Test the wall before touching the tag
Graffiti sits on brick, precast concrete, stone, metal and painted surfaces, and each one reacts differently. A method that lifts paint cleanly off steel can scar soft brick or strip the coating beside the tag. So before anything gets sprayed, our crew runs a surface test and reads how that wall responds.
That test is the difference between removing a tag and creating a second problem. It is how we avoid a pale ghost patch on a facade that took years to weather evenly.
