Mold inhibitor in Hardiebacker, DensArmor Plus, Wonderboard, and Purple Board (XP)?
All of these products… Hardiebacker, DensArmor Plus, Wonderboard, and Gold Bond XP (Purple Board) indicate that they inhibit mold growth, but I do not see any specific mold inhibitor listed on the SDS sheet. Does anyone know what the mold inhibitor is?
