HOW – Pretty simple a hydrophobic paint that repels liquids is applied to walls frequented by frequent pee’ers or late night urinators.
With normal paint the urinator’s stream hits a painted wall and runs safely down to the ground, leaving him in the clear. But with the special paint, the urine hits the wall and bounces back, ruining the goer’s shoes, if not worse.
This special paint, according to Forbes, is called Ultra-Ever Dry. The recipe that Ultra-Ever Dry uses for their patented paint is a secret, but as Forbes notes, you can find hydrophobic surfaces in nature, with some tree leaves being a great example. And, per Forbes, the paint probably works the same way:
When a water droplet hits the leaf, it simply can’t penetrate between the nano-bumps, and instead, the H2O molecules cling together forming a ball, that rolls off when the leaf is tilted. It sounds like the makers of Ultra-Ever Dry® have used a very similar idea to create their anti-pee wall coating. Their basecoat provides a layer with a specific chemical composition. When the topcoat is added, it interacts with these new molecules and, according to their FAQs, forms a geometric pattern of “high points” and lower regions, which together stop liquids – not just water – from sticking. It is incredibly good at doing this – a surface coated with this material actually becomes superhydrophobic, making it not just liquid-repellent, but self-cleaning.
