Noted regarding the galvanised washers & screws. The screws are zinc plated which i think is sufficient enough? (only exposure i forsee is the adhesive on top).
Still in two minds whether to sand/scrape/prime and adhere to boards to the plasterboard, as appreciate this was the suggested method. My only worry with this was that by bonding the boards to the plasterboard this would apply strain to the plasterboard, whereas keeping them more separate would rely more on the mechanical fixing which i have confidence in.
I may just say sod it and do both, as i am probably over thinking it.
