We noticed our bathroom counter is starting to crack and wanted to know if there is some sort of good glue for this. I think in the future it’ll need to be replaced but want to make sure it does not just fall right now.

  • looks like a piece of natural stone used as a topper on a pony wall as the base for a 1/2 glass wall. someone probably put too much weight on it and it has an overhang. need more pictures from other angles to give suggestions. Feb 8 at 2:11
  • Thank you! i added some more pictures, i thought this was a tile i am not 100% sure what it is.

The trick with glues is that you want something with the same properties as the substrate material. For stone tile, you need something with stone-like properties, e.g. grout. You only need a tiny bit and it's sold pre-mixed. In my experience, siliconized acrylic grout works best for this sort of patch-up work.

  • Should i try to use a toothpick to push it downwards into the crack? also the grout will be white? Edit: never mind i see they have different colors

    Grout has a relatively low tensile strength, so it's not going to repair this at all. It'll look nice, but it won't prevent further separation.

    If you really want something solid -- tinted epoxy is (entirely too much of) a Thing...

    Neither the regular grout, epoxy grout or siliconized grout are going to fix the problem in terms of adding structural strenght. It is just a cosmetic fix while the stone is replaced.
