Ceramic Tiles on Wooden Floor

I am about to tile a kitchen floor. AS the floor was chipboard, I have covered it in 12mm ply and screwed it down every 6inches in every direction.

The plywood I used was exterior grade which I believe means waterproof and I have been told to use flexible tile adhesive. Someone mentioned that it is probably still worth painting the floor with a PVA/Water mix first.

Is this correct or is it not necessary ?

Thanks

Our builder recently did exactly that - the dusty, dry ply surface didn't look promising

I would - dilute PVA takes moments to splosh on and dries quickly...

It seals the surface and stops the ply sucking the moisture out of the tile goop and weakening the join.
