A wet paint spray booth treating agent includes sepiolite alone or further accompanying cationic polymer or amphoteric metal compound. In a method of treating a wet paint spray booth, the sepiolite alone or further accompanying the cationic polymer or the amphoteric metal compound is added. The wet paint spray booth treating agent and a method of treating a wet paint spray booth improve the effect of reduction in tackiness and decrease the load of agents to prevent the corrosion of furnishings. The sepiolite is a fibrous mineral containing chain structures having lots of micropores so that the sepiolite can reduce the tackiness of the paint due to reaction with the particles of the paint in such a manner to adsorb the particles in the micropores thereof. Since both the particles of the paint and the particles of the sepiolite are negatively charged, when the cationic polymer or the amphoteric metal compound is added in combination with the sepiolite, the electrical repulsion is reduced so that the particles of the paint become easy to be adsorbed to improve the effect of the reduction in the tackiness.
