水泥

If using humidly hardener, the surface can be humid, but there should not be any panice. b the surface should be fastness, compact and smooth, without any sand streak, floppy shell, crack, comb,bug holes. Using light blasting spray to clean the unevenness and incompact raffle, and getting the appropriate roughness, filling the crack with HF61-30 mixed with fine sand. C the surface must be clean, and have no oil stain.

如采用湿固化涂装，则表面可潮湿但不能有浮水。b水泥表面应坚固、密实、平整，不能有起砂、起壳、裂缝和蜂窝麻面等现象，可采用轻喷砂法除去水泥面上的不平整和不结实的杂物，并使其具有一定的粗糙度，对裂缝可使用HF61-30添加适量细砂填补。c表面必须清洁，须除去表面油污。
