What You'll Learn
Clean the pan thoroughly with soap and water
To repair a swamp cooler pan, you must first clean it thoroughly with soap and water. Here is a step-by-step guide:
Step 1: Prepare the swamp cooler for cleaning
Start by unplugging the cooler and turning off the water supply. This is an important safety measure and will also make it easier to work with the swamp cooler.
Step 2: Remove the panels and pads
Take off the side panels of the swamp cooler. Then, remove the fiber or cooling pads. These pads should be replaced regularly, ideally every 3-6 months during heavy use, to ensure optimal cooling and prevent bacteria or mould growth.
Step 3: Drain the water
If your swamp cooler has a drain plug, open it to let the water drain out. If there is no plug, use a hose to siphon the water out. Make sure to drain the water outside, especially for portable swamp coolers, to avoid any water damage to your home.
Step 4: Clean the water pan and reservoir
Use a brush or small vacuum cleaner to remove any debris, dirt, or calcium buildup in the water pan and reservoir. This step is crucial as debris can cause blockages and lead to unclean water circulation.
Step 5: Soak the reservoir with soap and water
Create a cleaning solution by mixing mild soap and warm water. You can also add distilled white vinegar to the mix, which is especially useful for breaking down mineral deposits. Soak the reservoir with this solution for about an hour.
Step 6: Scrub and rinse the reservoir
After soaking, use a scrub brush or cloth to clean the reservoir thoroughly. Pay extra attention to any stains or buildup, scrubbing harder if necessary. Rinse the reservoir well with clean water to remove any remaining soap or vinegar solution.
Additional Tips:
- If you have hard water, consider using a mild detergent designed for swamp coolers to prevent future mineral buildup.
- You can also mix a solution of vinegar and salt and apply it to the swamp cooler, scrubbing with a wire brush to remove rust.
- For extensive rust damage, consider repairing with fibreglass or fabricating a new pan from sheet metal or rigid plastic.
- To prevent leaks, use a drip collector pan with a drain outside the unit and explore using a self-adhesive roofing membrane inside the pan for added protection.

Use a wire brush to remove rust
To repair a swamp cooler pan, you can use a wire brush to remove rust. This is a crucial step in preparing the surface for further treatment, such as painting or sealing. Here are some detailed instructions on how to effectively use a wire brush to remove rust from your swamp cooler pan:
First, it is important to clean the pan thoroughly. Use a pressure washer or a high-pressure hose nozzle to remove any peeling paint, rust, and debris. You can also employ tools like a hand scraper, oscillating multitool, or sandpaper for more stubborn areas. Ensure you give it a thorough cleaning afterward to eliminate any remaining oil or debris, ensuring the surface is ready for the next steps.
Next, use a wire brush to focus on areas with remaining rust. You don't need to remove all the rust, just the loose bits. A wire brush is ideal for breaking down and removing rust particles, so apply firm pressure and work the brush back and forth across the rusty areas. You can also dip the wire brush in a solution of vinegar and salt, which will help loosen and dissolve the rust, making it easier to remove.
After brushing, rinse the pan thoroughly with water to remove any remaining cleaning solutions. This step is important to ensure no residue is left behind that could interfere with the adhesion of paint or sealant.
Once the pan is dry, inspect it for any remaining rust spots. If necessary, repeat the process of using the wire brush and vinegar-salt solution to ensure all rust is removed. A rust-free surface is essential for effective repair and protection.
Finally, you can proceed with further treatment, such as applying epoxy-based sealers, paint, or liquid rubber products, to ensure your swamp cooler pan is protected from future rust and leakage.
By following these steps and using a wire brush effectively, you can successfully remove rust and prepare your swamp cooler pan for further repair and protection.

Apply a solution of vinegar and salt
To repair a swamp cooler pan, you can apply a solution of vinegar and salt. This is a good method for cleaning the unit and removing rust.
First, mix a solution of vinegar and salt. The vinegar should be white vinegar, and you will need enough to soak the reservoir. You can also add some soap to the mixture if desired. Next, remove the panels and fiber pads from the swamp cooler and unplug the cooler. Turn off the water supply and remove any remaining water from the cooler.
Now, apply the vinegar and salt solution to the affected areas of the swamp cooler pan. Use a wire brush to scrub the surfaces and remove any remaining rust. Leave the solution to sit in the water reservoir for about an hour. Then, drain the solution into a bucket and scrub away any remaining stains or buildup with a brush or cloth.
Rinse the pan with clean water and ensure that all the solution has been removed. You can also use mild soap and warm water for additional cleaning if needed. Finally, dry the pan thoroughly before reassembling the swamp cooler and reconnecting the water supply.

Seal the pan with a spray
If your swamp cooler pan is leaking, you can use a spray to seal it. First, drain the water from the swamp cooler to prevent cracking and other serious problems. Next, disconnect the water source and the power. Then, remove any dirt and debris from the pan to make it easier for the spray to stick to the surface. If there are any rusty spots, scrub them with a solution of vinegar and salt and use a wire brush to remove the remaining rust. You can also use a product like Naval Jelly to get rid of corrosion.
Once the pan is clean and dry, you can apply the spray. If there are holes in the pan, you will need to patch them before sealing the rest of the pan. You can use roofing cement or tar to patch the holes. Alternatively, you can use a product like Liquid Rubber, which can be applied with a reinforcement cloth to add strength. Once the patch is dry, you can use an evaporative cooler spray or a rust-resistant spray paint to seal the pan. Apply enough coats for moisture protection—this may vary depending on the product you are using. For example, one source recommends using three coats of spray paint, while another suggests using two coats of Flex Seal rubberized coating. Make sure to follow the manufacturer's instructions for the product you are using.
In addition to spray paint and rubberized coatings, there are other types of sprays and sealants that can be used to seal a swamp cooler pan. For example, you can use a product like Apoc 264 or Redgard, which are applied with a brush or roller. You can also use a tape product like Gorilla Patch & Seal Tape, which is applied directly to the pan. It's important to read the instructions for any product you use to ensure that it is suitable for use on a swamp cooler pan and to follow any safety precautions.

Use a reinforcement cloth for strength
If your swamp cooler pan has deteriorated, you can repair it with a reinforcement cloth for added strength. This method is ideal for pans with small holes and leaks.
First, you will need to purchase a liquid rubber product that can be applied with a reinforcement cloth. This product is water-based, non-toxic, and UV stable. It is also designed to prevent rust. You can find this product at Johnstone Supply.
Before applying the liquid rubber, ensure that your swamp cooler pan is clean and dry. You can clean the pan with soap and water and remove any remaining rust with a wire brush.
Once the pan is prepared, apply the liquid rubber product according to the manufacturer's instructions. This may involve using a reinforcement cloth as a strength member.
After the liquid rubber has dried, your pan will be permanently repaired and protected from rust. This method provides a strong and durable solution for repairing swamp cooler pans.
In addition to liquid rubber, you can also use fiberglass resin and cloth to repair your swamp cooler pan. This method involves using products such as Apoc 264 or Redgard to seal and reinforce the pan.
