Cover Story: This paper explores the durability of two commercial anti-graffiti coatings for their potential use on built heritage made of concrete. The performance of a fluorinated polyurethane and a crystalline micro wax was assessed on fresh concrete slabs through natural and artificial ageing tests run in parallel with periodic episodes of graffiti removal. Samples were tested during and after 1 year of outdoor exposure on the outskirts of Oxford and up to 2000 h of artificial weathering conditions in a UVB chamber. Following colour, gloss and contact angle measurements on the coated concrete specimens, it was determined that both products weathered during exposure—the polyurethane particularly under artificial conditions and the wax under natural conditions—and therefore their ability to facilitate graffiti removal was diminished.
