Fiberlock AfterShock Fungicidal Coating is a professional-grade antimicrobial coating engineered to address mold and mildew contamination in residential, commercial, and institutional environments. This EPA-registered product is specifically designed to be applied after proper cleaning and removal of visible contamination, where it works to kill residual mold and mildew while helping prevent future growth on the cured coating surface.

Formulated as a high-performance 100% acrylic coating, AfterShock combines durability with ease of application. It creates a resilient protective film that adheres to a variety of interior surfaces, including drywall, plaster, wood, concrete, masonry block, and primed or galvanized metal. The coating is also suitable for use inside wall cavities on framing and structural materials, making it a versatile solution for remediation and restoration projects following water damage or mold exposure.

AfterShock is supplied ready to use and can be applied using brush, roller, or airless spray equipment. Its self-priming properties on many common building materials simplify application, while fast drying times—approximately one hour to the touch and four hours to recoat—help keep projects moving efficiently.

Designed for long-term performance, the coating not only treats residual contamination but also inhibits mold and mildew growth on the surface of the cured film. This dual-action functionality makes it a critical component in comprehensive mold remediation programs. However, it is important to note that AfterShock is not intended for HVAC system applications and should be used only on appropriate interior surfaces.
