A method of manufacturing a finished product from a lignocellulosic material such as a length of wood or chipboard, consists of impregnating the lignocellulosic material with an impregnating composition containing a thermosetting resin in a solvent, a styrene polymer in a solvent, optionally an anhydride in the solvent, optionally a mineral oil or a vegetable oil in a solvent, optionally a catalyst for the thermosetting resin, and optionally a hydrophobic agent. Thereafter, there is removed from the impregnated lignocellulosic material any excess of the impregnating composition and then there is removed the non-aqueous solvent or solvents. The product is then subjected to suitable conditions of temperature and pressure to polymerise the thermosetting resin to form the finished product.
