How long does shower sealant take to dry?

It might seem that certain shower sealants or caulks are dry to the touch quickly after application, but they actually take around 24 hours to properly cure fully.

The curing process can be sped up or slowed down in accordance with the level of humidity within the shower enclosure, and the home in general.

It is recommended to wait an absolute minimum of three hours, and up to 12 in some cases, before allowing water to come into contact with fresh shower sealant or caulk.
