Concrete Grinding & Coating Removal in Thornhill
In Thornhill, much of our grinding work is removal: old coatings in garages of mid-century homes and larger family homes with attached garages and finished basements, and glue, mastic and failed coatings in the units and buildings of plazas.
We remove coatings and adhesives with dust-controlled diamond grinding, take down high spots and joint lips, and leave the Thornhill slab clean and profiled, ready for epoxy, polishing or a sealer.
Call (647) 370-9166 or send the form on this page for a free concrete grinding quote in Thornhill. Send the approximate square footage and a few photos, and we will come back with a written quote that lists the prep, the system, the number of coats and the schedule.
The system
Concrete Grinding & Coating Removal
Before a new floor can go down, the old one often has to come off. Peeling epoxy, paint, DIY garage kits, carpet and tile glue, thinset and mastic all prevent a new coating from bonding. We remove them with heavy diamond grinders and, where needed, scrapers, leaving clean, open concrete ready for the next finish.
Grinding also flattens high spots and lips at joints, removes the weak top layer of the slab, and creates the surface profile that epoxy and polyaspartic coatings need to bond mechanically. It is the single most important step in a lasting coating, and the one most often skipped.

Questions
Concrete Grinding & Coating Removal in Thornhill: FAQs
How do I get a concrete grinding & coating removal quote in Thornhill?+
Call (647) 370-9166, use the form on this page or email info@trueformepoxy.ca. Send the approximate square footage and a few photos and we will send a written quote for your Thornhill project.
Can you remove a peeling DIY garage coating?+
Yes. Failed DIY kits are one of the most common things we grind off. Once the old coating is removed and the slab is properly profiled, a professional system can be installed in its place.
Is grinding dusty?+
We use dust-controlled grinders connected to industrial vacuums, which capture most of the dust at the source. There is some noise, so we schedule around occupied spaces.
Why not just acid-etch the floor?+
Acid etching does not remove contaminants, sealers or old coatings, and it leaves an inconsistent surface. Diamond grinding gives a clean, even profile the coating can grip, which is why we use it for every coating job.
Do you offer concrete grinding & coating removal across Thornhill?+
Yes. We work throughout Thornhill, including Thornhill Village, Bayview Glen, Thornhill Woods, Brownridge, Grandview, Royal Orchard and German Mills, and in nearby Vaughan, Richmond Hill, Markham, Woodbridge and Scarborough.
