shower sealant replacement

[neil leslie]

Is it possible to repalce a section of sealant or does the whole lot need to be redone in one go?

There is no tidy way of replacing just one section, because new silicone doesn't bond to old silicone all that well.

You need to completely remove all the sealant that's there, get everything really clean, then reapply.

Use a sharp knife to strip away most of it, then some silicone eater to remove the remnants.
