Good product used it over duraboard in my forge, very quick shipping

Despite the word Glue in the label title, this really isnt adhesive. It needs thorough mixing, then you brush/squeegee/roll it on porous surfaces. It is an easy water cleanup of tools and hands. It drys to a consistency reminding me of plaster board... easily broken. It is a high temperature coating that should enhance the heat barrier properties of FiberFrax. I applied it to both sides, to double the effectiveness.
