I recaulked around my tub last night with 100% silicone caulk. It's now been a bit over 12 hours, so the caulk is set and I can get the tub wet (according to the instructions on the tube), but the bathroom still stinks of silicone.

The bathroom is pretty small, only about 6x10'. I don't know the CFM of the vent fan, but it has been running constantly for about 12 hours (from just after I finished the caulk job), and there's a pretty good gap under the door to allow fresh air to flow in.

How long should I expect that smell to remain?

A few days. Solvent will continue to escape the caulk from deeper in for a short while. After a week you probably won't detect it, but that depends on the nose.

  • Yes. It was a week before my wife stopped smelling ours. I stopped the next day. – Michael Harvey Jun 15 at 17:09
  • My wife kept turning the bathroom fan off because she couldn't smell it, but I could. For me, the smell went away shortly after I posted the question. – FreeMan Jun 17 at 12:06
