Question clear silicone sealant won't cure

I recently replaced my kitchen faucet and used clear silicone sealant around the base to keep water from seeping underneath.

It was supposed to cure completely in 24 hours. That was almost two weeks ago!


This tube of sealant has been sitting in my basement for over five years. This has never happened with it in the past.


Has this happened to anyone else?


I'll have to replace the sealant. Should I just scrape it off with my fingernail and then wipe with rubbing alcohol? (I don't want to scratch the surfaces with razor blades and putty knives.)

Reg.

Silicone caulking isn't supposed to dry rock hard, it stays pliable and flexible so it can continue to work as intended. I suspect you applied too much caulk. Some solvent, a rag and maybe a plastic putty knife should help you to remove the excess. If you need to use a steel putty knife - wrap a rag around it so it won't scratch the sink/faucet.

Silicone should dry to the touch in less than 1 hr. If it still comes off on your finger, it is no good. Take everything apart, thoroughly clean, and start over. But silicone is not the thing to use on a faucet gasket. Use plumbers putty for things like that.

Why put anything under a faucet gasket? Rubber gaskets are self-sealing. Or is this a hard plastic gasket?

If the tube is really five years old, it could be too old, I'd buy a new tube and redo the job
