  • Tips for Removing Graffiti

     

    Prompt removal by using the gentlest means of removal possible to avoid damaging the surface is usually the most effective. Test your technique on a small area to be sure it is effective and will not damage your property. You might consider hiring a professional to remove graffiti from valuable property such as signs/lighting, historical monuments, etc.

    Metal Surfaces

    • Try wiping the graffiti from the surface using any common paint thinner or penetrating oil
    • If graffiti remains, try rubbing the surface with steel wool or sandpaper
    • Next try washing the surface with a power washer
    • If graffiti still remains, paint over it

     

    Wood Surfaces

    • If the wood is not weathered and it is sealed with paint, stain or sealer, try to remove the graffiti by wiping the surface with mineral spirits.
    • If the wood is weathered or not sealed, do not use this technique as the mineral spirits will be absorbed into the wood and will drive the paint deeper into the grain.
    • Next, try washing the surface with a power washer. Again be careful to not drive the paint deeper into the wood.
    • If graffiti still remains, sand the wood and re-paint the surface.

     

    Plastic Surfaces

    • Try wiping the graffiti with a light penetrating oil. Do not use paint thinners as they can soften and discolor the plastic.
    • Next try lightly rubbing the surface with steel or bronze wool.
    • If graffiti still remains, paint over it.

     

    Glass Surfaces

    • Most graffiti can be removed from glass using a razor blade to scrape it off the surface. Use a razor blade in a holder and scrape at a 30 degree angle to the glass.
    • Next, try lightly rubbing the surface with ultra-fine bronze wool and water. Be careful not to use too much pressure as it could scratch the glass.

     

    Masonry Surfaces

    • Power washing the surface is the best method of removing graffiti from masonry and concrete. Do not exceed 700 psi and do not use too narrow a tip as you could etch the surface.
    • Sandblasting can also be used on these types of surfaces. Be sure to keep the tip moving to avoid etching the surface and to blend the colors.
    • If graffiti still remains, paint over it.
