As John-David stated, durable anti-graffiti coatings live in the IM category. IM has performance requirements such as chemical resistance and surviving repeated scrubbing or abrasion - both typical for non-sacrificial anti-graffiti coatings. Some manufacturers bend the curve a bit by selling multiple layer systems where each layer is sacrificial, but still call the product an IM coating. Sacrificial coatings designed to be removed by pressure washing or stripping materials and replaced after each tag would not typically be classified as IM coatings. These would live under other categories such as Low Solids if it is less than 1-pound per gallon solids content or Waterproofing Concrete/Masonry Sealer if marketed for use on brick, block or stone and it has additional water repellent characteristics.
