Some painters believe it is best to remove painter’s tape once the paint has dried. However, it’s best if the tape is removed while the paint is still wet. This prevents the paint and the tape from bonding, which can result in a jagged edge when the tape is removed, taking pieces of paint with it.
If your paint has dried completely, you can still prevent the tape from taking paint chips with it by using a razor blade to break the bond between the tape and the paint. Simply run the blade along the edge of the tape and then pull back slowly to eliminate tearing.
