Will silicone dry underwater?
While silicones are ideal for underwater applications, silicone elastomers/sealants/adhesives must normally be applied and allowed to cure in air (a process that takes from minutes to days) prior to use as sealants/adhesives underwater; otherwise, sufficient cure and good adhesion to substrates is not observed.
Can you apply silicone on top of silicone?
Never apply new silicone sealant over old sealant as, in most cases, the old sealant would have fallen away or split meaning that, no matter how much new sealant you apply, the leak will persist. Not to mention, applying a new sealant over old will look incredibly messy and unappealing.

How to use catalyst on silicone?
To use the catalyst, squeeze out a dab of it from the tube and apply it directly to the silicone adhesive. The catalyst hardens the silicone by removing water from the compound and increasing the purity of the adhesive. You can use 2 dabs of the catalyst to speed up the drying process even more.
How long does adhesive last?
If the tube is out of date, the adhesive will take longer to dry. If the adhesive takes longer to dry than it says on the tube, this is most likely because it has gone past its shelf life. Sealants, however, are good for about 12 months. Many adhesives say they come with a lifetime guarantee.
