*Resists mold on the dry coating surface only


  • White, tintable, high-build coating
  • 100% acrylic, water-based flat coating
  • Ideal for porous material
  • Class A fire rated
  • High-build formula for one-coat coverage

How to Use


Carefully clean up with a wet mop or HEPA vacuum. 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 6000HD 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 6000HD with brush, roller or airless spray equipment.

  • Brush: Synthetic, nylon or polyester bristle
  • Roller: Synthetic fiber 3/8” nap or longer
  • Spray: .021 to .025 tip @ 2000-2800 P.S.I.


IAQ 6000HD may be tinted to any off-white or pastel based color. Add up to 2 oz. of universal colorant per gallon. Start with 50% of the tinting formula and adjust as necessary.


IAQ 6000HD is supplied ready to use, but can be thinned sparingly with water (up to ½ pint water per gallon) for proper application consistency if necessary. Apply IAQ 6000HD generously and uniformly by brush or airless spray. Ensure that the finished surface is properly sealed. To ensure that the finished surface is properly sealed, two-coats may be required on some highly porous surfaces.
