Granite sealing is a process that involves applying a protective sealant to granite surfaces, such as countertops or floors. This sealant helps to prevent stains, moisture, and bacteria from penetrating the porous surface of the stone, thereby maintaining its appearance and durability over time. The sealing process typically requires cleaning the granite thoroughly before applying the sealant. Depending on the type of sealant used, it may need to be reapplied every one to five years to ensure continued protection. Regular sealing can help extend the life of granite surfaces and keep them looking new.
