At 4 Corners we now offer an optional "Anti-Graffiti" coating for all flat finish signs.
This is a self adhesive Polyester Laminate, which is applied to the finished surface, to give a hard wearing finish. If someone writes over the surface with a permanent marker or even spray paint, all it takes is a cloth with a small amount of Cellulose Thinners and the offending Graffiti is easily removed.
Depending on the finish quality, the Anti-Graffiti film can also be applied to existing Flat Finish signs.
Have a look at the video below, to see the Anti-Graffiti in action.
