Concrete floor grinding and surface preparation in Toronto by Butterfly Floorings

What Is Concrete Floor Grinding?

Professional Floor Grinding
Across Toronto GTA

Concrete floor grinding uses industrial diamond tooling to mechanically abrade the concrete surface, removing existing coatings, adhesives, high spots, and contamination. It is the single most important step in any flooring project — no coating system, however premium, will bond to an unprepared surface. Butterfly Floorings provides professional floor grinding across Toronto, Mississauga, Brampton, Oakville, and the entire GTA.

We use professional-grade planetary grinders and diamond tooling calibrated for your specific concrete hardness and project requirements. Whether you need light surface profiling for a new epoxy coating or full removal of thick existing coatings, we have the equipment and expertise to do it right.

Grinding Applications

When You Need
Floor Grinding

Surface Prep Before Epoxy or Polishing
Every epoxy and polishing project begins with diamond grinding. We prepare your floor to the correct CSP (Concrete Surface Profile) to ensure maximum adhesion. Whether you're getting epoxy flooring in Toronto or concrete polishing, grinding is the essential first step.

Old Coating Removal
Removing failed epoxy, paint, mastics, adhesives, and VCT glue from existing concrete floors. We strip back to bare concrete cleanly and efficiently, leaving a fresh surface ready for a new flooring system.

Concrete Restoration & Leveling Prep
Grinding down high spots, removing damaged surface layers, and preparing uneven concrete for leveling compounds or overlay systems. Ideal for warehouse floors, retail units, and residential renovations across the GTA.

Our Process

Our Concrete Grinding
Process

01
Floor Assessment

We assess concrete hardness, existing coating thickness, contamination type, and project goals to select the correct diamond tooling and grinder configuration before starting any work.

02
Diamond Grinding

Industrial planetary grinders with diamond tooling systematically remove coatings, profile the surface, and eliminate high spots. Dust is managed with industrial vacuum systems throughout.

03
Profile Verification

We verify the concrete surface profile (CSP) meets the specification required for the intended coating or polishing system. Crack and joint repairs are completed at this stage.

04
Ready for Next Step

Your floor is now clean, profiled, and ready for epoxy coating, polishing, leveling, or any other flooring system. We can proceed with the next stage or hand off a prepared surface to your installer.

Common Questions

Concrete Grinding FAQs
Toronto & GTA

How much does concrete floor grinding cost in Toronto?
Concrete floor grinding in Toronto typically costs between $1.50 and $4.00 per square foot depending on the number of passes required, coating thickness being removed, and floor condition. We provide free on-site assessments — contact us for an accurate quote.
Is concrete grinding dusty? How do you manage dust?
Concrete grinding produces significant dust if not controlled. We use industrial vacuum systems with HEPA filtration connected directly to our grinders to capture dust at the source. The work area is kept clean and neighbouring spaces are protected throughout the job.
Do I need concrete grinding before epoxy or polishing?
Yes — always. No coating or polishing system will properly bond to unprepared concrete. Surface grinding is the most critical step in any flooring project. Skipping it or using acid etching instead is the number one reason epoxy floors fail within a few years.
Can you grind floors in occupied commercial spaces?
Yes. We can schedule work during off-hours, weekends, or in phased sections to minimise disruption to your operations. Our dust management systems make it practical to work in occupied retail, medical, and office environments across Toronto and the GTA.
Do you offer concrete grinding as a standalone service?
Yes. While most grinding work is done as part of a larger flooring project, we also provide grinding as a standalone surface preparation service for contractors and property managers who are supplying their own coating or working with another installer.
