tiling on new plaster?

[leso54]

hi all, about to re tile my bathroom and i have some areas of plaster which sound hollow and will need patching, as these will be tiled over as i am re tiling all the bathroom as opposed to just round the bath as now, can i patch with bonding plaster and tile on top of that or will i have to bond then skim as if it was a finished wall?
don't know whether this is the right forum but i'll post on the plastering one as well, many thanks for reading.

Just use one coat plaster.

thanks for the replies, another query is what is the best way to do external corners ie plastic finishing strip or mitre them on a machine and then grout?

 

[gcol]

Trim for me. Mitred tiles are easy to chip.

thanks for that gcol, never thought of that aspect, is there any recommended gap for certain size tiles?

 

[gcol]

Have a read of the sticky - I remember putting something about spacings in there.

I know when you come on a site for the first time you just want the answer and want it quickly. Invariably, sticky posts don't always cover what you'll be asking about, but in the case of tiling, there's not much to it so most basic topics are covered in that sticky. Glad you found it of use.
Be proud and post some pics of your handywork when you've finished - it's always nice to see a freshly finished bathroom.
