"Silicone sealant is a versatile and flexible waterproof sealant with a multitude of applications (see the Putty & Mastic article for other types of sealer).
It is particularly good in situations where you need to make a waterproof gap seal, but cannot completely eliminate movement between the parts to be sealed. Its key features are:
Remains permanently elastic after curing. Long life expectancy in many applications. Does not shrink. Water based formula. .... Supports mould growth"
