Read it: Can you reseal a bath or shower without removing the old silicone?
It grows inside the silicone, feeding on soap residue in a joint that never fully dries. What actually slows it down, and what makes no difference.
Read it: Why does bathroom sealant go mouldy, and can it be stopped?
Touch dry in under an hour, usable after twenty four. Why those are two different numbers, and what happens if you do not wait.
Read it: How long does silicone take to dry, and when can you use the bath?

Read it: Why does bathroom sealant leak, and is the sealant even the problem?
