Graffiti removal jet washing treats suitable markings while protecting the wall, panel or finish beneath them. Paint on sound metal behaves differently from pigment absorbed into brick or stone. Increasing pressure can damage the building fabric without removing the remaining colour, so the substrate determines the acceptable treatment.
Graffiti Removal Jet Washing
Graffiti removal jet washing treats suitable markings without assuming every shadow can be removed. Trials help protect the surface beneath.

Porous surfaces and trials
A representative test shows how the marking lifts and whether the wall, coating or joints are affected.
Building and public protection
Entrances, nearby finishes, hose routes and the active treatment area are controlled during removal.
Porous materials and removal trials
A representative trial shows how the marking releases and whether the substrate changes. Porous materials can retain a pigment shadow after the surface deposit has gone, while weak joints or coatings can limit the method. Historic or delicate fabric needs appropriate assessment before treatment, with a lower-impact method used where water jetting would risk damage.

Protecting the building and public areas
Windows, entrances and nearby finishes are protected from overspray. The active treatment area, hose route and any work at height are separated from public access. Paint fragments and cleaning residues are collected and handled according to what they contain.
Residual shadows and surface limits
The completed area is checked and any remaining mark is explained. Repainting or renewing an anti-graffiti coating is separate work unless included. A visible shadow can be absorbed pigment rather than material that can be removed safely by continuing to wash the surface.
Graffiti Removal Jet Washing: common questions
Can graffiti be pressure-washed from any wall?
No. Surface porosity, condition and paint type determine suitability.
Will the mark vanish completely?
Absorbed pigment can leave a shadow after removable paint is gone.
Does graffiti removal include repainting?
Repainting is separately agreed finishing work.
Why is a trial needed?
It checks removal and the response of the actual wall or coating.
Can a stronger jet damage brickwork?
Yes. The method must protect the retained surface and joints.
