  •   Smelly but good!
By on
Pros : Works great, gives long life to fiberboard. Relatively inexpensive.
Cons : Smells really bad & toxic when fumes are burned off together in kiln with fiberboard.
Other Thoughts : I tried firing the fiberboard alone in kiln first, then the board coated with mold hardener. Seems to work fine, and greatly cuts down on the overwhelming, combined bad smell.
