Fiberlock IAQ 7000... HVAC SEALANT – WHITE

Increase airflow while minimizing dust buildup in HVAC systems with IAQ 7000 HVAC sealant.

IAQ 7000 is a durable, flexible, and moisture-resistant penetrating coating for duct insulation in residential, commercial, or industrial facilities. IAQ 7000 resists mold growth* on the coating surface and can be used as a post-cleaning lockdown of inanimate residual particulates, such as fiberglass, dust, and dirt.

Successfully tested to ASTM standard C-411 “Hot Surface Performance of a Coating on Glass Fiber Blanket Insulation”, ASTM E-84 Class A fire rated, and meets requirements of NFPA 90A/90B standard.

*Resistant to mold growth on the dry coating surface only


  • Meets NFPA 90A/90B
  • Penetrating coating for lined ductwork
  • Lockdown for inanimate particulate contamination

How to Use


Carefully clean up with a wet mop or HEPA vacuum. Clean and remove all dust and loose particulate from ductwork, being careful not to damage insulation. Follow duct manufacturer’s instructions for proper cleaning.


Apply IAQ 7000 with a brush, roller, or airless spray equipment.

  • Brush: Synthetic, nylon, or polyester bristle
  • Roller: Synthetic Fiber 3/8” nap or longer
  • Spray Settings:  Pressure: 2200-3000 P.S.I. Tips: .017 to .023 tips


Prior to application, mix thoroughly to achieve a uniform consistency. Apply IAQ 7000 to all surfaces by brush or airless spray. The application rate will vary depending on the porosity of the insulation. Apply one coat by airless spray, or two coats by brush. Porous surfaces may require additional coats. Ensure that surfaces are completely sealed. Circulate fresh air through the HVAC system to help dry the coating. Exhaust air outside the building.  IAQ 7000 can be applied using HVAC robotic spray applicators (contact Fiberlock for more information).


  • Smooth Surfaces: 100-200 sq. ft./gal.
  • Porous Surfaces: Depends on porosity


  • @ 70°F 50% R.H
  • To Touch – 1 hour
  • To Recoat – 8-16 hours


Clean tools and drippings with warm soapy water before IAQ 7000 dries. Dispose of all waste according to all existing local, state, and federal regulations.


Store in a dry place at temperatures between 40°F (4.5°C) and 90°F. (32°C). Stir thoroughly. Do not mix with any other coatings, solvents, or colors in oil. The IAQ 7000 coating is resistant to mold only on the surface of the coating. No mold resistance claim is made other than to the coating itself. The use of this product does not protect users or others against food-borne or disease-causing bacteria, viruses, germs, or other disease-causing organisms. Do not apply when air or surface temperature is below 50°F, or when drying conditions are poor, or when surfaces are above a 15% moisture level content. Use adequate ventilation during application. When applying with a sprayer, wear a NIOSH-approved respirator with any R, P, N, or HE filter. For interior use only. Check with the local building code enforcement authority for any additional requirements.
