Hi All,
Bathroom project coming up. Part of it is to replace a wood parquet floor with ceramic tile. Parquet is 3/8" thick over 1/2 or 5/8" particle board over 2x8 T&G subflooring (nominally 1-5/8" thick). I'm concerned about achieving the same level on the new floor.
Can I remove the particle underlayment and screw concrete backer board (Durock aka Hardi-backer, etc.) directly to the T&G subfloor? My instinct says it is stiff enough without additional plywood underlayment. If I have to put a plywood base on top of the T&G I have no hope of getting the tile floor to the same level as the current floor.
TIA,
Casey
