How an Epoxy Garage Floor Job Runs
A garage job starts with a walk-through, a moisture test and a crack map, then a written scope. On the install day we grind the slab, fill cracks and spalls, apply the base coat and broadcast, and finish with a topcoat, so you know exactly when you can walk on it and when you can park.
Attached Garage Dust and Odor Control
Most Glenview houses with a garage have an attached one, which puts the grinder and the resin a doorway away from the kitchen. We run vacuum-shrouded grinders, seal the house door, ventilate the garage and pick low-odor products, so dust and fumes stay in the garage instead of drifting into the house.
Detached Garage Floors That Sit Cold
A detached garage usually has no heat, which means its slab spends the winter cold and swings through freeze and thaw. We schedule these floors for the warmer months, pick a system rated for the temperature range the slab will actually see, and check whether the slab has a vapor retarder under it at all.
Vapor Retarders Under Older Garage Slabs
Many attached-garage slabs from the 1950s to 1970s were poured with no vapor retarder, because the model code exempted garages. Glenview’s Ordinance 6589 narrows that exception to detached garages, so a newer attached slab should have one. Either way, we test the slab instead of assuming what is underneath.
Moisture Testing a Garage Slab
We use the ASTM D4263 plastic sheet test as a first read and an ASTM F1869 calcium chloride test or ASTM F2170 in-situ relative humidity probes when the job calls for a number. The result decides whether the floor gets a standard primer or a moisture-mitigation primer, before the price is set.
Garage Floor Cracks, Spalls and Pitting
Cracks are chased and filled, spalls are rebuilt and pitting is ground smooth before any coating goes down. When a slab has heaved, sunk or broken into loose plates, a coating will only outline the damage, and we tell you the slab should be replaced first rather than coating over it.
Road Salt Damage on Bare Concrete
Calcium chloride and rock salt deicers soak into bare concrete and drive scaling as the slab freezes and thaws, which is why so many older Glenview garage floors are pitted at the tire path. A sealed epoxy or polyaspartic surface keeps the brine on top, where a squeegee and a rinse take it away.
Cold-Weather Garage Coating
Resin floors need a minimum slab temperature and a slab that stays above the dew point while they cure, or they cure soft and cloudy. We measure slab temperature and dew point spread on the day, and an unheated garage in deep winter is told to wait for spring rather than coated anyway.
Hot Tire Pickup on Cheap Coatings
A tire that has just come off the road is hot and soft, and as it cools on the floor it grips and pulls at the coating beneath it. A thin coating on a poorly prepared slab lets go under that pull, so we build thickness on a ground surface and seal it with a topcoat rated for tire traffic.
DIY Epoxy Kits Versus a Built-Up Floor
Store-bought kits are mostly thin, water-based epoxy over an acid etch, which is why they peel at the tire path within a year or two. A professional floor is ground to profile, built from 100% solids epoxy or polyaspartic in measured coats, and broadcast and topcoated, so it is many times thicker and far better bonded.
What an Epoxy Garage Floor Costs
The price moves with the garage’s size, the amount of crack and spall repair, any old coating that has to be ground off, the moisture result and the system chosen. A full flake broadcast with a polyaspartic topcoat costs more than a solid color floor, and our quote breaks out each of those so the number makes sense.
