Flake Epoxy Floors in Austin, TX
A flake epoxy floor is a two-part epoxy primer and base coat with vinyl chips thrown into the wet base until no resin shows, then locked under a clear topcoat; in Austin, the slab's moisture reading, its cracks and joints and the temperature on the day decide how it is built. Two-part means a resin and a hardener, part A and part B, that cure by chemical reaction once blended, as Sherwin-Williams describes 100 percent solids epoxy. The median City of Austin housing unit was built in 1994, per table B25035 of the Census Bureau's 2020-2024 American Community Survey, and detached single-unit houses account for 209,772 of its 483,071 units (table B25024), about 43.4 percent by our division. We lay the chips into epoxy, polyurea or polyaspartic bases; our polyaspartic floor coating page covers the fast-cure ones.
None of the national price surveys we cite prints a line for a full-broadcast flake floor, and none prices Austin, so the nearest figures are their epoxy garage rows. HomeGuide's survey dated February 3, 2026 sorts garages by floor area: 288 to 392 square feet for one car runs $1,200 to $3,900 installed, 400 to 576 square feet for two cars $1,600 to $5,800, and 576 to 864 square feet for three cars $2,300 to $8,600. Angi, in August 2026, puts a three-car garage at $2,250 to $9,000, a one-car at $750 to $3,000 and a two-car at $1,500 to $6,000. For the chips, HomeGuide's polyaspartic survey of November 18, 2024 says "decorative flakes, custom colors, or patterns can add $0.50 to $2.00 per square foot." Angi lists the resin, the floor's size and the preparation as what drives a total. Our garage floor cost page lays out every survey row with its date.
Sherwin-Williams' Resuflor Deco Flake SB application instructions put a number on every layer. The epoxy primer goes on at 3 to 5 mils, a mil being a thousandth of an inch of film. The base coat follows at 10 to 12 mils, the flake is thrown into it wet at 0.2 pounds per square foot, and loose chips are later swept and vacuumed away. Sixteen mils of epoxy grout coat cover the flake, and a urethane seal coat at 535 square feet per gallon closes the floor. Laticrete's term for the broadcast is "to refusal or rejection (full coverage)," with no resin showing, and Torginol's sheet puts each chip at about 5 mils thick. Volume solids, the fraction of the mixed liquid left behind as cured film, matter as well: in Sherwin-Williams' carrier-based example, "a wet film of 7 mils may result in a dry film of 3 to 3.5 mils."
We test the slab before we choose the system, because water vapor rising from the ground can lift a coating, the failure Sherwin-Williams calls disbondment. The chosen products' documents set the test and the limit. One example is Form G-1, Sherwin-Williams' surface preparation guide: for substrates receiving non-permeable flooring it takes in-situ relative humidity probe results under ASTM F2170 at or below 80 percent, and calcium chloride results under ASTM F1869 of not more than 3 pounds per 1,000 square feet over 24 hours. Then the slab is ground with diamond tooling to the concrete surface profile, or CSP, the system names, a graded roughness the primer keys into, numbered CSP 1 to CSP 10 under ICRI 310.2R. Form G-1 assigns CSP 5 to Sherwin-Williams' flake systems; acid etching, its own article says, "tends to produce a CSP-1 to CSP-2 profile." Our grinders carry the dust collection named in Table 1 of federal OSHA's silica rule, 29 CFR 1926.1153, with HEPA vacuuming between passes indoors.
Each cure time on a data sheet is stated at a temperature. Sherwin-Williams' Resuflor Deco Flake SB instructions allow light traffic after 24 hours "at 75 degrees F, 50% relative humidity," and full properties develop over 14 days. Sika's Sikafloor-264 sheet (September 2026), for an epoxy Sika lists for garages and broadcast floors, prints foot traffic, light traffic and full cure at about 12 hours, 2 days and 7 days at 68 degrees F, and about 8 hours, 36 hours and 4 days at 86 degrees F, with application capped at 85 degrees F. Camp Mabry's 1991-2020 normals from NOAA put the normal daily high at 97.8 degrees F in August, 96.6 degrees F in July and 93.2 degrees F in June, all outdoor air rather than slab or garage readings. Your part is to empty the garage before we arrive and keep cars off until the vehicle time we give you in writing.
A written quote starts with a visit: we measure the garage, test the slab, look at every crack and joint, and ask how long the car can stay out. Tell us the slab's age if you know it; Sherwin-Williams' Form G-1 calls 28 days the industry standard cure and warns that a slab can still hold excess moisture by then. Mention old paint, sealer or an earlier coating, which Sherwin-Williams lists among floors that need special preparation. Our free written quote lists the products by name, each step, the dates and the price; it spells out what the price covers and what it leaves out, and prices any moisture-mitigating primer separately, on its own line. To book the visit, send us the garage size and photos of the worst cracks.
Signs a flake floor fits your garage
A flake floor makes sense when the slab is sound and the garage works hard. Torginol, the flake maker, says the "FLAKE texture provides anti-slip qualities," and Laticrete says the chips "May be used to help hide small substrate imperfections." The moisture test still has the last word.
- The slab is sound but patched or rough, which Westcoat warns a thin coat "may not hide" and chips, Laticrete says, may help hide if small.
- Cars come in warm from the road and park in the same spots, where Euclid Chemical says heat drives plasticizers out of tire rubber.
- The cracks you see are hairline or old shrinkage cracks that have stopped moving, not a slab that rocks, heaves or sinks.
- A moisture test by ASTM F2170 or ASTM F1869 reads inside the limit printed on the chosen primer's data sheet.
- You want grip when the floor is wet, and Sherwin-Williams' Resuflor Deco Flake II submittal calls for aluminum oxide back-rolled into the grout coat.
- The garage can stay empty through the cure: 24 hours for Laticrete's polyaspartic chip floor, or three days before driving on epoxy in Rust-Oleum's comparison.
If the slab is crumbling, rocking, heaving or sinking, coating is not the next step; Wolverine Coatings calls such a slab "an unlikely candidate for coating without repair." Our concrete resurfacing page covers worn and scaled slabs that need work first.
Shrink-swell clay, slab cracks and what a repair can follow
A filled crack can reopen if the slab moves, and the NRCS rates two Blackland Prairie clays high in shrink-swell potential, but no source here measures what that does to a slab. The Handbook of Texas says the Balcones Escarpment divides Travis County and "separates the Edwards Plateau in the west from the Coastal Plains." For Houston Black, the NRCS series description records "High shrink-swell potential and cracks that are 1.3 to 10 cm (1/2 to 4 in) wide" in dry periods, cracks that stay open "90 to 150 cumulative days in most years." Heiden, a series the NRCS established in Travis County in 1969, shares that rating with narrower dry-period cracks, 1 to 8 cm (0.5 to 3 in) wide. Those cracks are in soil; for concrete, NRMCA's CIP 4 says a slab "deflects depending on load and support conditions" and lists "Improper subgrade preparation" among the causes of cracking.
Fillers stretch little: Metzger/McGuire's bulletin T18 puts the expansion of epoxy and polyurea fillers at "15% or less" in the usual case, and Euclid Chemical rules its Dural 340 epoxy filler out for "any type of moving cracks." So we fill and grind flush the cracks that have stopped, saw moving joints back through the new floor, at least 3/4 inch deep by 1/4 inch wide per Sherwin-Williams' joint guideline, and tell you in writing which repaired lines may show again. The Austin numbers page lists the soil series and their NRCS wording.
Hot-tire pickup: what the makers say causes it and stops it
Hot-tire pickup, a coating lifting or staining where warm tires sit, has two causes in the sources: plasticizer migration out of the tire, and a slab not prepared to hold the coating. Euclid Chemical's bulletin CP-22 explains the first: tire rubber carries plasticizers to stay soft, and "When the car is driven, the tires heat up, causing the plasticizers to soften and leach out of the rubber." Acrylic cure-and-seal products mark most, having "minimal 'crosslinking'," while epoxy and urethane coatings are "much more crosslinked" and "less likely to tire mark." Sherwin-Williams calls its acrylic ArmorSeal Tread-Plex "Not recommended for areas subject to hot tire pickup"; Laticrete lists "Resistant to hot-tire pickup" for its Spartacote Flex SB polyaspartic. The second cause lives in old concrete: a 2012 trade article by an H&C Decorative Concrete Products representative says paraffin from hot tires works 1/16 or 1/8 inch into a slab and turns into a bond breaker, and that "Concrete preparation is the key to preventing hot tire pickup." Once a plasticizer stain is inside a finished coating, Tennant's maintenance guide calls such marks "impossible to remove" and says only recoating clears them; its prevention is to "Place a barrier between the tires and coatings." The epoxy garage floor pros and cons guide sets this beside epoxy's other weak points.
Pot life and cure set against Camp Mabry's summer normals
Heat shortens both the time a mixed epoxy can be spread and the time each coat needs, and Austin's summer sits above the temperatures most data sheets print. Pot life, the window between mixing and the point the material can no longer be spread, is about 25 minutes at 68 degrees F for Sikafloor-264 but only about 15 at 86 degrees F, and Rust-Oleum's chart for its EpoxyShield kit allows just 1 hour of use at 81 to 85 degrees F, against 2 hours at 60 to 70 degrees F. The sheets set ceilings too: 85 degrees F for Sikafloor-264 and the EpoxyShield kit, 90 degrees F for Westcoat's EC-36. Camp Mabry's 1991-2020 normals count 122.8 days a year reaching 90 degrees F or more, and 28.7 days reaching 100 degrees F or more.
Those are outdoor air figures. Before mixing, our crew reads three numbers on site, the air temperature, slab temperature and dew point, and holds the slab 5 degrees F or more above the dew point, which the Sika and Sherwin-Williams sheets require. Sherwin-Williams' flake instructions add that coats on concrete "should occur while temperature is falling," since air in a warming slab expands and is "forced out" through the wet film as bubbles, in its outgassing article's words. In July and August that means coating when measured temperatures are inside the window and falling.
Choosing the base coat under the chips
The chips and the clear coat look much alike in every version of this floor; what changes is the resin underneath and who lays it. Three facts decide among the options below: the moisture reading, the garage temperature on the day and how long the car can stay out.
Epoxy primer, base and grout coat
This is the four-coat build in Sherwin-Williams' Resuflor Deco Flake SB instructions: epoxy at 3 to 5 mils, 10 to 12 mils under the chips, a 16-mil grout coat and a urethane seal. In Citadel's comparison table, epoxy stays workable for 20 to 60 minutes and its polyurea base for 20 to 30 minutes. It suits a garage that can stay empty through the cure.
One polyaspartic, base to clear coat
Laticrete's Spartacote chip guideline (TDS 432) uses one polyaspartic throughout: a pigmented 4-mil base at 330 square feet per gallon, chips to refusal, typically 1 to 2 hours before scraping, and a clear coat at 160 square feet per gallon. The floor is out of service for 24 hours. Spartacote Flex SB's data sheet caps slab humidity at 75 percent by ASTM F2170, so it suits a dry slab and a tight schedule.
Owner-applied kit from a store
Rust-Oleum's two-part water-based EpoxyShield kit (technical data ESH-39) builds 3.0 to 3.5 mils dry and goes on only from 60 to 85 degrees F. This Old House's national survey (March 2026) prices DIY epoxy at $2 to $5 per square foot, against $3 to $12 with a hired installer. Stonhard warns that without grinding or shot blasting, "DIY floors can peel, bubble, or crack." It suits a light-use garage and a hands-on owner.
Whichever base we propose, the written quote names it, records the moisture reading and the temperature that decided it, and gives its vehicle time from the data sheet. A reading over the primer's limit appears as a separate moisture-mitigating primer line.
Flake Epoxy Floors FAQs
How much does it cost to epoxy 1,000 square feet of flooring?
Multiply the area by a survey's national rate. At HomeGuide's February 2026 rate, $4 to $10 a square foot installed, 1,000 square feet comes to $4,000 to $10,000; at This Old House's March 2026 hired rate, $3 to $12, it comes to $3,000 to $12,000. The multiplication is ours, not a survey's, and neither survey prices a full flake broadcast or Austin itself. Grinding, crack repair and any moisture-mitigating primer move a written quote within or beyond those ranges.
What is the downside of epoxy flooring?
Epoxy's downsides, in its makers' own documents, are color change in sunlight, dependence on a dry, well-prepared slab, a cure measured in days and slickness when wet. Sherwin-Williams' ArmorSeal 1000 HS sheet says "Epoxy coatings may darken or yellow following application and curing," and its blistering article says disbondment may come from moisture vapor in the slab. Rust-Oleum puts epoxy at three days before driving, and Sherwin-Williams warns smooth floors "can become slippery" when wet. Chip texture answers the slip point.
Is it worth getting your garage floor coated?
Coating pays off when the slab is sound, tests dry enough for the system and takes daily car traffic, though not as an investment in the house: Angi's August 2026 page says "An epoxy floor will not directly increase your home's value." What a coating buys is a sealed surface. Laticrete notes its coating systems are nonporous, so dirt stays on top to be cleaned, and Euclid Chemical says epoxy and urethane coatings tire-mark less than acrylic sealers. If the slab fails its moisture test or heaves, fix the slab first.
Will cracks come back through a flake floor in Austin?
Some can, because a crack that is still moving can reappear through a coating laid over it. The NRCS rates Houston Black, a Blackland Prairie clay, at "High shrink-swell potential," but no source we cite measures how a given Austin slab moves. Before the primer we fill and grind flush the cracks that have stopped, cut moving joints back through the finished floor, and tell you in writing which repaired lines may show again. Chips may help hide small flaws, Laticrete says, but they do not stop a slab from moving.
