1. An improved method of producing an engineered wood product, comprising the steps of:

forming a multi-layer strand matrix on a production line, said strand matrix comprising a top surface;

applying a pre-consolidated fines layer on the top surface of the strand matrix, said pre-consolidated fines layer comprising a plurality of fines consolidated on a paper layer prior to application of the pre-consolidated fines layer to the top surface of the strand matrix, and further comprising an upper surface with at least some of the plurality of fines opposite the strand matrix; and

consolidating and bonding the strand matrix and pre-consolidated fines layer together using heat and/or pressure.
