When Paint SCENTsations is added to the paint, the result is a long-lasting air freshener that eliminates odors and refreshes rooms! Under optimum conditions Paint SCENTsations produces a pleasant scent and helps eliminate odors for up to 6-12 months in smaller areas and 4-6 months in larger areas. For best results, we recommend using two coats with Paint SCENTsations in both the primer coat and topcoat when painting. Scent 1 gallon of paint with each packet. The refreshing, light feeling of an open window on a spring day.
