San Francisco painted nine walls in the Golden Triangle with Ultra-Ever Dry, a superhydrophobic paint coating that repels liquid. The aim of the city experiment is to discourage men, usually drunk, from urinating on the walls of the Mission, Tenderloin and SoMa communities.

The pilot project follows what the German city of Hamburg did in the early part of 2015 in a bid to stop beer drinkers from splashing their pee on the street while on their way home from a drinking session, reports Citylab.

San Francisco passed a law in 2002 to prohibit public urination with a fine ranging from $50 to $500, but because peeing in public often happens at late night when there a few cops patrolling the area, men with kidneys filled with alcohol get away with the act. To solve the problem, which had resulted in 375 requests for the city to steam clean the urine, more public toilets were built under the Public Work Department’s Pit Stop programme, according to the San Francisco Chronicle.

The walls painted with the pee-repelling paint have streak designs and signs reminding the public that the area is not a public restroom and for the reader to hold their urine while seeking an appropriate place to release their kidney’s contents. But it did not state the wall would bounce back their pee and wet them if they insisted on urinating.

The paint, according to Spillcontainment, is made of water and hydrocarbons coating that would repel most water-based and some oil-based liquids. That includes urine which are repelled by the peaks or high points in the patterns of geometric shapes painted on the wall.

It has anti-wetting, anti-corrosion, anti-icing, anti-contamination, self-cleaning and product life-extending properties, according to the Web site of the paint manufacturer in Florida. Its anti-contamination property protects surface painted from liquids that contain bacteria and radiation.

Car owners could use the paint on the vehicle’s windings, nuts and bolts to prevent corrosion, but they should not use it on the windshield because it would obscure visibility.
