No, engineered quartz countertops do not need to be stripped and resealed every 18 months. Unlike natural stone countertops, such as granite or marble, engineered quartz countertops are non-porous and do not require sealing.
Engineered quartz countertops are made from a blend of 90-95% crushed quartz crystals and resins, which are then formed into slabs. The manufacturing process makes the surface extremely durable and resistant to stains, scratches, and bacteria. The non-porous nature of engineered quartz means that it does not absorb liquids or moisture, reducing the risk of staining.
To maintain and clean engineered quartz countertops, you generally only need mild soap and water or a non-abrasive household cleaner. Avoid using harsh chemicals, abrasive pads, or scouring powders, as they can damage the surface. Routine cleaning and wiping up spills promptly should be sufficient to keep your engineered quartz countertops looking beautiful and pristine.
It's essential to follow the manufacturer's guidelines for maintenance and care, as different brands or specific finishes may have slightly different recommendations. In general, though, the main advantage of engineered quartz countertops is their low maintenance and the absence of the regular sealing required for natural stone surfaces.
