The identification of a condition is the primary step in dealing with a condition. If the condition cannot be determined, there will be no way to proceed. Therefore, when you cannot directly judge the problem, you need to discuss more. Otherwise, it will be a fisherman and misguided. For example, there is a yellow stain on the facing stone. If there is no diagnosis, it will be treated with an acidic rust remover. Maybe the situation is getting worse and worse. When dealing with this disease, the problem may have changed. It is more difficult to deal with. Therefore, before dealing with problems, we must first do: 1. Correctly identify the type of facing stone: marble, granite, or other kinds of stone, and fully understand and understand the structure and composition of this stone. For example, if the stone which produces yellow stains mentioned above is marble, because it is alkaline, it cannot be treated with an acidic rust remover, otherwise it will corrode the surface of the stone. 2, determine the installation method of stone: how to install the stone, dry hanging method, glue method or wet paste method? You can gently tap the surface of the stone, judging the installation method of the stone from the sound. Generally, there is a crisp sound when the dry hanging stone is struck, and the wet plastering stone is dull. We can also consult directly with Party A. 3, determine the time of stone disease generation: fully understand the length of time the problem exists to provide a reliable basis for us to determine the severity of the disease and the correct selection of appropriate drugs and processes. If the stone is completely new, but there are many abrasion marks and a lot of dirty juice, perhaps because of the use of too soft stone and improper maintenance after the construction. For example, white sand beige is laid in the hall, and the above symptoms are prone to occur if it is not properly treated and maintained. If the wear is serious, it may only be refurbished. If a macula appears, we can consider using a macula scavenger instead of a rust remover. 4. Track current and past routine maintenance methods and materials: Does the stone have been maintained? How is it maintained? What kind of maintenance materials are used? How often do you clean it? Was it waxed? What technology is used? The answers to these questions are important before the illness is confirmed, and many stone problems are caused by improper maintenance methods. For example, the stone used to be waxed for maintenance, now may have been waxed many times, but the wax remover contains strong alkali, salt and other substances, if not fully washed, these destructive substances will remain in the stone capillary Inside, it will cause the appearance of pits or whole peeling of the stone surface. 5. Check the environmental conditions around the stone to determine whether the stone disease is related to the surrounding environment. If there is groundwater under the ground stone, there may be a lot of water spots, rust spots and alkaline substances on the surface. If we only deal with the surface, the disease will appear soon, and it will not be cured at all; The emergence of Chinese illness. Water is a deadly factor produced by Baihua, and it cannot be formed without water Baihua. The water source comes from two aspects: one is that the cement mortar has too much water when the stone is installed, and the other is that the wall leaks. Generally, Baihua is easily treated by cement mortar, and generally does not recur after treatment. However, the problem of whiteness caused by water leakage in the wall, if the problem of water leakage is not solved, the treatment of its symptoms will produce a vicious circle, and it is also futile. Therefore, it is necessary to judge whether the occurrence of stone disease is related to the surrounding environment before treating the disease.
