The procedures you need to follow are dictated by the adhesive manufacturer. BAL state to seal back and sides with BAL Bond SBR and NOT to prime the tiling face. Ardex however, say to seal back and sides with Polyurethane Varnish and prime the tiling face with P51 primer.

Check with your chosen adhesive manufacturer before you continue.

Good question.

Seal the back and edges but refer to the adhesive manufacturers as many of the don't recommend to seal the face and you would have to use a raid set :Pete

Ply is not the ideal substrate for tiling on bathroom walls it is affected too much by humidity. Much better to use plasterboard and tanking membrane, or cement based backer board. Bonding plaster is also not suitable to tile straight onto.
