Another option, Garage Snap Tiles. Very durable. Have had these for 12 years. Good as new. Only maintenance is a mop a couple of times a year. Hard plastic tile that lays over existing floor. Not as pretty as good epoxy job but it is a garage. Can be a do it yourself job but some edge cutting necessary at walls. We chose to get ours installed so no surprises.
