Review: Good quality and works very well
Review: A few reviews on here saved me a lot of headaches while working with this sealant. I'd like to summarize how i managed to get great results and had zero mess/cleanup! *make sure the applicator snaps on correctly [it snaps on 2 sides - make sure they both SNAP before you begin] *press the trigger gently, as the product comes out at a very good pace even with small pressure *have the nozzle where you want the product to go as opposed to treating this like a long distance sprayer *if using in a larger gap than intended i found doing one row of foam and allowing to dry enabled me to then follow with a second row of foam in connection with the previously dried row [this allowed me to easily fill larger gaps than intended without creating a mess or having foam pull away from where i wanted the gap filled] *absolutely 1000% wear disposable gloves [better safe than sorry, as this stuff does appear to be extremely sticky] This is a fantastic product, but can easily be a headache if you don't take care when using it. I just refortified the insulation along the sides of my basement and i could not be happier! Zero draft and it only took 4 cans of this stuff [at the time of purchase, less than $30 - can't beat that considering the results]

## Questions & Answers

**Q: cubic footage yield?**
A: According to their Technical Data Sheet, 1 can will extrude a 3/8” bead approximately 134.0 ft under ideal conditions.  So the cubic volume is 0.375" x 0.375" x (134' x 12)" = 226.125 cubic inches. 1 cubic foot = 1728 cubic inches. Therefore it would take about 7.6 cans to produce a cubic foot.

**Q: Can i apply this on a hot surface like car exhaust? Doesn't it catch fire?**
A: I've used RTV silicone for minor muffler holes, good to 650 F.  But it is flexible and doesn't stick to anything so you need to get it globbed onto both sides so it holds.  Unfortunately the portion of a muffler that usually fails is where the pipe comes in (due to welding).  JB Weld might work better there.

**Q: Can this be used to fill gaps behind baseboard heaters?**
A: Not flame retardent

**Q: If this is injected between sheetrock walls, will it reduce sound transfer?**
A: If you want to insulate the walls between rooms, it would be better to remove the sheetrock and use a spray foam insulation product, rather than a spray foam sealant.  Bats of heavy rock wool might also be good sound insulation.  A spray foam product expands for a minute or two and you risk popping the nails/screws holding the sheetrock in place if there is not enough room for it to expand fully.  Trying to deaden the sound without removing the sheetrock would require punching lots of holes in the walls and spraying the foam through the holes, and then patching all of the holes and repainting.  This will deaden the sound between rooms, but it will require a lot of cans to do it.
