How do you fix a cracked shutter staple? To start, pull out the damaged staple from the louver with a pair of needle-nose pliers. Then use some adhesive (like wood glue or epoxy) to coat the legs of a new staple. weave the staple into the loop on the louver and direct its legs into the same staple holes on the tilt rod.
