Postcrete

[bednobs]

how long does it take to go off?

[Zacs-Master]

Couple of hours in this weather.

Zacs is right for "first set", but leave it alone for 24 hours or it'll come loose.

Without wishing to upset earlier responders, I would strongly recommend leaving any concrete/render totally free of additional loads, knocks, etc. or any interference for no less than three days. During that time ensure it does not dry out by either wetting it regularly (after first set, or 3-4 hours, not before) or closely overlaying it with plastic sheet.
