To handle a gap in a silicone joint, one can first assess the size of the gap. If it is a small gap, it can be filled with additional silicone sealant using a caulking gun. For larger gaps, a backer rod can be inserted into the gap before applying the silicone sealant to ensure proper adhesion. It is important to smooth out the silicone sealant with a tool or finger to create a neat finish and ensure a watertight seal. **

To handle the gap in a silicone joint, you can use a caulking gun to apply more silicone to fill in the gap.
