A method for forming a thin coating film by using carbon dioxide gas is provided to improve the peel or lifting resistance, waterproofing property and adhesion of a waterproof coating layer, particularly in a floor or wall of a swimming pool or bathroom. A method for forming a thin coating film by using carbon dioxide gas comprises a step of spraying carbon dioxide gas onto a coating film formed by a silicate-containing paint at room temperature within 4 hours before the coating film is dried. The carbon dioxide gas is selected from gas filled in a gas container or dry ice. The silicate is at least one or more selected from sodium silicate, potassium silicate, lithium silicate and aluminum sodium silicate, and is added in an amount of 1-10 wt% based on the total weight of the paint.
