Concrobium Mold Control is an EPA-registered solution that both eliminates and prevents mold without bleach or other harmful chemicals. The product works as it dries by crushing mold spores at the roots and leaves behind an invisible antimicrobial shield that prevents future mold growth. Use Concrobium Mold Control on virtually any surface for mold clean-up and prevention, disaster restoration, pre-treatment of building materials and musty odor control.
