And the cause of the problem.



adhesive dries out immediately if the plaster is left raw, it's like drying
mortar in the sun, it dries before the setting process has completed


Exactly,. Just what you want. Tiles grab fast and stick like ****.

Remember nearly ALL wall adhesives don't SET, they DRY. They are not
cement or plaster based, especially if ready mixed..how could they be?

So let em dry !

Simples!


best thing to do is get some
air movement in there, I left one ring of the gas cooker burning on
low (radiator was removed for decoration purposes and it was March)
and put an oscilating fan on the floor, might want to open a few
windows overnight too
Best thing is not shove stupid PVA on new plaster when you are going
to tile it.

What do you suggest instead?

Not using PVA.
