You’ve done the research. You’ve picked a product, gotten a quote, and booked an installer. Now you’re wondering: what actually happens on the day? How do you prepare? And when can you park in your garage again?
This guide walks you through the full process from start to finish, so there are no surprises and your project goes as smoothly as possible.
Getting Ready: What to Do Before the Installer Arrives
The prep work you do ahead of time makes a real difference in how smoothly the day goes.
Clear the Garage Completely
Everything on the floor needs to come out. That means vehicles, bikes, storage bins, tool cabinets, and any freestanding shelving. Wall-mounted items can usually stay, but anything sitting on the concrete needs to go.
Do this the evening before if you can. It takes longer than you expect, and it lets the concrete breathe overnight so the surface is as dry as possible when the crew arrives.
Check for Moisture
Moisture is one of the biggest causes of coating failure. If your garage has had water seeping in through the floor or walls, let your installer know before they arrive. They may recommend a moisture test or a different product for your situation.
A quick DIY check: tape a piece of plastic wrap flat against the floor and leave it overnight. If moisture collects underneath, flag it with your installer before the job starts.
Do a Walk-Through Before the Work Begins
Before the crew starts grinding, walk them through any existing cracks, oil stains, or soft spots you’ve noticed. These are normal and usually very manageable, but it’s better to flag them early so the team can factor them into their prep time and approach.
What Happens on Installation Day
Here’s a breakdown of what most professional garage floor coating installations look like from start to finish.
Step 1: Surface Preparation
This is the most important part of the job. The crew will grind the concrete using diamond grinders or a shot blaster to open up the surface and give the coating a solid mechanical bond.
Expect it to be loud. Dust is contained with industrial vacuums, but some fine concrete dust is normal. During this phase, the crew will also fill cracks, divots, and low spots so the finished floor looks and performs evenly.
Step 2: Primer Coat (If Applicable)
For epoxy systems, a primer coat goes down first. It soaks into the prepared concrete and creates a strong chemical bond for the base coat above it. Polyaspartic and polyurea jobs often skip a separate primer, since those products penetrate quickly on their own.
Step 3: Base Coat and Decorative Flakes
This is where your chosen colour goes down. If you’re getting a flake or chip finish (by far the most popular option for Canadian garage floors), the decorative flakes are broadcast into the wet base coat immediately after it’s rolled out. The crew works quickly here because timing matters. Once the base coat starts to set, the window for adding flakes closes.
Step 4: Topcoat
The final layer is a clear sealer, typically a polyaspartic, polyurethane, or polyurea product. This coat protects your floor from chemical spills, hot tyre marks, and daily wear and tear. It also determines the sheen level of your finished floor, from a high gloss to a satin finish.
How Long Does the Job Take?
Most residential garage floor coating jobs fall into a predictable range:
A single-car garage can usually be completed in one full day. A two or three-car garage typically takes two days, with the first day covering surface prep and base coats and the second day finishing with the topcoat. Larger jobs, heavily damaged concrete, or multi-room projects take longer and should be discussed with your installer before booking.
When Can You Use Your Garage Again?
This is the question every homeowner asks first. Here’s the general timeline:
Light foot traffic is typically fine after 12 to 24 hours. Parking your vehicle usually requires 48 to 72 hours, depending on the product used. Polyaspartic coatings cure faster than traditional epoxy, and some are vehicle-ready within 24 hours in the right conditions.
Your installer will give you specific guidance based on what was applied. Follow it closely. Parking too soon is one of the most common ways to damage a new floor coating, and it’s entirely preventable.
For the first week after installation, also avoid dragging heavy or sharp objects across the surface, using harsh chemical cleaners, and storing anything that traps moisture directly on the floor.
Frequently Asked Questions
Do I need to be home during the installation?
You don’t need to be there the whole time, but plan to be present for the beginning (walk-through and surface inspection) and the end (final inspection before the crew leaves). If something comes up mid-job, your installer should be able to reach you by phone.
What if the weather is bad on installation day?
Rain outside doesn’t affect work happening inside a garage. High humidity can slow curing times, especially for epoxy systems. Your installer will monitor conditions and let you know if the weather is going to affect the schedule or the curing window.
Can existing cracks be coated over?
Yes, in most cases. Minor cracks and settling lines are filled during surface prep and won’t affect the final result. Structural cracks that are actively widening should be assessed separately before coating. A good installer will flag the difference for you during the walk-through.
What temperature does it need to be in Canada?
Most coatings require a minimum of 10 to 15 degrees Celsius both in the air and at the concrete surface. Spring through fall is the practical installation window across most of Canada. Installers in milder climates like the Lower Mainland of BC sometimes work year-round, but always check with your installer about minimum temperature requirements before booking.
How much smell should I expect?
Traditional epoxy has a noticeable chemical odour during application. Keep the garage well ventilated on the day of installation and for the first 24 hours of curing. Polyaspartic and polyurea products have significantly lower VOCs and are much less pungent. If odour is a concern, ask your installer which product they’re using and what ventilation they recommend.
What if I notice something I’m not happy with after the job?
Do your final walk-through before the installer leaves. It’s far easier to address a concern on the day than after the crew has packed up and driven away. A professional installer will walk the floor with you at the end and address any spots that don’t meet expectations before calling the job complete.
