Generally in slab conctruction they lay tille on a membrane anyway. It
should be fine if your peel and stick is well stuck. If you are
nervous about it use flex mortar.

I should have specified that the sub-floor beneath the peel and stick
tile is plywood, not concrete. Does this make a difference?

A friend of mine, at the time, laid peel-and-stick on a hardwood floor
that was maybe 100 years old in a building that had been a printing
compnay iirc. It only lasted a couple weeks before it came unstuck.

I'm sure your plywood was a lot cleaner.

Thanks,
