REPAIRING GRAFFITI & VANDAL
DAMAGE TO TRAINS AND BUSES
|
Most graffiti is created using glass cutters, carbide probes or spark plugs.
It is either random swirling scratches over a large area or is concentrated
to show words (some of which are offensive), symbols or letters - football
club initials for example, or gang tags. |
Chicago Glass can supply technicians, singly or
in teams, to solve these problems in depots, either on a call-out
basis in an emergency, for day or night work, as part of a planned
glass maintenance programme or as permanent on-site staff.
| Acid graffiti is a new
phenomena to the UK, where vandals use hydrochloric acid,
mixed either with shoe polish or acetone, in a shoe cleaning
dispenser, creating a much wider band of graffiti - sometimes
coloured which is both etched into the glass and forms
a hard crust on the surface. Using a two-stage process,
the system removes, abrasively, the hard crust and polishes
out the etched surface with a minimum of distortion, leaving
a smooth, clear surface. The system has been used extensively
in the USA over the past three years where the problem
is endemic. |
