For over two decades, the rapid development of China's construction industry has significantly boosted the stone sector, making it one of the most dynamic and essential parts of modern architecture. As the third-largest building material after cement and steel, decorative stone is now widely used in almost all large-scale buildings. It adds a sense of natural elegance, sophistication, and grandeur to structures, greatly enhancing their visual appeal and overall value. However, as its usage expands, challenges in the application and maintenance of stone have also become more apparent.
One major issue is the improper installation techniques, such as using wet cement mortar without applying any protective treatments to the stone. This leads to problems like water stains, efflorescence, and rust spots, which many people mistakenly believe are unavoidable. Fortunately, with the introduction of advanced protective materials and improved installation methods, solutions to these issues are becoming more accessible. Yet, outdated practices and traditional methods still persist, and some professionals remain unaware of the benefits of new technologies. This lack of knowledge and adoption can result in recurring stone-related problems.
Another significant concern is the neglect of regular cleaning and maintenance. Over 90% of stone care is handled by cleaning teams that often come from other industries. These workers usually lack proper training on the specific characteristics of different types of stone and the appropriate cleaning products to use. Many resort to using inappropriate materials, such as bathroom cleaners or carpet shampoos, which can cause serious damage. As a result, existing stains become harder to remove, and new ones frequently appear, sometimes leading to costly repairs—up to millions of yuan in certain cases.
Additionally, the use of low-quality stone protectants has further complicated the situation. While the idea of "prevention before treatment" has gained traction, some inferior products have flooded the market. These products often promise quick fixes without considering the unique properties of the stone or the environmental conditions in which they will be applied. Some even employ misleadingly simple procedures that don’t deliver real results. In practice, this has led to worsening conditions, such as intensified water stains, yellowing, or whitening of the stone, which are difficult to reverse once the protective layer is in place.
To ensure the longevity and beauty of stone surfaces, it’s essential to adopt proper installation, maintenance, and protection strategies. With the right knowledge and tools, many of these issues can be avoided, preserving the aesthetic and structural integrity of stone in modern architecture.
