This process brings back memories...
I looked into the plastic tile route but I personally didn't like them. They look great but I didn't like the clicky sound and they lack a solid feel, IMO.
I really wanted polished concrete but couldn't find a vendor in my area who would do such a small space.
Business must be good for those guys.
I settled on a professionally installed epoxy floor with the confetti. It looks good, feels good and no lifting. BUT, where my tires sit, the epoxy discolors into an
oil shade. It's not lifting, not soft or different in feel, just looks ugly. And I didn't park on it for months after installation. The epoxy seems to be leaching 'stuff' from the tires, either BB's or Avons or a dolly's tires (rubber in general). I feel like making the installer do it over but what a pain in AZZ!
Good luck.
