If you’ve ever skipped the step of taping before painting, then you know the frustration of stray smears and messy lines. Save yourself the cleanup and do-overs. Follow these simple steps for using painter’s tape: 1) Test the tape. Be sure that the tape’s adhesive is as strong or weak as your paint job requires. 2) Apply the tape.
