How to Use XFasten Caulking Gun

  1. Prepare the caulk. Cut the tip of the caulk cartridge at a 45-degree angle using a utility knife or scissors. The size of the opening should match the size of the joint you are sealing.
  2. Load the caulk cartridge. Pull back the rod on the caulking gun to release the pressure plate. Insert the caulk cartridge into the gun and make sure that the nozzle is facing forward. Push back the rod back in place until it rests against the back of the caulk cartridge.
  3. Puncture the cartridge. Use the puncture tool to puncture the seal at the top of the caulk cartridge.
  4. Test the trigger. Squeeze the trigger to ensure that the caulk flows smoothly. This will also help to see that the puncture was successful.
  5. Apply the caulk. Position the nozzle at the starting point of the joint or seam you want to seal. Squeeze the trigger steadily as you move the gun along the joint, applying a consistent bead of caulk. Release the trigger before lifting the caulking gun away to prevent excess dripping.
  6. Smooth the caulk (if needed). If a smooth finish is desired, you can use a caulk smoothing tool or your finger (wearing a latex glove) to smooth the caulk within a few minutes of application.
  7. Clean-up. Wipe off any excess caulk with a damp cloth before it dries. Recap the caulk cartridge for future use.
