Concrete Countertop Sealers

A wide range of materials can be used to seal concrete countertops. Each concrete countertop sealer has its own performance characteristics and maintenance requirements. Methods of application may be an important consideration. In the kitchen, a prime issue is whether a sealer is food-safe.

Penetrating sealers - soak into the concrete countertop surface and dry to a nearly invisible appearance

Film-building sealers - Wax is the most basic film-building sealer. There are a variety of waxes that can be used, including plain beeswax; however, automotive waxes should be avoided because of additives in those formulas.

Epoxy for Concrete Countertops - Often two-component systems offer a durable, hard surface that is very resistant to staining, but they can be affected by UV light if a UV inhibitor is not part of the formula. Epoxies create a very shiny surface and are subject to scratching. Sensitive to heat.
