How to Repair a Leaking Film Developing Tank

If you’re a photographer, you know that developing tanks are essential for processing film. But what happens when your developing tank starts to leak? Don’t worry, it seems to be a common problem, and you can fix it yourself with a few simple steps.

Here’s what you’ll need:

• A leaking developing tank
• Silicone sealant
• Masking tape
• Water and washing liquid solution in small cup
• A clean cloth

Instructions:

1. Clean the developing tank thoroughly.
2. Apply a strip of masking tape along the bottom of the red band on the developing tank.
3. Apply another strip of masking tape about 5mm below the red band.
4. Squeeze a bead of silicone sealant in between the two strips of masking tape.
5. Smooth out the bead of silicone sealant with a wet finger dipped in water and washing liquid solution.
6. Allow the silicone sealant to dry completely.

Once the silicone sealant has dried, your developing tank will be leak-proof. You can now use it to develop film without worry.

Here are some additional tips for repairing a leaking developing tank:

• Make sure the developing tank is clean before you start. Any dirt or debris can interfere with the bonding of the silicone sealant.
• Apply the silicone sealant evenly. A thick bead of silicone sealant will take longer to dry and may not be as effective as a thin bead.
• Smooth out the silicone sealant with your finger. This will help to create a smooth, even surface that will be less likely to leak.
• Allow the silicone sealant to dry completely before using the developing tank. This will ensure that the sealant is fully cured and that the developing tank is leak-proof.

By following these simple steps, you can easily repair a leaking developing tank and get back to developing film.
