1-minute, rapid setting hydraulic cement

CLADSTOP 1 is designed for structural patching and for use as a leak stopper and water plug.  As a rapid-set, hydraulic cement compound, it can instantly stop running water and/or seepage through concrete or masonry walls and floors.

Designed for an ultra-quick reaction, CLADSTOP 1 sets in 60 to 90 seconds depending on the temperature of the mixing water, the surface onto which it is applied, and the mass. Low temperatures will decrease the set-time, while higher temperature accelerate the set-time.
