Garage Floor Epoxy in Huntington, NY

Garage floor epoxy is a two-part coating, a resin and a hardener blended on site, that cures by chemical reaction into a film on a ground concrete slab; in Huntington the slab and the weather decide the system: the slab's age and moisture, the salt at the garage door and the temperature on the day. The Census Bureau's 2020-2024 American Community Survey puts the Town of Huntington's median year built at 1963 and finds two or more vehicles at 71.3 percent of households. The system on this page is an epoxy primer and base coat, decorative flake broadcast into the wet base coat until no resin shows, and a clear topcoat, for one-, two- and three-car garages. It is one of the systems we install; our garage floor coating page compares epoxy with polyaspartic, polyurea, floor paint and sealers.

HomeGuide's February 2026 epoxy flooring survey prints $4 to $10 per square foot installed and three garage rows: $1,200 to $3,900 for a 1-car garage of 288 to 392 square feet, $1,600 to $5,800 for a 2-car garage of 400 to 576 square feet and $2,300 to $8,600 for a 3-car garage of 576 to 864 square feet. For a do-it-yourself job, This Old House's March 2026 page prints $480 to $1,200, $720 to $1,800 and $1,120 to $2,800 for 1-car, 2-car and 3-car garages of 240, 360 and 560 square feet, against $3 to $12 per square foot with a hired professional. Angi's August 2026 data names what moves the figure: resin type, floor size and surface preparation, with labor at 33% to 60% of the total. All three surveys are national; none publishes a Huntington, Suffolk County or Long Island price, and none is our price. Our epoxy flooring cost page holds the full tables and the arithmetic by floor area.

Two-part means a resin and a hardener: without the hardener, Sherwin-Williams' technical article on hardeners states, the resin "would remain a near liquid indefinitely". A flake floor is built up in layers, each with a published thickness in mils, thousandths of an inch. Sherwin-Williams' Resuflor Deco Flake SB application instructions (dated 1/25) give one build: an epoxy primer at 3 to 5 mils, an epoxy base coat at 10 to 12 mils, decorative flake broadcast into the wet base coat at 0.2 pounds per square foot, an epoxy grout coat over the flake at 16 mils and a urethane seal coat. Torginol's FLAKE Flooring technical data sheet (version V25010001) gives the flake itself as about 5 mils thick. For one two-part epoxy, the data sheet for Sherwin-Williams ArmorSeal 1000 HS, revised August 10, 2021, gives volume solids, the share of the wet coating that stays on the floor as film, of 65% plus or minus 2% in colors, 3.0 to 5.0 mils dry per coat and 206 to 350 square feet per gallon.

We test the slab for moisture before we choose a system, because water leaving concrete is trapped under a coating and can blister it. Sherwin-Williams' surface preparation guideline (Form G-1, revised 02/26) sets two limits for its resin floors: not more than 3 pounds of moisture per 1,000 square feet per 24 hours under ASTM F1869, the calcium chloride test, and 80% relative humidity or lower under ASTM F2170, the in-slab probe test. We grind the slab with diamond tooling instead of acid etching it. Concrete surface profile (CSP) is the roughness a slab is given so a coating can grip it: ICRI Guideline 310.2R captions CSP 1 as acid-etched and CSP 2 as grinding; Laticrete's TDS 439 recommends CSP-2 by diamond grinding for its broadcast floor, and Form G-1 lists its maker's flake systems at CSP 5. We repair cracks before the primer. Our grinders run with the dust collection the federal OSHA silica rule (29 CFR 1926.1153, Table 1) names for floor grinders, with a filter 99% or more efficient and a HEPA-filtered vacuum between passes indoors.

Cure times are one product's figures at a stated temperature. Sherwin-Williams' ArmorSeal 1000 HS data sheet, for a 6.0 mil wet film, gives foot traffic at 24 hours and heavy traffic at 48 to 72 hours at 77 degrees F; at 50 degrees F, its minimum application temperature, they become 48 hours and 4 to 5 days. NOAA's 1991-2020 normals for Centerport, a station inside the Town, give January a normal low of 24.5 degrees F and a normal high of 37.9 degrees F. Those are outdoor air temperatures, not slab temperatures, so we measure the slab, the air and the dew point, the temperature at which moisture condenses, before we mix; the ArmorSeal sheet requires application at least 5 degrees F above it. You empty the garage first, and Sherwin-Williams' Resuflor Deco Flake II submittal says to keep water off that system's coated surface for 24 to 48 hours. Town of Huntington Code section 141-4 counts building alteration or repair outside 7:00 a.m. to 6:00 p.m. on weekdays as a noise disturbance, so we grind inside those hours.

A written quote starts with four things from you: the garage's length and width, the age of the slab, what is on the floor now (bare concrete, paint, a sealer or an old kit coating) and photographs of the cracks and the apron. We then visit, measure and test the slab. Our written contract gives the start and completion dates and the cost of labor and materials, as Suffolk County Code section 563-21 requires, and names the coating products, as New York's General Business Law section 771 requires. Suffolk County Code section 563-17(D) requires a home improvement contractor's license number in its advertising; when you compare garage floor epoxy installers, ask each for that number.
