PROBLEM TO BE SOLVED: To construct an antistatic coating floor, without leaving a pinhole in an undercoat layer, by easily finding out the pinhole in the undercoat layer.SOLUTION: A construction method of an antistatic coating floor comprises the steps of: applying a conductive undercoat layer while adjusting the inclusion ratio of a black conductive material and a pigment in the conductive undercoat layer and adjusting brightness (an L value) to 30-60 in an upper side surface of the conductive undercoat layer; and applying a conductive finish coat layer after observing a pinhole by visually observing the surface of the applied conductive undercoat layer from above and after filling up the pinhole. |
