Indicative information only, not to be used for setting specifications.
Consistency (as applied)
Non-slump, soft paste, easily extruded with cartridge gun
Rapidly develops rubber consistency by reaction with moisture from the air
1mm depth per day
Skin Forming Time
5-10 minutes (depending on weather conditions)
