Steps to Paint Rusted Metal Surface with Aerosol Spray

Metal is an excellent, useful, eco-friendly, and easily retained material. One problem with it, though, is that most metal rusts sooner or later. If it holds even a small quantity of iron, the metal will oxidize when exposed to air and humidity. Oxidation on iron and metal is easy to find by its reddish brown color and its tendency to powder or flake off. Rust makes solid bubbles under paint, eventually erupting into scratches that erode the metal until it crumbles. If there is rust in your life, whether on tools, metal furniture, fittings, posts, or fencing, it is good to deal with it as soon as you can. Before you start, here are a few steps to take when painting rusted surfaces.

It is significant to apply the primer evenly, fully covering the metal surface. If even a small area of metal is exposed, rust will one more time form, forcing a repeat of the procedure. It will save your time in the long run if you make sure a rust-free surface at this stage in the procedure.

Helpful Tips:

  • Wear a mask to defend yourself from debris in the air while sanding.
  • For railings and fences, remember setting up a large piece of cardboard, lightweight wood, or hanging a drop cloth or sheet as a shield against overspray that would blow onto different objects. 
  • If you scrape, sand or remove old paint, you could release lead dust. Lead is toxic. Contact to lead dust can cause severe illness, such as brain damage, especially in children.
  • After the usage of aerosol primer (or paint), tip the can upside down and depress the nozzle for a few seconds until paint stops popping out. Next, wipe off the nozzle with a cloth. This avoids the nozzle from being clogged whenever you use the can.
