## Questions & Answers

**Q: Are the fibers AR fiberglass (alkali resistant) ?**
A: I made hypertufa pots with the fibers in the mixture since they are glass fibersI believe they are alkali resistant

**Q: Will this work with self leveling cement?**
A: First if your using self leveling cement you most likely are and should be covering it with tile or some type flooring. It should not really need the fiberglass fibers for strength since it is getting covered up. It is possible it will work but don't use a heavy amount. I would try a small test spot on a piece of plywood or somewhere. See what other answers you get back also, or ask the seller too

Absolutely what it says. I ordered what I got. I made a mistake thinking it was 5lb but it was actually 4lb. I am so sorry. The cut is good and the weight is correct. I will be ordering more in the future.
