This is the luminous "Pristine Modern" of the collection. While the darker "Peak" series captures the rugged shadows of the mountains, XL Arctic White captures the brilliant, clean-cut energy of a glacial landscape or a high-end minimalist gallery. It is the perfect choice for a "Scandi-Luxe" or "Modern Coastal" aesthetic that prioritizes brightness, vertical scale, and a sharp, seamless finish.

PRODUCT TITLE

XL Series: Arctic White 9" x 18" RockFace Corner Panel

PRODUCT DESCRIPTION

Complete the structural narrative of your design with the XL Arctic White Corner Panel. This premium natural marble ledger corner is a masterful study in brilliance, featuring an "L-shaped" design that wraps around outside corners to eliminate visible seams and provide a solid, monolithic appearance.

The XL Arctic White is designed to create a sophisticated, "stacked-ice" effect. When used on exterior columns, fireplace surrounds, or interior feature corners, the oversized 9-inch height offers a more modern, expansive look than standard ledger sizes. Engineered from high-density Marble, this rockface corner provides a rugged, crystalline depth that ensures your masonry looks authentic and unified from every angle, reflecting light with a subtle, natural shimmer.

KEY FEATURES

• Ultra-Bright Arctic Palette: A crisp, crystalline white that provides a high-impact, clean foundation for modern and transitional designs.

• Seamless L-Shaped Design: A pre-fabricated corner that wraps 90-degree angles, creating the illusion of full-depth stone blocks rather than thin veneers.

• Oversized XL Format: The 9-inch height reduces the number of horizontal joints, creating a cleaner, more upscale visual rhythm.

• Hand-Split RockFace Texture: The jagged, crystalline surface catches light on both faces of the corner, adding architectural drama and texture.

• Natural Marble Composition: Authentic, high-quality stone that offers a unique "thumbprint" of nature on every single piece.

INSTALLATION REQUIREMENTS

⚠️ CRITICAL: To protect the brilliant white color of the marble, you must use a White Large-and-Heavy-Tile (LHT) Mortar. Using a standard grey mortar will "shadow" through the white stone, causing it to look dull or muddy over time. Additionally, this stone must be sealed prior to installation to prevent mortar staining.

Manufacturer Recommendations:

• Recommended Mortar: A premium white polymer-modified mortar (such as MAPEI Ultralite S2 White) to ensure maximum bond strength and color purity.

• Grout Requirement: Dry Stack Only. These corners are designed to interlock tightly with the 9" x 18" flat panels without grout lines.

FREQUENTLY ASKED QUESTIONS

• Do I need these for inside corners? No. Inside corners are typically done by "butt-joining" two flat panels. These L-shaped units are specifically for outside corners (columns, bump-outs, fireplace ends).

• How many do I need? Since each piece is 9" high, you will need 1.33 pieces for every 1 foot of vertical height (e.g., 12 pieces for an 8-foot tall corner).

• Is this stone suitable for exterior use? Yes, but being natural marble, it is recommended to use a high-quality UV-resistant sealer to protect the white finish from environmental staining.

PRO INSTALLATION TIPS

• Start at the Corner: Always level and set your corner pieces first, then work your flat panels outward. This ensures the most visible part of the wall is perfectly plumb and aligned.

• The "Zig-Zag" Stack: Alternate the direction of the long and short sides as you go up the wall (Long-Short, then Short-Long). This staggers the vertical joints and makes the corner look like solid, hand-stacked stone.

• Back-Buttering is Key: Because of the irregular "L" shape and weight, always apply a layer of mortar to the back of the corner piece to ensure 100% coverage and a permanent bond.
