I asked a pro who has been tiling for 25+ years and he says no way
can he grout wall the same day, needs at least 24 hours in his
opinion with ready mixed (even pro stuff) wall tile adhesive.
Possibly longer if the wall is impervious.

Maybe I ought to stop doing this then and think about a career
change, been tiling now for 15+ years and NEVER been called back to a
tile falling off. Even been back to the same houses to remove my
tiling when new owners moved in and they were stuck fast!

My original answer to the question is repeted below.

You can get 'quick drying' tile adhesive (3 to 4 hours till set).
This is usually used by 'professionals', it is more expensive than
normal stuff, but allows them to tile and grout in the same day,
therefore moving onto the next job tomorrow and make more money.

Whats this quick set tile adhesive called?
I've asked at 4 tiling outlets, all used by pros, in the town where I live
and none of them have a ready mixed quick dry for wall tiles.
They only have quick set powder mix for floor tiles.
