Generally when applied the surface to be treated will remain as it is but its colour will deepen slightly plus the gloss levels will be slightly reduced.
To removed Graffiti from the surface which has a sacrificial coating on it, either hot steaming on porous surfaces or an Anti Graffiti removing agent/gel on non porous surfaces.  After removal the Sacrificial Anti Graffiti coating will have to be re applied.
This is why it is call sacrificial because during the cleaning process the coating Sacrifices itself to remove the Graffiti on it.
