Process for producing smooth strand-based siding or structural panels using secondary pressing
11639011 · 2023-05-02 · ·

A process for producing a smooth-sided strand-based siding or wood structural panel using a secondary pressing process. The secondary pressing process is performed after the primary process completes pressing and consolidation of the substrate/board. The secondary process applies and cures the overlay after applying a water spray on the hot board immediately out of the primary process press, and before overlay application. The application of the water spray causes the surface of the board to swell and cure. A settling period follows to allow the top surface particles and strands to swell along with absorption and evaporation of the moisture. This is followed by surface sanding to remove the telegraphing and produce a smooth surface, which is then followed by lamination of the overlay(s). The process is completed by post-lamination treatment and coating of the board.
