Marble, a luxurious and timeless natural stone, is often used in both indoor and outdoor applications. However, prolonged sun exposure can significantly impact its appearance and structural integrity.

Effects of Sun Exposure on Marble

1. Discoloration: UV rays can cause marble to fade or develop uneven color changes over time, especially in darker varieties.

2. Thermal Stress: Repeated heating and cooling may lead to micro-cracks or surface deterioration.

3. Loss of Polish: Direct sunlight can accelerate the wear of polished finishes, making the surface appear dull.

How to Protect Marble from Sun Damage

- Sealing: Apply a high-quality UV-resistant sealer to minimize discoloration.

- Shading: Use awnings, pergolas, or umbrellas to reduce direct sunlight exposure.

- Regular Maintenance: Clean with pH-neutral products and reapply sealant annually.

While marble is durable, proactive care ensures its longevity and beauty even under harsh sunlight. Choose lighter-colored marble for outdoor use, as it shows fading less noticeably.
