Hi,
I am afraid I haven't been following the ITC threads so this may be
redundant. My husband is rehabing his Raku kiln at school and is
planning on applying ITC but doesn't want to spray it on. He would like to
brush it on and was wondering if anyone has done this - how did it work and
are there any suggestions.
Thanks,
Sally Porter

Hi,
Brush-on is the advice I got personally from the owner of one of the
nation's best known kiln manufacturers. But I don't like the brush on
idea. The manufacturer's objection to spray-on was the air jet's causing
crystoballite (?) fibers getting airborne and getting inhaled sooner or
later.
My ITC application will be a 40 cu ft gas downdraft fiber-walled kiln.
I've been thinking of taping-up a use-once environment suit and spraying
outdoors. But, I find I don't like the idea of spraying either.
I've been thinking about "wallpapering" by dipping and hanging if I
could be sure of a suitable "wallpaper". Maybe nine or ten layers of
clay paper (Nat'l Geo) or perhaps a high-temp glass fiber sheet. The
material would be dipped in the ITC and applied to kiln walls.
I haven't really made-up my mind. Maybe there will be better suggestions
in the list in the next week or so. Maybe some people with a little ITC
left over will experiment and come-up with a superior method. So I guess
I'm waiting.

Dear Sally,
It is always a temptation to brush rather than spray - seems easier, what
with the compressor and all. However, there are a lot of materials that
are heavy in itc and if you try to brush, they will stick in the brush. It
is really not a good idea to brush it. If you have access to a compressor,
all you do is put the sandblaster gun on the hose and put the hose that
comes with the sandblaster into the itc and spray. Once you have the gun
(which is inexpensive), it is easier to spray. You do need to be careful
of overspray which is greater than usual. 296a can be brushed or even
rolled with a foam roller. It is very creamy. This is not the case with
100. When you do fiber, you need to turn the pressure down. 80 lbs will
rip the fiber apart.
