This is the "Seamless Guardian" of the collection. While standard corner solutions often require complex mitering or leave an exposed "raw" edge, the XL California Gold 9x18 Corner Panel provides a pre-fabricated, 90-degree wrap-around. It is the premier choice for a "Rustic Estate" or "High-End Lodge" aesthetic, prioritizing an unbroken, monolithic transition around columns, fireplace edges, and exterior corners

PRODUCT TITLE

XL Rockmount™ Series: California Gold 9" x 18" Split-Face Slate Corner Panel

PRODUCT DESCRIPTION

Ensure a professional, high-end finish for your stonework with the XL California Gold Corner. Crafted from the same premium natural slate as the matching 9x24 flat panels, these "L-shaped" pieces are designed to wrap seamlessly around outside corners. By using a pre-made corner, you eliminate the visual "seam" that typically occurs when two flat panels meet, making your wall look like it was built from massive, solid blocks of stone rather than thin veneers.

The XL Series features larger individual stone pieces compared to standard ledger panels, resulting in a cleaner, more contemporary look with fewer visible joints. The California Gold palette is legendary for its "High-Variation" beauty—a rich, earthy tapestry of rusty copper, deep charcoal-greys, and warm honey-golds. Whether finishing an outdoor kitchen island or a grand indoor hearth, these corners provide the necessary architectural weight and detail to complete the project.

KEY FEATURES

• L-Shaped Seamless Transition: Specifically engineered to wrap around 90-degree outside corners without visible joints or mitering.

• XL Grand Scale: Features larger stone chips for a more authentic, heavy-masonry appearance compared to standard 6" height ledger panels.

• Premium Natural Slate: A rugged, "split-face" texture that showcases the natural cleft and mineral shimmer of the stone.

• Interlocking "Z" Design: The panels are cut to interlock, hiding vertical seams and ensuring a continuous flow of stone.

• Indoor/Outdoor Versatility: Frost-resistant and durable enough for exterior retaining walls, yet refined enough for interior accent walls.

SPECIFICATIONS

INSTALLATION REQUIREMENTS

⚠️ CRITICAL: Natural slate is heavy and contains crystalline silica. You must use a High-Bond, Polymer-Modified Thin-set rated for natural stone. Only use a wet saw for cuts to prevent hazardous airborne dust (Prop 65).

Manufacturer Recommendations:

• Corner-First Rule: Always start each row at the outside corner and work your way toward the center of the wall. This ensures the most important architectural detail is perfectly aligned.

• Alternating Orientation: To prevent a vertical "zipper" line, rotate the corner panels 180° for every other row (alternating the long and short legs of the "L").

• Substrate Strength: Ensure your wall is cement board or masonry. This stone weighs over 12 lbs per square foot and requires a structural substrate that won't sag under the weight.

FREQUENTLY ASKED QUESTIONS

• How many do I need? Measure the total linear feet of your outside corner. Since each panel is 9" (0.75 ft) tall, divide your total height by 0.75 to get the number of pieces required.

• Does it need grout? No. These are designed for a "dry-stack" look. The panels nest together tightly to hide the wall behind them.

• Is it okay for a fireplace? Yes, it is heat-resistant. It is the gold standard for creating a "floor-to-ceiling" stone hearth.

PRO INSTALLATION TIPS

• The "Color Blend" Shuffle: California Gold has high variation. Open all boxes of both corners and flat panels at once. Shuffle them to ensure the "rusty" pieces and the "grey" pieces are evenly distributed.

• Back-Buttering: Apply thin-set to the back of the corner panel and the wall. This is critical for corners, as they are often bumped or kicked in high-traffic areas.

• Wall-Wash Lighting: Use downward-facing LED spotlights to highlight the 1.5" depth of the split-face texture. The shadows created by the jagged edges of the slate are spectacular at night.
