Gives the saying piss off a whole new meaning

San Francisco city officials are implementing a new "pee-proof" paint around the city to combat the persistent problem of public urination. 

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. 

If an offender tries to urinate on a wall coated with the super hydrophobic paint, the urine, instead of running down the wall, will spray back at the person relieving himself, potentially hitting his clothes or shoes. 

Public urination has been a chronic issue in San Francisco for a long time. In 2002, the city passed legislation banning public urination and imposing a $50 to $100 fine for offenders, but the ban has had little to no impact on the problem. 

Since the beginning of January, Public Works has had about 375 requests to steam clean urine from various areas in the city. The hope is that the new "pee-proof" paint will help quell some of the city's hottest urinating zones.
