Pre-set CC Properties
Setting
Working time: 1-2 hours subject to ambient temperature.
CC will achieve 70-80% strength at 24 hours after hydration.

Method of hydration
Spray the fiber surface with water until it it feels wet to touch for several minutes
after spraying.

Re-spray the CC again after 1 hour if:
1.installing CC in a steep or vertical surface;
2.Installing in warm climates;

Notes:
1.CMC can not be over hydrated and an excess of water is always recommended;
2.Minimum ratio of water:CMC by weight: 1:4
3.Don't jet high pressure water directly onto the CMC as this may wash a channel in CMC.
4.Please use non-saline water for hydration.If CMC will be used for sea projects,please
advise us beforehand.
5.CMC can hydrate and set under water;
6.CMC has a working time of 1-6hours after hydration. Don't move or touch CMC
once it has begun to set.
7.Working time will be reduced in hot climate;
8.CMC will set hard in 2-3 hours,but will continue to gain strength for several months.
