The frequency with which granite countertops and surfaces require sealant application is a variable dependent on several factors. These factors include the granite’s porosity, the type of sealant used, and the level of use and exposure to staining agents. A simple test to determine if resealing is necessary involves placing water droplets on the surface and observing if the water beads or is absorbed within a few minutes. If the water darkens the stone, it indicates that the sealant has worn off, and the granite is absorbing moisture, necessitating resealing.
Regular sealing of granite is important to protect the stone from stains, spills, and etching from acidic substances. Properly sealed granite resists the absorption of liquids, which prevents discoloration and bacterial growth. Historically, sealing natural stone surfaces was a labor-intensive process involving natural waxes and oils. Modern sealants offer more durable and longer-lasting protection, reducing the required maintenance frequency while maintaining the aesthetic appeal and longevity of the granite.
