Stop It® Flat Patch

For localized repairs or where full pipe wraps are impractical

STOP IT® Flat Patch is a leak sealant product designed for applications where localized repair is needed or full pipe wraps are impractical. The carbon fiber composite repair system quickly restores operations for storage tanks, floating lids, vessels and large-diameter pipes operating at pressures up to 1,000 psi, and provides localized corrosion inhibition.

  • STOP IT® Flat Patch surface preparation consists of removing any loose scale and lubricants or greases. The surface should be relieved of all pressure until the product is fully applied and cured. Application surfaces should be dried prior to application and warmed if the pipe surface is less than 50°F or cooled if greater than 100°F.
  • Application entails mixing a pre-measured two-part sealant, wetting felt and fibrous reinforcement tape, and applying the fabrics onto the surface. Applications can be made regardless of surface orientation and result in a durable coating with superior pressure-sealing capabilities.
  • Sealant mixing takes seconds and can be immediately applied to the reinforcement tape. The wetted tape possesses a working time of approximately 8-10 minutes. The exact application time will depend on the specific conditions under which STOP IT® FP is being applied.
