Stripping Old Paint From an Iron Gate

On a gate that has been repainted every few years since the middle of the last century, the first job is finding out how many layers are sitting on the metal. Scrape a patch near the bottom rail and count them under a bright light. That count, which the notes at austin wrought iron gates backyard beans and grains treat as step one, decides whether a chemical stripper, a wire wheel or a blast of media is the right tool for a wrought iron gate in Austin, TX.

Finding out what is on the metal

Old enamel paint from the fifties and sixties was often lead-bearing, so a hardware store test swab is worth running before any sanding or grinding puts dust in the air. Dry sanding is out on any gate that tests positive.

Chemical stripper on flat bar and picket

A gel stripper brushed on thick and left under plastic sheet for the full dwell time lifts several coats in one pass. Flat bar, round picket and square tubing all take it well. Wrought iron has a fibrous grain left from the old puddling process, and that grain holds paint in tiny seams, so a second application on the lower rail is normal. Rinse as the label says and let the iron dry.

Wire wheels and scrapers on the scroll

Scroll work is where the hours go. A cup brush on a grinder is fine on a flat frame, but it skips the inside of every curl. Detail scrapers, brass brushes and dental picks reach in.

What old collars and forged joints hide

A collar is the band that wraps a spot where bars cross, and it always hides paint and moisture under its lip. Tap each joint with a small hammer. A dull sound and a flake of rust scale mean the joint wants a closer look before refinishing, and any loose collar gets re-seated or tack welded before the stripping continues.

Older gates in Hyde Park and Travis Heights

Gates from the bungalow era in Hyde Park and Travis Heights usually still carry their original hardware, and the hinge pin is often painted solid inside its knuckle. Soak it, free it, and keep the pin and bushing together so they can be checked for wear later.

Bare metal does not wait

Stripped iron flashes with surface rust within hours in Austin humidity, and faster after a dewy night. Strip only as much as can be primed the same day. Wipe the bare metal down with solvent just before the first coat.
