Before the surface has dried out completely, it is possible to create grooves (like in a grammophone record) in the surface by polishing with a stone. This is using the stone in the "wet" fase of Tierrafino Stone. By doing this you can determine any wanted movements in the surface which you will be able to see eventually by different angles of light that they will reflect. By waiting shorter or longer with polishing with a plastic trowel, the grooves made by the stone will be erased more or less. It is possible to finish the wall/object solely with a stone.
