Cleaning of graffiti can cost a community millions of dollars annually. Across the globe companies are attempting to develop surface coatings to prevent vandals from being able to deface public property. Depending on the substrate and the severity of the graffiti problem different protective coatings have different benefits and advantages. Portolesi Structural can apply sacrificial coatings to form a clear barrier over a surface for protection, semi-sacrificial coatings to act as a penetrating sealer to protect the surface pores or even permanent coatings. Permanent coatings create a protective surface that spray paint cannot bond to, whereby a simple solvent may be required to remove graffiti. Portolesi Structural are accredited with the CSIRO under the Painting Contractor Certification Program (PCCP).
