Arriscraft has introduced Thin Adair Limestone with more size and color diversity than its previous thin limestone product. The limestone is available in three sizes (face rises of 1 1/4, 2 1/4 and 3 1/2 inches) in various lengths and a random blend of natural sepia and blue-gray colors. A combination of veined, fleuri and cross-veined patterns augment the natural stone product. Thin Adair Limestone installs like tile, in a dry-mount style (without mortar), and can be oriented horizontally or vertically. The natural limestone is quarried in Ontario, Canada.
