How do you stop the rust from spreading and cover a hole approximately by in wall of an above ground pool?

To stop the rust from spreading and cover a hole approximately by inch in the wall of an above-ground pool, follow these steps:

1. Prepare the area: Clean the rusted area and the surrounding area with a wire brush to remove any loose rust and dirt.

2. Sand the area: Use sandpaper to smooth out the surface of the rusted area and remove any remaining rust.

3. Apply a rust converter: Paint the rusted area with a rust converter. This will help to stop the rust from spreading and convert it into a stable compound.

4. Let it dry: Allow the rust converter to dry according to the manufacturer's instructions.

5. Apply fiberglass patch: Cut a piece of fiberglass patch that is slightly larger than the hole in the wall. Apply a thin layer of epoxy adhesive to the back of the patch and then place it over the hole in the wall.

6. Press firmly: Press the patch firmly in place, ensuring that there are no air bubbles underneath it.

7. Apply more adhesive: Apply another thin layer of epoxy adhesive around the edges of the patch to ensure a good seal.

8. Let it dry: Allow the adhesive to dry completely, according to the manufacturer's instructions.

9. Sand and paint: Once the adhesive is dry, sand the patched area until it is smooth. Then, paint the entire pool wall to match the existing color.

This method should effectively stop the rust from spreading and cover the hole in the wall of your above-ground pool.
