Terrazzo Restoration in South St. Paul, Minnesota.

Some are. The historic stockyards district has industrial slabs with unusual contamination history that may need specialized prep. We assess on the estimate visit.

Yes, those slabs need full diamond grinding, polyurea crack fill, and often spalling repair. The polyurea system bonds reliably to clean substrate regardless of age.

About 50 minutes via I-94 then I-494. Batched with east-metro jobs.

Sealing is the less expensive of the two in nearly every case, because the labor is stripping and cleaning rather than multiple passes of diamond tooling, slurry extraction and dust containment. What moves our number is how much old finish has to come off, which on terrazzo is usually the bulk of the job. We walk the floor and give you a fixed written price before anything starts.

On a floor that is dulled by old wax rather than physically damaged, yes, and it is usually the part people are not expecting. The chips and the color are still there under the build-up. Stripping takes the gray film off and the coat that goes on top wets the surface and brings the depth back. Terrazzo that has been ground through, cracked, or patched with mismatched material is a different conversation and we will tell you that on the walk.

Yes. Terrazzo with deep damage, failed patches, lippage at the seams, or aggregate that has genuinely worn through needs material removed before anything goes on top. Sealing a floor in that condition locks the problem in. If that is what your floor needs, we will say so rather than quote the job we would rather do.

Foot traffic returns 4 to 5 hours after the coat goes down on the fast formula, 8 hours on the slower one. Corridors get done in sections so no route through the building is closed for a full day, and most of this work is scheduled overnight or over a break anyway.

That is when most of it happens. An empty building and dry winter air are both good for this work, and a two-week winter break is enough for a substantial amount of floor. Booking it takes some lead time, so the conversation usually happens a couple of months ahead of the break rather than the week before.

The matte finish tests at 0.9 dry coefficient of friction and the gloss at 0.51. Where a floor needs more, a traction additive is mixed into the coating, which raises the slip rating and the abrasion resistance at the same time. Entries, stair landings and anywhere that takes snowmelt usually get it.

Dust mop, then damp mop with water or a neutral cleaner, and an auto-scrubber with a microfiber pad on the large open runs. No burnishing, no polishing, and nothing that leaves an acrylic layer behind. The floor equipment a building keeps for terrazzo mostly stops being needed.
