Mountain Slate

Code: RKT3003-G
An authentic slate design, Mountain Slate’s mushroom gray coloring with brown-gray veining is an attractive tile suitable for a wide range of commercial settings. Equally stunning in office reception areas and restaurants, this classic slate design with non-staining, shell-colored InteGrout™ has a truly timeless feel.  

Warmer underfoot than natural slate flooring, Mountain Slate is equipped with K-Core® technology and 5G® locking mechanism for a quick floating installation over most existing hard floors.
