thanks how2girl, but I guess my question is more about polishing concrete that has been sealed/oiled than it is about concrete benchtops (hence those threads were a bit generic). A bit more research suggests to me that a sander is the tool to use. I'm thinking of attaching some used carpet to a sander. I'm still unsure of whether to use a polishing cream - I think it perhaps can't do any harm though, and may add to the shine. Then the question becomes whether it makes sense to add bees wax over the top. To me, it seems it would protect the shine. But I'm guessing all of this.

For more feedback post some pics.

I’m in Perth, and have never seen a gap between cabinet and bench top like that, we don’t tend to use substrates here. I DO NOT think it is correct. Any load on the bench, may crack the bench top because it is not sitting flush on cabinets for support. I have attached a photo of the underside of my cabinets. I have checked all the cabinets and bench, they are all sitting flush, no gap.

Hi, Can suit Traditional, Transitional and Contemporary Styles of cabinetry and works equally well with either Grey or Beige palettes. Hope this helps, Malcolm.
