The material of the external wall is mainly glass curtain, composite aluminum plywood, marble, granite, mosaic, porcelain, dry sticky stone, water-brushed stone, etc. The erosion of dust, oil, and acid rain (fog) in the air often makes a new building dirty in a short period of time, especially in some cities with severe air pollution. Without regular professional cleaning and care, it will soon lose its original charming style, which will not only shorten the natural life of the external wall, but also greatly affect the city's beauty and image.

Our company has developed a series of external wall cleaning agents based on this situation. It is rich in surfactants, penetrants, wall-hanging agents, and uses the principles of penetration, dissolution, and emulsification to make the cleaned wall as clean and clean as possible (Checkerboard method) can reach more than 98%. Due to the successful use of wall-hanging technology, the wall surface will be free of oil and dust after cleaning.
The equipment for exterior wall cleaning is mainly high-altitude hanging baskets and high-altitude hanging plates. Hanging basket cleaning is generally not suitable for the start-up stage of a business due to the expensive equipment and high disassembly and transportation costs. The high-altitude hanging plate cleaning has the advantages of good safety, economical equipment, and easy installation and operation. At present, and for a long time, it will be the main method of cleaning the external walls of buildings in China. The main way to clean the curtain wall cleaning agent window contains a surfactant, the penetrant uses the principle of penetration, dissolution and emulsification cooperation, and the wall after cleaning is as smooth as ever. Decontamination rate can be more than 98%.
Because professional external wall cleaning agents usually contain anti-static and dust-proof ingredients, the surface of the wall surface after cleaning can be shiny and bright, and a protective film can be formed on the surface of the wall to prevent it from being easily contaminated by dust, thereby improving The protective ability of the external wall against the erosion of external harmful substances. The external wall is renovated. The external wall is painted. The external wall is waxed. The external wall is leaked. 1. The external wall tiles have many disadvantages. All have been changed to paint. The company has a professional team of exterior wall construction and construction technology, which can save you a lot of costs.
2. Construction of exterior wall coatings:
The bottom layer of the exterior wall coating of the building requires a sufficient curing period, and the new water-mortar concrete surface must pass a reasonable curing time to allow it to "spit out alkali" and fully dry. The surface of the bottom layer should be dry, solid and firm, and free from defects such as sand, cracks and looseness.
3. Construction method:
It is not advisable to scrape putty on a large area, and the putty layer is not too thick. The material is polymer cement putty. Generally use one coat of primer and two coats of top coating. The number of top coat passes can be appropriately increased according to the project quality requirements. The coating construction is generally carried out from top to bottom, and each pass of brushing should be divided by the dividing line, the wall, the junction of the yin and yang corners, or the downspout.
4. Maintenance and renovation:
The biggest advantage of using paint to decorate the building surface is that it can be renovated within a certain period of time. Generally, the building is comprehensively maintained within 4-5 years. Conduct a comprehensive and comprehensive inspection of the refurbished exterior wall surface before construction, and formulate a construction plan.
After finishing the painting project, we will carry out long-term quality tracking, return visits to customers, and provide painting maintenance programs.
5. Waterproofing and leak-proofing of high-rise walls The company's construction strengths are high-altitude operations, and there are professional and technical personnel for various types of waterproof repair projects to investigate, disassemble, and formulate construction plans. Therefore, scaffolding is not required for waterproof plugging of high-rise exterior walls, which saves auxiliary expenses.
