Epoxy Concrete Floor Coating in Plymouth: The Answer
For a Detroit-metro garage, a polyurea-polyaspartic system holds up better than epoxy over the long run — it flexes with a Michigan slab through every freeze-thaw cycle instead of cracking or losing its bond, and it cures fast enough to use the garage the next day. Epoxy costs less upfront, but on one Plymouth job, an old epoxy coating had actually hidden a wide crack at the garage door threshold for years before it surfaced during removal — epoxy can mask a problem as easily as it can develop one. The trade-off is real: epoxy is cheaper on day one, polyurea-polyaspartic is the system built to survive what’s underneath it.
What We Actually Found in Plymouth
Two Plymouth projects MotorCity has documented show what an old epoxy coating can hide, and what it takes to remove one properly.
Plymouth Ridge Drive — 679 Sq Ft, Two Bays, 11 Steps, and a Failing Epoxy System
At Plymouth Ridge Drive, a 679-square-foot garage floor split across two bays had a prior epoxy system that was failing — delaminating in areas and no longer bonded consistently to the concrete beneath. That coating had to come off before any preparation could begin. Once it was stripped, the concrete underneath told its own story: oil had worked its way into the slab in multiple zones across both bays, tire marks ran through the main parking areas, a crack cut diagonally across one panel, and pitting was distributed across the full surface. The scope also included 29 linear feet of vertical surfaces along the perimeter and 11 interior steps connecting the garage to the house. Our crew diamond-ground the full 679 square feet to clear the contamination and the residual epoxy bond coat, then worked mender compound into the crack and every pitted zone, troweling each flush with the surrounding surface. All 11 steps were hand-abraded — tread, riser, and face — to create a bondable profile. The crew applied an MC-3.8 polyurea-polyaspartic system with Glacier flake — a cool blend of blue-grey, charcoal, and silver — across both bays, the vertical perimeter, and every step, finished with a clear topcoat and 24-grit traction additive.
River Bend Drive — 385 Sq Ft, an Epoxy Coating That Was Hiding a Crack
At River Bend Drive, a 385-square-foot garage floor already carried a solid blue-grey epoxy coating that had run its course — scuffed, scratched, dulled across large zones, and no longer bonded in others. What the coating was actually covering stayed unknown until our crew began grinding. Near the garage door threshold, the grind exposed a wide crack running along the control joint — irregular and wider than a normal control joint, opened by movement at the threshold over time, and invisible from the surface because the old epoxy had simply bridged over it. Our crew diamond-ground the full 385 square feet to strip the epoxy, then worked mender compound along the full length of the crack, allowed it to cure, and ground it back flush with the surrounding concrete. The homeowner selected Driftwood — a warm blend of tan, cream, brown, and grey — applied in a full polyurea-polyaspartic system with a 24-grit traction topcoat. The crack the old epoxy had been hiding is gone entirely beneath the repair and the new coating.
Both projects share the same lesson: an epoxy coating doesn’t just fail on its own — it can actively conceal a problem underneath it, a delaminating bond at Plymouth Ridge Drive, a structural crack at River Bend Drive. Among the Plymouth projects MotorCity has documented, both required a full removal of the original epoxy before the real condition of the slab, and the right fix, was visible at all.
Epoxy or Polyurea-Polyaspartic, Side by Side
| Epoxy | Polyurea-Polyaspartic | |
|---|---|---|
| Upfront cost, installed | $4.50–$8.50/sq ft ($2,000–$3,500, 2-car garage) | $6–$12/sq ft ($2,800–$5,000, 2-car garage) |
| Cure / return-to-service time | Typically several days, longer in cold weather | Often next-day |
| Flexibility under slab movement | Rigid — can crack or telegraph existing cracks | Flexible — moves with the slab |
| UV stability | Prone to yellowing and ambering with sun exposure | Formulated to resist UV yellowing |
| Bond to properly prepped concrete | Depends heavily on prep quality | More forgiving of minor prep variance |
| Resistance to road salt | Can lose adhesion under repeated salt exposure | Built for Michigan freeze-thaw and salt exposure |
| Expected service life (SE Michigan) | 7–15 years professional; 1–3 years DIY kit | 15–20 years |
| Who can install it | Widely available, including DIY kits | Requires a trained crew — no DIY route |

Cost
A firm price before we’ve inspected your slab would be misleading. What decides the number is the condition of what’s already on the concrete, not just the square footage. Our Plymouth Ridge Drive job needed a failing epoxy system stripped from 679 square feet across two bays, crack and pitting repair, plus 29 linear feet of verticals and 11 steps. Our River Bend Drive job needed a smaller epoxy removal, but the crack it uncovered at the threshold needed real repair before anything else could happen.
What Moves the Price on a Plymouth Garage
- Removing a prior coating — both Plymouth Ridge Drive’s failing epoxy and River Bend Drive’s dulled, delaminating epoxy had to come off before anything new could go down.
- Hidden damage revealed during removal — River Bend Drive’s threshold crack wasn’t visible until the old epoxy was ground away.
- Steps, verticals, and multi-bay scope — Plymouth Ridge Drive’s 11 steps and 29 linear feet of vertical surfaces added labor beyond a standard floor.
| Item | Range |
|---|---|
| Professional epoxy, installed | $4.50–$8.50 per sq ft |
| Professional epoxy, typical 2-car garage | $2,000–$3,500 |
| Polyurea/polyaspartic, installed | $6–$12 per sq ft |
| Polyurea/polyaspartic, typical 2-car garage | $2,800–$5,000 |
| Difference between the two on the same garage | roughly $1,000–$1,500 |
| DIY epoxy kit, 2-car garage | $150–$650 |
| Removing a failed coating | $2–$4 per sq ft (roughly $800–$1,800 on a 2-car garage) |
| Service life, professional epoxy (SE Michigan) | 7–15 years |
| Service life, polyurea/polyaspartic (SE Michigan) | 15–20 years |
| Service life, DIY water-based kit | 1–3 years |
A “typical 2-car garage” runs 400–500 square feet — close to River Bend Drive’s actual size, while Plymouth Ridge Drive’s two-bay layout ran larger. Epoxy is cheaper on day one, but both Plymouth projects are the counter-example in MotorCity’s own records: a first epoxy installation that failed or hid damage, and a second installation that had to absorb the cost of finding out. Day-one savings and lifetime cost are not the same comparison.
Michigan Conditions
A Plymouth garage floor goes through the same freeze-thaw cycling, road salt, and daily vehicle traffic as anywhere else in the Detroit metro, and Plymouth’s housing stock ranges from historic homes near the city center to newer construction on the surrounding streets — so the concrete our crews find, and what’s sometimes hiding under a prior coating, varies from job to job. Epoxy can perform well when it’s installed correctly, but it demands precise surface preparation and has little margin for error: skip the diamond grinding, coat over a crack instead of repairing it, or let a delaminating bond go unaddressed, and the coating eventually lets go — or worse, hides a problem that gets more expensive the longer it sits. That’s exactly what happened at River Bend Drive, where a wide crack sat undetected under a coating for years before our crew’s grinding revealed it.
FAQ
A 20×20 garage is 400 square feet, close to the size of our River Bend Drive project (385 sq ft) in Plymouth. Professional epoxy runs $4.50–$8.50 per square foot installed, or roughly $2,000–$3,500 total. On the River Bend Drive project, the garage needed a dulled, delaminating epoxy coating fully stripped — a step that also revealed a hidden crack requiring repair, which adds real cost beyond the base square-footage rate.
Prices in the Detroit metro area tend to vary from $2,000–$3,500 for a professional epoxy installation on a typical two-car garage of 400–500 square feet, and from $2,800–$5,000 for a polyurea-polyaspartic system. Those are regional ranges and do not change from one city to the next. Actual quotes are provided after a visual inspection of the concrete to be coated, because the process changes with the state of the slab. Among the Plymouth garages MotorCity has documented, one covered 679 square feet across two bays with a delaminating epoxy to remove, oil and crack repair, 29 linear feet of verticals and 11 steps. Another, at 385 square feet, was a worn epoxy that turned out to be hiding a crack at the garage door threshold. Same city, different work, different numbers.
Yes — epoxy can bridge over a crack or void instead of exposing it, which is exactly what MotorCity’s crew found at River Bend Drive in Plymouth: a wide crack at the garage door threshold sat completely hidden under a blue-grey epoxy coating until diamond grinding removed the old material and exposed it. A coating that looks intact on the surface can still be masking a problem underneath, which is one more reason a full removal and inspection matters more than coating over what’s already there.
For an unheated Detroit-metro garage, a polyurea-polyaspartic system rates highest for durability — 15–20 years in SE Michigan conditions versus 7–15 years for professional epoxy. It’s also more forgiving during installation: at MotorCity’s Plymouth Ridge Drive project, the crew coated two full bays, 29 linear feet of verticals, and 11 steps as one continuous, properly bonded system. The trade-off is cost: polyaspartic runs $6–$12 per square foot installed against $4.50–$8.50 for epoxy, and it requires a trained crew rather than a DIY kit.
