Garage floors, polished concrete and commercial coatings, installed on a slab we have tested first.
College Station Epoxy Flooring has spent more than 20 years putting resinous coatings and polished concrete down on slabs in College Station, Texas, and the surrounding Brazos Valley. We install epoxy garage floors, polished concrete, polyaspartic and polyurea systems, flake and metallic finishes, pool deck resurfacing, concrete resurfacing and commercial floors for kitchens, clinics, shops and rental property.
What separates a coating that lasts from one that peels in sheets is almost never the product on the label. It is what the crew found out about the slab before the first pail was opened, and whether they were honest about it. We test rather than assume, and we put the findings in the proposal where you can read them.
That matters more here than most places, because the ground under this city is not what people assume it is. College Station sits on Texas Claypan soils, and the practical problem on a Brazos Valley slab is usually moisture rather than movement. Getting that the wrong way round is how a floor fails in its first year.

More than 20 years of installing and repairing coated floors in this market means we have already seen how the local slabs fail, which products hold on them, and which shortcuts show up three summers later.
Texas licenses no flooring contractor at all, so a license number would be meaningless here. We show general liability cover, workers compensation, a Texas sales and use tax permit and our city contractor registration, all of which can be checked.
Every proposal names the product, the system build and the mil thickness, so what was quoted can be measured against what was installed once the floor is down.
Most of this city is a thin sandy cap lying over stiff clay, and that cap can be anywhere from 2 to 18 inches deep. We establish which it is before quoting, so the specification matches the ground rather than a regional stereotype about Texas clay.
No slab we did not pour ourselves gets coated without a moisture reading, using ASTM F1869 calcium chloride tests and ASTM F2170 relative humidity probes. It is priced into the job rather than sold as an extra after a floor blisters.
Every slab is diamond ground or shot blasted to a measured ICRI CSP profile. We do not acid etch and we do not coat over an existing sealer, because a coating bonded to a sealer is only as good as whatever that sealer is holding.
We work to the dew point at the slab surface rather than the air temperature, which is why summer starts here are mid-morning. Concrete lags the air, and a slab at or below dew point takes a coating that fails from underneath.
A coating is a film. It follows the slab, and it will not bridge or resist ground movement, so we say that before the job rather than in a warranty exclusion afterward.
The work runs from an initial slab assessment and moisture test, through mechanical profiling, crack and joint treatment, primer, build coat and topcoat, to a cure period before vehicles return. Knowing the sequence up front tells you which days you lose the garage and which you do not. Most residential garages run two working days on site plus cure time, though a slab needing moisture mitigation or significant repair adds a day before any color goes down.
The ground is not the same from one side of College Station to the other, and neither is the right specification. We identify the soil series and the depth to the clay horizon under your slab so the moisture strategy is chosen from evidence rather than from a guess. Boonville, Zack, Sandow, Burlewash and Singleton are the series that cover most of the city, and they do not all behave the same way under a slab.
Diamond grinding and shot blasting open the concrete’s pore structure to a measured surface profile so the primer can key into it. A coating laid over troweled, sealed or power-floated concrete is bonded to the surface skin, and that skin is what lets go.
A settled crack has stopped moving and can be filled rigid and coated over. A live crack has not, and treating one as the other guarantees a telegraphed line through the new floor. We assess each on the slab rather than treating every crack the same way.
Where a crack sits over ground that still moves, we treat it as a working joint with a semi-rigid polyurea filler rather than filling it solid and coating across it. We also tell you before the job that it may telegraph again, because a filler follows the slab like everything else.
The slab has to be completely empty, and in most garages that is the part nobody has planned for. We agree in advance who moves what and where it goes, so the crew is not waiting on a shelving unit on the morning of the grind.
The places a garage floor stops are where a cheap job shows first. We detail the threshold, the step-down into the house and the slab edges deliberately, so the coating terminates in a clean line rather than a feathered edge that chips.
A 100 percent solids epoxy body coat with a polyaspartic or polyurea topcoat is the common answer for a garage that sees a Texas summer, because the topcoat carries the ultraviolet stability and the abrasion resistance. Straight epoxy is cheaper and ambers; the right pick depends on light and use.
Foot traffic and vehicle traffic are two different cure milestones, and vehicles are the later one by a wide margin. Hot tire pickup happens when a floor is loaded before the coating has cured through, so we give both dates and hold to them.
College Station sits in the Texas Claypan, not the Blackland Prairie that dominates the reputation of Central Texas soils. Area-weighted inside the city, Vertisols account for a fraction of a percent of the ground, which is a fundamentally different problem from a true shrink-swell market and calls for a different specification. Contractors who work both markets tend to carry one mental model between them, and it is the wrong one roughly half the time.
The typical profile here is an inert fine sandy loam cap with a plasticity index near 4, sitting abruptly on a smectitic clay horizon running a plasticity index of roughly 27 to 41. The cap is 2 to 18 inches thick, and that depth is the single number that changes what your slab is doing. Where the cap is deep, the slab is largely bearing on inert material; where it is thin, the reactive horizon is close enough to matter.
The clay horizon is very slow to drain, so through winter and spring water sits on top of it rather than moving down through it. That perched water is a reservoir directly beneath the slab, and it drives vapor upward into any coating that is not specified for it. It is also seasonal, which is why a floor can go down clean in September and blister the following March.
On most College Station slabs the first question is how much water vapor is coming up through the concrete, and the second is whether the ground is moving. In a true Blackland Prairie market that order reverses, which is exactly why a specification imported from elsewhere in Texas fails here.
An ASTM D4263 plastic sheet taped to the slab overnight tells you almost nothing. Calcium chloride testing under ASTM F1869 and in-situ relative humidity probes under ASTM F2170 give numbers you can hold a product’s ASTM F710 thresholds against, and those numbers decide whether a moisture-mitigation primer is required. The probes read the slab’s internal humidity at depth rather than its surface, which is the measurement that actually predicts what a coating will face over its life.
Osmotic blistering, pinholes and a coating that lifts in sheets are usually one story: vapor pressure from below exceeded the coating’s tolerance. We take a moisture reading under a failed floor before quoting the repair, because recoating over the same conditions buys a repeat.
The city’s own minimum foundation standard calls for a 6 mil polyethylene vapor retarder beneath the slab, and it also caps fill material at a plasticity index between 5 and 18. A slab poured to that standard starts from a very different place than an older one with nothing under it. Worth knowing too that the local claypan subsoil itself runs well above that fill limit, so the material under a slab is not necessarily the material the standard contemplates.
The two cities do not share a housing age. Owner-occupied stock built before 1980 runs about 13 percent in College Station against about 36 percent in Bryan, with median build years of 1999 and 1991, so a Bryan garage is far more likely to be a pre-vapor-retarder slab.
The minimum foundation standard puts the exterior beam at 30 inches deep, which is below the sandy cap almost everywhere in the city. That leaves the perimeter bearing in reactive clay while the interior bears on inert sand, which produces differential rather than uniform movement. Uniform movement lifts a slab evenly and is comparatively benign; differential movement is what cracks one, and it is the pattern this geology tends to produce.
Where a lot was cut and scraped before the slab was poured, the sandy cap may be largely gone and the clay may start within a couple of inches of the underside. The eroded phases of local series are exactly that, and it is why two houses on one street can need different answers.
Through the summer we start mid-morning rather than at first light, and it is not a staffing preference. The slab is coldest and the air is most humid at dawn, which is precisely when a coating should not be going down.
The working rule across manufacturer data sheets is that the surface must be at least 5 degrees above the dew point, measured at the slab rather than in the air. Concrete lags air temperature, so an air reading that looks fine can sit over a slab that does not. We measure the slab surface directly rather than inferring it, because the inference is wrong precisely on the mornings it matters most.
On summer mornings here the gap between air temperature and dew point closes to a handful of degrees, and it does so on the large majority of them. A slab in that condition carries condensed moisture that is invisible and will still destroy adhesion.
The dew point margin typically clears late in the morning, and the afternoon heat arrives not long after. That leaves a genuine working window rather than an open day, and it is why an installer who shows up at 7:00 a.m. and leaves at noon is not doing you a favor. The same squeeze is why we would rather split a large floor across two mornings than rush a single coat through conditions at both ends of it.
Pot life falls sharply with temperature. Published manufacturer figures show working time dropping from around 2 hours at 50 degrees to about 1 hour at 75 degrees and to roughly 30 minutes at 100 degrees, so a hot slab in July changes batch sizes and crew sequencing.
The second coat has both a minimum and a maximum window, and the maximum is the one that catches people. Miss it and manufacturers require the surface be abraded before topcoating, which turns a straightforward second coat into another mechanical operation.
College Station averages roughly 16 freezing nights a year, which is mild, and that is not the scheduling problem. The problem is the occasional multi-day hard freeze, and this region has had several in recent winters.
Cure slows dramatically as temperature drops, and cure milestones stretch with it. We would rather move a start date than lay a floor into a falling forecast and hand you a coating that never reaches its specified hardness.
Epoxy curing in high humidity can develop amine blush, a greasy surface film that ruins the bond of anything laid over it. It is preventable with the right product selection and timing, and it is removable, but only if somebody recognizes it before the next coat.
Texas adopts the FDA Food Code through the Texas Food Establishment Rules, and the floor requirements live in the Food Code rather than in the state’s wall and ceiling section. Section 6-101.11(A) is the one that matters: smooth, durable, easily cleanable, and nonabsorbent where the floor gets wet. Citing the state’s wall and ceiling coatings section for a floor requirement is a common error, and it is the wrong section.
An integral coved base carries the floor up the wall in one continuous surface so there is no seam at the junction to trap soil. The Food Code sets the coved junction tolerance tightly, and a coving detail that does not meet it is a write-up waiting to happen.
A floor required to be smooth and easily cleanable seems to rule out a textured, slip-resistant surface, and most contractors either ignore the tension or talk around it. The Food Code answers it directly, carving out antislip floor coverings and applications used for safety reasons.
Constant washdown, disinfectants and standing moisture are harder on a floor than traffic is. Urethane cement and appropriately specified resinous systems with coved bases handle that duty, where a general purpose garage build simply will not.
Hot tires soften and lift a coating that is underspecified or was loaded before full cure, and it is the classic failure in a shop bay. The answer is a system built for it and a cure schedule that is actually respected.
Large floors live or die on joint treatment and on how traffic patterns are handled. Semi-rigid joint fillers support the joint edges under wheel loads, which is what stops the spalling that turns a joint into a maintenance line item.
Before a renovation disturbs suspect material in a commercial building, Texas rules require the building owner to have an asbestos survey performed. Old floor tile and the black cutback mastic under it are exactly what that is about, and we raise it before a grinder goes anywhere near the slab.
Turnover work here runs against a lease calendar rather than a contractor’s calendar, and the handover date is effectively part of the specification. We build the schedule backward from it, choosing systems whose cure times fit the window rather than promising a build that does not. A fast-cure polyaspartic system exists precisely for this, and it is the honest answer when the window is genuinely tight rather than a way to charge more.
Small rental buildings take heavy wear and get re-let quickly, so durability and fast return to service outrank appearance. Note also that the asbestos survey duty draws its line at buildings of more than four dwelling units, which is a real distinction for a duplex or fourplex owner.
College Station Epoxy Flooring provides epoxy flooring throughout the greater College Station area, with the same crews and the same standards on every job.
Good to know
Price is driven by slab condition far more than by square footage. A sound slab needing only profiling and a standard flake build sits at the lower end, while a slab requiring moisture mitigation, crack and joint treatment or removal of a previous coating costs materially more. We quote after testing rather than before, so the number does not move once work starts.
Texas does not license flooring, coatings or painting contractors, so nobody in this trade holds a state license and any company claiming one is describing something else. What we do hold, and what you can verify, is general liability cover, workers compensation, a Texas sales and use tax permit and our city contractor registration.
Most residential garages are two working days on site, plus cure time before the floor is used. Foot traffic and vehicle traffic are separate milestones and vehicles are considerably later. A slab needing moisture mitigation or substantial repair adds a day before any color goes down.
Because on this ground it is the most common cause of coating failure and it is invisible. Water perches on the clay horizon beneath much of the city through winter and spring and pushes vapor up through the concrete. We test with calcium chloride and relative humidity probes so the system is chosen against a number rather than an assumption.
No, and any contractor who says otherwise is making a claim they cannot support. A coating is a film that follows the slab underneath it. It will not bridge or resist ground movement, and where a crack is still working we treat it as a joint and tell you it may telegraph again.
Sometimes, but not on faith. An existing coating has to be assessed for what it is, how well it is bonded and what is happening underneath it. Where a previous floor failed from moisture, recoating without addressing the cause simply buys a repeat, so we take a reading under a failed floor before quoting.
Epoxy is the body of the system, building thickness and bonding to the prepared concrete, but it ambers in sunlight and is less abrasion resistant. Polyaspartic and polyurea are topcoats that cure fast, hold color under ultraviolet light and take the wear. Most garages here are best served by an epoxy build with a polyaspartic top.
We grind or shot blast, always, to a measured surface profile. Acid etching does not produce a consistent profile and leaves residue that has to be neutralized and removed. A coating is only as good as its bond to the concrete, and the bond is made in the preparation.
Yes. Those floors are specified differently from a garage because they face constant washdown, disinfectants and a health inspection. That usually means a urethane cement or resinous system with an integral coved base detailed to the Food Code requirements Texas adopts.
Yes, and it is a large part of what we do here. Turnover work runs against a lease calendar, so the handover date is effectively part of the specification. We schedule backward from it and select systems whose cure times genuinely fit the window rather than promising a build that does not.
