Method for treating surface of resinous softwood panel with open pores used for forming e.g. table, involves treating external surface of panel obtained by projection of sandblasting product so as to highlight grain and color of softwood

摘要

The method involves treating one out of multiple external surfaces of panel obtained by projection of granular sandblasting product e.g. corundum, so as to highlight grain and natural color of softwood. Boards of three-layered panel are removed in all resinous areas except heartwood located between a core and sapwood. The boards forming the three-layered panel are stewed before the boards are assembled by lamination so as to eliminate moisture and avoiding deformation of the boards and presence of resin and avoiding blending of the sandblasting product.
