Selkirk Stone is a man-made stone product comprised of Portland Cement, lightweight aggregates, and oxide pigments. It is created to be lightweight so it can be applied to nearly any structurally sound building surface without the need for a special footing or wall ties.

Q. How is Selkirk Stone made?
Selkirk Stone is molded after carefully selected stones. Each individual stone is then hand colored and cast to create a realistic representation of the originals. Due to the handmade nature of the product, no two stones are colored alike. All colors in Selkirk Stone become integral during the casting process, and the colors used are oxide pigments meeting the criteria of ASTM C979.

Q. Will Selkirk Stone fade?
Selkirk Stone’s coloring process creates color that runs through the stone as well as accents the face of the stone. The colors used are only the highest quality, and are stable. This creates a stone that will show minimal color changes, similar to natural stone, after years of weathering. You can be assured that your project will retain its beauty for the long term, assuming proper installation.
