Iron railings often look nice in their natural form but you can make them even nicer by painting them. Iron railings often accumulate rust because they are exposed to all types of weather. If you prepare to paint your iron railings properly, you won’t have to repaint them every year. You can also use the following steps to paint other metal objects.
7 Paint the outdoor railings on a nice day that isn't rainy or windy.When warming the railings with the propane torch, don't let the iron get so hot that you cannot touch the railing.
Attach the wire brush onto the drill. Turn the drill on to a high setting and brush the railings.
Spray metal primer onto the railings while they are still warm. Let the primer dry completely.
