I plan to install ceramic tile over a vinyl-tile floor. The vinyl is uncushioned and adhering firmly to the subfloor, which is a concrete slab.
I have read that to install ceramic over vinyl it is recommended to use a latex-modified or polymer-modified thinset (which apparently retains some level of flexibility even when dry).
What I haven't been able to find are recommendations as to just what brand of modified thinset to get and, equally importantly, where to get it. Is this the kind of thing Home Depot or Lowes carries?
Any experiences or recommendations out there? I would prefer a pre-mixed thinset, if possible.
