Anti-graffiti sprays are protective coatings applied to surfaces to prevent graffiti paint from adhering. These sprays create a barrier that makes it easier to clean off unwanted markings without damaging the underlying material. They are commonly used on walls, public buildings, and other structures prone to vandalism. There are two main types of anti-graffiti sprays: sacrificial and non-sacrificial. Sacrificial sprays form a temporary layer that can be removed along with the graffiti, while non-sacrificial sprays allow for repeated cleaning without needing to reapply the coating. Both types help maintain the appearance of surfaces and reduce cleanup costs.
