In my experience tiles directly onto plasterboard don't stay stuck for
more
than a year or so. The slight flexing of the plasterboard unbonds them.
I
have used Wickes cement based board intended for tiling in wet places
and
so
far (4 years) it has stood the test of time.

Bit late for that! That part of the project is well and truely in place.
Removing it would be a real problem...

I know that the plasterboard has to be well treated for the tiles to
stick.

Cheers, Rob.



Round showers and baths is the real problem - the grout line develops tiny
cracks - the water gets in, and off pops the tile !
