Epoxy and polyurethane sealers can last five to 10 years, while acrylic sealers last two to three years or more depending on the use, wear of the surface, and type of sealer you choose. Areas that see heavy traffic or extreme ice and snow may require more frequent sealing.

Concrete countertops can last a lifetime with proper maintenance. That includes regular resealing, waxing, and repairing any chips or cracks. At a minimum, they should last 20 years before major issues occur or performance drastically declines. The longevity of concrete countertops is a major reason people add them to their kitchens. It also makes up for the high cost of installation and added maintenance.
