McKinney Garage Floor Coatings
McKinney sits on some of the most active clay soil in Collin County, and garage slabs here move with it season to season. Sherwoods Eternal Foundation preps for that movement before a drop of resin goes down, then finishes with flake and polyaspartic systems that stay put through August heat and February cold snaps.
Coating a McKinney Garage Slab
McKinney is really two towns as far as concrete goes. Around the historic square and the older streets east of US-75, we work on slabs poured decades ago that have already settled, cracked, and been patched by somebody. Out at Trinity Falls and the newer sections off US-380, the concrete is barely broken in and still giving off curing moisture. Cody reads the slab before he prices anything, because those two jobs need different amounts of work up front.
Either way the prep is mechanical. We diamond-grind the whole floor down to open concrete so the resin has something to bite into. Cracks get chased out and filled, control joints get treated so they do not print through the finish a year later, and we run a moisture check on newer pours before committing to a base coat. Skip any of that and the floor looks great for a season, then starts lifting at the garage door where the sun hits it.
The build itself is a hundred-percent-solids epoxy base, vinyl flake broadcast to full refusal, and a polyaspartic topcoat carrying aluminum-oxide grit so the floor is not slick when somebody tracks in rain off the driveway. Finished thickness lands around twenty-five to thirty mils. That is a real floor, not a rolled-on kit from a box store, and it takes jack stands, dropped sockets, and a rolling toolbox without complaining.
Clay Soil, Cracks, and Honest Answers
Collin County clay swells when it rains and shrinks when it does not, and a McKinney garage slab rides on top of all that. Most of what we see is hairline shrinkage cracking, which we grind, fill, and coat over without a second thought. Where a crack is wider or shows a lip between sides, we say so and treat it with a flexible repair and a crack-isolation detail so the coating has room to move.
What we will not do is coat over a structural problem and let you find out about it later. If a slab has heaved badly enough that a coating would be lipstick on a real issue, Cody tells you that on the walkthrough instead of taking the job. That is one of the reasons people in Stonebridge Ranch and Craig Ranch keep sending neighbors our way.
Why McKinney Homeowners Call SEF Epoxy
This is not a franchise van with a rotating crew. Cody spent ten years pouring live-edge resin tables before he ever coated a garage, and that background shows up as patience on the grinder and stubbornness about product compatibility. He would rather turn down a job than rush a slab that needs another day of prep.
It also means the person who prices your floor is the person who grinds it and the person you call afterward. Nothing gets subbed out to whoever is available that week. If something about the finish is not right, there is one phone number and one name attached to it, which is a short list compared to most of what gets advertised around Collin County.
How the Day Runs in McKinney
A standard two-car McKinney garage is one full day on site. Three-car and tandem bays, which are common out toward Adriatica Village and the newer builds, run a day to a day and a half depending on how much crack work the slab needs. You walk on it after twenty-four hours and park on it after seventy-two.
Those cure windows matter more here than people expect. A car coming off US-75 in August rolls in with tires still hot and soft, and that is exactly the condition that lifts a coating parked on too early. Give the polyaspartic its full three days and it shrugs off hot tire pickup for the life of the floor. Cody would rather you wait the extra day than call him about tire scars in October.
On the hottest stretches we start early, while the slab is still cool enough for the product to lay out flat. Before he packs up, Cody walks you through what to avoid for the first month. Questions after that get answered through our contact page or the shop phone.

McKinney Garage Floor Coatings FAQ
My McKinney slab has cracks. Can it still be coated?
Almost always, yes. Shrinkage cracks and old control joints are routine work here. We chase them open, fill them, and detail the joints so they do not telegraph through the flake. If a crack shows real vertical displacement, Cody flags it on the walkthrough and explains what it means before anything gets scheduled.
Is a brand new Trinity Falls slab ready for coating?
Usually the surface is clean and easy to work, which speeds up grinding. The thing to watch is curing moisture, since fresh concrete can still be giving off water that will blister a base coat. We run a moisture check on newer pours and schedule accordingly instead of guessing.
Will the finish hold up to a west-facing McKinney garage?
Yes. The polyaspartic topcoat is UV stable, so it does not amber the way a plain epoxy topcoat will when afternoon sun comes straight through an open door. It also stays hard at the temperatures a McKinney garage hits in August, which is what keeps hot tires from marking it.
Can I pick a color that matches the house?
Bring a photo or a paint chip. We carry a wide range of flake blends and pull sample boards out on every walkthrough, so you see the actual chips in your own garage light before anything is ordered. Plenty of McKinney folks go neutral for resale, and plenty go bold because the garage is a workshop.
What separates this from the one-day crews advertising around McKinney?
Prep time and cure time. A volume crew is built to grind fast, coat fast, and be gone by dinner so they can hit another house tomorrow. Cody came out of ten years of resin craft work and holds the full cure schedule every time. That is the difference between a floor that still looks right in year five and one that peels in year two.
