I'm in the process of re-lining my forge. I have completed installing new insu-wool and a satanite layer. In the past I have stopped there but this time I'm am planning on applying some ITC to it.

Since I've not used the ITC before I'd appreciate any thoughts on how best to finish the re-lining of it.

Thanks,

Gary

I put a pint into a quart mason jar, add 8 ozs of water, close and shake to mix. Then I let it sit for a couple of hours and mix it again.

I spray the surface to be coated lightly with water. Next I use a stiff artist's paint brush and use the slurry of ITC in the jar to paint the surface. This requires patience and continous working of the surface with a wet brush until a heavy slurry is formed. The advantage of this method is that no material is wasted in mixing in a second container.

I have stored the left over mix in the jar placed into a zip lock bag and used it a couple of days later finishing another project that I was doing. (Spread it over some pavers to create a work surface)

I have my forge up & running again. Not only is it now getting much hotter than a week ago with the old insulation but is now getting hotter than it was when new. I'm not sure if this is due to the ITC layer or to doubling the insu-wool on the top but it now will get up to 2450 degrees which is the highest that I have ever gotten it.

ITC is good stuff! I've been using it for a few years. The only thing I would add to what's been said is to mix it NO THICKER then latex paint....and a LIGHT coat is all you need. Anthing more is just wasting an expensive product, for no gain. First time I used it I wasted a bunch of it, but over time and with experimentation, I've found that a single light coat does just as much as using the whole container. I reline my welding forge at least 4x per year, and a 1/2 gallon container of ITC will generally last me about 2 years.

Hey Ed! I see that you reline your forge x4’s a year! Wow. Well, maybe you can help me please? I was gifted a new-to-me Devils Forge. It’s a two burner with one door model. I was told it has a few burns left in it and have fired it up once. With that said I just want to knock out the relining now. Not sure where to start because everything on YouTube I find seem to be new build with materials provided. Seems like I need to get new wool (but from who? Brand? Thinkness? More than one layer?), satanite to coat (again from where? Brand? etc), and an optional second coat of another product?

I’m a new maker and have been doing stock removal as I’ve been learning to forge- well now I have one and needs a tune up. Can you help? Any info/direction/recommendation is appreciated. Thanks!
