You can spray paint plastic bins—and that’s a great way to refresh older bins or update a space. The most important part of painting plastic bins is the prep work. Plastic surfaces are slick and won’t “grip” paint without sanding. Choose 180 to 220 grit sandpaper and work by hand. Wash the bins to remove fine particles, then hit them with your favorite spray paint. Consider using chalkboard spray paint to make it easy to label the bins.
