The proposed investigation aims to identify resources for recommendable coating choices to prevent undesirable alteration or even destruction of compromised weathering steel pieces. This research will explore the current state of the literature on recommended anti-graffiti coatings choices and cleaning treatments (which may not cause any visual impact and possible interference with patina development) of Corten-weathering steel. An ideal conservation coating provides sufficient protection to treated substrates, preserves the natural color, gloss, texture, and integrity of weathering steel substrates and adequately aids in the complete and safe removal of graffiti, without altering the appearance of the patina layer.
