There is not a pre-treatment that is required when applying Boracare with Mold-Care. You may use Mold Clean to removed any existing stains from mold or to brighten the wood before applying Boracare. You should also be sure that the wood is free from dust or other debris before apply Boracare with Mold-Care.
