## Questions & Answers

**Q: This will seem like a bizarre question, but does it smell? (Like the majority of Chinese-made closed cell foam materials.)**
A: I use it for taxidermy purposes and havent noticed any smell.

**Q: Is product gray or black?**
A: Mine was Gray...

**Q: Can i use that to repair my garage floor cracks with the concrete caulk?**
A: I wouldn’t. It’s just foam. If the crack is huge I would use sand as a filler and apply a deep layer of concrete patch

**Q: does this break down or come apart easily when wet?**
A: No. Its foam.. it doesnt break down at all
