The best type of paint for vinyl shutters is Krylon Fusion by Sherwin Williams because it is an exterior plastic spray paint that adheres well to vinyl and hard plastic surfaces, according to ExteriorSolutions.com. This type of paint works best on shutters made of polypropylene, which normal paint does not adhere to well, because it bonds exclusively to hard, rigid and non-flexing surfaces.
Some shutters purchased from the store come ready to paint and are made with a material called polystyrene. To paint these shutters, homeowners need to purchase an exterior grade latex paint and primer, notes ExteriorSolutions.com.
Before painting vinyl shutters, they must be taken off of the house and exposed to direct sunlight before, during and after the project. The best temperature to paint vinyl siding is between 60 and 90 degrees Fahrenheit.
