The Important Role Of Putty Spraying Machine And Waterproof Coating Spraying Machine In Construction

In the past, when the waterproof coating was applied on the construction site, the usual method was to stir it on site, and then manually brush or roll it. Mechanical spraying with putty sprayer or waterproof coating sprayer was rare. In today's society, changes in efficiency mean increased benefits. Therefore, during the peak period of the project, the construction party arbitrarily reduces the construction process in order to rush to the schedule, resulting in frequent project quality accidents. Therefore, traditional manual scrubbing can no longer keep up with the construction progress. At present, the operation level of waterproof coating spraying equipment has not been widely used in engineering. Therefore, the development and promotion of waterproof coating spraying equipment is of great significance for improving spraying efficiency and improving spraying level. The operation method of the waterproof paint spraying machine is simple and convenient, which greatly reduces the heavy manual labor of the waterproof spray paint workers in the building construction, and the work efficiency can be increased by 50%-60%. In addition, the rational use of paint and the reduction of paint waste are also of great significance. At present, we have a wealth of on-site construction experience. Qualified waterproof materials, professional surface treatment of the base layer, correct equipment selection and reasonable construction techniques are the key links for a good waterproof layer. Here is a brief introduction:

Simple basic treatment: only need to be cleaned, no foreign matter, floating dust, dust on the surface of the basic layer, water quick-setting rubber asphalt waterproof coating, JS, acrylic, polyurethane waterproof coating, polyurethane hard foam, methyl methacrylate all belong to this category.

Complex base treatment: It is necessary to perform processes such as shot blasting to clean up laitance, putty leveling, primer coating and sealing. Polyureas fall into this category. Wet-to-wet continuous spraying can reach the thickness at one time: quick-setting rubber asphalt waterproof coating, acrylic, polyurethane waterproof coating and methyl methacrylate fall into this category. Before spraying, you need to wait for a cure to reach the thickness: JS waterproof coating, polyurethane rigid foam and polyurea belong to this category.
