No, quartz countertops do not require sealing. Unlike natural stone countertops such as granite or marble, quartz countertops are engineered stone surfaces that are made by combining approximately 90% ground quartz with resins, polymers, and pigments. This manufacturing process creates a non-porous surface that is highly resistant to staining and does not require sealing.
Quartz countertops have excellent durability and resistance to liquids, including common household spills. The non-porous nature of quartz means that liquids and stains will not penetrate the surface, making it easy to clean and maintain. Regular cleaning with mild soap and water or a non-abrasive household cleaner is typically sufficient to keep quartz countertops looking their best.
It's important to note that while quartz countertops are highly resistant to staining, they are not completely impervious. Certain substances such as strong chemicals, solvents, and abrasive cleaners can potentially damage the surface. It's always best to follow the manufacturer's guidelines for cleaning and maintenance to ensure the longevity of your quartz countertop.
