Does your book recommend muriatic acid on the concrete for all
installations, or only for special conditions? What concentration?
I have used muriatic once, on concrete, outdoors, per label, in
preparation for sealing a deck. It is NOT something I would even
consider using inside my home.
That was my take on it. But I tested a few square feet on
basement floor. Not for me, and I got no wife, no kids.
Much less dangerous outdoors (if you stay down-wind).
Do they still tile etc basement floors in new houses?
Do they first treat with acid? My guess is "Not".
Sounds like the OP needs an experienced flooring
guy for a consult. Match the right adhesive with
his floor. I just went out and bought name-brand
adhesive years ago and regretted it.

Update on old thread:
Turns out the thinset I bought (MAPEI) says that acid etching is "not
recommended". I've found the same recommendation (or non-
recommendation) on similar products. My tiling book information
