Repar Steel

The anticorrosive efficacy of Repar Steel is determined by the high alkalinity and by the superpozzolanic reaction of the components of the anhydrous system, as well as by the presence, in the liquid component (B), of migratory and interfacial corrosion inhibitors, capable of carrying out cathodic and anodic protection, based on organic compounds capable of making ferrous ions unavailable for feeding electrochemical corrosion processes. The polymeric components of the solution also determine further increases in the anticorrosive efficacy, especially against aggressive attacks deriving from chlorides and sulphates, and increase the adhesion between the treated bar and the concrete (adherence test according to EN 15184 in compliance with the UNI EN technical standard 1504 "Products and systems for the protection and repair of concrete structures - Part 7: Corrosion protection of reinforcements").

Carefully remove loose rust from the metal surfaces of exposed reinforcing bars by sandblasting or deep brushing until the white metal surface is obtained. This operation is essential to effectively develop the anticorrosive property of Repar Steel. Obviously, to block the advance of the carbonation profile in the concrete, it is essential to complete the restoration with the appropriate restoration mortars: thixotropic (Repar line) or pourable (Grout line).

Mix components A and B and continue mixing until a homogeneous, lump-free mixture is obtained. Apply with a brush to the surfaces of the previously prepared reinforcing bars. To prevent the application of the repair mortar from removing the still fresh Repar Steel treatment, wait for the product to harden before proceeding with the volumetric restoration. The minimum recommended waiting time is approximately 6-8 hours with summer temperatures and approximately 12-16 hours with winter temperatures. Do not apply the product with temperatures below 5°C or if it is expected that the temperature may fall below this value during the first 12 hours of curing.
