FortiFlash ®
Performance standards you can trust FortiFlash Waterproof Flashing Membrane features a self-sealing rubberized asphalt core and is designed for use as a concealed flashing in frame construction where a water- proof membrane is required.
Limitations: For optimum adhesion, FortiFlash should be applied at temperatures between 40 °F (4.4 °C) and 120 °F (48.9 °C). Be cautious about using FortiFlash where it can be exposed to temperatures above its Service Temperature such as hot climates or behind fiber cement and metal sidings that absorb a significant amount of heat. Product should be covered as soon as possible (exposure not to exceed 60 days). Inspect product to ensure it is free of any damage which may compromise its moisture-resistive properties. FortiFlash is not compatible with EPDM or flexible (plasticized) Polyvinyl Chloride (PVC) based membranes. Where installed horizontally or with a slope of less than 60° do not use fasteners. FortiFlash also is not compatible with some sealants. Consult with sealant manufacturer for compatibility information. Direct exposure of sealant to the adhesive side of FortiFlash can be detrimental if the amount of sealant exceeds what is specified in Henry’s installation guide. Please follow installation guide recommendations regarding location and amount of sealant to be used. Henry strongly recommends using Moistop ® Sealant for any installation where sealant may come in contact with the FortiFlash adhesive. Installation: Prior to installation, surfaces should be dry and cleaned free of any dirt or other substances that may interfere with adhesion, as well as any sharp protrusions. Surfaces shall have no voids, damaged, or unsupported areas. Repair surfaces before installing membrane. Primer must be used over some substrates including gypsum board (including Dens-Glass Gold), concrete and masonry. For all other substrates field test a small sample of FortiFlash prior to application. If adhesion is inadequate, apply Aquatac™ Primer or 3M Super 77 ® Spray Adhesive according to the manufacturer’s application instructions. Areas not covered with membrane the same day must be re-primed. To apply FortiFlash, peel away the release paper and press membrane firmly over substrate, applying sufficient pressure with a metal or wood roller along the entire membrane to ensure a continuous seal.
