How an Epoxy Garage Floor Job Runs
A garage job starts with a slab walk, a moisture check and crack mapping, then a written proposal. Install day begins with grinding and repair, followed by the base coat, broadcast and topcoat, with the return-to-parking date set by the product and the slab temperature.
Staging Alley Garage Coatings from the Alley
Many Cicero garages sit at the back of the lot and open onto an alley. We stage grinders, vacuums and mixing from the alley side, so the yard and the house stay clear and neighbors sharing the alley can still pass.
Grinding Through Sealer and Old Paint
A coating rolled over sealer or garage-floor paint can only bond as well as that old layer holds the concrete. Diamond grinding removes the old film and opens the pores, so the new epoxy anchors to sound concrete instead of peeling off with the paint underneath it.
Moisture Testing a Garage Slab Without a Vapor Retarder
The residential code lets a detached garage slab skip the under-slab vapor retarder, so many garages have nothing stopping ground moisture. We test before pricing, using a plastic sheet screen or calcium chloride kits, and specify a primer that tolerates vapor where the numbers call for one.
Repairing Cracks and Spalls Before Coating
Cracks, spalls and pitting are filled and ground flush before any coat goes down. When a slab has settled, heaved or broken into loose pieces, we say so plainly, because coating a floor that needs replacing only hides the problem for a season.
What Brine and Rock Salt Do to Bare Concrete
Calcium chloride and rock salt melt snow on the street, then drip off the car and soak into a bare garage slab. Repeated freezing and thawing of that salty water scales the surface and pits the paste, which is why an unprotected slab looks worn long before its age.
Coating a Garage in Cold Weather
Most epoxies need the slab, not just the air, to sit above a minimum temperature and stay several degrees above the dew point while they cure. An unheated garage in January often fails both tests, so we schedule it for a warmer stretch or a heated enclosure instead.
Hot Tire Pickup and Cheap Coatings
A tire coming off a warm highway softens a thin coating and, as it cools, pulls the film up off the floor. Hot tire pickup is common with thin single-part paints over unground concrete, and a ground slab with a full-build epoxy and a hard topcoat is the cure.
Store-Bought Kits Compared with a Professional Floor
A retail kit usually relies on an acid etch and a thin water-based epoxy, often a few mils thick. A professional floor is ground, repaired, built up with 100% solids epoxy and finished with a polyaspartic or urethane topcoat, which is the difference between a seasonal finish and a long-lived floor.
What an Epoxy Garage Floor Costs
Published prices for a coated two-car garage in the Chicago area run roughly $1,800 to $4,500. Crack repair, old coatings that must come off, moisture mitigation and the choice of flake or metallic system all move the number, and each line shows up separately in our proposal.
Coating Warranty Exclusions, Starting with Moisture
Moisture rising through the slab is the exclusion most coating warranties name first. We explain it, along with chemical and impact limits and cracks that move after installation, before the job is sold rather than after something goes wrong.
