Welcome to Touchstone Architectural Cement the home of Valtstone Systems. Valtstone is a light-weight cement overlay system and a process of creating color and texture in an “Old World” style that is both warm and beautiful yet functional, durable, and easy to care for. Thru a process developed over many years the Artisan creates each piece of work by hand and each piece is uniquely one of a kind. Colors are custom mixed to match your Décor and the settings in your home so each compliment one another. Since all Touchstone products are done on-site there are no seams or grout to contend with or catch dirt, debris and stains. Touchstone products age over time and develop handsome patinas and depth. Eric Valtenbergs has been “playing in the mud” for 15 years.

He lives with his wife Karen, five big cats and one very small dog! Eric’s Son Lucas continues to work in and learn the business of creating Art out of Cement.
