The Bunnings Workshop community can help with your home improvement projects.
Hello @neelima
Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your bathroom basin benchtop.
If you are after a professional repair, I suggest engaging the services of a professional stone top repair person. They will be able to match the colour of your benchtop when they glue it together. They will also be able to disguise the damage and fill in any parts that may have chipped away.
But if you are planning to replace the top, but just want to fix it for the meantime, I suggest using Selleys 415g Liquid Nails Landscape Stone Concrete Adhesive. Itis designed for stone and masonry plus; it is grey in colour so will not stand out so much. My best advice is to wipe away any excess adhesive once you have pushed the broken piece in place. Make sure to give it enough time to cure before using the benchtop surface.
Please make sure to wear personal protection such as rubber gloves, goggles and a mask when working on the damage.
If you need further assistance, please let us know.
