Which Adhesive

Thanks for that Grumpy.
Will the tiles lift if the back face aint treated.What alternatives do I have?

To be honest, you will almost certainly be ok. The sealing is to prevent moisture ingress and hence movement. If it was me, I would just carry on and hope for the best. Unless you have a problem in the house with damp or you have kids that make the floor a paddling pool, I am sure it will be fine!

the tiles might not lift but best practice is to seal the back of the ply wood if you dont wont to do this throw some backer borad on top of it or some ditra matting

i dont guarantee anything on ply wood and put that on my quotes there are so many good alternatives these days .years ago i used to staple wire mesh to the ply wood and then it was ardex x7 with ardion 90 in it ,didnt ever get any failures like that but have had probs with single part flexi a couple of times and 2 part also some people love ply wood just a case of once bitten twice shy for me
