The best way to deal with graffiti is to prevent it. At the very least, there are certain products that will make the graffiti easy to remove. The Lithi-Tek 9500 is an excellent option to ease the removal of graffiti. Although the graffiti paint will adhere to the 9500, if you take a pressure washer to the concrete the graffiti will come right off and will make it more difficult for the offending material to bond to the wall, often even causing it to slide off the concrete.
The treatment of your concrete with the Lithi-Tek 9500 will also help to protect your concrete from extreme weathering and UV rays from the sun, helping to keep your concrete fresh and durable. When all those benefits are added to the visual benefit of helping prevent graffiti or even just to lessen the typically painstaking cleaning process the use of the Lithi-Tek 9500 on your concrete at-risk for vandalism is a no-brainer.
