Basic question. When using rigidiser (colloidal silicon) on ceramic fiber, how much is enough?

I am not planning on using any other coatings at this time since I do not forge and will only be using my forge for heat treating. ITC100 would be nice, but since this is my first go at making a forge I am far from convinced that the extra expense is justified just yet.

The forge has internal of about 5"dia x 13" and I have used about half a pint of rigidiser so far, applied with a brush. I have the rest of the pint and wondered if 1/2 was enough, or whether I should splosh on the rest.

Any suggestion? Including the thread out there, which I have yet to find, but which is bound to have answered this already :rolleyes:

Thanks.

I'd go with just a small amount, as you don't want to soak the fiber all the way through. Kind of defeats the fibers purpose of insulation.
Most builds I've seen use some sort of troweled on or thinned slightly and brushed on, cement or bubble alumina.
The ITC-100 will cut the fuel bill, although a bit pricey. Good for fireplace coating, too, as the radiated heat will be greater.
All the experts are off at Blade...
Maybe they'll check in and enlighten us.
 
I just put it in a container and apply it with a paint brush. No need to soak the wool, really, just coat the outside.

Thanks for the advice:) I ended up using a paint brush to apply the rigidiser, it worked a lot better than trying to spay it on (domestic spray bottle lasted about 4 squirts:grumpy: )

The forge is kind of finished, other than the burner hole through the insulation, which is being a royal PITA to set up right. If I can get the flare in the insulation set so that the flare on my Shorty Burner doesn't glow, I might go to the expense of ITC100.

Thanks again :D
