The bonded mud bed cares more about the cure of the concrete below than would a reinforced, unbonded, mud bed (which wouldn't care at all) but I would still wait a week for the concrete to cure before placing the bonded mud bed. See my warranty information below.

The mud bed, as I said above, needs cure only a minimum of 20 hours, but it's still a bit delicate to work over at that point. Your toes will make lots of divots and you'll likely need knee boards. Been years since I've done a large mud floor and I don't recall how long it takes before they're solid enough for careful foot traffic. Maybe one of the guys doing them regularly (like Davy above) will weigh in on that.

My opinion; worth price charged.
