Step-by-Step Repair Guide

​

  1. Assess the Damage

    • Inspect the gate/railings for rust, dents, loose fittings, or broken welds.

    • Test hinges, latches, or moving parts for functionality

  2. Clean the Surface

    • Remove dirt, grime, and loose paint with a wire brush or sandpaper.

    • Use a degreaser if there’s oil or grease build up.

    • Rinse and let it dry completely.

  3. Remove Rust

    • Scrub rusted areas with a wire brush or sandpaper until you reach bare metal.

    • Apply a rust converter to any remaining rust spots to neutralize it.

  4. Fix Structural Issues

    • Loose Bolts/Screws: Tighten with a wrench or screwdriver. Replace if stripped.

    • Bent Metal: Use a hammer or pliers to reshape minor bends. For severe damage, consider cutting out and replacing the section.

    • Broken Welds: If you can weld, reattach the parts. Otherwise, consult a professional or use metal epoxy for a temporary fix.

    • Cracks/Holes: Apply metal filler, let it cure, then sand smooth.

  5. Prime and Paint​

    • Once dry, coat with outdoor-grade metal paint (2-3 thin layers work best). Match the colour to the existing finish if desired.

  6. Apply a rust-inhibiting primer to all bare metal surfaces.

  7. Lubricate Moving Parts

    • Use a lubricant (e.g., WD-40) on hinges, latches, or sliding mechanisms to ensure smooth operation.

  8. Final Inspection

    • Check stability and alignment. Ensure the gate opens/closes properly and railings are secure.​

​

Tips

  • Work in a well-ventilated area, especially when painting or welding.

  • If replacing sections, source matching metal (e.g., wrought iron, steel) from a hardware store.
