Frequently Asked Questions

Standard epoxy tends to yellow in spots that get sunlight, and HomeGuide notes a full cure can stretch to about a week. It also needs real surface prep; on a damp or poorly ground slab it can peel. We reduce those risks with moisture testing, diamond grinding and a UV-stable topcoat where the floor sees light.

Per HomeGuide, installed epoxy runs $4 to $10 per square foot nationally: about $1,200 to $3,900 for a one-car garage, $1,600 to $5,800 for a two-car and $2,300 to $8,600 for a three-car. Old coatings, crack repair and chip or metallic finishes change the total. We price your floor after an on-site visit.

It depends on the room. For Chicago garages, polyaspartic, either as the topcoat or as the whole system, often makes more sense, since HomeGuide gives its UV resistance an excellent rating and it can take vehicles in 24 to 48 hours. For a damp basement that fails a moisture test, a breathable sealer may be the better choice than any coating. We will tell you which fits.

In a heated, attached garage, often yes. In an unheated alley garage during the coldest weeks, usually not, because the coating will not cure properly unless both the concrete and the air stay warm. We check the conditions and give you a realistic install window.

It can work well when the slab clears moisture testing. Basement epoxy makes a floor brighter, easier to clean and sealed against spills. The downside is that moisture pushing up through an older slab can lift a coating, so testing comes before anything else, and high readings mean either a moisture-tolerant primer or a different finish altogether.

Per HomeGuide, cars should stay off epoxy for roughly 2 to 7 days, while polyaspartic can usually take heavy vehicle traffic in 24 to 48 hours. Your quote will list the exact walk-on and park-on times for the system we install.

Yes. We can split a shared basement into sections and give you a written schedule to share with tenants, so laundry and storage stay reachable during the work.

HomeGuide puts solid epoxy at 10 to 20 years and polyaspartic at 10 to 20+ years, while thin water-based products last 3 to 5 years. In Chicago, how well the slab was prepped and how often salt is rinsed off matter as much as the product.

Salt is hard on bare concrete, but a well-bonded coating sealed under a topcoat made to resist chemicals holds up against it. Rinse the floor through the winter so dried salt does not pile up and dull the finish.

In a heated garage, often yes. For an unheated alley garage, we usually hold off until milder weather, since the coating cannot cure unless the slab and the air stay warm.

HomeGuide lists DIY kits at about $200 to $700. Most are thinner water-based products, and without diamond grinding they often lift under hot tires. On a salted Chicago floor, a professionally ground and coated slab lasts far longer.

HomeGuide advises keeping cars off epoxy for about 2 to 7 days. Polyaspartic can usually take vehicles in 24 to 48 hours. Your quote lists the exact times for the system we install.

Full-broadcast chip floors have natural texture, and adding grit to the topcoat increases grip. They are much less slippery than a smooth, solid-color coating when wet.

For most Chicago garages, yes. The chips hide salt, dust and small slab flaws, and the texture helps with meltwater. Solid colors look sleek but show every footprint.

Mid-tone grays and tans hide dried salt most easily. Very dark blends show white residue, and pale blends reveal tire marks.

Yes, provided the slab clears moisture testing. Many people choose a partial broadcast in finished basements and a full broadcast in laundry and storage areas.

For most garages, the work itself runs one to two days, with prep and the chosen system setting the pace. How long you wait to park depends on the topcoat, and we give you exact times.

For a garage that gets sun and has to be usable again quickly, often yes. HomeGuide scores its UV resistance excellent; epoxy gets a poor to fair rating on the same measure. Epoxy builds thicker per coat, so many floors use both.

HomeGuide says heavy vehicle traffic is usually fine after 24 to 48 hours. Bob Vila gives 3 to 4 hours before walking and about 24 hours before vehicles. We give you the time for your system.

Bob Vila calls it not a DIY product. It sets quickly once mixed, so it needs experience and full prep to go on evenly.

HomeGuide gives 10 to 20 or more years. Prep quality and how often salt is rinsed off make a big difference.

Yes, provided the slab clears a moisture test. They are popular in basement rec rooms and bars. Testing comes first, and when the readings call for it we lay down a primer built to tolerate moisture.

You can, but road salt, hot tires and grit are hard on a glossy finish. For most Chicago garages, a chip floor is more practical.

The clear topcoat can scratch from grit and dragged furniture. Dust mop often and use felt pads. The topcoat can be refreshed later.

This Old House puts metallic systems at $5 to $12 per square foot. Leveling, the number of colors and the topcoat change the total, and we give you a written price.

It depends on the size and system. Bob Vila notes a polyaspartic floor may close a business for only a day or two. We can also work in sections or after hours.

Yes, when it is a thick system with slip texture and a cove base. It seals the concrete and makes cleanup easier.

Usually, after grinding or shot blasting to sound concrete and testing for moisture. Oil-soaked or crumbling areas are repaired first.

Yes. We can paint walkways, forklift lanes, storage zones and keep-clear areas as part of the job.

Pros: a bright, sealed, easy-to-clean floor that stops concrete dust and resists spills. Cons: high slab moisture can lift it, it does not stop water leaks, and a glossy finish can be slick when damp. Testing and texture address most of the cons.

Yes, on every basement. We test during the estimate and recommend a moisture-tolerant primer or another finish when readings are high.

Yes, after we grind the paint off. A new coating will not hold well over old paint, so it all comes off first.

No. A coating does not stop water coming through cracks or walls. That needs drainage or foundation work first, and we will point it out if we spot signs of it.

It is a hard surface, like the concrete under it. Many people add area rugs in finished rooms, which is fine on a coated floor.
