Fiberlock IAQ 5000 Stain Blocking Primer White

Fiberlock IAQ 5000 Stain Blocking Primer White - CommercialVacuum.com

IAQ 5000 is a white, high-performance coating specifically designed to prime stained or water damaged surfaces and to resist mold growth on the coating surface. Use IAQ 5000 on interior or exterior surfaces to prevent most bleeding type stains, seal porous surfaces and provide adhesion to hard and glossy surfaces. IAQ 5000 provides maximum breathability, adhesion and holdout to prolong the life of the finish.

  • Superior Stain Blocking
  • 100% Acrylic Latex
  • Quick drying
  • Excellent adhesion to glossy surface.

How to Use 


Surfaces to be coated must be free of dust, mildew, mold, dirt, grease, loose paint, oil, glue size, calcimine, wax, soap and other surface contamination. Clean mold stained surfaces with IAQ Advanced Peroxide Cleaner, or use an EPA registered antimicrobial disinfectant cleaner such as IAQ 2000, IAQ 2500, ShockWave or ShockWave RTU. Fill nicks, holes and voids with appropriate patching material and sand smooth prior to priming. 


Apply Fiberlock IAQ 5000 with brush, roller or airless sprayer. Brush: Nylon or polyester synthetic bristle Roller: Synthetic fiber 3/8” nap or longer Spray Settings: Pressure 2200 to 2800 P.S.I. Tip: .015 to .017 


Material is supplied at application consistency but can be thinned sparingly with water if necessary to improve application characteristics. Apply with appropriate application equipment. Some stains may require two coats of IAQ 5000; if an active stain discolors the primer, apply an additional coat to a small area to see if the stain is “locked” into the primer. 


Smooth Surfaces: 400-500 sq. ft./gal. Porous Surfaces: 100-300 sq. ft./gal. 


  • @ 70°F 50% R.H 
  • To Touch – 30 minutes 
  • Recoat – 2 hours 


Clean tools and drippings with warm soapy water before Fiberlock IAQ 5000 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 5000 coating is resistant to mold only on the surface of the coating. No mold resistance claim is made other than to the coating itself. 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 with any R, P, N or HE filter. For interior use only.
