Coated garage floors for Miami houses.
Miami proper is a city of houses, not towers. The garages we coat here are attached one and two-car bays on 1950s and 1960s single-family lots in Shenandoah, Westchester and The Roads, plus older detached garages and carports behind the wood-frame houses in Coconut Grove. A lot of them have been converted at some point into a laundry room, a workshop, or a spare bedroom with the door still on the front. Every one of those uses puts different demands on the slab, and the walk-through is where we sort out which system belongs on yours.
The slabs themselves are old, and that is the honest starting point. A garage poured seventy years ago in Coral Way has seen settling, patch jobs, a chased-in plumbing line or two, and decades of oil. Some were never sealed at all. We do not coat over that history, we grind it off. Diamond grinding opens the concrete to a clean profile, crack chasing fills the moving joints, and only then does anything liquid touch the floor. It is slower than rolling a kit out of a box, and it is the entire reason our floors are still flat at year ten.
Moisture testing is not optional on this side of the county. Miami sits on porous limestone with a water table close to the surface, and a slab poured before vapor barriers were standard practice will push moisture up through itself year-round. Coat a wet slab and the finish blisters and lets go within a season, no matter how good the product was. We run calcium-chloride or relative-humidity readings on every floor and spec a vapor-barrier primer when the numbers ask for it. If the readings say wait, we tell you to wait.
Coverage across Miami.
We work throughout the city: Shenandoah, The Roads, Coconut Grove, Westchester, Little Havana and the Calle Ocho corridor, and the residential streets running down toward Biscayne Bay. See the full Miami service page for everything else we install here.
Three things we will not skip on a Miami garage.
Nearly every failed garage floor we get called to repair skipped at least one of these. They are where the cost lives, and they are the reason a coating either lasts a decade or peels by next summer.
Polyaspartic topcoat
UV-stable and scratch-resistant, so an open garage door facing west all afternoon does not amber the finish. It cures fast enough to park on in 48 hours.
Slab moisture testing
CSP 2-3 diamond grind, crack chase, then a vapor reading on an old Miami slab before we commit to a system. Vapor-barrier primer goes down when the numbers call for it.
Flake broadcast or solid
Chip blends in more than thirty color mixes, or a solid color with a non-slip topcoat. Flake hides dust and tire marks, which matters in a garage that doubles as storage.
The longer answer on garage floor epoxy.
The system we install is built in layers and every layer has a job. Primer bonds to the cement matrix and, on a moisture-active slab, blocks vapor drive from below. The basecoat gives the floor body and carries the UV protection. The flake or aggregate layer builds texture, which is what keeps the surface from turning into a skating rink when a wet car drips all over it in August. The topcoat seals everything and takes the abuse. Pull a layer out to shave the price and you cut the lifespan roughly in half.
The Miami garages we coat most.
These are the four scopes that make up most of our residential work inside the city. If your space does not look like any of them, say so on the phone and we will bring the right system to the walk-through instead of guessing.
Attached single-family garages
The standard one and two-bay garages on Shenandoah, The Roads and Westchester lots. Grind one day, coat the next, and you are parking on it inside 48 hours after the final coat goes down.
Detached garages and carports
Older Coconut Grove properties and Little Havana lots where the garage sits off the back of the house or the slab is a covered carport open on two sides. Open-air slabs get extra attention on the edges, where rain drives in sideways and lifts a weak coating first.
Converted garages and workshops
Bays turned into a gym, a laundry, a studio, or a workbench with a car still sharing the space. These get a harder topcoat and a slip profile you can stand on barefoot, because the floor stops being a parking pad and starts being a room.
Storage-first garages
The garage that holds the shutters, the generator, the bikes and eight bins of everything else. A flake finish hides scuffs from dragging heavy things around, and the sealed surface means a spilled gas can wipes up instead of staining.
Humidity, hurricane season, and salt off the bay.
Ask anyone who has lived here through a storm week what the garage is for. It is the room where everything ends up: the patio furniture, the plants, the grill, the shutters that came down off the windows, the bins nobody wants to carry inside. That is a lot of heavy things getting dragged across bare concrete in a hurry, and bare concrete dusts, stains and chips under exactly that kind of use. A sealed floor takes it and cleans up after.
One more Miami-specific note. Plenty of these garages are older than the code that would require a moisture barrier under the slab, so we treat every floor as suspect until the meter tells us otherwise. Sixteen coating systems sit in our kit, and part of the free walk-through is being straight with you about which one your slab can actually carry.

How a Miami garage install actually runs.
Walk-through
Free and on site. Moisture meter, photos, and a straight scope. Same week across the city.
Prep day
Diamond grind to profile. Chase the cracks. Vacuum it clean. Re-check the moisture reading.
Coating day
Vapor primer if needed, then basecoat, flake broadcast, topcoat. Most bays finish in one day.
Cure and handoff
Walk on it at 24 hours, park on it at 48. We stop back at 30 days to look it over.
Other floors we pour in this city.
Sixteen systems total. The slab and the way you use the room decide which one goes down, and we will point you at a different one if it will outlast this. Photos of finished work are in the project gallery.
What Miami homeowners ask us first.
Why did my big-box garage kit peel off with the tires?
That is hot-tire pickup, and it is the most common failure we see in Florida. A thin coating over an acid-etched slab never bonds deeply, and hot tires on a summer afternoon soften it enough to lift it when you pull out. Diamond grinding plus a full-build system is the fix, and it is why we will not sell a single-coat product here.
Does an old Miami slab really need moisture testing?
Yes. A lot of these garages were poured before a vapor barrier under the slab was standard, so groundwater pushes up through the concrete year-round. We run a calcium-chloride or relative-humidity reading before we spec anything and add a vapor-barrier primer when the numbers call for it. Coating a wet slab is how a floor blisters in its first season.
Can you coat a carport or a garage that is open on one side?
We do it often in Coconut Grove and Little Havana. Open slabs need extra care at the perimeter, since wind-driven rain hits the edges first and that is where a weak coating starts letting go. We seal the edges properly and pick a topcoat rated for that exposure.
Will the floor hold up if the garage is really storage?
It will, and honestly that is what most of these floors do during storm season. A flake finish hides scuffing from dragged bins and furniture, and the sealed surface means fuel, oil or a knocked-over paint can wipes up instead of soaking in. Tell us how you use the space and we will match the topcoat to it.
