How long to let GE silicone cure?

[WhiskeyCoffee]

I picked up some GE 100% silicone Type I and was wondering how long I should let it cure in my sump before using the sump? The bottle says 24 hour cure time but I've heard I should wait much longer. Thoughts?

IMO, if you can smell it, it isn't cured yet. 24 hrs is for a standard bead size. If you use a larger bead (like I did on my sump) it could take much longer. Mine took 3 to 4 days before I couldn't smell it and I waited another 3 days to be on the safe size.
Since curing requires off gassing, doubling the thickness of the bead more than doubles the cure time.

Return it and buy momentive rtv 100 series. momentive is commercial grade, GE is junk. cure time can be a full week depending on bead size.

No, graingers or Amazon. I used it when I used to build glass tanks.
