Product Information

Next Generation Mold-Resistant Coating!

IAQ 6000 GEN3 is formulated with a unique fungistatic agent to resist mold growth on the dry coating surface. IAQ 6000 GEN3 is a white, tintable mold-resistant coating for professional use.


IAQ 6000 GEN3 is a durable, flexible, and permeable 100% acrylic water-based coating.


IAQ 6000 GEN3 has been tested by independent and certified laboratories to prove resistance to mold growth on the surface of the coating, and has successfully passed ASTM G-21 mold resistance testing with the highest possible score.


IAQ 6000 GEN3 is recommended for use on wood, plaster, wallboard, sheetrock, concrete, masonry block, primed metal and galvanized metal. IAQ 6000 GEN3 can also be used on new structural materials during building construction.
