A rusting nail that is still doing its job is harmless, right? Well, that very nail may actually be detracting from the overall appearance of the fence. The rusting nails can stain the painted surface. Replacing the nails may be quite the ordeal, but you can cover them to improve the appearance of the surface.

How rust forms
If the nail is non-galvanized, it is more likely to exhibit signs of rust. Over time, the moisture conditions can cause staining to bleed to the top coat from the rusty nail heads. The appearance of those nails makes the paint appear dull. The weathered nails have to be treated in order to diminish the appearance of the rust.
Keeping your building looking its best
The building’s outward appearance is what gives it curb appeal. First-time visitors are taking in every aspect of the building, including its aesthetic appearance. To maintain the exterior, a quality paint job is a necessity. If you are preparing to repaint the structure, you can caulk the rusty nail heads prior to painting them to minimize future rusting.
Caulking the Nails
Some people choose to sand the nail prior to applying the primer to it. Sanding the nail removes the rust from nail’s surface. Removing as much of the rust beforehand as possible will increase the performance of the primer in thwarting off rust. Before you begin the paint job, caulk each nail with a water-based acrylic caulk. This should before any priming or painting is done. A rust inhibitive primer can be applied to both the surface and the nails before the paint job begins. The primer contains materials that counter the nail's capacity to develop rust. The rust is suppressed and can never reach the surface. The stainblocking primer should be applied directly to the area where the nails are located. It is recommended that multiple coats be used to prime to prevent nail head rusting. Adding more layers further protects the surface from staining. Now you are ready to repaint the area.
Prevent The Rust
The rust will always rise to the top over time. This is especially the case when the nails have been sanded. The elements and the un-galvanized metal increase the likelihood of rust forming and spilling over into the painted surface area. Caulking the nails prior to the paint job and priming them eliminates nail head rusting problems.
