REKS® Praymer Antikor — anti-corrosion rebar primer with corrosion inhibitors

Rebar protection and bonding primers

During concrete repair, the steel rebar of reinforced concrete structures is coated with the one-component primer REKS® Praymer Antikor, which contains metal corrosion inhibitors. It is used when the rebar lies close to the concrete surface or the concrete contains chlorides, and to protect the steel when it cannot be covered immediately with the repair mortar. The mixed material is used within 90–120 minutes, compressive strength at 28 days is over 50 MPa, resistance to corrosive environments per GOST 31384; the primer is approved for use at domestic and drinking water supply facilities.
