What an Epoxy Garage Floor Actually Costs in Toronto in 2026
Epoxy garage floor pricing in Toronto ranges from $3/sq ft for a basic 2-coat roll-on system to $14/sq ft for a custom metallic epoxy. The problem is that most homeowners compare quotes without understanding what's included - and the cheapest quote almost always leaves out the most important part: surface preparation.
The number one cause of epoxy failure is inadequate surface prep. A $3/sq ft roll-on epoxy on a non-abraded concrete surface will peel within 2 years. A properly diamond-ground slab with a moisture-tolerant primer will hold a $7/sq ft system for 15+ years. Ask every contractor: "Is diamond grinding included in this price?"
| System | What's Included | Cost / sq ft | 2-car garage total |
|---|---|---|---|
| 2-coat solid epoxy | Primer + base coat, no topcoat | $3–$5 | $1,320–$2,200 |
| Vinyl flake + polyaspartic | Primer + base + flake + poly topcoat | $7–$10 | $3,080–$4,400 |
| Metallic epoxy | Primer + metallic base + clear topcoat | $8–$14 | $3,520–$6,160 |
| Polyaspartic 2-coat | Poly base + poly topcoat (fast cure) | $9–$13 | $3,960–$5,720 |
All ProEpoxy quotes include diamond grinding, crack repair, and the complete coating system. There are no hidden prep upcharges. A 2-car Toronto garage averages 440 sq ft.
What Affects the Final Price
- Garage size: most Toronto attached garages are 400–550 sq ft (2 cars). Larger garages (3-car, tandem) scale linearly.
- Concrete condition: heavy cracking, previous coating removal, or significant spalling adds $0.50–$1.50/sq ft for remediation.
- System type: vinyl flake vs metallic vs solid color - the flake broadcast system is the most popular and provides the best hide for minor surface imperfections.
- Anti-slip aggregate: aluminum oxide grit added to the topcoat for traction. ProEpoxy includes this at no upcharge on all residential garage floors.
- Cove base: a 4" epoxy cove where floor meets wall, standard in some systems, optional add-on in others.
The Full Installation Process: Step by Step
1
Moisture Testing
A calcium chloride or Tramex moisture meter test determines the concrete slab's moisture vapour emission rate (MVER). If above 3 lbs/1000 sq ft/24 hrs, a moisture-tolerant primer is required. Skipping this step is the most common reason for delamination within the first 2 years - especially in Toronto basements and garages with older slabs.
2
Diamond Grinding
The concrete surface is mechanically abraded with a walk-behind or ride-on diamond grinder to a Concrete Surface Profile (CSP) of 2–3. This opens the concrete pores and creates mechanical tooth for the epoxy to bond into. Acid etching is an inferior substitute - it creates an inconsistent profile and leaves residue that interferes with adhesion.
3
Crack and Defect Repair
Cracks are cleaned, inspected for activity, and filled with a semi-rigid polyurea filler (for minor cracks) or epoxy mortar (for structural cracks wider than 3mm). Control joints are either bridged or left open with matching caulk depending on whether they remain active. All repairs are feathered flush to the slab surface before coating.
4
Primer Coat
A low-viscosity epoxy primer penetrates the open concrete pores and forms the adhesion bond for the base coat above. This coat is thin - typically 4–6 mils. In high-moisture applications, a moisture-tolerant (MT) primer is used, which has a different chemistry that remains stable under higher MVER conditions.
5
Base Coat and Flake Broadcast
For vinyl flake systems (the most popular choice), a pigmented epoxy base coat is applied at 12–16 mils. Vinyl flake chips are then broadcast into the wet base coat - a "full broadcast" covers the base coat completely for maximum chip density and a uniform appearance. The broadcast layer is allowed to cure, then scraped and swept before topcoat.
6
Polyaspartic Topcoat
A polyaspartic aliphatic urethane topcoat seals and protects the system. This is the UV-stable, abrasion-resistant outer surface you'll walk and drive on. Applied at 4–8 mils, it cures hard in 4–6 hours (walkable) and 24 hours (vehicle traffic). Unlike standard epoxy topcoats, polyaspartic won't yellow in UV light - critical for Toronto garages with any natural light exposure.
Red Flags in Epoxy Garage Floor Quotes
"Surface prep charged separately" - prep is the most important part of the job. Any professional quote includes diamond grinding. Separating it is a way to lower the headline number.
"We use acid etching, not grinding" - acid etching creates an inconsistent profile, leaves residue, and does not open the concrete adequately for a durable bond. Ground concrete holds epoxy 2–3x longer than acid-etched.
No moisture test mentioned - any contractor not performing a moisture test before specifying a primer is guessing. A wet slab with a standard primer will delaminate.
One-day polyaspartic at $2–$3/sq ft - legitimate single-day polyaspartic systems cost $9–$13/sq ft. A price well below this usually means a thin single-coat product applied without adequate prep - it will peel in 12–18 months.
No written warranty - reputable Toronto epoxy contractors provide a written workmanship warranty of 2–5 years. Verbal assurances are not warranties.
Frequently Asked Questions
How much does an epoxy garage floor cost in Toronto?
A standard 2-car Toronto garage (440–500 sq ft) with vinyl flake + polyaspartic topcoat costs $3,080–$5,000 installed. Per-sq-ft range: $3–$5 for basic 2-coat solid epoxy, $7–$10 for flake + polyaspartic, $8–$14 for metallic epoxy. All ProEpoxy quotes include diamond grinding and crack repair.
How long does installation take?
One day for a standard 2-car garage with a polyaspartic topcoat system. The floor is walkable 4–6 hours after the topcoat is applied, and ready for vehicle traffic in 24 hours. Standard epoxy topcoat systems require 5–7 days for full cure before parking vehicles.
Can epoxy be installed in winter in Toronto?
Yes, with proper preparation. Epoxy requires concrete temperature above 10°C during application. ProEpoxy uses propane heaters to maintain floor temperature for winter jobs. Polyaspartic systems are more cold-tolerant. All winter jobs include a written temperature protocol.
What is the difference between epoxy and polyaspartic?
Epoxy is the base coat bonded to concrete. Polyaspartic is the topcoat applied over epoxy - it adds UV stability, faster cure time, and abrasion resistance. Most professional Toronto systems combine both. A "polyaspartic only" quote with no epoxy base is usually a thin single-coat product that won't last as long.
