Product Details

AfterShock offers the ultimate combination of durability, application ease, and fungal resistance to address mold growth in nearly any situation. The white, antimicrobial coating kills residual mold and mildew remaining after pre-cleaning and disinfecting contaminated surfaces, and inhibits the future growth and spread of mold and mildew. AfterShock is recommended for use on interior wall surfaces in residential, commercial, and institutional buildings.

  • EPA-registered fungicidal coating
  • Kills and prevents mold and mildew
  • 100% acrylic sealant


AfterShock is supplied ready to use. Stir thoroughly. Do not mix with other coatings, solvents or colors in oil. Remove damaged materials and clean surfaces. Surface must be free of dust, mildew, mold, dirt, grease, loose paint, oil, glue size, calcimine, wax, soap and other surface contamination. Patch surface irregularities with an appropriate patching compound. AfterShock is self-priming over bare gypsum drywall, composition board, ceiling tile and concrete. Do not apply when air or surface temperature is below 50°F or when drying conditions are poor. Use adequate ventilation during application.


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


Clean, then prime with Fiberlock IAQ™ 4000 acrylic DTM primer.


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


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


Apply AfterShock 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: .017 to .021 tips


Remove gross filth or heavy soil. For heavily soiled areas, a pre-cleaning step is required. Apply AfterShock generously and uniformly by brush, roller or airless spray and ensure that the surface is completely coated. Allow to air dry. Clean and inspect regularly for damage to coating film – reapply if cured coating film becomes damaged. AfterShock will kill residual mold and mildew on the surface, and then will prevent the growth of mold and mildew on the surface of the cured film.
