Anti-graffiti coatings fall broadly into two families. Sacrificial systems are removed along with the paint each time they are cleaned, while permanent systems stay in place and let solvents lift the graffiti off a non-stick surface repeatedly.
A sacrificial wax or polymer layer is stripped off with the graffiti during cleaning, taking the paint with it, and then reapplied afterwards. It is a lower upfront cost but needs reapplying every time, which adds up on frequently targeted walls.
Permanent anti-graffiti coatings create a durable non-porous surface that solvents can clean without stripping the coating itself, so there is no need to reapply after every incident, though the initial system costs more to install correctly.
For a wall targeted rarely, a sacrificial coating kept in stock for occasional touch-ups can be perfectly practical. For a location targeted repeatedly, the labour saved by not reapplying a permanent system after each clean usually justifies the higher initial spend.
It depends on how often the wall is targeted. Sacrificial coatings cost less initially but need reapplying after cleaning, so frequent incidents favour a permanent system instead.
Both can be formulated for porous substrates, though the correct primer and coating type differ from what would be used on smooth render or metal.
No — it only affects how easily it can be removed afterwards. It is a cleaning strategy, not a deterrent on its own.
Tell us how often the wall gets targeted and we will recommend sacrificial or permanent coating.
Sacrificial and permanent anti-graffiti coatings solve the same problem differently, and the right one depends on how often the wall is hit.
