Nothing adds instant warmth, luxury, and a sense of timelessness like a genuine copper mosaic tile splashback. It’s a bold choice that acts as the centerpiece of any room.

However, many customers hesitate, concerned about maintenance, cleaning, or tarnishing. The truth is, copper is a durable, unique, and incredibly low-maintenance material—once you understand its few basic needs.

Here is your complete guide to installing, cleaning, and caring for your ExoTiles copper mosaics.

1. Embracing the Patina: Is It Tarnish or Character?

The most defining feature of copper is its patina—the thin, protective layer that forms on the surface as it reacts to air, moisture, and time (oxidation).

• It’s Normal: The beautiful green or darker brown shades that copper eventually develops are not flaws; they are a sign of genuine copper aging naturally.

• The Choice is Yours: You have two options for your copper tiles:

  1. Maintain the original shine (requires sealing and careful cleaning).

  2. Allow the natural patina to develop (requires virtually no special maintenance). Most customers choose the second option, as the aged look is part of the appeal.

2. Installation Tips for Copper Mosaics

Copper mosaic sheets require a few special considerations compared to glass or porcelain:

Step	Standard Tile Tip	Copper Tile Requirement
Grout	Use standard or epoxy grout.	Strictly use NON-SANDED Grout. Sand will scratch the delicate metal surface during installation. Epoxy is highly recommended for commercial or wet areas.
Cuts	Use a wet saw.	Use Tin Snips or Tile Nippers. Do not use a saw, as the friction will damage the metal face.
Sealing	Optional for non-porous tiles.	Highly Recommended. Apply a metal sealer (lacquer) before grouting to protect the original finish, especially if you want to delay or prevent patina formation.

3. The Essential Care and Cleaning Guide

For daily cleaning, less is always more with copper. The key is to avoid harsh acids or abrasive tools.

• Daily Cleaning: Simply wipe the surface with a soft, damp cloth (microfiber is best) and warm water. Dry immediately to prevent water spots, particularly in hard water areas.

• Deep Cleaning: Use a mild, pH-neutral soap (like dish soap) diluted heavily with water. Spray onto the surface, let it sit for a minute, and wipe clean.

• DO NOT Use:

  • Vinegar or lemon juice (harsh acids accelerate oxidation in an uncontrolled way).

  • Ammonia or bleach.

  • Abrasive scrubbing pads, steel wool, or hard brushes.

To Restore Shine: If you want to return the tile to its original, bright shine, use a specialized copper polish. However, be aware this removes the protective patina, and the tile will begin aging again immediately.

4. Where Copper Excels: Commercial & Residential Use

Copper mosaics are surprisingly durable and stand up well to high-traffic areas, making them ideal for:

• Kitchen Splashbacks: They provide stunning contrast with white or black stone countertops and are highly heat resistant.

• Feature Walls/Fireplace Surrounds: The material is inherently warm, creating a natural focal point in a living space.

• Retail/Café Counters: In commercial spaces, the material’s unique look and high-end feel are perfect for making a memorable impression on customers.
