Hard to tell not being there and seeing for ourselves. If the paint is a quality type and applied properly, probably not, but if there is any issue with how it was applied, maybe it could. However, use a lower pressure nozzle fitting and work from a little further back until YOU see how things go. If YOU fell it is okay to get more aggressive, then YOU have to make that decision. But go slow and use a lower pressure nozzle and work from a further distance and see what happens... JMHO!
