One of the most asked questions to manufacturers of Aluminum Composite panels is whether their panels come in many colors and whether there is a possibility of re-coloring them. It is an important question though to every consumer of such products.
To recolor panels is just an easy straight forward affair that does not require any great master skill. Aluminum Composite Panels have two common methods of re-coloring. These are spray painting and flood coat in sign vinyl.
The quickest way of changing the color of these panels is laminating the aluminum in sign vinyl. The quality of the final product after spray painting depends on your patience, skill, and effort that you dedicate to the work. Either way, you can choose the method that you prefer. Below we are going to discuss the spray painting method of re-coloring Aluminum Composite Panels
- Place the Aluminum panel on rubber or mat to prevent its surface from been scratched in a place away from direct sunlight. The place must be well ventilated too.
- Clean the aluminum surface thoroughly with soap and water. This is to remove the grime and grease.
- Use an 180 to 220 grit sandpaper to polish the surface of the aluminum.
- Use a plastic container to mix the primer components
- Use a filter funnel to filter the mixed primer into the paint can of the spray gun.
- Ensure to protect yourself before you begin spraying. Wear protective eyewear to protect your eyes then apply etch primer to the surface of the aluminum using the paint spray gun. Etching primers are not used to fill scratches, but they create an adhesion surface on the aluminum metal surface.
- Choose the color you prefer. Ensure the paint nozzle is perpendicular and about 10 to 13 inches to the surface of the aluminum.
- All through, adjust the equipment as you would and perform a spray test. To ensure even application of the paint, move in along straight strokes while applying the paint.
- To protect the aluminum composite panel from weather variations, finish the work with a coat of paint enamel.
- When spraying the paint, always paint a thin layer first and where needed add additional layers later. This is because a heavy coat of paint peels easily when dry and it may dry unevenly.
