Heritage brick graffiti, no surface damage
- Surface
- Sandstock heritage brick wall, ~6m²
- Problem
- Spray-paint tag on porous heritage brick — aggressive cleaning would have eroded the brick face

Spray paint on heritage brick — removed without damaging the surface. Sandstock is porous, so any aggressive method would erode the face and mortar joints. Used a targeted chemical solution to break the paint at the molecular level, then a controlled-pressure rinse at the right angle to flush residue. Sealant and mortar joints came out untouched.
