Don’t let your fencing get to this point.


We often get  inquiries about rust removal on metal rails, fences and gates.  New metal railings, fences and gates can be costly.  Some customers have fairly new metal fences and are surprised at the amount of rust that sometimes develops in 6 months or less.   This happened to a Rust Doctor team member with a gate they purchased this summer. Rust had developed in a short time. In this case, the rust started where the upright and cross piece met and was welded together.

It’s important that when you are ready to re-furbish your fences and rails, that you take to steps to remove rust permanently.  Here are the steps for success for rust removal.

  • Clean off the loose rust and paint with a wire brush. If the rust is fairly new, you may be able to use a power washer to loosen up the flakes of rust and paint.
  • Use a cleaner/degreaser like the Grease Doctor. You want to be sure the surface is free of dirt and any oil and grime that may be present. Thoroughly rinse the surface with water.
  • Once dry, apply the Rust Doctor. A trick  to make painting the rails and decorative surfaces easier is to use a painter’s mitt. Painting intricate pickets or rails can be difficult, so using the mitt makes the job go faster. The rusted areas will turn black.  It is best to apply the Rust Doctor to the whole surface of the project. When Rust Doctor is applied, it also leaves a clear primer on the surface. You can decide to leave it black, or paint the surface with any paint type or color.

Be sure you get the paint mitts for this type of job

  • Wait 24 hours for the Rust Doctor to dry or cure. Rust Doctor is dry to touch in 30 minutes, but not ready to paint until 24 hours.
  • If you choose light colored latex paint, such as white, you will need to use a stain blocking primer. This will prevent any tannin staining. This only applies when using a latex paint on the surface. You can skip this step if using an other types of paint or a dark colored latex paint.
  • You can weld on a surface that has been treated with Rust Doctor if the entire treated surface is rusty.
  • Be sure to figure out how much Rust Doctor you will need before ordering. A quart will cover 50 square feet and a gallon will cover 200 square feet, only requiring a single coat of coverage. If you need help figuring out how much Rust Doctor will be needed, please contact us. We also have 5 gallon buckets for those large jobs.
  • Step back and enjoy the great job you have completed. Now you will have a rust protected surface that looks great and will last a long time.
