Cerakoting a gun barrel offers a durable and aesthetically pleasing finish. This process protects your barrel from the elements, reduces wear and tear, and allows for customization. This guide provides a step-by-step walkthrough on how to Cerakote a barrel safely and effectively.

Preparing Your Barrel for Cerakote

Before you begin the Cerakote process, proper preparation is crucial for a successful outcome. This involves cleaning, prepping and masking.

1. Thorough Cleaning

Degreasing: Begin by thoroughly degreasing the barrel. Use a high-quality gun cleaning solvent like Hoppe's No. 9 or a similar product. Remove all oil, grease, and dirt. Pay close attention to the rifling. A clean barrel is essential for optimal adhesion.
Scrubbing: Use a bore brush appropriate for your barrel's caliber to scrub the entire length. Repeat this process until you achieve a spotless finish.
Drying: Allow the barrel to air dry completely. Residual moisture can negatively impact the Cerakote application.

2. Surface Preparation

Media Blasting: This crucial step creates a surface profile suitable for Cerakote adhesion. Media blasting with aluminum oxide or glass beads creates a slightly rough surface, improving the bond. Use appropriate safety gear (respirator and eye protection). Consider using a dedicated media blasting cabinet for better control and containment of the media.
Alternative: Scotchbrite Pad: If you lack media blasting equipment, a fine-grit Scotchbrite pad can be used. This method is less effective, requiring more thorough cleaning afterward and possibly compromising the final finish's durability.

3. Masking

Protect Threads: Thoroughly mask any threads, or areas that you do not want Cerakoted. Use high-quality painter's tape and ensure a tight seal to prevent overspray. A compromised seal can lead to Cerakote in unintended areas.
Critical Areas: Pay close attention to the chamber and muzzle. These areas require precise masking to prevent Cerakote buildup.

Applying the Cerakote

Once the barrel is prepared, you can apply the Cerakote. This section covers the process of applying the Cerakote.

1. Mixing the Cerakote

Follow Instructions: Carefully follow the manufacturer's instructions regarding mixing ratios. Using the wrong ratio can ruin the finish. Thoroughly mix the Cerakote to ensure uniform consistency.
Proper Equipment: Use a clean, dedicated container and stirring utensil to avoid contamination. Avoid introducing air bubbles during the mixing process.

2. Application Methods

Spraying: The most common method is using an airbrush. This allows for even coating and precise application. If using an airbrush, practice on scrap metal first to get a feel for the spray pattern and pressure.
Brushing: While less common for barrels, some users successfully brush on Cerakote, especially in hard-to-reach areas. This requires great care to achieve an even coat.

3. Even Coating

Multiple Thin Coats: Apply multiple thin coats rather than one thick coat. Allow each coat to dry according to the manufacturer's instructions before applying the next. This helps prevent runs, sags, and an uneven finish.
Wet-on-Wet: Some Cerakote products allow for wet-on-wet application, where successive coats are applied before the previous one dries completely. Check your specific product's instructions.

Curing the Cerakote

The curing process is critical for achieving a durable and long-lasting finish. Pay close attention to this critical step.

1. Curing Temperature and Time

Oven Curing: The most common method is curing in an oven at a specific temperature and duration. Refer to the Cerakote manufacturer's instructions for precise temperature and time requirements. Incorrect curing temperatures can damage the finish.
Safety Precautions: Never cure Cerakote in a kitchen oven. Use a dedicated curing oven to avoid contaminating food and appliances with the fumes.

2. Post-Cure Inspection

After the curing process, carefully inspect the barrel for any imperfections. Lightly sand and re-coat any minor imperfections if needed. Once you are happy with the finish, you are ready to reassemble your firearm.

Conclusion

Cerakoting a gun barrel offers a superior finish that enhances both durability and aesthetics. By following these steps carefully, and using the proper equipment and safety precautions, you can achieve professional-looking results at home. Remember that practice makes perfect; consider practicing on scrap metal before tackling your firearm barrel. Always prioritize safety and refer to the manufacturer's instructions for your specific Cerakote product.
