Rigidizer for Ceramic Fiber Coating, 2300F Rated, Fireproof Insulation Surface Coating for Ceramic Fiber Blanket Boards Wool – 16 Oz Rigidizer

This material is very much akin to a milk consistency, though clear. In order to make sure you have adequate coverage buy more than 2 bottles. I bought 4. They say it covers well but for my own peace of mind I would prefer to apply a fairly generous coating for permeation of the fibrous material. Will take pictures and post an updated review after the first firing of the kiln. I have read suggestions such as applying a dye to the liquid to make sure you know what you have covered. I recommend that. As it is clear and once applied to ceramic wool fiber, you can't tell what has and has not been covered.

Slapped it in a spray bottle with a 1:1 ratio of water. Sprayed liberally and waiting 2 days for it to dry. Took me using 13psi down to maybe 7psi in my forge to reach temps while keeping the blanket together preventing me from breathing in fibers. Definitely a great product!

Consistently reliable product. Works exactly as expected.

Works really well at Harding. Definitely wear a face mask and gloves

Works great!

This product worked great to hardening my blanket for my forge ... one thing I would say is make sure you don't do half and half it will take forever for it to dry I placed my forge in the oven at 280 for about 2 hrs helped alot . I would do 3 parts solution to 1 part water it will go faster but it makes it harder to come out the spray bottle .

Works grate

I used this for 2 burner Vevor Propane forge. Worked great on hardening the fibers so I could coat with refactory.

Easy to mix. I’d certainly recommend using a hand spray bottle to apply it rather than a brush. It seems to rigidise my thermal kiln blanket well and is economical.

Works great perfect for prep on isolation and activities fast and strong

I think, it's a bit expensive, but it clearly does what is promised.

Did what it said on the Tin. Easy to apply.

Worked well for setting up a small forge. Stands up to repeated uses.
