A soot-black alternative to the natural light gray limestone on which we based our design, the Karndean Black Sands’ honed surface and deep uniform coloring provides a neutral base for modern farmhouse or industrial-styled homes. Black Sands features gravel-colored InteGrout which gives the tiles definition without the need for sealing. Korlok Select interlocking stone tiles are equipped with K-Core technology and stain-free grouting for a quick floating installation over most existing hard floors.
