Plaster may and should appear "wet" for 2-3 days, however it has already set on the first day!
One more "trick" (for the day of painting) press plaster lightly with your finger - if it "gives" (dents) you can paint if it appears hard - should stop.
If you paint after the plaster had set, the pigment will just fall off as soon as it dries - there is no binder in fresco - pigment must be incorporated within the "lime crystal" during its formation (during the setting).

Properly plastered and painted fresco should have a little sheen of its own.
