Keep in mind that 20 Board Feet per can at 1" thickness is 10 Board Feet at 2" thick and 5 Board Feet at 4" thick. If foaming between 16" centered studs, 3.5" thick, each can of foam will cover about 4.73 linear feet (An 8' x 8' wall 3.5" deep will require about 10 cans). Allow each layer to expand fully before applying the next layer. Cleaner instructions say to leave cleaner attached to gun, but the can will reseal if you remove it from the gun (you will get some acetone on your gloves while unscrewing the can). *Remember, the cleaner is acetone and is flamable!
Outstanding product. Highly recommended. Easy to use.
Works great. Easy application. Comes with everything you need. Great product.
We used the closed cell foam insulation in our basement. We actually did 2 houses with the 600 board foot product. We were worried about clogging the tips so we bought extra. We thought the fan tips would work better so we bought more of those. We found that the process worked great, we did not need to worry about the tips clogging as much as we thought, even when we transported the product between houses and started it back up again. We also did not even use any of the fan tips as the cone tip worked perfect for our application. The only negative we found is that the tip does drip a little bit so we used cardboard on the floor but we still had spots where the foam got on stuff, but that was easy clean up and not a big deal.
Very good product. Easy to apply.
Covers board feet as advertised.
Only issue was when using the spray cans they should be warm or else they do not spray properly. Here in Northern Ontario cans sprayed best at plus 25C temp. Even the purple colour is unique.
