If you would like to refinish your foam planters, you must select the right coating, or you could end up ruining the very item you are attempting to enhance. Because planters are generally located outdoors, they are exposed to varying temperatures and weather conditions. You must select a durable enamel formulated to hold up under relatively harsh circumstances. Unfortunately, some enamels can melt foam and plastic. Know the right materials to use and the proper way to apply them, or you could end up causing unforeseen damage.
Things You'll Need
