Montauk Black 12 in. x 24 in. Natural Cleft Slate Floor and Wall Tile brings the authentic color, texture and variation of genuine quarried stone to residential floors and walls. Each piece has natural cleft texture with shifting black, charcoal and gray tones, so no two installations look exactly alike. Where can black slate tile be used? Use this large-format natural stone tile in entryways, mudrooms, kitchens and bathrooms, or on shower walls, fireplace surrounds, feature walls and accent walls. The 12 in. x 24 in. format creates fewer grout joints than smaller tile for a cleaner, more continuous stone surface. What should you know before installing natural slate? Because it is real stone, color, thickness and surface texture vary from tile to tile. Blend material from multiple boxes before installation to distribute that variation. Sealing before and after grouting helps protect slate from moisture and stains, with periodic resealing recommended as part of routine care. Montauk Black works with rustic, industrial, organic modern and contemporary interiors. Pair it with warm wood, white or green cabinetry and brass or matte black accents. Each case covers 10 sq. ft. Measure the project and order about 10% extra for cuts, waste and future repairs.
