Problems that should be avoided in stone application

For more than 20 years, with the great development of my country's construction industry, the stone industry has become increasingly prosperous. With its irreplaceable advantages, decorative stone has become the third largest building material after cement and steel. Almost all large-scale buildings in China are more or less Few decorative stones are used. The stone makes the building look simple and natural, solemn and luxurious, and greatly improves the quality of the building. At the same time, the problems in the application of stone are gradually exposed.

Wet paste with cement mortar without any protective treatment on the stone

　　 Water spots, white flowers and rust spots abound, and many people even think that these lesions are normal phenomena that cannot be avoided. With the advent of advanced protective materials and new installation techniques, methods to prevent these lesions are gradually being promoted. However, some old concepts are difficult to change, some old crafts are still in use, and the use of new materials has not been fully mastered, and the new technology is not perfect, etc., causing various stone lesions to continue to appear.

Do not pay attention to cleaning and daily care

　　 At present, more than 90% of stone cleaning and daily care work are completed by numerous cleaning teams. Most of the cleaning staff have been transferred from other cleaning industries in recent years, and it is only in recent years that the cleaning and maintenance of stone have been taken into account. They do not have enough knowledge of the characteristics of the stone and the methods of using different stones. They often do not master the use of special cleaning and care materials for the stone. Some even use toilet materials or carpet washing methods to clean the stone. Therefore, it will inevitably cause various problems. Not only the old lesions are difficult to remove, but the new lesions appear again, and even cause a loss of millions of yuan in a single project.

Use inferior stone protective agent

　　 When propagating and promoting the concept of "prevention is better than cure", some low-quality protective agents took the opportunity to flood. Some protective agent advertisements are fascinating. They do not pay attention to specific stone characteristics and specific application environments. Instead, they use some plausible operation methods that are not too simple. In reality, various diseases caused by improper selection and use of stone protective agents can often be seen. For example, the old water spots are not eliminated, but more serious new water spots appear, large areas of yellowing or whitening, etc., and such lesions are often more difficult to remove due to the protection of protective agents.
