The Best Floor Coating for Every Space, Toughest First
Short answer: the strongest floor we install is 1/4" urethane cement with a polyurethane top coat, and it's what commercial kitchens, food plants and auto shops need. Garages get a polyaspartic (polyurea) flake system. Warehouses and big industrial spaces get two coats of industrial epoxy. Showrooms get metallic epoxy or polished concrete. Every room is different, so pick yours below.
What's your space?
Commercial kitchen: we'd install
Urethane cement, 1/4" with a PU top coat
Dropped knives and pans, boiling water and degreaser every night. Urethane cement takes the impact and the heat, gets a gritty top coat for wet floors and a cove at the walls.

What decides the system
There's no single best floor, only the right one for what the floor has to survive. We pick by six things:
- Impact. What gets dropped on it: knives and pans, wrenches, pallets.
- Heat. Hot water, steam cleaning, hot oil, hot tires.
- Chemicals. Grease, food acids, salt, brake fluid, cleaners.
- Moisture. How damp the slab is underneath. We test before we quote.
- Downtime. How long you can be closed, and whether we work in sections or after hours.
- Looks and budget. A showroom and a service bay don't need the same floor.
All five systems side by side
Ranked toughest first. Swipe the table sideways on a phone.
| Urethane cement | Polyaspartic | Industrial epoxy | Metallic | Polished | |
|---|---|---|---|---|---|
| Toughness | Toughest system we install | Toughest thin coating; our garage system | Best value for big spaces | The showpiece | Nothing to peel, ever |
| Thickness | 1/4" (about 6 mm), troweled | Thin multi-coat system with a full flake broadcast | Two coats of solid industrial epoxy | Epoxy with metallic pigments, protective top coat | No coating: the slab itself, ground, densified and polished |
| Dropped tools / knives | Highest. A dropped knife, pot or wrench won't chip it | Very good for a thin coat; flake hides marks | Good; heavy dropped steel can chip it | Good; scratches show more on dark, glossy colours | As strong as your concrete; can't chip a coating that isn't there |
| Heat / hot water | Built for hot-water washdowns and hot spills | Hot tires, sun through the door (non-yellowing, full UV per LabSurface) | Not for hot-water washdowns; yellows in direct sun | Indoor only | Fine |
| Resists | Grease, food acids, oils, cleaners | Road salt, oil, gas, brake fluid | Oils and most cleaners | Household and light commercial spills | Oil and acids can stain it unless it's sealed |
| Damp slab | More tolerant than epoxy; we test the slab first | Needs a sound, dry slab | Needs a dry slab, or a moisture barrier first | Moisture barrier first (every indoor job) | Not an issue; it breathes |
| Back in use | Set per product and temperature; exact time in your quote | Walk on it in 24 h, drive in 48 h, full cure 2 weeks (LabSurface, room temp) | Walk on it in 24 h, light traffic 36–48 h, full cure 1 week (LabSurface, room temp) | Walk on it in 24 h; we confirm the full cure for your temperature | Usually back in use right after we finish a section |
| Looks | Solid colour, matte, textured for grip, coved up the walls | Flake blends in many colours, gloss or matte | Solid colour, gloss, safety lines and zones | Marble, lava, pearl or ocean effects; no two floors alike | Satin to high gloss, shows the concrete's character and any cracks |
| Price | Quoted per job | $2,800–$3,400 for a 2-car garage | $3.50–$5/sq ft, about $4.25/sq ft from 1,500 sq ft | from $14/sq ft | from $7/sq ft |
| Best for | Commercial kitchens, food prep, breweries, auto shops | Garages, also the top coat on our basement and commercial flake floors | Warehouses, industrial units, storage, back-of-house | Showrooms, retail, salons, offices, high-end basements | Large showrooms, retail, warehouses, offices |
| Not for | Spaces where the look matters more than toughness | Boiling-water washdowns and heavy dropped-tool abuse | Kitchens with hot washdowns; spaces in full sun | Working floors with carts, tools or grit | Kitchens and service bays (stains); slabs in rough shape |
Cure times and UV rating are LabSurface's published figures at room temperature; colder means longer. Commercial prices are guide ranges; every job gets its own quote after we see the slab.
Urethane cement, 1/4" with a PU top coat
Urethane cement (also called PU cement or polyurethane concrete) is a cement and polyurethane resin blend troweled down at about a quarter inch, then sealed with a polyurethane top coat. That thickness is the difference. A thin coating is a skin on the concrete; this is a new wearing layer on top of it.
It's the system for floors that get abused: a chef's knife or a cast-iron pan dropped on the line, a wrench or a jack stand dropped in a service bay, boiling water and degreaser at closing every night. Thin epoxy chips, cracks and lets go under that. Urethane cement takes it. It also handles a damper slab than epoxy does, which matters in older buildings and on slabs without a vapour barrier.
We finish it with a textured top coat for grip on wet, greasy floors and run it up the walls as a cove, so there's no seam at the wall for water and food to collect in. Health inspectors like that, and so do the people mopping it.

Polyaspartic / polyurea flake system
Polyaspartic is a type of polyurea. Pure polyurea sets in seconds and has to be sprayed; polyaspartic is the version that gives us time to roll it on properly, then cures fast and hard. Most garages we do get a full polyaspartic system: a pigmented base, a full flake broadcast and a clear top coat. No epoxy in it.
It stays clear in the sun, stands up to salt and hot tires, and the flake hides the scuffs a garage collects. It's the toughest thin coating we put down, and it's the top coat we put over flake on basements and commercial floors too.
- Best for
- Garages, also the top coat on our basement and commercial flake floors
- Not for
- Boiling-water washdowns and heavy dropped-tool abuse
- Price
- $2,800–$3,400 for a 2-car garage
Industrial epoxy, two coats
For a warehouse or industrial unit, two coats of solid industrial epoxy is the workhorse: a bright, sealed, easy-to-sweep floor that resists oil and most cleaners, with lines and zones painted in. Per square foot it's the best value we offer, and the price drops as the space grows.
Where it's the wrong pick: hot-water and steam cleaning (thermal shock cracks it), heavy steel dropped on it all day (it chips), and spaces in full sun (standard epoxy ambers). That's when we move up to urethane cement or a polyaspartic top coat.
- Best for
- Warehouses, industrial units, storage, back-of-house
- Not for
- Kitchens with hot washdowns; spaces in full sun
- Price
- $3.50–$5/sq ft, about $4.25/sq ft from 1,500 sq ft
Metallic epoxy
Metallic epoxy is about the look: pigments that move in the wet resin and set into marble, lava or ocean effects. It's a showroom and front-of-house floor. It's tough enough for foot traffic and customers, but it's not what you put under a hoist or a prep line, and scratches show more on dark, high-gloss colours. We finish it with a protective top coat.
- Best for
- Showrooms, retail, salons, offices, high-end basements
- Not for
- Working floors with carts, tools or grit
- Price
- from $14/sq ft
Polished concrete
Polished concrete isn't a coating. We grind the slab with diamonds, harden it with a densifier and polish it up to the shine you want. With no layer on top, there's nothing to peel, chip or recoat, which is why big showrooms and warehouses pick it for low upkeep over thousands of square feet.
The trade-off: it shows the slab as it is, cracks and patches included, and oil and acids can stain it if it isn't sealed. We polished an 8,000 sq ft commercial showroom in Burlington; the service area in the same building has an epoxy floor we put down about three years earlier.
- Best for
- Large showrooms, retail, warehouses, offices
- Not for
- Kitchens and service bays (stains); slabs in rough shape
- Price
- from $7/sq ft
Spaces we looked at this fall
Real GTA spaces from our site visits and quotes, and the system each one called for:
Auto service shop, Mississauga, about 3,700 sq ft
Service bays with lifts, dropped tools and fluids every day: the kind of floor that needs urethane cement, not a thin coating.
Warehouse, North York, about 3,400 sq ft
Old floor paint ground off, cracks and joints repaired, two coats of industrial epoxy in a solid colour, and an epoxy cove base along 110 ft of wall so the floor sweeps and mops clean.
Industrial unit turning into a car storage showroom, 2,400 sq ft
Two coats of solid industrial epoxy: the commercial-grade floor most shops and units go with.
Basement clinic, Etobicoke, about 800 sq ft
A moisture barrier first because it's below grade, then an epoxy base, flake and a polyaspartic top coat: easy to disinfect and comfortable underfoot.
Why kitchens and service bays shouldn't get plain epoxy
It's the most common mistake we see. Epoxy looks great on day one, so it gets put everywhere. In a kitchen, the nightly hot-water washdown heats and cools the floor over and over; a thin, rigid coating can't move with the concrete, so it cracks and lifts at the drains and walls first. In a service bay, every dropped wrench takes a chip out. Once water gets under the coating, it peels in sheets.
Urethane cement costs more up front, but you're not closing the restaurant to redo the floor in two years. For the spaces that need it, it's the cheaper floor.
Prep is the same on every system
Whatever goes on top, it's only as good as the bond. Every floor starts with diamond grinding, so the system bonds into the concrete instead of sitting on it, then cracks, holes and low spots get filled and ground flush. Indoors, we test the slab for moisture and put down a moisture barrier where the system needs one. 25 years in epoxy, our own company since 2019, WSIB covered.
Questions owners ask
What is the strongest floor coating?
Of the systems we install, 1/4" urethane cement with a polyurethane top coat. It's about ten times thicker than a thin coating, takes dropped knives and tools without chipping, and handles boiling-water washdowns. It's what we put in commercial kitchens, food plants and auto shops. For a thin coating, polyaspartic is the toughest.
Is epoxy good for a commercial kitchen?
Not as the main system. Kitchens get hot-water and steam cleaning every day, and that thermal shock cracks thin epoxy and lets it lift; dropped pans and knives chip it. Urethane cement is built for exactly that, so it's what we recommend for kitchens.
Urethane cement vs epoxy: what's the difference?
Thickness and toughness. Epoxy is a thin coating that's great value on big dry floors like warehouses. Urethane cement goes down at about 1/4", handles impact, heat and a damper slab, and costs more. Pick by what the floor has to survive.
What's the difference between polyaspartic and polyurea?
Polyaspartic is a type of polyurea. Pure polyurea sets in seconds and has to be sprayed; polyaspartic sets slower, so it can be rolled on evenly, and it stays clear in sunlight. It's the system we use in garages and as the top coat on our flake floors.
What's the best floor for an auto shop?
Urethane cement with a polyurethane top coat. Service bays get dropped steel, jack stands, oil and hot fluids, and that's the system that survives it. For a lighter-use bay or a detail shop, an industrial epoxy or a polyaspartic flake floor can work.
Polished concrete or epoxy for a showroom?
Both work. Polished concrete never peels and costs less to keep up over a big space, but it shows every crack and patch in the slab. Metallic or solid epoxy covers the slab and gives you colour and a showpiece look.
How long will my business be closed?
It depends on the system, the size and the temperature. Epoxy and polyaspartic take foot traffic after about 24 hours at room temperature; polished concrete can often be used right after each section is done. We give you the exact schedule in the quote and can work in sections or after hours.
Do you do coving and drains?
Yes. Kitchens and washrooms usually get a cove base so the floor runs up the wall with no seam, and we slope and finish around floor drains. It's priced in your quote.
Are you insured for commercial work?
WSIB covered, and we provide an insurance certificate on request for jobs that need one. Projects of any size.
