BUILDING BOARD AND METHOD FOR MANUFACTURING THE SAME

摘要

A building board with an appearance being three-dimensional and having a texture of processed lumber and a method for manufacturing the same are provided. A building board includes a base material board, a patterned region formed on the base material board and demarcated by a first joint-like groove and a second joint-like groove intersecting the first joint-like groove, a plurality of wood grain forming protrusions that are formed in the patterned region so as to express a wood grain pattern, an intersecting recess that is formed in the patterned region to have a strip shape extending in a direction intersecting the plurality of wood grain forming protrusions, a first coating formed on the wood grain forming protrusions, and a second coating formed on the intersecting recess, the second coating having a lower lightness than the first coating.
