Foam Shower Pans

I’m putting down a foam shower pan and then adding durock to the walls after. How long does the thinset for the foam shower pan need to cure before I can get on the shower pan to hang the cement board?

You can hang your cement board on the walls first, but use spacer blocks to keep the board high enough to slip the pan under. Account for 1/4" thinset under the pan just to be safe.
