I was all set to tile my basement floor. I ripped up the old glued-down
carpet and got off > 80% of the adhesive residue by renting a floor
I thought I was good to go, but I read on the thinset directions that
water should not "bead up" on the concrete. This is to determine if the
thinset will properly adhere to the slab.
My slab has a shiny finish to it. Almost like it has been polished.
Any ideas? I guess I'm back to putting new carpet down instead...

Moisture in the form of vapor will permiate through the cement floor. If
you trap it with a plastic barrier there is no question that water will
eventually form between the cement and the plastic barrier. It's not a
matter of not having a problem to date as it is when will it finally show
up. No problem with tile as the vapor manages to pass through.
Direct some of your A/C down there. Small opening in at
the far end, an intake at other end. Or a louver in your
basement door. That's the one I prefer, so that you don't
risk pulling gas fired appliances exhaust gases.
