Abstract

The uneven surfaces of wood-based materials such as chipboard may be improved by applying a formable coating material, smoothing and/or modelling the coating material to achieve a smoother surface, and heating the coating material to form closed pores while maintaining the smoothed surface intact. Decorative and flexible layers may also be applied to such surfaces in this manner
