Sealer and Finishing Wax

All concrete countertops need to be sealed to protect the concrete from food stains and scratches. The right sealer will not only protect the surface, but also enhance the color and sheen. For additional protection and luster, some countertop installers will also apply a finishing wax. This sacrificial protectant will help to preserve the sealer but requires regular re-application to maintain its effectiveness.

Buying tips: "There are a multitude of concrete sealers on the market, but it's important to choose a product that meets the unique performance requirements for countertops as opposed to floors or exterior flatwork," notes Girard. He recommends using a heavy-duty sealer that is food-safe, colorless, non-yellowing, and heat and scratch resistant.

You can find finishing waxes specially formulated for use on concrete countertops. Most are made from beeswax or carnauba wax and can be applied with a soft cloth.
