Indian Black Column Cap & Wall Cap 21x21

PRODUCT TITLE Indian Black 21" x 21" Natural Stone Column & Wall Cap PRODUCT DESCRIPTION Crown your masonry with the definitive weight of the Indian Black Cap. This premium natural stone slab is a masterful study in depth and density, featuring a massive square format in a curated palette of deep obsidian, charcoal, and midnight black. The Indian Black is designed to create a sophisticated, protective "lid" for your architectural elements. When used atop a stone pillar or a garden wall, the chiseled or eased edges interact with the sky to provide a crisp, architectural shadow line. Engineered from high-density natural stone, it acts as a functional shield against weather while ensuring your "monoliths" remain imposing and pristine for years to come. KEY FEATURES Absolute Midnight Palette: A deep, consistent black that provides a powerful contrast to lighter stone veneers or lush green landscapes. Functional Drip Edge: Designed to direct rainwater away from the face of the column, preventing staining and moisture damage to the stone below. Large-Format Scale: The 21" x 21" footprint is perfectly sized for standard 18" or 20" columns, providing a professional 1/2" to 1" overhang. Natural Thermal Resistance: Stays cool to the touch and resistant to the thermal shock of freeze-thaw cycles. Extreme Weather Performance: Dense, low-porosity stone that resists UV fading and acid rain, maintaining its "new-stone" look indefinitely. SPECIFICATIONS Material: Natural Stone (Granite / Basaltic Slate) Size: 21" x 21" Square Thickness: 2" (Nominal) Finish: Honed or Natural Cleft with Hand-Dressed Edges Weight: Approx. 85.00 Lbs per piece Application: Column Tops / Wall Coping / Gate Pillars Country of Origin: India Look: Monochromatic / Solid / Honed Stone INSTALLATION REQUIREMENTS ⚠️ CRITICAL: Due to the extreme weight of these 85-lb caps, you must use a High-Strength Stone Veneer Mortar. A standard thin-set is insufficient for a horizontal cap; a thick-bed mortar is required to ensure the cap is perfectly leveled and securely bonded to the column core. Manufacturer Recommendations: Recommended Mortar: A Type S masonry mortar or a specialized large-format stone adhesive (such as LATICRETE 254 Platinum) for maximum bond. Sealing Requirement: To maintain the deep "Black" luster and prevent water absorption, apply a color-enhancing penetrating sealer immediately after installation. FREQUENTLY ASKED QUESTIONS Will the black color fade in the sun? Unlike dyed concrete caps, this is natural stone. The color is "through-and-through" and will not peel or bleach, though a UV-rated sealer will keep the "wet" look vibrant. Can this be used for seating? Yes. At 2" thick, these are incredibly stable and make excellent tops for fire pit surrounds or garden sitting walls. How much overhang do I need? For a professional look, the cap should be 1" to 2" wider than the column itself. A 21" cap is the industry standard for a 20" finished column. PRO INSTALLATION TIPS Check Your Pitch: When installing on a wall or column, slightly pitch the cap (approx. 1/8") away from the center or toward a preferred drainage side to prevent standing water. The Two-Person Lift: Never attempt to set these caps alone. To avoid damaging the corners or the veneer below, two people should lower the cap onto the mortar bed simultaneously. Clean the Underside: Before setting the cap, wipe the bottom surface with a damp cloth to remove any stone dust. This ensures the mortar bonds directly to the stone rather than the dust.
