Yes. All stone countertops, including marble and granite, should be sealed to protect them from staining. Stone countertops are a beautiful and durable addition to any kitchen. But like all natural materials, stone is porous and can absorb spills and stains. That’s why it’s essential to seal stone surfaces to help protect them from damage.A quality sealer will penetrate deep below the surface, creating an invisible barrier that resists stains, spills, and everyday wear and tear. As a result, your stone countertops will stay looking beautiful for years to come. We will seal your new marble or granite countertop at Atlanta Stone Creations twice before installation.Over time and through regular usage, the sealer on your countertop will naturally wear out. That’s why we recommend sealing once a year or upgrading to a sealer with a 10-15 year lifespan. By sealing your stone surfaces, you are ensuring that your countertops will look as beautiful as the day they were installed for years to come.
