TJ’s Tips - How to paint a metal gate


Materials you'll need:

  • Drop cloths or plastic sheets
  • Painter's tape
  • Sandpaper or a wire brush
  • Rust converter (if applicable)
  • Metal primer
  • Paintbrushes or paint rollers
  • Metal paint (choose one suitable for outdoor use)
  • Paint tray
  • Paint thinner or mineral spirits (for cleanup)


Step 1: Prepare the area

Start by preparing the area around the metal gate. Lay down drop cloths or plastic sheets to protect the ground from paint drips or spills. If there are any nearby surfaces you want to keep paint-free, cover them with painter's tape.



Step 2: Clean the gate

Before painting, clean the metal gate thoroughly to remove any dirt, dust, or grease. Use a mild detergent mixed with water and a scrub brush to wash the gate. Rinse it with clean water and allow it to dry completely

Step 3: Remove rust (if applicable)

If the gate has any rust spots, use sandpaper or a wire brush to gently remove the rust. Be sure to wear gloves and a mask to protect yourself. If there are significant rust patches, consider using a rust converter according to the product instructions.

Step 4: Sand the surface

To help the paint adhere better, lightly sand the entire surface of the metal gate using fine-grit sandpaper. This will create a slightly rough surface that promotes paint adhesion. After sanding, wipe away any dust using a clean cloth.

Step 5: Apply primer (if required)

Apply a coat of metal primer to the gate. The primer helps with paint adhesion and provides additional protection against rust. Use a paintbrush or a paint roller to apply the primer evenly across the surface of the gate. Allow it to dry according to the primer's instructions.

Step 6: Paint the gate

Once the primer is dry, it's time to apply the paint. Stir the metal paint thoroughly to ensure it's well mixed. Use a paintbrush or paint roller to apply the paint in thin, even coats. Start from the top and work your way down, using long, smooth strokes. Allow the first coat to dry completely before applying additional coats. Follow the manufacturer's instructions regarding drying times and the number of coats needed.

Step 7: Clean up

After you finish painting, clean your brushes and rollers with paint thinner or mineral spirits, following the product instructions. Dispose of any used drop cloths or plastic sheets properly. Allow the painted gate to dry completely before removing any painter's tape.

Remember to always read and follow the instructions provided by the paint and primer manufacturers for the best results. Painting in a well-ventilated area and wearing appropriate protective gear is also recommended.
