[0002] In the field of construction, the waterproof treatment of roof gutter is the key link to ensure the long-term waterproof performance of the building. The traditional waterproof method of roof gutter usually extends the waterproof layer of the roof to the facade or plane of the eave board outside the gutter as a whole, and is constructed by mechanical fixing. Then, a mortar protection layer or a diluted concrete protection layer is constructed on the waterproof layer to enhance the durability and mechanical damage resistance of the waterproof layer.
[0003] However, the surface of the existing waterproof coiled material is usually covered with a protective film made of plastic material. The surface of such protective film is extremely smooth, which makes it difficult for the subsequent mortar painting construction to effectively adhere. Even if forced construction, the mortar layer is prone to fall off due to insufficient adhesion, and even damages the integrity of the waterproof coiled material during the construction process, thereby causing leakage problems in the later period. Such problems not only affect the waterproof effect of the building, but also increase the cost of construction and maintenance. SUMMARY
