| 摘 要： | 聚脲防水层施工是一项新技术,防水层施工控制的重点及难点为基层处理、底层喷涂及聚脲防水层施工。基层质量的好坏是决定喷涂聚脲防水工程质量的关键,喷涂材料应尽量选择与基层及聚脲涂层粘结力强、对混凝土基层渗透率高、封闭性能好、固化时间短的材料,可为类似工程提供借鉴。

| Abstract: | Polyurea waterproofer construction is treatment, bottom spraying and polyurea waterproofer a new technique and its main difficulties include construction. Substrate condition is the key point substrate affecting the polyurea waterproofer spraying quality, so the spraying material shall better use those which have strong cohesive force with the substrate and polyurea coating, high penetration ratio on concrete substrate, favorable sealing performance and short curing time.
