Epoxy Flooring and Floor Coatings in Greenlawn, New York

Not every Greenlawn garage holds a car. The Census survey finds no vehicle at all in 6.0 percent of the hamlet's households, and a garage used as a workshop or for storage asks less of its floor than a parking bay. Where tires roll in every day, a two-part resin earns its cost: Euclid Chemical's bulletin CP-22 ranks epoxy and urethane films as more crosslinked than acrylic cure-and-seal products, and so less prone to tire marks.

For a garage that never sees a car, a lighter product can be enough: a one-part acrylic floor paint, or a penetrating silane or siloxane repellent; Prosoco's sheet for one says treated surfaces still breathe. Tires are what rule the paint out, since Sherwin-Williams steers its acrylic Tread-Plex away from hot tire pickup. A floor painted years ago has the old film ground off first. Epoxy's own limits are laid out in our epoxy flooring pros and cons guide.

A Greenlawn job has a fixed order, and its calendar starts with the moisture test. In KTA-Tator's account, the calcium chloride test leaves its sealed dome in place for 60 to 72 hours, so that visit comes days before the grinders do. Under Town Code section 141-4, building work outside weekday daytime hours counts as a noise disturbance, so our crews work weekdays only, and each coat waits for the recoat time its own data sheet prints.

The building changes the plan more than the coating does. The Census survey finds 85.3 percent of Greenlawn's housing units in one-unit detached houses and 6.5 percent in buildings of five or more units, where a garage or basement may be shared. Suffolk County Code section 563-16 writes its home improvement rules for one- or two-family houses, so in a larger building we plan with whoever manages it, down to where residents park during the cure. Grinding dust and leftover resin leave in our truck, never in a street drain.

The Hazeltine report's groundwater depth, about 160 feet, says little about a basement floor. Stonhard writes that the soil under a slab is nearly always damp, at 100 percent relative humidity, and warns that a slab more than 25 years old may have been poured with no moisture barrier beneath it. By the Census survey, only 5.0 percent of Greenlawn's housing units date from 2000 or later, so by house age, most of the hamlet is past Stonhard's 25-year mark.

So the reading comes from your slab: probes set into it, or a sealed calcium chloride dome on it, by whichever test the coating's data sheet uses. Over the limit, a moisture-mitigating epoxy primer goes down first, on its maker's terms, and Sherwin-Williams' Resuprime MVB sheet has two that matter in an older house: a functioning vapor barrier is required, and the slab must not be under hydraulic pressure. A basement that takes in water in heavy storms has the water stopped before any primer.

The one industrial site in Greenlawn our sources describe is the former Hazeltine plant, southeast of Cuba Hill Road and Railroad Street, which the 2010 report gives as about 23 acres zoned I-4 light industry with five main buildings. The report says Hazeltine acquired the property in 1957 and made sheet metal, machine parts and electronic systems there, adding Buildings 3 to 5 from 1960 to 1962 and Building 1 in 1971; BAE Systems owned and operated it in 2010, and two soil vapor samples were taken beneath a basement slab in the former Alodine Room.

A floor with that history is read before it is priced: the site's records on the slab and any work beneath it, calcium chloride tests at Sherwin-Williams' Form G-1 spacing (three in the first thousand square feet, one per thousand after) and a build sized to the wheels and chemicals. Uses change here too: the local historical association says a Broadway school became the Harborfields Public Library, and the Town's 311 article lists a change of use among commercial projects needing a permit. Our sources describe no business on Broadway or Pulaski Road.

The Town's guidelines list driveways beside slabs among work needing no permit, but our resurfacing stays indoors, on garage, basement and shop slabs. Salt reaches a Greenlawn garage on car tires: the Town's stormwater plan says it maintains about 800 miles of public roads and begins sweeping their winter sand and salt in spring, so a season of it has dripped onto the apron first. Our Huntington floor coating data page gives NOAA's freezing-night counts for its Centerport station by month.

How far the repair goes depends on the concrete under the damage. A few spalls or popouts get cut out and filled; a slab scaled or dusting over most of the floor takes a polymer-modified resurfacer or a self-leveling topping on sound concrete; a hollow-sounding patch is a delamination, a skin NRMCA's CIP 20 puts at 1/8 to 1/4 inch. Re-Cap, Quikrete's resurfacer, takes people at 8 hours and cars at 24 by its sheet, and we say in writing which repairs will still show.
