Story highlights San Francisco started using "pee-proof" paint on its city walls

City officials hope the paint will combat the city's public urination problem

Public Works crews have painted 10 walls in the city with a special UV-coated, urine-repellent paint, according to CNN affiliate KPIX

Public Works Director Mohammed Nuru was inspired by a project in Hamburg, Germany, where walls in a night club district were coated with the liquid-repellent paint.
