The process of sealing marble involves applying a special sealant to your marble surfaces to protect it. This sealant is absorbed into the tiny pores of the marble and creates an invisible barrier. It stops liquids from being absorbed by the marble and prevents unsightly stains. Coffee, tea or red wine spills don’t stand a chance!
