Residential epoxy flooring covers garage floors, basements, workshops, and sometimes interior living spaces where homeowners want a durable, easy-to-clean surface instead of bare concrete or worn tile. The process usually starts with grinding or shot-blasting the existing concrete to open its pores, patching cracks and low spots, then applying a primer, one or more epoxy base coats, and a topcoat (often polyaspartic or polyurethane) for UV stability and scratch resistance. Decorative flake or metallic finishes get broadcast into the wet coat before the final seal. We list 10 companies in Markham that do this kind of residential work.
Quality varies a lot in this trade because so much of it happens below the visible finish. Moisture testing before installation, proper surface profiling, and correct cure times between coats matter more than how glossy the final result looks on day one. A cheap job that skips prep can bubble, peel, or delaminate within a year or two. When comparing contractors, ask about their surface prep method, the coating system they use, warranty terms, and whether they carry insurance for in-home work.
