Where I've removed the tiles in our bathroom its taken the top layer of paper off the plasterboard.
This has left the top surface as brown flakey paper.
(Its not in a wet area of the bathroom, the wall is half-tiled for decoration)
Focus DIY helpline said sand it a bit to get the flakey bits off and then just tile straight onto it again.
Is this reasonable advice, or should I be looking to get some sort of plasterboard sealer/primer?
