Review: It’s a very good product for filling gaps. The foam settles down as some type of thermocol after drying. It can be used for split AC pipes holes in place of white cement. Also for gaps in windows and doors for keeping the insects out. But use the product carefully, as it expands after few minutes. You might end up wasting some of it while trying to fill the entire gap/hole with the foam. It’s better to put small quantity of foam in the gap/hole and let it expand. Then use it again if required. Be very very careful while using it. Use gloves. And Avoid it sticking to anywhere on the body, specially hairs on the head, facial hairs, hands and legs. It’s very difficult to remove after, might have to cut hairs too. And it's good if you use the entire Can in one go. Saving it for later is little difficult, as the nozzle and its discharge pipe gets clogged.
Review: Foam is denser than Lepage or great stuff. Fixed a creaking vinyl bath tub installation.

## 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.

### ⭐⭐⭐⭐⭐ Review
*by M***X on 4 December 2025*

This foam works great and it expands in a real significant way, so you don't need to use too much. It's all fairly self explanatory and it works down to 20 degrees, which I thought was shocking. I believe caulk only works down to 40, so it's handy it functions in sub freezing environments. A word of warning. It's exceptionally sticky and it can expand...unpredictably. If you're using it any place that may be overhead, use caution until it's done curing.
