I hope someone has a suggestion here.

I have undermount double sink in the kitchen and both sides are going down due to which there is gap between benchtop and sink. The water leaks into underneath cabinet.

I noticed that it was only held with liquid nail before.

How can I secure it and make it leak proof?

    Is it mounted above or under the bench?

    I'm a bit confused by your description. Any pictures?

    Either way the sinks need to be remounted correctly and correct grade silicone used to waterproof.

      Sorry it's undermount sink. When you say correct grade silicon, how do I find it?

        Undermount sinks are supposed to have fasteners / clips depending on which brand and model to anchor the sink to the benchtop, so they don't sink down. Also depends on benchtop material.

        This sink needs to be remounted not just filled with silicone. If you do not understand how it needs to be mounted then you need a handy person or plumber to remount and silicone the inside edge.

        Silicone can be a b1tch to work with so again if you don't know what you are doing get someone else in. Amateur laid silicone looks terrible and probably won't be a good seal.

        Also, did you end up getting your jb hifi refund for the laptop?

        You may need to get a stone mason person to attach the clips as it looks like you have a stone benchtop and I would NOT advise you drilling into it to fix the clips.

    Have you bothered to open your cupboard door and poke your head under there with a torch and have a look at what is going on? You might just have some nuts or screws loose. Could be a 5 minute fix.

      Yes already did and only found liquid nail.

        Which is now dried, crumbly useless nail

        Sound like it was never mounted, just silicone on for looks ( like a fake facade ).

        Have a look at how one may do it - looks like PITA to do. Btw, there are meant to be clips that holds it securely. Have fun.

        Its more than likely epoxy, not liquid nails

    Use something like this https://www.amazon.com.au/Undermount-Sink-Clips-Supporting-B…

    A quick fix would be to just bog up the gap and stop the water leaks.

    For this I'd recommend Sikaflex pro. The correct type will support the weight of the sink.

    Sikaflex is a non silicone based product often used as a bonding agent for joining car body parts and even attaching spoilers and body kits.

    Sold by Bunnings and most hardware stores.
