Wrapping tape around the metal part of your paintbrush is a helpful hack to prevent paint from seeping into the ferrule (the metal part that holds the bristles) and ruining your brush. This technique creates a barrier between the paint and the metal, making cleanup easier and extending the life of your brush. It’s particularly useful when using water-based paints that can easily seep into the ferrule. Simply wrap a few layers of tape around the metal part, leaving a small gap between the tape and the bristles. After painting, remove the tape carefully to reveal a clean brush ready for your next project
