I sprayed Concrobium Mold Control on the surface and let it dry, but the mold is still there. Why?
Concrobium Mold Control contains no bleach or whiteners. Once you have sprayed the solution on the moldy surface and allowed it to dry, the mold has been encapsulated and eliminated – in other words, your mold problem has been eradicated. If staining or residue remains, scrub with a Concrobium-dampened cloth or brush – or take other cosmetic steps to improve the look of the surface. Remember that once the cleaning step is complete it’s important to leave a layer of Concrobium Mold Control on the surface to provide mold resistance.
