Graffiti and paint splatter: what pressure washing can and can't do

Not every stain is a pressure-washing job. Here's the honest breakdown for the two most common calls.

• On porous concrete: yes, high pressure + graffiti remover works, but leaves a "clean square" that stands out
• On brick: partial success; often leaves a shadow
• On painted surfaces: no — the graffiti and the underlying paint both come off. Repaint is the only clean fix.

Usually beyond pressure washing alone. Chemical strippers become necessary. Referral to a specialist is often cheaper than trying and failing.

• Latex (water-based): pressure + a scraper often works if caught within a week
• Oil-based: usually requires a solvent-based paint stripper first
• Old dried paint: needle scaler or grinder territory

Almost never a pressure-wash job. High enough pressure to lift paint will damage the wood beneath. Sanding is usually the answer.

If you send me a photo, I can usually tell in one glance if pressure washing will work. If it won't, I'll tell you before you book — and often recommend the right specialist. No point taking your money for a job I can't complete.
