Graffiti and Spray Paint Contamination

Graffiti paint acts as a deliberate contaminant that spray artists apply to urban surfaces, where it quickly bonds through chemical adhesion and solvent penetration. Unlike everyday dirt or pollutants, it sets up deep into porous substrates while creating slick, resistant films on non-porous ones, turning removal into a significant challenge that often leaves behind stubborn stains. Laser cleaning tackles this effectively by vaporizing the paint layer precisely without damaging the base material, achieving a clean finish that traditional solvents struggle to match.
