Stone sealing is a protective process applied to natural stone surfaces, such as granite, marble, or slate. It involves using a sealant that penetrates the stone to create a barrier against moisture, stains, and dirt. This helps maintain the stone's appearance and prolongs its lifespan, making it easier to clean and less prone to damage. The sealing process typically requires cleaning the stone surface thoroughly before applying the sealant. Depending on the type of stone and the sealant used, the protection can last from several months to a few years. Regular maintenance and reapplication are essential for optimal protection.
