Waterweld is a unique putty that permanently seals any hole, gouge or crack under water or while still leaking. When applied, this putty “mushrooms” through and around holes, grabbing the edges and setting hard as steel in 20 min. Simply cut off as much material as you need, twist and knead with your fingers and apply. Putty stays pliable for about two min. after mixing and sets in just 20 min. Full cure only takes a few hr. Waterweld creates a super-strong repair that is waterproof plus petroleum, chemical, acid, vibration and temperature resistant. Like metal, repairs can be drilled, ground, tapped, machined, filled, sanded or painted when cured. Withstands temperatures up to 300°F. Ideal for repairing water lines, battery cases, pipe joints, buckets, stock tanks, drains and more. Approved by the National Sanitation Foundation for use with potable water. 2-oz., 7" stick. USA made.
