I ve learned and worked in Austria before come to England so brought things with me what worked in cases and I trust. As I fit the preps in my price i rather go for safety and take time on the job. Never had issues but fixes lots of crap work also you can use on tile over tile will not come off. It's personal preference how one like it's work flow and the entire procedure.
But if the existing tile are fixed badly and not knowing the methods that are used a fibre mesh won't hold them up....
