That's if it's exposed to air. When it's sandwiched between glass and not exposed to air it takes MUCH longer. A week is a good guideline to follow to be sure it's fully cured.FSM;2875765; said:high-five for pointless posts
The GE silicone stuff says it cures in 24 hours on the tube I think, but it takes a lot longer when you have massive thick beads of it.
I resealed a 75 with that stuff, my eyes were burning like crazy when I got done.
I let it sit for about a week before filling, but that's only because I didn't have a stand.
