With polyurea coating
72 hrs
Full Chemical Cure
Maximum resistance
A standard garage floor coating installation takes two days from start to finish. Day one is preparation — grinding the concrete, repairing cracks, and creating the surface profile that makes the coating bond permanently. Day two is application — the base coat, color flake broadcast, and clear topcoat go down in sequence.
With Penntek polyurea, you can walk on the floor within hours and park your car the next day. That's the practical difference between polyurea and epoxy — epoxy installations look similar but require 3–7 days before you can park, and up to 30 days for full cure.
Here's exactly what happens at each stage, so you know what to expect and can plan around your schedule.
Before Installation Day
The work starts before our crew arrives. Here's what happens during the planning phase and what you need to do to prepare.
Step 1: Free Design Consultation (30–45 minutes)
We visit your garage, measure the space, assess the concrete condition, and discuss your goals. This is where we identify any cracks, moisture issues, or structural concerns that could affect the installation. You'll choose your color and flake pattern from physical samples — not a screen. We'll provide a detailed quote before we leave.
Step 2: Scheduling (1–3 weeks out)
Once you approve the quote, we schedule your installation. During peak season (spring and summer in Minnesota), lead times are typically 2–3 weeks. Fall and winter installations can often be scheduled within 1–2 weeks. We'll confirm your dates and send a preparation checklist.
Step 3: Your Preparation (the day before)
Clear everything from the garage floor — tools, storage, vehicles, shelving, everything. The floor needs to be completely accessible. Most homeowners move items to the driveway, a spare room, or rent a temporary storage pod. If you have wall-mounted items that don't touch the floor, those can stay. Plan to park in the driveway for 2–3 days.
Day 1: Preparation
⏱ Typical duration: 6–8 hours · Crew arrives between 7:00–8:00 AM
Day one is the most labor-intensive part of the process. This is where the quality of your coating is determined — proper preparation is what separates a coating that lasts a lifetime from one that peels in two years. Here's what our crew does, hour by hour.
Morning: Diamond Grinding (2–3 hours)
Our crew uses industrial diamond grinders to remove the top layer of concrete and create a surface profile called CSP-3 (Concrete Surface Profile 3). This profile has the texture of medium-grit sandpaper — rough enough for the coating to mechanically bond to the concrete at a molecular level.
This step also removes any existing paint, sealer, or contamination from the concrete. The grinders are connected to industrial vacuum systems that capture 99% of the dust. Your garage will be dusty, but your house won't be.
Mid-Morning: Crack and Joint Repair (1–2 hours)
After grinding reveals the true condition of the concrete, our crew addresses every crack, chip, pit, and spall. Cracks are chased out (widened slightly) and filled with flexible polyurea crack filler that moves with the concrete through Minnesota's freeze-thaw cycles.
Control joints (the lines cut into the concrete when it was poured) are filled to create a smooth, continuous surface. Pitting and spalling are filled and leveled. This repair work is included in the standard installation cost — it's not an upcharge.
Afternoon: Moisture Testing and Final Prep (1–2 hours)
The crew tests the concrete for moisture using a calcium chloride test or relative humidity probe. Excess moisture is the #1 cause of coating failure — if the concrete is too wet, the coating won't bond properly. If moisture levels are too high, we'll discuss mitigation options before proceeding.
The floor is then vacuumed, blown clean, and inspected one final time. Every square inch needs to be free of dust, debris, and contamination. The crew tapes off walls, door frames, and any surfaces that shouldn't be coated. By late afternoon, the floor is ready for coating the next morning.
What you'll notice on Day 1:
- • The grinding is loud — comparable to a commercial vacuum. It lasts 2–3 hours.
- • There will be some dust despite the vacuum system. Keep garage-to-house doors closed.
- • The crew will need access to a power outlet and water source.
- • Your concrete will look rough and raw at the end of the day — that's exactly right.
Day 2: Coating Application
⏱ Typical duration: 4–6 hours · Crew arrives between 7:00–8:00 AM
Day two is when the transformation happens. The coating goes down in layers, each one serving a specific purpose. Here's the sequence.
Early Morning: Base Coat Application (1–2 hours)
The Penntek polyurea base coat is applied directly to the prepared concrete. This layer penetrates the concrete's pore structure and creates the primary bond. It's applied with professional-grade rollers in a specific pattern to ensure even coverage. The base coat is typically a solid color that matches your chosen flake blend.
Mid-Morning: Flake Broadcast (30–60 minutes)
While the base coat is still wet, the crew broadcasts decorative vinyl flakes across the entire surface. Canvas does a full-broadcast application — meaning the flakes completely cover the base coat for a rich, textured finish. This isn't a light sprinkle. The floor is saturated with flake, then excess is scraped and vacuumed after it cures. The result is a dense, uniform appearance with no visible base coat showing through.
Late Morning: Scrape and Vacuum (1 hour)
After the base coat cures enough to lock the flakes in place, the crew scrapes the surface smooth with floor scrapers. This removes any flakes that didn't bond and creates a flat, even surface for the topcoat. The floor is then vacuumed clean of all loose material.
Afternoon: Clear Topcoat (1–2 hours)
The final layer is a UV-stable polyurea clear coat that seals everything in and provides the chemical resistance, abrasion resistance, and gloss that define the finished floor. This topcoat is what protects against road salt, hot tire pickup, oil, and the daily wear of a working garage.
The crew applies the topcoat in a systematic pattern, working from the back of the garage toward the door. Once the topcoat is down, the garage door stays closed and no one walks on the floor until it cures.
What you'll notice on Day 2:
- • The process is quieter than Day 1 — no grinding.
- • There will be a mild chemical smell during application. It dissipates within hours.
- • The crew finishes by early-to-mid afternoon in most cases.
- • Your floor will look finished when the crew leaves — the transformation is dramatic.
After Installation
The coating is down, but there are a few things to know about the cure period and getting your garage back to normal.
| Milestone | Polyurea | Epoxy |
|---|---|---|
| Light foot traffic | 4–6 hours | 24–48 hours |
| Move items back | 12–24 hours | 48–72 hours |
| Park vehicles | 24 hours | 3–7 days |
| Full chemical cure | 72 hours | 7–30 days |
| Heavy equipment / jack stands | 72 hours | 30+ days |
Care during the first 72 hours: Avoid dragging heavy items across the floor. Use felt pads under anything you set down. Don't spill gasoline, brake fluid, or harsh chemicals on the floor until the full 72-hour cure is complete. After that, the floor is fully resistant to everything a garage throws at it.
Long-term maintenance: Sweep or blow out debris regularly. Mop with warm water and a mild cleaner when needed. That's it. No waxing, no resealing, no annual maintenance. The floor takes care of itself.
What Affects the Timeline
Most installations follow the standard 2-day schedule. But some garages take longer. Here's what can extend the timeline and by how much.
Garage size
A standard 2-car garage (400–500 sq ft) fits the 2-day schedule. A 3-car garage (600–800 sq ft) may push Day 1 preparation to a full 8 hours. Garages over 1,000 sq ft may require a third day.
Concrete condition
Severely cracked, spalled, or previously coated concrete requires additional preparation time. If the existing coating needs to be fully removed, that can add half a day to a full day of grinding.
Moisture issues
If moisture testing reveals high levels, a moisture mitigation primer may be needed. This adds a step between preparation and base coat application, potentially requiring the coating to be applied on Day 3 instead of Day 2.
Temperature extremes
Winter installations in Minnesota may require additional time to bring the garage and concrete to proper temperature. Polyurea is more forgiving than epoxy, but extreme cold can slow cure times slightly.
Additional services
If you're adding cabinets, SlatWall, or wall panels as part of a complete system, those are typically installed after the floor coating cures. Cabinet installation is usually a separate day, scheduled 2–3 days after the floor is complete.
Polyurea vs. Epoxy: The Timeline Difference
The installation process looks similar for both coatings. The difference is in how long each step takes and how quickly you get your garage back. This matters more than most homeowners realize — especially if you only have one garage and need to park inside.
| Phase | Polyurea (Canvas) | Epoxy (typical) |
|---|---|---|
| Preparation | 1 day | 1 day |
| Coating application | 1 day | 1–2 days |
| Cure before parking | 24 hours | 3–7 days |
| Full chemical cure | 72 hours | 7–30 days |
| Total days without garage | 2–3 days | 5–10 days |
| Winter installation? | Yes — wider cure range | Risky — cold slows cure |
In Minnesota, the timeline difference matters more than in warmer climates. When it's January and your garage is your only covered parking, the difference between 2 days without your garage and 10 days is significant. This is one of the practical reasons Canvas uses Penntek polyurea exclusively.
Planning Around Your Life
Most homeowners want to know: when's the best time to do this? Here's how to think about scheduling your installation around Minnesota's seasons and your own calendar.
Spring (March–May)
+ Moderate temperatures, concrete warms naturally, garage cleaning season
− Peak demand — longer lead times (2–3 weeks)
Most popular. Book early.
Summer (June–August)
+ Ideal conditions, fastest cure times, easy to keep garage open
− Highest demand — schedule fills fast
Best conditions. Plan ahead.
Fall (September–November)
+ Demand drops, shorter lead times, still warm enough for ideal curing
− Need to complete before deep freeze
Best value. Great timing.
Winter (December–February)
+ Shortest lead times, garage is least used, polyurea handles cold
− Concrete needs to be warmed, slightly longer cure
Totally doable. We install year-round.
Pro tip: Combine services to save time
If you're planning cabinets, SlatWall, or wall panels in addition to the floor, schedule them together. The floor goes first (2 days), cures for 1–2 days, then cabinets install (1 day). A complete garage transformation — floor, cabinets, and wall organization — can be finished in under a week. That's one week of disruption for a space you'll use every day for decades.
