PVC Cladding over plasterboard with textured paint finish

[Michaelsf90]

We are doing all of our bathroom in the next few weeks. We already have the cladding but I was wondering should I clad straight over the plasterboard or rip it down as it has a textured paint finish. The house is 1930s and the original ceiling is lathe and plaster. The bathroom ceiling has been battened and overboarded with plasterboard. I can either clad straight to the plasterboard or rip it down and clad. I just don't know if I could clad directly to it with textured paint

Wedi washer and tile backer board screwed over than clad over that maybe

If you can pull down and get rid of it all that maybe better but the mess

Pvc ceiling cladding. I don't mind the mess as the bathroom is being stripped right out. New tiling. New flooring. New ceiling. It's battened at 600 centres at minute with it being plasterboard. Cladding ideally needs to be every 400
