Our school is in West Texas and our terrazzo has cracked in a few areas from ground shifting. On the low side of the cracks the burnisher misses the floor surface and the finish is starting to discolor. We are using a hi-solids, alkaline based finish on the floor. Can anyone suggest methods to get those small missed areas shined up with the rest of the floor? |

If the ground is continuing to shift, you might as well live with the cracks and stains. But if it has stabilized, you can regrind the terrazzo.

How big of an arris does the floor have at the crack? If it's offset anywhere close to 1/8 of an inch, grinding may not be a great option. Typically epoxy terrazzo is only about 3/16 inch thick. You may want to get in touch with your applicator (presuming the ground is no longer shifting) and apply additional epoxy at the crack before grinding. I'd also cut in a joint, just in case. |

I would suggest you contact the NTMA and find out what their recommendations are. You should also know what type of terrazzo it is. |
