Garage floor coating turns bare, dusty concrete into a sealed surface that resists oil stains, road salt, tire marks and moisture. Most jobs in Hamilton involve grinding or acid-etching the slab to open the pores, patching cracks and pits, then applying a base coat (usually epoxy) followed by a topcoat that's either epoxy, polyaspartic, or a polyurea/polyaspartic hybrid. Decorative color flake or quartz broadcast into the base coat is common for garages, both for grip underfoot and to hide small imperfections. We're tracking 6 installers who do this work across Hamilton and the surrounding area.
Not all coatings are equal, and the difference between a floor that lasts 10-15 years and one that peels within a winter usually comes down to prep work and moisture testing rather than the brand of product used. When comparing installers, ask how they handle concrete moisture (a calcium chloride or in-situ probe test matters), whether grinding is included or if they only acid-etch, what mil thickness they're applying, and what the warranty actually covers (delamination vs. staining vs. hot-tire pickup).
Our scoring weighs verified customer feedback, how consistently a company answers questions about their prep process and materials, response time, and business longevity. It's not a paid placement list. For the full breakdown of how each Hamilton company stacks up, see our ranked guide to Hamilton's best epoxy flooring companies.
