Concrete Polishing & Resurfacing in Ontario
Concrete polishing and resurfacing in Ontario
Polishing and resurfacing cover two different fixes for tired or damaged concrete. Polishing grinds down the existing slab with progressively finer diamond-impregnated pads, exposing aggregate if you want that look, then densifies and buffs the surface to a matte, satin, or high-gloss sheen. It works on structurally sound concrete and is common in garages, showrooms, warehouses, and basements where the slab itself is fine but the surface is dusty, stained, or dull. Resurfacing goes a step further: a cementitious or polymer-modified overlay gets applied to a slab that's cracked, pitted, spalled, or uneven, giving you a new wearable surface instead of a full tear-out and repour.
When comparing contractors in this category, ask how they handle moisture testing before overlay work (a big cause of bond failure if skipped), what grit sequence and number of passes they use for polishing, and whether they carry a densifier and stain guard as separate steps rather than one quick pass. Get a clear answer on how they deal with existing cracks or control joints, since a resurfacing job that ignores them will telegraph the same cracks back through in a year or two. Written warranties on adhesion and wear are worth asking for directly.

Common questions about concrete polishing & resurfacing
- How much does concrete polishing or resurfacing cost in Ontario?
- Basic polishing typically runs lower per square foot than resurfacing, since resurfacing involves material and labor to build up a new surface. Price depends on square footage, slab condition, the level of gloss or aggregate exposure wanted, and how much crack or joint repair is needed before work starts. Get at least three quotes based on an in-person assessment rather than a phone estimate, since slab condition varies a lot job to job.
- How often does a polished or resurfaced concrete floor need to be redone?
- A properly polished floor with routine cleaning and periodic re-application of guard or sealer can last many years before it needs another pass, since you're working with the original slab rather than a coating that wears off. Resurfaced overlays hold up well in normal traffic but can need touch-ups sooner in high-abrasion areas like garages or commercial kitchens, especially if the overlay wasn't properly bonded or sealed.
- What should I expect during the job?
- Expect dust and noise during grinding (reputable crews use dust-collection vacuums attached to the grinders, not just a broom), a curing or drying period between overlay coats if resurfacing, and a walkthrough at the end to check for consistent sheen and no soft or hollow spots. Garages and basements usually need to be cleared out beforehand and kept vehicle-free for a specified cure time after.
- How can I judge the quality of a finished job?
- Look for an even, consistent sheen across the whole floor with no hazy patches or grinder swirl marks, no visible seams or ridges at overlay edges, and no dusting on the surface within the first few weeks (a sign the densifier step was skipped or rushed). Ask to see photos of past jobs at a similar gloss level, since a contractor who mainly does low-sheen basement floors may not have the equipment or experience for a high-gloss showroom finish.
