I'm planning to tile a kitchen and dining room area, it's about 600
sq'. There is currently a 1/4" plywood underlayment over particle
board. What type of mortar and grout is best to lay over plywood?
I am not willing to replace the plywood with a cement board.
I've done multiple bathroom tile jobs, but this area is much larger,
I'm more concerned about the base.
Thanks, lls8000
