Powder coating is ideal for application on metal surfaces due to its multiple benefits. This type of finishing is attractive because there are no apparent differences in appearance between vertically and horizontally coated surfaces. Inconsistency is a common problem for surfaces coated with liquid paint. Also, the coatings created using free flowing powder are thick and protective.
Additionally, there are no solvents present in this category of finishing products, so there is no significant release of harmful VOCs. In general, powder coatings are durable and will provide long-term service. However, the exact duration of performance will depend on your care and maintenance practices. Here are some simple tips on increasing the service life of your powder coated surfaces.
Clean the Surfaces with Care
You should clean your powder coated surfaces on a regular basis. The removal of accumulated dirt and grime will ensure that the aesthetic appeal of the surface is retained. In addition, regular cleaning will minimise the risk of staining and general deterioration. If the powder coated surface is relatively small, you can clean the surface with a soft nylon brush and mild soap.
If you are dealing with wide areas, you should consider acquiring a pressure washer for the work. It will wash away dust and grime quickly and efficiently. When cleaning a powder coated surface, you should avoid harsh detergents or solvents. If you are uncertain about any cleaner, consult the manufacturer. Also, rinse with filtered water and wipe the surface to avoid leaving stains.
Examine and Repair Scratches
You should perform routine inspection of metal surfaces with powder coating regularly. Often, the service life of finishing is cut short by damage from external sources such as mechanical impact or chemical contact. If the problem is recognised early, the damaged area can be repaired and the surface restored. However, if you rarely check the coating, you will only notice the widespread damage.
You can repair localised scrapes and scratches without professional assistance. Use sandpaper to smooth the damaged area and remove traces of rust. Once the surface is smooth, apply metal primer to conceal the scuffs and seal the metal. Finally, apply metal enamel in a colour that matches the original powder coating.
Apply Wax Coating
If your powder coated surface often comes in contact with damaging elements such as sunlight, rainwater, saline water and general pollution, you should apply some protective wax. Purchase high-grade wax with ultraviolet inhibitor and nonabrasive properties. A light evenly-spread coating will provide optimal protection from external pollutants.
