Floor Tiling over 22mil TG4 Peel Clean Caberdec Chip Board

[beemerdude99]

I need to tile 2nd floor bathrooms in new builds. The existing floor is vinyl over the subfloor of 22 mil TG4 Caberdec Chip Board. Can I rip up the vinyl and tile directly over the chip board, or should I lay down hardibacker or other material first. If yes, what thickness would you recommend.

I think the gaberdek chipboard is the only one that they recommend tiling directly onto BUT I would always over board all day long, 6mm backer board would be fine. Cheers

I agree. Thanks. I appreciate it.
