Killeen Epoxy Flooring installs epoxy garage floors across Killeen, TX and the surrounding cities including Fort Hood, Harker Heights, Nolanville, Copperas Cove and Belton, and we have been doing it for more than 20 years. A garage floor is the job this trade is best known for and the one most often done badly, because almost all of the work that decides whether it lasts happens before the first pail is opened.
The ground under most of this city is San Saba clay — a smectitic Vertisol running roughly 50 percent clay with a plasticity index of 40 and a linear extensibility around 10 percent, which is a very high shrink-swell rating. That soil expands when it takes water and contracts when it dries, and a slab sitting on it moves through the year. An epoxy film is a few thousandths of an inch thick and bonded, so it follows the concrete exactly. Everything we specify starts from that fact rather than from a product catalog.
So we look at your slab first: what it is sitting on, whether it has been coated before, what its cracks are doing and how much moisture is coming up through it. Then we quote a system, a build and a finished mil thickness in writing, so what you were sold can be checked against what went down.
What an Epoxy Garage Floor Actually Is
A System, Not a Coat of Paint
A durable garage floor is a stack: mechanical preparation to an ICRI CSP profile, crack and joint detailing, a primer matched to the slab’s moisture condition, a build coat that carries the thickness, and a wear coat that takes the traffic. Each layer does a job the others cannot. A single-product floor rolled onto an unprepared slab is the version sold in a box, and it is the version that peels off with the first warm tire.
Mil Build, and Why the Number Matters
Mil build is finished thickness, and it is a property of the tool and the spread rate rather than of the resin in the pail. A notched squeegee at a stated coverage puts down a known thickness; a roller and an optimistic coverage claim do not. We name the build in the proposal because it is the single number that separates a floor specified to last from one priced to win, and it is checkable afterward.
Hot Tire Pickup, and What Prevents It
A tire comes off the road hot, sits on the floor and softens a thin or under-cured film, then lifts a patch of it when the car moves. It is the most common complaint on a cheap garage floor. Full-build 100 percent solids epoxy with a polyaspartic or polyurea wear coat has the film thickness and the cure chemistry to resist it, which a thin water-based product does not.

Reading Cracks Before Coating Over Them
A crack that has finished moving and one that opens every dry summer look the same on any given day. We read width, edge condition and pattern to tell them apart. A settled crack can be filled rigid and closed permanently. A working crack gets routed and filled with a semi-rigid polyurea joint filler and carried through the coating as a joint, and we tell you before the job that it can telegraph again — because over this ground it can.
Moisture Testing an Older Slab
Moisture vapor driving up through concrete is the most common cause of epoxy adhesion failure on residential slabs, and under-slab vapor retarders were not standard practice on older Texas pours. We test rather than assume: calcium chloride to ASTM F1869 or in-situ relative humidity probes to ASTM F2170, read against ASTM F710 thresholds, with ASTM D4263 as a field check. A dry-looking floor is not a reading, and where vapor drive is high the answer is a moisture-mitigation primer specified up front.
Post-Tensioned Slabs and the Cables in Them
Post-tension slabs became common in Texas after about 1980, and roughly three quarters of this city’s housing was built in or after that year. Cutting, coring or driving an anchor into one risks severing a tendon, which turns a floor job into a structural repair. We establish slab type before anything penetrates the concrete, which on a stock this young is a live question on most jobs rather than a rare one.
Finishes, and What Each One Asks of You
Full Flake, Partial Flake and Solid Color
Vinyl flake broadcast to refusal gives the most forgiving surface: it hides dust, tire marks and minor slab irregularity, and the chip size and blend decide whether it reads busy or calm. A partial broadcast shows more of the base color. A solid color with a clear wear coat is the cleanest look and the least forgiving of a floor that gets used hard. We show samples at floor scale, because a chip in your hand lies about how it reads across a bay.
Metallic and Quartz, and Where They Belong
Metallic epoxy is worked wet and the marbling comes from technique rather than from the pail, so no two floors match and we say so before you buy. Quartz aggregate broadcast builds a heavier, textured floor that carries color and slip resistance together, which suits a bay that gets wet. Both are more expensive than flake and neither is automatically better in a garage.
Gloss Level in a Bay You Actually Use
Gloss looks best the day it is finished and shows every tire mark and dust film after that. Satin hides ordinary use and is usually the honest recommendation for a working garage. Matte reads flat and hides the most. We put all three under the same light before you choose, because this is the decision people most often regret.
Our Step-by-Step Epoxy Garage Floor Process
Slab Assessment and Written Scope
We look at the slab, test moisture where the age or condition calls for it, identify what is moving and write a scope naming the product, the system build and the finished mil thickness. Nothing is ordered before that is agreed.
Clearing the Bay
A floor cannot be prepared around shelving, a freezer and twenty years of boxes. We agree in writing who moves what and where it goes before the day, which is the conversation that otherwise happens badly on the morning of the job.
Mechanical Preparation
Every slab is opened mechanically with a diamond grinder or a shot blaster to the profile the system needs — and hard concrete takes a soft bond, which is the opposite of what most people expect. We do not acid etch and we do not coat over an existing sealer.
Crack and Joint Detailing
Working cracks and control joints are routed, filled with a flexible sealant and honored through the finished floor rather than skimmed over. This is the step most often skipped, and it is the one that decides whether the floor splits along an old line in its first dry summer.
Coating, Cure and Handover
Base coat, broadcast where the system uses one, then the wear coat, each applied inside its own recoat window. We schedule against the slab surface temperature and the dew point rather than the air temperature, and we hand over with a return-to-service date for foot traffic and for vehicles, not a vague promise.
