This study addresses the challenge of protecting building façades by evaluating lime-based coating mortars treated with thirteen surface finishes, including silicate paints and commercial hydrophobic, oleophobic, and photocatalytic products. The goal was to identify the most effective surface protection solutions by assessing multiple performance aspects, particularly self-cleaning and anti-graffiti capabilities. A straightforward assessment framework was established, focusing on key surface properties to support decision-making. Initial evaluations included measurements of gloss, chromatic coordinates, static water contact angle, and roughness. Subsequently, specimens were stained with methylene blue and exposed to ultraviolet light for 145 h to evaluate self-cleaning performance via color change monitoring. A graffiti removal was then conducted, using silver spray paint and steam cleaning, with the cleaning efficiency assessed using an established scale. At 60°, gloss was highest for the anti-graffiti coating, though all values were generally low. Overall, color compatibility was preserved. Hydrophobic behavior was observed in silicate and hydrophobic treatments, while most photocatalytic coatings showed hydrophilic properties. The lime-based photocatalytic paint demonstrated the best self-cleaning performance, and, as expected, anti-graffiti coatings were most effective in graffiti removal. Some non-photocatalytic coatings also led to color changes under light, and one photocatalytic treatment provided partial resistance to graffiti. The findings underscore the need for additional research on rain exposure and long-term durability. At this stage, selecting a suitable coating depends on environmental exposure and anticipated degradation agents.
