Sealing a stock tank will take some time. Livestock is expensive and keeping livestock fed and watered is important to the health of the animals. When the water tank that feeds the livestock leaks it can be a serious issue. Sealing a leaking water tank is a labor intensive operation, but one that be accomplish for little expense.

Step 1 – Prepare the Tank for Sealing

Find the drainage device or connector on the bottom of the water tank. Connect a hose to the connector, or turn the device counter clockwise to open the drain valve. Drain the water from the tank completely. Clean an area next to the tank to use as a work area and make arrangements for the livestock to water in an alternate location for a day or so. Disconnect any attachments that you might have on the water tank, such as a water heater, or water circulator. Keep track of the method used to remove these things and store the connecting anchors in a safe place for reuse. After the water has been drained and the attachments safely removed, dislodged the water tank from the struts it sits upon and place the tank down on the ground in the area you had cleared out earlier.  

Step 2 – Clean the Tank

While the tank sits on the ground, clean it first of any large debris with a broom or a vacuum. Then wash it out and clean it as best you can. Turn the tank over and let it air dry for a period of time. Gather together the tools needed to scrap the inside of the water tank, the wire brush and the scrubbing sponges. The object is to now scrape the old paint off the inside of the water tank as best you can. Using the wire brush and the scrubbers, take as much of the paint and old finish off as you can. This step is labor intensive and you may want to take a break from time to time. After you have scraped as much as you can, rinse the tank and smooth out the inside with a rag. Let the tank air dry.

Step 3 – Seal the Tank

Once the tank is again dry, find the coating mix you had purchased in the store. Liberally brush on the sealer to the inside of the tank. Use the roller and other tools as needed to coat the entire inside of the tank. Repeat with a second coat after the first has dried.

Step 3 – Assemble the Water Tank

After the seal has dried, it is time to reassemble the water tank assembly. Place the tank back on its struts, and anchor any attachments back into place on the water tank. Reinstall any electric hook up. Refill the water tank, and drain. Refill a second time and let the animals enjoy the newly refurbished tank.
