I will be puting a shower base down in the morning onto an exterior ply
'sledge'. What strength should the sand & Cement be (4:1, 5:1...) and
should it be reasonably dry or sloppy so the base settles into it?

Cheers

I am the original poster of this. I have now done the tray. As I need to
now install the cubicle etc. How long do I need to leave the mortar before
it is set enough for me to stand in the tray. If it helps with calculations
the tray is 800mm square and the mortar is approx 1/2" (13mm) thick.

Cheers

John
