A common mistake that many people make is thinking that a sealer recommended for use in sealing concrete floors will work for countertops. This is not the case. The performance requirements for concrete countertops and concrete floors are vastly different. While a floor sealer is optimized for foot traffic, it is not necessarily optimized for use in a kitchen.

Bare concrete is porous in nature. As a result, it is vulnerable to chemical attack and staining. If you spill something onto a concrete countertop, the liquid will likely soak into the surface of the concrete and can actually stain the concrete. Acidic substances, such as lemon juice and vinegar, are even worse. They can actually dissolve your concrete and create etching. In order for a concrete countertop to perform as expected and be durable, it must be sealed with the right sealer.

The best concrete countertop sealer will enhance the look of your concrete without changing the feel of it. Additionally, it should be nonporous and resistant to staining from food and oil. Look for a concrete countertop sealer that is resistant to etching, heat, and UV degradation. Finally, it should be food safe and completely nontoxic.
