Garage Floor Epoxy Coating Austin TX
Diamond-ground prep, calcium-chloride moisture testing, full broadcast flake, and a UV-stable polyaspartic topcoat — built for Central Texas garages that sit at 120°F all summer.
A real garage floor epoxy coating in Austin is not a one-day weekend kit and not a “two coats and you’re done” pitch from a high-pressure door-knocker. It’s a documented system: diamond-ground concrete, a moisture-tested slab, structural repair of every crack wider than a hairline, a moisture-vapor-emission primer, a high-build epoxy base, a full broadcast of decorative flake, and a polyaspartic topcoat that survives 105°F summer afternoons, hot-tire pickup off MoPac and I-35, and the freeze-thaw snaps Central Texas gets every January. Austin Epoxy Floor Pros installs that system in two days, in writing, with a 15-year topcoat warranty that’s transferable to the next owner. Call (737) 325-0985 for a free on-site visit and a written, itemized estimate.
What a Garage Floor Coating Actually Means in Central Texas
“Epoxy floor” gets used loosely in Austin marketing. A homeowner shopping the term will find anything from a bargain-bin hardware-store kit to a high-spec polyaspartic-topped showroom build, all calling themselves “epoxy.” The system we install is engineered for the climate we actually live in: triple-digit summer heat, expansive clay soils east of I-35 and Hill Country limestone subgrade west of MoPac, Gulf-driven humidity, and the surprise January cold snap that can drop a garage slab to 28°F overnight. That climate eats cheap coatings within one or two summers. Our system is built around three non-negotiables: full mechanical diamond grinding (no acid etch, no chemical prep), a moisture test on every single slab, and a polyaspartic topcoat instead of a second coat of epoxy. The polyaspartic is what survives the Texas heat.

Our Process
On-Site Estimate
Free 30-minute visit. We measure the garage, photograph every crack and pit, test the slab for moisture with a calibrated relative-humidity probe, and walk you through the system. You leave with a written estimate — not a verbal number, not a “today only” discount.
Diamond Grinding
Day one starts with a planetary diamond grinder pulling the surface of the slab off down to a CSP-2 to CSP-3 profile. That’s the rough texture epoxy needs to bond mechanically — no acid etch, ever. Old paint, old coating, and surface contamination come off in this step.
Crack and Pit Repair
Every crack wider than a hairline gets stitched with a flexible polyurea or chased and filled with a structural epoxy paste. Pits and divots get filled and ground flush. We don’t coat over a crack — the crack telegraphs through within a year if you do.
Moisture-Mitigation Primer
If the moisture test came back at or above the threshold, we apply a moisture-vapor-emission primer first. This is the step skipped by every cheap coating crew in Austin, and it’s the reason their floors blister. Slab-on-grade Austin construction often lacks an under-slab vapor barrier; the primer is the substitute.
Epoxy Base + Full Flake Broadcast
Day two starts with a 100%-solids epoxy base coat rolled across the slab. While it’s still wet, we broadcast vinyl decorative flake to refusal — meaning the floor is fully covered, not the sprinkled “rejection rate” cheaper crews use. Excess flake gets reclaimed for the next job.
Polyaspartic Topcoat + Walk-Through
Once the flake has set, we scrape the floor smooth, vacuum, and roll a UV-stable polyaspartic topcoat over the entire surface. Four hours later we walk you through the finished floor, hand you the warranty paperwork, and confirm you can drive on it the next morning.
Materials We Use
| Diamond Grinder | HTC, Husqvarna, or Lavina planetary grinders with vacuum-shrouded heads — near dust-free, no acid etch ever |
|---|---|
| Crack Repair | Polyurea joint filler (Roadware 10 Minute Concrete Mender) for active cracks; structural epoxy paste for dormant cracks |
| MVE Primer | Penntek or Citadel moisture-vapor-emission primer rated to 25 lb/1000sf MVER |
| Base Coat | 100% solids epoxy (Wolverine Coatings or Citadel Quartzlock) — not solvent-thinned |
| Decorative Flake | Torginol or PolyTek vinyl flake in 1/4″ or 1/8″ chips, your color choice |
| Topcoat | Polyaspartic aliphatic topcoat (Penntek, PolyTek, or Wolverine ArmorClad) — UV-stable, chemical-resistant |
Common Scenarios We See in Austin
Big-Box Kit That Lifted in the First Summer
The most common call we get. Homeowner spent a weekend on a hardware-store acid-etch-and-roller kit, parked the car back in by Sunday night, and by August the kit had lifted in two tire-shaped patches. Our fix: grind the kit off completely, repair the slab beneath, and install the real system. The lifted kit is a sign the slab is sound and just needed real prep.
Drought-Cracked Slab in East Austin
1990s and 2000s slabs in Pflugerville, eastern Round Rock, and East Austin sit on Houston Black clay. The 2011 and 2022 droughts dropped the soil moisture so low the clay shrank and split many slabs across the diagonal. We stitch those cracks with a structural epoxy paste and a fiber reinforcement, then grind flush.
Older Hyde Park / Travis Heights Garage
Pre-1980 garages on the older Austin lots often have no under-slab vapor barrier, no rebar, and surface pitting from decades of oil and brake fluid. We diagnose the moisture situation first — if MVE is high, we either use a moisture-tolerant primer or we tell you honestly that the slab isn’t a coating candidate.
New-Construction Pre-Move-In Coating
Buyer closing on a new build in Teravista, Avalon, or Falcon Pointe wants the floor coated before the moving truck arrives. We coordinate with the builder, verify the 28-day concrete cure is complete, and install before furniture comes in. This is the cleanest install scenario — brand-new slab, no contamination.
Why Austin Homes Need a Garage Floor Coating
Austin garages do double duty — they’re vehicle storage, workshop, gym, beer fridge, and overflow living space. The bare concrete that came with the house was never finished for any of those uses. It’s porous, it stains, it dusts off slowly into the house, and it gets eaten by every oil drip and brake-fluid spill. A real coating system locks the surface, makes spills wipe off, and turns the garage into a usable room. The polyaspartic topcoat is also reflective — a flake-broadcast floor with a clear polyaspartic top bounces light back up and makes the garage feel two stops brighter when the door is open. That matters in Austin because half the year you’re working in the garage with the door cracked for ventilation.
Warranty in Detail
Here is exactly what our 15-year topcoat warranty covers and what it does not. We publish this because most franchise warranties have hidden exclusions that void the coverage on the first claim.
What’s covered
Hot-tire lift, blistering, peeling, delamination, UV chalking, and topcoat fade are covered for 15 years on the product. Workmanship — prep failures, missed crack repair, primer-skipped MVE blistering — is covered for 5 years. Both warranties are fully transferable to the next homeowner when you sell, which is one of the most common asks at closing.
What’s NOT covered
New cracks that appear from slab movement after install (the coating is on top of the slab; if the slab cracks beneath, the coating telegraphs). Damage from dropping heavy objects (jack stands, engine blocks). Damage from automotive battery acid spills that aren’t cleaned within 24 hours. Floors coated over an existing failed coating that we did not strip. We disclose all of this in writing before you sign.
Transferable
Both warranties transfer free of charge when you sell. We register the warranty in your name at install and update it in the next owner’s name with one phone call or email. No transfer fee, no inspection requirement.
How We Quote (Without Quoting on the Phone)
Every garage we visit is different. A 2-car attached garage in a 2015 Teravista house is a different job than a 3-car detached garage on an acre in Bee Cave with limestone subgrade movement. Slab condition, moisture levels, crack count, flake color, and whether the existing surface needs stripping are all variables that affect the number. The crews that quote on the phone do it because they want you to sign before you’ve shopped — they’re guessing high and counting on the deposit. We don’t operate that way. The free 30-minute on-site visit gets you an itemized written estimate with line items you can compare to any other quote, and we don’t ask you to sign that day.
After the Install
Walk-through happens at the end of day two. We hand you the warranty paperwork, the manufacturer’s data sheets on every product used, a small touch-up kit for tiny dings down the road, and a list of cleaning do’s and don’ts — mostly “mop with mild detergent, don’t use harsh solvents.” At 30 days we email a check-in asking how the floor is holding up. At 12 months we come back for a no-charge floor inspection if you want one. If anything has gone wrong — one in maybe 200 floors does — we fix it on the warranty.
Frequently Asked Questions
How long does the coating last in the Austin climate?
The polyaspartic topcoat carries a 15-year product warranty. Real-world service life on an Austin garage with proper diamond-ground prep and moisture mitigation is 15 to 20 years before any recoat is needed. The summer heat does not shorten this — polyaspartic was developed for the bridge-deck market and was engineered to ignore heat.
Will hot tires lift this coating in an Austin summer?
No. Hot-tire lift requires either a coating that softens under heat (epoxy paint kits) or a coating bonded to a slab that was not properly profiled. Our polyaspartic topcoat doesn’t soften, and our diamond-ground CSP-2 to CSP-3 profile gives the coating a mechanical grip the heat can’t peel.
Is the floor slippery when wet?
The polyaspartic topcoat is texturized by the embedded flake — the flake gives the floor a slightly raised surface texture that grips. You can also request additional anti-slip aluminum oxide aggregate broadcast into the topcoat, which we recommend for households with elderly residents or for slick-tile-to-garage transitions. Plain concrete is actually slipperier when wet than our coated floor.
How do I clean it?
Mild dish soap and water with a microfiber mop is the standard. Avoid abrasive cleansers (Comet, etc.), strong solvents, and citrus-based degreasers — those won’t damage the coating immediately but can dull the topcoat over time. Oil drips and brake fluid wipe off with a paper towel and a spritz of mild cleaner.
Can I get the same finish on my patio?
Patios, pool decks, and outdoor concrete are a different system — we use a UV-stable polyaspartic with an aggregate broadcast for slip resistance, not the broadcast flake we use indoors. The flake fades under direct UV outdoors. We’re happy to quote both at the same on-site visit.
Do you do half-garages or just one bay?
Yes — we’ll coat one bay, half the garage, the apron only, or the whole thing. The minimum on-site is usually a single-bay garage; below that, mobilization makes the job uneconomical. Bring it up on the on-site visit and we’ll quote the section you want.
What if I already have a coating that’s failing?
We grind it off. Diamond grinding removes old paint, old epoxy, and surface contamination in one pass. We do not coat over an old coating — that’s a guaranteed delamination job in the Texas heat. Stripping is built into our quote, and the old material is hauled off the same day.
Can you match a specific color or pattern?
Yes. We carry the full Torginol and PolyTek flake catalogs and can pull a custom mix to match a specific color — gray with charcoal accents, warm taupes, cool blues, full earth tones. We’ll bring physical sample boards to the on-site visit so you can see the finish in your own light.
Do you charge extra for moisture testing?
No. The calibrated relative-humidity probe and calcium chloride test are part of the free on-site visit. If your slab tests high, we’ll tell you and quote the MVE primer; if it tests low, no primer needed and the quote is lower. The test results are documented in writing.
How much does a garage floor coating cost in Austin?
