Removing graffiti
You do not have to accept that once your property has been subject to graffiti it is there to stay. One of the most effective strategies against illegal graffiti is to remove it as quickly as possible and to persist in removing it.
Graffiti can be removed
Graffiti is always more easily removed if done as soon as possible after occurrence and before the paint has fully dried.
There are three key steps for effective removal:
- Identify the surface type and substance to be removed.
- Select a removal method
- Apply preventative measures
Removal Methods
Paint-out
Paint is used to cover over graffiti on smooth, painted surfaces. It is fairly low cost, easy to apply and paint is a relatively safe product compared to removing graffiti with some chemical solvents. When painting out graffiti be ware of the folowing issues:
- Avoid a patchwork effect buy either correctly matching the old and new paint, or repainting the entire surface.
- Prepare the surface well to reduce “bleed – through” of the graffiti and to ensure a long lasting and attractive result.
- Ensure that the process is safe and environmentally friendly, including clean up of brushes and disposal of paint.
Chemical Removers
Chemical removers vary, but typically the stronger the solvent, the faster it will dissolve or remove paint. In some cases, stronger solvents may require more safety consideration or personal protection. A solvent or cleaner that is poorly matched to a particular construction material, however, may create aesthetically unappealing results. Successful product selection is critical. When using any chemical remover, keep in mind who will be using the product, the safety precautions to follow, and any training required for the product user. Secure a material safety data sheet (MSDS) from the distributor of any hazardous chemical. The MSDS will show chemical make-up and any health and safety risks associated with use.
Pressure Washing
Pressure washing equipment uses water or water in combination with a solvent to remove graffiti from a surface. A solvent may first be applied and then the surface is washed with pressurized water. Sometimes a blasting media, such as baking soda or sand, is used to remove graffiti. While pressure washing is effective, it can wear down the surface being treated.
