WHAT IS MIL THICKNESS? HOW DOES IT AFFECT CERAKOTE?

A "mil" is a unique unit of measurement used to determine coating thickness. Special instruments called Mil or Coating Thickness Gauges are used to measure mil thickness. How thick is one mil? An average credit card is 30 mils thick. One mil is 1/30th of the thickness of a credit card!

Note: A mil is 1/1000th of an inch. A mil is NOT equal to 1 mm.

The mil thickness of a coating not only affects the appearance of Cerakote coatings, it can also affect the performance and protective qualities. A coating with a mil thickness that is too thin may have less than 100% coverage leaving the substrate vulnerable to corrosion. A coating that is too thick can have lessened overall durability. It is important to always strive for the correct mil thickness when applying Cerakote.

We highly recommend using the Cerakote mil Thickness Gauge to check for proper coverage of parts sprayed. The gauge we offer works on ferrous metals such as cast iron, carbon, and stainless steel, as well as non-ferrous metals, like aluminum.
