What is a major consideration when using natural stone tiles?

When using natural stone tiles, a significant consideration is the need for sealing to prevent staining. Natural stone, such as granite, marble, and limestone, is porous, which means it can absorb liquids and potentially stain if not properly treated. Sealing the tiles creates a protective barrier that helps to minimize the absorption of spills, dirt, and other substances, thus maintaining the aesthetic and functional qualities of the stone over time.

In addition to staining, sealing can also protect the stone from wear and reduce the risks of degradation from moisture, which is particularly important in high-humidity areas like bathrooms and kitchens. Without sealing, natural stone can become discolored or damaged, resulting in costly repairs or replacements.

While other factors such as texture, weight, and the size of the installation area are important, they do not directly address the inherent vulnerability of natural stone tiles to staining. Therefore, understanding the necessity of sealing is crucial for ensuring the longevity and beauty of natural stone tile installations.
