Honed concrete exterior slab

[stealman]

I have a covered exterior patio that has tile installed over it. The installation was not done well and the tiles are coming up from not having enough thinset under them. I can knock on them and hear how they are hollow.
I am looking for options on what to do. It's roughly 600 sq' so a tile installation is not going to be cheap. I am thinking remove the tiles and have the concrete slab ground and honed. How will this work out side? I'm assuming it would need a sealer of some sort?
I would like to hear opinions on doing this?
Thanks

Fa from an expert here but it sounds like you are just pulling up old tile and laying new tile popping the old tiles up shouldn’t be too hard since it sounds like they are already coming up. A six foot long steel bar with a flat edge on one end and a ball on the other end for your palm would keep you upright for most of the removal. It will probably knock loose a bunch of the mortar and grout. Whatever doesn’t come up. A rotary hammer set to impact only and a flat bit will get the rest.

Thanks. I'm not worried about removing the tiles. I am looking for thoughts and experience about a honed slab in a exterior application. It is covered with a roof and it is in Arizona.

Never heard of a honed slab.
Are you referring to a polished slab like Home Depot floors?

How a ground/polished slab turns out, is entirely dependent how the slab was poured and finished. Also, sometimes the grout will etch the concrete, and the old grount lines will show on the polished slab. I put up a steel building on an old loading dock a few years ago. We ground and polished the slab; one half looked awesome, the other half looked like ****. No reason you can't do this on an exterior slab, but it can be slippery if wet.

That's good to know about the grout lines showing through. I wonder if the best thing to do is take a few tiles off and spot grind a test section to see how it looks before commiting to the whole thing.
In regards to honed, I used that term because I'm thinking of a polished floor, but not shinny.
