Ultra-Ever Dry Superhydrophobic and Oleophobic Coating


Spray this on your hull and see how fast you’ll go.

Ultra-Ever Dry is a superhydrophobic (water) and oleophobic  (hydrocarbons) coating that will completely repel almost any liquid.   Ultra-Ever Dry uses proprietary nanotechnology to coat an object and create a barrier of air on its surface.  This barrier repels water, oil and other liquids unlike any coating seen before.   The other breakthrough associated with Ultra-Ever Dry is the superior coating adherence and abrasion resistance allowing it to be used in all kinds of applications where durability is required.


  1. Wow! Has anyone used this as a bottom coat? How well would it work as an anti-foulant? At first glance, it looks like it would work great!

  2. It actually reduces the top speed in tests done on a 32' fishing boat. The theory is that the coating has something similar to hair that drags in the water thus creating resistance.

    • What about at sailing speeds of 12-15 kts (on the edge of ouside) or less. At what point would the drag come into play sufficiently to affect performance at these relatively low speeds? As far as the theory of a coating similar to hair, I thought that the coating was hydrophobic – meaning that it repelled water at the molecular level. I don't understand how the hair analogy would apply. Do you have more information on this?

        • Absolutely agree! I wish there was more information about this product. My idea would be to apply it over anti-fouling paint in the hopes nothing would be able to attach to the bottom. I'm probably tilting at windmills trying to get to something that would keep a bottom clean!

          • I always count on NASA tax dollars to bring us some awesome technology applied for marine use. Like those never-need-to-be-changed batteries orbiting in our satellites. So far, all we got is TANG.

  3. The first place I went was the everdry website to see what else I could find out. They do mention in their FAQ that the product is being tested as a boat bottom coat, but with no test results yet. I was hoping that someone would have more information. I guess I'll have to wait till they publish their findings.
