If it's time to fix up the balcony, why not brighten up tired old outdoor furniture with paint? Colour makes you happy! Paint with the new Panduro Outdoor Paint. METHOD: Start by washing the furniture with paint surface cleaner. Sand any uneven areas. If there are knots in the wood (new wood), the results will be best if you prime with shellac first. Prime iron, steel and sheet metal with Panduro Outdoor Primer for metal. Then you can start painting; stir the paint in the container first! Apply at least two coats of paint; let dry for 8-12 hours between coats. Do not paint in the broiling sun.
