Depends on temp, but 24 hrs is good if it's warm (70's). If it's cold, longer.
It will physically gel VERY quickly and must be applied and assembled before that happens. Like within 5 min.
Clamping force is VERY beneficial, but LEDs don't tolerate much force on the lens and simply holding it is unacceptable. You can't hold it without letting it move at all for a half hour or hour or whatever.
You say "swapping emitters on a Star".
Do you mean removing an emitter? Stars don't cost enough to want to scrap the emitter to save the Star board. And, I *DID* do this once, the device probably cannot be removed anyways. It'll break in half but you still won't get the base unglued.

Use as little adhesive as possible. You want to get full coverage, but the thickness of the layer needs to be thin, thin, thin!! AA is not a very good conductor of heat compared to the aluminum heatsink, so you want to get the emitter as physically close to the heatsink as possible.
If the star is held to the light with screws, use as many screws as possible, and tighten them as much as possible. Use a lot of clamping pressure when setting the LED. If you have a drill press, you can open the chuck so it presses around the lens of the emitter. You can also apply a lot of clamping pressure, to "squish out" excess adhesive.
