If your home or building has fiberglass air ducts, also known duct board or fiberboard, Mold Resistant Duct Coating may be necessary after cleaning and decontamination of the air duct system.
Why would your system require mold resistant duct coating?
Most homes in Florida have fiberglass in some part of the air duct system. The plenum, which is the main duct above the inside air conditioner, is often made of fiberglass. Depending on the design, other parts of the duct system may also be fiberglass. The fiberglass acts a sponge for dust, dirt and even mold. Other situations when your air duct system requires mold resistant coating include heavy dirt buildup, microbial growth or suspect mold in the air-conditioning system, or musty odors coming from the ductwork, among others. Fiberglass air duct systems require cleaning and decontamination in accordance with the National Air Duct Cleaning Association (NADCA) Standards. After cleaning, DuctMasters applies a mold resistant duct coating to seal the fiberglass ductwork and prevent fiberglass and particulate from becoming airborne. If the system cannot be properly cleaned and coated, then air duct replacement may be necessary.
DuctMasters uses IAQ 8000 Antimicrobial Paint to seal the porous ductwork after cleaning. This sealant is a high-performance coating for use in ductwork designed to bridge, reinforce and extend the life of the duct system. We also recommend mold resistant coating for new duct systems because it prevents future microbial growth and extends the life of the system.
