A fine-grained metamorphic rock formed from shale by regional metamorphism. It is harder, more lustrous than shale and when split, yields approximately plane surfaces.
Used for countertops, flooring, showers, and vertical surfaces. Suitable for interior or exterior use, both residentially and commercially. Available in various sizes, including slab.
Seal with Impregnator Pro to maintain a natural color. To deepen color, seal with Enhancer Pro. Use Revitalizer cleaner for regular maintenance.
