I know it's been a while, but I'd love to see some images of the end result!

there is limited backsplash... one side of the gallery is a bank cupboards.. the side with counter top is open to family room or windows to outside deck and small return which is wall...I am thinking of keep that with white tiles ... also replacing sink with white glass double ...and new chrome fitting for taps and water filter...

My son used to help me cook in the kitchen - he is 190 cm, I am 175cm. I have an old-fashioned breakfast bar which is raised above the level of the kitchen benchtop. My son would stand at the raised section, I would stand at the lower section, it worked really well. An alternative might be to have a pull out step in the kick board spaces for your wife to stand on - I don't know if it would be high enough, but it might make things more comfortable. Speaking from the point of view of a tall woman, I will have my next kitchen cupboards and laundry raised at least 10 cm to make my life more comfortable - bending forward for any length of time is seriously UN comfortable!

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.
