WATERPLUG is ready-mixed, highly accelerated underwater cement, scientifically designed for quick repair work of concrete subject to hydrostatic pressure, active leaks or underwater conditions.
WATERPLUG sets quickly while bonding to the surface and expanding to rapidly block the flow of water in a few minutes after application. Use as a permanent patching material above or below grade.
WATERPLUG’s super-fast setting, non-shrink and high-bonding properties make it an excellent mortar for anchoring ornamental iron, bolts, posts and dowels. WATERPLUG expands slightly to grip the surface of the embedded item and fill every crevice of the concrete cavity.

APPLICATIONS
Apply immediately after mixing. As soon as WATERPLUG has achieved a dry, putty texture and a compatible shape, force the material into the crack or cavity compressing it firmly using a gloved palm, trowel, wood block or other flat object. Hold it in place for over a minute. If there is a strong water flow hold for six minutes. Do not brush or trowel over surface. Shave off excess material with a knife or other similar sharp tool. For long, leaking vertical cracks, patch with successive small amounts of WATERPLUG starting at the top of the crack.
For anchoring bolts, posts, dowels, etc., drill a hole deep enough to allow 1/2 in (13 mm) around fixture, mix to a putty consistency and fill hole. Then tap object firmly into place. Keep damp for 15 minutes. Do not apply excessive pressure for several hours.
