Marble is a highly sought-after natural stone known for its elegance and timeless appeal. However, sometimes after installation, marble surfaces can undergo color changes. Understanding the reasons behind this discoloration can help maintain the marble’s aesthetic value.
1. Exposure to Sunlight
One of the primary causes of color change in marble is prolonged exposure to direct sunlight. UV rays can cause the stone’s natural pigments to fade, resulting in a lighter or yellowish appearance over time.
2. Moisture and Humidity
Moisture is another factor that can affect marble. When water seeps into the stone, it can alter the color, especially if the marble is not sealed properly. Humidity can also contribute to surface discoloration.
3. Acidic Substances
Spilling acidic substances like lemon juice, vinegar, or cleaning products on marble can lead to chemical reactions that cause stains or color shifts. Acidic substances can erode the stone’s surface, affecting its natural shine and hue.
4. Natural Aging
Like many natural stones, marble changes with age. Over time, the mineral composition and natural wear and tear can lead to slight color variations.
5. Inadequate Sealing
If marble is not adequately sealed, it can absorb stains from oils, food, or cleaning chemicals, leading to discoloration.
Proper care, including sealing, avoiding exposure to harsh chemicals, and regular cleaning, can prevent unwanted color changes in marble, preserving its natural beauty for years.
