A rapid setting, watertight barrier suitable for use with clean fresh water. It cures in less than 2 minutes and can be used to seal joints prior to overcoating with Bond It Tanking Slurry. This product effectively seals and fills cracks and joints, plugs running water leaks, and can be used to anchor fixings. To use, cut out holes or cracks to a square (not a V) shape. Mix with water into a putty by hand. Then, with a gloved hand or trowel, plug the mixture into the hole or crack and press hard until the plug has set. Trim flush if required after water has stopped running.
