How long must concrete dry before it rains on it?
First of all, concrete does not "dry" to become hard. It cures, which is a chemical interaction between its water and its portland cement. Usually, a couple of hours is plenty of time for concrete to 'set' enough to not be damaged by rain. The best and strongest concrete never dries out for the first 28 days from pouring it.

Can you pour concrete on a concrete floor with an epoxy coating?
You must remove the old epoxy coating before pouring the new floor, for otherwise there will be no bonding. If the epoxy coating is thin (e.g, paint) then it may be possible to remove it by hand sanding. If it is a thick coating, then sandblasting is probably the best method. In either case, appropriate dustmasks and other safety precautions are essential. Good luck
