Are there no fixing instructions with the panels . I work with a guy who sometimes puts pva panels and he battens the ceiling and uses hidden nail technique . Have you tanked the ceiling ? If not it doesn't gave any relevance to the question if you have and you intend sticking panels then as above .Hi I have tanked my shower with mapei waterproofing,now I need to stick pvc panels to the ceiling.can anyone recommend something I can use please.
