Removing graffiti within 24–48 hours makes it easier to clean, reduces the recognition for graffiti vandals from having their graffiti on display, and discourages more graffiti.
Make the target harder
- Reduce access to walls (eg fencing, landscaping).
- Restrict access during high-risk times (eg lock gates at night).
- Increase lighting.
- Increase surveillance (eg install CCTV, use alarms or movement-activated lighting).
- Use materials and coatings to deter graffiti.
- Reduce the size and number of walls through landscaping, colour, texture, art or design.
- Use the principles of Crime Prevention through Environmental Design (CPTED) to reduce the opportunity for offenders to target your property.
Reduce the rewards
- Remove graffiti quickly.
- Remove the most prolific and prominent tags first.
- Don't show images of graffiti in the media.
- Use anti-graffiti coatings.
There are two types of protective anti-graffiti coatings:
- sacrificial coatings are protective but come off when graffiti is removed; so must be reapplied
- non-sacrificial or permanent anti-graffiti coatings are unaffected by the graffiti-removal process, but they are more hazardous and difficult to apply.
