Epoxy Flooring in Key Biscayne
Key Biscayne is an island village wrapped in salt water, oceanfront condo towers, single-family estates, and the parks at Crandon and Bill Baggs at either end. 343 Epoxy installs floors engineered for that environment: condo parking decks, estate garages, pool decks, and patios built to hold their finish through constant salt air.
An Island Built on Salt and Sun
Key Biscayne is an island, and everything about flooring here starts with that fact. There is no part of the village that isn’t close to salt water, so chloride and humidity are the constant enemy of any coating. A parking deck, a garage, a pool deck, if it isn’t spec’d for marine exposure, it fails fast. We install systems engineered specifically for that.
The housing splits between oceanfront condo towers and single-family estates. The towers need parking-deck, valet, and storage coatings that are durable and clean; the estates want finish-quality metallic and flake garages and decorative patios. Pool decks are nearly universal here, and they take the worst of it, sun, salt, and constant splash, so we use textured, slip-rated coatings built for that exact punishment.
Getting onto the island and working cleanly matters too. The Rickenbacker Causeway is the only way in, and the village is dense and particular about how contractors operate. We plan logistics, keep sites contained, and handle condo-association and village requirements so the job goes smoothly. The payoff is a floor that actually survives island conditions.
Salt does its damage in two places. On the surface it leaves a film that has to be washed off and profiled away before any primer goes down, or the coating bonds to the salt instead of the concrete. Inside an older slab it can rust the steel, which shows up as cracks and spalls that need repair first. Zach checks for both, and every floor carries a 5-year warranty on materials and installation.
Both Ends of the Village
Oceanfront Condo Towers
The luxury towers along the ocean and the bay. Parking-deck, valet, and storage coatings engineered for marine exposure, durable, clean systems that resist salt and constant traffic.
Village Estates
The single-family homes throughout the village interior. Metallic and premium flake garages and decorative patio finishes, finish-first work with prep built for the island environment.
Pool Decks & Patios
Nearly universal on the island and the hardest-working surfaces here. Textured, slip-rated coatings built for sun, salt, and constant splash, cool underfoot, grippy when wet.
Crandon & Commercial
The village commercial core and the properties near Crandon Boulevard. Retail, restaurant, and office floors, decorative finishes up front, urethane cement for kitchens.
Marine-Grade From Primer to Topcoat
Every system below is available throughout Key Biscayne and across Miami-Dade County. Pick by use case. We’ll confirm the right spec at the on-site visit.
Garage & Flake Epoxy
The Key Biscayne default. Decorative chip blends over a 100% solids epoxy base, sealed with an aliphatic urethane topcoat that handles hot tires and Florida heat. On the island the salt film gets washed off before the grind, so the base coat bonds to concrete and not to residue. Most garage floors take one to two days, depending on the system and what the slab needs.
Pool Deck & Patio
Textured, slip-rated coatings for the patios and pool decks across Key Biscayne. Stays cooler underfoot than bare concrete and grippy when wet, built for sun-exposed, splash-zone surfaces.
Metallic Epoxy
Premium decorative finish for showrooms, collector-car bays, and high-end garages. Here it belongs indoors, in an estate garage kept shut against blowing sand and spray. The color samples ride across the causeway with us so you can choose in your own light.
Commercial · Quartz · Urethane
Key Biscayne commercial floors get spec’d coatings: high-build commercial epoxy for retail and offices, broadcast quartz for slip-rated kitchens and labs, urethane cement for any floor that gets steam-cleaned daily.
