Preventing graffiti on your house involves a combination of strategies. Consider installing outdoor lighting, as well-lit areas are less likely to be targeted by vandals. Security cameras can also act as a deterrent and provide useful evidence if graffiti does occur. Applying anti-graffiti coating on your exterior walls can stop paint or ink penetrating deeply making it easier to clean. Keeping your property clean, well-maintained, and free of existing graffiti sends a message that the location is monitored and less likely to tolerate vandalism.
