The type of spray paint you use will directly affect how long it takes for the paint to dry. There is a wide range of paints available, so make sure you buy one that suits your spraying painting project. For instance, if you use epoxy or polyurethane, they tend to dry fairly quickly. However, enamel or latex spray paints can take between 8 to 15 hours to dry, which can be an issue if you need to apply more than one coat to guarantee a durable finish. Paint Krylon will be dry to touch within 30 minutes while Painter's Touch Ultra cover drys to touch within 20 minutes.
