Does my concrete need grinding before a new floor goes down?
Concrete grinding and surface preparation in College Station is the step that cuts the top of your slab, takes off old coatings and leaves the roughness, called surface profile, that a new coating needs to grip.
Most people call us because a garage floor is peeling, a shop slab is wearing years of old paint, or they want a garage floor coating and someone told them the concrete has to be ground first. They're right. The price moves with the size of the floor, how many old layers have to come off, how much crack and joint repair the slab needs and how rough the next coating wants it. The schedule turns mostly on what the moisture test shows and what's hiding under the last coat, since concrete rarely tells you everything at a glance. I'll look at the floor and send you a written estimate that lists the prep along with the finish, so you can see what's going under the coating and what it costs.
How we handle concrete grinding and surface preparation
Before grinding starts, we check the slab for moisture, since there's no sense profiling a floor the coating won't stay on. Then our crew grinds with diamond tooling, works the edges, corners and around posts so the whole floor gets the same prep, and takes old coatings off fully instead of skimming the top layer and calling it done. We set how rough we leave the surface by the coating going on next, and we clean the slab before that coating goes down.
Grinding is the first half of most floors we do. When you'd rather keep the ground slab bare, concrete sealing protects it, and when the surface turns out too worn or damaged to coat as it is, concrete resurfacing and overlays give us a sound new top to build on.
A rougher profile for thick systems
Thick coatings like a full epoxy or urethane cement system need a surface with real tooth, because on concrete that's too smooth they have nothing to bite into. This suits garages and shops getting a heavy coating.
A finer grind for thin coats and sealers
A thin coat or a sealer shows every scratch a coarse grind leaves, so we stop at a smoother finish that still gives it something to bond to. It suits floors that will stay close to bare concrete.
Concrete grinding and surface preparation on College Station slabs
The City of College Station asks for a building permit before work starts on new structures, remodels and renovations, and its list names those, not concrete grinding, so whether your job needs one isn't settled on paper. Before anything gets scheduled, we check with the city's building permit office and take care of the permit when it falls to us, and we'll tell you what we found out. The city also requires a contractor to register before pulling a building permit, while a homeowner can get one without registering for work on a house they own and live in as their homestead.
A lot of Texas sits on expansive clay that swells when it's wet and shrinks when it dries, which is one reason slabs here show hairline cracks and busy joints by the time we see them. Concrete is going to crack, and control joints, the cut lines in the slab, tell it where. We fill static cracks with a rigid material and give moving control and expansion joints a flexible sealant, because a coating laid solid over a joint that moves will crack right along that line. We're based in College Station and see the same slabs on jobs in Bryan, Navasota and the cities around them.

I come out for every estimate
I do the estimates and first visits myself, and our crew handles the grinding, prep and coating with a lead installer on site. The person who looked at your slab is the one answering for it.
Prep-first floors since 2020
I learned coating work on an experienced installer's crew and started this business in 2020, after years of pressure washing garages and patios. We're best known for garage floors and careful prep, because the work under the coating is where floors fail.
Licensed and insured on every job
We're licensed and insured, so you aren't the one carrying the risk while heavy grinders run in your garage or shop. That's worth confirming with anyone you let work on your floor.
Straight talk about your slab
On a slab that's moved on Texas clay or held onto years of old coatings, I'll tell you plainly what it can carry. I'd rather talk you out of a job than put down a floor I don't think your slab will hold.
Most of what decides whether a new floor lasts happens before the coating goes on. Reach us through the contact page and I'll come take a look at your slab.

Frequently asked questions
Do I need grinding to remove an old coating from my concrete?
Yes, if the slab has been coated before or is heavily contaminated, grinding is what gets the old layers fully off. A new coating is only as good as what it's stuck to, so if there's paint or epoxy on your floor now, plan on grinding being part of the job.
Is grind and seal the same as polished concrete?
No, grind and seal is a lighter process that skips the full polishing sequence, so you end up with a different floor than a fully polished slab. It can make sense for a back room, a storage area or a tight budget. When you compare quotes, compare what each one includes, not just the bottom line.
Why does concrete need a moisture test before grinding?
Moisture is what one field guide calls the number one cause of resin floor failure, and it says to test before prep rather than after the coating starts to bubble. On a slab getting a resin coating like epoxy, the test comes before any grinding. Bad news is a lot cheaper to hear then than after the floor is down.
How long does it take to prep a concrete floor for a new coating?
The schedule usually turns on the moisture test more than the grinding, because the test has to come first. One moisture meter maker's guide says the testing standard wants the slab and the air above it at the conditions the room normally runs at for at least 48 hours before testing, so ask us when that window should start. After that, the number of old layers and the amount of crack and joint work set the pace.
How much does concrete polishing cost in College Station?
Polishing concrete across the US usually costs about $8 to $9 per square foot, and that's the going rate for a polished floor, not our price. Grinding a slab to take a coating is a different job, so for that you'll get a figure from our estimate on your floor.
How do I take care of a polished concrete floor?
Clean it regularly with a neutral cleaner, and plan on an occasional guard reapplication or re-burnishing, a high-speed buff, in the areas people walk most. Polished concrete is the slab itself, so there's no film to peel. Our work is backed by our satisfaction guarantee.
Work that often goes with concrete grinding
Concrete Sealing
When you'd rather keep bare concrete than coat it, a sealer helps the ground slab hold up to spills, water and everyday traffic in a garage, patio or storage room.
Concrete Resurfacing & Overlays
When grinding shows a surface that's too pitted, flaking or uneven to coat as it is, a resurfacing overlay gives your slab a fresh, sound top to build the new floor on.
