Periodically, the stone will need to be restored. Perhaps a proper maintenance program was not followed, or the type of stone you have is not suited to the conditions it receives or for other reasons, the stone just isn’t responding to maintenance. How often this will need to be done is difficult to determine. Generally, if all the precautions above are followed, restoration may only be needed as often as once per year or as little as once every five years. The restoration process re-hones the stone to remove deep scratches and is then re-polished. Do not attempt the re-honing process yourself. A great degree of skill and experience is necessary for this task, so please call a reputable restoration company.
