I have always wanted a sexy industrial concrete floor, and I am having one put in (or overlaid to fix the original one that was painted a puke peachy color) as I write. Am I getting exactly what I have been looking for? No, not with my budget. But I am trying to get as close as possible. Here are some of the images I used as reference to get across what I'm after.
