At D&K Powder Coating, we know that choosing a powder coating provider can be overwhelming. That's why we've put together a list of frequently asked questions to help guide you through the process. Below, you'll find answers to some of the most common questions our customers ask. If you can't find the answer you're looking for, please don't hesitate to contact us.

  • What is Powder Coating?
    Powder coating finishes are applied electrostatically and cured under heat so it acts like an armor. It is more resistant to impact, moisture, corrosion, chemicals and ultraviolet light. It is less susceptible to scratches, abrasions, chipping and general wear and tear and it creates a durable finish that is substantially stronger than conventional paint. Powder coating is a solvent-free, environmentally friendly finish that virtually eliminates air and water pollution because it releases no VOCs ( volatile organic compounds ) into the atmosphere, which makes it safer for applicators and the environment.
  • Is powder coating better than liquid paint?
    Yes, powder coating is baked onto the metal part, forming a thicker layer of protection that is stronger and more weather-resistant, minimizing scratching, peeling and fading.
  • What powder colors do you offer?
    There are several hundred standard colors and textures to choose from, or we can have your color matched. For faster turnaround and more competitive pricing, we have many stock colors to choose from.
  • What is the largest size that can be powder coated?
    We can accommodate any size part up to 16' wide x 12' high x 52' long.
  • What's the largest size that can be blasted?
    Our blasting capabilities for grit blasting are 20′ x 14′ x 51′ . We also have an aluminum oxide room 15′ x 12′ x 28′.
  • What is the smallest production run you'll contract?
    $500 minimum
  • Does my part need to be blasted before powder coating?
    Many parts that come to us do need blasting before being coated. Our blasting services remove any surface residues before coating to ensure an even application and provide microscopic scoring into the surface of your product to promote a stronger bond with your primer or powder coat. However, if a part is new, clean, and has no mill ⁄ laser scale or corrosion of any kind, we can coat it without any blasting.
  • What is powder coating pretreatment?
    Powder coating pretreatment thoroughly cleans the surfaces of your parts to remove any dust or particles that may interfere with your finish. We use a seven-stage system that cleans your parts and helps improve the bond with your finish.
  • Do you prime before powder coating?
    Whether you have products made from aluminum or steel, priming will help extend the life of your product and coating. Aluminum provides natural resistance to rust and corrosion. Still, if it comes into contact with another metal part or product with conflicting properties, your products can suffer rapid deterioration due to corrosion. Steel and other metals are cost-effective and easy to work with, but when exposed to the elements, they will start to rust fast, destroying your product and the coating. Our experts know which primers to match with your metals to ensure you gain the maximum advantage, and we only use products from leading manufacturers.
  • What are your pick up and receiving hours?
    Monday - Thursday: 7:00 am - 4:00 pm Friday: 7:00 am - 3:30 pm
  • How do I get a quote on my parts?
    The best way is to bring your part to us for evaluation. However, if that is not feasible, you may use our online form or contact us at (507) 388-4100.
  • Can you powder coat wood or plastic?
    We specialize in coating metals. Steel, aluminum, cast iron, cast aluminum, zinc and stainless steel are the most common. We do not have the capability to powder coat wood or plastic.
  • Will powder coating fail if chipped or scratched?
    While any scratch to bare metal is not desirable and does compromise the surface, our research has shown that when parts are processed through our 7 stage pre-treatment, the applied conversion coating greatly limits the creep of the scratch.
  • How long does powder coating last?
    Powder coating can last for decades with the right surface preparation, application and powder. Before you coat any metal part, you will want to speak to an expert to ensure you apply a powder capable of withstanding the conditions you are going to put your products through. From start to finish, we use trusted products and processes to ensure quality work you can depend on for years.
  • How is cost calculated?
    Cost is calculated by a variety of factors such as surface area, weight, complexity to hang and handle, the preparation process, and the finish chosen. D&K Powder Coating provides customers with fair and competitive pricing.
