It’s a favorite among gun owners, competitive shooters, and manufacturers for both the protection and customization options it provides.

A key aspect of Cerakote’s effectiveness lies in its chemical composition. The coating is formulated with a blend of ceramic particles and a binding agent that, when properly applied and cured, create an incredibly hard and resilient surface. This resistance is vital for firearms, which are subjected to harsh conditions, including high temperatures, friction, and exposure to cleaning solvents.

The benefits of Cerakote extend far beyond mere protection. The coating is available in a vast array of colors and finishes, from matte to gloss, enabling unparalleled customization of firearms. Whether aiming for a tactical, utilitarian look or a vibrant, personalized design, Cerakote offers the versatility to bring any vision to life. This is what truly sets it apart and makes it an essential skill for any serious gunsmith.

To successfully apply Cerakote, a well-equipped workspace is essential. The following list outlines the critical tools and materials needed:

Cerakote Coating: This is the foundation of the entire process. Choose your desired colors and finish types, considering the specific application and the desired aesthetic. Ensure that you purchase the correct Cerakote series for the material you intend to coat (e.g., H-Series for most metals).
Airbrush or Spray Gun: A quality airbrush or spray gun is crucial for even and controlled application. An airbrush allows for fine detail work and small parts coating, while a spray gun is better suited for larger surfaces. Proper maintenance of the chosen tool is crucial for consistent results.
Air Compressor: A reliable air compressor is necessary to supply a consistent flow of air to the airbrush or spray gun. Make sure the compressor is capable of maintaining the required pressure (typically between 20-30 PSI).
Abrasive Blasting Cabinet and Media: A blasting cabinet is used to prepare the metal surface before applying Cerakote. Choose the appropriate media for the material (e.g., aluminum oxide for steel and iron, glass beads for aluminum). This process creates a surface profile that enhances adhesion.
Cleaning Supplies: Thorough cleaning is essential for optimal adhesion. Use a degreaser, such as Cerakote’s own recommended products, to remove any oils or contaminants. Lint-free cloths or wipes are recommended.
Surface Preparation Materials: This includes items like masking tape (high-temperature tape is best), masking paper, and plugs for plugging holes and threads.
Curing Oven: Cerakote requires curing at a specific temperature to achieve its full protective properties. A dedicated oven is crucial for this process. Make sure the oven is capable of maintaining a consistent temperature and is large enough to accommodate the firearm parts.
Safety Gear: Always prioritize safety. Required gear includes a respirator with appropriate filters (organic vapor and particulate), safety glasses, nitrile gloves, and appropriate clothing. Proper ventilation is also critical.
Mixing Cups and Stir Sticks: Use disposable, clean containers for mixing the Cerakote coating.
Protective Work Surface: A clean work surface to prepare and dry the pieces.

The Step-by-Step Guide to Cerakoting

Applying Cerakote is a detailed process that demands precision and attention. Following these steps meticulously will help ensure a high-quality finish:

Preparation: Disassembly and Cleaning

Completely disassemble the firearm.
Thoroughly clean all parts with a degreaser, removing any oils, grease, or contaminants. Pay close attention to all crevices and internal surfaces.

Surface Preparation: Abrasive Blasting

Place the parts inside the abrasive blasting cabinet.
Using the appropriate abrasive media, blast the metal surfaces. This creates a textured surface that provides an excellent bond for the Cerakote. Ensure even coverage.
Remove any residual media from the parts after blasting.

Surface Preparation: Final Cleaning

After blasting, clean the parts again with a degreaser.
Handle the parts with clean gloves to prevent contamination from skin oils.
Thorough drying of the components is critical before the next step.

Masking and Plugging

Use masking tape, masking paper, and plugs to cover areas where Cerakote is not desired (e.g., internal threads, trigger components).
Use high-temperature tape to prevent the tape from melting in the oven.

Mixing the Cerakote

Carefully mix the Cerakote coating according to the manufacturer’s instructions. Pay close attention to the recommended ratios and mixing techniques.
Strain the mixture to remove any particles that could clog the airbrush or spray gun.

Applying the Cerakote

Set up your airbrush or spray gun.
Apply the Cerakote in even, thin coats. Overlap each pass by about 50% to ensure uniform coverage. Avoid applying the coating too thickly, which can lead to runs and drips.
Allow each coat to flash off (dry) according to the manufacturer’s instructions. Typically, this is a matter of minutes.
Multiple thin coats are preferable to a single thick coat.

Curing the Cerakote

Place the parts in the curing oven, ensuring they are positioned in a way that allows for even heat distribution.
Follow the manufacturer’s recommended curing schedule, paying close attention to the temperature and duration.
Once the curing cycle is complete, let the parts cool completely before handling.
