Terrazzo Restoration FAQs

Grinding, crack repair and polishing terrazzo floors.

Terrazzo Grinding, Polishing & Sealing Services

Terrazzo is built to last for decades, but it dulls quickly once the surface loses its polish or picks up stains from years of foot traffic. Our terrazzo restoration for Chicago buildings starts with grinding down scratches and old wax buildup that's often layered over the original stone. Progressively finer grits bring the aggregate and binder back to an even, reflective surface, since uneven grinding is what leaves terrazzo looking patchy instead of uniform. Our terrazzo floor restoration across Chicago finishes with a densifier and sealer that protects against staining while keeping the natural shine intact. The final polish is what actually delivers the high-gloss finish terrazzo is known for and holds up when the grinding underneath was done correctly in the first place.

Commercial & Residential Terrazzo Restoration

Commercial buildings make up a large share of our terrazzo work, since lobbies, hallways, and hospital corridors were often poured in terrazzo decades ago and have rarely been maintained since. Our terrazzo polishing for Chicago businesses handles large square footage in sections, scheduled around operating hours to avoid disrupting foot traffic. Residential terrazzo is most common in older Chicago homes and vintage condo buildings, often original to the property and worth preserving rather than covering over. Our terrazzo cleaning across Chicago restores that original character without replacing a single tile. Whether it's a hospital hallway or a single condo entryway, the same grinding and sealing process applies, just scaled to the space.

Common questions about terrazzo restoration

Can you bring old terrazzo back to a high-gloss shine?

Yes. Terrazzo is essentially marble chips in a cement or epoxy matrix, so it polishes the way marble does. Grinding removes the worn surface and old coatings, and diamond polishing builds a genuine high-gloss finish from the stone itself rather than a wax layer that dulls within months.

Do you repair cracks and holes in terrazzo floors?

Yes. Cracks are stabilized and filled, holes and divots are patched with matching aggregate and matrix, and missing chips are replaced before the floor is ground so repairs blend in. Damaged or lifting brass divider strips are re-set. Repairs are part of every terrazzo floor restoration in Chicago we perform.

How often should terrazzo be professionally restored?

A properly ground and polished terrazzo floor typically holds its finish for many years with neutral cleaning. Busy commercial lobbies benefit from a light re-polish every one to three years, while residential floors go far longer. Terrazzo cleaning in Chicago with the right products avoids the need for frequent full restoration.

Can old terrazzo under carpet or tile be restored?

Almost always. Once the covering and adhesive are removed we grind the floor flat, fill cracks and divots with color-matched material, then hone and polish it back to a reflective finish. Vintage terrazzo often looks better than new.

How do you repair cracks in terrazzo?

Cracks are cleaned out, filled with a tinted epoxy or cement fill that matches the surrounding matrix and aggregate, and ground flush before the floor is polished. Structural cracks may be pinned first to keep them from reopening.

Is polished terrazzo slippery?

A properly diamond-polished terrazzo floor without topical wax meets standard slip-resistance guidelines when dry. We can also apply an anti-slip treatment in entries and commercial lobbies if requested.
