Natural Tiles on Plasterboard Advice and information on tiling and fixing tiles to a variety of surfaces

[dunaldo]

Hi, I am planning on tiling part of my bathroom walls, i have removed some of the old tiles and it has taken off the top layer of the plasterboard. There is now a brown coloured surface instead of the grey one. Can i tile over this or do i have to do something to it, and will it take natural tiles. Thanks

Personally I'd replace the damaged board or skim it.

Could you clarify what you mean by "natural tiles" please?

Cheers
