A two-car garage isn't a gallon of paint. Here's how to think about an epoxy or polyaspartic floor. First measure the length and width. Then plan the coats: often a primer, a body coat, and a topcoat. Decorative flake, if you want it, goes into the body coat. The part that makes or breaks the job is surface prep. The slab has to be clean, profiled, and dry enough, or the coating won't stick. Moisture in the slab is a common reason coatings fail. Standard epoxy wants a reasonably warm slab. Some polyaspartic systems can go on colder, but always check the product data sheet. Size the job with the epoxy calculator at concretenear.com, then find a local coating crew.
