We recommend that you contact the manufacturer of the board to ascertain their preferred method of attachment - if they recommend fire cement then yes - it should work as a mortar - it’s heat resistance is higher than that of Skamolex - but bear in mind that extreme heat is required to set the fire cement - until that is done it will remain soft and fluid - and it can shrink with heat - so if possible we would recommend you do an exploratory test to be sure it works in your application.
