One of the first things we do to the floors in our garages is to install an epoxy coating from UCoat It. Over the years we have tried different methods of flooring and UCoat It last the longest and is fairly easy to install yourself. For around $600 for the entire kit for a single bay it isn't cheap but we have yet to have any problems with any of the floors where we have used it. Figure on half a day to do the prep work, a full day for the base coats, and half a day for the finish coat. Most of that time is waiting for things to dry but don't rush it. UCoat It comes in many different color options but we chose beige with a turf UFlek-AF for our Waynesville garage. Next up is to paint the walls and change out the window treatments.
