I have a lath and plaster ceiling that is badly crazed and has previous water damage. I want to put new plasterboard over it and new fibrous cement cornices.

What is the best method to do this. Is it best to fix battens to the underside of the old lath and plaster ceiling and then fix the plasterboard to them. Or do you just screw the plasterboard direct to the existing ceiling joists with longer screws? I was thinking with the flaking finish on the old ceiling that I would not be able to get adhesion with plasterboard adhesive if I did not use battens.
