Is road salt eating your garage slab? An epoxy or polyaspartic coating over a ground and repaired slab keeps salt and water on top, where you can hose them off. We cover Madison, Sun Prairie, Fitchburg, Middleton, Verona and Waunakee, and the estimate is free.
Three steps take a floor from first call to finished coating.
Call (262) 236-5232 or text a few photos of the floor and a rough size. Cracks, stains and any damp spots are the details that matter.
The floor is measured and checked, including a moisture test. The firm price comes after that, since slab condition moves the cost more than size.
The slab is ground and repaired, then coated. Keep people, pets and cars off it until the product sheet says it has cured.
Quick answer: A coated garage floor in Madison usually runs $4 to $8 per square foot, so a typical two-car garage runs about $2,000 to $4,500 depending on slab condition and finish. Polyaspartic systems usually run $6 to $10 per square foot and can cure fast enough for a one-day job. Prep is the big cost driver, and it is also what keeps a coating from peeling.
The core job. The slab is diamond-ground to open the concrete, cracks and pits are filled, and an epoxy base goes down with a polyaspartic topcoat, often with a flake broadcast for grip. The sealed floor keeps road salt and brine on top instead of in the concrete. Walk-on and drive-on times depend on the product, so follow its sheet.

Polyaspartic cures faster than most epoxy, holds its color in sunlight, and stands up well to wear and chemicals. It is used as a topcoat over an epoxy base or as a full system when you need the floor back sooner. It costs more than epoxy alone.

A coated basement floor turns a dusty or stained slab into a sealed surface you can mop. Moisture decides the job, so the slab is tested first and a moisture-tolerant primer is used when the readings call for it. Ventilate well and keep pilot lights off when solvent-based products are used.

A coating is only as good as the slab under it. Freeze-thaw leaves cracked, pitted and flaking concrete, and it all gets repaired before coating so cracks do not show back through. Slab repair can also be done on its own before you decide on a coating.

Smooth, easy-to-clean floors for shops, warehouses, breweries and showrooms. The system is matched to the traffic, the chemicals and the cleaning the space needs. Commercial floors are quoted per project after a walk-through.

Flake systems in custom color blends, and metallic epoxy with a marbled look for finished basements, showrooms and garages. They use the same grind and repair prep as any coating. A clear topcoat with grit protects the finish and adds grip.

A coated garage floor usually runs $4 to $8 per square foot, so a two-car garage is often about $2,000 to $4,500. Polyaspartic systems usually run $6 to $10 per square foot, and decorative finishes $6 to $12. The slab and the prep it needs drive the price, so a firm number comes after the floor is measured and checked.
Many garage jobs take one or two days, and a full polyaspartic system can sometimes go down in one. When you can walk on it, park on it, or set things back depends on the product and the temperature, so follow the product sheet. Keep people and pets off the floor until it says the coating has cured.
A coating only bonds to open, clean concrete. Diamond grinding opens the surface, cracks and pits get filled, and a moisture test tells you whether the slab is ready. Skip those steps and the coating can peel, which is the usual story behind a failed store kit.
Often, but test the slab first. If the moisture reading is high, a moisture-tolerant primer goes down, or the water source gets fixed before any coating. Basements also need fresh air during the work, and pilot lights on water heaters and furnaces should be off when solvent-based products are used.
Bare concrete soaks up salty meltwater, and freeze-thaw turns that into pitting and flaking. A coating bonded to a ground slab seals the surface, so the salt sits on top and rinses off.
Warm tires can soften a weak coating and pull it off the floor as they cool. It shows up most on thin store kits rolled over a slab that was not ground. A ground slab with a tough topcoat holds up much better.
