How long do you let sealant cure?

I was having problems with smokeback on startup and after reading through the forums, found I hadn't sealed the stove adapter properly. I hadn't put sealant on the inside of the stove adapter before I put it on the stove. So, I took it apart at lunch, and put the sealant in there, and put it back together. How long should I let it cure, before I fire? I used the red RTV sealant and it says that with 1 hour the sealant hardens on the outside. And within 24 hours, it is fully cured. Should I wait the 24 hours? Or should I be good to fire tonight?

I let the heat cure it.

Success! Adding RTV to the INSIDE of the stove adapter plus the flashlight trick to find a few small leaks means no more smoke smell in the house. Not the prettiest of jobs. But, sealed up tight. I'll pretty it up when I do my end of season maintenance.

just cover it up with flue tape.

No, get some hi-temp hunter orange paint and paint everything .
