## Questions & Answers

**Q: Can this be used to fill expansion joints in an external concrete pathway?**
A: Hi, I am not 100% sure. The product I purchased was for a water prevention gap filler. My understanding of movement/ expansion joint fillers for concrete May be better to use grey coloured polysulphide (two part mix or maybe one part)  as more flexible and aesthetically pleasing . Most hardware/ DIY stores should be able to advise on this. Good luck. Mike P

**Q: What is the shaky stuff in the bottom?**
A: It is a drying agent to prevent moisture build upin the end of the tube.  The sealant cures with moisture. This stops the plunger in the tube becoming stuck before you use it

**Q: w[ll it bond glass to wood**
A: All good thanks 👍

**Q: is this product in date**
A: well , im not aware of the tubes being out of date, the tubes i used were over 12 months left use by dated and i very much doubt the vendor would sell you old stock.
