repair crack or hole in pipe

Step 1: Clean surface, removing any dirt or debris.

Step 2: Put on gloves. Cut or break off desired amount of WaterWeld, replacing unused portion back into tube for future use. Knead WaterWeld with your fingers until it becomes a uniform color, and apply along the line of the crack. You can also use WaterWeld to plug any larger holes.

Step 3: Allow WaterWeld to fully dry and cure, about an hour. WaterWeld will cure to white, and will be waterproof upon drying and curing.
