Method library
Every graffiti removal method, side by side.
Ten professional methods rated for cost, effectiveness, speed, and surface safety.
Pressure Washing Graffiti Removal
Pressure washing uses high-pressure water jets (2,500–3,500 PSI for spray paint) to blast graffiti paint off hard outdoor surfaces. It's the most common and cost-effective removal method across Canada, accounting for roughly 40% of all professional graffiti removal jobs according to industry estimates.
Chemical Graffiti Removal
Chemical removal uses specialized solvent formulations to dissolve graffiti paint at the molecular level. A trained technician selects from dozens of chemical families — alkaline strippers for latex-based paints, solvent-based removers for enamels and spray paints, and bio-based gel formulations for environmentally sensitive areas.
Sandblasting Graffiti Removal
Sandblasting (also called abrasive blasting or media blasting) uses compressed air to propel fine abrasive particles — silica sand, garnet, walnut shell, glass bead, or baking soda — at high velocity against graffiti-covered surfaces. The impact physically strips paint from the substrate, making it the most powerful mechanical removal method available.
Paint Over Graffiti Removal
Paint over (also called graffiti cover-up or colour matching) applies opaque paint over graffiti to completely conceal it. Unlike removal methods that strip the graffiti paint, paint over adds a new layer on top — making it the fastest and cheapest option but not a true removal.
Laser Graffiti Removal
Laser graffiti removal uses focused light energy (typically Nd:YAG lasers at 1,064 nm wavelength) to vaporize paint molecules without physically touching or chemically altering the underlying surface. The laser pulse heats the paint layer to its ablation point — the paint converts directly from solid to gas in nanoseconds, leaving the substrate completely undamaged.
Anti-Graffiti Coatings
Anti-graffiti coatings are transparent protective barriers applied to surfaces before graffiti occurs. They create a non-stick layer that prevents spray paint, marker, and adhesives from bonding to the substrate — allowing future graffiti to be removed in minutes with hot water and a pressure washer rather than chemicals or sandblasting.
Emergency Graffiti Removal
Emergency graffiti removal is a rapid-response service where certified contractors arrive within 24–48 hours of a graffiti report to remove vandalism before municipal bylaw deadlines expire. This service exists because Canadian cities impose fines of $1,000–$5,000 on property owners who fail to remove graffiti within prescribed timeframes.
Recurring Graffiti Management
Recurring graffiti management is a subscription-based service where contractors provide ongoing removal, prevention, and monitoring under a fixed-price contract. Instead of calling for individual emergency removals at $5–$15/sqft, property managers pay a predictable monthly or annual fee that covers unlimited removals plus preventive coatings.
Heritage Building Graffiti Removal
Heritage building graffiti removal is a specialized service for removing vandalism from historically significant structures without damaging original materials. In Canada, heritage buildings are protected under federal, provincial, and municipal designation systems — and improper removal methods can result in fines, criminal charges, and loss of heritage designation.
Graffiti Prevention Systems
Graffiti prevention is a multi-layered approach that combines physical barriers, surveillance technology, environmental design, and community engagement to deter vandals before graffiti occurs. Unlike reactive removal services, prevention targets the root cause — making surfaces unattractive, inaccessible, or risky for vandals.
