Installation & Handling Guidelines
⚠️ IMPORTANT: NATURAL STONE LEDGER PANEL INSTALLATION PROTOCOL
-
Substrate Structural Load Capacity: Marble ledger panels are heavy natural stone (approx. 8–10 lbs per sq. ft.). Ensure wall substrates (concrete, cement backer board, or masonry) are securely fastened to studs and structurally rated to carry heavy vertical stone loads.
-
Large & Heavy Tile (LFT) Mortar Selection: Install using a high-performance, polymer-modified Large & Heavy Tile (LFT) pure white thin-set mortar specifically rated for natural stone (ANSI A118.4 / ANSI A118.15). White mortar prevents dark shadowing behind translucent marble strips.
-
Tight-Joint Installation (No Grout): Interlocking Z-panels are engineered to be "dry-stacked" tight against one another without grout lines. Stagger horizontal panel joints in a running bond pattern to conceal seams.
-
Corner Configuration: Use matching MSI Rockmount Glacial Grey 6" x 12" x 6" "L" Corner Panels on 90-degree outside corners to eliminate exposed saw-cut stone edges.
-
Pre-Sealing & Maintenance: Apply a penetrating natural stone sealer after installation to protect against dirt accumulation and moisture absorption.
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.
-
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: Modern Coastal, Nordic Minimalist, Urban Executive, Modern Mountain.
-
Visual Advantage: Crisp ice-gray and silver tones bring a light-enhancing, neutral element to vertical walls while catching natural directional light.

Frequently Asked Questions
Does MSI Glacial Grey Ledger Panel require grout?
No. Ledger panel tiles are designed to interlocking-butt tightly together without grout lines, creating a continuous dry-stacked stone appearance.
Can Glacial Grey panels be installed around an outdoor grill or fireplace?
Yes! Natural marble ledger panels are non-combustible and weather-resistant, making them ideal for outdoor fireplaces, barbecue islands, and patio walls when installed over suitable exterior-grade substrates.
Why is white mortar recommended for installation?
Glacial Grey marble contains lighter, slightly translucent marble pieces. Using pure white LFT thinset prevents gray mortar from showing through or dulling the stone's bright gray-white body.
