  • Yes, on reflection it’s not that clear.
    The red paint is what I want to remove, but in doing so it’s evident that there’s a thin layer of cement over part of the stone. It could be covering up all manner of defects, but I’d like to try and remove it and see the condition of the original stone.
    South of the pink line is stone, north is cement.
    I could try an SDS but I’m weary of taking chunks out of the stone. Maybe I’ll try a bolster first.

  • Are you sure it's a layer of something different? Sandstone is sedimentary and can wear down in layers.
