PROBLEM TO BE SOLVED: To easily and inexpensively separate masking by applying a resin solution to the unmasking part so as to integrally connect the masking of the workpiece surface and the unmasking part, and integrally separating the masking and the hardened resin solution after hardening the resin solution. SOLUTION: A resin solution 13 is applied to the whole surface or the unmasking part of a masked/sand-blasted base board 21 by screen printing, a spray and a brush. Next, the resin solution 13 is hardened by heating, drying or an exposure according to the used resin solution 13, a hardened resin 14 is formed on the whole surface or the unmasking part of the base board 21, and afterwards, the hardened resin 14 and masking 12 are integrally separated. At this time, the resin solution 13 can be integrally separated with the masking 12 since an adhesive property with the masking 12 is higher than adhesion with the base board 21 and tensile strength is high. Thus, the base board surface can be cleaned without damaging the base board. |
