Concrobium Mold Control is a non-toxic solution that works through a physical encapsulation process rather than chemical toxicity. Its formula, based on sodium carbonate and polymers, is designed to "crush" spores as it dries, creating a film that helps prevent future growth. Because it contains zero VOCs or bleach, it is a helpful choice for structural work in enclosed areas like attics or crawlspaces where traditional fumes would be hazardous.
This 14.1-ounce aerosol variant is intended to provide uniform coverage and reach into micro-fissures better than a liquid wipe. However, the saline nature of the formula presents a practical hardware challenge; the salt can crystallize at the nozzle interface, which may lead to terminal blockages. To prevent this, users should purge the nozzle after every use to ensure the compressed air propellant can continue to deliver the remaining product.
While the tinplate steel canister is durable, the high pH of the formula can be corrosive if the internal lining has any imperfections. For organizers managing larger projects, the cost-per-ounce is higher than bulk liquid options, and the single-use nature of the aerosol can results in more material waste. It remains a top choice for those prioritizing safety and structural protection without the use of harsh oxidizers.
If you find the aerosol nozzle too prone to clogging, the Concrobium 32-ounce trigger spray offers the same formula in a more traditional and often more reliable delivery system.
