Quick answer: In Madison, a coated garage floor usually runs $4 to $8 per square foot, a polyaspartic system runs $6 to $10, a basement floor runs $4 to $9, and decorative flake or metallic finishes run $6 to $12. A typical two-car garage lands around $2,000 to $4,500. Slab condition and prep are the biggest variables, which is why we quote after seeing the floor.
A quick note on these numbers. Everything below is a reference range to help you budget, not a firm quote. Every job is different, and the only honest way to give you a real number is after a free inspection. Use the figures below to plan and to vet other contractors' quotes; call us at (608) 736-1143 when you want the actual quote on your specific job.
| Coating | Usual price per sq ft | Best for |
|---|---|---|
| Epoxy garage floor | $4 to $8 | The standard durable, sealed garage floor. |
| Full polyaspartic system | $6 to $10 | One-day install, max durability and UV resistance. |
| Basement floor coating | $4 to $9 | Finished or moisture-prone basement slabs. |
| Decorative flake / metallic | $6 to $12 | Showrooms, finished spaces, high-end garages. |
| Standalone slab repair | $300 to $1,200 | Cracks and spalls before a coating decision. |
| Commercial / industrial | Per-project quote | Shops, warehouses, breweries, clinics. |
The number one reason a floor coating fails is bad prep, and it is exactly what a hardware-store kit and a cheap quote skip. Concrete has to be mechanically opened up, by diamond grinding or shot blasting, so the coating bonds into the surface instead of sitting on top of it. Cracks and pits have to be repaired, and the slab has to be moisture-tested, because vapor pushing up through an older Madison slab will lift a coating that was not built for it. When you see a low per-square-foot price, the difference is almost always in the prep: a quick acid-etch and a thin roll-on versus a real grind, repair, and a base-plus-topcoat system. We price the prep your slab actually needs, which is why our coatings hold up to road salt and freeze-thaw for years instead of peeling in a season. The square-foot rate also drops as the floor gets bigger, so a large garage or a commercial slab costs less per foot than a small one.
These ranges reflect real coated floors across the Madison area. We are an insured, manufacturer-certified floor-coating contractor, we diamond-grind and moisture-test every slab, and we use base-plus-topcoat epoxy and polyaspartic systems built for a salt-and-freeze climate. We will share a certificate of insurance on request, and we will tell you honestly when a simpler finish does the job.
A coated garage floor usually runs $4 to $8 per square foot, so a typical two-car garage lands around $2,000 to $4,500. Polyaspartic systems run $6 to $10 per square foot and decorative finishes run $6 to $12. The biggest variable is slab condition, since a cracked or moisture-prone floor needs more prep, which is why we quote after seeing it.
Because the kit skips the part that makes a coating last. A real install diamond-grinds the slab, repairs cracks and pits, moisture-tests, and applies a base-plus-topcoat system, so it bonds and holds up to salt, hot tires, and freeze-thaw. A roll-on kit over an acid-etched floor usually peels within a season or two, so the cheap option ends up costing more once you pay to fix it.
Epoxy is the durable, cost-effective base coat. Polyaspartic cures much faster (allowing a one-day install), resists UV without yellowing, and is tougher against abrasion and chemicals, so it is the premium topcoat or full system. Most of our floors use an epoxy base with a polyaspartic topcoat, which combines the strengths of both at a sensible price.
Yes. The per-square-foot rate drops as the floor gets larger, because setup, grinding, and mobilization are spread over more area. A small one-car garage costs more per foot than a big three-car garage or a commercial slab. We give you the all-in number for your specific floor, not just a per-foot teaser rate.
We repair cracks and spalls as part of the prep so they do not telegraph back through the finish, and a decorative flake system in particular does a great job of hiding minor imperfections and old stains. A solid-color coating shows the floor’s flatness more, which is another reason flake finishes are popular. We tell you up front what your slab will and will not hide.
A properly prepped and installed epoxy-polyaspartic floor commonly lasts 10 to 20 years in a residential garage, even with Wisconsin salt and freeze-thaw, because the prep and the topcoat are built for it. The coatings that fail early are almost always the ones with skipped prep. We back our work and the systems we install carry a manufacturer warranty tied to correct application.
