Pottery, ceramics, artwork, and glassware are all created through a high heat process that often involves a kiln. A kiln is a heating chamber used to transform materials at high temperatures. The earliest known kilns date back to 6,000 BCE and were capable of firing up to 900 degrees Celsius. Today, the average kiln can fire up to 1,800 to 2,400 degrees Fahrenheit. A kiln hardens ceramic bodies using a process invented thousands of years ago. Ceramic is incredibly heat resistant and can withstand temperatures of 2,000 degrees Celsius.

What Is ITC 100 Ceramic Coating?

ITC ceramic coating is a versatile high-temperature coating for the inside of kilns and elements. Kiln elements typically last up to 100 firings but it’s best to change a kiln element when the element has increased resistance by 9%. ITC 100 ceramic coating is made for kilns with insulating brick, lightweight castable, or fiber interiors. With this coating, you can save fuel, and protect your kiln. ITC high-temperature ceramic coating can withstand up to 5,000 degrees Fahrenheit and protects against wear and corrosion.


There are five types of ITC ceramic coating including ITC 148, ITC 100HT ceramic coating, ITC 213 ceramic coating for metals, ITC 296A ceramic top coating, and ITC 200 EZ ceramic repair. ITC 100 saves energy, increases production, and protects refractory equipment as well as ceramic fiber insulation. It offers outstanding heat resistance, reflection, and insulation that decrease energy costs and makes heat processes more efficient.

The ITC 100 Application Process

Learning how to apply ITC 100 is an easy feat. From the ITC instruction page to online videos, there are many ways to become familiar with this process before you try it. Although the method is generally the same for ceramic coatings, here’s a simplified ITC 100 application instructions.

1. 1. Remove all loose and weakened fiber, bricks, debris, dust and grease from interior walls, door, crown, floor and grooves behind electrical elements.
2. 2. Immediately before applying ITC-100 HT, spray surface lightly with water.
3. 3. Combine 1 part ITC-100 HT with 1/2 part water and mix well. Let sit for a few hours or overnight then mixing again to smooth mixture.
4. 4. Spray large surfaces using a texture paint system of the type used for ceilings. Agitate as necessary to prevent settling.
5. 5. Brush small areas. When brushing onto ceramic fiber two coats are usually needed. The first coat may be fired briefly prior to the second coat.


Kilns and other refractory equipment hot and dangerous. Understanding the ITC 100 application can keep you safe and help achieve better results. If you are familiar with cleaning and maintaining kilns and elements, then worry less about the ITC 100 process and more about its benefits to your current equipment. Use ITC high temp coating to improve your overall heating processes and increase the life of your equipment.
