Preparation to walls after taking old tiles off,and to re-tile after !

[tony4173]

Hi guys,

Not sure if this is a tiling question or a plastering question,maybe both.

Just been today to look at a job for a friend to tile 15m2 in his bathroom. He has removed the old tiles but the adhesive is stuck that well to the wall it would take about a month to take it all off nibbling away at it in readiness for re-tiling, My question is....what is the best way to tackle the bad walls as obviously it has to be flat for a better and easier tiling job. On one wall there is a concrete lip running across the wall above the bath.
Do I ....

(A) apply a thin set bonding coat ,and would this be strong enough to take the tiles after ?
(B) thickish skim coat ?
(C) sand/cement render coat ? or any other options excluding dot n dab (expensive).

Thanks for your time

Dot/dab plasterboard is not expensive.

Ad above....plaster board. Can tile the next day..
Don't cover with bonding it's not suitable for tiling.

15m2 of boarding would cost about £30 plus a couple of hours labour, but it will make the tiling sssooooo much easier , board it tony
