Upgrading Garage Floor Coating in Ann Arbor with Polyurea-Polyaspartic Coatings
On this page, we document 12 projects of garage floor coating in Ann Arbor, MI. Our dual-coating systems have converted worn concrete slabs into durable, attractive garage floors. Ann Arbor is a Washtenaw County city with a varied housing stock—from historic neighborhoods near the university to established residential streets with decades-old homes.
Many of the properties where we apply our polyurea-polyaspartic floor coating systems had accumulated the wear and tear of the harsh climate of Michigan. As you will see in these 12 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 significant remediation—oil extraction, moisture barrier application, and crack and pitting repair—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.
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, and surface pitting.
Several of our jobs of garage floor coating in Ann Arbor involved concrete with persistent oil contamination penetrating deep into the slab—a condition that grinding alone cannot resolve. Polyurea-polyaspartic systems provide reliable protection against these conditions and deliver an appearance that bare concrete or epoxy products cannot match.
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 deep oil contamination is present—as our crew found at a home on Overridge Dr.—we perform oil extraction before grinding. This step prevents petroleum from migrating through the concrete and undermining the coating bond.
Ann Arbor Garage Floor Coating Case Studies
These 12 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 show the consistent quality standards MotorCity Floors and Coatings applies to every installation.
NEW Garage Floor Coating
on Brackley Drive
Brackley Drive — Ann Arbor, MI
Project Overview
MotorCity Floors and Coatings installed the MC-3.7 coating system at a garage on Brackley Drive, Ann Arbor. The project covered 371 square feet of floor, two steps, and 39 linear feet of 20-inch verticals. Importantly, the concrete required no crack repair — the slab was sound throughout. Our crew applied Sandstone flakes at H-4 density with a 16-grit traction additive.
Initial Substrate Condition
The slab was in good structural condition with no cracking or spalling. Light staining from normal vehicle use appeared near the center of the floor. The vertical surfaces showed raw, unpainted concrete along the perimeter. The two entry steps were bare concrete with no previous coating.

NEW Garage Floor Coating
on Country Club Road
Country Club Road — Ann Arbor, MI
Project Overview
This 707-square-foot garage on Country Club Rd had a deteriorated epoxy floor. MotorCity Floors and Coatings stripped the old coating and addressed pitting and cracks below. The project also required working around a center-slab floor drain. Our crew finished with the MC3.8 system in Silver Creek with 16-grit traction
Condition of the Existing Epoxy
Oil pooling had concentrated near the floor drain in the center of the slab. The drain area showed the heaviest surface staining of any zone in the garage. Contamination around the drain penetrated below the existing epoxy.

NEW Garage Floor Coating
on Hensley Drive
Hensley Drive — Ann Arbor, MI
Project Overview
This Hensley Dr. garage had freshly poured concrete ready for its first coating. MotorCity Floors and Coatings installed the MC3.8 system on 594 square feet. The scope included the main floor, 7 linear feet of step risers, and step treads. Our crew used Pebble Beach flakes with 16-grit traction in the top coat.
Surface Preparation on New Concrete
New concrete requires grinding before any coating can bond to it. Concrete curing compounds and surface laitance block direct adhesion. Our crew ground the full 594 square feet to open the slab surface. Grinding removed the curing layer and created a mechanical profile for bonding. Our team vacuumed the ground surface before any material touched the floor.

NEW Garage Floor Coating
on Oak Ravine Court
Oak Ravine Ct — Ann Arbor, MI
Project Overview
MotorCity Floors and Coatings coated a 17-year-old garage on Oak Ravine Ct in Ann Arbor. The floor measured 1,110 square feet with 58 linear feet of block wall verticals. Our crew installed the MC-4.9 system with Silver Creek flakes and 16-grit traction. Moisture testing confirmed no moisture barrier was necessary before coating.

NEW Garage Floor Coating
on Overridge Drive
Overridge Drive — Ann Arbor, MI
Project Overview
The homeowners on Overridge Dr. contacted MotorCity Floors and Coatings for their garage. The attached 540-square-foot garage had accumulated years of vehicle use and neglect. A connected 21-square-foot workroom featured a wood floor with its own boundary condition.
Our crew identified three primary challenges before work began: oil saturation, surface damage, and elevated moisture.
The homeowners selected the Pebble Beach color in the MC4 coating system.
Initial Substrate Condition
Our crew conducted a thorough inspection of the full slab before planning the work sequence. The concrete showed crack patterns running in multiple directions across the floor. Surface pitting appeared throughout the slab, concentrated near the garage door opening.
Freeze-thaw cycles had opened and widened the surface voids over time. Oil contamination covered several distinct zones under each parking position. The dark saturation indicated petroleum had penetrated well below the concrete surface. Moisture readings near the perimeter walls exceeded acceptable levels for direct coating. That finding placed a moisture barrier in the required scope of work.

New Garage Floor Coating
on South Ridgemont Lane
South Ridgemont Lane — Ann Arbor, MI
Project Overview
This 545 square-foot garage on South Ridgemont Ln is the 8th case study of our garage floor coating work in Ann Arbor.
The existing surface had an old epoxy coating over heavily pitted concrete. Our crew removed the epoxy, repaired the pitting, and applied the MC3.8 system. The project finished with an Aztec Beige flake blend and 24-grit traction.
Initial Substrate Condition
The floor showed an old epoxy coating across the entire slab. This clear epoxy coating is not very visible on the photos but you can see the yellowish, milkish tint typical of aging expoxy: as its chemicals break down, UV resistance decreases and sun exposure bakes the top layer.
Oil stains and surface contamination appeared throughout. Cracks traversed the slab between expansion joints. The concrete had no steps and no vertical surfaces.
The epoxy coating showed peeling and adhesion failure. Grinding revealed the full extent of the pitting below. The pitting spread across both slabs of the garage floor.

NEW Garage Floor Coating
on Doral Drive
Doral Drive — Ann Arbor, MI
Project Overview
Initial Substrate Condition
The slab showed two distinct paint layers across the full floor. A white coat sat over an older grey coat beneath. Neither layer had maintained adhesion at the control joints. Peeling and separation appeared along each seam throughout the slab.
The control joints held packed caulk beneath the paint layers. The caulk had compressed and separated over time. Light pitting appeared in isolated zones of the slab. The concrete step carried surface staining on the tread and riser face.

New Garage Floor Coating
on Stonebridge Drive North
Stonebridge Drive North — Ann Arbor, MI
Project Overview
Initial Substrate Condition
The slab showed a long diagonal crack running across one panel. Oil staining and surface wear appeared near the vehicle parking positions. The cracking was concentrated on the left side of the garage. The right side of the slab had less damage and required less repair.
Pitting on the more affected side ranged from shallow surface voids to open aggregate. The concrete step showed general wear on the tread face. The 31 linear feet of vertical lip ran along the perimeter walls and required coating. No prior coating was present — the slab was bare concrete throughout.

NEW Garage Floor Coating
on Hayster Drive
Hayster Drive — Ann Arbor, MI
Project Overview
Initial Substrate Condition
The slab was bare concrete with no prior coating to remove. Surface staining from vehicle parking was present across the main driving area. Moisture was wicking through the concrete — visible along the perimeter wall and the base of the vertical lip. The two wood steps leading to the house door showed general wear and carried a prior paint coat.
The 58 linear feet of vertical lip ran along three walls of the garage. This is one of the larger lip areas our crew encounters on residential jobs. No cracking or pitting was present — the slab required no structural repair before coating.

FAQ
Find answers to your technical questions about polyurea-polyaspartic garage floor coatings.
Three traction grit options are available: 16-grit for a standard finish, 24-grit for moderate texture, and 36-grit for maximum slip resistance in wet or icy conditions. The grit additive is incorporated directly into the polyaspartic clear coat before application, so it does not alter the visual appearance of the finished floor.
Flake broadcast density controls how much of the base coat remains visible through the chip layer. H-4 density gives an open, lighter pattern with visible concrete texture between chips. H-6 density produces tight, full-coverage results. Both densities use the same flake blends — density selection changes coverage, not color.
Wooden steps are handled differently because wood requires mechanical abrasion rather than diamond grinding before a polyurea-polyaspartic system can bond to it. Each tread and riser is abraded by hand, then coated with the same base coat and flake broadcast as the main garage floor for a continuous finished appearance.
Coverage depends on slab condition and system version. Across the Ann Arbor projects documented here, floor areas ranged from 371 to 1,110 square feet within a single installation day. Each layer — base coat, flake broadcast, and clear coat — is applied in full across the entire prepared surface regardless of floor area.
