The most expensive floor is the one you have to replace!  Though it appears to be a big money saver to purchase a DIY epoxy garage floor kit from your favorite home improvement store, some quick research will show differently.  Though inexpensive, this is the least durable of epoxy garage floor coatings to apply. They are based on older formulations and are not the best value for your dollar. Their resistance to stains and chemicals are not as good as other types of garage floor epoxy and they are susceptible to hot tire lift.  After time, sometimes as little as 3 months, the floor peels, flakes and chips off and what is left? A failed garage floor coating that looks worse than before it was applied.  If is best to do it right the first time.
