Timbor is not labeled to treat mold at all and will not work for this use. Boracare with Moldcare is the only product that we carry for treating mold on bare wood. Boracare with Moldcare will kill the mold spore but you will need to use a product such as Mold-Clean prior to apply Boracare with Moldcare to remove the mold stain.
