Stop water in an instant

Stop is an extremely fast-setting and hardening cementitious mortar designed to stop localised water ingress, even under pressure, stop gushing and waterproof surfaces subject to heavy water run-off. Application is simple. Mix with approx. 25% water, stirring vigorously with a spatula until a homogeneous mixture is obtained. Wait for the paste to firm up (30 seconds to 1 minute) and then form a pad with your gloved hands. Then press the previously kneaded product firmly into the fissure or cavity and hold it for a few minutes without moving your hand until it has set, blocking the infiltration of water.
