Cure/skin time for silicon rubber?

[scholar]

How long does it take for silicon rubber to skin for non-wieght bearing joint? and secondly to cure for weight bearing joints?

Aquick reply is appreciated as it is 10:15 Pm and I need to make some choices!

I'm not exactly sure, but normally I let silicon cure for at least 48 hours to be on the safe side.
