It can also be used to saturate oil free oakum, or open cell backer rod to seal expansion/control joints. When there is a particularly heavy water flow, or at lower temperatures when it becomes desirable to speed up the reaction time to more effectively cut off the flow, we do have an accelerator (not an activator) called AquaLASTIC-ACT available.  It will reduce the reaction time by approx 50%.
