Apply Krystol Waterstop Treatment™ to the intended joint area with a circular, scrubbing motion for maximum adhesion and penetrations.
Attach the keyway form to the edge of the concrete form or wet-set into the plastic concrete for shotcrete applications.
Remove form from set concrete. Ensure that the keyway is clean that no wood is left in the keyway. Remove any form release agents, dirt or debris.
Tightly pack the Krystol Waterstop Grout™ mix into the keyway. Protect the application from damage by rain, rapid drying or freezing.
Note: Wait a minimum of 28 days after the concrete has been poured before packing the Krystol Waterstop Grout. Surfaces to be treated must be pre-wet to a saturated-surface-dry (SSD) condition. Do not leave any standing water.
