advice on entryway tile subfloor
I am renovating my living room and wanted to expand my small tile entryway into the living room.
Currently there are 4x4 tiles that will be removed. They are on a .5" plywood subfloor with .5" plywood as an underlayment. The tile and underlayment will be removed and I will put plywood back down so the entryway floor and the living room floors are level.
The living room subfloor consists of .5" plywood with .5" chip board on top. (Its not OSB. It looks like MDF but with larger fibers.)
What I'm wondering is can I put my cement board down on top of this? Or can I sandwitch it with a piece of .375" plywood then the concrete board?
I am installing 12x12 ceramic tile. About 40 sq ft.
