My parents have asked me to lay some porcelein tile in the kitchen. There is currently some vinyl tile on the floor (the sheet type, not individual squares) and I assume it has been glued down. Is it okay to put the tile on the old flooring? If so, do I need a special type of mortar mix, or will the standard type work. I was wondering about the mortar bonding properly with the current flooring.
I would appreciate any help and input. Many thanks! Ryan
