If you can imagine a paint for your garage floor that bonds like it's welded to the surface, resists oils, acids and just about anything else spilled on it, always looks like new and never wears off--you're probably thinking of epoxy. These finishes have been around for years, but epoxy is notoriously difficult to mix and apply, so in the past if you wanted an epoxy floor you were better off hiring a pro to do it.
Today there are do-it-yourself epoxy floor finish kits that are much easier to work with, and they offer an economical alternative to lower-cost floor paints and more-expensive mats or tiles.You still have to mix in a catalyst, and work quickly to prevent the material from drying before you complete the job, but the process is more forgiving and the results are just as professional-looking.
Epoxy floor finish kits include plastic grit particles that are sprinkled onto the wet finish to prevent slipperiness; these particles generally last longer and perform better (and look more attractive) than sand additives. As with paints and sealers, preparation of the concrete floor is all-important to ensure a permanent finish. --MM
