Concrete Prep, Polishing & Repair in Greenville, SC
A lot of people call us about epoxy flooring and find out the real conversation is about their concrete first.
That's not a bad thing — it's just honest. The coating is only as good as what's underneath it. And in a lot of cases, the concrete itself needs attention before anything else happens.
We've walked into garages in Simpsonville where the slab looked fine from the door but had hairline cracks running the length of the floor once you got close. We've seen basements in older Five Forks homes where decades of moisture had pushed up through the slab and destroyed two previous coating attempts. And we've quoted warehouse floors in the Greer corridor where the concrete had been so beaten down by forklift traffic that the surface was basically powdering underfoot.
In every one of those cases, the fix started with the concrete — not the coating.
This page covers the concrete-side services we provide: surface prep, crack and spall repair, staining, driveway protection, leveling work, and coatings built for industrial and chemical-heavy environments.
Concrete Services We Offer
Concrete Surface Grinding & Prep
Surface preparation is the most important step in any floor coating project. It's also the step that low-bid contractors skip, and it's exactly why so many epoxy floors fail within a year or two.
Concrete is porous. For a coating to bond properly and stay bonded, the surface has to be mechanically opened — meaning the top layer of concrete needs to be ground down to expose a clean, profiled surface that the coating can grip.
Acid washing used to be the standard method. It's not anymore, and for good reason. Acid etching is inconsistent, leaves residue that interferes with adhesion, and does nothing about surface contamination from oil, grease, or previous coatings. It's a shortcut that costs you in the long run.
We use diamond grinding on every project. Industrial-grade grinding machines with diamond-segmented tooling cut a consistent surface profile across the entire slab — one that's clean, open, and ready to bond.
What the prep process includes:
- Diamond grinding to the appropriate CSP (Concrete Surface Profile) for the specified coating system
- Oil and grease decontamination in areas with prior vehicle or equipment use
- Removal of existing coatings or sealers that would interfere with adhesion
- Moisture testing before coating application
- Dust containment during the grinding process
We don't cut corners on prep. If the grinding takes longer because the concrete is hard or the surface is particularly contaminated, we take the time. Rushing this step is how you end up with a beautiful-looking floor that starts peeling in six months.
Concrete Crack & Spall Repair
Cracks in concrete are common. Most of them aren't structural emergencies — but some of them are, and it matters to know the difference before you coat over anything.
Shrinkage cracks are the fine, hairline cracks that show up as concrete dries and settles. They're largely cosmetic and don't affect structural integrity. We fill these with a semi-rigid polyurea filler that moves with the slab without re-cracking.
Control joint cracks form at the intentional saw cuts in the slab. These are designed to crack at a predictable location. They need to be filled but treated differently — a rigid filler here will just crack again because the joint is still moving.
Active cracks — cracks showing signs of ongoing movement, widening, or vertical displacement — are a different situation. Coating over an active crack without addressing the cause is a short-term fix that will fail. We'll tell you if that's what we're looking at and what the options are.
Spalling — where the surface of the concrete has flaked, chipped, or broken away — is common in older slabs and in areas with heavy freeze-thaw history or deicing salt exposure. We repair spalled areas with a cementitious patching compound or epoxy mortar depending on the depth and location of the damage.
All crack and spall repair work is done before any coating goes down. We document the repairs during the estimate so you know exactly what's being addressed and why.
Interior Concrete Staining
Stained concrete sits in a different category than epoxy flooring. It's not a coating that sits on top of the concrete — it's a chemical or water-based colorant that penetrates into the surface and bonds with the material itself.
The result is a floor with color that can't peel or delaminate, because it's part of the concrete rather than a layer on top of it.
Acid staining uses a diluted acid solution with metalite salts to react with the calcium in the concrete. The reaction creates natural, mottled color variation — earthy tones in amber, brown, and terra cotta that look almost like natural stone. No two acid-stained floors look the same, which is part of the appeal.
Water-based concrete stains offer a wider color range and more predictable results. The color is more consistent and controllable than acid staining, which makes it a better fit when you need a specific match or a more uniform appearance.
Both systems are sealed after application — typically with a polyurethane or epoxy sealer — to protect the color and make the surface easy to maintain.
Interior concrete staining is a good fit for:
- Finished basements being converted to living space
- Home gyms and studios where a natural material look is preferred
- Retail and commercial spaces going for an industrial-modern aesthetic
- New construction where the concrete slab is clean and in good condition
One honest note: staining works best on clean, uncontaminated concrete. Slabs with heavy oil staining, patched areas, or significant variation in age and mix will produce unpredictable results. We'll assess the slab during the estimate and tell you what to expect before you commit.
Concrete Driveway Sealing & Coating
Driveways take a lot of abuse — vehicle weight, oil drips, UV exposure, rain, and in the Upstate, enough summer heat to soften lower-quality sealers that aren't built for it.
An unprotected concrete driveway absorbs all of that. Oil and fluid stains soak in and become permanent. Water penetrates the surface, freezes in winter, and accelerates cracking. UV exposure causes the surface to scale and dust over time.
Sealing stops most of that. Coating takes it further.
Penetrating sealers absorb into the concrete and repel water and oil without changing the surface appearance. They're a good maintenance option for driveways in good condition that you want to protect going forward.
Acrylic and epoxy-based surface sealers sit on top of the concrete and provide a visible protective layer. They add a wet look or low-sheen finish and make the surface easier to clean. These need to be reapplied more frequently but provide stronger stain resistance.
Full epoxy or polyaspartic driveway coatings are the most durable option. They're the same chemistry we use on garage floors — a mechanically prepped surface, a base coat, and a UV-stable topcoat. This is the right choice for a driveway where appearance matters and you want the longest service life with the least maintenance.
We also repair driveway cracks and surface spalling before sealing. Sealing over damage doesn't fix it — it just seals the damage in.
Self-Leveling Epoxy Underlayment
Some concrete slabs aren't flat. They have low spots, settlement dips, or surface irregularities that would show through a finished coating or cause pooling in areas where water needs to drain away.
Self-leveling epoxy underlayment fixes that.
It's a pourable epoxy compound with enough flow to seek out low spots and fill them, creating a flat, level surface that's then ready for a finish coat system. It can correct variations of up to a quarter inch or more depending on the product and pour depth.
Where this comes up most often:
- Older slabs that have settled unevenly over time
- Basements where the concrete was never poured particularly flat to begin with
- Commercial spaces where a level floor matters for equipment operation, racking systems, or safety
- Transitions between slab sections where one pour settled differently than another
Self-leveling underlayment is also used as a skim coat over concrete that has significant surface porosity or texture variation — situations where a standard base coat would consume too much product trying to fill surface irregularities.
We assess whether leveling work is needed during the estimate. It adds to the project scope and timeline, but it's worth getting right — a finish coat over an uneven slab is going to look uneven.
Industrial Grade Warehouse Coatings
Warehouse and industrial floors operate in a different environment than residential concrete. The demands are higher, the consequences of a coating failure are more disruptive, and the wrong system can become a real safety and operations problem.
We're familiar with the industrial demand in the Greer and GSP corridor — the manufacturing facilities, distribution operations, and commercial support businesses that cluster near the airport and BMW plant. These aren't garage floors.
They need to handle:
- Constant forklift and pallet jack traffic
- Heavy point loads from racking systems and equipment
- Chemical exposure from lubricants, cleaning agents, and process fluids
- Abrasion from foot traffic in steel-toed boots
- The need for defined traffic lanes, safety markings, and equipment zones
For these environments, we specify 100% solids industrial epoxy systems — typically two-coat or three-coat builds with a broadcast aggregate or non-slip additive for traction. Film thickness matters here. An industrial system needs to be built up to spec, not applied thin to save material cost.
We also handle safety line striping and floor marking as part of industrial projects — defined pedestrian lanes, equipment zones, hazard markings, and dock areas.
If you're managing a warehouse or industrial facility in the Upstate and your floor is showing wear, delamination, or surface breakdown, reach out for an on-site assessment. We can evaluate the existing surface and put together a system spec that fits your operations.
Chemical Resistant Shop Floors
Not every shop floor has to deal with industrial chemicals. But for auto repair shops, body shops, manufacturing facilities, laboratories, and commercial kitchens, the floor coating has to do more than just look good — it has to stand up to what gets spilled on it.
Standard epoxy is fairly chemical resistant, but "fairly" isn't good enough in environments where the floor is regularly exposed to motor oil, brake fluid, transmission fluid, strong degreasers, or industrial solvents.
For those environments, we specify chemical resistant epoxy or novolac epoxy systems. Novolac epoxy is a higher-performance resin that provides significantly better resistance to acids, bases, solvents, and hydrocarbons than standard epoxy chemistry.
Typical applications:
- Auto repair and body shops — resistance to oil, fuel, brake fluid, and the heavy-duty degreasers used for cleanup
- Commercial kitchens — resistance to cooking grease, food acids, and the caustic cleaning chemicals required by health codes
- Manufacturing and fabrication shops — resistance to cutting fluids, hydraulic oil, and process chemicals
- Laboratories and pharmaceutical environments — resistance to a broad range of reagents and cleaning agents
We assess the specific chemical exposure for each project before specifying a system. What works for a general auto shop isn't necessarily the right call for a surface that sees concentrated acids or strong solvents. Getting the chemistry right upfront is a lot cheaper than replacing a floor that failed because the wrong system was installed.
The Right Foundation Makes Everything Else Work
Every coating system we install — whether it's a residential flake floor in a Five Forks garage or an industrial warehouse coating in Greer — starts with the concrete.
That means proper surface preparation. That means addressing cracks, spalling, and moisture before anything gets applied. And that means being honest with you during the estimate about what the concrete needs, even when it adds to the scope.
We've seen what happens when those steps get skipped. We'd rather have the straightforward conversation upfront than get a call six months later about a floor that's failing.

Frequently Asked Questions
How do I know if my concrete needs grinding before coating?
Almost always, yes. Diamond grinding is the standard for any professional floor coating installation. The only exception might be a very light penetrating sealer on clean concrete in good condition. If you're getting an epoxy or polyaspartic system installed, the concrete needs to be mechanically prepped. Any contractor who says otherwise is cutting corners.
Can you coat concrete that has oil stains from vehicles?
Yes, but the contamination has to be treated first. Oil soaks into concrete and will prevent coating adhesion if it's not addressed. We use commercial-grade degreasers and grinding to remove as much contamination as possible. In severe cases — think a floor that's had oil dripping on it for 20 years — we may need to apply a specialized primer designed to seal in residual contamination. We assess this during the estimate.
My driveway has cracks. Should I seal it or repair it first?
Repair first, then seal. Applying sealer over active cracks just traps moisture inside them. We fill cracks before any sealer or coating goes down. If the cracks are showing significant movement or settlement, we'll let you know and discuss whether a more involved repair is needed.
What causes concrete to spall?
Spalling — where the surface layer chips or flakes away — usually comes from one of three things: freeze-thaw cycles forcing moisture to expand inside the surface, rebar corrosion expanding below the surface, or deicing salts accelerating surface breakdown. In Upstate SC, we see it most often from moisture infiltration over time or from prior surface prep issues in older slabs.
How flat does concrete need to be for a coating to look good?
Reasonably flat. Minor texture and slight variation in the concrete surface will be filled by the coating system in most cases. Significant dips, humps, or settlement — more than about an eighth of an inch across a span — will show through the finished surface and may require leveling work first. We'll flag this during the estimate if it's an issue.
Can interior concrete staining be done in a basement that gets damp?
Damp basements need to be evaluated carefully before any flooring work. Moisture migrating up through the slab will cause adhesion failure in coatings and can push up stain sealers over time. We moisture test all slabs before specifying a system. In basements with active moisture, an epoxy vapor barrier may be needed before the finish coat or stain goes down.
How long do industrial floor coatings last in a warehouse environment?
It depends heavily on traffic volume and type. A properly installed industrial epoxy system in a moderate-use warehouse can last 10 years or more with basic maintenance. High-traffic areas near dock doors and heavy equipment zones will show wear faster. We can spec systems with sacrificial top coats that can be reapplied without stripping the full system — essentially a maintenance-mode approach that extends the total floor life.
Do chemical resistant coatings require special maintenance?
Not significantly. Regular sweeping and mopping with a neutral cleaner handles most situations. The main thing to avoid is letting highly concentrated chemicals pool and sit on the surface for extended periods — even chemical resistant coatings have limits. Prompt cleanup of spills is the best maintenance practice in any chemical-heavy environment.
