Protecting Steel Garage Doors from Rust05/26/2015 Back To Blog
Most modern overhead garage doors have panels as well as hardware parts made from steel. While this alloy is super strong and retains good durability, it is not fully protected from the surrounding environment. When it is exposed to air and moisture for a long period of time, it begins to rust and then corrode. While rust can be effectively removed, it is better to take preventive measures. Find out what these are.
Complete Effective Protection
The most important protective measure is the painting of the steel panels. This must be done right after garage door installation. You would not want to leave the unit exposed to the elements even for a few days. The choice of paint is extremely important. Exterior-grade product must be used. Only this type of paint provides effective protection from moisture and consequently from rust. Check whether the manufacturer of the unit has additional requirements. Most often, the use of latex-based paint is required.
Both the exterior and interior surfaces of the garage door panels must be painted for best results. All sections must be covered. It is crucial for the paint to be left to dry before the door is operated. Most modern products take around eight hours to dry, but you may want to leave the paint to dry overnight just to be on the safe side. The panels must be repainted every year.
The addition of weather seals is another major protective measure to adopt. The seals not only block water from getting inside but reduce the risk of condensation to provide even greater protection from rust. They actually prevent any moisture from affecting the sides of the panels. It is best to use not only a vinyl bottom seal, but also side and top weather strips.
The metal garage door parts do not require special protection from rust. This is because they are made from galvanized steel which has protective zinc coating. Still, it pays off to provide lubrication maintenance since the lubricant prevents the moving parts from coming in direct contact with moisture. Another really important measure to take is to clean and rinse the garage floor and the driveway properly on a regular basis. This is due to the presence of chemicals on these surfaces which can get into contact with the lower parts and damage their protective coating.
Finally, keep in mind that the protection from rust is an ongoing process. In addition, to repainting the panels and providing lubrication on a regular basis, you must change the weather seals when they wear out.
