High-speed rail construction began in 2008, marking the first large-scale application of specialized equipment in China’s building waterproofing industry. During this period, many companies sought to use waterproof coating spray‑applied equipment for two main reasons: First, two technologies employed in CRTS-type high-speed railways utilize polyurea as the waterproofing material for bridge decks. Because polyurea is a two‑component reactive coating with an extremely rapid curing time—hardening within just a few tens of seconds—it cannot be applied manually. Second, the extensive development of high-speed rail projects has resulted in numerous waterproofing construction tasks. For example, the Beijing–Shanghai High-Speed Railway alone involves more than 1…

High-speed rail construction began in 2008 In that year, China’s building waterproofing industry witnessed the first large-scale adoption of specialized equipment. During this period, many companies sought to use waterproof coating spray‑applying machines for two main reasons:

One is high-speed rail. CRTS Two types of technology employ polyurea as the waterproofing material for bridge deck waterproofing layers. Because polyurea is a two-component reactive coating, it cures extremely rapidly—often within just a few tens of seconds—making manual application impractical.

Secondly, the large-scale construction of high-speed railways has given rise to numerous waterproofing projects. For example, the waterproofing construction area of the Beijing–Shanghai High-Speed Railway exceeds 1000 Ten thousand square meters. During the same period or in the near future, there are Jing-Shi, Shi-Wu, and Shanghai. - Hangzhou, Shanghai - Nanjing, Tianjin, and Qinhuangdao. In numerous high-speed rail projects such as the Hebei–Guangzhou line, as long as a company has the construction capabilities, it need not worry about lacking work. Consequently, not only waterproofing firms but also many companies from unrelated industries have entered the sector, resulting in a flood of equipment pouring into the waterproofing market. Waterproofing industry.

In addition, the waterproofing industry focuses exclusively on high-speed rail projects and polyurea applications. It is crowded and scattered. It has not fully embraced the advanced concepts of mechanized construction. In the past, when applying waterproof coatings on construction sites, the conventional method was to mix the materials on-site and then apply them by hand or with a roller. Waterproof coating sprayers are rarely used for mechanical spraying. In today’s society, changes in efficiency translate into increased returns. Accordingly, during peak construction periods, the contractor arbitrarily streamlined construction procedures in order to accelerate progress and stay on schedule. The resulting project quality and the waiting for accidents are not uncommon. Therefore, traditional manual toothbrushing can no longer keep pace with the construction schedule.

At present, the operational performance of waterproof coating spray machines has not yet been widely adopted in construction projects. Therefore, the development and widespread adoption of waterproof coating spraying equipment are of great significance for enhancing spraying efficiency and elevating spraying standards.

The operation of the waterproof coating sprayer is simple and convenient, significantly reducing the heavy physical labor of workers in waterproofing applications during construction and boosting work efficiency. 50 % to 60 % Moreover, it is important that it allows for the efficient use of paint and reduces paint waste.
