Surface Treatment:  (1) concrete surface must be hard and close-grained, the phenomena of baring reinforcing steel bar, sand, shell and gap and rough surface must be avoid;

                 (2) the gap and hole on concrete surface must be filled and leveled up by slurry and sealer or scraped;

                 (3) when temperature is 25℃ and humidity is about 70%, the cast building by concrete can be coated no less than 4d, and the surface must be clean and no dust and slurry;

                (4) using the process of turning-over board and brushing simultaneously, the flexible part on the surface and knaggy part between the linking mould must be removed, and hole on screw board must be filled and leveled up;

                (5) mould lubricant of chemicals and emulsified oil must be used for steel mould for preventing affecting adhesion by the pollution on concrete surface;

                (6) when old tower being maintained, the surface must be no dust, lichen and unflat coating, when gunite covering and repairing, the surface must be coated after gunite covering no less than 4d.
