WOCA DRIFTWOOD lye is a unique product, which gives wood floors a weather-beaten patina. It is water-based, available in both white or grey and approved by the prestigious German Biological Building Association (IBR). By using this product, the wood will get a very nice 2-dimensional design as the driftwood lye reacts with the tannins in the wood. The product is primarily for oak wood. Finally, the surface can be treated with one of the WOCA oils to achieve a particular look.
