How to Seal Stock Tanks

By Sharyl Stockstill | Updated September 26, 2017

Items you will need

  • Food-grade liquid coating

  • Paint brush

  • Gloves

  • Wire brush

Water for livestock is not a luxury, it's a necessity. Animals must have a readily available source of fresh water. A leaking stock tank can be expensive to ignore and more expensive to replace. By using a sealant, new tanks will last longer, and a leaking tank can be repaired.

Drain water from the tank, and allow it to air dry. Use the wire brush to scrape off algae, dirt and rust. Remove any debris from the stock tank.

Paint a one-eighth inch layer of the rubber coating over the entire interior surface of the tank with the brush. Allow to dry thoroughly.

Refill stock tank with fresh water.
