What we do: epoxy & polished concrete
- Epoxy floor coatings — resin + hardener systems that bond to prepared concrete; residential, commercial & industrial; thickness from thin film up to thicker overlays/mortar. Also called concrete overlays / micro toppings.
- Decorative systems — color, flake/chip, quartz broadcast, metallic powders, terrazzo-style aggregate, logos/markings, stampable overlays.
- Performance systems — self-leveling / epoxy mortar for worn or heavy-duty slabs; slip-resistant textures; ESD / anti-static where needed.
- System stack (pro) — primer (moisture barrier / bond), epoxy build coats, clear urethane topcoat for durability & UV.
- Polished concrete — diamond grind + densify/harden multi-step process; matte to high-gloss classes; aggregate exposure grades (cream → large); stains/dyes & decorative cuts. Mechanical polish vs faster grind-and-seal (topical sealer; more reseal maintenance). Deep polish education: concrete polishing; commercial benefits: polished concrete floors.
Brief chooser: Worn, cracked, or chemical-heavy slabs often favor epoxy overlays; sound slabs wanting a permanent, low-build look often favor mechanical polish. Side-by-side education: polished concrete vs epoxy flooring.
How epoxy installation works
- Free consultation & estimate — Use case (garage, basement, shop, warehouse), system type (flake vs metallic vs mortar/self-level), slip needs, downtime. Start Instant Preliminary Estimate, then free on-site for a firm quote.
- Slab check — Almost any concrete can take epoxy if properly prepared; heavily cracked/unstable slabs may not qualify. Moisture and bond conditions drive primer choice.
- Prep (critical) — Grind to remove residue/coatings; remove dust and stains (prep is often the most time-consuming step).
- Primer — Seals concrete; moisture barrier; protects bond from bubbling/buckling.
- Epoxy coat(s) — Build coats; optional flake/quartz/metallic broadcast; mortar or self-level where specified (self-level poured/troweled, spiked rollers).
- Topcoat — Clear urethane for durability & UV.
- Cure & walkthrough — Traffic timing depends on product/system — confirmed on estimate.
Polished concrete process
- Estimate — Existing slab condition, desired gloss class, aggregate grade, stain/dye, mechanical vs grind-and-seal.
- Prep — Decontaminate; epoxy-fill joints/cracks/pits as needed; remove old coatings by grind.
- Grind & polish — Dry diamond method preferred (dust captured to machine); progressive grits to target sheen (Class 1 flat → Class 4 high gloss).
- Densify — Penetrating densifier hardens surface, reduces dusting, helps seal against moisture/stains.
- Optional color / cuts / topical — Stains/dyes, decorative saw cuts, optional stain guard or sealer. New concrete: do not polish/seal until fully cured (often 30–60 days) + moisture meter check.

Polished concrete floors & concrete polishing services
Polished concrete floors keep the slab itself as the finished surface — no thick resin overlay. Gemini Floor Services offers concrete polishing services for homes, basements, and commercial spaces in Brooklyn, NYC, and Long Island. Progressive diamond tooling, densifier, and optional stain or dye reach the sheen and aggregate look you want, from a soft matte to a higher gloss.
Mechanical polish suits sound slabs that already have character: lofts, retail floors, warehouses, and open-plan homes where a low-build look fits better than a coating. Grind-and-seal is a lighter path when schedule favors a topical seal over full multi-grit polish; it needs periodic reseal, which we explain on the estimate. For side-by-side education, see the epoxy vs polished concrete chooser on this page.
Polished concrete basements in Brooklyn
Brooklyn basements often sit on concrete that was never meant as a finished floor. When the slab is sound and moisture is under control, polished concrete can brighten a lower level without a coating film. We check moisture and patch needs first. If the slab is worn or heavily patched, an epoxy overlay may be the better recommendation — same crew, honest chooser. See our other Brooklyn flooring work by neighborhood.
Long Island polished concrete for businesses and homes follows the same diamond process from Freeport. Call (718) 690-3435 in Brooklyn or (516) 209-6998 in Nassau for a slab walk-through.
Timeline
Job-specific factors — prep, system layers or grit classes, square footage, and cure windows — change the schedule and are confirmed on estimate. We do not invent generic day counts.
| Scope | Guidance |
|---|---|
| Epoxy | Multi-layer system (primer / epoxy / topcoat); epoxy can take several days vs simpler polish — job-specific; confirm on estimate |
| Mechanical polish | Multi-step grind → densify → finer grits; schedule follows square footage, patching, grit class |
| Grind-and-seal | Faster / less expensive than full mechanical; needs periodic reseal |
Where epoxy & polish are used in Brooklyn
- Garages — Most common residential epoxy use; protects from liquids, salts, automotive fluids. Garage options overview: garage flooring (moisture caveat for coatings).
- Basements — On the epoxy / self-level use lists; slab moisture still drives prep/primer.
- Commercial / industrial — Warehouses, retail, kitchens, labs, showrooms, offices; mortar/self-level for heavy loads/chemicals. Polish + polished concrete floors: high-traffic commercial durability, light reflectance, low upkeep.
Garage epoxy flooring in Brooklyn & Long Island
Brooklyn and Long Island garages take real abuse — road salt, tire heat, oil drips, and wet tires tracked in from the street. Garage epoxy flooring turns a porous slab into a sealed, wipeable surface that stands up to that traffic. Gemini Floor Services installs residential garage epoxy from 229 Sumter St in Brooklyn and from Freeport at 220 N Columbus Ave, with Suffolk crews reachable at (631) 739-8353. We also work in Park Slope & Windsor Terrace. We also schedule garage jobs for Staten Island houses.
A typical garage system starts with grinding the slab so the resin can bond, then primer, epoxy build coats, and a clear urethane topcoat. Decorative flake broadcast is a popular look for home garages: it hides small stains, adds grip underfoot, and reads finished rather than utilitarian. Metallic and solid-color looks can also be discussed when you want a finished feel instead of flake. For heavier wear or uneven slabs, we may recommend a thicker epoxy mortar or self-leveling build — scoped on the on-site visit.
Moisture and slab condition matter. If the garage slab is new, still curing, or shows active moisture, we say so before coating. Sound, prepared concrete is the right candidate. Flake garage floors on Long Island and Brooklyn share the same prep discipline; we do not treat the garage as a DIY paint job. If a leak or move date forces the schedule, ask about timing when you call (718) 690-3435 or (516) 209-6998.
Epoxy vs polished concrete (quick chooser)

What affects the cost
The live Instant Preliminary Estimate is a preliminary guide, and the final quote comes after a free on-site measure. The epoxy system (standard coat, flake or metallic, quartz, or self-level/mortar) or polished path (mechanical multi-grit vs grind-and-seal, plus gloss and aggregate grade), along with primer, densifier, topcoat and optional stain-guard selections, shapes the quote. Square footage and number of rooms or zones, slab condition (cracks, coatings removal, leveling, moisture mitigation), logos or multi-color designs, and access, downtime windows and cure time in occupied commercial spaces also matter.

Frequently asked questions
What’s the difference between epoxy flooring and polished concrete?
Epoxy is a resin coating system built over a prepared concrete slab — primer, epoxy coats, and usually a clear topcoat, with optional flake, quartz, or metallic designs. Polished concrete is the existing slab itself, diamond-ground and densified to a chosen gloss — no thick coating layer. Worn or chemical-heavy floors often lean epoxy; sound slabs wanting a permanent low-build look often lean polish. See polished concrete vs epoxy flooring and concrete polishing.
Can you epoxy a garage or basement in Brooklyn or on Long Island?
Yes — garages are the most common residential epoxy use (fluids, salts, liquids) and basements are on the epoxy / self-level use lists. Moisture in the slab still has to be checked; high moisture can block coatings (garage options page). We’ll confirm prep and primer on-site. Call Brooklyn (718) 690-3435 or Nassau (516) 209-6998.
Do you do flake, metallic, and commercial epoxy systems?
Yes. Systems include decorative flake and glitter, epoxy quartz, metallic powders, self-leveling and epoxy mortar for heavy-duty / industrial slabs, stampable overlays, and ESD/anti-static where static is a hazard. Commercial and industrial spaces are in scope alongside homes.
Is polished concrete only for warehouses — or homes too?
Once mostly commercial/industrial, polished concrete is now also residential when the slab qualifies. Mechanical diamond polish with densifier is the durable path; grind-and-seal is faster and lighter but needs periodic reseal. Commercial benefit write-up: polished concrete floors. Full process: concrete polishing.
How long does epoxy or polished concrete take — and how is it quoted?
Schedule depends on prep, system layers or grit classes, square footage, and cure windows — epoxy can be a multi-day install versus simpler polish paths. We do not publish per-square-foot rates on this page. Use Instant Preliminary Estimate for a preliminary guide, then free on-site measure for a firm quote.
Are you licensed and insured for co-ops and commercial jobs?
Yes. We’re family-owned — not a franchise — licensed and insured, with 30+ years and a 5-year workmanship warranty on our work as stated on the job. We can provide insurance paperwork buildings and landlords ask for. Brooklyn: 229 Sumter St · (718) 690-3435. Freeport: 220 N Columbus · (516) 209-6998. LI: (631) 739-8353.
What garage epoxy system works best for a Brooklyn or Nassau driveway garage?
Most home garages do well with a flake broadcast over primed epoxy and a clear topcoat — durable, slip-aware underfoot, and easier to keep looking sharp than bare concrete. Metallic or solid colors suit spaces that want a finished, high-end look. We confirm flake size, slip texture, and moisture conditions on site before we lock the system.
Can you coat a polished concrete garage floor later with epoxy — or the other way around?
They are different finishes. Polished concrete is the slab itself, diamond-ground and densified. Epoxy is a bonded coating. Moving from one to the other means full prep (often grinding off the prior finish). We recommend choosing one path for the garage up front; see our epoxy vs polished concrete chooser on this page.
Do you install garage epoxy on Long Island as well as Brooklyn?
Yes. Brooklyn jobs stage from 229 Sumter St, (718) 690-3435. Nassau and nearby Suffolk jobs stage from Freeport, (516) 209-6998, with Suffolk at (631) 739-8353. Flake garage floors are a regular residential request on both sides of the East River.
What are concrete polishing services — is it the same as sealing concrete?
Concrete polishing services mean grinding and densifying the slab with diamond tooling to a chosen gloss class. A simple sealer or grind-and-seal is a lighter topical path and needs more reseal care. Full mechanical polish is the permanent low-build option for sound slabs.
Diamond polished concrete in NYC — do you work occupied buildings?
Yes when building rules allow grind work. We plan dust capture at the machine, work hours, and hallway protection. Brooklyn HQ at 229 Sumter St helps with NYC access coordination; paperwork for insurance is available on request.
