Graffiti and Vandalism Removal Services in San Antonio, Texas
Brick & Mortar
For brick & mortar surfaces, it is recommended to use a pressure level between 2,000 to 3,000 PSI, keeping a 25-degree nozzle tip approximately 2 feet from the surface. Older brick surfaces will require a soft washing technique. Begin washing from the top, moving down and adjusting the pressure level as the graffiti starts to wear down.
Wood
For painted or stained wood, it is suggested to use mineral spirits, a pressure level of 3,000 PSI, and a 25-degree nozzle tip to remove graffiti. This method may not be as forgiving on older wood, though, so it is recommended to paint over the graffiti instead.
Metal
For metal surfaces, the help of a paint thinner or industrial chemical graffiti remover is required. Then, pressure wash the surface using a recommended pressure level between 2,000 to 3,000 PSI to thoroughly remove any remnants.
