Traditional methods can create secondary controls. Chemical graffiti removers may create chemical-stripper sludge, rinse residue, or solvent waste that requires characterization and disposal. Pressure washing can drive water into masonry joints. Sandblasting can erode the substrate. Permits, traffic control, and public notification depend on the method, location, material, and project.
Laser cleaning does not add abrasive media, rinse water, or chemical stripper to the work area. It avoids spent abrasive media, blast-media disposal manifests, and chemical-stripper sludge. Airborne emissions are managed with source capture and filtration. Removed coatings, captured particulate, and filters still require project-specific classification and handling, and permit requirements depend on the site and scope.
Remove spray paint from stone, brick, concrete, and metal surfaces. No ghost images on porous substrates. No chemical residue. Effective on repeated vandalism sites without cumulative substrate damage.

Remove rust, old coatings, and biological growth from water tower exteriors and interiors. Prepare for recoating on AWWA inspection cycles. No blast media contamination of water supply.
