It vibrates by pouring layer, vibrating head sinks to it in concrete naturally perpendicular to concrete surface；The front end of vibrating head should insert
Enter a preceding pouring layer, insertion depth is no less than 50mm；
C carries out plastering processing before the initial set of FS102 water-proof concrete, final set respectively；
Finish brushing: d after facing is cleaned out, carries out finish brushing or spraying to facing.Such as use spraying should incite somebody to action
Spray pressure is controlled in 0.3-0.4Mpa, it is desirable that finish brushing will uniformly, and thickness is consistent, must not leak brush；
E, maintenance, wall, the column of FS102 water-proof concrete construction preferably use curing in the mold, and curing time should not be less than 3 days,
Continue watering, covering curing after curing in the mold, curing time should not be less than 14 days；
Step 6, the construction of FS101 waterproof mortar external wall elevation
A, it is after the completion of concrete construction, outer plinth course wire brushing is clean, and before smearing waterproof mortar with water into
Row rinses；
B carries out hair pulling treatment using the cement mortar mixed with building adhesive, after it reaches some strength, with mixed with FS101
Plain-water slurry be combined processing on surface, then spread the 20mm thickness FS101 waterproof mortar prepared, smeared with trowel flatten it is close
It is real；
C, yin-yang angular position are made into fillet, and external corner arc diameter 20mm, inner corner trim arc diameter 50mm are smeared two times after plain-water slurry processing
FS101 waterproof mortar and press polish compacting；
