Different stones require different procedures in order to restore them to a factory finish, or to remedy an undesired pre-existing problem.
Restoration of polished natural stone involves the removal of scratches and/or damage from the surface of the stone by means of mechanical abrasion. This is also known as diamond grinding. Natural stone reflects light and does not need a topical coating or wax to achieve this desired finish.
After diamond polishing, the floor can sometimes be enhanced further with the use of polishing powders- which usually contain oxalic and aluminum acid, sealers, impregnators, and crystallization.
