To create a honed surface means to leave it smooth and flat with a matte finish. This is achieved in a number of different ways. A stone which is being diamond grinded and having lippage removed will eventually show a honed finish as the medium resin grades of diamond are used. At this stage a honing powder will be used to enhance the smoothness of the surface.
These honing powders are made from a blend of abrasives compounds and can also be used to remove ring marks on a table or counter left behind by a glass or mug. Some manufacturers produce a whole range of powder grades which will remove minor scratches and also etching as well as producing a fine smooth finish.
Some limestone will not polish and so grinding it with very fine diamonds will produce an ultra-honed surface and so powders may not be required.
