The first video shows water droplets rolling off a tilted metal sheet. As you can clearly observe no trace of water is observed on the treated surface. The treated Zn sheet has become superhydrophobic and so it is fully protected against the corrosion caused by water.The Zn sheet is placed outside. The treated surface is left outside to test whether the coating will remain superhydrophobic after being exposed to sun, wind, rain, snow and atmospheric pollutants.

The second video shows the same coating applied this time on a wall. The coating was applied on the wall again by brush, about a year before the video was captured.

The upper part of the picture shows the untreated wall. The untreated wall is fully wetted. The rest of the wall which was protected with the coating is superhydrophobic. Consequently the wall is protected against water.

The same coating has been applied on various substrates like stones, concrete, glass, wood, fabric and the results were excellent. Every substrate became superhydrophobic!
