Already treated or weathered wood must first be sanded before the coating can be applied. Otherwise the desired result might not be realised. After applying Nanoskin Wood, the wood acquires a super hydrophobic character, which can be observed when water is poured over the surface. This will result in a pearling effect of the water. Because of this hydrophobic characteristic, Nanoskin Wood offers optimal protection against water, moss and dirt. This will make it more difficult for them to adhere to the treated surface. There will also be less need for maintenance, which will save more costs. After treatment, the wood will continue to breathe and retain its natural appearance. In other words, the wood texture is preserved, the coating does not peel off and the wood will still grey. The coating is completely transparent and colourless.
