. I'm glad I did this. I found where they sell just the foam tanks for $100 less and I think you're expected to reuse the same set of hoses/sprayer. However, none of the 3 sprayers would completely seal off the chemical flow when I released the trigger. A little bit would continue to slowly leak out. So I would spray an entire set of tanks before taking a break. Their instructions made a VERY big deal about "don't let the sprayer get clogged with cured foam, you'll ruin it!!!". If I were more experienced with the kits, I probably would be more relaxed about working with the foam and could have reused the holes/sprayer, but I ended up just using a new set of hoses/sprayer for each set of tanks. You get two tanks, one is yellow and the other blue. The chemicals are yellow and blue in color and are supposed to mix to a light green. If you only get yellow or blue out, one chemical has run out. Well, for some reason the blue chemical was in the yellow tank, and the yellow chemical was in the blue tank. My blue tank was getting light, so I was expecting it to run out and I'd just get yellow coming out of the gun. The visibility wasn't too well, so I didn't notice that the spray turned blue because the blue tank ran out! WTF??? I was looking for the flow to get lighter, not darker... So I went to the web site to see what you're supposed to do when you just covered a big area with one chemical, but I didn't find anything. That sucked. I did my best to wipe it down and sprayed the next set of foam over it. And I made sure I didn't run out on the last set of tanks. Another small complaint is that the shipment was almost 2 weeks late. After ordering, Amazon said I'd receive the tanks in 1 week. It took 3 weeks. Thankfully I didn't need them for 4 weeks, so it worked out. But from my experience, don't expect on time delivery. I spent over $2400 on these kits and I'm not thrilled with how it turned out. My floor is now insulated. Some spots probably only have an inch, some probably have 5 inches, and there are a lot of "inclusions" in the foam.... I wish I would have just bought foam board for half the price and went through all of the installation labor. But maybe I'll absolutely love how well this stuff insulated the floor and I'll be a "warm happy camper" this winter. If I change my mind about how I feel with the foam, I'll try to get back and update this review. I guess my conclusion is that this was too big of a job to do with these kits, made extra difficult because I had to spray everything up at the bottom of a floor. I don't know that the company could have done much different. The product worked more or less as advertised.

I used this for the rim-joist in our home. A couple things: I put 1in solid core foam (cut to size) in each bay before using the spray foam. I also was able to do a relatively 'thick' spray to close off any potential gaps that may have existed. I turned off the HVAC and turned on some fans in the windows to exhaust out the fumes, and wore a mask (3m respirator). I did a LOT of prep before using this product. Cleaned, vacuumed, installed additional insulation etc etc etc. This spray foam was easy to work with, and did it's job as it was supposed to. If you are curious, this kit was purchased because - every "foam insulation company" I contacted either did not call back (due to no interest) OR this was too small of a job. That is why I went DIY on this one, that and: I was advised by one of these companies that they have a minimum $2k job because ... (insert your answer here, but I will choose that everyone needs to eat). IF you're on the fence on doing this job, and purchasing this kit: I would do it again, and use this kit. Also: their tech-support is solid.
