My choice is Benjamin Moore Industrial Floor Coatings because I sell it everyday. Epoxyman puts it right on the money! Prep, Prep, Prep and picking the right floor system for you. Many companies offer several floor systems for a reason. To much sunlight and a epoxy floor will dull/chaulk. To much standing water and urethane system will fail. Epoxy Mastix, the salemen saw you coming with a big check book. Existing coat may cause you to use waterbourneor 100 % solids. Some people like a 100% solids look. Me I like a combo sytem, primer , 100% solids with urethane for top coat. Remember Hot tire pickup will still leave a dull spot on 2 part system, even airplane hanger leave a rug under the tires for storage. Always, alway get a shec sheet on the product and study things like % to solids, pot life, induction time, surface temp., Wet film thickness vs. Dry film thickness and weather conditions. My 2 cents.
