Waterproofing is mostly used on roofs, underground buildings, underground parts of buildings, interior rooms that need waterproofing, and water storage structures. According to the different measures and means taken, it is divided into two categories: material waterproofing and structural waterproofing. Material waterproofing relies on building materials to block the passage of water to achieve the purpose of waterproofing or increase the ability to resist leakage, such as roll waterproofing, coating waterproofing, concrete and cement mortar rigid waterproofing, and clay and gray soil waterproofing. Structural waterproofing takes appropriate structural forms to block the passage of water to achieve the purpose of waterproofing, such as waterstops and cavity structures.

[0003] In the existing construction process, waterproof coating is applied to the parts that need waterproofing to prevent water seepage. In the process of applying waterproof coating, most of the existing methods are manually applied by holding a coating roller and then dipping it into the waterproof coating to apply the waterproof coating to the waterproof surface. This waterproof coating operation causes high labor intensity and low operation efficiency. At the same time, the waterproof layer is unevenly coated and easily wastes paint.
