Last week someone in Brossard called to tell me their garage was ready for epoxy — they'd cleared out the boxes, moved the chest freezer, and cleaned up a few oil spots with degreaser. They wanted to know what they'd missed. Not much, as it turned out. Garage epoxy in Brossard is a two-day job, with a car parked on the street, and the result holds for 15 to 20 years if it's done right. Here's what it actually involves, from the first visit to handing the space back.

Why Spring Is the Right Window for Brossard
There's a seasonal logic to all of this. Epoxy applies under controlled temperature conditions — most professional systems require a minimum slab temperature of 10°C. An unheated Brossard garage in January can easily sit between -5°C and 5°C. Applying epoxy in those conditions means compromising adhesion before you've even started.
Spring is different. Temperatures stabilize, the freeze-thaw cycles that beat up the concrete all winter are done, and you can clearly see the damage that's accumulated — new cracks, zones starting to crumble at expansion joints. It's also when capillary moisture in the slab is most detectable, because the water table is high after snowmelt.
For garages in older Brossard sectors — San Marina, avenue Leduc, homes from the 1980s and 90s — spring lets you assess the real condition of the concrete after one more winter. These slabs are 30 to 45 years old. That's not necessarily a problem for epoxy, but it's a variable worth checking in person before choosing a system.
Summer works too, as long as the heat doesn't accelerate curing too aggressively. Serious contractors adapt — they start early in the morning during heat waves to keep control over the drying.
Our article on [epoxy and the Quebec climate](/blog/epoxy-climat-quebec) goes into detail on why our winter conditions change the rules for concrete coatings in garages.
What Happens During the Two Days of Installation
Day 1: preparation. This is the loudest and dustiest day. The contractor runs a scarifier or diamond grinding disc across the entire concrete surface to mechanically abrade it. This produces noise and dust for two to three hours — it's non-negotiable. Without this anchor profile, the epoxy doesn't bond to the concrete properly over the long term. Cracks are then filled with resin. If the slab shows capillary moisture detected by a polyethylene test, a vapor barrier primer is applied at this stage. The base coat goes on at the end of the day.
Day 2: application of the finish system. The main coat is applied over the cured base. If you chose a flake system, flakes are broadcast into the wet epoxy immediately after application. After partial curing, the topcoat is applied over everything. The surface is ready for foot traffic 24 hours after the last coat, and for vehicles 72 hours after.
What clients sometimes forget: during those two days, their car is outside. For a double garage, that's two vehicles to park elsewhere for roughly three days. Not a major obstacle — just logistics to plan ahead. It's worth confirming the exact timelines with your contractor before starting.
The [Régie du bâtiment du Québec](https://www.rbq.gouv.qc.ca) notes that any contractor performing work on a residential concrete slab must hold a valid RBQ licence — verify this for free on their site before signing anything.
Our article on [why concrete preparation is critical](/blog/pourquoi-preparer-beton-avant-epoxy) goes through what happens during the scarification day and why this step determines the floor's lifespan.

Oil Stains in Your Garage: Not a Problem, But Mention Them
Almost every residential garage in Brossard has oil or antifreeze stains on the concrete. That's normal — concrete is porous and absorbs everything that falls on it. These stains don't make epoxy impossible, but they need to be handled properly before application.
The standard approach: an industrial degreaser applied and scrubbed mechanically, followed by rinsing and complete drying. For old, deeply embedded stains, a grind pass is sometimes needed to remove the contaminated concrete layer. If this step is skipped or done poorly, epoxy won't adhere properly in those areas — and those exact spots will be the first to peel, often after the first winter.
Mention the stains to your contractor during the initial assessment. Not because it'll change the price drastically, but because it lets them plan the preparation day properly without surprises.
Flakes, Solid, or Metallic: Choosing the Finish for a Brossard Garage
This is often the question that takes up the most mental space before the visit, and it gets resolved in five minutes once you've seen photos of real projects.
For a standard residential garage, decorative flake epoxy is the most common choice, and for good practical reasons. Flakes hide minor concrete imperfections and the micro-scratches that accumulate with daily use. They add a slight texture that improves traction on wet surfaces. And visually, they hold up better to dust and splashes between cleanings than a solid-colour floor.
Solid colour epoxy (no flakes) has a cleaner, more industrial look. For garages that double as workshops, it's often a good fit: the smooth surface is slightly easier to deep-clean.
Metallic epoxy, with its depth effects and pearlescent tones, is visually impressive. But it costs significantly more, requires an experienced applicator, and in a garage where you park an SUV and store winter tires, the budget justifies itself less than in a basement or showroom. Not a bad idea — just rarely the best use of resources for a standard garage.

| Finish | Relative price | Maintenance | Wet traction | Best for |
|---|---|---|---|---|
| Epoxy with flakes | $$ | Easy | Good | Standard residential garage |
| Solid colour epoxy | $ | Very easy | Adequate | Workshop, clean aesthetic |
| Metallic epoxy | $$$ | Moderate | Adequate | Showroom, luxury garage |
| Polyaspartic | $$–$$$ | Easy | Very good | Sun-exposed garage |

How Long It Lasts, and What Shortens That
A properly installed epoxy floor in a Brossard garage — with serious mechanical scarification, appropriate primer if the slab needs it, and a professional system — lasts 15 to 20 years. I have clients with floors installed in the late 2000s that are still in perfect shape. I've also seen others start deteriorating after five years. The difference almost always comes down to two things: quality of concrete preparation, and a few basic maintenance habits.
What concretely shortens a garage epoxy floor's lifespan:
- De-icing salt used in excess. A bit of calcium in winter is normal. A full bucket directly on the threshold several times a week is aggressive. The [National Research Council Canada](https://nrc.canada.ca/en/research-development/research-collaboration/programs/construction-sustainable-building-research) documents the effects of de-icing agents on concrete coatings in Canadian residential construction.
- Oil or antifreeze stains left too long. Epoxy blocks them, but a greasy film can work into the micro-irregularities of the topcoat if you wait weeks before cleaning. A wipe-down within 48 hours prevents the problem.
- Skipping basic abrasive maintenance. The gravel that tires track in from the street gradually scratches the finish. A broom once a week removes it before it causes visible damage.

Can epoxy be applied in winter in an unheated Brossard garage?
No. Most professional systems require a minimum slab temperature of 10°C. Below that, adhesion is compromised. You can work in winter in a garage heated to at least that temperature, with product-specific precautions.
Do you need to completely empty the garage before epoxy installation?
Yes — the entire floor must be accessible for scarification and application. This includes vehicles, shelving whose legs touch the floor, and anything sitting directly on the concrete. Wall-mounted furniture with no floor contact doesn't need to move.
Is a garage epoxy floor suitable for a workshop with heavy tools?
Yes. For heavy tool use or frequent dropped equipment, quartz epoxy offers superior abrasion resistance over flake systems. For standard residential use, the flake system works very well.
Will existing oil stains show through the epoxy?
No, as long as they were properly treated before application. Mechanical degreasing followed by a grinding pass on heavily contaminated zones eliminates the problem at the source. Untreated areas can create delamination points over time.
How much does a garage epoxy floor cost in Brossard in 2026?
For a single garage (about 200 sq ft), expect $800 to $1,600. For a double (400-500 sq ft), $1,600 to $3,500. Heavily damaged or moist concrete can increase preparation costs by 20 to 30%. A full polyaspartic system costs 20 to 40% more than standard epoxy.
Is there a warranty on a professionally installed epoxy floor?
Serious contractors offer a labour warranty, typically 1 to 5 years depending on the contract. Finish products often carry a separate manufacturer's warranty. Ask for details in writing in your quote — what's covered, what voids it, and the procedure in case of a problem.
