imo bare concrete is the best

we've looked into the roll out epoxies etc. but the thing is, when that stuff starts to peel up or flake it looks like complete garbage and you need to basically redo the entire thing, and then if you want to take it off completely, thats a totally different story

the tiles look good but are not very cost effective at all

personally i dont have a problem with the bare concrete as its easy to clean up oil/other stuff and it generally keeps pretty clean, although we usually dont have cars constantly coming and going in ours
