Regardless of what you find, if it's just concrete, once you grind it with the aggregate exposed it will resemble terrazzo. Easy!

Fortunately, the client simply wants to have it ground flat with the existing floor regardless whether it's concrete or terrazzo. They are not interested in matching the area to the existing terrazzo if it is simply concrete.

So I just need some guidance on chipping away or grinding it before restoring the terrazzo in the same area.

Thanks for the input.

We do quite a few of these type jobs-You may find Terrazzo under that patch but I doubt it.
If you do-certainly follow Rons good advice.
If you don't-
You can take a small cut of the terrazzo(2"x2") and send it off to one of the terrazzo manufacturers.
If you measure the square footage they can tell you how much you will need to fill those spaces.
You can mix the fill by hand and then carefully grind it down to match the existing terrazzo.
Sounds easy-but it can be quite involved-and you will need some tooling to help you.
Kevin may chime in-he become quite adept at the technique himself.
He may have chuckled when he read Sounds easy!

Blain,

I would suggest that you try using a demo hammer with a wide tip blade and attack this from the side. With luck the concrete will pop up doing little damage to the terrazzo which may be underneath. This will significantly reduce the time to grind this area. Once most of the concrete is removed then start the grinding with a 70 grit metal bond. If the demo hammer causes some of the material to pop out underneath and it is terrazzo there you can mix a knife grade epoxy, add color to match and fill any pits or holes. Go get it! Feel free to call me with any questions. Ron Moore 301.602.2307 cell.

I've got a terrazzo floor restoration on a remodeled building. During the remodel, 4 pillars were removed, revealing a rough concrete surface that may or may not be overlaid on terrazzo. These areas are slightly higher than the terrazzo floor and each one is approximately 2 sq ft. I'm looking for guidance on what to grind with, before 50 grit diamond resins.

Thanks.
