In the hot, sticky summers of many of America's cities, the smell of urine can be all too familiar.
San Francisco is peeing back at public urinators by painting its walls with UV-coated, urine-repellent paint, local TV station KPIX reports. The paint is so hydrophobic that it keeps the wall clean and sprays urine right back at offenders.
“We are piloting it to see if we can discourage people from peeing at many of our hot spots,” Public Works Director Mohammed Nuru told SFGate. “Nobody wants to smell urine. We are trying different things to try to make San Francisco smell nice and look beautiful.
I assume they make that paint out of crushed urinals.
