Silicone caulk won't setup - what went wrong?
This shower is the about to do me in. If you read my earlier post about the shower leaking, my visiting BIL found a crack along the curb where the marble threshold meets the tile. He fixes that, everywhere else looks great, no problems.
So he reinstalls the shower door, silicone caulks the sides/bottoms etc. Looks great, says you can use it in a day or two when the caulk is set.
It's been 24 hours and the caulk feels like vaseline. Before he left and the caulk had been on an hour or two, it felt so greasy, so I asked him what he used, and why it was taking so long to set. He pulled out the caulk tube - mildew resistant, 100% silicone caulk for bath and kitchen use. Nothing out of the ordinary. He said maybe because it was really warm and humid out it's taking longer to cure etc. My house is air conditioned! It's not that humid inside that caulk would still feel sticky like freshly applied caulk almost 24 hours later???
