Base for tile
i ripped up some pergo-like flooring to put in tile but I'm not sure what exactly I have underneath and am trying to figure out my best bet for what to pull up and what I need to put down.
Here are the four layers I think are there from top to bottom:
====PERGO LAMINATE (PULLED UP)=====CABINETS/APPLIANCES==
=====PLYWOOD, FLUSH WITH ORIG. PARQUET IN NEXT ROOM====
============POSSIBLE OLD TILING=======================
Thanks for the advice.
