Hello all,
Here is a sticky posting on using Super Isol. It is from the Super Isol supplier. I don't think there is anything new or surprising here, but the information is valuable. This note might be ammended with additional information from the technical folks at the producer.

Super Isol is a very porous product and will suck the moisture out of your mortar. Try slightly dampening the board first, so that the moisture is not as easily absorbed by the board.
The Super Isol should stick to bottom of an existing hearth using skamolex glue. Again, try slightly dampening the board.
If super isol is slightly dampened, it will retain its properties upon dry out. It should not be immersed or soaked in water. Also, it should be dry before being exposed to heat. If the board has to much water and sees high temperature, steam will be created. This steam will have to escape - possibly causing cracks. If to much steam is created, the refractory may "pop". This is true of all refractories, not just the super isol.
