Garage Floor Epoxy in Amarillo, TX
Garage floor epoxy is a coating mixed from two liquids, a resin and its hardener, that harden by chemical reaction rather than by drying and lock into concrete that has been ground open; in Amarillo, temperature runs the schedule. Sika's data sheet for Sikafloor-264, an epoxy it lists for garages, sets 50 degrees F as the lowest air temperature for applying it and gives about 10 days at that temperature to full cure. NOAA's 1991-2020 normals for the Amarillo airport give January an average high of 52.2 degrees F and an average low of 24.9 degrees F. Those are outdoor readings, not your slab, so our crew takes readings on the concrete and in the air, dew point included, before anything is mixed. Below are the layers, the preparation, the cure clock and the prices.
Size drives most of the bill for a garage. HomeGuide's February 2026 national survey prices installed epoxy in one-car garages (288 to 392 sq ft) at $1,200 to $3,900, two-car garages (400 to 576 sq ft) at $1,600 to $5,800 and three-car garages (576 to 864 sq ft) at $2,300 to $8,600. Angi's data, national and updated in August 2026, runs from $750 to $3,000 for a one-car garage it sizes at 250 sq ft up to $2,250 to $9,000 for a three-car at 750. In Angi's account, resin type and floor size, plus surface preparation, set most of the price, and HomeGuide notes that cracks get filled before the epoxy and that colored flakes cost extra. None of these surveys prices Amarillo. Our epoxy cost breakdown sets the DIY and repair rows next to them.
A flake floor is a stack of layers, each measured in mils, thousandths of an inch. Sherwin-Williams specifies its Resuflor Deco Flake SB floor in this order: first 3 to 5 mils of epoxy primer, then 10 to 12 mils of epoxy base coat flooded with decorative flake at 0.2 pounds per square foot, then 16 mils of epoxy grout coat over the chips, and last a urethane seal coat. Broadcasting to rejection, Laticrete explains, means adding chips to the wet resin until "There should be no resin showing." Torginol makes its flakes about 5 mils thick. Volume solids, meaning how much of the mixed material is still on the floor once it cures, sets the film each pass leaves: Sherwin-Williams pairs 5.0 to 8.0 wet mils of ArmorSeal 1000 HS, a 65 percent solids epoxy in colors, with 3.0 to 5.0 dry.
The moisture test comes first, by the method the chosen product's sheet names. Sika accepts in-situ probe readings under ASTM F2170 of up to 85 percent relative humidity for Sikafloor-264, and Sherwin-Williams' Form G-1 holds its non-permeable floors to 80 percent by probe or, by the calcium chloride test of ASTM F1869, to "not more than 3 pounds of moisture per 1,000 square feet per 24 hours." Grinding comes next. ICRI Guideline 310.2R grades concrete surface profile, the texture the resin keys into, from CSP 1 to CSP 10, and Form G-1 places Sherwin-Williams' decorative flake systems at CSP 5. Acid etching, Sherwin-Williams says, tends to leave CSP 1 to CSP 2, so our crews grind with diamond tooling instead. Our grinders use vacuum dust collection, an option Table 1 of OSHA's 29 CFR 1926.1153 gives for floor grinders, with a HEPA vacuum run between passes.
Cure runs on slab temperature, and the sheets print it at fixed points. Sika's schedule for Sikafloor-264 at 50 degrees F reads about 24 hours before foot traffic, about 3 days before light traffic and about 10 days before full cure. At 68 degrees F the steps fall to roughly 12 hours, two days and a week, and the next coat must go on within 24 hours instead of 48. Sherwin-Williams times a sealing coat for a slab that is warm and cooling, so air in the concrete is not pushed up into bubbles, and NWS Amarillo's study of 1892-2009 found daily ranges of 50 degrees or more in the months from September through April. Before we come, empty the garage and tell us about any sealer or old paint. Afterward, keep water off for the 24 to 48 hours Sherwin-Williams gives its Resuflor Deco Flake II floors; your foot and vehicle times come in writing.
Free written quotes come after we have seen the floor. On the visit we measure, test the slab, map cracks, joints and any old coating, and ask when you need to park inside again. The written quote lists the products and steps in order, the dates and the price, what is included and what is not, and any moisture-mitigating primer as a separate price. On permits, the City of Amarillo's Building Safety page lists painting, tiling, carpeting and "similar finish work" among exempt projects but does not name floor coatings, so owners who are unsure ask Building Safety before work starts. To begin, send the garage size, the year the house was built and photos of the worst cracks through our contact page.
Signs an epoxy flake floor fits your garage
An epoxy flake system suits a garage whose slab is dry and sound enough for a non-permeable film, where the car can stay out for several days and the space can be held warm through the cure. You can check most of this before we visit.
- A sheet of 4 mil plastic, 18x18 and taped to bare concrete for 24 hours, leaves no darker patch, the dampness sign Rust-Oleum's basement-coating sheet describes.
- The cracks are hairline or stable: none has widened over the seasons or left one side of the slab higher than the other.
- The garage can be held at 50 degrees F or warmer through the cure without a fuel-burning heater, which Sherwin-Williams links to amine blush.
- Tires already mark an old acrylic sealer on the slab, the plasticizer migration that Euclid Chemical says more crosslinked epoxy resists better.
- The car can stay outside for at least three days, the drive-on wait a Rust-Oleum guide gives for a two-part epoxy.
If the plastic darkens the concrete, a crack keeps moving or the car must be back the next day, the plan shifts to a moisture-mitigating primer, joint work that follows the movement, or a faster chemistry, and any such primer gets its own line in the quote.
Epoxy cure and the dew point against Amarillo's normals
An epoxy garage floor laid in an Amarillo winter cures on the slow end of its data sheet, and on summer dawns the dew point, not the cold, is the closer check. NOAA's 1991-2020 normals for the Amarillo airport put average lows at 25.7 degrees F in December, 24.9 degrees F in January and 27.5 degrees F in February, and NCEI counts 31.0 January days with a low at or under 50 degrees F, the whole month. Sikafloor-264 takes about 10 days at 50 degrees F to reach full cure and about 4 days at 86 degrees F.
The dew point is a separate check. Sherwin-Williams' Resuflor instructions say "Substrate temperature must be at least 5 degrees F above the dew point," the dew point being the temperature at which the air's water starts to condense on a surface, and Sika warns that condensation "may lead to adhesion failure or 'blushing' on the floor finish." Winter air here is dry, with a January 15 dew point of 19.7 degrees F at 06:00 in NOAA's hourly normals, but at that hour on July 15, by our subtraction from the same normals, the air sits only 8.9 degrees F above the dew point. These are outdoor readings, so a thermometer and a dew point meter go on the slab before mixing, and Sherwin-Williams advises against fuel-burning heaters, which "introduce moisture and carbon dioxide into the area, increasing the opportunity for blushing." Our Panhandle weather guide covers freeze dates, dew point and wind.
Hot-tire pickup and the tire paths on a two-car floor
Hot-tire pickup is what happens when tires warm from driving leave marks in a floor finish or pull it loose, and Euclid Chemical's bulletin CP-22 traces it to plasticizer migration: tire rubber holds plasticizers that soften and leach out as the tires heat. Euclid adds that acrylic and styrene-acrylic sealers mark most because their polymers have minimal crosslinking, while epoxy and urethane coatings, being much more crosslinked, are less likely to mark. Sherwin-Williams rates its acrylic ArmorSeal Tread-Plex "Not recommended for areas subject to hot tire pickup," and Laticrete's sheet for its Spartacote Flex SB polyaspartic calls that coating "Resistant to hot-tire pickup." Old residue counts as well.
An H&C representative, writing in a 2012 trade article, says paraffin from tires "penetrates into the surface of the concrete only 1/16 or 1/8 inch deep" and becomes a bond breaker, and that "Concrete preparation is the key to preventing hot tire pickup." Once plasticizer stains are in a coating, Tennant's June 2017 maintenance guide calls recoating the only way to remove them. By our arithmetic from the Census Bureau's 2020-2024 American Community Survey, 62,437 of Amarillo's 89,188 housing units, 70.0 percent, are one-unit detached houses (table B25024), and 46,216 of its 79,741 households, 58.0 percent, have two or more vehicles (table B25044). A two-car floor carries two tire paths, and both get ground and inspected before the primer.
Cracks, joints and the Pullman clay under Amarillo slabs
A coating does not stop a slab from moving, so crack work under an epoxy floor turns on whether each crack still moves. ICRI's June 2022 repair terminology calls a crack active when "the mechanism causing the cracking is still at work" and dormant when it is not likely to become active. Sherwin-Williams sorts joints the same way: control and contraction joints are non-moving, while construction, expansion and isolation joints move and should be carried up through the new floor with a saw cut, because "Not honoring dynamic joints can lead to cracks in the surface." Semi-rigid fillers cannot follow much movement; in Metzger/McGuire's bulletin T18, epoxy and polyurea fillers typically stretch 15 percent or less, while most joints open 50 to 100 percent as a slab shrinks. The ground moves too.
The Pullman soil series, established in Potter County in 1929, has "LE of more than 6.0 cm in the top 1 meter," LE being linear extensibility, the USDA NRCS measure of shrink and swell, and the foundation manual the City of Amarillo posts for builders, the April 2017 Panhandle Residential Foundation Manual, warns that "Long term exposure to moisture will cause fat clays to act as a sponge." The median year built for Amarillo's housing units is 1973, by ACS 2020-2024 table B25035. We fill cracks before priming and tell you which will still show through the finish. The Amarillo floor data page holds the housing and soil tables.
Flake, solid color or a kit: what goes on your slab
The decision is how much system the garage gets. The options differ in thickness, in how much of the slab they hide and in how long the car stays out; each figure is the named maker's or survey's own. For a poured, patterned look without chips, see metallic epoxy floors.
Full epoxy flake broadcast
A primer, a pigmented base coat filled with vinyl chips to rejection, then clear coats that lock the chips in. Sherwin-Williams rates its double-broadcast Resuflor Deco Flake II at a nominal 60 mils, Laticrete's chip sheet says the chips "May be used to help hide small substrate imperfections," and Torginol credits flake texture with anti-slip qualities. It suits a daily-driver garage whose owner can wait out the cure.
Solid-color epoxy coats
Two coats of a two-part epoxy and no chips. For Sikafloor-264, Sika's sheet puts the prime coat at 6 to 10 mils and the wear coat over it at 12 to 15 mils. Sherwin-Williams cautions that "coatings do not hide imperfections in the substrate," and Westcoat says thin coats may not hide patches or rough concrete. It suits a workshop bay where one smooth color that mops clean matters more than hiding a patched slab.
Store-bought water-based kit
Rust-Oleum's water-based EpoxyShield pouch kit builds 3.0 to 3.5 mils dry per coat, against the roughly 11 to 25 mils Sherwin-Williams gives for the thinnest epoxy floor systems. Premade kits run $200 to $700 in HomeGuide's February 2026 national survey. A kit suits a light-duty garage in a warm month, for an owner who accepts a thinner film and more frequent recoating.
If the car has to come back within a day, or the work falls in a month when the garage cannot be held at 50 degrees F, an epoxy base under a faster topcoat, or a full polyaspartic floor coating, changes the schedule.
Garage Floor Epoxy FAQs
How much would it cost to epoxy 1000 square feet of flooring?
Multiply HomeGuide's February 2026 national range, $4 to $10 per square foot installed, by 1,000 and you get $4,000 to $10,000; This Old House's national March 2026 range of $3 to $12 per square foot gives $3,000 to $12,000. Those totals are our arithmetic from each survey's rate, not figures either survey prints, and not local prices. Fixr's national page, updated January 2025, does print a total for an average basement it sizes at about 1,000 square feet: $10,000 to $15,000 in thick-coat epoxy. Thickness, flake, repairs and the slab's condition account for the spread.
What is the downside of epoxy flooring?
Epoxy's weak points are a slow cure in cold weather, sensitivity to moisture in the slab, yellowing in sun and slipperiness when wet. Sikafloor-264 needs roughly ten days at 50 degrees F before it is fully cured. Sherwin-Williams writes that standard epoxy systems are not moisture-tolerant, and Sika warns that its epoxy will discolor in sunlight. Citadel's comparison table rates epoxy's flexibility low, and Sherwin-Williams notes that urethane topcoats are less slippery than epoxy finishes. Moisture tests, grinding, a light-stable topcoat and added grit answer most of these.
Can I epoxy my garage floor myself?
Yes, with a consumer kit, which lays a thinner film in a narrower window than the systems we install. Rust-Oleum's water-based EpoxyShield garage kit wants air and slab between 60 and 85 degrees F, while the Amarillo airport's January highs average 52.2 degrees F in NOAA's 1991-2020 normals, so a winter job needs a heated garage. This Old House (March 2026) puts a DIY 2-car garage of 360 square feet at $720 to $1,800, and HomeGuide's February 2026 survey lists premade kits at $200 to $700, both national. Stonhard, a resin floor maker, warns that floors laid without diamond grinding or shot blasting "can peel, bubble, or crack."
When can I park on a new epoxy garage floor?
Plan on several days, set by the slab's temperature rather than the calendar. Westcoat's EC-36 epoxy allows wheel traffic after 72 hours at 72 degrees F, Rust-Oleum's water-based garage kit asks for 3 days, and Sikafloor-264 needs about 3 days just to reach light traffic at 50 degrees F. HomeGuide's survey, dated February 2026, tells readers "don't walk on it for 16 to 24 hours or drive on it for 2 to 7 days." On a cold slab the long end applies, so your vehicle time comes in writing, from the product's sheet at the temperature we measured.
