There are different levels of polishing. When I looked into it I found it was 50% more than Epoxy for POLISHED. All epoxy fails eventually. The biggest problem I've found with my Epoxy floors is moisture underneath causing issues. No way around that f there ANY moisture in the area. Polished floors "breathe" and don't have moisture problems. The air may have a moisture problem but not the floors.

We were looking at having a building built. I would DEMAND a water barrier (just thick plastic) under a concrete floor. Tough lesson to learn.
