Key points
- Ontario installed pricing runs $4 to $12 per square foot in 2026, with most residential garage work between $5 and $10. [1][3]
- Commercial grade 100% solids systems run $8 to $15 per square foot, and urethane cement for wash down environments sits at the top of that band. [1][2]
- ICRI Technical Guideline 310.2R-2013 defines ten concrete surface profiles, CSP 1 through CSP 10. High build epoxy and urethane coatings typically require CSP 3 to CSP 5. [5]
- ASTM F2170 calls for three in situ relative humidity probes across the first 1,000 square feet, plus one probe for each additional 1,000 square feet. [6]
- ASTM F710 references 75% internal relative humidity and 3 lb per 1,000 square feet per 24 hours as benchmark slab moisture thresholds, unless the manufacturer specifies otherwise. [6]
- Water based epoxy carries a 3 to 5 year service life against 8 to 12 years for 100% solids systems, which reverses its apparent price advantage. [2][7]
- Minor surface preparation adds roughly $1 to $2 per square foot. Full resurfacing of damaged concrete runs $3 to $7 per square foot on its own. [1]

What does epoxy flooring cost by system type?
In short: Resin chemistry is the largest line item after square footage, and installed pricing spans $2 to $15 per square foot across the common systems. The cheapest chemistry carries the shortest service life.
| System | Installed cost (CAD per sq ft) | Service life | Typical application |
|---|---|---|---|
| Water based epoxy | $2 to $5 | 3 to 5 years | Low traffic, budget projects |
| Solid colour epoxy | $4 to $7 | 5 to 10 years | Garages, basements, light commercial |
| Flake broadcast epoxy | $5 to $12 | 8 to 12 years | Showrooms, garages, slip resistance |
| Metallic epoxy | $8 to $15 | 8 to 12 years | Decorative retail and residential |
| 100% solids epoxy | $8 to $15 | 8 to 12 years | Warehousing, manufacturing, dealerships |
| Urethane cement | $8 to $15 | 15 years or more | Food and beverage, wash down, freezers |
Two things in that table matter more than the headline numbers. Water based epoxy looks inexpensive and rarely is, because a coating replaced twice inside ten years costs more than the system that lasted ten years. [2][7]
Urethane cement carries the highest per square foot figure and often the lowest cost per year of service. In a plant running wash down cycles or steam cleaning, epoxy alone will not survive the thermal shock, so the cheaper quote does not describe the cheaper floor.
What does epoxy flooring cost by space?
In short: A two car garage typically lands between $2,500 and $4,800, while a 10,000 square foot warehouse runs $60,000 to $120,000. Per square foot pricing improves as the job gets larger.
| Space | Typical size | Typical installed cost (CAD) |
|---|---|---|
| Single car garage | 250 to 300 sq ft | $1,200 to $2,000 |
| Two car garage | 400 to 500 sq ft | $2,500 to $4,800 |
| Finished basement | 700 sq ft | $2,100 to $5,000 |
| Retail floor | 2,000 sq ft | $10,000 to $24,000 |
| Warehouse | 10,000 sq ft | $60,000 to $120,000 |
Mobilization, grinding equipment, and crew setup are largely fixed costs. Spreading them across 20,000 square feet produces a meaningfully better rate than spreading them across a 2,000 square foot showroom running the same system.
Why is surface preparation the biggest variable in the quote?
In short: Preparation separates a floor that lasts a decade from one that peels in two winters, and it is where quotes diverge most. It is also the part of the specification most often left vague.
The International Concrete Repair Institute defines ten concrete surface profiles in Technical Guideline 310.2R-2013, running from CSP 1 at nearly smooth to CSP 10 with an amplitude greater than a quarter inch. High build epoxy and urethane systems generally call for CSP 3 to CSP 5, and most coating manufacturers void their warranty if the specified profile is not achieved. [5]
The practical question is not which preparation method appears on the quote but whether that method reaches the profile the coating requires. Each method produces a different profile range.
- Acid etching opens a light profile suited to thin sealers, densifiers, and low build coatings.
- Diamond grinding reaches roughly CSP 3, which covers many standard epoxy systems.
- Shot blasting and scarifying produce the deeper profiles required by high build systems and thick polymer overlays.
A specification that names the target CSP alongside the method is the one to trust. A quote that names neither is not a quote. It is an estimate of a floor nobody has assessed.
Beyond baseline profiling, the usual additions are:
- Minor preparation on sound newer slabs, roughly $1 to $2 per square foot. [1]
- Crack repair, spall patching, and joint treatment, priced as separate line items.
- Removal of a failed existing coating, which has to come off in full before anything new goes down.
- Full resurfacing of badly damaged concrete, $3 to $7 per square foot on its own. [1]
Does the slab need a moisture test before pricing?
In short: Yes, and moisture migrating upward through concrete is a leading cause of coating delamination. Two ASTM methods govern the testing, and the results change both the specification and the price. [6]
ASTM F2170 measures internal relative humidity using in situ probes drilled to 40% of slab depth where the slab dries from one side. ASTM F1869 measures surface moisture vapour emission using anhydrous calcium chloride over a 60 to 72 hour period. The two measure different quantities and are not interchangeable. [6]
ASTM F710 references 75% internal relative humidity and 3 lb per 1,000 square feet per 24 hours as thresholds, unless the product manufacturer specifies otherwise. Resinous coating manufacturers frequently publish their own limits, so the governing number is whatever appears on the technical data sheet for the specified system. [6]
Where readings come back high, a moisture vapour barrier primer gets added to the specification. That adds cost. It also prevents the entire floor lifting off the slab in year two, which is not a line item to economize on, particularly in below grade space and older industrial buildings across Hamilton, Toronto, and the Ottawa valley.
What does the floor cost per year over its service life?
In short: Annualized cost per square foot is the figure that matters for a commercial property, and it includes maintenance. A $6.50 system lasting ten years costs $0.65 per square foot per year, while a $4.00 system replaced every three years costs more than double that.
Add the downtime on each replacement cycle and the gap widens further. Standard epoxy needs 48 to 72 hours before full return to service, and in a working plant that shutdown can exceed the cost of the flooring itself.
Maintenance sits inside the same calculation and gets ignored almost universally. The variables are unglamorous:
- Entry matting at every exterior door, which extends coating life more than any other single measure, because tracked in grit is what abrades a floor rather than the traffic itself.
- Daily sweeping or dust mopping in traffic lanes.
- pH neutral cleaners only, since strongly alkaline degreasers and acidic products both degrade epoxy over repeated use.
- Soft pads on auto scrubbers, never stripping pads. Epoxy is not a sacrificial coating, so a scratch stays until the floor is recoated.
None of that happens reliably unless it sits in a written scope of work, which in practice means the janitorial contract rather than production staff at end of shift. Impact Cleaning Services is one example of a provider running industrial and warehouse cleaning programs across Hamilton and the surrounding industrial zones, and the kind of contractor already carrying epoxy appropriate products and pads.
Whoever you use, get the neutral cleaner requirement and the pad specification into the document rather than the conversation. Cleaning crews turn over, and the floor does not care that the previous crew knew better. For facility managers still shortlisting, a recent roundup of Ontario commercial cleaning providers covers what to check on coverage, screening, and certification before signing anything.
Budget a topcoat refresh every five to eight years in a busy industrial setting. Catching a floor before it wears through to bare concrete turns a scuff sand and recoat into a fraction of a full teardown.
How do you read a suspiciously low quote?
In short: Four checks account for nearly every unexplained gap between two bids on the same floor: preparation specification, moisture testing, topcoat, and film build.
- Does the quote name both the preparation method and the target concrete surface profile? Naming one without the other leaves the most expensive variable undefined.
- Is a moisture test included? If nobody mentions ASTM F2170 or F1869, nobody is running one.
- Is there a topcoat? Omitting the urethane or polyaspartic wear layer is the most common way to cut a bid, and the most reliable way to produce a floor that fails inside three years.
- What is the film build in mils? Ten to fifteen mils is light duty. Heavy forklift traffic requires substantially more.
Ask both contractors for those four answers in writing. The price difference usually explains itself.
Definitions
In short: Eight terms that appear in most commercial flooring quotes and decide what you are actually buying.
- 100% solids epoxy. A formulation containing no solvent or water carrier, so applied film thickness equals cured film thickness.
- Concrete surface profile (CSP). A roughness rating from CSP 1 to CSP 10 defined by ICRI Guideline 310.2R-2013, used to specify how aggressively concrete is prepared before coating.
- Film build (mils). Cured coating thickness in thousandths of an inch. Light duty systems run 10 to 15 mils.
- MVER. Moisture vapour emission rate, measured under ASTM F1869 in pounds of water per 1,000 square feet per 24 hours.
- Moisture vapour barrier primer. A primer applied to slabs with high moisture readings to stop vapour pressure lifting the coating.
- Polyaspartic. A fast curing chemistry that returns a floor to service in roughly 24 hours and resists UV yellowing, at higher material cost than epoxy.
- Topcoat. The final wear layer, usually urethane or polyaspartic, carrying abrasion and chemical resistance. Omitting it is the most common way to underprice a bid.
- Urethane cement. A thick, cement modified resin system used where thermal shock, wash down, or freezer temperatures would destroy epoxy.
Frequently asked questions
In short: The six questions that come up most often on Ontario commercial and industrial flooring quotes.
How much does epoxy flooring cost per square foot in Ontario?
Installed epoxy flooring in Ontario runs $4 to $12 per square foot in 2026. Most residential garage and basement projects land between $5 and $10. Commercial and industrial grade systems, which use higher solids content and thicker film builds, typically run $8 to $15 per square foot. Concrete condition and project size move the figure within those bands.
Why are two epoxy quotes for the same floor so far apart?
Preparation specification and film thickness explain most gaps. One contractor may price grinding to a stated surface profile while another prices a lighter method with no profile named. Film build can differ by a factor of three between bids described identically as high build epoxy. Ask both for the method, the target CSP, the moisture test result, and the total mil thickness.
How long does a commercial epoxy floor last?
A 100% solids epoxy system installed over properly prepared concrete typically delivers 8 to 12 years of service. Water based coatings last 3 to 5 years. Urethane cement, used in food processing and wash down environments, is rated for 15 years or more. Forklift traffic volume, chemical exposure, and thermal cycling all shorten these figures.
Does epoxy flooring need a moisture test before installation?
Yes. Moisture migrating upward through a slab is a leading cause of coating delamination. ASTM F2170 measures internal relative humidity using in situ probes, and ASTM F1869 measures surface moisture vapour emission using anhydrous calcium chloride. A quote that does not include a moisture test is pricing a floor without knowing whether the slab can hold one.
Is epoxy or urethane cement better value for a warehouse?
It depends on the environment rather than the price. Epoxy costs less upfront and performs well in dry warehousing with forklift traffic. Urethane cement costs more per square foot but tolerates thermal shock from hot water and steam cleaning, where epoxy fails quickly. In a food processing plant with wash down cycles, the more expensive system is usually the cheaper one over ten years.
How much does surface preparation add to the cost?
Baseline profiling is included in any credible quote. Beyond that, minor preparation on sound newer slabs adds roughly $1 to $2 per square foot. Crack repair, spall patching, and joint treatment price separately. Removing a failed existing coating adds substantial labour, and full resurfacing of badly damaged concrete runs $3 to $7 per square foot on its own.
