Thanks dudes. The floor was definitely not done by me. The guys that did it were impressive - they ground down the floor with big diamond grinders, patched the little cracks and holes, laid the epoxy down, saturated it with color chips, removed the excess chips after it all dried, and put a clear coat on top. All in one day! If anyone in Atlanta wants a referral, let me know.
I did paint the walls gray, though, so I guess I can take credit for that.
