ConcreteShield is a concrete polishing contractor based in Etobicoke, serving Toronto and the GTA. We grind, densify and polish existing concrete in homes, shops, offices and warehouses to a matte, satin, semi-gloss or high-gloss finish. Most floors cost $3–6 per sq ft installed.
What Is Concrete Polishing?
Concrete polishing is a precision grinding process that exposes the natural beauty of concrete, creating a high-gloss, reflective finish with no thick topcoat — only a penetrating densifier and guard. Using diamond abrasives, we grind the concrete surface to reveal aggregate (stones), resulting in a stunning, durable, low-maintenance floor.
Polished concrete is ideal for modern commercial spaces, retail showrooms, corporate offices, and upscale residences. It's eco-friendly, needs no thick topcoat — only a penetrating densifier and guard, and improves lighting efficiency by reflecting light naturally.
If you've searched for concrete polishing Toronto, concrete floor polishing services, or a concrete polishing company serving the whole GTA, ConcreteShield is a dedicated polished concrete floors contractor serving the entire region — not just downtown Toronto. We bring the same diamond-grinding equipment and precision process to Etobicoke, Vaughan, Markham, Oakville, and every surrounding GTA community, with fully custom gloss levels for every project.

The Concrete Polishing Process
Concrete polishing transforms ordinary concrete into beautiful high-gloss flooring. Our multi-step diamond-grinding process gradually exposes the aggregate in concrete, creating a durable, stain-resistant finish that needs no thick topcoat — only a penetrating densifier and guard.
Polishing Process Steps
- 1 Surface Assessment — Inspect concrete for cracks, damage, and staining. Repair deep cracks and remove stains. Assess surface profile to determine appropriate polishing level.
- 2 Coarse Grinding — Start with 50-80 grit diamond pads to remove surface coatings, stains, and level the floor. Creates proper profile for aggregate exposure.
- 3 Medium Grinding — Progress to 150-250 grit pads to further refine and begin exposing aggregate stones. Creates more visual depth and interest.
- 4 Fine Grinding — Use 400–1,500+ grit pads to reach the chosen shine level: matte, satin, semi-gloss, or high-gloss (800–1,500+ grit). Aggregate is beautifully exposed.
- 5 Sealing & Protection — Apply food-grade sealer (if needed) or protective sealer. Enhances shine, protects against staining, and makes cleaning easier.

Gloss Levels Explained
The shine on a polished floor comes from how far we take the grind, not from a coating. Each step uses a finer diamond, and the last grit you stop at decides how much light the floor reflects. Here is how the four common levels compare and where each one works best.
| Finish | Final grit (approx.) | Look | Where it suits |
|---|---|---|---|
| Matte | Up to about 200 | Flat, low sheen, hides dust and footprints | Warehouses, workshops, garages and back-of-house areas |
| Satin | About 200–400 | Soft sheen with a clean, honed look | Basements, offices, schools and busy retail aisles |
| Semi-gloss | About 400–800 | Clear reflection of overhead lights | Showrooms, restaurants, lobbies and modern living spaces |
| High-gloss | 800–1,500+ | Mirror-like shine and the most light reflection | Car and furniture showrooms, galleries and feature floors |
Gloss is only half the look. The other half is how much of the stone inside the slab shows. A cream finish barely touches the surface paste, so the floor stays an even grey. A salt-and-pepper finish cuts slightly deeper and shows fine sand and small specks of stone. A full exposed-aggregate finish grinds deeper again to reveal larger stones; it takes the most time and costs the most. Higher gloss also shows scratches and grit sooner, so in busy commercial entrances we often recommend satin or semi-gloss with walk-off mats.
Concrete Polishing Cost in Toronto & the GTA
Most polished floors in Toronto and the GTA cost $3–6 per square foot installed. Where your floor lands in that range depends on what we find when we test the slab. These are the things that move the price:
- •Slab condition: old paint, glue, tile adhesive or sealers have to come off before polishing starts, which adds grinding passes.
- •Crack and joint repair: cracks, spalls and control joints are filled before the polish so they don't chip at the edges.
- •Gloss level: every extra grit step is another full pass over the floor, so high-gloss costs more than matte or satin.
- •Square footage: larger open floors cost less per square foot because set-up time is spread over more area; small rooms with many corners cost more.
- •Grind depth: a cream finish is quickest; salt-and-pepper and exposed aggregate need deeper, slower cuts.
- •Densifier and guard: every floor gets a densifier to harden the surface; a stain guard is added for kitchens, garages and retail floors.
Typical scope by floor type
| Floor type | Typical scope |
|---|---|
| Newer home or condo slab | Light grind, densify, polish to satin or semi-gloss, stain guard |
| Older basement slab | Remove paint or adhesive, fill cracks, moisture check, grind, densify, polish, guard |
| Garage slab | Degrease, repair salt pitting and cracks, grind, densify, polish to matte or satin, stain guard |
| Retail store or office | Fill joints, grind to cream or salt-and-pepper, polish to semi-gloss or high-gloss, guard |
| Warehouse or shop floor | Large-area grind, fill joints, densify, polish to matte or satin; larger areas lower the per-foot cost |
Every quote is fixed and written after a free site visit, so you know the full price before any work starts. Indoor residential floors carry a 10-year warranty and commercial floors 2 years — see the warranty page for what is covered.
Polished Concrete vs Epoxy
Both start with a diamond grind, but they end very differently. Polishing refines the concrete itself; epoxy puts a new resin surface on top of it. This is how they compare on the points customers ask about most.
| Polished | Epoxy coating | |
|---|---|---|
| Installed cost | $3–6 per sq ft | $5–9 per sq ft |
| Lifespan | 10+ years with resealing every 1–2 years | 15–20 years residential, 10–15 years commercial |
| Slip resistance | Good when dry; can be slick when wet unless treated | Anti-slip aggregate can be mixed into the topcoat |
| Maintenance | Dust mop, pH-neutral cleaner, reseal every 1–2 years | Mop with mild cleaner; recoat the topcoat when worn |
| Best for | Sound slabs in retail, offices, warehouses and modern homes | Damaged slabs, garages, kitchens and colour or flake finishes |
| Downtime | 1–3 days; usable as soon as the work is done | Walk on after 24 hours, full use after 3–5 days |
Polishing is the better choice when the slab is in good shape and you like the look of concrete. If the slab is badly cracked or stained, or you want a colour, flake or metallic finish, a coating usually makes more sense — see our page on epoxy floor coating in Toronto. People also ask about sealed concrete: a sealer is a thin film rolled onto unground concrete, so it wears off in a few years, while a polished floor is ground and densified, so the shine is part of the slab.
Polished Concrete for Toronto Garages & Basements
Garages: Toronto winters are hard on bare concrete. Road salt and slush drip off the car, soak into the surface and break it down from the top, which is why so many older garage floors are pitted and flaking. A polished, densified garage floor is much harder and less porous than raw concrete, so salt water sits on top long enough to be squeegeed out. Hot tires are not a problem either: there is no thick topcoat to soften and lift, so there is no “hot tire pickup”. We finish garages at matte or satin and add a stain guard so oil and brake fluid wipe up.
Basements: a polished basement is clean, bright and easy to keep up, and it pairs well with in-floor heating. Basement slabs are tested for moisture first. A polished slab still breathes, so it tolerates normal vapour better than a coating does, but active water leaks have to be fixed before any finish goes down.
Commercial floors: a polished floor is a natural fit for retail stores and showrooms that want a bright, modern floor, offices and lobbies where a low-maintenance finish matters, warehouses where forklifts and pallet jacks would wear through a thin coating, and restaurants front-of-house where a guarded floor handles spills. We polish commercial floors across the city — see our Toronto, Vaughan and Markham service pages for local details, or browse our commercial projects.
For occupied buildings we can work in sections, at night or over weekends, so stores and offices stay open while the floor is done.
Why Hire a Concrete Polishing Contractor in Toronto
Rental grinders and DIY kits can take the top off a floor, but a true polish needs the right machines, the right sequence of diamonds and a lot of experience reading the slab.
Professional equipment
We use heavy planetary grinders and edge machines with a full set of metal and resin diamonds, so the floor is flat and evenly polished right to the walls, not just in the middle of the room.
Dust control
Dry grinding concrete releases fine silica dust. Our grinders connect to dust-extraction vacuums with HEPA filtration, which keeps your home or business clean and protects everyone in the building.
Slab testing first
Before quoting we check hardness, flatness, moisture and old coatings. Very soft or heavily damaged slabs are better served by a coating, and we will tell you so instead of selling a polish that won't look right.
Repairs and densifier done right
Cracks and joints are filled at the right stage, and the densifier is applied at the right grit so it soaks in and hardens the surface. Get this wrong and the floor can look patchy or dust over time.
Is your floor a good candidate? Most slabs in sound condition polish well, including older ones. Floors with heavy cracking, a weak surface or patches of different concrete will look uneven when polished and usually suit a coating instead. A free site visit settles it.

Concrete Polishing FAQs
What is concrete polishing exactly?
Concrete polishing uses diamond-grinding equipment and progressive abrasives to expose the aggregate (stones) in concrete, creating a high-gloss, reflective finish. It's the concrete itself that's polished, with no thick topcoat — only a penetrating densifier and guard.
How long does polished concrete last?
Polished concrete lasts 10+ years without peeling or fading. With no thick topcoat — only a penetrating densifier and guard, there is nothing to peel. With resealing every 1–2 years, the shine remains pristine for decades.
Is polished concrete safe for commercial kitchens?
Yes. Polished concrete with food-grade sealer is NSF-approved for commercial kitchens. It resists bacteria, is easy to sanitize daily, and meets health code requirements. We can add non-slip treatments if needed.
How much does concrete polishing cost?
Polished concrete typically costs $3-6 per square foot installed in the GTA. Costs depend on concrete condition and gloss level. We provide transparent quotes after site assessment with no hidden fees.
What's the difference between polished concrete and epoxy?
Polished concrete is the concrete itself polished to high gloss—with no thick topcoat — only a penetrating densifier and guard. Epoxy is a protective coating applied over concrete. Epoxy has the longer coating life (15–20 years in homes); polished concrete has lower upkeep, with nothing to peel and resealing every 1–2 years. Epoxy also offers more colour options.
How do you maintain polished concrete?
Sweep or dust mop regularly. Clean with pH-neutral cleaner and soft mop. Avoid acidic cleaners (lemon, vinegar). Reseal every 1–2 years to maintain shine and protect against stains and spills.
Can existing stained concrete be polished?
Yes. Most concrete can be polished, even stained or worn concrete. We assess the condition first and repair any cracks or spalling. The polishing process removes stains, revealing clean, beautiful concrete beneath.
Is polished concrete slippery?
Yes, polished concrete can be slippery when wet. We can add non-slip treatments, apply slip-resistant coatings, or use lower gloss levels. For commercial kitchens and retail, we recommend non-slip measures.
How is concrete polishing eco-friendly?
No chemicals or toxic coatings used. Leverages existing concrete, reducing waste. Reflective surface reduces artificial lighting by 15%, lowering energy consumption. Perfect for LEED-certified and green-building projects.
