Usual glass planters can be turned into chic faux concrete ones with patina. First of all, give your pots a quick coat of spray pain. Once that is dry, apply the primer. Apply two coats, waiting a half hour between each coat. After the second coat you have to wait 12 hours for it to fully dry. Let them sit overnight and get started back up again the next day. Use primer and then the oxidizing paint. Again, apply two coats and once that is dry, spray them with the rust activator. The rust activator is what gives the finish the patina look and brings the rust to life. Keep reading the tutorial in the source.
