Mold Prevention Non-Toxic Spray

Mold’s Greatest Enemy TM

For All Indoor & Outdoor Surfaces

Unique Benefits

Significantly Outlasts Competitors

Bleach doesn’t kill mold roots embedded in porous surfaces. And other mold products get rinsed away when first exposed to moisture. Our Mold Prevention Spray eliminates roots and spores while lasting through hundreds of wet-dry cycles. You’ll save time, cost and hassle.

BioDoorTM Dual Layer Formula

Our innovative formula uses a high-tech, microscopic polymer to bind a proprietary blend of EPA registered biocides to any indoor or outdoor surface.

Rest assured that you’ll get invisible protection against mold, mildew, germs and musty odors for far longer than bleach or any other anti-mold product.

Non-Toxic plus No Fumes (zero VOCs)

Certified non-toxic by the leading toxicology expert at the Duke University School of Medicine.

No bleach. No triclosan. No risky chemicals. Zero VOCs – no harmful fumes. So no need for HAZMAT gear when applying. Safe for people, pets, plants and the environment.
