Murals are graffiti's strange exception
Commissioned murals are one of the better-documented graffiti deterrents — most taggers respect artwork, and a painted wall offers no blank canvas. Cities across BC fund mural programs partly for this reason. But "most" isn't "all," and when a mural does get tagged, the stakes are brutal: use normal removal chemistry and you take the artwork off with the tag.
Protect it before it's hit
The professional standard is a clear, sacrificial anti-graffiti coating applied over the finished artwork (with the artist's blessing — good practice and often contractually required). The coating is invisible, breathable, and made to be removed: if the mural is tagged, the coating comes off carrying the tag with it, the artwork underneath is untouched, and a fresh coat goes on. Without that layer, removing graffiti from a mural is delicate, expensive restoration work — sometimes only the muralist can truly fix it.
If an unprotected mural has been tagged
- Don't let anyone "just try" a solvent — the mural's own paint is as vulnerable as the tag
- Photograph and act fast — the longer the tag cures, the narrower the safe-removal window
- Use conservation-grade methods — spot-tested, gentlest-first, often removing the tag layer mechanically or with mild chemistry a millimetre at a time — this is exactly our sensitive-surface specialty
For BIAs and property owners commissioning new murals: budget the coating into the project — it's a small fraction of the artwork's cost and the only insurance policy that actually works. We coat new murals and maintain protected ones across the Lower Mainland.
