🏛️ THE DESIGN IDENTITY

• The Archetype: The Monolithic Nordic Ledger Keystone for seamless, heavy-gauge natural stone corner transitions.

• The Contrast: Unlike standard 6" x 24" flat veneer cuts that leave awkward vertical joints or exposed raw backing on outside corners, the XL Rockmount "L-Shaped" Corner Panel delivers a staggered, interlocking 90-degree wrap with natural splitface stone texture across both planes.

• Design Aesthetics: The premier corner detail for Modern Alpine Lodge, Earthy Minimalist, Contemporary Craftsman, and Luxury Outdoor Living hardscapes.

• The Mineral Field: Crafted from genuine natural marble/quartzite—blending frosty silver-grays, soft pewter, crisp white crystalline veining, and subtle slate undertones.

• The Visual Flow: The oversized "XL" profile features wider, bolder individual stone strips that minimize horizontal joint lines, creating an expansive, architecturally grand stone column or exterior wall return.

🏷️ PRODUCT TITLE

Rockmount XL Series: 9" x 12" x 6" Alaska Gray Splitface Natural Stone Corner Panel

📝 PRODUCT DESCRIPTION

Achieve a continuous, authentic stacked stone look on 90-degree outside corners with the 9" x 12" x 6" XL Rockmount Alaska Gray Corner Panel. Specially pre-assembled into an L-shape, this specialized corner ledger panel solves the challenge of terminating stone veneer runs along exterior house corners, fireplace surrounds, outdoor kitchen islands, and structural pillars.

Crafted from natural marble/quartzite splitface stone, the Alaska Gray palette features a sophisticated blend of icy grays, mid-tone pewter, and subtle white veining. Its raw, hand-split texture interacts dynamically with natural sunlight and directional spotlighting. Part of the XL Rockmount collection, the enlarged stone format provides a more substantial, rugged appearance with fewer visible seams compared to traditional standard ledger panels.

✨ KEY FEATURES

• Pre-Assembled L-Shaped Corner: Interlocking 9" x 12" x 6" layout wraps 90-degree outside corners seamlessly without requiring miter cutting or corner trim metal.

• Extra-Large (XL) Format: Features wider individual stone strips for a bolder, more substantial architectural stone veneer presentation.

• 100% Genuine Splitface Natural Stone: Hand-cut marble/quartzite provides authentic textural depth and natural crystalline sparkle.

• Indoor & Outdoor Rated: Weather-resistant and freeze-thaw stable for outdoor exterior facades, retaining walls, indoor fireplaces, and feature walls.

• Dry-Stack Installation: Designed to fit tight without exposed grout joints, creating a clean, modern stacked stone aesthetic.

🛠️ INSTALLATION REQUIREMENTS

⚠️ CRITICAL WARNING: WEIGHT LOAD & CORNER-FIRST LAYOUT

• Corner-First Setting: Always set corner panels first working from the bottom up, alternating long and short legs on successive rows to stagger joints. Then, slide straight 6" x 24" flat ledger panels flush against the corner pieces.

• Heavy-Duty Mortar Required: Because natural stone ledger panels carry significant weight, use a high-performance Polymer-Modified Medium Bed Mortar or ANSI A118.15 Thinset to prevent sagging.

• Substrate Integrity: Install over cement backer board, concrete block, or prepared cementitious scratch coat. Never install directly over drywall or painted surfaces without proper prep/lath.

Manufacturer Recommendations

• Recommended Joint Style: Dry-stacked (tight fit with no grout lines required).

• Sealing Requirements: Apply a breathable, penetrating stone sealer (natural finish or color-enhancing) to protect outdoor stone from dirt, moisture, and freeze-thaw spalling.

• Dry-Fit Check: Dry-lay corner pieces prior to installation to alternate light and dark tone variations evenly up the corner column.

💡 PRO INSTALLATION TIPS

1. Alternate Long and Short Legs: Flip the orientation of each corner panel on every row (12" leg left on row 1, 12" leg right on row 2) to eliminate vertical seams running straight up the corner.

2. 100% Mortar Back-Butter Contact: Apply thinset directly to the substrate and back-butter each corner panel to ensure complete mortar coverage and maximum mechanical bond.

3. Corner Support Board: Use temporary ledger boards screwed into the base of the wall to keep the first row perfectly level and supported while the mortar cures.

💬 FREQUENTLY ASKED QUESTIONS

Q: What is the purpose of an L-shaped ledger corner panel?

A: An L-shaped corner panel wraps around an outside 90-degree corner, hiding the cut ends of the stone and making the wall look like it was constructed with full-depth, dimensional building stone.

Q: Can this Alaska Gray XL corner panel be used outdoors around a pool or barbecue island?

A: Yes. Made of dense natural marble/quartzite, it is fully rated for exterior walls, barbecue islands, retaining walls, and outdoor fireplaces in all climates.

Q: How many corner panels do I need to order?

A: Calculate the total vertical linear feet of outside corner you need to cover. Since each panel is 6 inches high (0.5 feet), multiply the total vertical height by 2 to determine the number of corner pieces needed. Add 10% extra for job-site trimming.
