Repairing wall ahead of tiling advise

[Bobthebuilder95]

Morning

Have read lots of posts but can't find one that's exactly my situation. Essentially in my en-suite where we are replacing the shower cubicle 2 of the 3 walls are blockwork rendered then skimmed and one wal is plasterboard.

When getting the tiles off the backing thistle plaster has come off in a few localised areas where it has blown. And the plasterboard was also damaged.

I was thinking patch with thistle bond cost then skim with multi finish on those two walls then on the plasterboard wall take the board off and replace with a backer board. What's your thoughts? Seen some people suggest taking it back to blockwork then backer board but that seems excessive and more expensive!

Thanks,

Rob

Rob, why not post pics.
search the plastering and tiling forums for loads of info on exactly what you ask.

Your idea sound fine though no need to put a finish skim on if you are tileing.
