The typical epoxy floor kits you get at the big box store won't hold up over time to acids, petroleum products, or high heat, like a hard run motorcycle tire. My neighbor came pulling into his garage after a hard run on his motorcycle and pealed up a strip of the cheap stuff around his back tire.
To do it right, I use two versions of the PPG Aquapon two part epoxy. Clean, sand and acid etch the floor to get all of the contaminates off, then rinse thoroughly and let dry. The cleaner, the better. Your base coat should be with the water based Aquapon (?). The top coat should be with the solvent based Aquapon (35). These two products are compatible with each other. The water based Aquapon will flow into the micro-pores of the concrete and reduce/eliminate bubbling. The top coat, solvent based, epoxy is impervious to almost anything. Follow all directions, vent well, and use a respirator. This stuff is used to coat pipes that are immersed in sea water and will handle solvents and battery acid.
My house garage floor is going on 20+ years and still sealed. It does have some stains in it, but the integrity is still good after all of this time.
Here's my new toy shop with the Aquapon treatment. I love my central heating and air system!
