I bought an older house and just had epoxy floors poured poured by a highly rated pro in my area. The end result has far more quality issues than I would have expected - and that's why I'm here, I don't know if my expectations are reasonable.
This is epoxy over a wood subfloor. The goal was to use epoxy to even out any local low spots in the wood subfloor, and tie everything together with something a bit less brittle than self-leveling concrete.
It's had a few days to cure and I just walked through the house this morning. Here are the quality issues I noticed.
1) There are ridges from the pour. You can tell where a bucket of material was dumped and it failed to feather itself out. There are ridges like this all over the house.

2) There appear to be footprints embedded in the epoxy. It looks like someone was walking around in cleats in half cured epoxy. These are not as prevalent as the ridges but they're still scattered through out the house.

3) There are a few irregular lumps of material. They are small hills and they dont match the level or color of the rest of the epoxy. Maybe some partially cured material got mixed into the epoxy?

4) You can visually see where there is a seam in the underlying plywood. At some seams, maybe they weren't sealed properly and the material concentrated there? There are pinholes in these seams too so I'm pretty sure thats from material leaking. The surface is flush, it's just visually obvious for some reason.

To me these are obvious quality issues, but I dont know what the industry norms are for quality expectations on wood sub floors. Which, if any, of these issues are legitimate things to complain about to the contractor?
Bonus question if you know: I suspect the only way to fix this is to grind the high points level and do a skim coat and top coat - is that correct?
For my next steps after the pour, my preference would be to just have the epoxy floor. I don't intend to put down another layer of material at this point. Maybe sometime in the future, but for now I'd like to move my stuff in and start living in the house. But if the contractor did a below standard job (based on industry conventions, if any) then I'd prefer to have those addressed before I move my stuff in and have to take it all back out for the fix.
