This is a 3 pound jar of E-Z Patch 7 F.S., Gray Rebar Rust Repair, which is a successful fast set mixture that seals rebar rust problems without having to cut out the rebar. This is an exceptional cement mixture that contains special acrylic modified materials with pozzolans (siliceous volcanic ash) and polymers.
E-Z Patch 7 is designed for both underwater and fast set above water (with water lowered) repairs. Use cold water to slow set and warm water for faster set. Allow to set overnight before swimming.
