After installation, the surface of the coating is dried (30 minutes in summer, 1 hour in winter), the Odor disappears in 2 to 3 hours with the window fully open. If the window cannot be opened or closed, it may remain until the next day. For this reason, if you are worried about the Odor after application, deodorize with negative ion or ozone generator.
Since it is solvent-based, there is a smell of nail polish remover. The Odor disappears over time. However, for several hours after the application until the surface is dried, ventilation is not possible, so the smell fills the room in the case of small narrow space.
