Surface Preparation

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.

Wallboard, Sheetrock, Gypsum Board

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

Ferrous Metal

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


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

Masonry Block

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

Application Tools

Apply Fiberlock IAQ 6000 with brush, roller, or airless spray equipment. Refer to the product application section below for more specific information on settings and which tools to select.

Product Application

Air and surface temperature must be 50°F or above during application and drying period. Fiberlock IAQ 6000 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 Fiberlock IAQ 6000 generously and uniformly by brush, roller or airless sprayer. Ensure that the finished surface is properly sealed.

  • Brush: Synthetic, nylon or polyester bristle
  • Roller: Synthetic fiber 3/8”nap or longer
  • Airless spray settings
    • Pressure: 2000-3000 PSI
    • Tips: .019 to .021 tips


Stir thoroughly. Do not mix with any other coatings, solvents, or colors in oil. Fiberlock IAQ 6000 is resistant to the deteriorating action of mold, mildew, and bacteria. No claim is made for the preservative action to other than the coating film. Do not apply when air or surface temperature is below 50°F or when drying conditions are poor. Keep from freezing. Use adequate ventilation during application.

Clean Up

Clean tools and drippings with warm, soapy water before Fiberlock IAQ 6000 dries. Dispose of all waste according to all existing local, state, and federal regulations.
