## Questions & Answers

**Q: Do you use this before using the cleaner/degreaser AND the concrete etch?**
A: I ground off the old surface it was fresh so I did not clean it but I would think cleaner/etcher, moisture stop an then floor coating

**Q: Will this work with a self leveling concrete (e.g mapei)?**
A: yes

**Q: I need to both level the concrete and create a vapor barrier before putting down epoxy in garage. Should I level first or use this first?**
A: Vapor barrier first then use a primer before the leveler. Need to seal the concrete so the moisture doesn't cause the leveler to unbind from it. It's also a good idea to use the correct primer afterwards to allow the leveler to achieve a good lasting bond to the vapor barrier.

**Q: Can this be used on vertical surfaces?**
A: Not sure it would work, however extremely disappointed in the product. After a summer of doing everything right, into the fall weather it started to peel.
