The resin isn't the problem; the system and the prep are. A diamond-ground floor with a proper epoxy base and a UV-stable polyaspartic topcoat is a completely different product than the peeling garage your neighbor rolled on ten years ago. Texas-Specific ## What Texas Specifically Does to a Floor Direct sun through an open garage door. 100°+ ambient. Tires that come home hot off asphalt and sit against the floor for hours. That combination is exactly what yellows a bare epoxy and lifts a thin one. Any garage system installed in DFW that doesn't account for UV and heat is on borrowed time. Our System ## What We Install and Why 1. 1 · Diamond-ground profile Industrial grinders open the concrete so the coating mechanically locks in. No acid etch, ever. 2. 2 · Epoxy base coat Metallic pigment or full flake broadcast. This layer builds the floor's body and locks the design in. 3. 3 · UV-stable polyaspartic topcoat The layer that takes tires, sun, and abrasion. No yellowing. Back on the floor in about 24 hours.

They aren't interchangeable, and they don't belong in the same places. ### Epoxy What it is: Two-part thermoset resin. A base component (bisphenol-A or -F) reacts with an amine hardener to form a rigid, high-build film. Where it belongs: The workhorse base coat. High build, strong bond to prepared concrete, excellent chemistry for locking in flake or metallic pigment. Yellows in direct UV — belongs under a topcoat, not exposed. ### Polyaspartic What it is: A fast-curing subset of polyurea. Aliphatic (UV-stable), two-part, cures in minutes to hours instead of days. Where it belongs: The topcoat of choice for modern garage systems. UV-stable, abrasion resistant, and short return-to-use. Unforgiving to install because of the fast pot life. ### Polyurea What it is: Two-part elastomeric coating from the same family as polyaspartic but generally aromatic and faster-setting. Where it belongs: Common in truck-bed liners and industrial joint fill. Aromatic polyureas yellow in UV, so they aren't the right choice as a decorative topcoat. ### Polyurethane What it is: Two-part resin with excellent flexibility and abrasion resistance; slower cure than polyaspartic. Where it belongs: A legitimate topcoat option, especially in food and pharma facilities. Slower cure and more sensitivity to humidity has pushed most residential installs toward polyaspartic. ### Acrylic sealer What it is: Water- or solvent-based single-part film-former. Thin, breathable, low build. Where it belongs: Correct for exterior stamped concrete and driveways where breathability matters. Wrong for garages — it's a sealer, not a coating. ### Big-box "epoxy" paint kits What it is: Water-based, single-part product marketed as epoxy but chemically closer to a modified latex paint. Ships with an acid-etch packet. Where it belongs: Priced as a weekend project. Performs like paint over an under-prepped slab. Peels in sheets, typically inside 2–3 years. The $300 Kit ## Why the Big-Box Kit Fails The rolled-on kit sold at every hardware store is not the same product a professional installs. Chemically it's a water-based, single-part product much closer to a modified latex paint than to true two-part epoxy. It comes with a plastic packet of muriatic-acid crystals for "prep," and it lays down 2–4 mils of film total. Four things guarantee it fails: the acid etch doesn't create a mechanical profile the coating can bond to, single-part chemistry never cross-links to full hardness, the film is too thin to absorb impact, and water-based coatings are humidity-sensitive during cure — a garage in DFW summer often isn't dry enough for the film to close properly. Realistic outcome: it looks fine for the first summer, peels around the door line by month 18, and lifts under tires by year three. That's not a knock on the DIY homeowner — it's a knock on a product marketed as something it isn't. Interrogating a Bid ## Reading a Spec Sheet Four terms that let you tell a real system from a marketing brochure. ### Mils (film thickness) One mil equals 1/1000 of an inch. A big-box roll-on kit lays down 2–4 mils total. A serious garage system builds 20–40 mils across base and topcoat. Thickness is what determines whether a floor absorbs impact or telegraphs every dropped wrench through to the concrete. ### Solids content The percentage of the can that stays on the floor after cure. 100% solids means no shrinkage and no VOC off-gas. 40% solids means more than half the coating evaporates and the film you paid for is significantly thinner than what came out of the pail. ### Pot life How long the mixed product stays workable before it kicks. Epoxy has hours. Polyaspartic often has minutes. Short pot life is the reason polyaspartic installs punish inexperienced crews — mix a batch too big and it sets in the pail. ### UV stability (aliphatic vs aromatic) Aliphatic chemistry (aliphatic polyurea, polyaspartic, urethane) resists UV. Aromatic chemistry (standard epoxy, aromatic polyurea) yellows and chalks. Any topcoat exposed to sunlight has to be aliphatic — the label often just says "UV-stable." Texas Summer, Specifically ## Temperature & Humidity Windows Every coating on the market has a manufacturer-published temperature and humidity window for application. Slab temperature — not air temperature — is what matters, and in DFW summer a west-facing garage slab can sit 15–25°F above ambient by mid-afternoon. Coating a hot slab flashes the resin, shortens pot life dramatically, and can trap solvent under the film. Humidity affects cure the other direction. Polyaspartic and polyurethane are moisture-sensitive; applying below the dew point risks blush (a milky haze) and adhesion loss because condensation forms on the slab as it cools. Reputable installers check slab temperature with an IR thermometer and calculate dew point before mixing. Practically, this is why serious DFW crews start early, work the shaded bay first, and reschedule when a storm front pushes the dew point into the danger zone. If a contractor tells you weather doesn't matter, they're not paying attention to their own product data sheets. Flake, Quartz, Metallic ## The Decorative Layer Is Separate From the Chemistry People routinely conflate the look of a floor with the system underneath it. They're independent choices. Flake, quartz, and metallic are all decorative media that get suspended in or broadcast onto a base coat — the same underlying epoxy-plus-polyaspartic system can carry any of the three. Flake broadcast is vinyl chips scattered into wet base for texture, slip resistance, and a mottled look. Quartz broadcast is real crushed quartz — heavier, more durable, and standard in commercial kitchens and pool decks. Metallic uses mica pigments hand-worked while wet to create the poured, dimensional look. Pick the aesthetic that fits the space; the chemistry underneath should be judged on its own merits.
