Huntington Floor Coating Numbers: Houses, Climate, Standards and Costs

Last reviewed 2026-10-02. Journalists, researchers, and community groups are welcome to cite any figure on this page with attribution and a link.

This page holds the numbers behind floor coating work in the Town of Huntington, in five tables: the houses, the climate a slab lives in, the standards, the coating data sheets and the published costs. Each figure carries its source and its vintage. The housing figures are the Census Bureau's 2020-2024 American Community Survey estimates. The climate figures are NOAA's 1991-2020 normals for Centerport, a station inside the Town, with Islip for snowfall and Farmingdale's 2006-2020 hourly normals for dew point. The standards are ICRI Guideline 310.2R, the ASTM moisture tests, OSHA's silica rule and New York State's VOC rule. Where a figure is computed from two published numbers, such as a share or a distance, the text says so.

Read each table for what it is. A Census estimate has a margin of error, and it counts houses and vehicles, not garages. A NOAA normal is an average of outdoor readings at a weather station, over 30 years for the 1991-2020 set; it is not the temperature of a slab. A data sheet figure belongs to one named product at a stated temperature, not to all coatings, and we install more than one system. A survey price is national: no survey publishes a Huntington, Suffolk County or Long Island price, and none is our price, as our epoxy flooring cost page explains. None of these numbers measures your floor: we visit, measure and test the slab before we send a free written quote. Our epoxy flooring pros and cons guide covers the downsides and the rules.

The houses: structure type, year built and vehicles

The Town of Huntington is mostly detached houses, and the 1950s and 1960s are its two largest building decades. The Census Bureau's 2020-2024 American Community Survey estimates 73,982 housing units in the Town, of which 62,121, or 84.0 percent, are one-unit detached houses (table B25024). The median year built is 1963 (table B25035), and 37,579 units, or 50.8 percent, were built from 1950 to 1969 (table B25034). Of the Town's 71,542 households, 88.7 percent own their homes (table B25003), and 51,038, or 71.3 percent, have two or more vehicles available; 29.3 percent have three or more, and 4.0 percent have none (table B25044). These tables count houses and vehicles, not garages. Our garage floor epoxy page explains why a slab of that age is tested for moisture before it is coated.

The hamlets differ. The Census Bureau reports each one as a census designated place, a statistical area and not a legal boundary. The same survey puts the median year built at 1956 in the hamlet of Huntington, 1961 in Huntington Station, 1970 in Dix Hills and 1983 in Melville, where an estimated 34.9 percent of housing units were built in 2000 or later. Dix Hills is an estimated 94.8 percent one-unit detached, with two or more vehicles at 83.5 percent of households; Melville is 59.0 percent detached and 22.8 percent one-unit attached. For comparison, Suffolk County as a whole has a median year built of 1970, one-unit detached houses at 79.7 percent of housing units and two or more vehicles at 67.8 percent of households.

Source: U.S. Census Bureau, American Community Survey 2020-2024 5-year estimates, tables B25001, B25024, B25034, B25035 and B25044. Every figure is a survey estimate with a margin of error; the +/- on the median row is the published margin. Shares are computed from the published estimates and rounded to one decimal place; the 2000 or later row adds three periods. The hamlet columns are census designated places with small samples, and in the smallest cells the margin is larger than the estimate (Melville, built 1940 to 1949: 29 units, plus or minus 36). The structure rows leave out the two-unit, three- or four-unit, mobile home and boat, RV or van categories. The vehicle row is a share of occupied housing units. Suffolk County, same survey: 580,772 housing units; 79.7% one-unit detached; 17.2% built 1950 to 1959; 19.7% built 1960 to 1969; median year built 1970; 67.8% of households with two or more vehicles.

The climate a slab lives in: three NOAA stations

Centerport, a NOAA station inside the Town of Huntington, averages 88.1 nights a year with a low at or below 32 degrees F in the 1991-2020 normals, 23.9 of them in January. Its normal January low is 24.5 degrees F and its normal July high is 83.2 degrees F. NOAA's middle dates for the last spring freeze and the first fall freeze at Centerport are April 9 and November 10, and its freeze-free period is 215 days at the 50 percent level. Centerport has no snowfall normal. Islip's, measured at Long Island MacArthur Airport in the Town of Islip, is 31.8 inches a year, and the days a year with snowfall of 1.0 inch or more average 7.9. All of these are outdoor air readings at a weather station, not slab or garage temperatures.

Coating data sheets set their limits by temperature and by dew point, the temperature at which moisture condenses out of the air. The data sheet for Sherwin-Williams ArmorSeal 1000 HS, revised August 10, 2021, sets a minimum of 50 degrees F and requires application at least 5 degrees F above the dew point; Rust-Oleum's sheet for its EpoxyShield water-based kit (ESH-39) calls for 60-85 degrees F. That is why the table counts the days reaching 50 and 60 degrees F: 4.5 and 0.6 in a normal January at Centerport. At Farmingdale Airport, NOAA's 2006-2020 hourly normals for mid-October put the air temperature at 7 a.m. standard time at 53.9 degrees F and the dew point at 47.6 degrees F, a calculated difference of 6.3 degrees F, against 17.1 degrees F at 2 p.m. We measure the air temperature, the slab temperature and the dew point before we mix.

Centerport (NOAA station USC00301309, inside the Town of Huntington): 1991-2020 normals; for the year, a normal high of 60.8 and low of 45.1 degrees F and 88.1 nights at or below 32 degrees F; middle freeze dates April 9 and November 10. A night at or below 32 degrees F is NOAA's count of days with a minimum at or below it; a day reaching 50 or 60 degrees F is a day with a maximum at or above it; the counts are 30-year averages, so they carry decimals. Farmingdale (NOAA station USW00054787, Republic Airport, Town of Babylon): 2006-2020 hourly normals for calendar day 15 of each month at 7 a.m. standard time. Islip (NOAA station USW00004781, Long Island MacArthur Airport, Town of Islip): 1991-2020 normals; for the year, 31.8 inches; NOAA has no snowfall normal for Centerport. Calculated from published coordinates, Centerport is about 2.6 miles from Huntington Town Hall, Farmingdale about 9.6 miles and Islip about 17.6 miles. Every temperature is outdoor air at a weather station, not a slab or garage temperature.

The standards in numbers: profile, moisture, dust, VOC

Concrete surface profile (CSP) is the roughness a slab is given so a coating can grip it. ICRI Guideline 310.2R-2013, from the International Concrete Repair Institute, numbers it CSP 1 to CSP 10 and names each profile by the method that typically produces it: CSP 1 is acid-etched, CSP 2 is grinding and CSP 3 is a light shotblast. The guideline also sorts coatings by thickness in mils, thousandths of an inch: thin films at 4 to 10 mils and high-build coatings at 10 to 40 mils. The profile set against each thickness in the table is a coating maker's, from Wolverine Coatings' bulletin, not ICRI's own table. We grind with diamond tooling instead of acid etching, to the profile the system's data sheet calls for; our epoxy floor installation page gives the order of work.

A moisture limit is the coating maker's, measured by an ASTM test method. ASTM F1869, the calcium chloride test, reports pounds of moisture over 1,000 square feet in 24 hours, and Sherwin-Williams' Form G-1 allows not more than 3 pounds. ASTM F2170 reads relative humidity inside the slab with probes, and the makers' limits under it run from 75% to 85% in the table. Our basement floor epoxy page explains both tests. The federal OSHA silica rule for construction, 29 CFR 1926.1153, limits a worker's exposure to respirable crystalline silica, which concrete contains, to 50 ug/m3 (micrograms per cubic meter) as an 8-hour time-weighted average (TWA). New York State's 6 NYCRR Part 205 limits the solvent content (VOC, volatile organic compounds) of floor coatings to 100 grams per liter from 1/1/2021; the federal limit for floor coatings in 40 CFR Part 59 is 400 grams per liter.

CSP is the concrete surface profile number of ICRI Guideline 310.2R-2013, whose figure captions name each profile by the method that typically produces it. The two thickness rows are Wolverine Coatings' table and the flake and quartz row is Sherwin-Williams' requirement for its own systems; neither is a universal rule. ASTM F1869 and ASTM F2170 are test methods, and each limit is the named maker's. ug/m3 is micrograms per cubic meter; TWA is a time-weighted average. New York State's limit for floor coatings was 250 grams per liter until 12/31/2020, and its limit for industrial maintenance coatings is 250 grams per liter from 1/1/2021; the federal limit for floor coatings (40 CFR Part 59, Subpart D) is 400 grams per liter.

What the data sheets say: epoxy, polyaspartic, polyurea

A data sheet figure is one product's figure at a stated temperature, not a rule for all coatings. The eight rows are published sheets for four epoxies, three polyaspartics and one polyurea base coat; each maker is named as the source of a figure, not as the brand on your floor. Solids is the share of the wet coating that stays on the floor as film, printed by volume on some sheets and by weight on others. Pot life is the time a mixed batch can be used; recoat is the wait before the next coat. Every time on a sheet depends on temperature: Sherwin-Williams' ArmorSeal 1000 HS data sheet, revised August 10, 2021, gives foot traffic at 24 hours at 77 degrees F and 48 hours at 50 degrees F, and heavy traffic at 48-72 hours at 77 degrees F and 4-5 days at 50 degrees F.

The polyaspartic and polyurea rows return to service sooner. Laticrete's Spartacote Flex SB data sheet (DS-864-0822) gives a working time of 20 - 25 minutes and, at 70 degrees F and 50% relative humidity, foot traffic at 2-4 hours and vehicular traffic at 24 hours. Our polyaspartic floor coating page covers working time and humidity. Where a cell reads not stated, the figure is not in the sheet text this page was built from, and we leave the gap. We give you the foot traffic and vehicle traffic times for your floor in writing, from the data sheets of the products on it.

Each row is that product's published sheet at the date or revision shown, not a rule for all coatings. Solids are by volume or by weight as each sheet prints them. Where a sheet names a different kind of traffic, the cell says so. ArmorSeal's drying schedule is stated at a 6.0 mil wet film. The sheet text behind this table gives no temperature for EpoxyShield's traffic times, for EC-36's recoat time or for Polyurea-350's pot life, and it states Flex SB's 70 degrees F and 50% RH basis with the traffic times, not with the working time or the recoat times. RH is relative humidity. Where a cell reads not stated, the figure is not in the sheet text this page was built from.

Published cost benchmarks: surveys, wages, tax and fees

Every survey price in this table is a national figure. No survey publishes a Huntington, Suffolk County or Long Island price, and none of these is our price. HomeGuide's February 2026 epoxy flooring survey prints $4 to $10 per square foot installed; Angi's August 2026 data prints $2 to $12; HomeAdvisor's June 2026 page gives an average project of $2,526. The surveys disagree, so each row names its survey and its date, and we do not average them. The Bureau of Labor Statistics row is a wage paid to workers, not a price charged to customers: for May 2025 it puts the mean hourly wage of construction and extraction occupations at $39.49 in the New York-Newark-Jersey City metropolitan area, the whole area and not Long Island alone, against $31.42 in the United States.

The tax and permit rows are government figures. New York State's Publication 718, effective March 1, 2025, lists Suffolk County's combined state and local sales tax rate as 8 3/4 percent. Our written quote states the tax treatment of your job; the State or a tax professional has the final word. Town of Huntington Code section 87-23, amended 11-6-2025, puts a non-refundable $50 application fee on every permit application and sets the minimum fee at $125 for residential uses and $625 for nonresidential uses. The schedule says what a permit costs, not which jobs need one; the Town's guideline says "Please contact the Building Department before working on structures." The four incorporated villages inside the Town issue their own building permits.

Survey rows are national figures from the named price survey at the date its page shows. No survey publishes a Huntington, Suffolk County or Long Island price, and none of these is our price. The Bureau of Labor Statistics row is a wage paid to workers, not a price charged to customers, for the whole metropolitan area and not Long Island alone. Publication 718 prints the rate as a fraction. The permit fees apply where the Town requires a building permit; the fee schedule does not say which jobs need one.
