Stone care and polishing
We restore, polish and protect natural stone, terrazzo and architectural concrete across Bay Area facilities. From foundation grinding and diamond honing to penetrating sealers and daily neutral-cleaner upkeep, the written scope sets the finish and schedule for every surface.
What we look for
On the walk, across the stone and slab.
- Surface and mineral class
Marble, limestone, travertine, granite, terrazzo or exposed structural concrete: each material takes its own diamond grit sequence, chemistry and sealer.
- Lippage and uneven joints
Where adjacent tiles or slab edges sit uneven by more than one-eighth inch, we note where foundation grinding is needed to flatten the floor before honing.
- Etching, scratches and wear paths
Dull traffic lanes, acid etches, deep scratches, pitting and worn coatings that require mechanical diamond refinement rather than topical wax.
- Slurry, dust and edge protection
Wet vacuum pickup, shroud extraction, baseboard masking, elevator thresholds and adjacent carpet or wood transitions that need protection during grinding.
- Target sheen and slip resistance
Whether the room calls for a flat matte, a low-sheen satin or a high-clarity reflective polish, matched to the lighting and foot traffic.
- Daily maintenance chemistry
Neutral stone cleaners, microfiber dust mopping and entry walk-off mat placement, keeping acidic, vinegar, lemon, ammonia and abrasive products off the floor.
Stone and concrete programs
Three programs, one surface team.
Whether your building has a veined marble lobby, a limestone staircase or a concrete warehouse aisle, we scope the restoration and the ongoing maintenance together.
Natural stone restoration
Diamond honing, etch and scratch removal, and sealing for marble and stone.
Concrete floor polishing
Mechanical grinding, honing and polishing for dense, bright concrete slabs.
Scheduled floor care
Neutral microfiber care, scrubbing and periodic re-polishing on a schedule.
The refinishing process
From rough surface to a sealed, reflective finish.
Stone and concrete refinishing is a progressive mechanical process. Each stage uses finer diamond abrasives to close the pore structure before protection is applied.
Foundation grinding
When tiles or slabs have lippage exceeding one-eighth inch or failed coatings, heavy metal-bond diamonds level the uneven edges and flatten the surface.
Coarse grinding
Coarse diamond passes remove deep scratches, surface stains, pitting and stubborn residue, resetting the floor to a clean, uniform plane.
Progressive diamond honing
Medium and fine resin-bond diamonds smooth the scratch pattern from grinding, erase acid etching and establish a consistent matte or satin sheen.
Mechanical polishing
Fine polishing abrasives and pads bring marble, limestone, terrazzo and densified concrete to the specified satin or mirror-like clarity.
Sealing and ongoing care
Penetrating sealers guard against water and oil intrusion, followed by walk-off mats, microfiber dusting and pH-neutral stone cleaner on schedule.

Questions about stone care
How do we maintain stone and polished concrete between restorations?
We follow a four-part care system: seal with a penetrating protector, prevent grit damage with entrance mats and furniture pads, clean with microfiber pads and pH-neutral cleaner, and restore high-traffic lanes with periodic diamond maintenance.
Which cleaning products should never touch natural stone?
Never use acidic cleaners, vinegar, lemon juice, ammonia or abrasive powders and scrub pads on marble, limestone, travertine or terrazzo. They etch calcium-based stone and strip penetrating sealers.
Can you grind and polish floors while our building is occupied?
Yes. We schedule stone restoration and concrete grinding in phased night or weekend windows, using wet slurry collection and HEPA dust extraction with masked thresholds.
