For over 20 years, with the rapid development of China's construction industry, the stone industry has become increasingly prosperous. Decorative stone, with its irreplaceable advantages, has become the third largest building material after cement and steel. Almost all large buildings in China have adopted decorative stone to varying degrees. Stone makes buildings appear quaint, natural, solemn, and luxurious, greatly enhancing their quality. At the same time, problems that arise in the application of stone materials are gradually being exposed.
1.The stone was adhered using wet cement mortar without any protective treatment
Water spots, white spots, and rust spots are common, and many people even believe that these lesions are unavoidable and normal phenomena. With the emergence of advanced protective materials and new installation processes, methods to prevent these lesions are gradually being promoted. However, some outdated concepts are difficult to change, some outdated techniques are still in use, and the use of new materials has not been fully mastered, and new technologies are not yet perfect, resulting in various stone lesions still appearing.
2. Not paying attention to cleaning and daily care
Currently, over 90% of stone cleaning and daily care work is carried out by numerous cleaning teams. Most cleaning professionals have switched careers from other cleaning industries in recent years, and balancing stone cleaning and maintenance has only been a recent task. They lack understanding of the characteristics of stone and the usage methods of different types of stone. They often have difficulty mastering the use of specialized cleaning and care materials for stone, and some even use methods such as cleaning bathroom materials or carpet cleaning to clean stone. Therefore, it is inevitable that various problems will arise, not only are old lesions difficult to remove, but new lesions will also appear, even causing losses of millions of yuan in individual projects.
3. Using inferior stone protective agents
When promoting the concept of "prevention is better than cure", some inferior protective agents have taken advantage of the situation and become rampant. Some protective agent advertisements are exaggerated, without paying attention to the specific characteristics and application environment of the stone, and using some seemingly simple operation methods. In reality, various pathological phenomena caused by improper selection and use of stone protective agents can often be seen. For example, if the old water spots are not eliminated, more severe new water spots may appear, such as large areas of yellowing or whitening, which are often more difficult to remove due to the protection of protective agents.
