Corrosion, which is a deterioration of materials caused by the chemical reaction with their environment is unavoidable when using metal as a construction material. Based on the mechanisms of the corrosion process, the corrosion can be chemical or electrochemical depending on the medium in which it occurred. The protection of materials against corrosion, depends on the material’s surroundings. Corrosion resistance of the most important structural metal, steel (alloys of iron and carbon), can be achieved by additional alloying with appropriate alloying elements. Metal protection technologies include various other methods of corrosion protection, such as coating protection. Prior to this procedure, it is important to prepare the metal surface well, which can be carried out by various procedures. Water blasting is an example of an environmentally friendly way of preparing a metal surface. Due to increasingly stringent environmental requirements and norms accompanied by legislation, environmentally friendly solutions are being sought in the remaining phases of the process. Therefore, the most frequently used environmentally friendly coating is water-based coating. The waste that is generated through the process of corrosion protection has to be disposed of in a safe and environmentally friendly way.
