I re-caulked my bathroom a few months previous and there are a couple of gaps that have appeared. I have been caulking my own bathroom for about 7 years now but have never had damage this soon into it. My kids just started having showers and are now standing more than sitting so I am guessing that is a contributing factor.
So there are two spots of about an inch in length that need to be fixed. My understanding has always been that the whole length of the caulk would need to be reapplied. I heave a sigh at that notion since I really don't want to do it again right now.
Your caulk needs to attach to both the tub and tile
Knowing that I could remove the damaged areas and caulk again with larger applications over existing good caulk to get contact to the tub and the surround.
There is also a very similar question about How to fix small holes/separation in caulk around bathtub? but the answers focus more on the tub installation itself rather than the caulking. While, at least one, recommends redoing the whole thing in that case I wonder if it is related more to the installation rather than the actual title of the question.
Can I re-patch small sections of damaged caulk or is it just smarter to redo the entire thing? I think from reading I might be able to get away with small patches but I have a nagging feeling that I would just be postponing a whole re-caulk.
