FAQ
1. What type of materials can be powder coated?
Typically, any metal object that can hold the electrostatic charge needed to affix the sprayed powder and can tolerate the high heat levels of the curing process. Mild steel, galvanized and electroplated steel, aluminum, stainless steel, and most other steel alloys can be powder coated.
2. How many years does powder coating last?
On average, a high-quality powder coating can last between 10 to 25 years, or even longer in optimal conditions. However, areas with heavy sun exposure or harsh weather conditions may experience a shorter lifespan.
3. What metals can you not powder coat?
Powder coating is a highly effective and versatile method of applying a durable finish to various metals, but there are certain exceptions regarding pure zinc and magnesium. These metals possess chemical properties that make them unsuitable candidates for traditional powder coating processes.
4. Can you recoat over powder coating?
It is possible, but it is also costly. The only real option for touching up powder coating is to apply a layer of paint to the spot, but this is an unsightly fix. It's best to strip and recoat the whole object for a perfect finish.
5. Does powder coating fade in the sun?
Over long periods of time, prolonged exposure to UV rays can cause pigments in powder coating to fade to an extent.
