  • Patent number: 5527579
    Abstract: The invention relates to a wood surface layer for a parquet and a method for manufacturing the same. A piece of fresh wood is cut in the cross-grain direction into slices or blocks which are carried through a microwave oven. Immediately downstream of the oven, as the slices or blocks are cooling, the surface thereof is coated with a water-soluble polyalcohol which impregnates in wood as a result of the action of a vacuum developing within the wood. The polyalcohol replaces some of the cell-wall water of wood and thus prevents the formation of seasoning cracks and the moisture induced movements in wood.
