Our state-of-the-art facilities, experienced team, and broad service scope has made us the go-to partner for countless clients. One of the questions we often hear from clients is: “Can you powder coat over an existing powder coat?”
Here, we’ll comprehensively answer that question, ensuring manufacturers dealing with large-scale projects can understand the feasibility and implications of layering powder coat finishes.
Understanding Powder Coating
Powder coating is one of the most attractive and effective finishing options available, giving companies a versatile and efficient method of applying durable finishes to a range of services. This dry finishing process uses fine particles of resin and pigment.
These particles are charged electrostatically, and then precisely sprayed onto electrically grounded parts, which are cured under heat. The curing process fuses the powder with the surface, delivering an excellent level of adhesion, and a smooth, consistent, and resilient finish.
Compared to other finishing options such as paint, powder coating delivers superior durability, and exceptional resistance to corrosion, chipping and fading. Powder coating is also an eco-friendly solution, producing minimal waste and volatile organic compounds. This, combined with the versatility offered by a range of powder coat colors and textures, appeals to a range of industries.
In the automotive market, for instance, manufacturers powder coat wheels, frames, and components, ensuring exceptional durability against a range of elements. In the medical landscape, powder coating creates durable, hygienic finishes for medical equipment.
Agricultural companies use powder coating to apply protective layers to machinery and equipment. Musical instruments can be transformed with powder coats to optimize their visual appeal and durability. Even furniture companies use this method to enhance the longevity and aesthetic appeal of metal furniture.
Can You Powder Coat Over Powder Coat?
So, can you apply a second coat of powder on a surface with an existing powder coat? In most cases, the answer is “yes”. However, there are various technical factors that need to be considered.
For instance, when multiple coats are sprayed onto a bare surface, the potential for adhesion is excellent. Powder coating over an existing powder coat requires excellent surface preparation, to ensure the new layer can bond effectively to the other.
Powder coating experts will carefully prepare the surface with meticulous cleaning, sanding, and even chemical treatments, to remove contaminants that could hinder bonding, and promote adhesion.
It’s also worth noting that applying a second coat of powder to a surface will affect the thickness of the component, which can impact fit and function for certain parts. This makes it crucial to apply the second coat with precision, to maintain desired dimensions and characteristics.
Though powder coating over an existing powder coat has challenges to consider, there are advantages to this strategy, such as:
- Enhanced durability: Applying a second coat over an existing powder coat can create an additional layer of protection against various elements, increasing corrosion resistance, and extending the lifespan of the product.
- Improved aesthetics: While powder coating delivers a robust, damage-resistant finish, coats can eventually diminish over time. A fresh coat of powder can rejuvenate the appearance of products, restoring their visual appeal.
- Cost effectiveness: Refurbishing existing parts with a new coat of powder can sometimes be more cost-effective than replacing these parts entirely. This is particularly true if the underlying components of the products are still in good condition.
Preparation and Powder Coating Process
While it is possible to powder coat over an existing coating with the right support, extensive preparation is crucial. At PCS, we take various steps to ensure the secondary coat will deliver the right results for each client, such as:
- Conducting surface assessments: We evaluate the quality and characteristics of the existing powder coat, examining adhesion, thickness, and damage, to determine the best possible course of action when applying a new coating.
- Cleaning: Meticulous cleaning is crucial to remove contaminants that may hinder the bonding and adhesion process. We leverage solvent cleaning and pressure washing strategies, to prepare the surface for a new powder coat.
- Surface abrasion: Methods such as media blasting and sanding can roughen the surface of an existing powder coat, enhancing adhesion and promoting a stronger bond between the new and existing layers, minimizing the risk of peeling.
- Chemical stripping: In cases where applying a second powder coat would be infeasible, we leverage chemical agents to strip the surface, leaving behind a smooth slate ready for a base coat, according to your exact specifications.
- Recoating: Following extensive preparation, we then apply the new powder coat using advanced techniques to ensure excellent results. We then cure the products to bond the coating to the surface and ensure a strong, durable finish.
