How To Repair A Rusting Above Ground Pool Wall

Posted on: 24 September 2018

Rust and pools are two words that shouldn't go together, but the truth is, this is something that happens often to above ground pools. Rust is usually the downfall of an above ground pool, since the walls, rails, and columns are usually made of steel. Above ground pools last somewhere around 15 - 20 years, but the end comes when the rust takes over and the walls can no longer contain the water inside the pool. You may be bale to repair the rusted areas and prevent a blow-out in your pool. Read on for instructions to make this repair.

What You'll Need:

  • Sheet metal cut to fit over the rusted area
  • Duct tape
  • Sandpaper
  • Rustoleum spray paint


  1. The rust on your walls may appear unsightly on the outside of your pool, but it's the rust that is inside the pool you really need to worry about. If you have rust inside, you may have had a hole or two in your pool liner. If you are in need of a new pool liner, remove the old one and take a peek at your interior pool walls for rust.
  2. If you spot excessive amounts of rust that appear to go all the way through your pool, a repair may not be a financially sound (or even a safe) idea. You may want to invest in a new pool instead or attempting to repair this type of rust. If there are only a few smaller areas of rust, even if they do go all the way through, you can repair this.
  3. Take a piece of sheet metal cut to fit over the rusted areas plus a few inches all the way around. Hold the piece in place and use duct tape to hold the sheet metal in place and to prevent tearing the new liner. The duct tape will help hold the sheet metal in place until you get water back into the pool.
  4. If you only have superficial rusting on the inside (or even the outside) of your pool walls, take a piece of sandpaper and buff the area smooth to prevent tearing your liner. Then use a can of Rustoleum spray paint to paint over the sanded area to protect the area and smooth it. You can do this on the outside of your walls as well.

Sometimes rusting patches closer to the bottom of your pool can cause your pool walls to lose strength. If you aren't sure how well your pool will hold up with a repair such as this, talk to a professional such as those with All-American Pools about having a new pool installed instead.
