MSI Tundra Gray 16" × 24" × 5 cm Marble Pool Coping

Product Overview

Tundra Gray Marble Pool Coping in 16" x 24" format provides a clean, substantial edge for swimming pools, spas, steps, raised walls, and other outdoor architectural features. Each piece measures approximately 5 cm thick—nearly 2 inches—with one long side finished in a smooth bullnose profile.

The stone’s soft gray background and subtle natural movement create a calm, neutral appearance that complements both traditional and modern outdoor spaces. Its large rectangular format produces fewer joints and a streamlined perimeter around pools and hardscape areas.

Because Tundra Gray is natural marble, variations in shade, veining, fossils, texture, and surface character are expected. These variations are part of the stone’s natural beauty and make every installation unique.

Recommended Applications

• Swimming pool perimeters

• Spa and hot-tub surrounds

• Pool steps and raised edges

• Outdoor stairs and landings

• Seat walls and retaining-wall caps

• Fountain and water-feature edges

• Landscape and hardscape details

The 5 cm thickness gives the coping a substantial architectural profile, while the bullnosed long edge creates a smooth transition at exposed pool and spa edges.

Technical Specifications

Nominal dimensions may vary slightly due to the natural material and fabrication process.

Installation and Handling Guidelines

Inspect and Blend Before Installation

Inspect all pieces before installation. Dry-lay coping from multiple crates or pallets to blend natural shade and veining variations. Confirm the direction of every bullnosed edge before permanently setting the pieces.

Prepare the Substrate

The setting surface must be structurally sound, clean, properly waterproofed, and suitable for exterior natural-stone installation. Pool coping requires careful substrate preparation, drainage, waterproofing, movement accommodation, and joint placement.

Use an Exterior-Rated Setting Material

Install with a high-performance setting mortar approved for natural marble, exterior exposure, submerged or intermittently wet environments, and the specific substrate. Light-colored or white mortar is generally recommended to minimize the possibility of affecting the stone’s appearance.

Maintain Consistent Joints

Provide consistent joints between coping pieces and include movement joints where required by the project design and applicable installation standards. Do not install coping pieces tightly against one another.

Seal the Stone

Apply a breathable penetrating sealer formulated for exterior natural stone. Test the sealer on a spare piece or inconspicuous area before treating the entire installation. Sealing can help reduce water and stain absorption but will not make marble stain-proof.

Confirm Climate Suitability

Natural stone performance can vary by climate and installation method. For projects exposed to repeated freeze-thaw cycles, saltwater systems, deicing chemicals, or severe weather, confirm suitability with the installer, architect, or stone professional before installation.

Professional installation by a contractor experienced with natural-stone pool coping is strongly recommended.

Care and Maintenance

Clean the coping with fresh water and a soft brush or cloth. For deeper cleaning, use a pH-neutral cleaner specifically formulated for exterior natural stone.

Avoid acidic cleaners, vinegar, muriatic acid, abrasive powders, bleach, and harsh pool-deck chemicals. Improper chemical use may etch, discolor, or damage natural marble.

Keep pool-water chemistry properly balanced and rinse chemical spills or concentrated chlorinated water from the stone promptly. Reseal periodically according to exposure, traffic, climate, and the sealer manufacturer’s recommendations.

Frequently Asked Questions

What are the dimensions of this Tundra Gray pool coping?

Each coping piece measures approximately 16" x 24" and is 5 cm thick, which is approximately 2 inches.

Which edge is bullnosed?

One 24-inch-long exposed edge has a smooth bullnose profile. Confirm the orientation of every piece during dry layout and before installation.

Can this coping be used around a saltwater pool?

Potentially, but performance depends on the stone, sealer, water chemistry, climate, and installation system. Consult an experienced natural-stone pool installer before using it with a saltwater system.

Does Tundra Gray marble need to be sealed?

Sealing is recommended for exterior pool environments. Use a breathable penetrating sealer intended for natural marble and test it before application.

Will every coping piece match exactly?

No. Tundra Gray is a natural stone, so color, veining, fossils, and texture will vary. Blend pieces from different crates or pallets before installation for a balanced appearance.
