How long after screed to lay shower tray.

[angliojoe]

Hi,
I have just poured some Mapei Ultraplan 3240 self leveller down to level the floor prior to fitting a shower tray. It says that it is walkable after 4-5 hours, does that mean I can install the shower tray after 4-5 hours or do I have to wait for the leveller fully cure first?
Thank you!

Walkable is set but not dry.
Means you can carry on but don't go digging or scratching. It's not fully hardened but you can stand on it or walk on at exit or entrance as an example.

how thick did you put it done. Usually the following day is best
