Old coating peeling, sealer worn thin or a new floor planned? We grind, test and prep the slab so the next coat holds.
Concrete grinding and surface preparation in Country Walk takes the worn, dirty or coated top of your slab down to clean, sound concrete, so the sealer, coating or overlay you put on next bonds to the floor instead of peeling off it.
Most calls start with something you can see, like paint flaking off a garage floor near the door, a patio coating lifting at the edges or a shop floor nobody's touched in years. What's on top is usually only half the story, because a coating fails from underneath when the slab was dirty, sealed, damp or too smooth for it to grab. Grinding is how we get past all that to concrete a new finish can hold onto.
The price mostly moves with the size of the floor, what's on it now and how much cracking or damage the grinding turns up, since thick old epoxy or glue takes more passes than bare concrete. The schedule turns on the slab itself, because we don't set a coating date until the floor tests ready. After I've looked at your floor and tested it, the written estimate gives you your own number.
Here's how it goes from the first call to the finished floor, and who you'll be dealing with at each step. It starts with a call to (786) 733-0104 or the form below.
When you call, I set up a time to come out, look at your floor and test the slab, the same work I've done on every job since I opened the business in 2017. You get a written estimate that lays out the prep your slab needs and the system we'd put down.
We check which office covers your address before we schedule anything. If your job needs a permit or other approval, we handle the application and tell you what you need to sign.
We're fully licensed and insured, and our crew does the work with me on the floor alongside them. When the job's done, we walk the finished floor with you. Your satisfaction, guaranteed.
Prep decides whether a coating lasts, so we take our time on it. Before the grinder comes out, we check the slab against the coating maker's moisture limits instead of guessing by the date it was poured. Then we grind off whatever's on top, whether that's old paint, sealer, glue or the weak skin of the concrete, until we're down to sound, open concrete, and we fix what the grinding uncovers before anything new goes on. I'd rather tell you a slab isn't ready than coat it and hope.
Prep is the first half of a bigger job. If all your slab needs afterward is protection from stains and wear, we move straight on to concrete sealing. If grinding shows a floor that's pitted, worn or patched past what a coating can hide, concrete resurfacing and overlays give you a new top surface to build on.
Every slab's a little different, but the order doesn't change, because each step depends on the one before it.
We test first, because if the slab's holding too much moisture, no amount of grinding keeps a coating stuck to it. If it isn't ready, I'll tell you so, and we'll set the date once it is.
We close off the room or deck and keep people out while the grinder's running. Then we work across the floor in passes until the old finish is gone and the surface is open and rough enough to grip.
Grinding often opens up cracks, chips and soft spots that were hiding under the old finish, so we fill and patch those next. Then we vacuum the floor down so no dust ends up trapped under the new coat.
We go over the whole floor one more time to make sure it's clean, sound and ready for the system you picked. Only then does the sealer, coating or overlay go down.
Tell us the size of the floor, what's on it now and whether you're planning a sealer, coating or overlay, or call (786) 733-0104. We reply within one business day to set up a time for me to come out and test the slab. The estimate is free, done on site and comes with no obligation.
(786) 733-0104Surface prep matters because poor prep is one of the main causes of coating failure, and it's settled before the first coat ever goes on. Grinding readies the surface for sealers, coatings, overlays and concrete repair, so whatever goes down next is only as good as the floor under it. Any floor looks good on the first day, and the prep decides how it holds up after that.
You know by testing the slab and comparing the result to the coating maker's limits, because there's no reliable fixed drying time. How fast a slab dries depends on the concrete mix, how thick it is, how it was cured and what's around it, and too much moisture is a leading cause of blistering, bubbling and peeling. A plastic sheet taped to the floor or an electronic meter only screens for a problem, so for a measured result you can ask for an in-slab relative humidity test or the calcium chloride test most specs cite. The pass or fail line comes from the maker of the coating you choose, and there's no one number that fits every product.
You can look a contractor up on Miami-Dade County's online contractor search, which lists contractors holding a county Certificate of Competency along with their status and any complaints. It also helps to know the two kinds of Florida license, because a state certified license allows work anywhere in Florida while a registered license only covers the cities or counties where the contractor holds a certificate of competency. Ask which one a contractor holds before anyone starts grinding your floor.
Grinding makes fine silica dust, and OSHA's silica standard requires construction employers to limit how much of it their workers breathe. Employers either follow the control methods the standard lists or measure the exposure and choose their own controls, and covered employers keep a written plan that includes keeping people away from areas where exposure may run high. It's fair to ask any crew how they'll limit access during your job, and with us that's the closed-off work area described above.
We're based in Country Walk and work across the cities around it in Miami-Dade County, including Kendall, The Hammocks and Richmond West, and most of what we prep there is garages, patios, pool decks and the occasional shop or warehouse floor. In unincorporated Miami-Dade, the county requires an impervious surface permit for a stand-alone surface improvement, but its list names slab and driveway replacement, not grinding, so it doesn't settle whether a prep job like yours needs one. That's why we check your address first, and Miami-Dade County is the place to ask if you'd like to hear it from them.
Licensing is the other thing worth checking here. The county's Contractor Licensing Section licenses contractors who work in Miami-Dade, and its Concrete Finish Contractor certification is the one that covers surface treatment of hardened concrete, which is what grinding and prep are. Before you hire anyone for this work, ask what license they hold and look them up the way the license question above describes.
Call (786) 733-0104 or use the form, and you'll know whether your floor is ready before you've spent money on a coating for it.
If you're not sure what's on your floor or whether it's ready for a coating, give us a call and we'll talk it through.
