How do manufacturers test for resistance to graffiti and other forms of vandalism?

Manufacturers employ rigorous testing methods to evaluate how well materials resist graffiti and other forms of vandalism. Common techniques include chemical exposure tests, where surfaces are subjected to solvents, paints, and markers to assess cleanability. Abrasion tests simulate scrubbing or pressure washing to determine if coatings degrade. UV aging tests examine long-term durability under sunlight. Some labs also conduct adhesion tests to measure how easily graffiti can be peeled or scraped off. High-performance anti-graffiti coatings often undergo accelerated weathering to mimic years of wear. These standardized tests help ensure public infrastructure, transportation, and architectural materials remain resilient against vandalism.
