How polishing works
Polishing is a mechanical process, not a coating. We use heavy planetary grinders fitted with diamond tooling, starting with coarse grits that flatten the surface and moving through progressively finer grits that refine it. Along the way, we apply a chemical densifier that soaks into the concrete and reacts to make the surface harder and less porous. The final passes produce a sheen ranging from a soft satin to a reflective gloss, depending on how far we polish.
Choosing an exposure level
How deep we grind determines how much aggregate shows. A cream finish keeps the top paste with little stone showing for a smooth, uniform look. Salt and pepper exposure reveals fine sand and small stones. Full aggregate exposure cuts deeper and shows larger stones for a terrazzo-like look. We test a small area first so you can see what your particular slab reveals.
Where it works well
Polished concrete is a favorite for retail stores, offices, warehouses, schools, breweries and restaurants because it is easy to clean and handles heavy foot and cart traffic. Homeowners choose it for basements, open-plan living spaces, modern builds and renovated older buildings. Downtown storefronts in brick buildings often have old slabs with patches and character that polishing turns into a feature rather than something to cover.
Benefits
- No coating to peel, chip or wear through
- High light reflectivity that brightens rooms
- Simple cleaning with a dust mop and auto scrubber
- Long life with occasional burnishing
- Works well with radiant floor heat
Stains and dyes
We can add color with penetrating dyes before final polishing. Earthy browns and grays suit offices and homes; brighter colors and logos work in retail. Dyes are absorbed into the concrete rather than sitting on top, so they do not peel. A guard sealer is applied at the end to add stain resistance.
Old slab realities
Polishing shows what is in the slab: patches, cracks, old drain lines, tile adhesive marks and color variation. Some of that can be filled or minimized, but it will not disappear completely. We walk the floor with you and explain what to expect. Many owners love the character; others prefer a coating. Either way you will know before work begins.
Polished concrete for new construction
If you are building, polished floors work best when planned early. We can talk with your builder about finishing the slab, protecting it during construction and timing the polishing after drywall and painting are complete. Planning ahead helps the final floor look its best.
Upkeep
Dust mop daily to remove grit, which is the main enemy of shine. Clean with a neutral cleaner, and for commercial floors use an auto scrubber with soft pads. Periodic burnishing restores gloss. Wipe acidic spills like vinegar, wine or soda quickly, because they can etch the surface even with a guard sealer.
Questions
Is polished concrete slippery?
When clean and dry, polished concrete usually has good grip. Water and dust reduce traction, as on any hard floor.
Can any slab be polished?
Most can. Very soft, damaged or heavily patched slabs may suit a coating better.
How long does it take?
Most rooms take a few days, depending on size and finish level.

Breweries, galleries and renovated mills
Renovated industrial buildings and downtown spaces are turning into taprooms, galleries and studios, and polished concrete suits them well. It handles spilled beer, rolling carts and crowds, and its sheen bounces light around rooms with tall ceilings. Old expansion joints and patch marks become part of the character of the space.
