Powder coating starter kits have made it easier than ever for small businesses and workshops to achieve durable, high-quality finishes.
However, while these kits are designed for simplicity, a few common mistakes can affect the coating quality, finish, and durability of your projects.

Let’s explore the five key mistakes to avoid — and how to get the best results every time.

1. Skipping Surface Preparation

The most common — and costly — mistake is applying powder to an unprepared surface.
Even a trace of oil, rust, or dust can prevent the powder from adhering properly.
Always clean, degrease, and pre-treat your parts before coating.
For metal surfaces, using a sandblaster or chemical cleaner ensures better bonding and a smoother finish.

Pro Tip: A clean surface equals a durable coat. Never rush this step.

2. Incorrect Grounding

Proper grounding is critical to ensure even powder attraction and minimize overspray.
Many beginners overlook grounding, leading to patchy coverage or wasted powder.
Make sure the part and the gun are both grounded before spraying.

Pro Tip: A strong electrical connection ensures consistent coating and reduces material waste.

3. Applying Too Much Powder

It’s tempting to spray more powder for “better” coverage — but that often leads to runs, clumps, or uneven texture after curing.
Powder coating relies on electrostatic balance; excess powder can disrupt it and cause imperfections.

Pro Tip: Spray in thin, even layers and build up coverage gradually.

4. Ignoring Curing Temperature and Time

Curing is where your powder coating truly sets.
If the temperature or timing is off, the coating can under-cure (leading to weak adhesion) or over-cure (causing color change or brittleness).
Always follow the manufacturer’s guidelines and use a reliable curing oven or heat source.

Pro Tip: Use a temperature gun to monitor and maintain consistent curing conditions.

5. Using Low-Quality Equipment

Not all powder coating guns or starter kits deliver the same results.
Cheap or poorly designed guns often cause inconsistent spray patterns, uneven powder flow, or higher waste.
Investing in a precision-engineered system ensures smooth operation, better control, and long-term cost savings.

Pro Tip: Choose trusted equipment — like IMIS Powder Coating Guns — built for efficiency, consistency, and durability.
