Will they get worse or do I need to replace the sink?

    Hello Joanne

    If it were me and I had the funds I’d replace the sink. A crack in it is just a disaster waiting to happen and you really don’t know when it will either.

    There is some sealant you can cover it with but I don’t know anything about it at all.

    ( looks, price, ease of use, messy? )

    For me by the time I would through all that trouble I’d just find another sink.

    Good luck ☘️

    I agree, I'd start looking for a new sink. But you can probably use this for a short time while you look--just don't leave water sitting in it, it might leak.

    Yep. It will get worse. For a temp fix...clean the crack with white toothpaste and a toothbrush. Rinse and dry well. Force two part into the crack. Wipe excess off with nail polish remover.

    You might give Loctite Paste a try to attempt to repair the sink. It can be sanded after it dries and has worked on porcelain sinks.

    Amazon has repair kits to fix cracks but I would replace the sink if possible. If is cracked that is a weak spot.
