Concrete Polishing & Resurfacing in Toronto

Concrete polishing and resurfacing covers two related but different jobs. Polishing grinds down an existing slab in progressive steps, using diamond-tipped tooling, to expose aggregate and bring up a glossy or satin finish without adding material. Resurfacing goes the other direction: it applies a new cementitious or polymer-modified layer over a slab that's cracked, pitted, or too far gone to grind, giving you a fresh surface without a full tear-out. Both are common across Toronto in garages, basements, retail floors, warehouses, and condo amenity spaces where a durable, low-maintenance finish beats tile or paint.

Before hiring anyone, ask how they handle moisture testing and crack repair before any grinding or coating starts. A floor that looks fine on day one can fail within a year if moisture vapor wasn't checked or if cracks were skimmed over instead of routed and filled. Ask what grit sequence they use for polishing, whether densifier and guard are applied as separate steps, and what warranty covers delamination or hazing. Get a firm sense of drying and cure times too, since rushing a resurfacing job is one of the most common causes of early failure.
