I have a 30x30 garage/shop. I have an idea to paint the concrete floor
a beige eppoxy then put a 3 foot tall borger or "splash guard" around
the wall of tile. Maybe using a "checkered" pattern of beige and white
12x12 tiles.

Or painting the floor an epoxy gray and just using gray tiles/ (No
checkered pattern).

I know I have seen these wall tiles in a garage but did a search to
show my wife and came up empty. (She cant envision waht I am talkign
about).

What do you guys think?
