I've just removed some kitchen wall tiles with the SDS. I'm not familiar with the construction of plasterboard. The adhesive on the back of the tiles appeaers to have taken off the top layer of board, leaving a brown surface a little like torn card (not gone through to the plaster).
I'm hoping that this convoluted description will enable someone to tell me if this can be painted straight onto, or if not, what treatment it needs first. Surely it doesn't need skimming?
