There are many great examples of Graffiti artwork around Christchurch, but unfortunately most graffiti scrawled across our buildings is unsolicited and unattractive.
The best solution for dealing with Graffiti is to remove it ideally within 24 hours. A quick response will deter further attacks whilst leaving graffiti unaddressed will simply attract more.
There are several methods for removing Graffiti which involve either removal or painting over the graffiti and will depend upon the surface that has been affected.
Water blasting is effective on smooth unpainted surfaces whilst porous surfaces such as rough sawn timber, brick and stonework are tricky, often leaving behind a ‘graffiti ghost’.
Solvent based graffiti cleaners can be used to remove graffiti from painted surfaces, but always test the graffiti cleaner on a painted area out of sight first. It may remove the original coating as well as the graffiti.
Painting over graffiti is another option, for the best results seal the graffiti with an oil based primer first. This will stop the graffiti paint bleeding through the top coat avoiding the ugly ‘Graffiti Ghost’. Ensure the original paint colour is used to repaint the affected area. If the original paint is not available consider repainting the whole area. A patch work of mismatched colours is nearly as unsightly as graffiti.
For long term solutions consider an anti-graffiti coating, such as the Mainland Anti-Graffiti Coating. Invisible to the eye, an anti-graffiti coating will form a clear protective barrier over the original paint surface. A solvent based cleaner can be used to remove the graffiti without affecting the original paint coating. The Mainland Anti-Graffiti coating will withstand multiple cleans before needing to be re-coated. Additionally, if a change of the original paint colour is desired the Mainland Anti-Graffiti can be over coated with acrylic paint.
