I have a kitchen that has breezeblock walls. On this there is dot and
dabbed plasterboard. This plasterboard has been skimmed.

The previous owners have managed to remove the old tiles sucessfully and
then retiled using mosaic tiles. These mosaic tiles appear to be 15mm by
15mm.

8 by 8 of these tiles appear to have a hessian back to them (obviously
designed to make tiling easier in the first place)

I have a requirement to remove these mosiac tiles. However, no matter
how careful I am, I cannot get the tiles and tile adhesive to seperate
cleanly without damaging the plasterboard.

I find that the skim plaster is coming off with the tiles taking the
paper off the PB too. In extreme cases, the plasterboard is coming away
with the tiles leaving me with holes in the plasterboard.

I can see myself having to remove the PB completely from floor to
ceiling and fitting new sheets.....

Anyone suggest a method that actually works?
