Repairing pool wall rust is easy and can give your swimming pool a new life. Preventing complete pool replacement can save a ton of money. When surface rust appears on the outside of the wall of an above ground swimming pool, lightly brush it with a wire brush. Then spray a little bit of enamel spray paint on the wall itself. This will hinder the spot from growing at a faster pace.

When you change the pool liner you will likely encounter more rust than you could see on the outside of the pool wall. This is all right. Just get down and dirty and spray paint all of the rust spots. Pool stores would have you think that you will have to throw the pool in the garbage, but this is not the case. Rehabilitate the wall, install a new liner, and you are almost as good as new for nowhere near the cost.
