METHOD OF WORKING A WORK PIECE WITH A COATING OF A LIGNIN-DERIVED SUBSTANCE, WOODEN ELEMENT WITH A COATING OF SUCH LIGNIN-DERIVED SUBSTANCE, AND STRUCTURES, INTERIOR OR EXTERIOR, WITH SUCH WOODEN ELEMENT

摘要

The invention relates to a method of working the surface of an edge or pattern on a work piece made, at least partly, of a wooden material. The method comprising a primary production step of processing the work piece by shaping said edge or pattern on the work piece. The primary production step further comprises applying a coating of phenylpropanoid polymer to said shaped edge or pattern, said coating being a surplus to any phenylpropanoid polymer present in the wooden material before applying the coating, and heating and mechanically working said edge or pattern, resulting in respectively the coating of phenylpropanoid polymer hardening during polymerization and a finished surface of said edge or pattern on the work piece.
