Just get ceramic tile and be done with it. Picked up 12 x 12 tile in Mexico for .50 cents each, used half thickness of thinset with tight joints, been down for ten years. Run fork lifts around on it and drive 50,000 lb motorhome on it with no problems. Do half of garage and move stuff and do rest. I cut tile around two post lift, lathe. and bridgeport mill, four post lift sets on top of tile, no problem
