Wrought Iron and Metal Painting in Fort Worth, TX

Rust starts wherever bare metal meets moisture, usually at a scratch, a weld, a hail chip or the bottom of a picket where water collects. Once rust starts, it expands and pushes up the surrounding paint, which lets more water in. In Fort Worth, spring humidity, sprinkler spray and morning dew keep iron wet enough to rust steadily, while summer heat bakes the old paint until it's brittle and cracks. Joints between pickets and rails trap water, so rust often appears there first.

Painting over rust without treating it only hides it. The rust keeps growing under the new paint and pops through within a season or two. That's why rust removal and the right primer make up most of the value in this kind of job. A railing that's properly cleaned and primed can hold paint for many years, while a quick spray over flaking rust rarely survives one summer. Proper prep also slows staining on the masonry below.

We start by scraping off loose paint and flaking rust, then use wire brushes, wire wheels on drills and abrasive pads to clean back to sound metal. Heavily rusted areas may need a flap disc or a small grinder, with care around thin pickets and decorative details. Ornate scrollwork gets detail brushes and abrasive cord so we can reach inside curls and corners. Old paint that's still firmly stuck is scuffed so new coats grip, rather than removed entirely.

Any rust that can't be fully removed from pits and crevices is treated with a rust converter, which chemically turns remaining rust into a stable, paintable layer. The metal is then wiped with a degreaser to remove oils, dust and residue. Iron set in concrete or stucco gets extra attention at the base, where rust often eats the metal from the bottom up, and we seal gaps there to keep water out.

• Scrape loose paint and flaking rust
• Wire brush, wheel or grind to sound metal
• Rust converter in pits and crevices
• Degrease before primer goes on

Bare and converted metal gets a rust-inhibiting primer, either an alkyd metal primer or a direct-to-metal acrylic primer, applied within hours of cleaning so flash rust doesn't appear. For galvanized steel railings, which are common on newer stairs and balconies, we use a primer rated for galvanized surfaces, since some standard primers don't bond well to zinc. Topcoats are either alkyd or urethane-modified enamels, known for hardness and gloss, or direct-to-metal acrylics, which stay flexible and resist chalking in strong sun.

Black satin and semi-gloss are the most common finishes on Fort Worth iron, but bronze, dark green and charcoal are popular too. Darker colors can hide minor surface pitting on older iron. We apply two finish coats so the total film is thick enough to protect edges and corners, where paint naturally runs thin. Handrails get a full cure period before heavy use, since fresh enamel can mark under rings and keys for the first several days.

Spraying covers ornate railings quickly and evenly, but it needs heavy masking and very calm wind, since overspray travels far. On iron fences near cars, pools or neighbors, we often brush and use small rollers on flat bars, or spray with shields and drop cloths in close. Brushing also pushes paint into joints and pits better, which helps on older iron. Stair railings next to brick or stucco are usually brushed to avoid overspray on masonry.

Most metal enamels need surface temperatures above 50F and dry weather. Oil-based enamels can take 6 to 24 hours to recoat, while acrylics often allow recoating in a few hours. Iron in direct sun can get extremely hot in summer, so we work it in the morning or when it's shaded. Gates are worked on in sections so you can still use them between coats. Fresh rails are flagged with tape.
