New Shoots

Hi all,I’m looking to install some bathroom wall panels as part of a renovation I’m doing. I’ve removed the old tiles but the wall is in a really poor state. The panels are designed to be glued to the wall with a fancy adhesive but any tips on how to prepare this crumbling plaster so that the adhesive holds? Coat of PVA or a specific primer?
Battening out the wall is another potential option but in my past experience it didn’t give as good an end result as touching the shower panels between the studs sounded like a drum.
Thanks!
