Commercial Terrazzo Restoration & Polishing

Terrazzo is built to last a century, and most of it in schools, courthouses, and lobbies is hiding under decades of yellowed wax. Modern terrazzo care doesn't wax it. We grind, hone, polish, and seal it to bring back its natural, durable, mirror-like shine.

Quick answerTerrazzo is restored by diamond grinding, honing, and polishing, then sealed, never waxed. We remove old wax buildup, refine the surface through grit stages, and bring up a natural gloss that lasts. Maintained terrazzo needs only routine neutral cleaning and occasional re-polishing, no recurring strip-and-wax.

How terrazzo is restored

Cement vs. epoxy terrazzo, and sheen levels

Traditional terrazzo uses a cement matrix; modern terrazzo often uses a thinner epoxy matrix. Both are restored by grinding and polishing, with the approach tuned to the matrix and the aggregate. How far the polishing goes sets the sheen.

Should terrazzo be waxed?

Generally no. Old maintenance programs waxed terrazzo, which yellows, dulls, and traps soil. Polished and sealed terrazzo looks better, lasts longer, and is easier to maintain. If your terrazzo is currently waxed, we remove it and restore the natural finish. See sealing vs. waxing.

Common terrazzo problems, and fixes

Keeping it on a program

Maintained terrazzo needs only neutral cleaning and occasional re-polishing. A maintenance program keeps the polish up and the seal intact so it never slides back into a costly full restoration.

Questions

Should terrazzo be waxed or polished?

Polished. Diamond polishing produces a durable natural shine; wax yellows, dulls, and traps dirt. Old wax can be removed and the floor restored.

Can old, neglected terrazzo be restored?

Almost always. Grinding and honing remove decades of wax, stains, scratches, and etching and bring the floor back.

How do you maintain polished terrazzo?

Routine neutral-cleaner mopping or auto-scrubbing and occasional re-polishing, with no recurring strip-and-wax.

What's the difference between cement and epoxy terrazzo?

Cement terrazzo is the traditional, thicker system; epoxy terrazzo uses a thinner resin matrix. Both are restored by grinding and polishing.

Does terrazzo need to be sealed?

Yes. A penetrating sealer helps the polished surface resist staining, since the matrix and stone are somewhat porous.

How long does terrazzo last?

Properly maintained, terrazzo can last the life of the building, often many decades, which is why restoring it usually beats replacing it.
