Is Direct Sunlight Harmful to Marble?

By Frederick M. Hueston

 

Marble is a beautiful and popular natural stone that is often used in building and home decor. However, it is also sensitive to certain environmental factors, such as direct sunlight. Over time, exposure to direct sunlight can cause marble to discolor, fade, and even develop cracks.

One of the main effects of direct sunlight on marble is discoloration. Marble is composed of calcium carbonate, which can react with sunlight and cause the color to change or fade. This can result in unsightly yellow or brown stains on the surface of the marble.

Another effect of direct sunlight on marble is the development of cracks. Marble is a relatively soft stone, and prolonged exposure to sunlight can cause the surface to dry out and become brittle. This can lead to the formation of cracks, which can weaken the structural integrity of the marble and make it more susceptible to damage.

In addition to discoloration and cracking, direct sunlight can also cause the surface of marble to become dull and lose its shine. This is because sunlight can cause the surface of the marble to become etched, which can dull the shine and make the marble look dull and faded.

To protect marble from the effects of direct sunlight, it is important to keep it out of direct sunlight whenever possible. This can be done by using window coverings, such as curtains or blinds, to block out the sun's rays. It is also important to regularly clean and polish the marble to maintain its shine and protect the surface from etching.

In conclusion, direct sunlight can have a detrimental effect on marble, causing discoloration, cracking, dulling and etching. To protect marble from these effects, it is important to keep it out of direct sunlight and maintain proper care and cleaning.
