Garage Floor Coating in markham

Garage floor coating means grinding or acid-etching the existing concrete, patching cracks and pits, then applying epoxy, polyaspartic, or a hybrid system in one or more coats, usually finished with color flakes and a clear topcoat for grip and UV resistance. Markham's concrete is exposed to road salt, winter tire moisture, and temperature swings, so the prep work and the moisture testing done before coating matter as much as the product itself. We track 9 businesses in this category that handle this work for homeowners and property managers across the city.

What to look for before you hire

The biggest quality gap in this trade is surface prep. A company that grinds the slab with diamond tooling and checks for moisture vapor will outlast one that just etches with acid and rolls on a thin coat. Ask what system they use (polyaspartic cures faster and handles temperature swings better than standard epoxy), how many coats are included, whether crack repair and hot tire lifting are covered under warranty, and how long the garage needs to stay clear before you can park. Get a written warranty term and find out if it covers peeling or just fading.

How our scoring works

We weigh review consistency, how companies handle prep and warranty questions, and patterns across jobs rather than a single testimonial.
