For their extensive knowledge of architectural processes, powder coating specialists are responsible for ensuring the smooth execution of multiple tasks. However, in the case of specifying a powder coating, a failure to select the appropriate coating for a particular application can result in expensive mistakes and subpar finishes. This can not only disappoint the client but also damage the specifier’s reputation.
Powder coating products vary in quality, as they come in different grades determined by the technology and chemical formulation employed. Typically, each powder coat technology offered by a manufacturer is tailored to attain specific end-use features such as resistance to chemicals, UV, impact, abrasion, and non-slip properties.
A few typical mistakes can arise when specifying powder coating, but these can be easily prevented with a bit of thoughtful preparation before the pretreatment of the workpieces:
1. Not familiar with related industry standards
Powder coating mistake No.1. Some specifiers mistakenly assume that all powder coat finishes will deliver peak performance, regardless of the technology used by the manufacturer.
There is a prevalent misconception that Australian Standard AS3715 is adequate for exterior performance on specific project types, even when it may not be the case. Merely specifying powder coating to AS3715 can result in an unsuitable product or inappropriate finish that may fade or deteriorate, and may not be warranted for certain end-use applications. This is especially evident in commercial, marine uses, and non-aluminium substrates.
How to Avoid It:
To guarantee that the specified powder coating and application process meet or surpass industry standards, it’s crucial to be unequivocal about the desired outcome.
The American Architectural Manufacturers Association (AAMA) is a globally recognized voluntary performance standard for architectural finishes that promotes superior performance standards. It recommends a worldwide standard of 2603 (equivalent to AS3715) for residential domestic projects, and 2604 or 2605 for multi-density and commercial projects.
Although the AS3715 standard describes the performance of architectural powder coat finishes for Australian conditions, it’s important to note that this performance criterion is best suited only for domestic residential applications. This can impact the perceived warranty. Most reputable brands of architectural powder coat finishes provide warranty performance that conforms to a variety of standards and offers varying levels of exterior performance.
Numerous suppliers offer architectural grade powder coat systems that meet or surpass these standards. Additionally, most reliable manufacturers have a network of accredited applicators, and utilizing these applicators can guarantee that your projects achieve and maintain an ideal finish.
2. Not sure about the application scope of powder coating
Powder coating mistake No.2. Several specifiers are unaware that powder coating can be utilized on steel and hot-dip galvanized steel (HDG), assuming it’s solely suitable for aluminum. Nonetheless, powder coatings can be applied to steel and HDG, enabling you to sustain color consistency across various components of your project.
How to Avoid It:
Inquiring about your selected powder coating’s performance capabilities is essential. You may be amazed to discover that certain brands offer high-performance warranties even on steel and HDG.
3. Selecting the wrong coating products
Powder coating mistake No.3. Various powder coating products and brands will yield diverse results.
Selecting the wrong product systems could result in expensive recoating due to cracking, peeling, and/or fading. For example, some powder coat systems are purposely engineered to endure graffiti, marine environments, or chemical environments, while others are formulated to resist damage from light or UV exposure. Certain coatings are also intended to achieve a high-gloss, textured, or flat matt finish.
How to Avoid It:
Coordinating with your supplier to determine the optimal coating for the project at hand is crucial. The appropriate coating will be contingent on your specific requirements, so it’s important to discover the appropriate brand and product systems to guarantee the best outcomes.
4. Thought that all powder coating products can be used outdoors
Powder coating mistake No.4. Some powder coating formulations are more appropriate for indoor or outdoor use, and specifying interior grade products for an external project can have a significant impact.
If a formulation is intended for indoor use, application for outdoor furniture or other things may lack resistance to UV radiation damage or weather events. As a result, the coating may deteriorate, exposing the underlying substrate/component to the elements, resulting in more significant issues.
How to Avoid It:
Specifying whether the product will be utilized indoors or outdoors is critical. For projects that necessitate both internal and external coatings, be precise and explicit about which standards and warranties are relevant.
5. Care more about color rather than performance
Powder coating mistake No.5. When colour is crucial to a project, it may be tempting to prioritize this requirement above all others.
Prioritizing colour over product performance can be a costly mistake, as it may result in significant issues. Additionally, comprehending the end-use application of a powder finish product is critical, as exposure to airborne pollutants like sea salts or chemical atmospheres is critical to long-term coating performance.
How to Avoid It:
It’s important to confirm that the product’s performance, not just its colour, will be long-lasting.
To ensure long-lasting performance, it is crucial to determine which industry standard is most suitable for the specific exterior conditions of your project. Simply specifying a colour that is not designed or formulated to withstand the project’s weathering and environmental conditions may result in premature fading and chalking.
The benefits of powder coating can be greatly diminished by a single mistake, which is why there is such a wide range in the quality of powder coated products. Therefore, meticulous attention to detail is essential during the application process.
