  ITC-148 Heavy Duty Patching Compound
Surface Preparation
Remove all loose and weakened fiber, bricks, debris, particles, dust and grease from interior walls, door, crown, floor and grooves behind electrical elements. Dampen with a light spay of water and apply ITC-100 HT and let air dry or fire briefly.
Mixing - Dilution
To 1 part ITC-148 add approximately 1/8 part   ITC-100 HT (previously mixed with water per instructions) to achieve desired consistency.
Applying
Apply over ITC-100 HT . Use trowel, spatula or putty knife as best suits the application. Allow to air dry thoroughly before firing.

  ITC-200 EZ Patching Compound
Surface Preparation
Remove all loose and weakened fiber, bricks, debris, particles, dust and grease from interior walls, door, crown, floor and grooves behind electrical elements. Dampen with a light spay of water and apply ITC-100 HT.
Mixing - Dilution
None. Use directly from container over fresh ITC-100 HT. However, if slight thinning is needed use a small amount of water. Diluted ITC-100 may also be used, especially if thinning to a mortar like consistancy.
Applying
Apply over fresh ITC-100 HT . Use trowel, spatula or putty knife as best suits the situation. Allow to air dry thoroughly before firing.

  ITC Product general application information
Compatibility
All ITC products are compatible with each other and with all other refractories as noted. The exception is ITC-213 which is formulated to use on metals and graphite. It can be used as a primer to apply other ITC products over metals.
Temperature Rating
ITC products have a higher temperature rating than any material it is applied over. Application of ITC-100 and ITC-296A increase the surface temperature resistance of the materials they are applied over by reflecting more Infrared energy reducing the temperature of those materials under the coating.
Strength
ITC coatings are harder and stronger than the materials they are applied over. As coatings they can be harder than the substrate but no stronger.
Drying
ITC products air dry but become harder upon firing. For multiple coatings ITC products can be dried by firing briefly.
Cast refractories should be thoroughly dried and then slowly fired to maximum temperature before applying ITC coatings. ITC patching compounds should also be air dried completely prior to initial firing. Drying time for coatings is not long (about 1/2 hour), but varies according to temperature and humidity. Patching compounds take longer according to thickness.
Energy Efficiency
ITC coatings are highly efficient reflectors of Infrared (heat) energy. This efficiency is much higher than other refractory materials and has been proven to reduce fuel costs. Note that this efficiency degrades over time as the surfaces becomes sooted or contaminated with other material.
