DEFINITION: Stone Sealing refers to the process of applying a protective product to a natural stone surface, like marble, granite or limestone to prevent damage and maintain their appearance. The sealant is typically a clear, liquid-based product that is absorbed by the stone’s pores, forming a barrier that helps to repel liquids, dirt, and other contaminants. Sealing stone can help to prevent staining and other types of damage caused by exposure to moisture, food and other substances. It can also make it easier to clean and maintain the stone surface over time. The frequency of sealing stone may depend on the type of stone, the location, and the amount of traffic or use it receives.
