Yes. And as well to spice it up, you can do patterns and/or a variety of colors. Home improvement stores offer a variety of products, cost points, and finishes.

Thank you very much for such a thorough answer/response!

Cement stain. (Home Depot or Lowes both carry it)

Sounds like white portland cement, get the regular and paint it..... here's an old school mason showing how.... make sure its wet and not the hottest part of the day.... https://www.youtube.com/watch?v=iH_66_Qv1ew
