Home / Services / Epoxy garage floors
The epoxy regret we read about most had nothing to do with color. The installer did not grind the old residue down to concrete, and now you can see the old floor through the epoxy, or it peels under the tires. Coatings bond to clean, ground concrete, and skipping the grind is the shortcut you can't see on day one. Call (786) 686-1048 and we'll connect you with an independent floor coating contractor serving your part of Miami-Dade. Ask what grinder they use on the whole floor, whether they test the slab for moisture, and what they add to the topcoat so it isn't slick when wet.
The crew ran a small grinder around the edges, or acid-washed it instead, and the coating went on top. It looked fine for a few months. Then it lifted under the tires. Ask to see the floor after grinding and before the first coat goes down.
Moisture coming up through the slab pushes the coating off from underneath. In a humid climate, or on a slab that floods in a heavy rain, it has to be tested and dealt with before coating.
The weekend kit came with a roller and an etch, and part of the floor stayed sticky or peeled within a year. Some Miami homeowners have done it themselves and been happy. The ones who weren't mostly skipped the grind.
Thinking about coating the garage floor? Call and we'll connect you with a floor coating contractor serving your area.
Call (786) 686-1048Ask for a full diamond grind with a walk-behind grinder, cracks and pits filled, dust vacuumed, then the coating. A quote that says acid etch only, or a whole job in a single day with no grinding, is the warning sign.
Skipped prep showed up in 17 of the 132 stories we read, more than anything else.
Ask whether they test the slab's moisture before coating and what they do if it's high. Read the warranty for a moisture exclusion: in some stories, "moisture" is how a warranty claim got turned down after the floor failed.
Fifteen people described bubbles, or moisture pushing the coating up from below.
Rain blows in under a Miami garage door and wet tires track it in. Ask for an anti-slip aggregate in the topcoat and stand on a wet sample before you choose.
Twelve homeowners said theirs gets slippery when wet, flakes or no flakes.
The two Miami prices in our research were do-it-yourself jobs: about $1,100 for a two-car garage including a rented grinder, and a Doral homeowner who did it for "about 1/3 or less" of a quote they'd had. A hired job costs more because of the grinding equipment, the coating system and the labor. The contractor quotes after seeing the slab.
What moves the number: garage size, cracks and pits to fill, removing old paint or coating, the system (epoxy base with a polyaspartic or urethane topcoat is common), full or partial flake, and the anti-slip additive.
Many epoxies yellow in sunlight, and the first few feet inside an open garage door get the most. A UV-stable topcoat keeps that strip the same color as the rest.
Tires coming off a hot road can pull a poorly bonded coating up. Good prep is the fix; mats are the workaround installers suggest after the fact.
A brand-new garage slab needs to cure for months before coating. How long depends on the slab, and the contractor should tell you.
Say it's a garage floor and give your zip code. You're put through to a coating installer who works your area.
Cracks, old coatings, moisture, and the size.
Grind, repairs, system, flake and topcoat, itemized.
Full grind, cracks filled, dust removed.
Base, flake, topcoat. Walk on it when they say, park on it after the full cure.
A busy full-flake floor hides small parts. If you work on cars or projects in the garage, a lighter flake blend or a solid color helps.
That's usually an epoxy topcoat in the sun. If your garage door stays open, a UV-stable topcoat is worth paying for.
A new topcoat with an anti-slip aggregate mixed in fixes most floors. Rugs at the door help in the meantime.
Test the slab for moisture first, coat on a dry day with the door closed if it's humid, and use a system rated for the moisture level found. Bubbles from slab moisture can't be fixed by more coats on top.
How they grind and how much of the floor, whether they test moisture, which base and topcoat products, whether the topcoat is UV-stable and anti-slip, what the warranty excludes, and when you can park on it.
A kit can work if you grind the whole floor properly, which means renting a grinder. Most kit failures come from rolling it onto etched or dirty concrete. A professional job costs more and should come with real prep and a warranty.
