applying itc on a kiln with fiber already installed

Hey all! Again, I have been delving into archiveland,
and read that ITC should not be applied on loose
vertical fiber, as it can add weight and cause it to
pull away. I just got an Olympic downdraft kiln, fiber
and all, and am wondering if there is any acceptable
way to apply ITC without removing the fiber? I realize
it should be thoroughly flattened, and I can try, but
is it worth the hassle? It is a brand spankin' new
kiln, and I feel really uncomfortable about removing
the fiber to spray it, but I also know that ITC really
needs to be used to it's specifications. I plan to
also contact the company, but thought that if any of
you had personally tackled this issue, it could
certainly help. Thank you! Jules
P.M.S. The quality of the fiber seems to be good, nice
and tight.

Don't remove the fiber. I sprayed my Bailey fiber Kiln with water first.
Then
sprayed ITC.
It hasn't pulled away. You just spray a light coating of ITC. Call ITC and
talk
with Feriz.

Spraying ITC on installed fiber is perfectly allright.

Be sure you wet the fiber well before using the ITC...get it good and wet,
this allows the ITC to penetrate the surface of the fiber, plus it cuts down
on loose fiber blowing around.

Thin the ITC 1-1 with water...mix the ITC thoroughly in the original
container first, then mix with water. Spray on two THIN coats, as a thick
coat might flake off.

Spraying is definitely a 2 person job...one to spray, and the other to stir,
as the ITC will settle faster than you can say "crap, the gun's clogged
again"! Keep all the grit up in suspension.

DO NOT spray contact surfaces...where the door seals to the fiber...you will
break the ITC surface and it will fail anyway, so save your money.

While it is not recommended you can spray old fiber too, soak it well, and
using a block of wood beat the surface of the fiber to loosen it where it
has tightened up...don't do this dry, ever...when the surface of the fiber
is loose to the touch, spray as normal...

PS...Mask, goggles,long sleeved shirt, and hair protection are all highly
recommended for this procedure!
