Concrete's dirty secret: the clean patch
Concrete is the most-tagged surface in the Lower Mainland — retaining walls, tilt-up warehouses, parkades, underpasses. It is more forgiving than brick, but it hides a trap of its own: years of accumulated grime mean that any removal also cleans the wall. Remove a tag carelessly and you trade graffiti for a glowing bright rectangle — the "ghost" — that announces where the tag used to be.
How professionals handle it
- Chemical first, pressure second — the remover breaks the paint bond so rinsing can happen at moderate pressure that doesn't scar the surface
- Hot water — dramatically more effective than cold at the same pressure, letting us use less of both
- Feathering & blending — working the edges of the cleaned area, or washing to a natural break line (a joint, a corner), so there's no sharp clean patch
- Whole-panel washing where a wall is heavily soiled — sometimes the honest fix is cleaning the full face so it's uniformly clean rather than patchy
Sealed vs. bare concrete
Bare concrete absorbs paint like brick does, which is why fast removal matters — pigment keeps migrating deeper as it cures. Sealed or coated concrete releases paint far more easily. If a wall is a repeat target, an anti-graffiti coating converts every future incident from a service call into a quick wipe-down, and on high-traffic municipal or strata assets it usually pays for itself within a few incidents.
