In the past, when applying waterproof coatings on construction sites, the typical approach was to mix the material on-site and then apply it manually by brushing or rolling; mechanical spraying using putty sprayers or dedicated waterproof coating sprayers was rare. In today’s society, improved efficiency translates into greater profitability. Consequently, during peak project phases, contractors often cut corners and streamline procedures in an effort to accelerate progress, leading to a surge in quality‑related incidents. As a result, traditional manual application can no longer keep pace with modern construction schedules. At present, the operational expertise required for waterproof coating spray equipment has yet to be widely adopted in the industry.

In the past, when applying waterproof coatings on construction sites, the typical approach was to mix the material on-site and then apply it by hand using a brush or roller, or with a putty sprayer. Mechanical spraying with waterproof coating sprayers is relatively rare. In today’s society, improvements in efficiency translate into greater profitability. Consequently, during peak construction periods, contractors often cut corners by skipping or streamlining procedures in an effort to meet tight deadlines, leading to a surge in quality‑related accidents. As a result, traditional manual brushing can no longer keep pace with the demands of modern construction schedules. At present, the operational expertise required for waterproof coating spray equipment has yet to be widely adopted in the industry; therefore, developing and promoting such equipment is crucial for boosting spraying efficiency and elevating overall application standards. The waterproof coating sprayer is easy and convenient to operate, significantly reducing the heavy manual labor involved in waterproof painting on construction sites and substantially increasing productivity. 50%-60% In addition, making efficient use of coatings and minimizing waste is of great importance. At present, we possess extensive on-site construction experience. Qualified waterproofing materials, professional substrate preparation, appropriate equipment selection, and sound application techniques are all critical factors for achieving a high‑quality waterproofing layer. Here is a brief overview:

Simple substrate preparation : Simply clean the substrate; ensure the surface is free of foreign matter, loose dust, and debris. Apply a fast‑setting rubberized asphalt waterproof coating. JS Acrylics, polyurethane waterproof coatings, rigid polyurethane foam, and methyl methacrylate all fall into this category.

Complex substrate preparation: Requires shot blasting to remove laitance, putty leveling, application of primer and seal coat, among other steps. Polyurea falls into this category. Wet-on-wet continuous spraying can achieve the desired thickness in a single pass; fast‑setting rubberized asphalt waterproofing coatings, acrylics, polyurethane waterproofing coatings, and methyl methacrylate coatings belong to this group. Prior to spraying, it is necessary to wait for the previous layer to cure fully before applying the next coat to reach the specified thickness. JS Waterproof coatings, polyurethane rigid foam, and polyurea belong to this category.
