Before giving you some insights on how to Cerakote at home on a budget, let us introduce you to the concept and mechanisms of cerakote in short.

What is Cerakote?

Cerakote is the highest performing ceramic-based coating or finishes in the market. You can apply it in metals, polymers, plastics, etc.

What is Cerakote?

Cerakote stands more rigidly than any other coating or finishes because of its extraordinary physical properties and unique formation. It provides exceptional corrosion protection, and resistance from impact damages and harsh chemicals. It also allows you to customize colors from its vibrant color palette options.

Cerakote is mostly used in firearms or guns but you can also use it for your regular-use things like knives, eye wears, wristwatches, etc., and wooden furniture as well.

Should You Cerakote at Home?

For cerakote, you can either go to a professional to do it or you can try it on your own. Both the processes have their pros and cons. If you have the right equipment at hand, cerokoting can be very easy and convenient. But the tough part is getting it done perfectly.

So, before knowing how to cerakote at home on a budget, you should know if you are ready to give it a go. One of the most important things for cerakote is to have the patience for working steadily and tediously. You have to be prepared to invest a lot of time in it. If you can’t think of spending much of your time in it and if you are not a person who can work with patience for a long time, our advice will be – “Don’t go for it”.

Preparations Before Cerakoting

Now that you know that the process is very time-consuming, you don’t want to make silly mistakes and do it all over again, do you? For this, you can schedule your time off work and make sure not to overload yourself with it. Take a nap or walk around for a bit and then start working again with a fresh mind.

Preparations Before Cerakoting

Another very important point for cerakoting at home is knowing space management.

Now that you are aware of the basics, let’s move on to the main supplies needed for the process.


Before starting to cerakote, make sure to list out each and everything needed for the process. Here is a list of the main supplies needed:

  • Cerakote (
  • Measuring and mixing cylinders
  • Rubber Gloves
  • High heat masking tape
  • Acetone
  • AirBrush Gun (Paasche Airbrush HVPL is preferred, with .08mm tip)
  • Air Compressor Pressure Regulator
  • Sandblaster
  • Aluminium oxide

These are the main components. You can easily get at Amazon[S1] . Another useful online platform is Pryme, where you can find any hardware tool.

There are other basic supplies like paper towels, wires, etc which you have to determine according to your need. These supplies are almost always available in our houses or we can buy them anytime from our nearby hardware stores. Now that you have all your supplies, let’s get started with the process.

How to Cerakote Your Glock 42 at Home

Ceratoke can be done on any type of metal. In this article, we are going to give you insights on how to cerakote a Glock 42. The process is pretty much the same for any kind of firearm. Only some ratios and techniques might change due to the size and nature of the object.

Here’s how to do it-

Disassembling the Gun

Before starting, make sure to wear your rubber gloves all the time. You don’t want your hands to be irritated with all the chemicals you’re going to use to cerakote.

The first step of cerakoting is to disassemble your gun. Each and every part of the gun should be evenly done with the coating. That is why only field stripping won’t be working here. So, you might need extra tools to disassemble the gun.

De-greasing the Gun

The second step is very important to cerakote. To de-grease the gun, take a metal container or any other container that would not melt due to pouring acetone. Now take the amount of acetone needed to soak all the gun parts. Soak them for about 30 minutes.

Acetone should not be kept in open spaces for long as it is highly flammable. So, make sure to store it back in a tight container. As an alternative, you can also use brake cleaners instead of acetone for degreasing.

De-greasing the Gun

De-greasing is very much important to clean out the objects perfectly. Greases, surface oils, dust, or dirt are very hazardous as they can result in corrosion, overheating, etc. The excess oil or dirt may also hamper the smoothness of the cerakote.

Abrasive Blasting

Abrasive blasting or sandblasting is necessary to cerakote because it removes unwanted corrosions of uneven coatings and smoothes out the surface. If you are not well acquainted with the process of sandblasting, read out the instructions given with the box or look it up on the internet. It’s certainly not rocket science.

For cerakoting, the company recommendsthat you use Garnet sand or Aluminum oxide #100. For metal parts, sandblast them at approximately 80-90 PSI. For the polymer parts, sandblast them at approximately 30-40 PSI.

After that, look carefully if any oil residue or uneven coating residues are there. If you see any, then you have to repeat the whole process starting from soaking it in acetone. That is why you have to be very careful the first time because the whole process is very time-consuming and needs a lot of patience.

One question may come to your mind that why we need to de-grease the objects as sandblasting does work to ensure there are no oil remains. The answer is: although sandblasting smooths out the hard surface of an object and cleans it, de-greasing ensures no contamination while sandblasting. In a way, it protects the media of sandblasting from excess oil, grease, or dust.

Applying the Cerakote

Now it’s time to apply the cerakote. For your convenience, find a place to hand all the parts of the gun somewhere, using regular metal wires. This will be easier for you to spray the parts without touching them a lot.

Applying the Cerakote

Cerakote is a two-part system and it comes with a color and a catalyst. Make sure to shake the color bottle well before opening it. Cerakote comes with a whole chart( Matte Finish- 24:1, Satin Finish- 18:1, Semi-Gloss- 12:1) to mix the color and the catalyst for different series also estimates how much material you need. You can choose your finish and mix it up according to the ratio chart.

Using a mixing cylinder mix the color and the catalyst well. The mixture stays usable until 2 hours. So, you better use it as soon as you mix it. Now, fill up the container of your airbrush spray and make sure to test it before using it.

The coating cannot be too thin or too thick. For avoiding dry spray, make sure to adjust your spray gun correctly.

  • At first check your air pressure and adjust it accordingly.
  • Now adjust the fan and fluid pattern according to the directions given.
  • Now, spray it in a test metal first to make sure you know how to spray a perfect coating.
  • The pattern of the spray should be even wet 2-3 inches oval.

You can also follow this video, the professionals will tell you how to adjust your spray gun.

Here’s a quick tip: It is okay to start spraying from wherever you like. But try to paint the hard spots, i.e., inside the trigger guard, first. These parts are very detailed and you need to be sure that they are coated nicely.

While spraying the parts, try not to touch it as much as you can, or else you have to start it again from point zero. After coating, leave the parts for a while and start your prep for baking.


Now time for the final step, which is baking the parts for the paint to settle down permanently. This is a very important part of the process.

Different objects have different time duration for baking. Pre-heat your oven for about 15-20 minutes before baking. For the metal parts, place them in the oven and bake them 200 degrees for 2 hours or 300 degrees for an hour.

For the polymer parts, bake them for 150-180 degrees for 2 hours.

Warning! You might not like the smell of the coating. So, if you do it in your oven at home, your entire house will smell like it. In this case, plan and think of how to get rid of the smell or you can make your oven outside of the house using a dehydrator.

Viola! That’s it.

You are all done cerakoting your gun at a home budget.

Now you’re ready to cerakote at home which is much quicker and cheaper than the professionals but you are not sure if it’s correctly done or not. So, you need to satisfice your decision.

Benefits of Cerakoting

Corrosion Protection

Cerakote has multiple mechanical properties to offer. It is not just a coating or paint but it also performs as a great finish for objects like metal, plastic, polymer, and woods.

Some features of cerakoting are-

Corrosion Protection

Cerakote provides extraordinary corrosion protection. It prevents corrosion by creating a barrier between substrate metallic materials and the environment. It prevents damages from corrosive agents like hydrochloric acid, sulfuric acid, sodium hydroxide, etc.


Cerakote has its lubricating elements that let objects run without or a little fluid to function. It tends to attract less dust and dirt particles which allows objects to function optimally.

Chemical and Wear Resistance

Cerakote has an excellent chemical resistance compared to any other coating available in the market. It has been tested with a salt solution to test its resistance capabilities. It can resist heavy chemical compounds like acetone, lacquer thinner, paint stripper, etc.

Resistance to High Temperature

Cerakote is highly resistant to high temperatures. A different version of cerakote has different resistance power. The H series which is usually used in firearms has the capability to resist high temperatures from 500-600 degrees.

There are other versions of cerakote that do not need oven-cure. They are air-cured and they can resist up to 1700 degrees.

Custom look option

Other than providing all the enhanced mechanical supports, cerakote has a wide range of custom ceramic colors over 90 shades. You can choose your customized color according to your taste.

Benefits of Cerakoting

So, whether your firearms need to be protected from corrosion, impact damages, and high temperature or you just want your customized look for it, Cerakote will provide you with everything.
