Most homeowners contact us after doing a significant amount of research and arriving at a short list of remaining questions. This page addresses the questions we hear most often from Katy TX and Greater Houston homeowners — about cost, prep, durability, humidity, timing, and the difference between the products on the market.
A two-car garage (400-500 square feet) runs $1,400 to $2,200 for a full system — diamond grinding, crack repair, 100% solids epoxy base coat, vinyl chip broadcast, and aliphatic polyaspartic topcoat. A three-car garage (600-800 sq ft) runs $1,900 to $3,200. Single-car garages start around $900.
Factors that affect price: the condition of the existing slab (cracks, oil saturation, previous coatings that need removal), the chip blend and coverage density selected, and whether the project includes any adjacent concrete like walkways or a patio. We provide written quotes after an on-site assessment — over-the-phone pricing on an unseen slab is often inaccurate in either direction.
Most residential garages install in a single day. Surface preparation (grinding, crack repair, cleaning) happens in the morning. The primer and base coat go down mid-day. The chip broadcast follows the base coat. The polyaspartic topcoat goes on last and cures fast — light foot traffic in 4-6 hours, full vehicle traffic the following morning.
Larger garages (three-car and above) or slabs with significant remediation work (heavy oil saturation, previous coating removal) may require two days. We'll tell you at the assessment if your project needs a second day.
High ambient humidity affects the cure chemistry of some epoxy products — certain formulations will blush or fail to cure properly above 85% relative humidity. We use humidity-tolerant products specified for the Gulf Coast climate and monitor conditions on installation day. In most cases, Houston's humidity is a manageable variable rather than a barrier to installation.
The bigger humidity-related concern is moisture vapor in the concrete slab itself. High moisture vapor emission rates from slabs are common in Greater Houston and require a moisture-tolerant primer rather than a standard primer. We test every slab before specifying products.
A polyaspartic topcoat — which is what we use — is rated for hot tire service. Polyaspartic cure chemistry produces a crosslinked polymer network with a higher glass transition temperature than standard epoxy, meaning the topcoat surface stays firm under the heat load transferred by a vehicle tire that's been sitting on hot Texas pavement.
The hot tire pickup failure mode people reference on internet forums is characteristic of water-based epoxy systems — the kind sold in big box stores in a two-part kit. These systems cure to a lower crosslink density and soften under tire heat. Professional 100% solids systems with polyaspartic topcoats don't have this problem.
Yes, in almost all cases. Non-structural cracks — hairlines and narrow separations that are flush on both sides — are standard on Texas garage slabs and are addressed during the surface prep phase: fill with semi-rigid polyurea filler, re-grind flush, proceed with coating. The finished floor shows no trace of the original cracks.
Structural cracks with vertical displacement between the two sides are evaluated individually. If the movement that caused the displacement has stopped, the crack can be stabilized and coated. If movement is ongoing, coating over it produces a floor that cracks again at the same location. We identify which situation applies during the assessment.
A professionally installed full system — primer, epoxy base coat, chip broadcast, polyaspartic topcoat — lasts 15-20 years under normal residential garage use before the topcoat shows meaningful wear. The topcoat is the sacrificial wear layer; when it eventually thins, a topcoat refresh (not a full reinstall) restores the floor to new condition for another 8-12 years.
DIY kits from home improvement stores typically last 2-5 years before peeling, chipping, or fading, because they use lower-solids products applied to unprepared substrates. The 15-20 year lifespan requires both the right products and the right surface preparation.
Yes — the entire floor needs to be accessible for grinding and coating. Vehicles, stored items, shelving, and anything else on the floor needs to be removed before installation day. Wall-mounted storage (shelves, cabinets, tool boards) can stay in place as long as it's mounted high enough that the grinder can reach the floor below it. We typically grind to within 1-2 inches of the wall.
If you have large items with no off-site storage option, we can sometimes stage items in the driveway for the installation day, then move them back in after the topcoat has cured. Ask about this when scheduling.
Sometimes, with conditions. If the existing coating is fully adhered with no peeling or bubbling, is compatible with the new system's chemistry, and can be adequately prepared (abraded or ground) to accept new epoxy, it may be possible to coat over it. We assess this on a case-by-case basis — some existing coatings are good substrates, others aren't.
Failed coatings — anything that's peeling, bubbling, or soft — must be removed before new coating is applied. Applying a new system over a failing old system transfers the failure: the new coating eventually peels along with the old one. Removal adds time and cost but produces a result that holds.
The best way to get accurate answers about your specific garage is a free on-site assessment. We look at the slab, test the moisture, identify any concerns, and walk you through the system that makes sense for your situation. There's no obligation and no high-pressure sales process.
