Polished Concrete in Wynwood, Miami for Galleries & Restaurants
Wynwood floors have usually lived several lives before you get them: garment-district warehouse, storage bay, then gallery, taproom or showroom. That history shows up as paint, mastic, saw cuts and patches, and it decides which floor will work. We grind and polish existing slabs into durable polished concrete, and where a brewhouse or kitchen sees hot water and spills, we install seamless coatings built for that abuse. Our crews cover the whole urban core from our Miami service area, scheduling around openings, events and Art Week.
The Short Answer
Polished concrete in Wynwood means grinding an existing warehouse or gallery slab with progressively finer diamonds, hardening it with a densifier and burnishing it to a matte, satin or high-gloss sheen. Polished concrete typically runs about $3 to $8 per square foot, and most storefronts or galleries are done in two to four days. Art of Coating Miami tests the slab, repairs old joints and patches first, and recommends urethane cement where brewery or kitchen washdown demands more than a polish.

Wynwood Property Types and How Floors Get Used
Wynwood is a mix of low-rise warehouses converted to galleries, breweries, restaurants, boutiques and creative offices, plus newer mixed-use buildings with ground-floor retail. Each use loads a floor differently. Galleries want a quiet, even surface that does not compete with the art and can take rolling crates and lifts during install weeks. Retail and showrooms get heavy foot traffic carried in from painted sidewalks, along with sand and grit. Creative offices want a clean, low-maintenance look that suits exposed ceilings and ductwork. Breweries and restaurants are the hardest case, with hot washdown, sugars, oils, cleaning chemicals and constant wet traffic. We walk the space with you, note where traffic concentrates and where liquids land, and then decide whether a polish, a coating or a combination of the two will hold up best.
Old Warehouse Slabs and Wynwood's Humid Climate
Most Wynwood buildings sit on older slabs-on-grade that have been cut for plumbing, patched after tenant changes and covered with paint, tile adhesive or carpet glue. Expect hairline cracks, uneven control joints, spalled edges at loading doors and patches that polish to a different color than the original concrete. Miami's humidity and shallow groundwater add moisture vapor coming up through the slab. Polished concrete tolerates that well because it is not a film that can blister. Coatings are a different story: before any epoxy or urethane goes down, we run ASTM F1869 calcium chloride or ASTM F2170 relative humidity tests and add a vapor-mitigating primer when readings call for it. We also fill joints with semi-rigid filler where carts and pallet jacks roll, so edges do not chip under wheels.
Recommended Floor Systems for Wynwood Businesses
For galleries, offices and retail, a mechanically polished floor is usually the right base: diamond-ground, densified, then polished to a satin or high-gloss sheen and protected with a stain guard. If you want more color, dyes can be added during the polish to warm up gray concrete or hide uneven patches. Where the original slab is too damaged to polish evenly, a decorative coating such as metallic epoxy or a microcement overlay gives a designed look instead. Breweries, kitchens and back-of-house areas need more protection than any polish provides, so we install urethane cement that handles hot washdown, thermal shock and food acids, with slip-resistant aggregate and coved base at walls. Front-of-house dining rooms often pair a polished floor in public areas with a coated kitchen line. Our restaurant flooring work follows that split approach.
Our Wynwood Polished Concrete Installation Process
Every job starts by removing what is already there. We strip paint, adhesives and old sealers with diamond tooling, then grind the slab flat enough to polish evenly, working through progressively finer metal-bond and resin-bond diamonds. Cracks and saw cuts are filled with color-matched repair material, and spalled joint edges are rebuilt before polishing so they do not show as dark lines. A lithium or sodium silicate densifier hardens the surface partway through, the floor is polished to your chosen sheen, and a penetrating guard finishes it to resist stains from coffee, wine and cleaning products. Dust is captured with vacuum-attached grinders, which matters in occupied buildings and galleries with art on the walls. For coated areas, we profile the slab to the ICRI concrete surface profile listed on the manufacturer's technical data sheet before priming.
Polished Concrete Costs for Wynwood Spaces
Polished concrete in Wynwood generally falls around $3 to $8 per square foot. The low end fits a sound slab that needs a light grind and a satin finish; the high end covers heavy removal of glue or paint, extensive crack and joint repair, dyes and a high-gloss polish. Commercial coatings for kitchens, breweries and back-of-house areas typically run about $4 to $12 per square foot, and urethane cement sits above that range because of its thickness and thermal resistance. Metallic epoxy for a feature showroom floor runs roughly $8 to $15 per square foot. We quote after a free on-site assessment and provide a written, itemized estimate showing removal, repairs, finish level and any moisture mitigation as separate lines.
Day by Day: A Wynwood Floor Project
Day one usually covers protection and removal: we mask walls, doors and fixtures, then grind off coatings and adhesives. Day two is repair and the coarse-to-medium grind, followed by densifier. Day three is the fine polish and guard, and larger warehouses or heavily patched slabs may add a day or two. Coated kitchens and brewhouses typically need two to three days including cure time before equipment returns. To prepare, clear the floor completely, including racks, art, displays and furniture. Have plumbing and electrical trades finish floor penetrations first. Tell your landlord or property manager the dates and confirm access to water and 208/240-volt power for grinders. Most retail and restaurant owners schedule us between seasons or right before a reopening so the floor is finished on time.
Polished Concrete or Coating in Wynwood?
Polished concrete fits when the slab is structurally sound, the space stays mostly dry and you want a low-maintenance surface that will not peel: galleries, offices, retail, showrooms and dining rooms. It reflects light well, which helps in deep warehouse floor plans, and it only needs periodic burnishing rather than recoating. A coating fits better when the floor sees standing liquids, hot washdown, chemicals or food acids, as in brewhouses, commercial kitchens and bar wells, or when the slab is so patched that a polish would look blotchy. Some owners want a specific color or a seamless decorative finish that raw concrete cannot deliver. Our commercial flooring options cover those cases.
