It is critical to conduct test patches prior to full-scale removal. Gather Suppliesįollow safety recommendations for personal protection, including protective clothing like coveralls or a Tyvek suit, goggles, chemical-ly-resistant gloves, closed-toe shoes, or an organic vapor respirator with an N95 particulate filter.Gather tools needed for graffiti removal which may include paint brushes or rollers, nylon scrub brush- es, “scratchless” scrub pads, and razor blades to scrape excess paint from the surface. Follow the manufacturer’s recommen- dations do not use products in an “off label” or non-recommended way. Read the product literature, including any technical and safety data sheets. Review the prod- ucts or techniques being used. Documentationĭocument the vandalism before starting, keeping good photographic records. PREPARATION Carefully plan and test removal techniques before starting on a full scale cleaning. Always use the gentlest means possible to remove the graffiti. Test your treatment prior to undertaking full-scale graffiti removal. Once the graffiti is removed from a porous material, “ghosting” of the graffiti can often be seen beneath the surface.ĭifferent combinations of graffiti materials and surface materials make graffiti removal a complex issue and a demanding task. The latter is porous, and the graffiti can soak into the material. For example, a painted metal or wood surface can be more easily treated than a soft brick or stone surface. Is the surface soft? Is it powdery or “sugar- ing?” Are there signs of wood decay?ĭifferent building materials will absorb graffiti in different ways.Is the surface already painted? Can a new coat of paint be applied?.Is the feature made of unpainted wood? Metal? Stone? Brick?.Next, identify the surface material of the fea- ture that was graffitied. ![]()
