In a carved timber board using sandblasting according to an embodiment of the present invention, various patterns, shapes or characters, etc. are carved to be engraved or embossed on a timber board by using sand blasting to be used for various billboards, notice boards, etc. and then a hardener is applied on the timber board or the board is colored with dyes mixed with the hardener. Therefore, the hardener penetrates in the timber thereby increasing strength of the timber whereby strength of various carved patterns and shapes or characters can be increased. In addition, strength of a part in which patterns and shapes or characters are finely processed and thinly carved is increased whereby breakage and damage of the thinly carved part can be reduced so that life extension as a notice board is enabled. |
