Epoxy Floors for the Sunshine City Coated in the Window That Holds

It moves the work to the right hours. Relative humidity here averages roughly 88% at 7 a.m. and falls to about 57% by late afternoon, while manufacturer data sheets stop you at around 85% relative humidity. Above that line epoxy can amine-blush — the waxy film that keeps the next coat from bonding. The same sheets ask for a slab at least 5°F above the dew point. So the binding constraint here is the morning, not the afternoon thunderstorm, and we read a hygrometer before we open a kit. The Gulf and Atlantic sea breezes also collide somewhere over the peninsula on summer afternoons, and on the days that line sets up over Pinellas a working window can close inside an hour. The long version →

Flake runs about $5 to $9 per square foot, solid color $4 to $7, metallic $9 to $14. A 400 to 500 square foot two-car garage with a full flake-and-polyaspartic build-up — moisture test and diamond-grind prep included — typically lands between $4,000 and $5,500. If the slab reads wet, a vapor-barrier primer adds roughly $1.50 to $3 per square foot, and you get that number before you sign rather than after we start grinding. Line-by-line pricing →

Almost always moisture vapor pushing up through the slab. Two thirds of this city's housing — 67.7% of all units in the 2024 American Community Survey — was built before 1980, when under-slab vapor retarders were thin, patchy, or simply never installed. Those slabs can push past 3 lbs per 1,000 sq ft per 24 hours, which is where delamination risk climbs. So we measure first: ASTM F1869 calcium chloride, or ASTM F2170 in-situ relative humidity probes when the slab calls for it. High reading, the floor gets a vapor-barrier primer. Low reading, you do not pay for one.

Less a wrong month than a wrong hour. June through September delivers roughly two thirds of the year's rain, so summer slabs read wetter and the morning humidity window is tighter. November through April is the easy stretch, and it books out first. Either way we test the slab that day, work the drier half of the afternoon, and finish in a humidity-rated polyaspartic topcoat instead of waiting on slow-curing epoxy alone.

Ten to thirty years in a home, five to twenty in a shop or warehouse taking forklift and pallet traffic. What decides it is everything that happened before the first coat: a slab that was tested and, where the reading called for it, primed against vapor, plus a UV-stable topcoat that will not amber under Sunshine City sun. Floors that skip both are the ones peeling inside a year. If yours is already lifting →

Pinellas County, end to end. Tarpon Springs and Palm Harbor at the north end; Dunedin, Clearwater, Largo, Seminole, Pinellas Park and East Lake through the middle; Gulfport, St. Pete Beach, Treasure Island and Tierra Verde out on the water. Same crew, same pricing, no travel surcharge inside the county. Every area we cover →

Three questions do most of the work. Does the estimate come after a slab moisture test, or before one? Are the prices published, or quote-only? And is the person who measures your garage the person who grinds it? In a city where two of every three homes predate 1980, that moisture reading is the whole ballgame. Concept Epoxy St Pete answers yes to all three: a free ASTM test with a written St. Petersburg Slab Report, ranges published on this site, and Duane on the floor.
