Repar Monosteel
The anti-corrosive effectiveness of Repar Monosteel results from the high alkalinity and from the superpozzolanic reactivity of components. The specific corrosion inhibitor contained in the compound (DCI - Corrosion Inhibitor Agrèment Certificate BBA** n.96/3232), conforming to the standard UNI 9747, is based on a reaction which is capable of making unavailable the ferrous ions for the supply of the electrochemical processes of corrosion. The polymeric components of Repar Monosteel also determine further increases in the effectiveness against corrosion, especially vis-à-vis the aggressive attacks arising from chlorides and sulphates. (BBA = British Board of Agrèment).
Fields of application
Passivating protection treatments of the reinforcement rods in interventions of restoration of works and articles in reinforced concrete, in marine, mountain and industrial environments.
Allowed supports
Concrete
Rusty reinforcement rods
Preparation of supports
Carefully remove non-adhering rust, present on the metal surfaces of the exposed reinforcement rods by blasting or deep brushing , until the following condition is reached: "almost white metal" (metal colour as if it has just come out of extrusion).
Mode of use
Pour about half a litre of water into a bucket, add Repar Monosteel and additional water necessary for achieving a fluid, dense, brushable consistency. Continue mixing until a homogeneous lump-free mixture is obtained. Apply by brush on the surfaces of the previously prepared reinforcement rods.
