A properly installed epoxy or polyaspartic garage floor in Calgary holds up to road salt, freeze-thaw cycles and hot-tire pickup — but only when the concrete is diamond-ground, moisture-tested and coated in the right conditions. Polyaspartic coatings cure faster and tolerate colder installs, which matters in Calgary's shoulder seasons. Jonathan Edwards is involved on every job, so you get one point of contact and a fixed-price quote with no surprises.
Why Your Garage Floor Needs Coating
Calgary garage floors take a beating: road salt, chinook freeze/thaw, winter slush, oil drips, tire impact. Bare concrete stains, cracks, and dusts constantly. A good epoxy or polyaspartic coating turns your garage into a finished, easy-clean space.
Epoxy vs Polyaspartic: What’s the Difference?
| Feature | Epoxy | Polyaspartic |
|---|---|---|
| Cost installed | $5-$8/sq ft | $7-$12/sq ft |
| Cure time | 24-72 hrs | 4-24 hrs |
| UV resistance | Moderate (can yellow) | Excellent |
| Temperature range (install) | 10-35°C | −30°C to 50°C |
| Lifespan | 8-15 years | 15-25 years |
| Flexibility | Rigid | More flexible |

Calgary verdict: Polyaspartic wins for cold-climate garages. It can be installed in winter, cures fast, and handles freeze/thaw better.
Cost for a Typical Calgary Garage
| Garage Size | Epoxy | Polyaspartic |
|---|---|---|
| Single (240 sq ft) | $1,200 – $1,900 | $1,700 – $2,900 |
| Double (440 sq ft) | $2,200 – $3,500 | $3,100 – $5,300 |
| Triple (660 sq ft) | $3,300 – $5,300 | $4,600 – $7,900 |
| Shop/XL (900+ sq ft) | $4,500 – $7,200 | $6,300 – $10,800 |

The Install Process
- Prep (80% of the work): Diamond grind or shot blast the concrete to create profile
- Crack & spall repair: Fill any damaged areas with epoxy filler
- Primer coat: Base coat that bonds to concrete
- Basecoat + chips: Coloured layer with decorative flakes broadcast over wet base
- Topcoat: Clear UV-resistant finish (polyaspartic)
Why Surface Prep Matters
90% of failed garage floor coatings failed because of bad prep. The concrete must be ground (not just etched with acid) to open the pores. Calgary garages with sealed concrete absolutely need mechanical grinding. Ask your contractor what prep method they use.
Colour & Flake Options
- Greys: Light, medium, charcoal — most popular
- Earth tones: Tan, coffee, bronze
- Flake size: 1/4″ standard, 1/8″ for clean look, 1″ for loud
- Flake coverage: Full broadcast (recommended) or partial
- Metallic epoxy: Premium swirled look, $10-$18/sq ft
DIY Kits vs Professional Install
DIY kit ($200-$500): Thin epoxy rolled like paint. Lasts 2-5 years. Peels if prep is poor.
Pro install ($2,000-$5,000): Thick, multi-coat system with proper grinding. Lasts 15+ years.
If you’re keeping the house, go pro. If you’re selling soon, DIY might be enough.
Maintenance
- Sweep regularly, mop with mild soap
- Avoid: muriatic acid, bleach, harsh chemicals
- Use mats under tires to protect from hot tire pickup
- Inspect annually for chips or delamination
Calgary-Specific Considerations
- Choose polyaspartic for winter installs
- Pick a contractor experienced with chinook freeze/thaw cycles
- Address moisture vapor transmission (older garages have no vapour barrier under slab)
- Slope check — water must drain to the front

Frequently asked questions
It depends on the size of your garage, the condition of the existing slab, and whether you choose epoxy or a premium polyaspartic system. Your fixed-price quote will vary based on your selections and square footage.
A properly prepped coating can last many years even with our salt and freeze-thaw conditions, and polyaspartic top coats add extra durability and UV resistance. The real determinant of lifespan is surface preparation, not just the product.
Polyaspartic cures faster, resists yellowing and handles colder installs, while epoxy is a proven, cost-effective base — many of the best floors combine an epoxy base with a polyaspartic top coat. We can source a budget system or a premium build; it comes down to what you value.
It can, but temperature and moisture have to be controlled — polyaspartic tolerates cooler conditions better than standard epoxy. We assess the slab and conditions before committing to a timeline so the coating cures properly.
