  • Step 1: Prepare the area. Remove any old silicone from the work area. This can be done with a utility knife. Any contaminants like oil and grease could prevent the silicone from bonding so clean the area thoroughly with alcohol.

  • Step 2: Open J-B Weld Clear Silicone and attach nozzle. Cut end of nozzle as needed to create desired amount to be dispensed.

  • Step 3: The tip should be slightly above the surface, nearly touching. As you begin to dispense the tube, watch the flow of caulk. With one steady motion, move J-B Weld Silicone Sealant straight along seam, creating a uniform bead. Create a uniform bead the entire length of seam. Do not stop until you reach the corner. Be careful not to apply too much.

  • Step 4: Wearing gloves, gently pull your finger along the silicone to complete the seal. Wipe away excess silicone from your finger and work area, and allow to dry.
