Yes—there are special coatings designed exactly for this, and they work by making the bench surface either too slick or too sacrificial for spray paint to grab onto. The best choice depends on the bench material and how often you can do maintenance.
Anti-graffiti coatings generally fall into two groups. Sacrificial coatings are clear waxes, silicone films, or thin polymer barriers that sit on top of the bench. When graffiti is sprayed, you don’t clean the paint off the coating itself; you wash or wipe the coating away with hot water or a mild cleaner, and the paint comes with it. After that, you simply reapply the coating to that spot. These are cheap and easy to apply, which makes them good for benches that get hit occasionally, but they do require recoating after every incident.
Permanent anti-graffiti coatings are tougher. These are usually two-component polyurethane, epoxy, siloxane, or fluoropolymer clear coats that create a hard, non-porous, low-energy surface. Spray paint struggles to bond to that surface, so most graffiti can be removed with a mild solvent or pressure washing without ruining the finish. For wooden park benches, a penetrating siloxane-based sealer or a clear exterior polyurethane works well. For metal benches, powder coating plus a clear anti-graffiti topcoat is a solid combination. For recycled plastic or composite benches, ask if the manufacturer offers a factory-applied anti-graffiti clear coat.
Surface preparation is just as important as the coating. The bench needs to be clean, dry, and free of peeling paint, oil, sap, or bird droppings before you apply anything. Follow the product’s recoat and curing instructions carefully—most coatings need several days to fully harden before they develop their non-stick properties.
One honest note: no coating makes graffiti bounce off completely. The goal is to stop the paint from biting into the surface so cleanup is fast and inexpensive. If you manage a public park, pair the coating with quick removal. Graffiti attracts more graffiti, so removing tags within 24–48 hours is one of the strongest deterrents you have.
Look for terms like “anti-graffiti clear coat,” “sacrificial graffiti barrier,” “graffiti protection system,” or “permanent anti-graffiti coating.” Always test a small hidden area first, because some clear coats can slightly darken or change the gloss of the bench.
For most park benches, the best practical setup is a sealed, well-prepared surface plus a clear anti-graffiti topcoat—and a small cleanup kit nearby.
