Product Overview MSI Royal White Splitface Ledger Corner “L” 6" x 12" x 6" is a specialized 2-piece, L-shaped natural stone corner panel designed to create flawless 90-degree outside corners for stacked stone installations. Part of MSI’s Rockmount® Collection, each corner panel is crafted from genuine splitface marble, featuring hand-cut stone strips arranged in a dimensional, splitface ledger format. The Royal White color profile offers an elegant, creamy off-white background subtly layered with warm beige, light gold, and pale gray undertones. Engineered as a 2-piece stepped "L" corner (6" height x 12" long leg x 6" short leg), it eliminates raw saw-cut edges and visible vertical seams at outside corners, matching seamlessly with standard 6" x 24" Royal White flat ledger panels.

Installation & Handling Guidelines ⚠️ IMPORTANT: NATURAL STONE LEDGER CORNER INSTALLATION PROTOCOL Install Corners First: Always set your outside corner L-panels first before laying flat ledger panels. Alternate (stagger) long and short legs on every row (row 1: long leg left; row 2: long leg right) to prevent vertical alignment seams up the corner. White LFT Thin-Set Mortar Required: Install using a high-performance, polymer-modified Large & Heavy Tile (LFT) pure white thin-set mortar (ANSI A118.4 / ANSI A118.15). White mortar prevents dark shadowing behind lighter marble pieces. Tight-Joint Installation (No Grout): Corner panels are engineered to butt tight against one another and adjacent flat panels without grout lines. Substrate Structural Rating: Ensure concrete, masonry, or cement backer board substrates are structurally rated to support heavy stone loads (approx. 8–10 lbs per sq. ft.). Pre-Sealing: Apply a high-quality penetrating natural stone sealer after installation to protect against dirt accumulation, water absorption, and environmental staining. Care & Maintenance Routine Cleaning: Dust or vacuum textured stone crevices using a soft brush attachment. Clean periodically with warm water and a neutral pH natural stone cleaner. Avoid Harsh Chemicals: Do not use acidic cleaners, vinegar, bleach, or high-pressure power washers at close range, which can damage natural marble surfaces. Periodic Resealing: Reapply a penetrating stone sealer every 2 to 4 years on exterior installations to preserve stain defense and freeze-thaw durability. Design Profile Aesthetic Inspiration: Warm Modern Minimalist, Tuscan Villa, Mediterranean Resort, Coastal Organic. Visual Advantage: Wraps corners smoothly without raw saw-cut stone edges, giving outside corners the substantial look of solid, hand-cut marble masonry blocks. Complementary Finishes: Royal White 6x24 flat ledger panels, warm natural wood millwork, champagne bronze or matte black hardware, and light travertine or limestone flooring. Frequently Asked Questions Why are corner L-panels used instead of cutting flat ledger panels at 45 degrees? Factory-made L-panels feature finished splitface stone on both outer faces, creating a seamless, natural corner. Miter-cutting flat panels on site leaves raw, untextured saw lines exposed at the corner joint. How do I stagger the corner L-panels during installation? Flip the corner pieces on alternating rows (row 1: long leg left; row 2: long leg right) so the vertical seams where corner pieces meet flat ledger panels are staggered naturally across the wall. Is Royal White natural marble frost-proof for cold outdoor climates? Yes, provided corner panels are installed using polymer-modified freeze-thaw rated white mortar, proper wall flashing to prevent water pooling behind the stone, and an exterior penetrating sealer.
