Upgrading Garage Floor Coating in Grosse Pointe with Polyurea-Polyaspartic Coatings

On this page, we document garage floor coating projects in Grosse Pointe, MI. Our dual-coating systems have converted worn concrete slabs into durable, attractive garage floors. Grosse Pointe is a Wayne County community on the western shore of Lake St. Clair — one of the five Grosse Pointe communities defined by their established residential character, mature tree-lined streets, and well-maintained properties. Garages in Grosse Pointe reflect the age of the housing stock: many are attached to homes built across the mid-twentieth century, with concrete slabs that have absorbed decades of Michigan winters, vehicle fluids, and seasonal freeze-thaw stress.

Many of the properties where we apply our polyurea-polyaspartic floor coating systems had accumulated the wear and tear of the harsh Michigan climate. As you will see in these case studies, our garage floor coating specialists work with concrete slabs in a wide variety of conditions: some needed only standard surface preparation. Others required multi-stage remediation — oil extraction, crack repair, full-slab flood coating, and double grinding passes — before the polyurea and polyaspartic coats could go down. We describe the process and results, and include the before-and-after photos for each job.

Grosse Pointe Garage Floor Coating Case Studies

These case studies carefully document the condition of the concrete slab, the challenges we encountered, and the steps our crew took to prepare and restore the concrete slab before applying the dual-layer system. Each project reflects a variety of conditions to be addressed, and shows the consistent quality standards MotorCity Floors and Coatings applies to every installation.

Quality Garage Floor Coatings

Winter road salt, freeze-thaw cycles, automotive fluids, and daily vehicle traffic degrade unprotected garage concrete over time. The damage typically appears as oil staining, cracking, surface pitting, and efflorescence deposits where moisture has been migrating upward through the slab.

Several of our jobs of garage floor coating in Grosse Pointe involved slabs carrying more than one overlapping condition at the same time. At the Blairmoor Court property, our crew found a prominent X-shaped crack network, broad oil saturation across both parking bays, distributed pitting, and white efflorescence deposits — all on the same 450-square-foot slab. Each condition required its own treatment step before any coating could begin. Polyurea-polyaspartic systems, installed correctly over fully prepared concrete, provide reliable long-term protection against these conditions and deliver a finished appearance that bare concrete or epoxy products cannot match.

The Starting Point

The garage at this Dodge Place property covered 655 square feet divided across two bays. The two bays told different stories. The older parking area showed accumulated wear: oil staining had settled into the concrete in dark, spreading clusters across the main parking zone. A crack ran diagonally across the slab at a control joint intersection. Light pitting was distributed across the surface throughout the older section. The second bay was newer concrete — no oil saturation, no cracking, and minimal surface wear. Both sections would receive the same system. No steps were included in the scope. A 1–2 inch vertical area along the exterior wall under the molding was included.

Surface Preparation

Our crew diamond-ground the full 655 square feet. The grind removed the laitance layer across both bays and opened the surface of the concrete throughout. The oil-stained zones in the older parking area required full passes to clear the contamination and expose clean concrete below. The crack at the control joint was profiled during the grind. The newer bay required the same mechanical profiling — fresh concrete does not accept coating without an open surface profile. Our team vacuumed the full floor before moving to repair.

Crack Repair and Full-Slab Flood Coat

Our crew packed mender compound into the diagonal crack along its full length. The light pitting distributed across the older bay received the same mender treatment. With spot repairs in place, our team applied a full-slab mender flood coat across all 655 square feet. The flood coat encapsulates the repaired areas and brings the entire surface to a consistent, level profile. The photos show the wet compound spread across both bays in broad, overlapping passes — covering the older section and continuing through the newer concrete without interruption.

Grinding the Repairs Flush

Our crew ran the grinder across the full slab a second time. This pass knocked the cured mender flush with the surrounding concrete throughout. The crack fill sits level. The pitting zones are filled and flat. Both bays now read as a single uniform surface — the boundary between the older and newer concrete is gone. The floor was clean, open, and ready for coating.

Coating Application

The homeowner selected Stoney Creek with Marquita — a dense, dark charcoal blend with grey and white flecks throughout. Our crew applied the MC-4 polyurea-polyaspartic coating system across the prepared 655 square feet. Our team broadcast Stoney Creek flakes into the wet base coat in full coverage across both bays. Our crew carried the coating along the 1–2 inch vertical area under the exterior wall molding. Our team then applied the clear polyaspartic topcoat with 16-grit traction additive throughout.

Finished Floor

Stoney Creek covers all 655 square feet. The dark charcoal and grey blend reads consistently across both bays under both natural light through the windows and the cooler interior light. The control joints pass cleanly through the finished surface — their lines remain sharp beneath the topcoat.

The 1–2 inch vertical edge along the exterior wall sits within the same Stoney Creek finish. The floor meets the wall base with a clean, coated edge throughout. The oil staining, the diagonal crack, and the pitting are sealed beneath the mender repairs and the MC-4 system. The 16-grit traction provides reliable grip across the full floor.

The Starting Point

The 623-square-foot slab at this Bishop property was structurally intact. The control joint grid was well-defined, and the concrete showed no widespread deterioration. Two conditions required attention before coating could begin. Scattered oil staining marked the parking positions — one narrow streak running from a control joint, and a broader pooling zone with branching spread across the adjacent panel. White efflorescence deposits covered portions of the surface, concentrated across the rear panels near the back wall. A crack ran through one of the control joint intersections. The scope included 66 linear feet of verticals along the foundation ledge and 1 step at the house entry.

Surface Preparation

Our crew diamond-ground the full 623 square feet. The grind cleared the laitance layer and removed the efflorescence deposits from the surface of the concrete. The oil-stained zones were opened during the grind — the narrow streak at the control joint and the broader pooling area both received focused passes. Our team applied MR-50 primer directly into the crack at the control joint intersection. MR-50 penetrates the crack and bonds with the surrounding concrete, sealing the joint before the coating system goes down. Our crew worked the primer into the crack and allowed full cure time. The 66 linear feet of verticals along the foundation ledge were prepared to receive the coating alongside the floor. Our team prepared the step tread and riser for the same finish.

Coating Application

The homeowner selected Stoney Creek — a medium grey blend with white and charcoal flecks. Our crew applied the MC-4 polyurea-polyaspartic coating system across all 623 square feet. Our team broadcast Stoney Creek flakes into the wet base coat in full, even coverage across the floor. Our crew carried the same finish along all 66 linear feet of verticals at the foundation ledge. Our team coated the step — tread and riser — in Stoney Creek to match the floor. Our crew then applied the clear polyaspartic topcoat with 16-grit traction additive throughout.

Finished Floor

Stoney Creek runs across all 623 square feet. The medium grey reads evenly across the full slab in both the interior light and the natural daylight at the garage door opening. The control joints cut through the finished surface cleanly on every panel.

The 66 linear feet of verticals carry the Stoney Creek finish continuously along the foundation ledge — the coated base ties floor to wall without a gap at the boundary. The step sits within the same finish. Tread and riser match the floor exactly.

The efflorescence, the oil staining, and the crack at the control joint are gone. The MR-50 sealed the crack at the concrete layer. The MC-4 system covers the full floor, verticals, and step in one consistent finish. The 16-grit traction provides reliable grip across the entire surface.

Hidden Lane, Grosse Pointe, MI

 

The Starting Point

The slab at this Hidden Lane property showed the kind of varied surface damage that builds up over years of garage use. Fluid staining spread across multiple panels — different deposits in different positions, none confined to a single zone. White efflorescence patches had formed across portions of the surface, indicating moisture movement through the concrete. A crack ran diagonally across one of the front panels. Scattered pitting marked the slab throughout. Two small areas carried light paint residue from a prior treatment. The scope covered 531 square feet. Two steps at the house entry were included. No vertical surfaces were in scope.

Surface Preparation and Repairs

Our crew diamond-ground the full 531 square feet. The grind removed the laitance layer, cleared the efflorescence deposits, and opened the concrete across all panels. The light paint residue in the two affected areas came up during the grind without additional treatment. Our team addressed the diagonal crack with mender compound, working it into the full length of the fracture. The pitting distributed across the slab received the same targeted repair — mender worked into each void and brought flush with the surrounding surface. Our crew applied MR-50 primer across the repaired zones to consolidate the surface and ensure bond. Our team prepared both steps — tread and riser — for the coating. Our crew allowed all repairs to reach full cure before the coating phase began.

Coating Application

The homeowner selected Chestnut — a warm blend of reddish-brown, tan, and white flecks. Our crew applied the MC-3.9 polyurea-polyaspartic coating system across the prepared 531 square feet. Our team broadcast Chestnut flakes into the wet base coat in full, even coverage across the floor. Our crew carried the Chestnut finish across both steps — tread and riser on each. Our team then applied the clear polyaspartic topcoat with 36-grit traction additive throughout the floor and steps.

Finished Floor

Chestnut covers all 531 square feet. The warm reddish-brown and tan blend works well against the light block walls of this garage — the color brings warmth to an interior that bare concrete could not. The control joints pass cleanly through the finished surface on every panel, their lines sharp and uninterrupted under the topcoat.

Both steps sit within the same Chestnut finish. Tread and riser on each step match the floor without a break in color or texture. The efflorescence, the crack, the pitting, and the paint residue are all gone — addressed at the concrete layer before the first drop of coating went down. The 36-grit traction provides firm grip across the full floor and both steps.

on Grayton St

Grayton St, Grosse Pointe, MI

 

The Starting Point

The slab at this Grayton St property was 317 square feet — a single-car garage with concrete block walls on three sides. The concrete showed years of accumulated surface contamination: general staining spread across the panels, scattered debris ground into the surface, and a crack running diagonally through the slab. Pitting was present throughout. The condition of the slab pointed to moisture movement through the concrete — a factor that would need to be addressed before any coating could go down. No steps and no vertical surfaces were included in the scope.

Diamond Grinding

Our crew diamond-ground the full 317 square feet. The grind removed the laitance layer and opened the surface of the concrete throughout. After grinding, the crack running through the slab was fully exposed and profiled. Residual staining remained in several zones after the grind — confirmation that moisture had been driving contamination upward through the concrete over time. Our team vacuumed the full surface before moving to crack and pitting repair.

Crack and Pitting Repair

Our crew applied mender compound along the full length of the diagonal crack. Our team worked the material into the seam and troweled it flush with the surrounding concrete. The pitting distributed across the slab received the same treatment — mender packed into each void and brought level with the surface. Our crew allowed all repairs to reach full cure before proceeding to the moisture barrier application.

Moisture Barrier Application

With repairs cured, our crew applied the moisture barrier across all 317 square feet. The residual staining visible after grinding confirmed active moisture migration through this slab. The moisture barrier seals the pore structure of the concrete against upward vapor movement — a step that cannot be skipped when the evidence is present. Our team worked the barrier across the full surface using roller and brush, cutting in carefully along the block wall perimeter. Our crew taped the garage door threshold cleanly before application. The barrier cured fully before the coating system went down.

Coating Application

The homeowner selected Stoney Creek — a medium grey blend with white and charcoal flecks. Our crew applied the MC-4.7 polyurea-polyaspartic coating system across the moisture-sealed 317 square feet. Our team broadcast Stoney Creek flakes into the wet base coat in full, even coverage across the floor. Our crew then applied the clear polyaspartic topcoat with 36-grit traction additive throughout.

Finished Floor

Stoney Creek covers all 317 square feet. The medium grey reads consistently across the full slab under both the natural light from the garage door opening and the cooler light inside. The control joints pass cleanly through the finished surface, their lines uninterrupted beneath the topcoat.

The block wall perimeter sits directly above a clean coating edge — no verticals, no steps, no transitions to manage. The floor runs wall to wall within the defined scope. The crack, the pitting, and the moisture migration pathway are all sealed beneath the repair layer and the MC-4.7 system. The 36-grit traction provides firm, reliable grip across the full surface.

The MotorCity Advantage

MotorCity Floors and Coatings specializes in professional-grade polyurea-polyaspartic systems. These dual-coating systems are replacing epoxy products constrained by older chemistry. Our systems deliver strong chemical resistance, superior durability, greater flexibility, shorter cure times, and proven UV stability that maintains color for decades. We back every installation with an industry-leading warranty.

Each project includes thorough diamond grinding preparation, flexible polyurea crack repair, and careful application to ensure consistent coverage across the full slab. When oil contamination is present — as our crew found at the Blairmoor Court property in Grosse Pointe — we apply a petroleum drawing compound before grinding to draw petroleum from within the pore structure of the concrete before the grind begins. When cracking and pitting are extensive, we apply a full-slab flood coat after repairs and grind twice. Every condition is addressed completely before the first coat goes down.
