Three Fundamentally Different Technologies
Epoxy, polyaspartic, and polished concrete are not interchangeable options on a spectrum of quality. They are fundamentally different approaches to transforming a concrete floor, each with distinct chemistry, performance profiles, and appropriate applications. Choosing the wrong one for your situation costs money twice — once for the failed system and once for the replacement.
Full Comparison Table
| Property | Epoxy | Polyaspartic | Polished Concrete |
|---|---|---|---|
| What it is | Coating applied over concrete | Fast-cure coating over concrete | The concrete itself, mechanically refined |
| UV stability | Poor (yellows) | Excellent (aliphatic) | Excellent (no coating) |
| Min. install temp | +10°C substrate | −30°C | +5°C |
| Install time (500 sq ft) | 2 days | 1 day | 2–3 days |
| Cure time | 24–72 hrs | 1–4 hrs | Same day (densifier cures fast) |
| Cost/sq ft (Toronto) | $7–$14 | $10–$18 | $5–$12 |
| Can peel/delaminate | Yes (if prep fails) | Yes (if prep fails) | No (it's the slab) |
| Colour options | Unlimited | Unlimited | Limited (concrete colour) |
| Slip resistance control | Yes (aggregate) | Yes (aggregate) | Yes (grit level) |
| Maintenance | Low | Low | Very low (no wax needed) |
| Lifespan (Toronto) | 8–15 years | 10–20 years | Indefinite (the slab) |
When to Choose Epoxy
- Colour or decorative finish is required (metallic, chip broadcast)
- Chemical resistance above standard polished concrete is needed (oils, acids)
- Shaded garage or basement with no direct UV exposure
- Budget-sensitive with need for colour customization
- Concrete surface has too many repairs or imperfections to polish acceptably
When to Choose Polyaspartic
- UV-exposed application (garage facing south/west, any skylit space)
- One-day install required — polyaspartic is the only professional 1-day system
- Winter installation in Toronto (below 10°C garage)
- Colour or decorative finish required with UV stability
- Upgrade from existing degraded epoxy topcoat (polyaspartic refresh coat)
When to Choose Polished Concrete
- Large open commercial space (warehouse, retail, office over 1,500 sq ft)
- Long-term ownership — polishing is a one-time treatment with minimal lifetime maintenance cost
- Concrete slab is in excellent condition with consistent aggregate
- Aesthetic preference for industrial/contemporary look
- No need for colour beyond concrete's natural tone
Toronto Cost Comparison
| Application | Epoxy | Polyaspartic | Polished Concrete |
|---|---|---|---|
| Double garage (500 sq ft) | $3,500–$7,000 | $5,000–$9,000 | $3,000–$6,000 |
| Basement (700 sq ft) | $4,900–$9,800 | $7,000–$12,600 | $3,500–$8,400 |
| Warehouse (5,000 sq ft) | $35,000–$55,000 | $50,000–$90,000 | $25,000–$60,000 |
| Office/retail (2,000 sq ft) | $14,000–$28,000 | $20,000–$36,000 | $10,000–$24,000 |
Frequently Asked Questions
What is the difference between epoxy, polyaspartic, and polished concrete in Toronto?
Epoxy is a 2-part coating applied over concrete, providing colour, chemical resistance, and a sealed surface at $7–$14/sq ft. Polyaspartic is a fast-cure, UV-stable coating that outperforms epoxy in Toronto's winters at $10–$18/sq ft. Polished concrete mechanically densifies and grinds the concrete itself to a reflective finish — no coating layer — at $5–$12/sq ft depending on grit level.
Which concrete floor option is cheapest in Toronto?
Polished concrete (salt & pepper, 400 grit, satin sheen) is the lowest-cost professional option at $5–$7/sq ft for large areas. Standard epoxy starts at $7–$9/sq ft. Polyaspartic starts at $10–$12/sq ft. DIY epoxy kits cost $2–$4/sq ft installed but fail within 1–3 years under Toronto conditions.
Which floor coating lasts longest in Toronto?
Polished concrete lasts indefinitely since the floor is the concrete itself — it cannot delaminate or peel. Professional epoxy with polyaspartic topcoat lasts 10–20 years. Standard epoxy without UV-stable topcoat lasts 5–12 years in Toronto's climate.
Can you polish any concrete floor in Toronto?
No. Polished concrete requires minimum 100mm slab thickness, sufficient aggregate exposure potential, and concrete hardness above 3,000 psi. Soft, honeycombed, or thin slabs cannot be polished. Many Toronto basement slabs from pre-1980 construction are too soft or thin for polishing — epoxy is the better choice in these cases.
What is the best concrete floor treatment for a Toronto office or retail space?
For retail and office, polished concrete (800–1500 grit, semi-gloss or gloss sheen) is the premium choice for aesthetics, longevity, and low maintenance at $8–$12/sq ft. Metallic epoxy is an alternative for stronger visual impact at $12–$25/sq ft. Standard epoxy is adequate for back-of-house retail and warehousing at $7–$11/sq ft.
