I can't seem to get the Marble Plaster to polish. What am I doing wrong?Updated a year ago

The technique of burnishing the Marble finish is dependent on drying time.  Burnishing too early may result in a finish that does not achieve the desired polish.  Burnishing too late can cause excessive mottling and has the potential to leave burn marks on the finish.   It is essential to have awareness of environmental factors that may influence drying time.
