Painting Galvanized Metal That’s Rusted 

Galvanized metal is a commonly used metal for piping, building support beams, ducts for air conditioning and heating, handrails, barriers and even roofs. Because galvanized metal is so long-lasting it works well in areas that need to withstand extreme weather conditions.

In Toronto galvanized metal is mainly used for handrails and support beams around the exterior of your home. Although this type of steel is treated with zinc oxide to last in harsh climate changes over time the zinc oxide within the metal can wear away and begin to rust. If you are going to repair rusted galvanized metal you’ll need to act quickly before it spreads and becomes much more difficult to fix. So, keeping reading to learn about painting galvanized metal that has worn from age.

1. Wipe, Sand and Scrape

  • Firstly, with your rag, wipe away any dust, dirt or debris from the galvanized metal so that you can have a clean area to work with.
  • If you want to give your galvanized metal a good cleaning with something non-toxic, white vinegar actually works really well. It’s the acidity of the vinegar that can actually help the paint to properly adhere to the galvanized metal later on.
  • Secondly, with your sandpaper or wire brush sand along the galvanized metal by vigorously sanding right to left along the entire length of the rusted metal. You want to take your time with it to be sure you sand away any loose paint and rust chips. You may choose to use an electric handheld sander to sand away the rust/loose paint – whichever you find easier. Make sure you end up with a smooth surface after sanding so it will be easier to proceed on to the next step.

TIP:

  • The good thing about sanding the rusted galvanized metal is that you usually won’t come across any seriously rusted metal because the zinc oxide treatment prevents this from happening. So using sandpaper instead of a handheld sander is just as efficient.

2. Prime

  • Thirdly, using your metal primer and a paint brush, brush on the primer with 2 coats to seal and protect any future rust from reoccurring.
  • Tremclad Primer for Galvanized Metal is a good choice.
  • Allow to dry and you have properly prepped your rusted galvanized metal for painting!

3. Paint! 

  • Fourthly, it’s time to paint your galvanized metal.
  • When thinking about what type of paint will properly adhere to it, you want to go for an acrylic paint. You can try one of the oil based paints on the market, but often times the metal surface sheds the paint over time.
  • Once you have your paint, you can either use a brush or a roller to paint it on.
  • There are also lots of specialized spray paints that can be great for galvanized metal.
