Scratch and Heat Resistant, Can Be Cast to your Specifications

Made entirely of natural materials, this hardened mixture of water, cement, sand, stone and pigment isn't just for your basement floor anymore. It can make quite a statement up in the kitchen, and homeowners are taking note, as evidenced by its quick rise in popularity. The counters can be pre-cast to fit a mold or cast on site.
Concrete must be sealed properly to resist stains and water damage. However, many fans of concrete argue that there's beauty in the way the an unsealed surface ages, like the aged charm of a well-used butcher block.
Quick tip: For an added dose of personality, embed vintage tiles, shells or other object in the countertop. Finding concrete to be out of your price range? Investigate concrete tiles; Sonoma Cast Stone offers 25 ½" x 24" sections in 48 designer colors that work well for projects with limited time and budget.

Maintenance
Though your specific manufacturer's instructions reign supreme, concrete countertop manufacturer Sonoma Cast Stone recommends cleaning with a neutral pH soap, and being careful to avoid abrasive cleaners.
