Brickwork and concrete surfaces are often an ideal spot for graffiti artists as they provide a blank canvas for them to work with. Removing it can be difficult, as you don’t want to risk damaging the surface, particularly on older structures. Doing so can create further problems down the line. Though it may be tempting to choose chemicals and paint thinners, this can just spread the graffiti. However, porous unpainted surfaces usually require pressure washing.

Instead, opt for a light acetone or nail varnish remover to remove the paint. If this doesn’t work, a fine steel wool gently rubbed onto the surface will remove the paint. Make sure you don’t use sandpaper, however, as it can scratch the surface.
