Tile directly on 6mm ply?

[Scatz73]

Hi,

Advise needed please... We are renovating our house and the builders have secured our floor boards and then glued and screwed 6mm ply board on top.

Can we use flexible adhesive directly on that or would we need to add another layer first?

Many thanks,
Matt

Prime the ply and stick 6mm backer board on top and screw that down, plywood is not suitable to be tiled over.

I would even rip the 6mm ply up and use backer board ,but wrong imo to say ply not suitable ,if you use the right thickness no problem with ply

if you have a marine plywood its suitable.
