Spray paint removal can be a challenge for the do-it-yourselfer. Depending on the job, pressure washing or sandblast equipment may be needed. Spray paint is made of pigment, a binder that holds it to the surface, and a solvent. The texture of the surface, and the amount of solvent in the paint determines how deep the paint may penetrate the masonry. As the paint dries, the solvent evaporates, and the binder solidifies. How long the paint has been on the building, and how deeply it has soaked into the masonry will determine if sandblasters are needed, or if a pressure washer will be enough for spray paint removal. If the spray paint is fresh and has been hastily applied, you may be able to handle the problem yourself. The graffiti removal process is more complicated if the paint has penetrated deeply, and you may need a professional to help deal with old, stubborn spray paint.
