Polished concrete, grind & seal, and stain & seal — the slab you already own, finished into the most striking floor in the house.
Sunrooms, basements, living areas, and whole modern homes — the slab under your feet can be the finished floor. Here's how.
More and more Lowcountry homeowners are skipping tile, LVP, and carpet entirely and finishing the concrete that's already there. Done right, an interior concrete floor is seamless, allergen-free, cool in the summer, nearly indestructible, and unlike anything else on the street. There's no grout to scrub, no planks to buckle in our humidity, and nothing to replace in ten years.
We install three interior finishes, and the right one depends on the look you're after and the condition of your slab. Polished concrete grinds and hones the slab itself to a stone-like shine — no coating at all. Grind & seal grinds the slab smooth and caps it with a clear protective sealer. Stain & seal adds rich, translucent color before sealing, for floors with warmth and character. All three start the same way: diamond grinding with our 20–30 inch propane grinders and dust-free HEPA extraction — your house stays clean, we promise.
The slab itself, mechanically ground and honed through progressively finer diamonds until it shines — hardened along the way with a densifier. No coating, nothing to peel, ever. Choose satin, semi-gloss, or a high-gloss mirror finish.
The slab is ground smooth and clean, hardened with a densifier, then sealed under clear coats of urethane or epoxy. You keep the natural, industrial-chic concrete look — swirls, aggregate, character and all — with a protective film on top.
Translucent color — earthy acid-stain marbling or clean, consistent water-based tones — worked into the ground slab, then locked under a clear sealer. Every stained floor is one of a kind, with depth you can't get from any manufactured product.
Different destinations, same disciplined starting point: diamonds, dust extraction, and a properly densified slab.
Polishing is a purely mechanical process. We grind the slab with coarse metal-bond diamonds to open it up, apply a lithium silicate densifier — a penetrating liquid that reacts inside the concrete and hardens the surface dramatically — then hone and polish through finer and finer resin-bond diamonds until the floor reaches your chosen sheen. Satin stops around 400 grit, semi-gloss around 800, and high gloss runs to 1,500–3,000 for a true mirror. A penetrating stain guard is burnished in at the end to resist spills.
We grind the slab smooth, densify it, then apply clear film-forming sealers — typically a urethane for interiors, chosen for wear resistance and a beautiful, even sheen from matte to gloss. The concrete's natural character stays on full display, but now it's dust-proof, stain-resistant, and easy to mop.
Reactive acid stains chemically marry with the minerals in your slab, producing marbled, variegated earth tones that are permanent and impossible to replicate. Water-based stains offer a broader, more consistent palette — from soft neutrals to bold statements. Either way, the color is sealed beneath the same premium clear coats as a grind & seal floor.
Polished Concrete — What Makes the Shine
Grind & Seal / Stain & Seal — The Build
From a soft, honed satin to a showroom mirror — the finish level is a choice, not a coincidence.
| Finish Level | Polished Grit | The Look | Feels Like |
|---|---|---|---|
| Satin | Up to 400 grit | Soft, low-sheen glow — hides dust and fine scratches best | Relaxed, organic, farmhouse-modern |
| Semi-Gloss | Up to 800 grit | Clear reflection with a gentle depth — our most popular interior level | Clean, bright, effortlessly upscale |
| High Gloss | 1,500–3,000 grit | Mirror-like clarity that bounces light through the whole room | Bold, dramatic, gallery-grade |
Sealed finishes (grind & seal, stain & seal) offer the same range through the sealer itself — matte, satin, or gloss urethane topcoats.
We'll grind a test spot, walk you through sheen and color samples, and give you a straight answer on what your concrete can do.

Interior work demands respect for the home around it. Our propane grinders run clean with no cords or fumes to manage, and every machine is tethered to an SVX-series HEPA vacuum that captures dust at the source — no film of concrete dust on the baseboards, no cleanup marathon after we leave. Furniture protection, sealed doorways, and tidy job sites are standard practice.
Our 20–30 inch propane planetary diamond grinders profile the entire slab evenly — no cords, no missed spots, no shortcuts. Every floor is mechanically ground to the correct concrete surface profile (CSP) for the system going down on top of it.
Our SVX-series industrial HEPA vacuums connect directly to the grinders, capturing dust at the source. Your home or business stays clean, and the slab is left spotless and ready to bond.
Coastal Georgia slabs carry moisture. We test every floor for moisture vapor transmission before a drop of product goes down — and apply a dedicated moisture vapor barrier when the readings call for it.
Cracks, spalls, and pitting get patched with fast-setting repair mortars and ground flush. Expansion joints are honored so slab movement never telegraphs through your new floor.
Most interior floors take two to four days depending on square footage and finish level — and we treat your home like our own the whole way.
We evaluate the slab, grind a sample spot, and confirm the finish it can support.
Propane grinders with HEPA extraction level and open the slab, dust-free.
Cracks and pits are patched, then lithium silicate densifier hardens the surface.
