How to Restore a Rusty Wrought Iron Fence

A wrought iron fence is meant to last for years with proper care. The worst enemy of wrought iron is rust. Rust can severely damage your wrought iron fence and ruin its appearance. You can restore a rusty wrought iron fence to its original appearance and also protect it from future damage.

Step 1 - Remove Rust and Old Paint

Use a paint scraper to remove any loose or peeling paint. Use a wire brush to scrub rusted areas and loosen rust and old paint. If the rust is heavy, use a drill with a wire wheel to loosen it. Make sure to get into tight areas and joints where rust is most likely to be found.

Start with coarse grit sandpaper to sand the entire fence, concentrating on rusty areas. Some areas of deep rust may require sanding all the way down to the metal. You may want to use a drill with a sanding wheel to remove deeper rust. When you can't see anymore rust, go over the fence again with a medium grit sandpaper to remove any remaining rust or flaking paint and smooth any rough areas.

Buff the entire fence with fine steel wool in a circular motion to smooth and prepare it for painting. Rinse with clear water.

Step 2 - Neutralize Rust

The key to restoring a wrought iron fence is to remove all the rust. Any rust left behind will continue to spread and ruin the wrought iron even after finishing. Even though you can no longer see any rust on the wrought iron, there may still be some tiny particles remaining.

Mix a commercial rust neutralizer per package instructions in a bucket. Dip the wire brush into the solution and scrub the entire fence in a circular motion to neutralize any remaining rust.

For those who prefer not to use chemicals, you can use a solution of half lemon juice and half white vinegar to neutralize rust. Wipe down the entire fence with the vinegar and lemon juice solution and allow to dry for 1 hour. Wash off with soapy water and allow to dry completely.

Step 3 - Prime and Paint

Paint the entire surface of the wrought iron with an even coat of rust inhibiting primer for metal and allow it to dry at least 4 hours. Apply two fairly thick coats of rust resistant paint over the primer using a medium bristled paint brush. Use smooth, even strokes to cover all areas. Allow the paint to dry completely between coats.

Step 4 - Maintenance

Wash your wrought iron fence with soapy water twice a year. Oil latches and springs with mineral oil. Use steel wool to buff any scratches or beginning signs of rust and neutralize with lemon juice and vinegar. Use matching rust resistant paint to touch up small areas after neutralizing.

Take care of your restored wrought iron fence and it will stay beautiful for many years.
