sand the surface

It is important to sand the surface to remove the shine from the outer layer. By removing the glossy layer, you allow the paint to adhere much better to the metal. Once the paint is completely dry, you can always add a thin coat of gloss topcoat to get that shiny look back.

Protect other surfaces

Tape off any furniture you don't want painted. In this way, you reduce the possibility of an accident.

prepare the surface

Adding a primer before painting will help the paint adhere to the surface. If you notice that the primer comes off or smudges easily, it probably means you need to sand the surface a bit more.

spray your paint

It's best to use spray paint for this job to ensure the paint spreads evenly. It also makes getting paint into those hard-to-reach corners a lot easier.

How to Restore a Faded Powder Coating

While powder coating is extremely strong and durable, it does fade over time. Fortunately, restoring powder coating once it wears off is relatively easy. To successfully restore the coating, you must examine the aluminum closely to determine where restoration is needed.

You should also clean the surface before applying any type of restorative polish. Also, it's important to remember to cover all areas that don't need restoration. Then lightly sand the aluminum, cleaning after each sanding pass to remove any dirt.

Once you have fully prepared the area, you can apply the powdered restorative coating where needed. You can apply as many coats as you see fit and then let dry before unmasking and cleaning the area.

How long does powder coating last outdoors?

In theory, a powder coating should last up to 20 years. However, there are several factors that can shorten the lifespan of powder coating. Excessive exposure to ultraviolet light, sitting in inclement weather, and not cleaning aluminum regularly all contribute to reduced life.

To promote the longevity of your aluminum outdoor furniture, be sure to clean it regularly, avoid placing it in direct sunlight, and protect it when bad weather is forecast.

Can the dust layer be removed?

final thoughts
