Update; I made work, kinda. As the refractory i used last time didnt work, i was gonna replace it.That time it wasnt bonding to the wrap at ALL. I found out that after exposing the wool to proper heat, the liquid absorbed much better. I have no idea why. Not sure if i soaked it too much this time, if that matters at all. I'm doing another spraydown later of the remaining white patches. Mixed the rigidizer thicker and added a little bit of soap. The sides of the wool absorbed water just fine so i think it has been treated somehow on the front side. Also got in contact with FyreWrap and they told me that its usually secured by pinning the material with clips or pre-welded pins, and not rigidized with colloidal silica. . Some kind of putty was normally used to bind the fibers on the surface of the wool. Tinkertim you are correct, its used for wrapping piping industrially.

The beading happens with both the rigidizer and plain water. I remember reading from frosty that you could use West systems 406, so thats what i used. Not sure if its Hydrophobic or hydrophillic, im assuming hydrophilic. It mixed out with water just fine? I am going to try and rough up the surface of the wool and use some soap in the mix, see if that helps. It was the only insulation that i had "easily" acessible up here in the Norway, probably not the most ideal though. . I'm struggling to find an alternative to KOL, not sure what to do.

I will try adding soap to the mix and see if that works, clever. Sent Fyrewrap an email. I just thought someone else here had experienced the same thing. Even after watering it down with a garden hose it still won't absorb well. Also; Do you light the forge after applying the ridgidizer?

Thomaspowers, Havent asked them. Good point. Writing them an email right now. Didn't think they could provide me with an answer regarding this, but we'll see.

Hello all. Have been stalking this forum for a while, finally made an account. Couldn't find any threads on here about this, but delete this if its been answered before. When im buttering the ceramic wool for ridgidizing, it wont absorb at all. The water just pools up as little droplets on the surface of the wool. It's called "Fyrewrap" I believe, used as insulation on industrial pipes. It can apparently handle ~1260C (2300 freedom-units). On one side it has some sort of metal foil to keep it from fraying, easily comes off. Is it possible that i used too little colloidal silica in the mix? Any tips? And BTW, i have a couple gas-forge questions unrelated to ridgidizing and would appreciate if i can ask someone on PM.
