Frequently Asked Questions

Powder coating is a dry finishing process where a finely ground powder is electrostatically applied to a metal surface and then cured in an oven at high temperature. This creates a smooth, durable, and protective finish that is far more resistant to chipping, scratching, and fading than traditional paint.

Powder coating provides a strong, long-lasting finish that offers excellent resistance to corrosion, weather, UV exposure, and everyday wear. It also provides a wide range of colours and textures and is considered an environmentally friendly coating process because it produces minimal waste and does not rely on solvents.

Most metal products can be powder coated, including:

• Aluminium

• Mild steel

• Galvanised steel

• Stainless steel

• Cast iron and other metal components

The item must be able to withstand the curing temperatures used in the powder coating oven.

Proper preparation is essential for achieving a high-quality finish. Items are typically cleaned, degreased, and may undergo blasting or chemical pretreatment to remove rust, oils, or previous coatings. This ensures the powder coating adheres properly and performs well over time.

Turnaround times depend on the size and complexity of the job, but most powder coating projects are completed within a few days. Larger or specialised jobs may take longer depending on preparation and colour requirements.

Yes, but the existing paint or coating usually needs to be removed first through blasting or chemical stripping. This ensures the new powder coating bonds properly to the metal surface.

Yes. Powder coating is highly resistant to UV exposure, corrosion, and harsh weather conditions, making it ideal for outdoor applications such as fencing, gates, architectural aluminium, and outdoor furniture.

Whether material selected is fit for purpose and the environment is especially important though, so don’t hesitate to reach out to discuss.

Before coating, customers should remove any materials that may melt in the oven such as rubber, plastic parts, wiring, seals, or bearings. Any areas that should not be coated should also be clearly identified before the job begins.

Regular cleaning with mild non-alkaline soap and water will help maintain the appearance and prevent dirt or contaminants from building up. Avoid harsh chemicals or abrasive cleaners.

Cleaning your product regularly and in line with powder suppliers’ recommendations depending on the environment will assist in making your product last. Please refer to attached Care and Maintenance information.

Yes. Omega Prestige Coaters specialises in powder coating aluminium products commonly used in architectural and construction applications. Our coating processes are designed to provide strong adhesion, corrosion resistance, and long-lasting finishes suitable for both indoor and outdoor.

Our powder suppliers strongly recommend Black or Blue steel to be sandblasted prior to powder coating primarily to ensure proper adhesion, surface cleanliness, and long-term durability.

Without sandblasting, powder coating on black or blue steel can result in:

• Poor adhesion > peeling or flaking over time

• Uneven finish > blotches or thin spots

• Reduced corrosion resistance > rust forming under the coating

Think of sandblasting as prepping the canvas: if the surface isn’t properly prepared, the final coating will fail no matter how good the powder is.
