10 Questions Toronto Homeowners Ask Before Getting Epoxy Floors (Answered)

The most common project — a 2-car garage around 400–500 sq ft — runs $2,500–$4,500 all-in with a professional contractor, including surface prep and a full flake broadcast system with polyaspartic topcoat.

The numbers by system type:

• Standard flake broadcast: $3–$5.50/sq ft
• Solid colour epoxy + clear topcoat: $3–$5/sq ft
• Polyaspartic single-day system: $5–$8/sq ft
• Metallic epoxy (3D effect): $8–$14/sq ft
• Basement with moisture primer: $6–$10/sq ft

The price gap between contractors often comes down to prep. A $1,800 quote typically means a light acid etch. A $3,500 quote typically means diamond grinding. These produce very different results 5 years later.

A standard 2-coat epoxy system on a garage takes 2 days:

• Day 1: Diamond grinding, crack repair, primer coat — floor is off limits overnight
• Day 2: Base coat application, flake broadcast, topcoat — floor cures overnight
• Day 3: Light foot traffic OK
• 48–72 hours: Vehicle traffic (park a car)
• 7 days: Full chemical cure

Polyaspartic systems can cut this to one day — morning grind, afternoon coating, drive on it the next morning. More expensive, but back in service faster. Good option if you can't leave the garage empty for a full weekend.

Hot tire pickup is real — and it's the most common failure mode homeowners see when they buy cheap epoxy or hire a contractor who uses inadequate products.

What causes it: your car tires heat up significantly during highway driving. When you pull into a cool garage and park, the hot rubber softens certain epoxy formulations at the contact patch. Over time, the coating delaminates in the shape of your tire prints.

How to avoid it: Specify a 100% solids, two-component epoxy base coat at 10+ mils dry film thickness, with a polyaspartic or aliphatic polyurethane topcoat rated for hot tire exposure. This is the standard spec for every ProEpoxy Toronto garage installation. Do not accept a thin water-based epoxy or a single-part coating.

Yes — with proper prep. Most Toronto garage floors have hairline to moderate cracking from settlement and freeze-thaw cycles. These are not disqualifying.

The process:

• Cracks narrower than 1 mm: can be bridged with a thick epoxy primer
• Cracks 1–3 mm wide: routed (chased wider with an angle grinder) and filled with polyurea crack filler before coating
• Cracks wider than 3 mm or with vertical displacement: structural assessment recommended; can still coat after repair
• Spalls and divots: patched with polymer-modified mortar or epoxy repair mortar

Epoxy does not structurally repair concrete — it coats it. Cracks that continue to move (thermal expansion cracks) will eventually reflect through the coating. These are managed, not eliminated.

Yes, the entire floor must be completely empty and accessible. This includes:

• Both cars out (moved to the street or driveway) for the full duration
• Storage items removed — shelving units that are freestanding, bins, boxes
• Wall-mounted shelving and cabinets can stay (we work around them)
• Fridges, freezers, and hot water heaters bolted down: we'll mask and work around them

If there are floor drains, we'll protect them during application and open them after cure. Workbenches bolted to the wall don't need to move — we coat to within an inch and use a brush cut-in along the perimeter.

Great question — this trips up a lot of homeowners because both terms get used loosely.

• Epoxy is the base coat chemistry. It's the workhorse layer that bonds to the concrete and creates the thick, durable foundation. Slow cure time (6–12 hours), excellent adhesion and hardness.
• Polyaspartic is a topcoat chemistry (technically a type of polyurea). It cures much faster (2–4 hours), is highly UV-stable (won't yellow in sunlight), and has better abrasion and chemical resistance than standard epoxy clearcoats.

A proper system uses both: epoxy base coat(s) for thickness and bond, polyaspartic topcoat for UV stability, abrasion resistance, and fast return-to-service. "Polyaspartic floor" and "epoxy floor" are often used interchangeably by contractors — ask specifically what the base coat chemistry is.

Aromatic epoxy (the most common base coat chemistry) will amber or yellow when exposed to direct sunlight. In a garage with south-facing windows or a frequently-open door where afternoon sun hits the floor, this is visible within 1–2 years.

The solution: a polyaspartic or aliphatic polyurethane topcoat. These UV-stable topcoats block the UV from reaching the epoxy base below. Colour remains stable for 10+ years.

If your garage gets significant sun exposure, make sure you ask specifically about an aliphatic (UV-stable) topcoat — not just any clear topcoat. Some contractors use a cycloaliphatic epoxy clear which is partially UV-stable but still ambers faster than a true polyaspartic.

A smooth epoxy or polyaspartic topcoat is slippery when wet — approximately as slippery as polished tile. In a Toronto garage during winter, tracked-in snow and ice melt creates genuinely hazardous conditions on an unseeded floor.

The fix is built into the installation: we broadcast aluminium oxide or silicon carbide anti-slip aggregate into the topcoat before it cures. This creates a textured surface that provides adequate grip even in wet winter conditions, without significantly affecting the floor's appearance.

Anti-slip broadcast is standard on all ProEpoxy Toronto garage installations. If a contractor doesn't include it by default and doesn't ask about it, that's a red flag.

Yes, with proper preparation. Epoxy requires:

• Concrete surface temperature above 10°C (50°F)
• Air and surface temperature at least 5°C above the dew point (to prevent condensation on the slab)
• No ice or frost on the surface

In Toronto winters, unheated garages fall well below these thresholds from November through March. The solution is temporary heat: we use propane or electric heating units to raise the space to acceptable temperatures 24 hours before prep begins and maintain that temperature through cure.

Polyaspartic topcoats are the preferred topcoat for winter installs — they have a more forgiving cold-temperature cure profile and reach walkable hardness faster than standard epoxy in cold conditions.

Winter installs add modest cost ($200–$400 for heating) but are routinely done by experienced contractors across the GTA.

The contractor matters more than the colour you pick. Here's what to look for:

• They diamond grind — not acid etch. Ask specifically. If they use acid, walk away.
• They moisture-test basements — mandatory on any below-grade floor.
• They use 100% solids, two-component epoxy — not water-based or single-part products.
• They have before/after photos from actual Toronto jobs — not stock imagery.
• They provide a written warranty — at minimum 2–3 years on material and workmanship.
• They don't subcontract — the crew that quotes you should be the crew that shows up.

Be sceptical of extremely low quotes (under $2,000 for a 2-car garage). At that price, someone is cutting corners on prep, product, or both — and you'll be resurfacing in 3 years.
