Protective coating for timber made from tree bark compounds
Coating avoids using fossil hydrocarbons so could provide a sustainable alternative to traditional solvent-based paints, varnishes and oils
In an attempt to exploit the natural protective properties of tree bark, researchers in Sweden and Latvia have created a water-resistant coating for timber using compounds from birch and spruce bark. This is the first wood-protection coating sourced entirely from tree bark, with no additional chemicals.
