In over my head, replacing shower floor tiles

Plan was to regrout shower tile floor 3 x 3 tiles. Got the grout out, but few pieces had chipped edges. Aaargh!! Decided to remove tiles. Not too bad. Now the base is uneven from the thin-set and a few places the black layer (I assume vapor barrier) came off too. The house is 13 yrs old. What should I do next?? Any tool recommendations appreciated too.

Planning on mosaic tile.

Using a stiff 3" putty knife like a chisel, and a hamner knock down any high spots. Then skim coat with modified thinset to smooth everything out. Let it set up overnight and then tile over that. You are fine, you are looking at a mudbed that should be fine. The moisture layer should be under the cement.

Use a modified thinset from a powder not a premixed one (mastic) as they are not rated for wet locations.

I am familiar with thinset. Is modified thinset same as "fortified thinset"?

Also, what is that black layer? Almost looks like something used to seal roof??

THanks

Yes fortified is modified.

That black membrane is your 'shower pan' and needs to be replaced to maintain its integrity. Could be a product such as these Merkrete Hydro Guard products.
