A process or method for manufacturing a fire-retardant treated wood composite board or panel, such as oriented-strand board, with a low melting point fire retardant (FR) material, such as boric acid, while the press is operating at typical press temperatures above the FR material melting point. An intervening overlay is applied to the top surface of the mat on the forming line, after the use or application of any FR material within or on the mat, prior to entry into the press. The intervening overlay covers the top surface so as to prevent the melting fire retardant material from contacting the press platen(s). After pressing, the intervening overlay may be removed from the top surface by sanding, buffing, or other methods. The intervening overlay also may be sized so as to extend over one or more edges of the underlying panel, for ease of removal post-process.
