It is simplest to fix a rusting above-ground pool while the rust stains are small. Should you catch it in the first stages, the fix will stop the rust from spreading. Let it go too long and holes may develop, complicating the fix. If the rust is within the pool walls, possibly brought on by a leaking liner, you will need to empty the pool and remove the liner.
Inspectng the Pool Walls
Drain the pool. Reverse your swimming pool pump to empty the pool or set up a siphon. Allow several hours to overnight for this measure, depending on how big your pool.
Remove the top edging that holds the liner in position. Remove the pool liner carefully to avoid tearing it. Inspect it . If your liner is damaged or old, this is a fantastic time to replace it. Otherwise, fold it neatly for replacement later.
Inspect the whole pool exterior and interior surfaces for rust and mark even small spots for fix.
Patching Small Rust Holes
Remove the rust round rust holes with a metal brush or chemical rust remover. Rinse the chemicals away and permit the area to completely dry.
Patch small holes with epoxy putty. Knead the putty to blend thoroughly and push it through the hole from the inside. Smooth the overflowing putty despite the pool on both sides.
Allow the putty to cure for 24 hours.
Sand the putty on both sides, creating a smooth transition with the pool walls.
Remove Rust and Repaint
Remove small stains of rust with a wire brush. For widespread rust, then use a chemical rust remover. Rinse off the chemicals and permit the area to dry.
Paint the place with a rust-proof primer. For small stains, spray paint is easy to use. Allow the primer to dry.
Paint the exterior wall with matching paint. If your rust stains are extensive, you may wish to paint the whole pool exterior.
Replace the pool liner when the paint has dried.
