Frequently Asked Questions

HomeGuide puts installed epoxy nationally at $4 to $10 per square foot, with two-car garages at $1,600 to $5,800. Polyaspartic runs $5 to $12 a square foot. Removing old coatings, repairing cracks and adding flake or metallic finishes move the total, so we price each floor after we see and test it.

Plain epoxy can be slippery when wet, it yellows in sunlight, and it needs several days to cure fully. It also peels when it goes over damp or unground concrete. Texture, a UV-stable topcoat, a moisture test and proper grinding deal with each of those.

For garages that see sun or a lot of road salt, polyaspartic often outperforms plain epoxy because it resists UV and cures in 1 to 2 days. Plenty of floors combine the two, with epoxy underneath for thickness and a polyaspartic topcoat for wear. For a basement out of the sun, epoxy alone usually does the job.

Yes. Concrete is what these coatings are made for. The slab has to be ground, clean, repaired and dry enough, which is why we test moisture before quoting. We do not coat over wood, tile or vinyl.

A sealed, chemical-resistant topcoat holds brine up on the surface so it never gets into the concrete. Rinse or squeegee the floor every so often through winter so salt does not sit for weeks. The coating protects the slab; the rinse keeps it looking clean.

Often, yes, but the slab and air have to be warm enough for the resin to set properly. A heated garage or basement can usually be coated most of the year. In a cold detached garage we may suggest waiting for milder weather or using a faster-curing system.

HomeGuide lists DIY kits at $200 to $700. Most kits are thin and count on an acid etch where a grinder belongs, so they tend to peel under hot tires and winter brine. If a kit has already failed, it has to be ground off before a new system goes down.

HomeGuide puts solid epoxy at 10 to 20 years and thin water-based products at 3 to 5. In a garage that takes winter brine, the topcoat and the prep decide where a floor lands in that range. Grinding, a tough topcoat and rinsing salt off in winter all help.

In a heated garage, often yes. In an unheated garage the slab can be too cold for the coating to cure properly, so we may suggest a faster-curing system or a milder week.

Yes, the floor needs to be clear for grinding and coating. Shelving that is bolted to the wall can usually stay if its feet are off the floor.

Hot tire pickup is mostly a problem with thin kit coatings or floors that skipped grinding. A ground slab and a full-strength system bond far better than a rolled-on kit.

Plain gloss gets slippery once it is wet. That is why we mix in anti-slip aggregate or flake, especially near the door where melting snow lands.

Usually not. Under the topcoat, the chips create a light texture. For extra grip by the door or on steps, we mix anti-slip grit into the last coat.

Much less than solid colors. Mid-tone mixed blends hide both dried salt film and tire marks well between rinses.

Yes. Partial flake is popular in basements and gyms. The slab still needs grinding and a moisture test before coating.

They are the same thing. Chip, flake and vinyl flake all refer to the colored vinyl pieces broadcast into the base coat.

It is better at some things: UV resistance, cure speed and abrasion. Epoxy builds thickness and is cheaper. That is why lots of garages get both, with epoxy as the base and polyaspartic as the topcoat.

HomeGuide says heavy vehicles can usually return after 24 to 48 hours, and Bob Vila puts cars at about 24 hours. Cold slabs slow that down, so we give you dates for your floor.

It cures across a wider temperature range than epoxy, which helps in spring and fall. Slab and air still need to be within the product's limits, so we measure before coating.

Not really. It sets fast, so it is easy to leave lap marks or run out of working time. Bob Vila also describes it as not for DIY.

Yes, with care. It needs added slip texture for snowmelt and a UV-stable topcoat for sun through the door. Many people choose metallic for a basement and flake for the garage.

It will be close in color and style, but every metallic floor is unique because it is worked by hand. That is part of the appeal.

A full gloss can be slick when wet or in socks. A satin topcoat or fine anti-slip aggregate makes it safer.

Not directly. Any old coating is ground off first so the new system grips bare concrete and the finish stays smooth.

It depends on the system and the size of the floor. Polyaspartic topcoats can return a floor in a day or two, while thicker epoxy builds take longer. Phasing the job lets you keep some of the space in use.

Sometimes, if it is well bonded and compatible. Peeling or unknown coatings are ground off first. We test before we decide.

Industrial systems are usually thicker, 100% solids epoxy builds with tougher topcoats, made for forklifts, chemicals and constant traffic.

Yes. A one-bay shop or a small storage building gets the same prep and testing as a large warehouse, sized to the job.

It depends on how damp. The moisture reading shows us whether a standard system will hold, whether it needs a vapor-tolerant primer, or whether the water source has to be fixed first.

For storage, laundry, gyms and playrooms, a coating is easier to clean and does not hold moisture or odors. You can still add area rugs on top.

Most basements take a few days from grinding to final coat, then cure time before furniture goes back. We give you dates in the quote.

No. We grind off old paint and adhesive first, so the new coating grips the bare slab.
