Foster® Protective Coating
Why Foster® 40-20 Fungicidal Protective Coating Matters:
Foster® 40-20 acts as a durable protective barrier inside your home’s HVAC duct system, helping prevent the growth of mold and odor-causing bacteria. Over time, moisture within ducts and surrounding materials can create ideal conditions for microbial growth. When left untreated, this can lead to unpleasant odors, system contamination, and potential allergy or respiratory irritation.
This long-lasting fungicidal coating is specifically formulated to maintain its effectiveness as it ages, helping stop mold and bacteria from adhering to treated surfaces. It creates a tough, flexible finish that resists cracking or splitting, reducing areas where contaminants can take hold.
For homeowners, this means cleaner airflow, added protection for your HVAC system, and reduced risk of costly damage caused by hidden mold growth. Applied in areas such as ductwork and other vulnerable surfaces, Foster® 40-20 provides an added layer of defense for both your home and your family’s comfort.
