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 Advanced Peroxide Cleaner, or use an EPA-registered antimicrobial disinfectant cleaner such as IAQ 2000, IAQ 2500, ShockWave, or ShockWave RTU. Patch irregularities with vinyl patching paste or an appropriate patching compound. IAQ 6000 is self-priming over bare sheetrock, composition board, ceiling tile, and concrete.


Joint cement should be sanded smooth, but avoid abrading the paper.


Clean, then prime with IAQ 4000 rust-inhibiting direct-to-metal primer.


Seal knots and stains with IAQ 5000 stain-blocking primer.


Apply one coat of IAQ 3000 block filler if a denser surface is desired.


Apply IAQ 6100 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: 2000-3000 P.S.I. Tips: .019 to .021 tips


IAQ 6100 is supplied ready to use but can be thinned sparingly with water (up to 1/2 pint water per gallon) for proper application consistency if necessary. Apply IAQ 6000 generously and uniformly by brush, roller, or airless spray. Apply one coat of IAQ 6000 and ensure that the finished surface is properly sealed. To ensure that the finished surface is properly sealed, two coats may be required on some porous surfaces.


  • Smooth Surfaces- 250-400 sq. ft. per gallon (25-40m2 per 4ltrs)
  • Porous Surfaces- 150-300 sq. ft. per gallon (15-30m2 per 4ltrs)


  • @ 70°F 50% R.H
  • To Touch – 1 Hour

The IAQ 6000 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, 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.
