The present invention is to develop a wet masking coating solution which is used to protect a shoe sole from contaminants and dust generated during a post-processing treatment of the shoe sole, such as laser etching or hot knife. The present invention proposes a water-washable masking coating solution for post-processing a shoe sole which can be perfectly removed just when the masking coating solution dried after post-processing treatment of the shoe sole is washed with water, thereby making consecutive work and mass production possible. Moreover, the present invention proposes a method for using the water-washable masking coating solution.
