Product Overview
Mayra White 9" x 12" x 6" XL Corner L Panel (Pre-Assembled L-Corner) brings timeless Mediterranean elegance, continuous seam integration, and seamless wall wrapping to luxury indoor and outdoor architectural features. Crafted from authentic Egyptian limestone, Mayra White showcases a soft pale ivory and cream background with subtle fossilized shell details, light natural veining, and gentle mineral warmth.
The precision-engineered L-corner design eliminates the need for unsightly mitering, exposed raw joints, or complex field cutting on structural turns. Featuring a hand-split or textured natural face and a substantial thickness, this structural corner unit provides a monolithic, stone-masonry appearance for pool feature walls, fireplace surrounds, outdoor kitchen pillars, and retaining wall transitions.

Recommended Applications
-
Pillars, Columns & Exterior Posts: Wraps 90-degree corners cleanly, giving structural support columns and entryway posts a continuous, authentic full-bed stone appearance.
-
Fireplace Surrounds & Outdoor Kitchen Islands: Delivers seamless corner transitions on vertical veneer walls, outdoor BBQ islands, and indoor/outdoor fireplace builds.
-
Retaining Wall Ends & Raised Pool Feature Walls: Frames raised water features, pool planters, and retaining wall corners with clean, pre-engineered 90-degree joint alignment.
Installation & Handling Guidelines
⚠️ IMPORTANT: NATURAL LIMESTONE VENEER CORNER PROTOCOL
-
Setting Mortar Selection: Install L-panels 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 through light limestone body.
-
Substrate Preparation: Install over clean, structurally sound, and level concrete masonry unit (CMU) walls, cement backer board, or scratch-coated metal lath systems. Ensure full adhesive suction.
-
Alternating Corner Stagger: Alternate the long (9") and short (12") legs on consecutive vertical courses to break up continuous vertical seams and establish a natural, hand-laid stone pattern.
-
Back-Butter Coverage: Fully back-butter the rear of every corner panel to achieve 100% mortar coverage, eliminating air pockets that could trap moisture and lead to freeze-thaw spalling.
-
Penetrating Stone Sealer Required: Apply a high-quality penetrating natural stone sealer specifically formulated for outdoor elements after installation to protect against efflorescence, water absorption, and staining.
Care & Maintenance
-
Routine Cleaning: Rinse periodically with low-pressure fresh water or clean using a neutral pH natural stone cleaner and a soft bristle brush.
-
Avoid Acidic Cleaners: Never use muriatic acid, acidic tile cleaners, or harsh chemicals on natural limestone, as acids will react with and dissolve the calcium carbonate stone structure.
-
Periodic Resealing: Reapply a penetrating stone sealer every 2 to 3 years depending on exposure to salt water, high moisture, or harsh weather environments.
Design Profile
-
Aesthetic Inspiration: Modern Mediterranean, French Country Estate, Coastal Contemporary, Resort-Style Architecture.
-
Visual Advantage: Soft ivory tones create deep shadow lines and dimensional texture without absorbing high solar heat, softening intense sunlight across large vertical walls.
-
Complementary Finishes: Integrates seamlessly with Mayra White 12" x 24" Pool Coping, Mayra White flat wall panels, light travertine decking, and natural timber accents.
Frequently Asked Questions
Why use pre-assembled XL L-Corner panels instead of field-mitering flat panels?
Pre-assembled L-corners eliminate the need for difficult, time-consuming 45-degree field mitering on site. They create a clean, natural 90-degree return that mimics thick, full-bed structural masonry while saving significantly on installation labor.
How do I hide vertical seams when stacking Mayra White Corner L Panels?
Alternate (stagger) the long 9" leg and short 12" leg direction on every course as you move up the wall. Interlocking the short and long legs prevents a straight vertical seam line from running up the corner.
Can Mayra White XL Corner Panels be used in wet or submerged environments?
They are ideal for pool feature walls, outdoor showers, and raised water features. However, they should not be continuously submerged underwater, and proper waterproofing membranes and penetrating sealers must be used during installation.
