    Terrazzo repair is best left to the professionals. They can match the granite and marble chips for a flawless repair. I have seen some bad patch jobs even good tile workers have done that didn't know anything about terrazzo.

    Agree only a good Terrazzo job is worth the effort. A bad or unexperianced execution always shows an will make you redo the floor in the end anyways. I know from my own experiance that just a small hole like yours could cost a fortune but after I have been through it I am still thinking it was the right decision to conserve a piece of history here.

    First, I would use a utility knife and carefully cut out the damaged ares as they are such eyesores, i could never live with them a day longer. Then I would paint the spots just to make them less noticeable. Match the base color, them speckle them with marker or cheap nail polish colors. If they still and out too much, put small items on/in front of them. Then you will have to wait until the terrazzo guys get free, Get on their waiting list, this is no DIY repair.

    This is what a tile guy I know did for a temporary fix. He cleaned up the area, filled it in with concrete. Once it was dry, he painted a layer of white epoxy over the concrete. When that was dry, he proceeded to paint in the different granular stones in, let that dry and coated it with waterproof poly. His workers said it looked terrible and the homeowner would hate it. He said they all love it. The homeowner hated it. But this would be good for a temporary fix and you may surprise yourself and love it.

    Real terrazzo is a concrete mixture with a blend of different colored stones to give different colored terrazzo. Color selection by % of each colored pebble. After poured/ troweled/ set, the surface is ground to flatten and expose the stones. Your pic by the (shower/ tub unit?) looks more like a sheet vinyl flooring w/ rolled cove base? Is yours a concrete product? You also need to find/ cure the source of your water leaks?

      @Danielle M Unless you can find someone with a lot of experience, they will need to do samples and grind them out, in order to get the proper proportions of each color, or it will always look like a "mismatched patch". (From memory) the colored stones can be bought in smaller bags (by color) for repair jobs, and I imagine that the original installation big jobs were done by crews w/ a lot of experience, LOL.... but it was easy, once you knew the proportions for the job, and had the proper materials/ colors... like baking a cake...

    I agree with thenne1713 that you need to find out the source of water leak. The first picture looks like maybe mold even under tile on wall. Don't mean to be disrespectful, but that probably should be your first priority. Could save you headaches later on. Good luck getting all repairs done well and reasonable.

      @Danielle M And Bob Weldon suggested using drywall spackling, which is similar to plaster compounds. Won't hold, won't last, will break down!

    A floor buffing machine with a 3M scrubbing pad and any good quality floor cleaner will remove the stains and polish the stone. Start with Red pad to remove the built up crud then follow using white polishing pad. Wax the floor and it will look good as new.

    Leave this to a professional! I have a friend who just had her Terrazzo redone and it looks like brand new. I know you are probably anxious to get it done but get on the list and wait it out. You'll be glad you did. Once it is redone it will last for many years.

    I grew up with Terrazzo floors. Normal upkeep is damp mop and strip & rewax twice a year. However, your damages need professional help. When done correctly there should only be minimal difference in original & new. Good luck. send pic of new floor

    Does anyone have experience w a terrazzo floor with seashells and bits of colored glass instead of rocks? I've seen this at a restaurant at their outdoor dining area and it was just beautiful. And there were no rough edges from the shells or glass - I even felt it w my hand- totally smooth as I'd like to do it around our pool soon. I'd really like for it to be a DIY but will leave it to the pros. Altho I will let my pottery expert friend help me make a few dozen tiles w same shells and glass to use as decorative tiles around the edge of the pool. I know this might sound gross but I've also seen it with just shells in beach bathrooms. The shells are so beautiful because some of them are sanded down and the very pretty inside cuts of the shells are visible. Anyone have any experience with this?
